Abstract
Description
Technical Field
[0001] This invention relates to the field of rack machining technology, specifically to a rack machining apparatus. Background Technology
[0002] A rack is a special type of gear with teeth distributed on a bar-shaped body. The processing of racks usually requires cutting, milling, heat treatment, grinding, straightening and aging, drilling and shaping of the blank. Each process requires a feeding device to feed the rack. Traditional feeding methods can only feed one machine, resulting in low feeding efficiency and a large footprint.
[0003] Chinese patent CN215248076U discloses a rack processing device with a bidirectional feeding mechanism. By adding a bidirectional feeding mechanism, the device can improve the rack processing efficiency. The feeding mechanism can automatically feed the rack, reducing manual labor and lowering labor intensity.
[0004] However, in actual use, since rack processing requires multiple steps, traditional feeding equipment needs to feed the rack during each step and clean the processing debris on the rack surface before feeding. This makes it impossible for the rack to be transferred between processing devices, resulting in a decrease in the rack processing efficiency, which affects the processing efficiency and reduces the automation effect of the equipment. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this invention provides a rack processing device that solves the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a rack processing device, comprising two worktables and guide rails fixed above the two worktables, with connecting trolleys slidably mounted on the guide rails at equal intervals; a chain mounted above the guide rails to drive the connecting trolleys to move on the guide rails; a rack processing machine tool located between the two worktables, the distance between the two rack processing machine tools on the same side being the same as the travel path distance between two adjacent connecting trolleys, so that the rack body is processed synchronously inside different rack processing machine tools; a connecting cylinder fixed to the lower end of the connecting trolley, with a connecting frame fixed to the telescopic end of the connecting cylinder, an electric telescopic cylinder rotatably mounted on the connecting frame, and a fixing fixture provided at the telescopic end of the electric telescopic cylinder for fixing the rack body; and a flipping assembly located on the connecting trolley for flipping the fixing fixture, so that processing debris on the surface of the rack body is shaken off before entering the downstream rack processing machine tool.
[0007] Furthermore, the flipping assembly includes a transmission rack fixed to the outside of the guide rail. The transmission rack is located downstream of each rack processing machine tool. A transmission gear that meshes with the transmission rack is rotatably installed inside the connecting trolley. A telescopic tube fixedly connected to the center of the transmission gear is provided at the lower end of the connecting trolley. The lower end of the telescopic tube rises and falls synchronously with the lower end of the connecting cylinder. A first bevel gear is installed at the lower end of the telescopic tube. A second bevel gear that meshes with the first bevel gear is installed on the electric telescopic cylinder.
[0008] Furthermore, it also includes a loading and unloading assembly, which includes an equipment box fixed at the middle position of the workbench, a first rotating arm rotatably mounted on one side of the upper end of the equipment box, and a second rotating arm rotatably mounted on the other side of the upper end of the equipment box; a lifting cylinder, which is fixed to the ends of the first rotating arm and the second rotating arm away from the equipment box, and a suction cup for gripping the rack body is installed at the telescopic end of the lifting cylinder; and a transmission assembly, which is located inside the equipment box to drive the first rotating arm and the second rotating arm to rotate in the same direction.
[0009] Furthermore, the telescopic tube includes a sleeve fixed to the lower end of the connecting trolley, and a lifting rod is slidably installed inside the sleeve; a connecting plate is fixed to the telescopic end of the connecting cylinder, the lifting rod is rotatably connected to the connecting plate, and the lower end of the lifting rod is fixedly connected to the first bevel gear.
[0010] Furthermore, the fixed fixture includes a tongue plate located at the lower inner end of the connecting frame; a support frame located above the tongue plate, with one side of the support frame fixedly connected to the telescopic end of the electric telescopic cylinder, the upper surface of the support frame having an installation groove for holding the rack body; and a pressure plate installed at both ends inside the installation groove, with clamping cylinders fixed at both ends of the outer side of the support frame for driving the pressure plate to move in opposite directions.
[0011] Furthermore, the transmission assembly includes a servo motor, which is fixed inside the equipment housing, and a drive gear is fixed to the output end of the servo motor; two rotating shafts, which are rotatably mounted on both sides inside the equipment housing, with the upper ends of both rotating shafts penetrating the upper surface of the equipment housing and being fixedly connected to the first rotating arm and the second rotating arm respectively, and limiting gears are fixedly sleeved on the two rotating shafts; and a linkage gear, which is rotatably mounted inside the equipment housing, located between the drive gear and the limiting gear, and meshing with the drive gear and the limiting gear.
[0012] Furthermore, the front surface of the rack machining tool is fixed with positioning posts, the upper end of the positioning posts is equipped with laser sensors, and the lower surface of the tongue plate is provided with holes and slots adapted to the laser sensors.
[0013] Furthermore, sprockets are rotatably mounted on the upper part of both worktables. The two sprockets are adapted to the chain, and a drive motor is fixed above one of the sprockets, which drives one of the sprockets to rotate.
[0014] Furthermore, a receiving assembly is provided on the workbench. The receiving assembly includes a receiving trough, which is located on the workbench, and a receiving box is slidably installed inside the receiving trough. A handle is installed on the end of the receiving box away from the receiving trough. An inclined plate is located inside the receiving box, and the angle between the inclined plate and the horizontal plane is an acute angle. The height of the inclined plate on the side facing the receiving trough is greater than the height on the other side.
[0015] Furthermore, the outer wall of the workbench is rotatably mounted with stop bars on both sides of the receiving trough, and the receiving box is symmetrically provided with limiting grooves that are adapted to the stop bars.
[0016] The present invention has the following beneficial effects: (1) The rack processing device drives the connecting trolley to move synchronously by hoisting the chain, thereby moving the fixed fixture under the connecting trolley, and then moving the rack body on each rack processing machine tool, which is conducive to the continuous processing of the rack body and improves the working efficiency of rack processing. During the movement of the rack body, the rack body on the fixed fixture can be flipped by the setting of the flipping component, thereby shaking off the processing debris on the rack body and avoiding the rack processing debris from affecting the next processing effect of the rack body. In addition, the chain and rack processing machine tool are coordinated to realize the dual production line setting, which is conducive to improving the conveying effect of the rack body.
[0017] (2) The rack processing device loads and unloads the rack body on both sides of the production line through the loading and unloading components, avoiding manual loading, saving labor costs, improving the loading and unloading efficiency of the rack body and the automation effect of the equipment.
[0018] (3) The rack processing device controls the distance between two rack processing machines on the same side to be the same as the travel path distance between two adjacent connecting trolleys, so that different rack processing machines can process the rack body on it synchronously, thereby making the rack body production line conveying process more stable. The positioning column, laser sensor and hole slot are set to realize the positioning of the hole slot position, and further control the drive motor to stop working so that the rack processing machine can reserve enough time to process the rack body and ensure the stability of the rack body processing.
[0019] (4) The rack processing device facilitates the storage of the rack body after processing by setting up the receiving component. Through the structural characteristics of the inclined plate, the rack body slides along the inclined plate to the bottom of the receiving box, thereby reducing the surface scratches caused by the collision of the rack body during unloading. By rotating the stop bar, the stop bar is embedded in the limiting groove, thereby fixing the receiving box inside the receiving groove, preventing the receiving box from sliding out of the receiving groove and causing a decrease in the receiving effect, thus improving the practicality of the equipment.
[0020] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0024] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.
[0025] Please see Figure 1 - Figure 4 The present invention provides a technical solution: a rack processing device, including a worktable 1, two worktables 1 in total, and a guide rail 10, the guide rail 10 being fixed above the two worktables 1, and connecting trolleys 5 being slidably installed on the guide rail 10 at equal intervals. The stability of the connecting trolleys 5 during movement is improved by the sliding connection between the guide rail 10 and the connecting trolleys 5.
[0026] To drive the movement of the connecting trolley 5, the rack and pinion processing device provided in this embodiment also includes a chain 4. The chain 4 is installed above the guide rail 10 to drive the connecting trolley 5 to move on the guide rail 10. It should be noted that the two worktables 1 are centrally symmetrical about the center of the chain 4. Preferably, the connection between the connecting trolley 5 and the chain 4 is a detachable connection to facilitate the inspection and maintenance of the connecting trolley 5 and the chain 4 in the future.
[0027] Furthermore, to facilitate the processing of the rack body 26, the rack processing device provided in this embodiment also includes a rack processing machine tool 7, which is located between two worktables 1. It should be noted that the rack processing machine tool 7 on the same side is parallel to the straight section of the chain 4, so that a rack processing production line is formed between the rack processing machine tools 7 on the same side. This results in two rack processing production lines in this embodiment, which further enables one chain 4 to feed materials to the two production lines simultaneously, improving the transmission effect of the chain 4. In addition, the distance between the two rack processing machine tools 7 on the same side is the same as the travel path distance between two adjacent connecting trolleys 5, so that the rack body 26 is processed synchronously inside different rack processing machine tools 7. It should be noted that preferably, the number of connecting trolleys 5 is four more than the number of rack processing machine tools 7, so that the rack body 26 on the two production lines can be loaded and unloaded synchronously during processing, which facilitates the clamping of the rack body 26.
[0028] To facilitate the movement of the rack body 26 between rack processing machine tools 7, the rack processing device provided in this embodiment also includes a connecting cylinder 6. The connecting cylinder 6 is fixed to the lower end of the connecting trolley 5, and a connecting frame 13 is fixed to the telescopic end of the connecting cylinder 6. An electric telescopic cylinder 15 is rotatably mounted on the connecting frame 13. The telescopic end of the electric telescopic cylinder 15 is provided with a fixing fixture for fixing the rack body 26 to ensure the stability of the rack body 26 during processing and transportation.
[0029] To facilitate the cleaning of machining debris on the surface of the rack body 26, the rack processing device provided in this embodiment also includes a flipping component. The flipping component is located on the connecting trolley 5 and is used to flip the fixed tooling so that the machining debris on the surface of the rack body 26 is shaken off before entering the downstream rack processing machine tool 7, thereby avoiding the machining debris from affecting the processing of the rack body 26 and improving the practicality of the equipment.
[0030] In this embodiment, the hoisting chain 4 drives the connecting trolley 5 to move synchronously, thereby moving the fixed fixture below the connecting trolley 5. This allows the rack body 26 to move on each rack processing machine tool 7, which facilitates the continuous processing of the rack body 26 and improves the working efficiency of the rack body 26 during processing. During the movement of the rack body 26, the setting of the flipping component allows the processing debris on the surface of the rack body 26 to be shaken off before entering the downstream rack processing machine tool 7, avoiding the processing debris from affecting the processing of the rack body 26 and improving the practicality of the equipment. In addition, the cooperation of the chain 4 and the rack processing machine tool 7 realizes the dual production line setting, which in turn helps to improve the conveying effect of the rack body 26.
[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7As shown, the flipping assembly includes a transmission rack 22 fixed to the outside of the guide rail 10. The transmission rack 22 is located downstream of each rack processing machine tool 7. A transmission gear 24 that meshes with the transmission rack 22 is rotatably mounted inside the connecting trolley 5. Preferably, the length of the transmission rack 22 satisfies an integer number of rotations of the transmission gear 24. The lower end of the connecting trolley 5 is provided with a telescopic tube that is fixedly connected to the center of the transmission gear 24. The lower end of the telescopic tube rises and falls synchronously with the lower end of the connecting cylinder 6. A first bevel gear 40 is installed at the lower end of the telescopic tube. A second bevel gear 41 that meshes with the first bevel gear 40 is installed on the electric telescopic cylinder 15. It should be noted that the first bevel gear 40 can be a worm, and the second bevel gear 41 can be a worm wheel. Through the self-locking effect of the meshing between the worm wheel and the worm, the electric telescopic cylinder 15 can be prevented from rotating actively. The synchronous rise and fall of the lower end of the telescopic tube and the lower end of the connecting cylinder 6 can prevent the first bevel gear 40 from disengaging from the second bevel gear 41, thereby improving the stability during transmission.
[0032] In this embodiment, when the connecting trolley 5 moves on the guide rail 10 to the transmission rack 22, the transmission rack 22 meshes with the transmission gear 24 to make the telescopic tube rotate, which in turn makes the first bevel gear 40 rotate. The first bevel gear 40 meshes with the second bevel gear 41 to make the electric telescopic cylinder 15 rotate, which in turn drives the fixed fixture to flip.
[0033] like Figure 1 , Figure 3 , Figure 4 , Figure 9 and Figure 10 As shown, in order to facilitate the loading and unloading of the rack body 26, the rack processing device provided in this embodiment also includes a loading and unloading assembly. The loading and unloading assembly includes an equipment box 11, which is fixed at the middle position on the workbench 1. A first rotating arm 12 is rotatably installed on one side of the upper end of the equipment box 11, and a second rotating arm 38 is rotatably installed on the other side of the upper end of the equipment box 11.
[0034] It should be noted that the first rotating arm 12 is preferably an unloading arm, mainly used for unloading the rack body 26 on the fixed fixture, and the second rotating arm 38 is a loading arm, mainly used for loading the rack body 26 on the worktable 1 into the fixed fixture. The included angle between the first rotating arm 12 and the second rotating arm 38 is an acute angle to ensure that when the first rotating arm 12 grips the rack body 26 on the fixed fixture, the second rotating arm 38 simultaneously grips the rack body 26 on the worktable 1. During this process, the rotation angle between the first rotating arm 12 and the second rotating arm 38 is the same.
[0035] In addition, the loading and unloading assembly provided in this embodiment also includes a lifting cylinder 31. The lifting cylinder 31 is fixed to the end of the first rotating arm 12 and the second rotating arm 38 away from the equipment box 11, and the extension end of the lifting cylinder 31 is equipped with a suction cup 32 for gripping the rack body 26. Of course, the suction cup 32 can also be an electromagnet. By magnetically attracting the rack body 26 with the electromagnet, the rack body 26 can be gripped, so as to avoid the problem of difficulty in gripping the rack body 26 after the rack body 26 has been processed.
[0036] In addition, in order to drive the first rotating arm 12 and the second rotating arm 38 to rotate synchronously, the loading and unloading assembly provided in this embodiment also includes a transmission assembly. The transmission assembly is located inside the equipment box 11 to drive the first rotating arm 12 and the second rotating arm 38 to rotate in the same direction, thereby facilitating the synchronous unloading and clamping of the rack body 26.
[0037] like Figure 3 and Figure 4 As shown, the telescopic tube provided in this embodiment includes a sleeve 30 fixed to the lower end of the connecting trolley 5. A lifting rod 39 is slidably installed inside the sleeve 30. Preferably, the cross-section of the lifting rod 39 is a regular polygon to prevent the lifting rod 39 from rotating inside the sleeve 30.
[0038] In addition, to prevent the first bevel gear 40 from disengaging from the second bevel gear 41 and to improve the stability of the transmission between the first bevel gear 40 and the second bevel gear 41, a connecting plate 42 is fixed at the telescopic end of the connecting cylinder 6. The lifting rod 39 is rotatably connected to the connecting plate 42, and the lower end of the lifting rod 39 is fixedly connected to the first bevel gear 40 to ensure that the first bevel gear 40 and the second bevel gear 41 rise and fall synchronously.
[0039] like Figure 1 , Figure 3 , Figure 7 and Figure 8 As shown, the fixed tooling tongue plate 14 provided in this embodiment is located at the lower inner side of the connecting frame 13. The tongue plate 14 and the connecting frame 13 are fixedly connected, which can be bolted, riveted or welded. It should be noted that the connecting frame 13 is preferably an inverted "U" structure to facilitate the installation of the tongue plate 14.
[0040] To facilitate the bearing of the rack body 26, the fixed fixture provided in this embodiment also includes a support frame 23. The support frame 23 is located above the tongue plate 14, and one side of the support frame 23 is fixedly connected to the telescopic end of the electric telescopic cylinder 15. The upper surface of the support frame 23 is provided with a mounting groove 25, which is used to hold the rack body 26. Preferably, the mounting groove 25 is open on the side facing the rack processing machine tool 7 and on its upper surface, so as to facilitate the processing and loading / unloading of the rack body 26 inside the mounting groove 25. Preferably, the upper surface of the tongue plate 14 near the rack processing machine tool 7 is a sloping structure, so as to allow the support frame 23 to move on the tongue plate 14.
[0041] In this embodiment, the electric telescopic cylinder 15 drives the support frame 23 to move, thereby allowing the support frame 23 to extend into the rack processing machine tool 7 and realize the horizontal movement of the support frame 23. This facilitates the rack processing machine tool 7 to directly process the rack body 26 on the mounting slot 25.
[0042] To fix the rack body 26, the fixing fixture provided in this embodiment also includes a pressure plate 27. The pressure plate 27 is installed at both ends inside the mounting groove 25. The outer ends of the support frame 23 are fixed with clamping cylinders 28 for driving the pressure plates 27 to move in opposite directions. Preferably, the upper end of the pressure plate 27 has an arc-shaped structure so that the two pressure plates 27 form an inverted "V" structure. The rack body 26 can be installed without precisely aligning it with the mounting groove 25, which improves the error tolerance during the installation of the rack body 26. It should be noted that in order to improve the machining accuracy of the rack body 26, the pressure plate 27 is preferably a workpiece made of metal, such as stainless steel, pure copper or aluminum alloy, to avoid deformation of the pressure plate 27 causing the rack body 26 to shift after clamping, which would result in a decrease in machining accuracy.
[0043] like Figure 10 As shown, the transmission assembly provided in this embodiment includes a servo motor 33, which is fixed inside the equipment housing 11. A drive gear 34 is fixed to the output end of the servo motor 33. The transmission assembly also includes a rotating shaft 36, which is rotatably mounted on both sides inside the equipment housing 11. Bearings are provided at the connection points between both ends of the rotating shaft 36 and the equipment housing 11 to facilitate the rotation of the rotating shaft 36. The upper ends of both rotating shafts 36 penetrate the upper surface of the equipment housing 11 and are fixedly connected to the first rotating arm 12 and the second rotating arm 38, respectively. Preferably, the fixed connection is achieved by welding to ensure the stability of the first rotating arm 12 and the second rotating arm 38 after installation. Furthermore, a limiting gear 37 is fixedly sleeved on both rotating shafts 36, preferably a half-gear. The transmission assembly also includes a linkage gear 35, which is rotatably mounted inside the equipment housing 11. The linkage gear 35 is located between the drive gear 34 and the limiting gear 37, and meshes with both the drive gear 34 and the limiting gear 37.
[0044] In this embodiment, the servo motor 33 drives the drive gear 34 to rotate. Through the meshing between the drive gear 34 and the linkage gear 35, the linkage gear 35 rotates. Furthermore, through the meshing between the linkage gear 35 and the limit gear 37, the limit gear 37 drives the rotating shaft 36 to rotate, thereby causing the first rotating arm 12 and the second rotating arm 38 to rotate respectively.
[0045] like Figure 1 , Figure 3 and Figure 8As shown, in order to facilitate the positioning of the rack body 26 during processing, positioning posts 8 are fixed on the front surface of the rack processing machine tool 7. A laser sensor is provided at the upper end of the positioning post 8, and a slot 29 adapted to the laser sensor is opened on the lower surface of the tongue plate 14.
[0046] It should be noted that the laser sensor is a sensor that uses laser technology for measurement. It consists of a laser, a laser detector, and a measurement circuit. Its advantages include non-contact long-distance measurement, high speed, high accuracy, large range, and strong resistance to light and electrical interference. Using the above principle, we measure the distance between the positioning post 8 and the tongue plate 14 using the laser sensor. When the hole 29 on the tongue plate 14 corresponds to the laser sensor, the distance measured by the laser sensor increases. This allows us to determine the position of the hole 29 and thus achieve the positioning of the rack body 26 during machining.
[0047] like Figure 1 - Figure 5 As shown, to facilitate the driving of the chain 4, sprockets 2 are rotatably mounted on the upper ends of both workbenches 1. The two sprockets 2 are adapted to the chain 4, and a drive motor 3 is fixed above one of the sprockets 2. The drive motor 3 drives one of the sprockets 2 to rotate. Through the drive motor 3, one of the sprockets 2 rotates, and under the transmission action of the sprockets 2 and the chain 4, the chain 4 works.
[0048] It should be noted that, for the convenience of controlling the operation of this equipment, a control cabinet 16 is installed on the workbench 1. The signal input terminal of the control cabinet 16 is electrically connected to the signal output terminal of the laser sensor, and the signal output terminal of the control cabinet 16 is electrically connected to the drive motor 3, the servo motor 33, and the electric telescopic cylinder 15 respectively. When the control cabinet 16 receives the distance signal from the laser sensor, it ensures that the distance signal is the same as the distance between the positioning column 8 and the slot 29, thereby positioning the position of the slot 29, and then positioning the position of the fixed fixture. At this time, the control cabinet 16 sends a signal to control the drive motor 3 to stop working, so that the fixed fixture position remains stationary. The control cabinet 16 controls the servo motor 33 to make the first rotating arm 12 and the second rotating arm 38 rotate respectively, realizing the synchronous unloading and clamping of the rack body 26. The control cabinet 16 controls the electric telescopic cylinder 15 to extend, thereby allowing the rack body 26 to enter the rack processing machine tool 7, thereby realizing the synchronous processing of the rack body 26.
[0049] like Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, in order to facilitate the storage of the rack body 26 on the workbench 1, a receiving assembly is provided on the workbench 1. The receiving assembly includes a receiving trough 17, which is located on the workbench 1. A receiving box 9 is slidably installed inside the receiving trough 17 to facilitate the movement of the receiving box 9. A handle 19 is installed at the end of the receiving box 9 away from the receiving trough 17, which facilitates the pulling of the receiving box 9 and thus facilitates the collection of the rack body 26 inside the receiving box 9.
[0050] To prevent the rack body 26 from being scratched during unloading due to collision, the receiving assembly provided in this embodiment also includes an inclined plate 18. The inclined plate 18 is located inside the receiving box 9, and the angle between the inclined plate 18 and the horizontal plane is an acute angle. The height of the side of the inclined plate 18 facing the receiving groove 17 is greater than the height of the other side. Preferably, the inclined plate 18 is made of rubber to improve the buffering effect when the rack body 26 is unloaded. When the rack body 26 is unloaded, it falls onto the inclined plate 18. Through the structural characteristics of the inclined plate 18, the rack body 26 slides along the inclined plate 18 to the bottom of the receiving box 9, thereby reducing the surface scratches caused by collision during unloading.
[0051] like Figure 5 and Figure 6 As shown, to facilitate the fixing of the receiving box 9, a stop bar 21 is rotatably installed on both sides of the receiving trough 17 on the outer wall of the workbench 1. The receiving box 9 is symmetrically provided with a limiting groove 20 that matches the stop bar 21. By rotating the stop bar 21, the stop bar 21 is embedded in the limiting groove 20, thereby fixing the receiving box 9 inside the receiving trough 17 and preventing the receiving box 9 from sliding out of the receiving trough 17, which would reduce the receiving effect.
[0052] In addition, the receiving component can also be a first conveyor belt set on the workbench 1, so that the rack body 26 can be placed directly on the first conveyor belt during unloading, thereby transporting the rack body 26 outside the equipment. Of course, a second conveyor belt can also be set on the workbench 1. The second conveyor belt is mainly used for feeding the rack body 26 blank and transporting the rack body 26 blank to the workbench 1 so that the suction cup 32 on the second rotating arm 38 can grab the rack body 26 blank.
[0053] During use (operation), the lifting cylinder 31 is activated, and the height of the suction cup 32 is adjusted so that the suction cup 32 grips the rack body 26. The servo motor 33 is activated, which drives the drive gear 34 to rotate. Through the meshing between the drive gear 34 and the linkage gear 35, the linkage gear 35 rotates. Furthermore, through the meshing between the linkage gear 35 and the limit gear 37, the limit gear 37 drives the rotating shaft 36 to rotate, thereby causing the first rotating arm 12 and the second rotating arm 38 to rotate respectively. This further moves the rack body 26 on the fixed fixture to above the receiving trough 17, and moves the rack body 26 blank on the worktable 1 to the fixed fixture. At this time, the two suction cups 32 release the rack body 26 and the rack body 26 blank respectively, so that the rack body 26... 6. When the rack body 26 is unloaded, it falls onto the inclined plate 18. Due to the structural characteristics of the inclined plate 18, the rack body 26 slides along the inclined plate 18 to the bottom of the receiving box 9, thereby reducing the surface scratches caused by the collision during unloading. The inverted "V" structure formed between the two pressure plates 27 allows the rack body 26 blank to be installed without precise alignment with the mounting groove 25, improving the error tolerance during installation. After the rack body 26 blank moves into the mounting groove 25, the clamping cylinder 28 is activated, causing the pressure plates 27 to move towards each other, thereby clamping the rack body 26 blank and improving the stability of the rack body 26 blank during subsequent processing.
[0054] At this time, the drive motor 3 is started, which causes one of the sprockets 2 to rotate. Under the transmission action of the sprocket 2 and the chain 4, the chain 4 works, which further moves the fixed fixture under the connecting trolley 5, and then causes the rack body 26 to move on each rack processing machine tool 7. This facilitates the continuous processing of the rack body 26 and improves the working efficiency of the rack body 26. Through the cooperation of the chain 4 and the rack processing machine tool 7, a dual production line setting is realized, which in turn improves the conveying effect of the rack body 26. When the connecting trolley 5 moves on the guide rail 10 to the transmission rack 22, the transmission rack 22 meshes with the transmission gear 24, causing the telescopic tube to rotate, which in turn causes the first bevel gear 40 to rotate. The first bevel gear 40 meshes with the second bevel gear 41, causing the electric telescopic cylinder 15 to rotate, which in turn drives the fixed fixture to flip. This causes the processing debris on the surface of the rack body 26 to be shaken off before entering the downstream rack processing machine tool 7, avoiding the processing debris from affecting the processing of the rack body 26 and improving the practicality of the equipment.
[0055] When the fixed fixture passes the positioning post 8, the control cabinet 16 receives the distance signal from the laser sensor to ensure that the distance signal is the same as the distance between the positioning post 8 and the slot 29, thereby positioning the position of the slot 29 and then positioning the fixed fixture. At this time, the control cabinet 16 sends a signal to control the drive motor 3 to stop working, so that the fixed fixture remains stationary. The control cabinet 16 controls the servo motor 33 to make the first rotating arm 12 and the second rotating arm 38 rotate respectively, realizing the synchronous unloading and clamping of the rack body 26. The control cabinet 16 controls the electric telescopic cylinder 15 to extend, so that the rack body 26 enters the rack processing machine tool 7, thereby realizing the synchronous processing of the rack body 26.
