Description

Technical Field

[0001] This invention belongs to the field of workpiece conveying technology, and specifically relates to an online conveying system for gear hubs. Background Technology

[0002] Synchronizer gear hubs are important components of automotive transmissions. The accuracy of various parameters during machining is a crucial standard for ensuring the stability and safety of gear shifting. Therefore, after the production of gear hub parts, their parameters must be measured to ensure that the produced gear hubs meet the required precision.

[0003] Both sides of the synchronizer gear hub need to be inspected under a comparator. The comparator is equipped with a dustproof cover, and due to limited space, it cannot be flipped on the spot after measuring one side. The traditional method is to manually remove the synchronizer gear hub, flip it, and then place it under the comparator for inspection after one side is inspected. However, manual flipping suffers from low efficiency and inaccurate positioning. With the continuous development of automation technology in the manufacturing industry, full automation of product production lines has become the mainstream trend. As the main working component, the transmission part requires the design of new automatic conveying mechanisms to meet the demands, enabling it to complete conveying and flipping along a specific path as required. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides an online conveying system for gear hubs and an online measurement and conveying method, enabling workpieces to be conveyed and rotated along a specific path as required.

[0005] To achieve the above objectives, the present invention provides an online gear hub conveying system, comprising a tilting mechanism, a conveying mechanism, a positioning mechanism, and a controller; the tilting mechanism includes a vertical lifting mechanism, on which a horizontal telescopic mechanism is mounted, and on which a rotating mechanism is mounted, and on which a clamping mechanism for clamping the gear hub is mounted; the positioning mechanism includes a horizontal moving mechanism, on which a rotary cylinder is slidably mounted, and the rotary table of the rotary cylinder is fixedly connected to the rotating body; a gear positioning column is mounted on the conveying mechanism; the controller is used to control the power sources of the tilting mechanism, the conveying mechanism, and the positioning mechanism; in the initial state, the tilting mechanism and the horizontal moving mechanism are located on both sides of the conveying mechanism.

[0006] Furthermore, the vertical lifting mechanism includes a vertical lifting support, on which a vertical guide rail and a first ball screw pair are mounted. A first slider is slidably mounted on the vertical guide rail, and a horizontal telescopic mechanism is mounted on the first nut seat of the first ball screw pair.

[0007] Furthermore, the horizontal telescopic mechanism includes a horizontal telescopic support mounted on the vertical lifting mechanism. A second ball screw pair and a horizontal guide rail are mounted on the horizontal telescopic support. A rotating mechanism is mounted on the second nut seat of the second ball screw pair. The second nut seat is slidably connected to the horizontal guide rail via a second slider.

[0008] Furthermore, the rotating mechanism includes a rotary table support, on which a rotating part and an electric cylinder are mounted. The electric cylinder includes an electric cylinder motor part and an electric cylinder rod part that are fixedly connected. The electric cylinder motor part is used to drive the electric cylinder rod part to move horizontally.

[0009] Furthermore, the clamping mechanism includes an internal pull rod and a support block. A housing is fixed to one side of the support block. The internal pull rod passes through the support block and is interference-fitted with the electric cylinder rod. It is also hinged to one end of the arm. The arm is a curved rod, including a horizontal rod and an inclined rod fixedly connected to the horizontal part. The connection between the horizontal rod and the horizontal part is mounted on the housing by a pin. A clamping component is fixed to the inner side of the other end of the arm.

[0010] Furthermore, the conveying mechanism includes a base, on which a third ball screw pair is mounted. A slider panel is mounted on the nut seat connector of the third ball screw pair. The slider panel is slidably connected to the first guide rail via a third slider. A gear positioning column and a spring-type trigger switch are mounted on the slider panel. A limit support is fixed near the edge. The spring-type trigger switch passes through the limit support and the slider panel. A displacement sensor is located directly below the spring-type trigger switch.

[0011] Furthermore, the horizontal movement mechanism includes a horizontal movement support, on which a fourth ball screw pair is mounted, and a rotary cylinder is mounted on the third nut seat of the fourth ball screw pair; the rotary cylinder is slidably connected to the second guide rail via a fourth slider.

[0012] Furthermore, the rotating body includes a rotating part, on which a rubber pad is fixed.

[0013] A method for online measurement and conveying of a gear hub based on the above-mentioned conveying system includes the following steps:

[0014] S1. Place the device of the present invention at the production line end of the synchronizer hub so that the arm of the clamping mechanism is in the maximum open state.

[0015] S2. When the synchronizer hub passes directly below the clamping mechanism, the vertical lifting mechanism starts to operate, driving the clamping mechanism to descend vertically until the clamping mechanism is at the same height as the synchronizer hub.

[0016] S3. After clamping the synchronizer hub with the clamping mechanism, raise the clamping mechanism vertically to a position higher than the rotating body, extend the clamping mechanism horizontally to move the synchronizer hub towards the rotating body to a position directly above the gear positioning post, lower the clamping mechanism vertically until the synchronizer hub is placed on the gear positioning post, release the synchronizer hub with the clamping mechanism, and then raise the clamping mechanism vertically to a position higher than the rotating body using the vertical lifting mechanism.

[0017] S4. Move the rotating body horizontally toward the synchronizer hub until they contact each other; start the rotary cylinder to reciprocate, driving the rotating body to rotate. The rotating body rotates the synchronizer hub through friction, causing the gear positioning pin to form a transition fit with the synchronizer hub, completing the positioning. The position of the synchronizer hub at this time is recorded as the initial position, and the rotating body is reset.

[0018] S5. Move the conveying mechanism to move the synchronizer hub toward the comparator to the detection position;

[0019] S6. After the comparison instrument completes the test, the conveying mechanism transports the synchronizer hub to the initial position. At the same time, the vertical lifting mechanism is controlled to drive the clamping mechanism to descend vertically until the clamping mechanism and the synchronizer hub are at the same height. After the clamping mechanism clamps the synchronizer hub, the clamping mechanism is raised vertically. Then, the rotating mechanism is controlled to rotate the synchronizer hub to 30°. Finally, the synchronizer hub is placed back on the gear positioning column.

[0020] S7. Move the synchronizer hub towards the comparator to the detection position using the conveying mechanism to complete the detection of the other side of the synchronizer hub.

[0021] Compared with the prior art, the present invention has at least the following beneficial technical effects:

[0022] The online conveying system for gear hubs described in this invention can transport and flip specified parts to a designated position. After one side of the part is inspected, the conveying mechanism transports the workpiece to the initial position, the clamping mechanism picks up the part and lifts it up, the rotating mechanism drives the part to flip 180°, and then the conveying mechanism transports it to a designated position to complete the inspection of the other side, which can improve the efficiency of the production line.

[0023] The use of automated production lines for processing and manufacturing mechanical parts can integrate all production processes. The use of automatic flipping devices to flip workpieces can improve the labor productivity of enterprises, significantly reduce the labor intensity of workers, improve the economic benefits of enterprises, improve the working environment of operators, and improve product quality.

[0024] Furthermore, when the clamping mechanism places the synchronizer hub on the gear positioning post, it cannot immediately complete the positioning requirements of the hub, but it can restrict its movement in the vertical direction. At this time, the horizontal moving mechanism sends the rotating body to the contact position with the workpiece. Under the drive of the rotary cylinder, the rubber pad drives the workpiece to rotate, so that the synchronizer hub and the gear positioning post form a transition fit, so that the central axis of the synchronizer hub and the rotating body are kept on the same axis, thus completing the workpiece positioning and ensuring the accuracy of the positioning.

[0025] Furthermore, the vertical lifting mechanism, horizontal telescopic mechanism, conveying mechanism, and horizontal moving mechanism all adopt ball screw pairs. The ball screw pair is made by machining threads at the mating point of the nut and the screw. When the screw and the matching nut are mated, balls are added into the gap between the two threads, which changes the original sliding friction force into rolling friction force, thereby greatly reducing frictional resistance, reducing wear on the mechanism, and greatly improving its service life and mechanical efficiency.

[0026] The online measurement and conveying method for toothed hubs provided by this invention utilizes the aforementioned device to conveniently transport toothed hubs to the underside of a comparator for inspection. After one side of the toothed hub is inspected, it is transported to a position where it can be flipped over, and then transported back to the underside of the comparator to complete the inspection of the other side of the toothed hub, thereby improving the accuracy of the toothed hub position and production line efficiency.

[0041] Reference Figure 1 A gear hub online conveying system includes a tilting mechanism, a conveying mechanism 6, a positioning mechanism, and a controller. The tilting mechanism includes a vertical lifting mechanism 1, a horizontal telescopic mechanism 2, a rotating mechanism 3, and a clamping mechanism 4. The positioning mechanism includes a rotating body 7, a rotary cylinder 8, and a horizontal moving mechanism 9.

[0042] Among them, the first nut seat 106 of the horizontal telescopic mechanism 2 and the vertical lifting mechanism 1, the rotating mechanism 3 and the horizontal telescopic mechanism 2, and the horizontal moving mechanism 9 and the outer shell of the rotary cylinder 8 are all connected by bolts; the support block of the clamping mechanism 4 is fastened to the rotating outer shell 305 of the rotating mechanism 3 by screws, and the internal control of the clamping mechanism 4 by the rotating mechanism 3 is realized by interference fit; the rotating body 7 and the rotary cylinder 8 are connected by bolts, so that the rotary cylinder 8 controls the rotating body 7.

[0043] like Figure 2As shown, the vertical lifting mechanism 1 is used to drive the horizontal telescopic mechanism 2 to move vertically. It includes a vertical lifting support 101, a first motor 102, a first motor base 103, a first coupling 104, a first fixed end support unit 105, a first nut seat 106, a first slider 107, a first ball screw 108, a first support end support unit 109, and a vertical guide rail 110. The first motor 102 is mounted on the vertical lifting support 101 and is bolted to the first motor base 103. The first coupling 104 is connected to the power output shaft of the first motor 102. The first coupling 104 is keyed to the first ball screw 108. The first ball screw 108 is threadedly engaged with the first nut seat 106, ensuring that the horizontal telescopic mechanism 2 mounted on the first nut seat 106 can slide in the vertical direction.

[0044] The first fixed end support unit 105 and the first support end support unit 109 are cuboid in shape. The lower end is fixed to the side wall of the vertical lifting support 101 by a thin plate. The first ball screw 108 is fixedly supported. The lower end is connected to the first fixed end support unit 105 by an angular contact ball bearing 7204ADF, and the upper end is connected to the first support end support unit 109 by a deep groove ball bearing 6004ZZ.

[0045] Two vertical guide rails 110 are fixed on the vertical lifting support 101, parallel to each other, located on both sides of the first ball screw 108. The vertical guide rails 110 are slidably engaged with the first slider 107. The first slider 107 is fixedly connected to the horizontal telescopic support 201 by bolts. The four first sliders 107 are distributed in a rectangular shape on the two vertical guide rails 110.

[0046] The longitudinal central axes of the first motor 102, the first motor base 103, the first coupling 104, the first fixed end support unit 105, the first nut seat 106, the first ball screw 108, and the first support end support unit 109 are kept on the same axis.

[0047] The horizontal telescopic mechanism 2 includes a horizontal telescopic support 201, a second motor 202, a second motor base 203, a second coupling 204, a second fixed end support unit 205, a second nut seat 206, a second slider 207, a second ball screw 208, a second support end support unit 209, and a horizontal guide rail 210. The second motor 202 is mounted on the horizontal telescopic support 201 and is bolted to the second motor base 203. The second coupling 204 is connected to the power output shaft of the second motor 202. The second coupling 204 is keyed to the second ball screw 208. The second ball screw 208 is threadedly engaged with the second nut seat 206 to ensure that the rotating mechanism 3 on the second nut seat 206 can slide in the horizontal direction.

[0048] Two parallel horizontal guide rails 210 are fixed on the horizontal telescopic support 201. The horizontal guide rails 210 are slidably engaged with the second slider 207. The second slider 207 is fixedly connected to the rotary table support 302 by bolts. The four second sliders 207 are distributed in a rectangular shape on the two horizontal guide rails 210.

[0049] The horizontal telescopic support 201 is equipped with a second ball screw 208, which is selected for fixed support. One end of the second fixed end support unit 205 is connected to the second fixed end support unit 205 through an angular contact ball bearing 7001ADF, and the other end is connected to the second support end support unit 209 through a deep groove ball bearing 6000ZZ.

[0050] The second fixed end support unit 205, the second support end support unit 209 and the horizontal telescopic support 201 are fixedly connected by screws.

[0051] The rotating mechanism 3 includes a third motor 301, a rotary table support 302, a rotary table support part 303, a rotating part 304, and an electric cylinder. The third motor 301 and the rotary table support part 303 are both bolted to the rotary table support 302. The rotary table support part 303 and the rotating part 304 are clearance-fitted to ensure that the clamping mechanism 4 can be flipped.

[0052] The power output shaft of the third motor 301 is connected to the central shaft of the rotating part 304 by gears, with a transmission ratio of 4:1.

[0053] The rotating part 304 is connected to the rotating housing 305 by bolts, and the electric cylinder housing part 307 is fixedly installed inside the rotating housing 305.

[0054] The electric cylinder includes an electric cylinder motor part 306, an electric cylinder rod part 308, and an electric cylinder housing part 307 connected by bolts. The electric cylinder housing part 307 and the electric cylinder rod part 308 are clearance-fitted. The electric cylinder motor part 306 is used to drive the electric cylinder rod part 308 to move horizontally.

[0055] like Figure 3As shown, the clamping mechanism 4 includes an internal pull rod 401, a support block 402, a cylindrical pin 403, a housing 404, a pin 405, an arm 406, and a clamping component 407. Two arms 406 are arranged opposite each other. Each arm 406 is a curved rod, including a horizontal rod and an inclined rod fixedly connected to the horizontal part. The angle between the horizontal rod and the inclined rod is greater than 120 degrees. The support block 402 is fastened to the rotating housing 305 with screws. The internal pull rod 401 passes through the support block 402 and is interference-fitted with the electric cylinder rod part 308. It is also connected to one end of the arm 406 via the cylindrical pin 403. The horizontal rod of the arm 406 and its connection to the horizontal part are mounted on the housing 404 via the pin 405, ensuring that the rotating mechanism 3 controls the clamping mechanism 4. The other end of the arm 406 is fixedly connected to the clamping component 407 with screws. A first positioning sensor is provided on one side of the housing 404 along the positive X direction, a second positioning sensor is provided inside one clamping member 407, and a pressure sensor is provided inside the other clamping member 407. (The second positioning sensor and the pressure sensor are respectively provided inside the two clamping members 407)

[0056] The electric cylinder rod 308 can drive the pull rod 401 to extend and retract, thereby driving the arm 406 to open and close. The maximum opening and closing angle of the arm 406 is 20°.

[0057] The internal tie rod 401, arm 406, and cylindrical pin 403 are all clearance fits.

[0058] like Figure 4 As shown, the conveying mechanism 6 includes a base 613. Four spaced track supports 618 are fixed at the lower end of the base 613. The base 613 is made of 2080 aluminum profile. Two straight first guide rails 612 are fixed at the upper end of the base 613 to ensure the movement distance of the straight first guide rails 612 and prevent slippage during movement. Four bolt holes are provided on the cross-section of the base 613 to fix the motor fixing plate 602 and the front fixing plate 614 to the front and rear ends of the base 613. The first guide rails 612 are bolted together above the base 613 to ensure the stability of the guide rails on the base.

[0059] The first guide rail 612 is an SSR-XW type linear guide rail, which, through an transition fit, achieves the limiting function of the third slider 611, ensuring that the third slider 611 can only slide in the horizontal direction.

[0060] The third slider 611 has a threaded hole on its upper part, which can be used to fix the slider panel 610 to the third slider 611 with screws.

[0061] The inner diameter of the nut seat connector 609 is connected to the outer diameter of the third ball screw 606 by a thread, and the upper surface of the nut seat connector 609 is connected to the slider panel 610 by bolts during assembly.

[0062] Threads are machined at the mating point between the nut seat connector 609 and the third ball screw 606. When the third ball screw 606 is working, balls are added into the gap between the two threads. When the ball screw rotates due to the torque transmitted by the fourth motor 601, the balls also roll, driving the nut seat connector 609 and the slider panel 610 to move.

[0063] During assembly, intermediate fixing plates 604 and front fixing plates 614 need to be installed at both ends of the third ball screw 606 to fix and connect the overall device. Threaded holes are machined on the bottom of the intermediate fixing plate 604 and the front fixing plate 614 to fit and fix with the threaded holes of the base 613. Bearing holes are machined between the intermediate fixing plate 604 and the front fixing plate 614. During assembly, bearings 615 are installed to connect the spindle of the third ball screw 606 and the fourth motor 601.

[0064] The longitudinal central axes of the fourth motor 601, motor mounting plate 602, third coupling 603, intermediate mounting plate 604, nut seat connector 609, and front mounting plate 614 are kept on the same axis and arranged sequentially along the positive Y direction.

[0065] Two limiters 605 are respectively fixed to the side of the intermediate fixed plate 604 that contacts the third ball screw 606 and the side of the front fixed plate 614 that contacts the third ball screw 606 by bolts. When the limiters 605 are installed, they are kept at the same height as the slider panel 610. A sixth positioning sensor is provided on the limiters 605 connected to the intermediate fixed plate 604.

[0066] The bushings of the third coupling 603 are machined according to the spindle diameters of the third ball screw 606 and the fourth motor 601. The bushings on both sides mate with the spindles of the third ball screw 606 and the fourth motor 601, respectively. Bolt holes and a pre-reserved clearance are designed on one side of the bushing in the vertical direction. After the two shafts are mated with the coupling bushings, screws are used to tighten both ends of the pre-reserved clearance of the coupling, completing the connection between the spindles of the third ball screw 606 and the fourth motor 601. A limit support 619 is fixed near the edge of the slider panel 610. A spring-loaded trigger switch 616 passes through the limit support 619 and the slider panel 610. A displacement sensor 617 is located below the spring-loaded trigger switch 616 and is used to measure the displacement of the synchronizer hub 5 in the vertical direction of the gear positioning post 607. It is also aligned with the spring-loaded trigger switch 616. The lower end of the clamp support 608 is connected to the slider panel 610 with screws, and the upper end is fitted with the gear positioning post 607.

[0067] The spring-type trigger switch 616 is clearance-fitted with the limit support 619, and the limit support 619 is connected to the slider panel 610 by bolts. In the initial state, the upper end face of the spring at the top of the spring-type trigger switch 616 is higher than the lower end face of the synchronizer hub 5 sleeved on the gear positioning column 607. A fourth positioning sensor is provided on the upper side of the limit support 619.

[0068] When the synchronizer hub 5 is positioned on the gear positioning post 607, the spring-type trigger switch 616 is in direct contact with the edge of the synchronizer hub 5, generating pressure on the spring-type trigger switch 616. When the synchronizer hub 5 is in position and presses the spring-type trigger switch 616, and the displacement sensor 617 reaches the set displacement amount, the synchronizer hub 5 is successfully positioned and forms a transition fit with the gear positioning post 607.

[0069] like Figure 5 As shown, the horizontal moving mechanism 9 includes a horizontal moving support 901, a third fixed end support unit 905, a third support end support unit 909, and a fifth motor 902. The third fixed end support unit 905, the third support end support unit 909, and the fifth motor 902 are all mounted above the horizontal moving support 901. The horizontal moving support 901 is connected to the third motor base 903 by bolts. The power output shaft of the fifth motor 902 is connected to the fourth coupling 904. The fourth coupling 904 is keyed to one end of the fourth ball screw 908. The fourth ball screw 908 is clearance-fitted with the third nut seat 906 to ensure that the rotary cylinder 8 on the nut seat can slide in the horizontal direction.

[0070] The fourth ball screw 908 is selected for fixed support and is connected to the third fixed end support unit 905 through an angular contact ball bearing 7204ADF, and to the third support end support unit 909 through a deep groove ball bearing 6004ZZ.

[0071] Two parallel second guide rails 910 are fixed on the horizontal moving support 901. The second guide rails 910 are slidably engaged with the fourth slider 907. The fourth slider 907 is fixedly connected to the rotary cylinder 8 by bolts. The four fourth sliders 907 are distributed in a rectangular shape on the two second guide rails 910.

[0072] The longitudinal central axes of the fifth motor 902, the third motor base 903, the fourth coupling 904, the third fixed end support unit 905, the third nut seat 906, the fourth ball screw 908, and the third support end support unit 909 are kept on the same axis.

[0073] The connecting plate 911 is located between the rotary cylinder 8 and the horizontal moving mechanism 9, and is connected to the rotary cylinder 8 and the third nut seat 906 by bolts.

[0074] The rotating body 7 includes a rotating part 702 and a rubber pad 701. The rotating table 801 of the rotary cylinder 8 is connected to the rotating part 702 by bolts. The rubber pad 701 is embedded in the rotating part 702. A third positioning sensor is provided on the upper side of the rubber pad 701, and a fifth positioning sensor is provided on the negative X-direction side of the rubber pad 701.

[0075] The controller's input terminals are connected to the first, second, third, fourth, fifth, and sixth position sensors, a pressure sensor, a displacement sensor 617, and a comparator. The output terminals are connected to the first motor 102, the second motor 202, the third motor 301, the electric cylinder motor section 306, the fourth motor 601, the fifth motor 902, the rotary cylinder 8, and the comparator. Depending on the requirements, the first to fourth position sensors are infrared sensors, the fifth and sixth position sensors are limit switches, the pressure sensor is a capacitive pressure sensor, and the displacement sensor 617 is a linear displacement sensor.

[0076] An online measurement and delivery method includes the following steps:

[0077] When the device described in this invention is placed at the end of the synchronizer hub production line, and the synchronizer hub 5 reaches directly below the clamping mechanism 4 via the conveyor belt, it is detected by the first positioning sensor. The first positioning sensor sends a signal to the controller. After receiving the signal, the controller starts the first motor 102. The first motor 102 is connected to the first ball screw 108 via the first coupling 104, which drives the first nut seat 106 to vertically lower the clamping mechanism 4. At this time, the arm 406 is in its maximum open state. When the clamping component 407 is horizontal with the synchronizer hub 5, it is detected by the second positioning sensor. The second positioning sensor sends a signal to the controller. After receiving the signal, the controller controls the first motor 102 to shut off, the clamping mechanism 4 stops descending, and simultaneously starts the electric cylinder motor 3. 06. The electric cylinder motor 306 drives the arm 406 to clamp the synchronizer hub 5 via the electric cylinder rod 308. This is detected by a pressure sensor, which sends a pressure signal to the controller. After receiving the pressure signal, the controller determines whether the pressure is greater than the set value. When the pressure is greater than the set value, the electric cylinder motor 306 is turned off, and the first motor 102 is started to make the clamping mechanism 4 rise vertically. When the synchronizer hub 5 rises above the rotating body 7, it is detected by the third positioning sensor, which sends a signal to the controller. After receiving the signal, the controller controls the first motor 102 to turn off, the clamping mechanism 4 stops rising, and the second motor 202 is started. The second motor 202 is connected to the second ball screw 208 via the second coupling 204, so that the second... The nut seat 206 drives the clamping mechanism 4 to extend horizontally. The clamping mechanism 4 drives the synchronizer hub 5 to move in the positive X direction. When the axis of the synchronizer hub 5 is aligned with the axis of the gear positioning column, it is detected by the fourth positioning sensor. The fourth positioning sensor sends a signal to the controller. After receiving the signal, the controller controls the second motor 202 to shut off, and the clamping mechanism 4 stops extending. At the same time, the first motor 102 is started to make the clamping mechanism 4 descend vertically, placing the synchronizer hub 5 on the gear positioning column 607. The synchronizer hub 5 presses the spring-type trigger switch 616 when it is in position. After the displacement sensor 617 reaches the first displacement amount, it sends a signal to the controller. After receiving the signal, the controller controls the first motor 102 to shut off, and the clamping mechanism 4 stops descending. At the same time, it controls the electric cylinder motor. Part 306 resets, arm 406 releases synchronizer hub 5 to reach maximum opening angle, then the controller controls electric cylinder motor part 306 to close, and simultaneously starts first motor 102 to make clamping mechanism 4 rise vertically. When clamping mechanism 4 rises above rotating body 7, it is detected by third positioning sensor. Third positioning sensor sends a signal to controller. After receiving the signal, controller controls first motor 102 to close, clamping mechanism 4 stops rising, and simultaneously starts fifth motor 902. Fifth motor 902 is connected to fourth ball screw 908 through fourth coupling 904, driving third nut seat 906 to make rotating body 7 move horizontally towards synchronizer hub 5. When rubber pad 701 contacts synchronizer hub 5, fifth positioning sensor sends a signal to controller.After receiving the signal, the controller shuts off the fifth motor 902, stopping the movement of the rotating body 7. Simultaneously, it starts the rotary cylinder 8 for reciprocating rotation, driving the rotating part 702 and the rubber pad 701 to rotate. The rubber pad 701, through friction, causes the synchronizer hub 5 to rotate, creating a transition fit between the gear positioning pin 607 and the synchronizer hub 5. This restricts the displacement and rotation of the synchronizer hub 5 in both the X and Y directions, completing the positioning and giving the synchronizer hub 5 its initial position relative to the conveying system and the comparator. At this point, the synchronizer hub 5 presses down on the displacement sensor 617, causing it to reach the second displacement amount and send a signal to the controller. The controller receives the signal. The rotary cylinder 8 is then shut off, and the fifth motor 902 is started to reset the rotary body 7. The controller then shuts off the fifth motor 902, stopping the rotary body 7. Simultaneously, the fourth motor 601 is started. The fourth motor 601 is connected to the third ball screw 606 via the third coupling 603, causing the conveying mechanism 6 to begin conveying the synchronizer hub 5 towards the comparator direction (Y-negative direction). When the slider panel 610 contacts the limit switch 605, it is detected by the sixth positioning sensor. The sixth positioning sensor sends a signal to the controller, which, upon receiving the signal, shuts off the fourth motor 601, stopping the synchronizer hub 5 and simultaneously starting the comparator.

[0078] When the comparator displays that the detection is complete, it sends a signal to the controller. Upon receiving the signal, the controller starts the fourth motor 601, causing the conveying mechanism 6 to move the synchronizer hub 5 away from the comparator until the synchronizer hub 5 is transported to its initial position. Then, the controller shuts off the fourth motor 601 and simultaneously starts the first motor 102 to vertically lower the clamping mechanism 4. When the clamping component 407 is horizontal with the synchronizer hub 5, it is detected by the second positioning sensor, which sends a signal to the controller. Upon receiving the signal, the controller shuts off the first motor 102, stopping the clamping mechanism 4 from descending. Simultaneously, the electric cylinder motor 306 is activated, which drives the arm via the electric cylinder rod 308. 406 clamps the synchronizer hub 5, which is detected by the pressure sensor. The pressure sensor sends a signal to the controller. After receiving the signal, the controller controls the electric cylinder motor 306 to shut down and simultaneously starts the first motor 102 to rotate 10 times, so that the clamping mechanism 4 rises vertically and the rising distance is greater than the radius of the synchronizer hub 5. Then the controller controls the first motor 102 to shut down, and the clamping mechanism 4 stops rising. At the same time, the third motor 301 is started to drive the rotating part 304 to complete the 180° rotation of the synchronizer hub 5. Then the controller controls the third motor 301 to shut down and starts the first motor 102 to make the clamping mechanism 4 descend vertically, so that the synchronizer hub 5 is placed back on the gear positioning post 607. The detection principle of the other end of the synchronizer hub 5 is the same as above.
