Description

Technical Field

[0001] This invention relates to the field of aluminum cantilever arms for overhead contact lines, and more specifically to an aluminum cantilever arm production apparatus. Background Technology

[0002] With the rapid development of railway construction in my country, new requirements have been placed on the process quality standards of related components in the railway industry, and the precision requirements for the construction and maintenance of railway lines are becoming increasingly stringent. In railway lines, the overhead contact system is a crucial component ensuring normal railway operation. Connected to the electrified railway power supply lines, it directly undertakes the primary task of supplying energy to electric trains. The cantilever arm is the support device for the overhead contact system, and its pre-assembly is an important aspect of electrified railway construction. High-speed railways have extremely high precision requirements for overhead contact system installation. Since most components of high-speed railway overhead contact system projects cannot be repeatedly disassembled and reassembled, the cantilever arm support device must be precisely assembled in one go after accurate calculations. Due to constraints such as high altitude conditions on site, a pre-fabrication method based on ground batches is necessary. The quality of this one-time installation of the entire contact suspension directly affects the quality, progress, and efficiency of subsequent construction. In the production process of the aluminum cantilever arm, a single lug needs to be fitted onto the inclined cantilever arm and the flat cantilever arm. Then, the flat cantilever arm and the inclined cantilever arm are respectively inserted into the two sleeve seats of the sleeve seat 16. A load-bearing cable seat 26 is fitted onto one end of the flat cantilever arm, and then the fastening bolts on the load-bearing cable seat 26 and the sleeve seat 16 are tightened. The following technical difficulties exist in the aforementioned production process, making it difficult to automate the production of the aluminum cantilever arm:

[0003] 1) The cantilever tube is a long tube structure. The installation direction of the single ear, sleeve seat and load-bearing cable seat on the cantilever tube is required. Moreover, the installation position of the aforementioned accessories is irregular. When assembling with the cantilever tube, the conveying of the cantilever tube needs to be stopped at any time to install the aforementioned accessories. The cantilever tube needs to be rotated continuously to ensure that the direction of the single ear, sleeve seat or load-bearing cable seat installed on the cantilever tube meets the requirements. In the existing technology, the single ear, load-bearing cable seat and sleeve seat are mostly put on the cantilever tube manually and the orientation is adjusted, resulting in low assembly efficiency.

[0004] 2) such as Figure 13 As shown, the single ear includes a single ear platform portion b61, a single ear collar b62, and a single ear connecting portion b63. ​​The two ends of the single ear collar b62 extend beyond the bottom surfaces of both ends of the single ear platform portion b61 and are secured with nuts. The outer surface of the single ear connecting portion b63 is an arc surface and is longitudinally located at the lower end of the single ear platform portion b61. Currently, in the automated production of carousels, when installing the single ear onto the carousel tube, continuous material replenishment of the single ear is required to adapt to the automated production process. Due to the special structure of the single ear, storage is difficult, and currently there is no suitable method for its storage. Figure 13The continuous feeding device for the single ear requires manual feeding, which leads to increased labor costs and low feeding efficiency for the single ear during the production process of the carpal tunnel.

[0005] 3) such as Figure 20 As shown, the sleeve base 16 includes sleeve I 161, sleeve II 162 and connecting part 163 in the sleeve base. Sleeve I 161 and sleeve II 162 are both round tubes, which are not convenient for stable placement. Therefore, a special continuous feeding device and storage device are required to facilitate the assembly of the flat and inclined arms.

[0006] 4) such as Figure 26 As shown, the load-bearing cable seat 26 includes a horizontal tube portion 261, a lug portion 262, a vertical tube portion 263, a locking portion 264, and a cable support clamp 265. When assembling the load-bearing cable seat 26 with the flat cantilever arm, the locking portion 264 must be placed facing upwards to meet the requirements. The horizontal tube portion 261 and the vertical tube portion 263 are perpendicular to each other and are both cylindrical. Furthermore, the other end of the vertical tube portion 263 is equipped with a cable support clamp 265. This results in an unbalanced weight distribution on both sides of the horizontal tube portion 261, making it prone to tilting towards the cable support clamp 265. These structural features make it difficult to place stably. Therefore, a special continuous feeding device and storage device are required to facilitate the assembly of the flat cantilever arm.

[0007] 5) In the assembly process of the single-ear sleeve seat and the load-bearing cable seat with the cantilever tube, there is currently no suitable automatic tightening device. The existing technology uses manual tightening, which not only leads to low efficiency, but also uneven tightening force, resulting in inconsistent assembly firmness of the sleeve seat and the load-bearing cable seat with the cantilever tube and a high rework rate.

[0008] 6) The entire processing of aluminum cantilever arm requires continuously picking up the sleeve seat and the load-bearing cable seat from the conveying device and placing them on the assembly table. Then, the flat cantilever arm and the inclined cantilever arm are conveyed to the assembly table for assembly. Finally, the load-bearing cable seat and the sleeve seat are tightened and fixed to the cantilever arm tube. When designing the aluminum cantilever arm processing production line, the interference between the various processing devices must also be considered.

[0009] In view of this, the present invention provides an aluminum cantilever arm production device that realizes automatic feeding of cantilever arm tubes, automatic feeding, automatic assembly, and automatic tightening of single ears, sleeve seats, and load-bearing cable seats, thereby realizing automated production of aluminum cantilever arms and improving the production efficiency of aluminum cantilever arms. Summary of the Invention

[0010] The present invention aims to provide an aluminum cantilever arm production device to overcome the shortcomings of the prior art. The technical problem to be solved by the present invention is achieved through the following technical solution.

[0011] An aluminum cantilever arm production apparatus includes a single-ear pre-assembly assembly and an accessory assembly located to the left of the single-ear pre-assembly assembly. ，

[0012] The single-ear pre-assembly assembly includes a single pre-rail module and a single-ear pickup module. A single-ear conveying device is located at the right rear of the single pre-rail module. A single pre-feed tube module is mounted on the single pre-rail module. Multiple single pre-support clamping modules are located to the side of the single pre-rail module, to the left of the single pre-feed tube module. Multiple single pre-support frame modules are located to the left of the single pre-support clamping module, and these modules are aligned with the single pre-support clamping module. A single pre-tightening module is located on the single pre-rail module and to the left of the single pre-feed tube module. A single pre-pull tube module is also mounted on the single pre-rail module. The ear conveying device is used to continuously supply single ears to the aluminum cantilever production line. The single ear picking module is used to pick up a single ear from the single ear conveying device and transfer it between adjacent single pre-support pressing modules. The single pre-feed tube module is used to clamp the cantilever tube and continue to convey it to the left so that the cantilever tube passes through the single ear. The single pre-support pressing module is used to support and press the cantilever tube conveyed by the single pre-feed tube module. The single pre-tightening module is used to move to the bottom of the single ear and lock the single ear and the cantilever tube. The single pre-pull tube module is used to clamp the cantilever tube conveyed by the single pre-feed tube module and continue to convey it to the left. The single pre-support frame module is used to support the cantilever tube conveyed by the single pre-pull tube module.

[0013] The component assembly includes a sleeve seat conveying device, a load-bearing cable seat conveying device, a slanted cantilever arm clamping and pushing device, a feeding pusher device, a flat cantilever arm clamping and pushing device, an assembly workbench, a slanted cantilever arm support device, a tightening device, and a ground rail assembly. The load-bearing cable seat conveying device and the sleeve seat conveying device are arranged side by side in front of the ground rail assembly. The slanted cantilever arm clamping and pushing device is mounted on the ground rail assembly and can move relative to the ground rail assembly, used to clamp and fix the cantilever arm tube, rotate it around its own axis, and push it. The feeding pusher device is mounted on the ground rail assembly and can move relative to the ground rail assembly, used to grab the load-bearing cable seat and the sleeve seat and place them on the assembly workbench, install the guide cone on the end of the cantilever arm tube, and... The guide cone is removed from the end of the cantilever tube; the flat cantilever clamping and pushing device is installed on the ground rail assembly and can move relative to the ground rail assembly, used to clamp and fix the cantilever tube, rotate it around its own axis, and push it; the assembly workbench is located on the side of one end of the ground rail assembly, and the assembly workbench is provided with an assembly workbench load-bearing cable seat storage rack, an assembly workbench sleeve seat storage rack, an assembly workbench flat cantilever pressing device I, an assembly workbench flat cantilever pressing device II, and an assembly workbench inclined cantilever pressing device; the inclined cantilever support device is located on the side of the ground rail assembly and is used to support the cantilever tube; the tightening device is installed on the ground rail assembly and can move relative to the ground rail assembly, used to tighten the fastening bolts under the sleeve seat and the load-bearing cable seat.

[0014] In this invention, during production, firstly, the single-ear conveying device continuously supplies single ears to the aluminum cantilever production line. The single-ear picking module picks up the single ear from the single-ear conveying device and transfers it between two adjacent single pre-support clamping modules. Preferably, the single-ear picking module transfers the single ear between the two single pre-support clamping modules closest to the single pre-support frame module. Then, the single pre-feeding tube module clamps the cantilever tube conveyed from the previous station and continues to convey it to the left so that the cantilever tube passes through the single ear. When the cantilever tube is long enough, it can also directly pass through the single ear while being conveyed from the previous station. In this case, the single pre-feeding tube module only serves to clamp the cantilever tube and continue to convey it to the left. Then, the single pre-pulling tube module clamps the conveyed cantilever tube and continues to convey it to the left. During the transport of the carpal tube, when the carpal tube reaches the position of the pre-fitted single ear, the transport is paused, the single pre-support clamping module clamps the carpal tube, and the single pre-tightening module moves below the single ear to lock the single ear and the carpal tube.

[0015] The cantilever tube includes a flat cantilever and an angled cantilever. Single ears are installed on both the flat and angled cantilever arms using the aforementioned method. Then, the feeding pusher device grabs the sleeve seat and load-bearing cable seat from the sleeve seat conveyor and load-bearing cable seat conveyor, respectively, and places them on the assembly table sleeve seat storage rack and load-bearing cable seat storage rack. The truss gripper above the production line grabs the flat cantilever arm from the single pre-support frame module. The single pre-tension tube module and single pre-support clamping module release the cantilever tube. The truss gripper above the production line transports the flat cantilever arm to the right side of the assembly table. The flat cantilever arm clamping and pushing device clamps the right end of the flat cantilever arm. The feeding pusher device installs a guide cone on the left end of the flat cantilever arm to ensure smooth insertion of the flat cantilever arm into the sleeve seat and load-bearing cable seat. The flat cantilever arm clamping and pushing device rotates the flat cantilever arm so that the direction of the single ear installed on the right end of the flat cantilever arm conforms to... The requirements are as follows: under the combined action of the flat cantilever arm clamping and pushing device and the truss gripper, the flat cantilever arm is inserted from right to left into the sleeve I of the sleeve seat and the horizontal tube of the load-bearing cable seat. Then, the assembly table flat cantilever arm pressing device I and the assembly table flat cantilever arm pressing device II are respectively pressed above the left and right ends of the flat cantilever arm to fix the flat cantilever arm on the assembly table. Then, the flat cantilever arm clamping and pushing device releases the right end of the flat cantilever arm, and the feeding push head device moves to the left side of the assembly worktable to remove the guide cone from the left end of the flat cantilever arm.

[0016] Similarly, the truss gripper above the production line grabs the inclined arm on the single pre-support frame module and transports it to the right side of the assembly workbench, placing it on the inclined arm support device. The inclined arm clamping and pushing device clamps the right end of the inclined arm, and the feeding pusher moves to the left side of the inclined arm, installing the guide cone at the left end of the inclined arm to allow the inclined arm to smoothly pass through the sleeve seat. The inclined arm clamping and pushing device rotates the inclined arm to ensure that the two single ears installed on the inclined arm are in the correct orientation. Then, the inclined arm clamping and pushing device pushes the inclined arm so that it passes through the sleeve II of the sleeve seat from right to left. After that, the assembly table inclined arm pressing device presses and fixes the inclined arm. Then, the inclined arm clamping and pushing device releases the right end of the inclined arm, and the feeding pusher moves to the left side of the inclined arm to remove the guide cone from the left end of the inclined arm. The tightening devices move to the bottom of sleeve II and tighten the fastening bolts at the bottom of sleeve II. The truss tightening devices above the production line tighten the fastening bolts on the upper side of the load-bearing cable seat and the sleeve seat respectively, so as to fix the sleeve seat and the load-bearing cable seat on the cantilever tube. Thus, the processing and production of the aluminum cantilever arm is completed.

[0017] This invention provides an aluminum cantilever arm production device. Compared with the prior art, it realizes automatic feeding of cantilever arm tubes, automatic feeding, automatic assembly, and automatic tightening of single ears, sleeve seats, and load-bearing cable seats. It ensures the accuracy of the assembly position of single ears, sleeve seats, and load-bearing cable seats and the uniformity of the locking force, thereby realizing the automated production of aluminum cantilever arms and improving work efficiency and product qualification rate.

[0052] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

A single pre-pulling tube module a3 is also located on the single pre-rail module a1. The single-ear conveying device b is used to continuously supply single-ear b6 to the aluminum cantilever production line. The single-ear picking module a8 is used to pick up single-ear b6 from the single-ear conveying device b and transfer it between the adjacent single pre-support pressing module a7. The single pre-feeding tube module a6 is used to clamp the cantilever tube and continue to convey it to the left so that the cantilever tube passes through the single-ear b6. The single pre-support pressing module a7 is used to support and press the cantilever tube conveyed by the single pre-feeding tube module a6. The single pre-tightening module a4 is used to move to the bottom of the single-ear b6 and lock the single-ear and the cantilever tube. The single pre-pulling tube module a3 is used to clamp the cantilever tube conveyed by the single pre-feeding tube module a6 and continue to convey it to the left. The single pre-support frame module a2 is used to support the cantilever tube conveyed by the single pre-pulling tube module a3.

[0056] The component assembly includes a sleeve seat conveying device 10, a load-bearing cable seat conveying device 20, a slanted cantilever arm clamping and pushing device 30, a feeding pusher device 40, a flat cantilever arm clamping and pushing device 50, an assembly workbench 60, a slanted cantilever arm support device 70, a tightening device 80, and a ground rail assembly 90. The load-bearing cable seat conveying device 20 and the sleeve seat conveying device 10 are arranged side by side in front of the ground rail assembly 90. The slanted cantilever arm clamping and pushing device 30 is mounted on the ground rail assembly 90 and can move relative to the ground rail assembly 90, and is used to clamp and fix the cantilever arm tube, rotate it around its own axis, and push it. The feeding pusher device 40 is mounted on the ground rail assembly 90 and can move relative to the ground rail assembly 90, and is used to grab the load-bearing cable seat 26 and the sleeve seat 16 and place them on the assembly workbench 60, and to install the guide cone 49 on the cantilever arm. The guide cone 49 is removed from the end of the tube; the flat arm clamping and pushing device 50 is installed on the ground rail assembly 90 and can move relative to the ground rail assembly 90, used to clamp and fix the arm tube, rotate it around its own axis and push it; the assembly workbench 60 is located on the side of one end of the ground rail assembly 90, and the assembly workbench 60 is provided with an assembly workbench load-bearing cable seat storage rack 65, an assembly workbench sleeve seat storage rack 67, an assembly workbench flat arm pressing device I, an assembly workbench flat arm pressing device II and an assembly workbench oblique arm pressing device; the oblique arm support device 70 is located on the side of the ground rail assembly 90 and is used to support the arm tube; the tightening device 80 is installed on the ground rail assembly 90 and can move relative to the ground rail assembly 90, used to tighten the fastening bolts under the sleeve seat 16 and the load-bearing cable seat 26.

[0057] In this embodiment, during production, firstly, the single-ear conveying device b continuously supplies single-ear b6 to the aluminum cantilever production line. The single-ear picking module a8 picks up the single-ear b6 from the single-ear conveying device b and transfers it between two adjacent single pre-support pressing modules a7. Preferably, the single-ear picking module a8 transfers the single-ear b6 between the two single pre-support pressing modules a7 closest to the single pre-support frame module a2. Then, the single pre-feeding tube module a6 clamps the cantilever tube conveyed from the previous station and continues to convey it to the left so that the cantilever tube passes through the single-ear b6. When the cantilever tube is long enough, it can also directly pass through the single-ear b6 under the conveying of the previous station. In this case, the single pre-feeding tube module a6 only serves to clamp the cantilever tube and continue to convey it to the left. Then, the single pre-pulling tube module a3 clamps the conveyed cantilever tube and continues to convey it to the left. During the transport of the carpal tube, when the carpal tube reaches the position of the pre-fitted single ear b6, the transport is paused, the single pre-support clamping module a7 clamps the carpal tube, and the single pre-tightening module a4 moves below the single ear b6 to lock the single ear b6 and the carpal tube.

[0058] The cantilever tube includes a flat cantilever and an inclined cantilever. A single ear is installed on both the flat cantilever and the inclined cantilever using the aforementioned method. Then, the feeding pusher device 40 grabs the sleeve seat 16 and the load-bearing cable seat 26 from the sleeve seat conveying device 10 and the load-bearing cable seat conveying device 20, respectively, and places them on the assembly table sleeve seat storage rack 67 and the assembly table load-bearing cable seat storage rack 65 on the assembly workbench. The truss gripper above the production line grabs the flat cantilever arm on the single pre-support frame module a2. The single pre-tension tube module a3 and the single pre-support clamping module a7 release the cantilever arm tube. The truss gripper above the production line transports the flat cantilever arm to the right side of the assembly workbench 60. The flat cantilever arm clamping and pushing device 50 clamps the right end of the flat cantilever arm. The feeding pusher device 40 installs the guide cone 49 on the left end of the flat cantilever arm so that the flat cantilever arm can be smoothly inserted into the sleeve seat 16 and the load-bearing cable seat 26. The flat cantilever arm clamping and pushing device 50 rotates the flat cantilever arm so that the direction of the single ear installed on the right end of the flat cantilever arm is in accordance with the direction of the single ear. The requirements are as follows: under the combined action of the flat cantilever arm clamping and pushing device 50 and the truss gripper, the flat cantilever arm is inserted from right to left into the sleeve I161 of the sleeve seat 16 and the horizontal tube 261 of the load-bearing cable seat 26. Then, the assembly table flat cantilever arm pressing device I and the assembly table flat cantilever arm pressing device II are respectively pressed above the left and right ends of the flat cantilever arm to fix the flat cantilever arm on the assembly table. Then, the flat cantilever arm clamping and pushing device 50 releases the right end of the flat cantilever arm, and the feeding push head device 40 moves to the left side of the assembly worktable 60 to remove the guide cone 49 from the left end of the flat cantilever arm.

[0059] Similarly, the truss gripper above the production line grabs the inclined arm on the single pre-support frame module a2 and transports it to the right side of the assembly workbench 60, placing it on the inclined arm support device 70. The inclined arm clamping and pushing device 30 clamps the right end of the inclined arm, and the feeding pusher device 40 moves to the left side of the inclined arm, installing the guide cone 49 at the left end of the inclined arm so that the inclined arm can smoothly pass through the sleeve seat 16. The inclined arm clamping and pushing device 30 rotates the inclined arm so that the two single ears installed on the inclined arm are in the correct orientation. Then, the inclined arm clamping and pushing device 30 pushes the inclined arm so that the inclined arm passes through the sleeve II 162 of the sleeve seat 16 from right to left. After that, the assembly table inclined arm pressing device presses and fixes the inclined arm. Then, the inclined arm clamping and pushing device 30 releases the right end of the inclined arm, and the feeding pusher device 40 moves to the left side of the inclined arm and removes the guide cone 49 from the left end of the inclined arm. Tightening device 80 moves to the bottom of sleeve II162 and tightens the fastening bolts below sleeve II162. The truss tightening device above the production line tightens the fastening bolts on the upper side of load-bearing cable seat 26 and sleeve seat 16 respectively, so as to fix sleeve seat 16 and load-bearing cable seat 26 on the cantilever tube. Thus, the processing and production of aluminum cantilever arm is completed.

[0060] This embodiment provides an aluminum cantilever arm production device. Compared with the prior art, it realizes automatic feeding of cantilever arm tubes, automatic feeding, automatic assembly, and automatic tightening of single ears, sleeve seats, and load-bearing cable seats. It ensures the accuracy of the assembly position of single ears, sleeve seats, and load-bearing cable seats and the uniformity of the locking force, realizing the automated production of aluminum cantilever arms and improving work efficiency and product qualification rate.

[0061] Furthermore, refer to Figure 6 As shown, the single pre-feed tube module a6 includes a single pre-feed tube base a61 disposed on the single pre-rail module a1, a single pre-feed tube movement driver a63 disposed on the single pre-feed tube base a61 and driving the single pre-feed tube base a61 to move relative to the single pre-rail module a1, and a single pre-feed tube support a62 disposed on the single pre-feed tube base a61. The single pre-feed tube support a62 is provided with a single pre-feed tube clamping driver a64. The telescopic end of the single pre-feed tube clamping driver a64 is connected to a single pre-feed tube gripper a65. The single pre-feed tube gripper a65 is used to clamp the wrist arm tube.

[0062] Furthermore, refer to Figure 3 As shown, the single pre-support frame module a2 includes a single pre-support column a21 and a single pre-support lifting cylinder a22 disposed on the single pre-support column a21. The telescopic end of the single pre-support lifting cylinder a22 is provided with a single pre-support connecting plate a23, and the single pre-support connecting plate a23 is provided with a single pre-support roller a24. The single pre-support roller a24 is used to support the carpenter arm tube.

[0063] In this embodiment, the single pre-support lifting cylinder a22 and the single pre-support connecting plate a23 are designed to avoid interference between the single pre-support frame module a2 and the single pre-tensioning pipe module a3 during the transport of the cantilever tube.

[0064] Example 2:

[0065] Based on Example 1, referring to Figure 7As shown, the single pre-support clamping module a7 includes a single pre-support clamping column a71, a single pre-support clamping lifting driver a72 disposed on the single pre-support clamping column a71, a single pre-support clamping connecting plate a74 disposed on the telescopic end of the single pre-support clamping lifting driver a72, a single pre-support clamping roller a77 disposed on the single pre-support clamping connecting plate a74, and a single pre-support clamping roller a77 disposed on the single pre-support clamping connecting plate a74 and located on the single pre-support clamping roller a77. A single pre-support clamping actuator a75 is located on the side of 77. A single pre-support clamping block a76 is provided on the telescopic end of the single pre-support clamping actuator a75. The single pre-support clamping block a76 moves up and down relative to the single pre-support clamping roller a77 under the drive of the single pre-support clamping actuator a75 to release or clamp the wrist arm tube. The single pre-support clamping block a76 rotates relative to the single pre-support clamping actuator a75 under the drive of the single pre-support clamping actuator a75.

[0066] Furthermore, a single pre-support pressing lifting drive a72 and a single pre-support pressing connecting plate a74 are provided with a single pre-support pressing lifting plate a73, which is used to provide a sliding track for the single pre-support pressing connecting plate a74 to move up and down relative to the single pre-support pressing lifting drive a72.

[0067] In this embodiment, the reason for setting up a single pre-support clamping lifting driver a72 is that when the single pre-support clamping connecting plate a74 and its single pre-support clamping roller a77 are in the position supporting the arm tube, they will interfere with the conveying of the arm tube, especially the conveying of the arm tube equipped with a single ear. Similarly, the reason for setting up a single pre-support clamping block a76 to rotate relative to the single pre-support clamping driver a75 under the drive of the single pre-support clamping driver a75 is also to avoid interference of the single pre-support clamping module a7 with the conveying of the arm tube. The reason for setting up a single pre-support clamping block a76 to move up and down relative to the single pre-support clamping roller a77 under the drive of the single pre-support clamping driver a75 to loosen or clamp the arm tube is to ensure the stability of the arm tube when the single pre-tightening module a4 locks the single ear and the arm tube, and to prevent the arm tube from shifting due to locking.

[0068] Example 3:

[0069] Based on Example 1 or 2, refer to Figure 4As shown, the single pre-tensioned tube module a3 includes a single pre-tensioned tube base a31 disposed on the single pre-rail module a1, a single pre-tensioned tube moving driver a33 disposed on the single pre-tensioned tube base a31 and driving the single pre-tensioned tube base a31 to move relative to the single pre-rail module a1, and a single pre-tensioned tube support a32 disposed on the single pre-tensioned tube base a31. The single pre-tensioned tube support a32 is provided with a single pre-tensioned tube clamping driver a36. The single pre-tensioned tube clamping driver a36 drives the single pre-tensioned tube gripper a37 to clamp or release to hold or release the wrist arm tube.

[0070] Furthermore, the single pre-tensioned tube support a32 is provided with a single pre-tensioned tube connecting plate a34, and the single pre-tensioned tube clamping driver a36 is provided on the single pre-tensioned tube support a32 through the single pre-tensioned tube connecting plate a34.

[0071] Furthermore, the single pre-tensioned tube connecting plate a34 is provided with a single pre-tensioned tube rotary driver a35, and the single pre-tensioned tube clamping driver a36 is connected to the single pre-tensioned tube rotary driver a35. The single pre-tensioned tube rotary driver a35 drives the single pre-tensioned tube clamping driver a36 to rotate, thereby driving the wrist arm tube held by the single pre-tensioned tube gripper a37 to rotate.

[0072] In this embodiment, the reason why the single pre-tensioned tube gripper a37 needs to be set on the single pre-tensioned tube support a32 via the single pre-tensioned tube connecting plate a34 is to avoid interference from the single pre-support clamping module a7 and the single pre-support frame module a2 on the single pre-tensioned tube module a3 when conveying the cantilever tube; the reason why the single pre-tensioned tube rotary driver a35 is needed to drive the single pre-tensioned tube clamping driver a36 to rotate, thereby driving the cantilever tube held by the single pre-tensioned tube gripper a37 to rotate is... Because the orientation of the single ear b6 installed on the carousel tube is required, that is, some bolts of the single ear b6 face upwards and some face downwards, and the single pre-tightening module a4 can only lock the downward-facing bolts, when the bolts of the single ear b6 need to face upwards, the single pre-tension tube rotary driver a35 drives the single pre-tension tube clamping driver a36 to rotate, thereby driving the carousel tube held by the single pre-tension tube gripper a37 to rotate. At this time, after locking the bolts of the single ear b6, the carousel tube is rotated again, and the bolts of the single ear b6 will meet the requirement of facing upwards.

[0073] Example 4:

[0074] Based on any of the foregoing embodiments, refer to Figure 5As shown, it also includes a single pre-fixed support module a5, which is located on the side of the single pre-rail module a1 near the end of the single pre-support clamping module a7. The single pre-fixed support module a5 and the multiple single pre-support clamping modules a7 are located on the same straight line. The single pre-fixed support module a5 is equipped with a single pre-fixed support marking machine a57, which is used to mark the cartilage tube.

[0075] Furthermore, the single pre-fixed support module a5 includes a single pre-fixed support column a51, a single pre-fixed support connecting plate a52 and a single pre-fixed support mounting plate a54 disposed on the single pre-fixed support column a51. The single pre-fixed support connecting plate a52 is provided with a single pre-fixed support roller a53 for supporting the arm tube. The single pre-fixed support mounting plate a54 is provided with a single pre-fixed support telescopic actuator a55. The telescopic end of the single pre-fixed support telescopic actuator a55 is provided with a single pre-fixed support moving plate a56. The single pre-fixed support marking machine a57 ​​is disposed on the single pre-fixed support moving plate a56.

[0076] In this embodiment, the single pre-fixed support marking machine a57 ​​can mark information such as the installation position, structural features, specifications, and production date of the aluminum cantilever arm on the cantilever tube, thereby facilitating the subsequent use and maintenance of the aluminum cantilever arm; the single pre-fixed support roller a53 can be used to support the cantilever tube; the single pre-fixed support telescopic driver a55 can adjust the distance between the single pre-fixed support marking machine a57 ​​and the cantilever tube, thereby facilitating marking, and can also extend to mark when marking is needed and retract when marking is not needed to avoid interference with the conveying of the cantilever tube.

[0077] Example 5:

[0078] Based on any of the foregoing embodiments, refer to Figure 9 and Figure 14As shown, the single-ear conveying device b includes a single-ear conveying base b1, and a single-ear drive motor b2 is installed on one side of the single-ear conveying base b1; a single-ear conveying frame b3 is installed above the single-ear conveying base b1, and a single-ear rotary conveying device is installed on the single-ear conveying frame b3; several single-ear storage racks b5 are horizontally arranged side by side on the single-ear rotary conveying device, and each single-ear storage rack b5 includes several vertically arranged single-ear storage units b51. Each single-ear storage unit b51 is used to place a single ear b6, and each single-ear storage unit b51 includes a single-ear connecting portion receiving groove b512 and a single ear connecting portion receiving groove b512 located respectively. 2. Single ear collar positioning components b511 on the front and rear sides. After the single ear b6 is placed on the single ear storage unit b51, the two single ear collar ends b621 of the single ear collar b62 are respectively placed in the single ear collar positioning component b511, and the single ear connecting part b63 is placed in the single ear connecting part receiving groove b512. The single ear drive motor b2 is connected to the single ear rotary conveyor. The single ear drive motor b2 drives the single ear rotary conveyor to rotate. The single ear rotary conveyor drives the single ear storage rack b5 installed on it to rotate. The single ear b6 placed on the single ear storage rack b5 is continuously supplied with replenishment material to the aluminum cantilever production line.

[0079] In this embodiment, the single-ear conveyor base b1 supports the entire single-ear conveying device, and the single-ear drive motor b2 provides power to the single-ear rotary conveyor. When the single-ear conveying device is working, the operator places the single ear b6 on the single-ear storage rack b5. The single-ear drive motor b2 drives the single-ear rotary conveyor to rotate, conveying the single ear b6 to the target position. Then, the single-ear picking module a8 fixes and picks up the single ear b6 and transfers it to the next workstation, thereby realizing the continuous supply of single ear b6 in the aluminum cantilever production line.

[0080] like Figure 14 As shown, the single ear b6 includes a single ear platform part b61, a single ear collar b62 and a single ear connecting part b63. ​​The two ends of the single ear collar b62 extend out of the bottom surfaces of the two ends of the single ear platform part b61 and are locked and fixed by nuts, and are longitudinally located at the lower end of the single ear platform part b61. The difficulty in automating the transport of a single ear b6 with the aforementioned specific shape lies in the fact that the arm tube needs to be inserted into the circular space enclosed by the single ear collar b62 and the single ear platform b61. When the single ear picking module a8 grasps the single ear b6, it needs to avoid the left and right sides of the single ear b6 and can only grasp it from the front and back sides. The thickness between the front and back sides of the single ear connecting part b63 is relatively thin, making it difficult to grasp and fix. Therefore, it is necessary to grasp and fix the front and back sides of the single ear platform b61 or the single ear collar b62. Thus, when placing the single ear b6, the single ear connecting part b63 needs to be placed downwards, and the shaking of the single ear b6 must be avoided during the transport process.

[0081] Therefore, in this embodiment, the single ear storage rack b5 is provided with a single ear storage unit b51, and the single ear storage unit b51 is provided with a single ear connecting part receiving groove b512 for receiving the downward protruding single ear connecting part b63. ​​Two single ear collar positioning parts b511 are used to receive the ends of the single ear collars, which support the single ear b6 while restricting the single ear b6's degrees of freedom except for vertical movement, ensuring the placement stability of the single ear b6 during the conveying process. After the single ear b6 is placed on the single ear storage rack b5, the single ear collar b62 is exposed above the single ear storage rack b5, which is convenient for the single ear picking module a8 to grasp, thereby facilitating the automated replenishment of the single ear b6. The single ear b6 is placed longitudinally on the single ear storage rack b5, which allows more single ears to be accommodated in the horizontal direction, making the structure more compact. Moreover, the single ear storage rack b5 is provided with different numbers of single ear storage units b51 according to needs, which shortens the overall length of the production line while meeting the production line's production requirements.

[0082] This embodiment achieves continuous material supply to single ears b6 with a specific structure by setting up a single ear storage rack b5 with a special structure. This solves the problem in the prior art that the lack of a dedicated storage rack for single ears makes it impossible to achieve automated material supply to single ears, thus providing technical support for the automated production of aluminum cantilever arms.

[0083] Furthermore, the single-ear collar positioning component b511 has a single-ear positioning stepped groove b5111 in the middle, and the single-ear positioning stepped groove b5111 matches the size of the single-ear collar end b621 after it is assembled with the nut.

[0084] Furthermore, the single ear storage unit b51 on the single ear storage holder b5 is two.

[0085] Example 6:

[0086] Based on Example 5, referring to Figure 10 As shown, the single-ear rotary conveying device includes a single-ear conveying driven shaft b48 and a single-ear conveying driving shaft b47, which are respectively longitudinally installed at the left and right ends of the single-ear conveying frame b3. The front and rear ends of the single-ear conveying driving shaft b47 are respectively equipped with single-ear conveying driving wheels b44, and the front and rear ends of the single-ear conveying driven shaft b48 are respectively equipped with single-ear conveying driven wheels b45. The single-ear conveying driving wheel b44 and the single-ear conveying driven wheel b45 located on the same side of the single-ear conveying frame b3 are connected by a single-ear conveying transmission chain b46. The single-ear drive motor b2 is connected to the single-ear conveying driving shaft b47, and the two ends of the single-ear storage rack b5 are respectively installed on the two single-ear conveying transmission chains b46.

[0087] Furthermore, a single-ear transmission chain side bracket is provided on one side of the single-ear transmission chain b46, and the two ends of the single-ear storage rack b5 are respectively fixedly connected to the single-ear transmission chain side bracket.

[0088] Furthermore, the front and rear sides of the single ear storage rack b5 are respectively provided with a single ear storage rack overlapping platform Ib52 and a single ear storage rack overlapping platform IIb53, which are respectively overlapped and installed on the side support of the single ear transmission chain.

[0089] Furthermore, the single ear storage rack mounting platform Ib52 and the single ear storage rack mounting platform IIb53 are respectively provided with single ear storage rack mounting holes b54.

[0090] Furthermore, the single-ear delivery frame b3 includes a plurality of single-ear frame support shafts b33 and single-ear frame side plates Ib31 and IIb32 located on the front and rear sides of the single-ear frame support shafts b33 and fixedly connected to the single-ear frame support shafts b33.

[0091] In this embodiment, the single-ear conveying frame b3 adopts a structure with two side plates and a support shaft, which can reduce the weight of the frame and save the frame material while ensuring the support stability of the frame. At the same time, it can avoid the position of the single-ear rotary conveying device, making the structure of the whole device more compact.

[0092] Furthermore, the output end of the single-ear drive motor b2 is connected to a single-ear drive drive wheel b41, and one end of the single-ear conveying drive shaft b47 is connected to a single-ear drive driven wheel b42. The single-ear drive drive wheel b41 and the single-ear drive driven wheel b42 are connected through a single-ear drive transmission chain b43.

[0093] In this embodiment, the output shaft of the single-ear drive motor b2 rotates, causing the single-ear drive drive wheel b41 to rotate. Then, the single-ear drive driven wheel b42 rotates through the single-ear drive transmission chain b43, thereby driving the single-ear conveying drive shaft b47 to rotate. This causes the single-ear conveying drive wheels b44, which are installed at both ends of the single-ear conveying drive shaft b47, to rotate. Then, the single-ear conveying driven wheel b45 rotates through the single-ear conveying transmission chain b46, thereby achieving continuous and stable rotation of the single-ear conveying transmission chain b46. This continuously conveys the single ear b6 located above the single-ear conveying transmission chain b46 to the target position.

[0094] Furthermore, the single-ear drive motor b2 is a right-angle output motor. A right-angle output motor saves more front and rear space in the entire device, making the overall structure more compact and reducing the footprint of the device, thereby saving space in the entire production line.

[0095] Furthermore, refer to Figure 11 As shown, a single-ear conveying guide bar b35 is installed on the single-ear conveying frame b3 below the single-ear conveying transmission chain b46. The upper end of the single-ear conveying guide bar b35 is provided with a boss. The boss is placed between the inner side plates of the single-ear transmission chain on both sides of the single-ear conveying transmission chain b46, and the width of the boss matches the length of the single-ear transmission chain central axis of the single-ear conveying transmission chain b46.

[0096] In this embodiment, the single-ear conveying guide strip b35 serves two purposes. First, it supports the bottom of the single-ear conveying transmission chain b46, preventing it from bending and deforming due to the weight of the single-ear storage rack b5 and the single ear b6. This prevents the service life of the single-ear conveying transmission chain b46 and the efficiency of the single-ear conveying device from being affected. Second, the boss is positioned between the inner plates of the single-ear transmission chain on both sides of the single-ear conveying transmission chain b46, and the width of the boss matches the length of the central shaft of the single-ear transmission chain b46. This allows the boss to guide the movement of the single-ear conveying transmission chain b46, preventing it from swaying or shifting during movement, thus making the rotational conveying of the single ear more stable and smooth.

[0097] Furthermore, a single-ear conveying support plate b34 is installed between the two side plates of the single-ear conveying frame b3, and the single-ear conveying guide strip b35 is installed above the single-ear conveying support plate b34.

[0098] Example 7:

[0099] Based on embodiment 5 or 6, a plurality of single ear position sensors b71 are installed on one side of the single ear delivery frame b3. The height of the single ear position sensor b71 matches the height of the single ear b6. The single ear position sensor b71 is used to detect whether a single ear b6 is placed on the single ear storage rack b5.

[0100] In this embodiment, when the single ear position sensor b71 detects that there is no single ear b6 on the single ear storage rack b5, the control system reminds the staff to replenish the single ear b6 on the single ear storage rack b5 in a timely manner.

[0101] Furthermore, a single ear detection reader b74 is installed on one side of the single ear delivery frame b3, and a single ear storage rack b55 is provided on one side of the single ear storage rack b5. The position of the single ear storage rack b55 matches the position between the transmitting end and the receiving end of the single ear detection reader b74.

[0102] In this embodiment, the single-ear detection reader b74 is used to count the number of single-ear storage racks b5. When the single-ear storage rack b55 on the single-ear storage rack b5 passes between the transmitter and receiver of the single-ear detection reader b74, it blocks the signal transmitted from the transmitter to the receiver. At this time, the single-ear detection reader b74 counts a number. The control system calculates the number of supplied single earbuds b6 by using the number of single-ear storage racks b5 recorded by the single-ear detection reader b74.

[0103] Furthermore, a single ear zero-position sensor b72 is installed on one side of the single ear delivery frame b3, and a single ear zero-position detection piece b73 matching the position of the single ear zero-position sensor b72 is installed on one of the single ear storage racks b5.

[0104] In this embodiment, when the single-ear delivery device starts working, the operator places the first single ear b6 on the single-ear storage rack b5 equipped with the single-ear zero-position detection chip b73, and then adds single ears b6 to subsequent single-ear storage racks b5 one after another. When the single-ear storage rack b5 equipped with the single-ear zero-position detection chip b73 passes the single-ear zero-position sensor b72, the single-ear zero-position sensor b72 sends a signal to the control system, and the control system controls the single-ear detection reading head b74 to start counting. In this way, the number of single-ear storage racks b5 without single ears b6 can be avoided, thereby improving the counting accuracy of the single-ear detection reading head b74.

[0105] Example 8:

[0106] Based on Example 1, referring to Figures 15 to 20As shown, the sleeve seat conveying device 10 includes a sleeve seat conveying base 11, with a sleeve seat conveying motor 12 installed at one end of the sleeve seat conveying base 11; a sleeve seat support frame 13 is installed above the sleeve seat conveying base 11, and a sleeve seat rotary conveying device is installed on the sleeve seat support frame 13. Several sleeve seat storage racks 15 are installed on the sleeve seat rotary conveying device, and the sleeve seat storage racks 15 are used to store sleeve seats 16. Several sleeve seat support shafts 153 with lengths matching the width of the sleeve seats 16 are provided between the two side plates of the sleeve seat storage rack 15. The sleeve seats 16 are mounted above the sleeve seat support shafts 153 and placed on the sleeve. The axes of the sleeve I161 and sleeve II162 on the storage rack 15 are parallel to the axis of the sleeve support shaft 153. The two side plates of the sleeve storage rack 15 are respectively provided with arc grooves I151 and II152 that match the inner tubes of the sleeve I161 and sleeve II162. The sleeve conveying motor 12 is connected to the sleeve rotary conveying device. The sleeve conveying motor 12 drives the sleeve rotary conveying device to rotate. The sleeve rotary conveying device drives the sleeve storage rack 15 on it to rotate. The sleeve 16 placed on the sleeve storage rack 15 is continuously supplied with material to the aluminum cantilever production line.

[0107] In this embodiment, the sleeve seat conveying base 11 supports the entire conveying device, and the sleeve seat conveying motor 12 provides power to the sleeve seat rotary conveying device. When the sleeve seat conveying device is working, the operator places the sleeve seat 16 on the sleeve seat storage rack 15. The sleeve seat conveying motor 12 drives the sleeve seat rotary conveying device to rotate, so as to convey the sleeve seat 16 to the target position. Then, the feeding pusher device 40 fixes and grabs the sleeve seat 16 and transfers it to the assembly workbench 60, thereby realizing the continuous supply of sleeve seat 16 in the aluminum cantilever production line.

[0108] like Figure 20 As shown, the sleeve seat 16 includes sleeve I 161, sleeve II 162 and connecting part 163 in the sleeve seat. The difficulty in automating the conveying of the sleeve seat with the aforementioned specific shape is that sleeve I 161 and sleeve II 162 are both cylindrical, which is not easy to place stably. They inevitably move during the conveying process, resulting in uncertainty in the placement of the sleeve seat 16 after it is conveyed to the target position, or even the sleeve seat 16 may not reach the target position. While taking into account the placement stability of the sleeve seat 16, it is also necessary to facilitate the gripping of the feeding pusher device 40 so as to transfer it to the assembly workbench 60.

[0109] Therefore, in this embodiment, the cross-section of the sleeve storage rack 15 is U-shaped, and a plurality of sleeve support shafts 153 are provided between the two side plates. The axis of the sleeve support shaft 153 is parallel to the axis of sleeve I161 and sleeve II162. After the sleeve seat 16 is placed on the sleeve seat storage rack 15, the sleeve seat 16 is positioned between the two side plates of the U-shaped sleeve seat storage rack 15. The sleeve I 161 and sleeve II 162 are respectively mounted between the two sleeve seat support shafts 153. The two side plates of the sleeve seat storage rack 15 limit the left and right positions of the sleeve seat 16. The two sleeve seat support shafts 153 support the sleeve I 161 and limit its front and rear positions. The other two sleeve seat support shafts 153 support the sleeve II 162 and limit its front and rear positions. The other sleeve seat support shafts 153 support the connecting part 163 in the sleeve seat. This ensures that the sleeve seat 16 is stably placed on the sleeve seat storage rack 15. When the sleeve seat storage rack 15 rotates under the drive of the sleeve seat rotary conveyor, the sleeve seat 16 will not shift its position. The sleeve seat support shaft 153 can both support the sleeve seat 16 and effectively avoid the position of the fastening bolts on the sleeve seat 16. Furthermore, the sleeve seat support shaft 153 also corrects the placement orientation of the sleeve seat 16. Specifically, there is a sleeve seat support shaft I151a on each of the lower left and right sides of the arc groove I151 of the sleeve seat storage rack; there is a sleeve seat support shaft I151b on each of the lower left and right sides of the arc groove I152 of the sleeve seat storage rack; in addition, there is a sleeve seat support shaft I151c directly below the arc groove I152 of the sleeve seat storage rack; and there is a sleeve seat support shaft I151d between the arc groove I151 and the arc groove I152 of the sleeve seat storage rack, positioned higher than the other sleeve seat support shafts I151. The sleeve seat 16 is positioned as follows... Figure 20 After being placed on the sleeve holder storage rack 15 in the indicated direction, sleeve I161 is positioned between the two sleeve holder support shafts I151a, just avoiding the position of the fastening bolt below sleeve I161. Sleeve II162 is positioned between the sleeve holder support shafts I151b. The connecting part 163 in the sleeve holder is positioned on the sleeve holder support shaft I151d. A fastening bolt is located above sleeve II162, so it does not interfere with the sleeve holder support shaft I151c. A fastening bolt is located on the connecting part 163 in the sleeve holder, and the end of the fastening bolt that mates with the nut faces upwards. Figure 20The placement direction shown is the correct placement direction. If the placement direction of the sleeve seat 16 is incorrect, it will cause the fastening bolt on the sleeve II 162 to face downwards and interfere with the sleeve seat support shaft I 151c, or cause the sleeve I 161 to be placed on the sleeve seat support shaft I 151b, causing the fastening bolt on it to interfere with the sleeve seat support shaft I 151c, or cause the screw and nut mating end of the fastening bolt on the connecting part 163 of the sleeve seat to face downwards and interfere with the sleeve seat support shaft I 151d. Therefore, the structure of the sleeve seat storage rack 15 has the function of correcting the placement direction of the sleeve seat 16, which can prevent the sleeve seat 16 from being placed in the wrong direction, thereby avoiding affecting subsequent use. The arc grooves I151 and II152 of the sleeve seat storage rack are designed to facilitate the feeding pusher device 40 to extend from one side of the sleeve seat 16 into the inner tubes of sleeve I161 and sleeve II162 to fix and grip the sleeve seat 16 when the sleeve seat 16 moves to the target position, thereby facilitating the automated feeding of the sleeve seat 16.

[0110] This embodiment achieves rotary supply and replenishment of sleeve seats with specific structures by setting up a sleeve seat storage rack with a special structure. This solves the problem in the prior art that the lack of a dedicated storage rack for sleeve seats makes it impossible to achieve automated supply and replenishment of sleeve seats, thus providing technical support for the automated production of aluminum cantilever arms.

[0111] Furthermore, the two sleeve seat support shafts 153 are of equal height and the perpendicular plane of the line connecting their axes passes through the axis of the sleeve I161, and / or the two sleeve seat support shafts 153 are of equal height and the perpendicular plane of the line connecting their axes passes through the axis of the sleeve II162.

[0112] In this embodiment, after the sleeve I161 is placed on the two sleeve seat support shafts 153, its axis falls exactly in the middle of the two sleeve seat support shafts 153, and the heights of the sleeve seat support shafts 153 on both sides of the sleeve I161 are equal, which can better prevent the sleeve I161 from swaying back and forth and make the placement more stable. The arrangement of the sleeve seat support shafts 153 has the same effect on the sleeve II162 as described above on the sleeve I161, and will not be repeated here.

[0113] Furthermore, the arc edge of the arc groove I151 of the sleeve seat storage rack is located between the inner and outer diameters of the sleeve I161, and the arc edge of the arc groove II152 of the sleeve seat is located between the inner and outer diameters of the sleeve II162. This arrangement fulfills the requirement of the feeding pusher device 40 to fix and grip the inner tube of the sleeve seat 16 from the side, while also allowing the two side plates of the sleeve seat storage rack 15 to limit the left and right sides of the sleeve seat 16, preventing lateral movement of the sleeve seat 16.

[0114] Furthermore, the sleeve seat rotary conveying device includes a sleeve seat conveying drive shaft 147 and a sleeve seat conveying driven shaft 148 respectively installed at both ends of the sleeve seat support frame 13. The sleeve seat conveying drive shaft 147 is equipped with sleeve seat conveying drive sprockets 144 at both ends, and the sleeve seat conveying driven shaft 148 is equipped with sleeve seat conveying driven sprockets 145 at both ends. The sleeve seat conveying drive sprockets 144 and the sleeve seat conveying driven sprockets 145 located on the same side of the sleeve seat support frame 13 are connected by a sleeve seat conveying transmission chain 146. The sleeve seat conveying motor 12 is connected to the sleeve seat conveying drive shaft 147, and the two ends of the sleeve seat storage rack 15 are respectively installed on the two sleeve seat conveying transmission chains 146.

[0115] Furthermore, a sleeve seat transmission chain side bracket is provided on one side of the sleeve seat conveying transmission chain 146, and the two ends of the sleeve seat storage rack 15 are respectively fixedly connected to the sleeve seat transmission chain side bracket.

[0116] Furthermore, the casing seat support frame 13 includes casing seat support side plates I131 and II132 located on both sides, and the casing seat support side plates I131 and II132 are fixedly connected by a plurality of casing seat frame support shafts 133.

[0117] In this embodiment, the sleeve seat support frame 13 adopts a structure of two side plates plus a support shaft, which can reduce the weight of the frame and save the frame material while ensuring the support stability of the frame. At the same time, it can avoid the position of the sleeve seat rotary conveyor, making the structure of the whole device more compact.

[0118] Furthermore, the output end of the sleeve seat conveying motor 12 is connected to the sleeve seat motor drive sprocket 141, and one end of the sleeve seat conveying drive shaft 147 is connected to the sleeve seat motor driven sprocket 142. The sleeve seat motor drive sprocket 141 and the sleeve seat motor driven sprocket 142 are connected through the sleeve seat motor transmission chain 143.

[0119] In this embodiment, the output shaft of the sleeve seat conveying motor 12 rotates, driving the sleeve seat motor drive sprocket 141 to rotate. Then, the sleeve seat motor driven sprocket 142 rotates through the sleeve seat motor transmission chain 143, thereby driving the sleeve seat conveying drive shaft 147 to rotate. This causes the sleeve seat conveying drive sprockets 144 installed at both ends of the sleeve seat conveying drive shaft 147 to rotate. Then, the sleeve seat conveying driven sprocket 145 rotates through the sleeve seat conveying transmission chain 146, thereby achieving continuous and stable rotation of the sleeve seat conveying transmission chain 146, and continuously conveying the sleeve seat 16 located above the sleeve seat conveying transmission chain 146 to the target position.

[0120] Furthermore, the sleeve seat conveyor motor 12 is a right-angle output motor. A right-angle output motor saves more front and rear space in the entire device, making the overall structure more compact and reducing the footprint of the entire device, thereby saving space in the entire production line.

[0121] Furthermore, a sleeve seat motor mounting plate 111 is provided on one side of the sleeve seat conveying base 11, and the sleeve seat conveying motor 12 is mounted on the sleeve seat motor mounting plate 111.

[0122] Furthermore, refer to Figure 18 As shown, a sleeve seat conveying guide bar 135 is installed on the sleeve seat support frame 13 below the sleeve seat conveying transmission chain 146. The upper end of the sleeve seat conveying guide bar 135 is provided with a boss. The boss is placed between the inner side plates of the sleeve seat transmission chain on both sides of the sleeve seat conveying transmission chain 146, and the width of the boss matches the length of the sleeve seat transmission chain central axis of the sleeve seat conveying transmission chain 146.

[0123] In this embodiment, the sleeve seat conveying guide bar 135 serves two purposes. First, it supports the bottom of the sleeve seat conveying transmission chain 146, preventing it from bending and deforming due to the weight of the sleeve seat storage rack 15 and the sleeve seat 16. This avoids affecting the service life of the sleeve seat conveying transmission chain 146 and the accuracy of the sleeve seat rotation conveying. Second, the boss is positioned between the inner side plates of the sleeve seat transmission chain on both sides of the sleeve seat conveying chain 146, and the width of the boss matches the length of the sleeve seat transmission shaft. This allows the boss to guide the movement of the sleeve seat conveying transmission chain 146, preventing it from swaying or shifting during movement, thus making the rotation conveying of the sleeve seat more stable and smooth.

[0124] Furthermore, a sleeve seat conveying support plate 134 is installed between the two side plates of the sleeve seat support frame 13, and the sleeve seat conveying guide strip 135 is installed above the sleeve seat conveying support plate 134.

[0125] Furthermore, the sleeve seat support frame 13 is provided with a sleeve seat position detection device. The sleeve seat position detection device includes a plurality of sleeve seat position sensors installed on one side of the sleeve seat support frame 13 and whose height matches that of the sleeve seat 16. The sleeve seat position sensors are used to detect whether a sleeve seat 16 is placed on the sleeve seat storage rack 15.

[0126] In this embodiment, when the sleeve seat position sensor detects that there is no sleeve seat 16 on the sleeve seat storage rack 15, the control system reminds the staff to replenish the sleeve seat 16 on the sleeve seat storage rack 15 in a timely manner.

[0127] Furthermore, the sleeve seat position sensor is a retroreflective photoelectric sensor.

[0128] Furthermore, the sleeve seat position sensor includes a plurality of sleeve seat position sensor transmitters 171 mounted on one side of the sleeve seat support frame 13 and a sleeve seat position sensor reflector 172 mounted on the other side of the sleeve seat support frame 13 and matched with the sleeve seat position sensor transmitters 171.

[0129] Furthermore, a sleeve seat detection reading head 173 is installed on the sleeve seat support frame 13, and a sleeve seat storage rack baffle 154 is provided on one side of the sleeve seat storage rack 15. The position of the sleeve seat storage rack baffle 154 matches the position between the transmitting end and the receiving end of the sleeve seat detection reading head 173.

[0130] In this embodiment, the sleeve seat detection reader 173 is used to count the number of sleeve seat storage racks 15. When the sleeve seat storage rack baffle 154 on the sleeve seat storage rack 15 passes through the sleeve seat detection reader 173 and is located between the transmitting end and the receiving end of the sleeve seat detection reader 173, it blocks the signal transmitted from the transmitting end to the receiving end. The sleeve seat detection reader 173 counts a number. The control system calculates the number of supplied sleeve seats 16 by using the number of sleeve seat storage racks 15 recorded by the sleeve seat detection reader 173.

[0131] Furthermore, a sleeve seat zero-position sensor 174 is installed on the sleeve seat support frame 13, and a sleeve seat zero-position detection piece 175 matching the position of the sleeve seat zero-position sensor 174 is installed on one of the sleeve seat storage racks 15.

[0132] In this embodiment, when the sleeve seat conveying device starts working, the operator places the first sleeve seat 16 on the sleeve seat storage rack 15 equipped with the sleeve seat zero-position detection piece 175, and then adds sleeve seats 16 to the subsequent sleeve seat storage racks 15 one after another. When the sleeve seat storage rack 15 equipped with the sleeve seat zero-position detection piece 175 passes the sleeve seat zero-position sensor 174, the sleeve seat zero-position sensor 174 sends a signal to the control system, and the control system controls the sleeve seat detection reading head 173 to start counting. In this way, the number of sleeve seat storage racks 15 without sleeve seats 16 can be avoided, thereby improving the counting accuracy of the sleeve seat detection reading head 173.

[0133] Example 9:

[0134] Based on any of the foregoing embodiments, refer to Figures 21 to 26As shown, the load-bearing cable seat conveying device includes a load-bearing cable seat conveying base 21, with a load-bearing cable seat conveying motor 22 installed at one end of the load-bearing cable seat conveying base 21; a load-bearing cable seat support frame 23 is installed above the load-bearing cable seat conveying base 21, a load-bearing cable seat rotary conveying device is installed on the load-bearing cable seat support frame, and several load-bearing cable seat storage racks 25 are installed on the load-bearing cable seat rotary conveying device for storing load-bearing cable seats 26. Between the two side plates of the load-bearing cable holder storage rack 25, there are several load-bearing cable holder support shafts with lengths matching the width of the load-bearing cable holder 26. The axis of the load-bearing cable holder support shaft is parallel to the axis of the load-bearing cable holder horizontal tube 261 of the load-bearing cable holder 26. The load-bearing cable holder support shaft includes a load-bearing cable holder horizontal tube support shaft I251, a load-bearing cable holder horizontal tube support shaft II252, a load-bearing cable holder lug support shaft 253, and a load-bearing cable holder vertical tube support shaft 254. After the seat 26 is placed on the load-bearing cable seat storage rack 25, the bottom sides of the load-bearing cable seat horizontal tube 261 of the load-bearing cable seat 26 are respectively attached to the load-bearing cable seat horizontal tube support shaft I251 and the load-bearing cable seat horizontal tube support shaft II252, the load-bearing cable seat lug 262 is attached to the load-bearing cable seat lug support shaft 253, and the load-bearing cable seat vertical tube 263 is attached to the load-bearing cable seat vertical tube support shaft 254. The two side plates of the load-bearing cable seat storage rack 25 are respectively provided with... The load-bearing cable seat storage rack has an arc groove 255 that matches the inner tube of the load-bearing cable seat horizontal tube section 261; the load-bearing cable seat conveying motor 22 is connected to the load-bearing cable seat rotary conveying device, the load-bearing cable seat conveying motor 22 drives the load-bearing cable seat rotary conveying device to rotate, the load-bearing cable seat rotary conveying device drives the load-bearing cable seat storage rack 25 on it to rotate, and the load-bearing cable seats 26 placed on the load-bearing cable seat storage rack 25 are continuously supplied to the aluminum cantilever arm production line.

[0135] In this embodiment, the load-bearing cable seat conveyor base 21 supports the entire conveying device, and the load-bearing cable seat conveyor motor 22 provides power to the load-bearing cable seat rotary conveyor. When the load-bearing cable seat conveyor is working, the operator places the load-bearing cable seat 26 on the load-bearing cable seat storage rack 25. The load-bearing cable seat conveyor motor 22 drives the load-bearing cable seat rotary conveyor to rotate, so as to transport the load-bearing cable seat 26 to the target position. Then, the loading pusher device 40 fixes and grabs the load-bearing cable seat 26 and moves it to the assembly workbench 60, thereby realizing the continuous supply and replenishment of load-bearing cable seats in the aluminum cantilever arm production line.

[0136] like Figure 26As shown, the load-bearing cable seat 26 includes a horizontal tube portion 261, a lug portion 262, a vertical tube portion 263, a locking portion 264, and a cable clamp 265. The difficulty in automating the conveying of a load-bearing cable seat with the aforementioned specific shape lies in the directional requirements of its placement on the conveying device. The locking portion 264 must be placed upwards to cooperate with the gripping action of the subsequent feeding pusher device 40. Furthermore, the horizontal tube portion 261 and the vertical tube portion 263 are perpendicular to each other and both are circular tubes. The shape of the load-bearing cable seat vertical tube 263 and the other end of the load-bearing cable seat vertical tube 263 are also provided with load-bearing cable seat support clamp 265, which causes the weight distribution on both sides of the load-bearing cable seat horizontal tube 261 to be unbalanced and tend to tilt towards the load-bearing cable seat support clamp 265. These structural features are not conducive to stable placement and inevitably cause movement during the transportation process. This results in uncertainty in the placement position of the load-bearing cable seat 26 after it is transported to the target position, or even the inability to reach the target position. While taking into account the placement stability of the load-bearing cable seat 26, it is also necessary to facilitate the gripping of the feeding pusher device 40 so as to transfer it to the assembly workbench 60.

[0137] Therefore, in this embodiment, the cross-section of the load-bearing cable storage rack 25 is U-shaped, and several load-bearing cable support shafts are provided between the two side plates. After the load-bearing cable 26 is placed on the load-bearing cable storage rack 25, it is placed between its two side plates. The two side plates of the load-bearing cable storage rack 25 limit the left and right positions of the load-bearing cable 26 to prevent the load-bearing cable 26 from swaying left and right during the transportation process. The bottom sides of the horizontal tube section 261 of the load-bearing cable seat overlap with the horizontal tube support shaft I251 and the horizontal tube support shaft II252 of the load-bearing cable seat, respectively. The lug section 262 of the load-bearing cable seat overlaps with the lug support shaft 253 of the load-bearing cable seat. The vertical tube section 263 of the load-bearing cable seat overlaps with the vertical tube support shaft 254 of the load-bearing cable seat. The horizontal tube support shaft I251 and the horizontal tube support shaft II252 of the load-bearing cable seat limit the front and rear positions of the horizontal tube section 261 of the load-bearing cable seat, preventing the front of the load-bearing cable seat 26 from... After repositioning, the support shaft 253 for the lug of the load-bearing cable seat and the support shaft 254 for the vertical tube of the load-bearing cable seat support the lug portion 262 and the vertical tube portion 263 of the load-bearing cable seat, respectively. This ensures that both sides of the horizontal tube portion 261 of the load-bearing cable seat are well supported, preventing the load-bearing cable seat 26 from tilting. This allows the load-bearing cable seat 26 to be stably placed on the load-bearing cable seat storage rack 25. Even when the storage rack 25 rotates under the drive of the rotary conveyor, the position of the load-bearing cable seat 26 will not shift. The arc groove 255 of the storage rack facilitates the feeding pusher device 40 extending from one side of the load-bearing cable seat 26 into the inner tube of the horizontal tube portion 261 to secure and grip the load-bearing cable seat 26 when it is moved to the target position, thus achieving automated feeding of the load-bearing cable seat 26. The support shaft on the load-bearing cable holder storage rack 25 has a corrective effect on the placement orientation of the load-bearing cable holder 26. Specifically, for example... Figure 25 and Figure 26 As shown, a fastening bolt is provided above the horizontal tube section 261 of the load-bearing cable seat. A horizontal tube support shaft III is also provided on the load-bearing cable seat storage rack 25, located below the horizontal tube support shaft I251 and the horizontal tube support shaft II of the load-bearing cable seat. If the load-bearing cable seat 26 is arranged as shown... Figure 25 and Figure 26 If the direction shown is correct, then it is the correct orientation. Otherwise, the fastening bolts on the horizontal tube 261 of the load-bearing seat will interfere with the support shaft III of the horizontal tube of the load-bearing cable seat. Therefore, the support shaft on the load-bearing cable seat storage rack 25 also has the function of correcting the placement orientation of the load-bearing cable seat 26, so as to avoid the incorrect placement orientation of the load-bearing cable seat 26 and thus avoid affecting subsequent use.

[0138] This embodiment achieves rotary supply and replenishment of load-bearing cable seats with specific structures by setting up a specially structured storage rack. This solves the problem in the prior art that the lack of a dedicated storage rack for load-bearing cable seats prevents the automated supply and replenishment of load-bearing cable seats, thus providing technical support for the automated production of aluminum cantilever arms.

[0139] Furthermore, the heights of the horizontal tube support shaft I251 and the horizontal tube support shaft II252 of the load-bearing cable seat are equal, and the perpendicular plane of the line connecting their axes passes through the axis of the horizontal tube portion 261 of the load-bearing cable seat.

[0140] In this embodiment, after the load-bearing cable seat 26 is placed on the load-bearing cable seat horizontal tube support shaft I251 and the load-bearing cable seat horizontal tube support shaft II252, the axis of the load-bearing cable seat horizontal tube part 261 falls exactly in the middle of the axis of the load-bearing cable seat horizontal tube support shaft I251 and the load-bearing cable seat horizontal tube support shaft II252, and the heights of the load-bearing cable seat horizontal tube support shaft I251 and the load-bearing cable seat horizontal tube support shaft II252 are equal, which can better prevent the load-bearing cable seat 26 from swaying back and forth, and make the placement more stable.

[0141] Furthermore, the arc edge of the arc groove 255 of the load-bearing cable holder storage rack is located between the inner and outer diameters of the horizontal tube section 261 of the load-bearing cable holder. This arrangement not only fulfills the requirement of the feeding pusher device 40 to fix and grip the inner tube of the horizontal tube section 261 of the load-bearing cable holder from the side, but also ensures that the two side plates of the load-bearing cable holder storage rack 25 limit the left and right sides of the load-bearing cable holder 26, preventing the load-bearing cable holder 26 from moving left and right.

[0142] Furthermore, after the load-bearing cable seat 26 is placed on the load-bearing cable seat storage rack 25, the axis of the load-bearing cable seat vertical tube 263 is in the horizontal plane.

[0143] Furthermore, refer to Figure 22 As shown, the load-bearing cable seat rotary conveying device includes a load-bearing cable seat conveying drive shaft 247 and a load-bearing cable seat conveying driven shaft 248 respectively installed at both ends of the load-bearing cable seat support frame 23. Load-bearing cable seat conveying drive sprockets 244 are respectively installed at both ends of the load-bearing cable seat conveying drive shaft 247, and load-bearing cable seat conveying driven sprockets 245 are respectively installed at both ends of the load-bearing cable seat conveying driven shaft 248. The load-bearing cable seat conveying drive sprockets 244 and load-bearing cable seat conveying driven sprockets 245 located on the same side of the load-bearing cable seat support frame 23 are connected by a load-bearing cable seat conveying transmission chain 246. The two ends of the load-bearing cable seat storage rack 25 are respectively installed on the two load-bearing cable seat conveying transmission chains 246.

[0144] Furthermore, a support bracket for the load-bearing cable seat transmission chain 246 is provided on one side, and the two ends of the load-bearing cable seat storage rack 25 are respectively fixedly connected to the support bracket for the load-bearing cable seat transmission chain.

[0145] Furthermore, the load-bearing cable support frame 23 includes load-bearing cable support side plates I231 and II232 located on both sides, and the load-bearing cable support side plates I231 and II232 are fixedly connected by a plurality of load-bearing cable frame support shafts 233.

[0146] In this embodiment, the load-bearing cable support frame 23 adopts a structure of two side plates and a support shaft, which can reduce the weight of the frame and save the frame material while ensuring the support stability of the frame. At the same time, it can avoid the position of the load-bearing cable rotary conveyor, making the structure of the entire device more compact.

[0147] Furthermore, the output end of the load-bearing cable seat conveyor motor 22 is connected to the load-bearing cable seat drive sprocket 241, and one end of the load-bearing cable seat conveyor drive shaft 247 is connected to the load-bearing cable seat drive driven sprocket 242. The load-bearing cable seat drive sprocket 241 and the load-bearing cable seat drive driven sprocket 242 are connected through the load-bearing cable seat drive transmission chain 243.

[0148] In this embodiment, the output shaft of the load-bearing cable seat conveyor motor 22 rotates, driving the load-bearing cable seat drive sprocket 241 to rotate. Then, the load-bearing cable seat drive driven sprocket 242 rotates through the load-bearing cable seat drive transmission chain 243, thereby driving the load-bearing cable seat conveyor drive shaft 247 to rotate. This causes the load-bearing cable seat conveyor drive sprockets 244 installed at both ends of the load-bearing cable seat conveyor drive shaft 247 to rotate. Then, the load-bearing cable seat conveyor driven sprocket 245 rotates through the load-bearing cable seat conveyor transmission chain 246, thereby achieving continuous and stable rotation of the load-bearing cable seat conveyor transmission chain 246, and continuously conveying the load-bearing cable seat 26 located above the load-bearing cable seat conveyor transmission chain 246 to the target position.

[0149] Furthermore, the load-bearing cable seat conveyor motor 22 is a right-angle output motor. A right-angle output motor saves more front and rear space in the entire device, making the overall structure more compact and reducing the footprint of the entire device, thereby saving the footprint of the entire production line.

[0150] Furthermore, a load-bearing cable seat conveying base 21 is provided on one side of a load-bearing cable seat motor mounting plate 211, and the load-bearing cable seat conveying motor 22 is mounted on the load-bearing cable seat motor mounting plate 211.

[0151] Furthermore, refer to Figure 11As shown, a load-bearing cable support frame 23 is provided with a load-bearing cable conveying guide bar 235 below the load-bearing cable conveying transmission chain 246. The upper surface of the load-bearing cable conveying guide bar 235 is provided with a boss. The boss is placed between the inner side plates of the load-bearing cable transmission chain on both sides of the load-bearing cable transmission chain 246, and the width of the boss matches the length of the central shaft of the load-bearing cable transmission chain 246.

[0152] In this embodiment, the guide bar 235 for the load-bearing cable seat serves two purposes. First, it supports the bottom of the load-bearing cable seat conveyor chain 246, preventing it from bending and deforming due to the weight of the load-bearing cable seat storage rack 25 and the load-bearing cable seat 26. This avoids affecting the service life of the load-bearing cable seat conveyor chain 246 and the accuracy of the load-bearing cable seat rotation. Second, the boss is positioned between the inner plates of the load-bearing cable seat conveyor chain on both sides of the load-bearing cable seat conveyor chain 246, and the width of the boss matches the length of the central axis of the load-bearing cable seat conveyor chain. This allows the boss to guide the movement of the load-bearing cable seat conveyor chain 246, preventing it from swaying or shifting during movement, thus making the rotation of the load-bearing cable seat 26 smoother and more stable.

[0153] Furthermore, a load-bearing cable support frame 23 is installed between the two side plates of the load-bearing cable support frame 23, and a load-bearing cable support conveying guide strip 235 is installed above the load-bearing cable support conveying bracket 234.

[0154] Furthermore, the load-bearing cable support frame 23 is provided with a load-bearing cable position detection device. The load-bearing cable position detection device includes a plurality of load-bearing cable position sensors installed on one side of the load-bearing cable support frame 23 and whose height matches that of the load-bearing cable 26. The load-bearing cable position sensors are used to detect whether a load-bearing cable 26 is placed on the load-bearing cable storage rack 25.

[0155] In this embodiment, when the load-bearing cable seat position sensor detects that there is no load-bearing cable seat 26 on the load-bearing cable seat storage rack 25, the control system reminds the staff to replenish the load-bearing cable seat 26 on the load-bearing cable seat storage rack 25 in a timely manner.

[0156] Furthermore, the load-bearing cable seat position sensor is a retroreflective photoelectric sensor.

[0157] Furthermore, the load-bearing cable seat position sensor includes a plurality of load-bearing cable seat position sensor transmitters 271 installed on one side of the load-bearing cable seat support frame 23 and a load-bearing cable seat position sensor reflector 272 installed on the other side of the load-bearing cable seat support frame 23 and matched with the load-bearing cable seat position sensor transmitters 271.

[0158] Furthermore, a load-bearing cable support frame 23 is installed on the load-bearing cable support frame 23, and a load-bearing cable support storage rack protrusion 256 is installed on one side of the load-bearing cable support storage rack 25. The position of the load-bearing cable support storage rack protrusion 256 matches the position between the transmitting end and the receiving end of the load-bearing cable support detection head 273.

[0159] In this embodiment, the load-bearing cable seat detection head 273 is used to count the number of load-bearing cable seat storage racks 25. When the load-bearing cable seat storage rack protrusion 256 on the load-bearing cable seat storage rack 25 passes between the transmitting end and the receiving end of the load-bearing cable seat detection head 273, it blocks the signal transmitted from the transmitting end to the receiving end. At this time, the load-bearing cable seat detection head 273 counts a quantity. The control system calculates the number of supplied load-bearing cable seats 26 by using the number of load-bearing cable seat storage racks 25 recorded by the load-bearing cable seat detection head 273.

[0160] Furthermore, a zero-position sensor 274 for the load-bearing cable seat is installed on the load-bearing cable seat support frame 23, and a zero-position detection piece 275 for the load-bearing cable seat that matches the position of the zero-position sensor 274 is installed on one of the load-bearing cable seat storage racks 25.

[0161] In this embodiment, when the load-bearing cable conveying device starts working, the operator places the first load-bearing cable 26 on the load-bearing cable storage rack 25 equipped with the load-bearing cable zero-position detection plate 275, and then adds load-bearing cable 26 to subsequent load-bearing cable storage racks 25 one after another. When the load-bearing cable storage rack 25 equipped with the load-bearing cable zero-position detection plate 275 passes the load-bearing cable zero-position sensor 274, the load-bearing cable zero-position sensor 274 sends a signal to the control system, and the control system controls the load-bearing cable detection reading head 273 to start counting. In this way, the number of load-bearing cable storage racks 25 without load-bearing cable 26 can be avoided, thereby improving the counting accuracy of the load-bearing cable detection reading head 273.

[0179] Example 11:

[0180] Based on any of the foregoing embodiments, refer to Figure 28As shown, the feeding pusher device 40 includes a guide cone clamping device, a feeding gripping device, and a feeding drive device mounted on the bottom support plate 47 of the feeding pusher. The front and rear positions of the guide cone clamping device and the feeding gripping device are adjustable. The guide cone clamping device includes a guide cone claw drive device and guide cone claws 415 symmetrically arranged at the lower end of the guide cone drive device. The guide cone drive device drives the guide cone claws 415 to move relative to each other or back to back to clamp and release the guide cone 49. The height of the guide cone claws 415 is adjustable. The feeding gripping device includes a sleeve seat gripper frame 431. Above the sleeve seat gripper frame 431... Two sets of sleeve seat clamping parts are installed side by side on one side. The sleeve seat clamping parts are used to grip and release the sleeve seat 16 and the load-bearing cable seat 26. The sleeve seat clamping parts include a sleeve seat claw driving device and a plurality of sleeve seat claws 438 installed on one side of the sleeve seat claw driving device. The sleeve seat claw driving device drives the sleeve seat claws 438 to move relative to each other or back to back. The height of the sleeve seat clamping parts is adjustable, the sleeve seat clamping parts can be flipped left and right, and the sleeve seat clamping parts can rotate around the sleeve seat gripper lifting frame in the horizontal plane. The feeding driving device is used to drive the feeding push head bottom support plate 47 to move left and right.

[0181] In this embodiment, refer to Figure 14 As shown, the process of loading the sleeve seat 16 and the load-bearing cable seat 26 onto the assembly workbench 60 is as follows: the loading drive device drives the loading push head device 40 to move to one side of the sleeve seat conveying device 10 or the load-bearing cable seat conveying device 20. The sleeve seat gripper 438 rotates in the horizontal plane to the front side of the sleeve seat gripper lifting frame 433. Then, under the drive of the loading drive device, it moves left and right so that the two sets of sleeve seat grippers 438 extend into the sleeve I161 and sleeve II162 of the sleeve seat conveying device 10 respectively, or so that one set of sleeve seat grippers 438 extends into the load-bearing cable seat horizontal tube 261 of the load-bearing cable seat 20. Then, under the drive of the sleeve seat gripper drive device, the sleeve seat grippers 438 move back and forth to clamp and fix the sleeve seat 16 or the load-bearing cable seat 26. The feeding drive device drives the feeding pusher device 40 to move to the vicinity of the assembly table sleeve seat storage rack 67 or the assembly table load-bearing cable seat storage rack 65 on the assembly worktable 60. Before this, the sleeve seat gripper 438 first rotates in the horizontal plane to the rear side of the sleeve seat gripper lifting frame 433. At the same time, the height of the guide cone gripper 415 and the sleeve seat clamping part are both raised to avoid interference with other parts during the movement. Then, by adjusting the height, left and right position and front and back position of the sleeve seat clamping part, the sleeve seat 16 is placed on the assembly table sleeve seat storage rack 67 or the load-bearing cable seat 26 is placed near the assembly table load-bearing cable seat storage rack 65.

[0182] The process of installing the guide cone 49 at the end of the flat or inclined arm is as follows: In the initial state, the guide cone gripper 415 holds the guide cone 49.

Then, the guide cone gripper moves to the right to insert the guide cone 49 into the left port of the flat or inclined arm. Then, the guide cone gripper drive device drives the guide cone gripper 415 to move in opposite directions to release the guide cone 49, and the guide cone 49 stays in the left port of the flat or inclined arm. Similarly, when removing the guide cone 49 from the end of the flat or angled arm, the feeding drive device drives the feeding pusher device 40 to move to the left end of the flat or angled arm, and adjusts the front-to-back position and height of the guide cone clamping device so that the guide cone 49 is just inside the guide cone jaw 415. The guide cone jaw drive device drives the guide cone jaw 415 to move relative to clamp the guide cone 49, and then moves the guide cone clamping device to the left to remove the guide cone 49 from the left end of the flat or angled arm. The guide cone clamping device makes it easier for the flat or angled arm with the guide cone 49 installed to be inserted into the inner tube of the sleeve seat and the load-bearing cable seat.

[0183] This embodiment achieves automatic feeding of the sleeve seat 16 and the load-bearing cable seat 26, and realizes the guide cone 49
