Description

Technical Field

[0001] The present application relates to the technical field of seat pulley assembly, and in particular to a seat pulley assembly device. Background Art

[0002] A chair is a common daily necessity in daily life. There are many types of existing chairs. In some office situations, in order to facilitate the movement of the chair, pulleys are installed at the bottom of the chair, and the pulleys are used to make the movement convenient and quick.

[0003] The seat pulley comprises a wheel body, a left wheel and a right wheel installed on the wheel body through a pin shaft, and a mounting bolt inserted and installed on the top of the wheel body.

[0004] In the prior art, pulley assembly is generally performed manually in multiple steps, but the quality of manual assembly varies and the efficiency is also low. Therefore, the quality and efficiency of pulley assembly are issues that need to be urgently addressed. Summary of the invention

[0005] In order to improve the quality and efficiency of pulley assembly, the present application provides a seat pulley assembly device.

[0006] The present application provides a seat pulley assembly device, which adopts the following technical solution: A seat pulley assembly device comprises a frame and an assembly device arranged on the frame, wherein the assembly device comprises: A slideway is arranged on the rack; The main track is used to transport the wheel body to the slideway for transportation; A pushing component, used for pushing the wheel body to move; A pin shaft installation mechanism is used to insert and install the pin shaft onto the wheel body; The left and right wheel installation mechanism is used to insert and install the left and right wheels onto the pin shaft; The bolt installation mechanism is used to insert and install the bolts on the wheel body.

[0007] By adopting the above technical solution, the main track transports the wheel body to the slideway, the pushing assembly continuously pushes the wheel body forward, and the wheel body moves one station at a time, so that the wheel body passes through the pin shaft installation mechanism, the left and right wheel installation mechanism, and the bolt installation mechanism in sequence, so that the pin shaft is plugged and installed to the wheel body, the left and right wheels are installed on the pin shaft, and the bolt is plugged and installed on the wheel body, thereby completing the assembly of the entire pulley without manual installation, thereby improving the quality and efficiency of the pulley assembly.

[0008] Optionally, the bolt installation mechanism includes: A loading seat is arranged on the frame and extends above the slideway and is provided with a loading hole; A feeding assembly is used to continuously convey the bolts to the feeding seat and allow the bolts to fall through the feeding holes in sequence and be inserted and installed on the wheel body; The extrusion assembly is used to extrude the bolts and complete the assembly of the bolts and the wheel body.

[0009] By adopting the above technical solution, the loading assembly continuously transports the bolts to the loading seat, and the bolts are inserted and installed on the wheel body under the action of gravity. The wheel body continues to move forward to the extrusion assembly, and the extrusion assembly continues to extrude the bolts, so that the bolts are inserted and installed on the wheel body, thereby improving the efficiency and quality of the bolt assembly process and the quality and efficiency of the pulley assembly.

[0010] Optionally, the feeding assembly includes: A bolt loader is arranged on the frame; The bolt track is arranged on the loading seat and connected to the bolt loading machine in an inclined upward direction. When the bolt loading machine is started, the bolts are neatly arranged and placed on the bolt track; A spring sheet is arranged on the feeding hole and presses against the bolt to prevent the bolt from passing through the feeding hole; The pushing member is used to push the spring piece away from the bolt to achieve unlocking and enable the bolt to be inserted and installed on the wheel body under the action of gravity.

[0011] By adopting the above technical scheme, the bolt loader conveys multiple bolts to the bolt track, so that the multiple bolts are arranged as a whole on the bolt track, and the bolt track is in an inclined state, so that the bolts can be pushed to move toward the loading hole, and the spring sheet is pressed against the lowest bolt for positioning, blocking it from entering the loading hole. When loading is required, the pushing member starts to push the spring sheet and makes the spring sheet away from the bolt. The bolt at the lowest position is installed on the wheel body through the loading hole under the action of gravity, and then the pushing member moves back, and the spring sheet rotates under the action of elastic force to continue to position the bolt, thereby realizing the insertion and installation of the bolt on the wheel body, thereby improving the efficiency and position accuracy of loading, and improving the quality and efficiency of pulley assembly.

[0012] Optionally, when the bolt is inserted and installed on the wheel body, the top is located in the loading hole for guidance. The loading hole is connected to one end of the loading seat so that when the wheel body moves, the bolt is driven out of the loading hole. When the pushing member pushes the spring sheet, it extends downward into the loading hole and is provided with an inclined pushing surface. The pushing surface pushes the bolt downward and makes the bolt rest against the loading hole for guiding and positioning.

[0013] By adopting the above technical solution, the pushing member pushes the spring sheet to rotate to realize the downward drop of the bolt, and the top of the bolt is located in the guide hole for guidance, and the pushing member continues to move so that the pushing surface is pressed against the bolt, thereby pushing the bolt downward and making the bolt rest against the feeding hole. The guide hole is used to guide and position the bolt downward, reducing the probability of the bolt being skewed during extrusion, and also reducing the probability of the extrusion assembly being skewed when extruding the bolt or the bolt falling off during transportation, further improving the quality and efficiency of the pulley assembly.

[0014] Optionally, the extrusion assembly includes: A mounting base, arranged on the frame; An extrusion seat is vertically slidably arranged on the mounting seat and is used for extruding and installing the bolts; The extrusion piece is used to drive the extrusion seat to move.

[0015] By adopting the above technical solution, the extrusion member starts to drive the extrusion seat to move downward to extrude the bolt, so that the bolt is inserted and installed on the wheel body to complete the assembly.

[0016] Optionally, a detection mechanism is provided on the frame, and the detection mechanism includes: A detector, used to detect whether bolts are installed on the wheel body; The material replenishing assembly is electrically connected to the detector. When the detector detects that the bolts are not installed, the material replenishing assembly inserts the bolts into the wheel body and moves the wheel body after the bolts are inserted and installed to the extrusion assembly.

[0017] By adopting the above technical solution, because the bolts are inserted and installed on the wheel body under the action of gravity, the bolts are easily unstable due to the influence of external force during insertion, which may cause the bolts to fall off during the movement of the wheel body, or the bolts may fail to fall off from the loading seat during installation. These will reduce the assembly quality of the pulley, and the assembly efficiency will be reduced if it is reassembled.

[0018] The detector is used to detect whether the bolts are installed on the wheel body. If installed, it moves normally. Otherwise, the wheel body moves to the feeding assembly, and the feeding assembly inserts and installs the bolts on the wheel body. Then the wheel body and the bolts are moved to the extrusion assembly to continue extrusion to complete the final assembly, thereby improving the assembly quality and efficiency of the pulley.

[0019] Optionally, the feeding component comprises: A feeding seat is arranged on the frame and extends above the wheel body and is provided with a feeding channel for the bolts to pass through; A feeding track is arranged on the feeding seat and is arranged obliquely upward and connected to the bolt track. The bolts on the bolt track are moved to the feeding track and placed thereon, and the bolts are pushed to move to the feeding channel. An elastic member presses against the bolt and blocks the bolt from entering the feeding channel; The pushing piece is used to push the bolt located at the feeding channel to squeeze the elastic piece so that the bolt is inserted and installed on the wheel body through the feeding channel. The pushing piece enters the feeding channel to block the subsequent bolts from entering, and after exiting, the elastic piece rebounds and presses against the bolt to position it.

[0020] By adopting the above technical solution, when it is necessary to insert and install the bolt, the pushing piece starts to push the bolt, and the bolt pushes the elastic piece away and moves downward into the feeding channel, and the pushing piece enters the feeding channel to push the bolt to be inserted and installed on the wheel body. The feeding channel guides the bolt when it is squeezed, and makes the bolt move to the bottom of the feeding channel, and then the pushing piece moves up and is pushed out of the feeding channel, and the elastic piece moves back and presses on the bolt to prevent the bolt from entering the feeding channel. Multiple bolts on the feeding track are convenient for subsequent feeding. Therefore, the convenience and quality of bolt installation are improved through the pushing of the pushing piece and the guidance of the feeding channel, and the assembly quality and efficiency of the pulley are improved.

[0021] Optionally, the extrusion seat is located above two adjacent wheel bodies and below the feeding channel, and the extrusion seat is provided with a guide tube whose axis coincides with the feeding channel, and the inner diameter of the guide tube is the same as the inner diameter of the feeding channel.

[0022] By adopting the above technical solution, the guide tube can guide the bolt when it is inserted into the wheel body through the feeding channel, further improving the guiding effect of the bolt, and when the wheel body moves, the extrusion seat drives the guide tube to move upward and disengage from the bolt, so that the wheel body and the bolt can continue to move, thereby further improving the guiding and positioning effect of the bolt, reducing the probability of crooked installation of the bolt, and improving the installation quality of the bolt.

[0023] Moreover, there is no need to add bolts, that is, when the bolts have been installed on the wheel body, the extrusion seat moves downward to drive the guide tube to move downward, so that the bolts enter the guide tube, thereby correcting the skewed bolts. Therefore, the corrected bolts continue to move forward and are extruded and installed through the extrusion seat, thereby improving the installation quality, thereby further improving the assembly quality and efficiency of the pulley.

[0024] Optionally, the pin installation mechanism includes: A pin shaft seat is arranged on the frame and is used to vertically stack and place a plurality of pin shafts; Pin loader, used to continuously transport the pins to the pin seats for placement; The pushing component is used to push out the pin shaft located at the lowest position and insert it into the wheel body.

[0025] By adopting the above technical solution, the pin loader transports the pin to the pin seat for placement, and then the pushing component is started to push the pin located at the lowest point to be plugged and installed on the wheel body, the pushing component is moved back, and the pin moves downward under the action of gravity for replenishment, thereby realizing the installation of the pin.

[0026] Optionally, the left and right wheel mounting mechanism includes: The left wheel track and the right wheel track are arranged on the frame and are arranged upwardly and tilted, and the left wheel track and the right wheel track are respectively used to place the left wheel and the right wheel neatly and to place the left wheel and the right wheel at the lowest position vertically; The driving assembly is used to drive the left wheel and the right wheel to approach each other and to be plugged with the pin shaft to complete the assembly.

[0027] By adopting the above technical solution, the left wheel track and the right wheel track are used to transport the left wheel and the right wheel respectively, and the left wheel and the right wheel at the lowest point are placed vertically, and the driving component starts to drive the left wheel and the right wheel to approach each other, so that the left wheel and the right wheel are simultaneously plugged into the pin shaft, thereby completing the installation of the left wheel and the right wheel, and the left wheel and the right wheel are moved at the same time, so that the forces on both ends of the pin shaft are balanced, the probability of displacement of the pin shaft is reduced, and the quality and efficiency of the pulley assembly are improved.

[0028] In summary, the present application includes at least one of the following beneficial technical effects: The wheel body is transported to the slideway through the main track, and the pushing assembly continuously pushes the wheel body forward, so that the wheel body passes through the pin shaft installation mechanism, the left and right wheel installation mechanism, and the bolt installation mechanism in sequence, so that the pin shaft is plugged and installed to the wheel body, the left and right wheels are installed on the pin shaft, and the bolt is plugged and installed to the wheel body, thereby completing the assembly of the entire pulley without manual installation, thereby improving the quality and efficiency of the pulley assembly.

[0031] The following is combined with Figure 1-5 This application is described in further detail.

[0032] The embodiment of the present application discloses a seat pulley assembly device.

[0033] Example 1 Reference Figure 1 The seat pulley assembly equipment includes a frame 1 and an assembly device 2 arranged on the frame 1. The assembly device 2 is used to assemble the pin shaft, the left wheel and the right wheel, and the bolts to the wheel body in sequence.

[0034] Reference Figure 1 and Figure 2 The assembly device 2 includes a slide 21, a main track 22, a pushing assembly 23, a pin shaft mounting mechanism 3, and a left and right wheel mounting mechanism 4. The slide 21 is fixedly mounted on the upper surface of the frame 1 along the length direction of the frame 1. One end of the main track 22 is fixedly mounted on the frame 1 and is connected to the slide 21, and is used to transport the wheel body to the slide 21 for transportation. At the same time, the main track 22 is tilted upward away from one end of the slide 21 and is connected to the vibrating loading tray. The vibrating loading tray vibrates to transport the wheel body to the main track 22 for transportation. The vibrating loading tray is a prior art and will not be described here.

[0035] The pushing assembly 23 is arranged on the frame 1 and is used to push the wheel body on the slide 21 to move forward. The pushing assembly 23 includes a pushing block 24 and a pushing cylinder 25. The pushing block 24 is slidably installed along the length direction of the slide 21 at the bottom of the main track 22 and the connection between the slide 21. The pushing cylinder 25 is fixed on the frame 1 and connected to the pushing block 24, so as to drive the pushing block 24 to move. The pushing block 24 pushes the wheel body at the connection between the slide 21 and the main track 22 to move forward. The forward movement distance is the distance between the centers of two adjacent wheel bodies, so that the wheel body moves one station, so that the wheel body passes through the pin shaft installation mechanism 3, the left and right wheel installation mechanism 4 and the bolt installation mechanism 5 in sequence; the pushing block 24 moves back, and a wheel body located in the main track 22 falls into the slide 21 for positioning, so as to facilitate the push block 24 to continue to move and push the wheel body forward.

[0036] The pin shaft installation mechanism 3 is used to insert and install the pin shaft onto the wheel body. The pin shaft installation mechanism 3 includes a pin shaft seat 31, a pin shaft loader 32 and a pushing assembly 33. The pin shaft seat 31 is fixedly installed on the frame 1 and is vertically arranged. The pin shaft seat 31 is used to vertically stack multiple pin shafts; the pin shaft loader 32 is a vibrating loading plate, which is connected to the pin shaft seat 31 and is used to continuously transport the pin shaft and place it on the pin shaft seat 31.

[0037] The push assembly 33 is arranged on the frame 1 and is used to plug and install the pin shaft located at the lowest position onto the wheel body. The push assembly 33 includes a push cylinder 34 and a push column 35. The push cylinder 34 is fixedly installed on the frame 1, and the push column 35 is fixedly installed on the piston rod of the push cylinder 34. A pin shaft hole for the push column 35 and the pin shaft to pass through is provided at the bottom of the pin shaft seat 31. The pin shaft located at the lowest position is flush with the plug-in position of the wheel main wheel. At the same time, the distance between the end of the pin shaft close to the wheel body and the wheel body is less than the length of the pin shaft, so that when one end of the pin shaft is plugged and installed on the wheel body, the other end of the pin shaft is also located on the pin shaft hole for positioning, so that the pin shaft plug-in accuracy is higher. The push cylinder 34 is started to drive the push column 35 to move, and the push column 35 moves to push the pin shaft to be plugged and installed on the wheel body through the pin shaft hole, and then the push column 35 moves back, thereby realizing the plug-in installation of the pin shaft on the wheel body.

[0038] The left and right wheel mounting mechanism 4 is used to plug and mount the left and right wheels onto the pin shaft, and the left and right wheel mounting mechanism 4 includes a left wheel track 41, a right wheel track 42, and a driving assembly 43. The left wheel track 41 and the right wheel track 42 are located on both sides of the slide 21 and are arranged in a mirror-symmetrical manner with respect to the slide 21; the left wheel track 41 and the right wheel track 42 have the same structure, the bottom end of the left wheel track 41 is fixedly mounted on the frame 1 and connected to the slide 21, and the top of the left wheel track 41 is inclined upward, and the tops of the left wheel track 41 and the right wheel track 42 are respectively connected to two vibrating loading trays, so as to realize continuous conveying of the left wheel into the left wheel track 41 and continuous conveying of the right wheel into the right wheel track 42, and the left and right wheels located at the lowest point are in a vertical state; a through hole for the left and right wheels to pass through is opened on the slide 21.

[0039] The driving assembly 43 is arranged on the frame 1 and is used to drive the left wheel and the right wheel to approach each other and be plugged into the pin shaft to complete the assembly. Two driving assemblies 43 are arranged and are respectively located on both sides of the slideway 21, and are respectively used to drive the left wheel and the right wheel to move. The driving assembly 43 includes a driving cylinder 44 and a driving block 45. The driving cylinder 44 is fixedly installed on the frame 1, and the driving block 45 is fixedly installed on the piston rod of the driving cylinder 44. The two driving cylinders 44 are started at the same time to drive the two driving blocks 45 to push the left wheel and the right wheel to be plugged into the pin shaft, so that the forces at both ends of the pin shaft are consistent, reducing the probability of displacement of the pin shaft.

[0040] Reference Figure 1 and Figure 3 The assembly device 2 also includes a bolt installation mechanism 5, which is used to insert and install the bolts on the wheel body; the bolt installation mechanism 5 includes a loading seat 51, a loading assembly 6 and an extrusion assembly 7. The loading seat 51 is fixedly installed on the frame 1 and extends above the slideway 21. A loading hole 52 that penetrates the loading seat 51 and is used for the bolt to pass through is opened on the loading seat 51. The loading hole 52 penetrates the loading seat 51 along the length direction of the slideway 21, and a side wall of the loading seat 51 parallel to the length direction of the slideway 21 is provided with an avoidance hole 53 connected to the loading hole 52, and the width of the avoidance hole 53 is smaller than the diameter of the loading hole 52.

[0041] The loading assembly 6 is used to continuously convey the bolts to the loading seat 51 and allow the bolts to fall down in sequence through the loading holes 52 and be installed on the wheel body. The loading assembly 6 includes a bolt loader, a bolt track 61, a spring 62 and a pusher 63. The bolt loader is fixedly installed on the frame 1 and is a vibrating loading plate. The bolt track 61 is fixedly installed on the side wall of the loading seat 51 with the avoidance hole 53 and is connected to the bolt loader with an angle upward. The bolt loader is started to input the bolts into the bolt track 61, so that multiple bolts are neatly arranged and placed on the bolt track 61, and the bolts are pushed into the avoidance hole 53 and the loading hole 52. An annular portion protruding outward is formed on the bolt. When the bolt passes through the avoidance hole 53, the annular portion rests on the upper surface of the loading seat 51 for positioning.

[0042] One end of the spring sheet 62 is fixedly mounted on the side wall of the feeding hole 52, and the other end of the spring sheet 62 extends to the connection between the feeding hole 52 and the avoidance hole 53 and presses on the bolt, and the annular portion is placed on the upper surface of the spring sheet 62 for positioning, thereby blocking the bolt from passing through the feeding hole 52. A support seat 11 extending above the slideway 21 is fixedly mounted on the frame 1, and the support seat 11 is located on the side of the feeding seat 51 away from the left and right wheel mounting mechanisms 4; the pusher 63 is slidably mounted on the support seat 11 along the length direction of the slideway 21, and the pusher 63 extends from the connection between the feeding hole 52 and the feeding seat 51 to the feeding hole 52, and the pusher 63 is used to push the spring sheet 62 to rotate, so that the spring sheet 62 is away from the bolt and the bolt falls downward and is inserted and installed on the wheel body for positioning.

[0043] The extrusion assembly 7 is used to extrude and position the bolts and enable the bolts to be assembled with the wheel body. The extrusion assembly 7 includes a mounting seat 71, an extrusion seat 72 and an extrusion piece 73. The mounting seat 71 is fixedly mounted on the frame 1 and extends above the slideway 21; the extrusion seat 72 is vertically slidably mounted on the top of the mounting seat 71 and extends to the top of the slideway 21. The extrusion piece 73 is a cylinder and is fixedly mounted on the mounting seat 71, and the piston rod of the extrusion piece 73 is connected to the extrusion seat 72, so as to achieve the vertical movement of the extrusion seat 72. After the bolts are plugged and installed on the wheel body, the wheel body and the bolts are moved to the bottom of the extrusion seat 72, and the extrusion piece 73 drives the extrusion seat 72 to move downward to extrude the bolts, so that the bolts and the wheel body are assembled, so as to assemble the pulley. The assembled pulley is transported through the slideway 21 and then collected.

[0044] The working principle of the embodiment of the present application is as follows: The main track 22 transports the wheel body to the slideway 21, and the pushing cylinder 25 starts to push the pushing block 24 to push the wheel body to move. The wheel body moves to the pin shaft seat 31, and the pushing cylinder 34 starts to push the pin shaft to be plugged and installed on the wheel body. The wheel body continues to move to the left wheel track 41 and the right wheel track 42. The two driving cylinders 44 push the left wheel and the right wheel to be plugged and matched with the two ends of the pin shaft. The wheel body moves to the feeding hole 52, and the pushing member 63 pushes the spring piece 62 away from the bolt, and the bolt falls down and is plugged and installed on the wheel body. The pushing member 63 moves back, and the spring piece 62 rebounds to position the bolt. The wheel body continues to move forward to the extrusion seat 72, and the extrusion member 73 drives the extrusion seat 72 to move down and extrude the bolt, so that the bolt and the wheel body are assembled. The assembly of the pulley is completed, thereby completing the assembly of the pulley, improving the quality and efficiency of the pulley assembly.

[0045] Example 2 Reference Figure 1 and Figure 4 The difference between this embodiment and embodiment 1 is that the sliding direction of the pushing member 63 is in an inclined state, and the pushing member 63 pushes the spring sheet 62 away from the bolt and moves it downward in an inclined manner; when the bolt is inserted and installed on the wheel body, the top of the bolt is located in the loading hole 52, and the pushing member 63 is provided with an inclined pushing surface 64 near one end of the bolt. As the pushing member 63 approaches the bolt, the pushing surface 64 gradually pushes the top of the bolt to move downward, and at this time the bolt abuts against the loading hole 52 for guiding and positioning, so that the bolt can be better plugged in with the wheel body, reducing the probability of the bolt falling off the wheel body, and improving the bolt installation position more accurately when the subsequent extrusion assembly 7 extrudes the bolt, thereby improving the quality and efficiency of the pulley assembly.

[0046] The working principle of the embodiment of the present application is as follows: The pushing member 63 pushes the spring piece 62 to rotate away from the bolt, so that the bolt is inserted downward through the loading hole 52 and installed on the wheel body. The pushing member 63 continues to move downward at an angle, and the pushing surface 64 pushes the bolt downward to insert and install the bolt on the wheel body and limit it through the loading hole 52. The pushing member 63 tilts upward away from the bolt and the spring piece 62, and the wheel body drives the bolt to move out through the loading hole 52 to move, so that the bolt can be better inserted and installed on the wheel body, reducing the probability of the bolt falling or tilting, and improving the quality of the pulley assembly.

[0047] Example 3 Reference Figure 1 and Figure 5 The difference between this embodiment and embodiment 1 is that a detection mechanism 8 is provided on the frame 1 and between the support seat 11 and the mounting seat 71. The detection mechanism 8 is used to detect whether the bolts on the wheel body are installed. When the bolts are not installed, the detection mechanism 8 is used to supplement and insert the bolts into the wheel body.

[0048] The detection mechanism 8 includes a detector 81 and a filling assembly 9. The detector 81 is fixedly mounted on the frame 1 and is used to detect whether the bolts are installed on the wheel body. The filling assembly 9 is electrically connected to the detector 81. When the detector 81 detects that the bolts are not installed on the wheel body, the filling assembly 9 inserts and installs the bolts on the wheel body for replenishment. After replenishment, the wheel body with the bolts is moved to the extrusion assembly 7 for re-extrusion and installation.

[0049] The feeding assembly 9 includes a feeding seat 91, a feeding track 92, an elastic member 93 and a pushing member 94. The feeding seat 91 is fixedly mounted on the frame 1 and extends to the top of the slideway 21. The feeding seat 91 is located between the support seat 11 and the mounting seat 71. A feeding channel 95 for the bolts to pass through is provided on the feeding seat 91, and the feeding channel 95 is connected to the side wall of the feeding seat 91; the feeding track 92 is fixedly mounted on the side wall of the feeding seat 91, and the other end of the feeding track 92 is tilted upward and connected to the bolt track 61, so that the bolts can be neatly arranged on the feeding track 92. The elastic member 93 is fixedly mounted on the feeding channel 95, and the elastic member 93 presses on the bolts and blocks the bolts from passing through the feeding channel 95.

[0050] The pusher 94 is vertically slidably arranged on the feeding seat 91 and is located above the feeding channel 95, and the pusher 94 is driven to move by the cylinder. A control component for controlling the start and stop of the cylinder is fixedly installed on the frame 1, and the control component is electrically connected to the detector 81, and the detector 81 transmits the detection signal to the control component; the pusher 94 pushes the bolt to squeeze the elastic component 93, so as to unlock the bolt, and the pusher 63 pushes the bolt downward to be inserted and installed on the wheel body through the feeding channel 95, so as to realize the additional installation of the bolt on the wheel body, and when the pusher 63 enters the feeding channel 95, the pusher 63 can also block the movement of the bolt, and the pusher 63 moves up to the top of the feeding channel 95, the bolt is pushed forward, and the elastic component 93 rebounds and presses on the bolt for positioning. In this way, the bolt is additionally installed on the wheel body, thereby improving the quality and efficiency of the pulley assembly.

[0051] The length of the extrusion seat 72 extends to above the two adjacent wheel bodies. A guide tube 12 is fixedly installed on the lower surface of the extrusion seat 72, and the guide tube 12 is in a vertical state. The guide tube 12 is connected to the upper surface of the extrusion seat 72 and coincides with the axis of the feeding channel 95. At the same time, the inner diameter of the guide tube 12 is the same as the diameter of the feeding channel 95. The feeding seat 91 and the feeding channel 95 are located above the extrusion seat 72, and the guide tube 12 coincides with the axis of the wheel body on the side close to the loading seat 51 of the two adjacent wheel bodies.

[0052] When the bolts are supplementarily inserted and installed on the previous wheel body, the extrusion seat 72 moves downward to extrude and assemble the bolts on the subsequent wheel body. At the same time, the downward movement of the extrusion seat 72 drives the guide tube 12 to move downward, so that the guide tube 12 can guide the bolts when they are installed. Then the extrusion seat 72 drives the guide tube 12 to move upward, so that the bolts are moved out of the guide tube 12, and the wheel body moves forward one station. The extrusion seat 72 moves downward to punch the supplementary bolts to complete the assembly; and when the bolts have been installed on the wheel body, the downward movement of the guide tube 12 can guide and correct the bolts, so that the bolts can be in a vertical state and completed with the wheel body, thereby improving the assembly accuracy and the quality of the pulley assembly.

[0053] The working principle of the embodiment of the present application is as follows: The detector 81 detects whether the bolts are installed on the wheel body. If they are installed, it proceeds normally. If it is detected that they are not installed, the wheel body moves to the bottom of the feeding channel 95, and the pushing piece 94 pushes the bolts through the feeding channel 95 and the guide tube 12 to be installed on the wheel body. The feeding channel 95 and the guide tube 12 are used to guide and limit the bolts. The pushing piece 94 moves up to above the feeding channel 95, and the elastic piece 93 presses on the bolts for positioning. The wheel body continues to move forward, and the extrusion seat 72 moves down to extrude and assemble the bolts, thereby improving the quality of the pulley assembly.

[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
