Description

Technical Field

[0001] This application relates to the field of transmission device testing technology, and in particular to a gear and gear shaft testing and marking device. Background Technology

[0002] Gears and gear shafts are traditional transmission mechanisms widely used in moving equipment. The machining quality of gears and gear shafts affects the quality of mechanical transmission. Therefore, it is necessary to inspect the produced gears and gear shafts and mark qualified products.

[0003] Currently, in the production of gears and gear shafts, inspection and marking are usually treated as two separate processes. Gears and gear shafts need to be inspected sequentially before the marking process can be carried out. This makes the inspection and marking process of gears and gear shafts lengthy, resulting in low production efficiency of gears and gear shafts. Summary of the Invention

[0004] In order to improve the problem of the lengthy inspection and marking process of gears and gear shafts, which leads to low production efficiency of gears and gear shafts, this application provides a gear and gear shaft inspection and marking device.

[0005] The gear and gear shaft inspection and marking device provided in this application adopts the following technical solution: A gear and gear shaft inspection and marking device includes a gear inspection unit and a gear shaft inspection unit mounted on a support platform. The support platform is equipped with a marking unit for marking gears and gear shafts. The support platform is also equipped with a gear placement fixture and a gear shaft placement fixture. The gear inspection unit can inspect the gears on the gear placement fixture, and the gear shaft inspection unit can inspect the gear shafts on the gear shaft placement fixture. The support platform is equipped with a drive unit for driving the gear placement fixture or the gear shaft placement fixture to move to the marking unit.

[0006] By adopting the above technical solution, when inspecting and marking gears, the gears are placed on a gear placement fixture, and then inspected by a gear monitoring unit. After passing the inspection, the gear on the placement fixture is moved to the marking unit by a drive unit, where it is then marked. Similarly, when inspecting and marking gear shafts, the gear shafts are placed on a gear shaft placement fixture, and then inspected by a gear shaft inspection unit. After passing the inspection, the gear shaft on the placement fixture is moved to the marking unit by a drive unit, where it is then marked. This completes the inspection and marking process for both gears and gear shafts. By combining the inspection and marking processes for gears and gear shafts into one process, the inspection and marking process for gears and gear shafts is simplified, and the production efficiency of gears and gear shafts is improved.

[0007] In one specific implementation, the gear shaft detection unit includes a sample and a detection component. The detection component includes a first linear drive mechanism and a second detection ring. The first linear drive mechanism is disposed on the support platform, and the second detection ring is disposed on the first linear drive mechanism. The sample includes the first detection ring disposed on the first linear drive mechanism. The first detection ring is used to detect a standard gear shaft, and the second detection ring is used to detect a gear shaft placed on a gear shaft placement fixture. The first linear drive mechanism is used to drive the second detection ring to slide, so that the gear shaft is inserted into the second detection ring.

[0008] By adopting the above technical solution, when inspecting the gear shaft, the gear shaft is placed on the gear shaft placement fixture, and then the first linear drive mechanism drives the first detection ring to be fitted onto the standard gear shaft and the second detection ring to be fitted onto the gear shaft to be inspected. By comparing the gear shaft to be inspected with the standard gear shaft, it is possible to detect whether the gear shaft to be inspected is qualified.

[0009] In one specific implementation, the gear detection unit includes a standard component and a comparison component. The comparison component includes a fourth detection ring and a second linear drive mechanism. The second linear drive mechanism is disposed on the support platform, and the fourth detection ring is disposed on the second linear drive mechanism. The standard component includes a third detection ring for detecting a standard gear. The third detection ring is disposed on the second linear drive mechanism, and the second linear drive mechanism is used to drive the fourth detection ring to slide, so that the gear can be inserted into the fourth detection ring.

[0010] By adopting the above technical solution, when inspecting gears, the gears are placed on a gear placement fixture, and then the second linear drive mechanism drives the third detection ring to be fitted onto the standard gear and the fourth detection ring to be fitted onto the gear to be inspected. By comparing the gear to be inspected with the standard gear, it is possible to detect whether the gear to be inspected is qualified.

[0011] In one specific implementation, the gear shaft placement fixture includes a third linear drive mechanism, a first support plate, and a placement cylinder. The third linear drive mechanism is disposed on the support platform, the first support plate is disposed on the third linear drive mechanism, and the placement cylinder is disposed on the first support plate. The placement cylinder is for inserting the gear shaft, and the third linear drive mechanism is used to drive the first support plate to slide.

[0012] By adopting the above technical solution, when inspecting the gear shaft, the gear shaft is first placed in the placement cylinder, and then the third linear drive unit drives the first support plate to slide, so that the gear shaft slides from the side of the second detection ring to below the second detection ring, thereby improving the convenience of gear shaft inspection and placement.

[0013] In one specific implementation scheme, the gear placement fixture includes a fourth linear drive mechanism, a second support plate, and a support base. The fourth linear drive mechanism is disposed on the support platform, the second support plate is disposed on the fourth linear drive mechanism, and the support base is disposed on the second support plate. The support base is used for placing the gear, and the fourth linear drive mechanism is used to drive the second support plate to slide.

[0014] By adopting the above technical solution, when testing the gear, the gear is first placed on the support base, and then the fourth linear drive mechanism drives the second support plate to slide, so that the gear slides from the side of the fourth detection ring to below the fourth test ring, thereby improving the convenience of gear testing and placement.

[0015] In one specific implementation scheme, the marking unit includes a marking machine and a spatial position adjustment frame. The spatial position adjustment frame is disposed on the support platform, and the marking machine is disposed on the spatial position adjustment frame. The spatial position adjustment frame can drive the marking machine to move and rotate in spatial position.

[0016] By adopting the above technical solution, when marking the gear shaft, the spatial position adjustment frame drives the marking machine to mark the top end wall of the gear shaft. Then, the spatial position adjustment frame drives the marking machine to move to the peripheral side wall of the gear shaft for marking. When marking the gear, the spatial position adjustment frame drives the marking machine to move above the gear, and then the marking machine aligns with the gear for marking, thereby realizing the marking operation of the gear shaft and the gear.

[0017] In one specific implementation scheme, the drive unit includes a fifth linear drive mechanism and a gripper cylinder. The fifth linear drive mechanism is disposed on the support platform, and the gripper cylinder is disposed on the fifth linear drive mechanism. The first support plate is slidably disposed with the third linear drive mechanism, and the second support plate is slidably disposed with the fourth linear drive mechanism. The gripper cylinder is used to grip the first support plate or the second support plate. The fifth linear drive mechanism can drive the gripper cylinder to move to the marking machine. The first support plate is provided with a first pin cylinder, and the output shaft of the first pin cylinder is perpendicular to the sliding direction of the first support plate. The third linear drive mechanism is provided with a first fixing groove for the output shaft of the first pin cylinder to be inserted. The second support plate is provided with a second pin cylinder, and the output shaft of the second pin cylinder is perpendicular to the sliding direction of the second support plate. The fourth linear drive mechanism is provided with a second fixing groove for the output shaft of the second pin cylinder to be inserted.

[0018] By adopting the above technical solution, when the gear shaft passes inspection, the fifth linear drive mechanism drives the gripper cylinder to clamp the first support plate. At this time, the first pin cylinder pulls the output shaft out of the first fixed groove. Then, the fifth linear drive mechanism drives the first support plate to slide to the marking machine for marking. When the gear passes inspection, the fifth linear drive mechanism drives the gripper cylinder to clamp the second support plate. At this time, the second pin cylinder pulls the output shaft out of the second fixed groove. Then, the fifth linear drive mechanism drives the second support plate to slide to the marking machine for marking, thereby realizing the drive between the gear and the gear shaft for inspection and marking.

[0019] In one specific implementation scheme, the support platform is provided with an unloading rack, and the unloading rack is provided with a first electromagnet. The first electromagnet is positioned above the marking sliding trajectory of the gear shaft and is used to attract the gear shaft. The support platform is provided with a conveying unit and a feeding unit. The feeding unit is used to drive the first electromagnet to slide and move the gear shaft onto the conveying unit.

[0020] By adopting the above technical solution, when the first support plate slides to the marking machine, the feeding unit drives the first electromagnet to move above the gear shaft. When the gear shaft is finished marking and the first support plate returns, the first electromagnet is energized and attracts the gear shaft. Then, the feeding unit drives the first electromagnet to pull the gear shaft out of the placement cylinder and move it to the conveying unit. Then, the first electromagnet is de-energized, causing the gear shaft to fall onto the conveying unit and be transported away by the conveying unit. This allows qualified gear shafts and unqualified gear shafts to be unloaded separately, effectively preventing them from mixing together and making the unloading of qualified and unqualified gear shafts more accurate.

[0021] In one specific implementation, the feeding unit includes a conveyor belt, two rotating disks, and a drive screw. The two rotating disks are rotatably mounted on the support platform. The drive screw corresponds to each of the rotating disks and is coaxially fixed on the rotating disks. Both drive screws pass through the unloading frame and are threaded together. The two rotating disks are connected by the conveyor belt. The conveyor belt is provided with a stop block. The first support plate is provided with a second electromagnet for attracting and pushing the stop block.

[0022] By adopting the above technical solution, when the first support plate slides toward the marking machine, the second electromagnet attracts and pushes the stop block to slide, so that the conveyor belt drives the two rotating disks to rotate, the rotating disks drive the drive screw to rotate, and the drive screw drives the unloading rack to move downward, so that the electromagnet can move to the distance of the gear shaft. When the gear shaft finishes marking, the second electromagnet pulls the stop block to slide by attracting it, so that the drive screw reverses, so that the unloading rack moves upward, and so that the gear shaft is separated from the placement cylinder.

[0023] In one specific implementation, the conveying unit includes two sets of conveying mechanisms. A support frame is provided on the support platform. Both sets of conveying mechanisms are slidably mounted on the support frame. The two sets of conveying mechanisms are respectively located on both sides of the first electromagnet. Each set of conveying mechanisms is provided with a guide surface. The unloading frame can slide along the guide surface, so that the two sets of conveying mechanisms move away from each other. A telescopic spring is provided on the support frame. The telescopic spring corresponds to each conveying mechanism. The telescopic spring can push the conveying mechanism to slide below the gear shaft step.

[0024] By adopting the above technical solution, when the unloading rack moves down, it slides along the guide surface and pushes the two sets of conveying mechanisms away from each other. At this time, the telescopic spring contracts. When the electromagnet pulls the gear shaft to move above the conveying mechanism, the telescopic spring pushes the conveying mechanism to slide below the step of the gear shaft. At this time, the first electromagnet is de-energized, causing the step of the gear shaft to fall onto the conveying mechanism and then be transported away by the conveying mechanism. This achieves the unloading of qualified gear shafts and unqualified gears from different positions, making the unloading and separation of qualified and unqualified gear shafts more accurate.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. When inspecting and marking gears, the gears are placed on a gear placement fixture, and then the gear monitoring unit inspects the gears. After passing the inspection, the drive unit moves the gear on the gear placement fixture to the marking unit, where the marking unit marks the gear. When inspecting and marking gear shafts, the gear shafts are placed on a gear shaft placement fixture, and then the gear shaft inspection unit inspects the gear shafts. After passing the inspection, the drive unit moves the gear shaft on the gear shaft placement fixture to the marking unit, where the marking unit marks the gear shaft. This completes the inspection and marking of gears and gear shafts. By combining the inspection and marking processes of gears and gear shafts into one process, the inspection and marking process of gears and gear shafts is simplified, and the production efficiency of gears and gear shafts is improved. 2. After the gear shaft marking is completed and the first support plate returns, the first electromagnet is energized and attracts the gear shaft. Then, the feeding unit drives the first electromagnet to pull the gear shaft out of the placement cylinder and move it to the conveying unit. Then, the first electromagnet is de-energized, causing the gear shaft to fall onto the conveying unit and be transported away by the conveying unit. This achieves the unloading of qualified gear shafts and unqualified gear shafts from different positions, making the unloading and separation of qualified and unqualified gear shafts more accurate.

[0036] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0037] This application discloses a gear and gear shaft inspection and marking device.

[0038] Example 1 Reference Figure 1A gear and gear shaft inspection and marking device includes a gear inspection unit 2, a gear shaft inspection unit 3, a marking unit 4, a gear placement fixture 5, a gear shaft placement fixture 6, and a drive unit 7, all mounted on a support platform 1. The gear inspection unit 2 is capable of inspecting the gears on the gear placement fixture 5, the gear shaft inspection unit 3 is capable of inspecting the gear shafts on the gear shaft placement fixture 6, and the drive unit 7 is used to drive the gear placement fixture 5 and the gear shaft placement fixture 6 to move to the marking unit 4.

[0039] When inspecting and marking gears, the gears are placed on gear placement fixture 5, and then inspected by gear inspection unit 2. After passing the inspection, the gear on gear placement fixture 5 is moved to marking unit 4 by drive unit 7, and then marked by marking unit 4. When inspecting and marking gear shafts, the gear shafts are placed on gear shaft placement fixture 6, and then inspected by gear shaft inspection unit 3. After passing the inspection, the gear shaft on gear shaft placement fixture 6 is moved to marking unit 4 by drive unit 7, and then marked by marking unit 4. This completes the inspection and marking of gears and gear shafts. By combining the inspection and marking processes of gears and gear shafts into one process, the inspection and marking process of gears and gear shafts is simplified, and the production efficiency of gears and gear shafts is improved.

[0040] Reference Figure 1 , Figure 2 In this embodiment, the gear shaft detection unit 3 includes a sample 31 and a detection element 32. Two support rods 11 are fixedly mounted on the support platform 1, both of which are arranged vertically. The detection element 32 in this embodiment includes a first linear drive mechanism 321 and a second detection ring 322. The first linear drive mechanism 321 includes a first servo motor 3211, a first drive screw 3212, and a first sliding frame 3213. The first servo motor 3211 is fixedly mounted on the support rod 11, the first drive screw 3212 is coaxially fixedly mounted on the output shaft of the first servo motor 3211, and the first sliding frame 3213 is slidably mounted on the support rod 11. The first drive screw 3212 passes through the support rod 11. The first sliding frame 3213 is threadedly connected to the first sliding frame 3213. The first sliding frame 3213 slides vertically. The second detection ring 322 is fixedly mounted on the first sliding frame 3213. In this embodiment, the sample 31 includes the first detection ring 311. The first detection ring 311 is fixedly mounted on the side of the first sliding frame 3213 away from the second detection ring 322. The support platform 1 is provided with a placement platform 12 for placing a standard gear shaft. The placement platform 12 is located directly below the first detection ring 311. The first detection ring 311 is used to detect the standard gear shaft, and the second detection ring 322 is used to detect the gear shaft to be inspected. By comparing the two detection signals, it is possible to determine whether the gear shaft to be inspected is qualified or not.

[0041] Reference Figure 1 , Figure 2 The support platform 1 is equipped with a sliding platform 13. The gear shaft placement fixture 6 is located on one side of the sliding platform 13, below the second detection ring 322. In this embodiment, the gear shaft placement fixture 6 includes a third linear drive mechanism 61, a first support plate 62, and a placement cylinder 63. The third linear drive mechanism 61 includes a third servo motor 611, a third drive screw 612, and a third sliding frame 613. The support platform 1 is equipped with two guide rails 15. The third servo motor 611 is fixedly mounted on the two guide rails 15, and the third sliding frame 613 is slidably mounted on the guide rails 15. The third drive screw 612 is coaxially fixed on the output shaft of the third servo motor 611 and placed on the guide rail 15. The first support plate 62 is slidably mounted on the third sliding frame 613. The sliding direction of the first support plate 62 is perpendicular to the sliding direction of the third sliding frame 613. The sliding platform 13 is provided with a sliding groove 14 for the first support plate 62 to slide. The placement cylinder 63 is fixedly mounted on the first support plate 62. The top of the placement cylinder 63 is open. The gear shaft is inserted into the placement cylinder 63 from top to bottom. The shoulder of the gear shaft overlaps the placement cylinder 63.

[0042] When inspecting the gear shaft, the third servo motor 611 drives the first support plate 62 to slide to the side of the second detection ring 322. Then, the gear shaft to be inspected is inserted into the placement cylinder 63. The third servo motor 611 then moves the gear shaft to be inspected directly below the second detection ring 322. The first servo motor 3211 then moves the first detection ring 311 and the second detection ring 322 downwards, so that the standard gear shaft is inserted into the first detection ring 311 and the gear shaft to be inspected is inserted into the second detection ring 322. By comparing the detection signals between the first detection ring 311 and the second detection ring 322, it is possible to detect whether the gear shaft to be inspected is qualified, thus realizing the inspection of the gear shaft.

[0043] Reference Figure 2 , Figure 3 The first support plate 62 is provided with a first pin cylinder 64. The output shaft of the first pin cylinder 64 faces the third sliding frame 613. The third sliding frame 613 is provided with a first fixing groove 65 for the output shaft of the first pin cylinder 64 to be inserted. When the output shaft of the first pin cylinder 64 is inserted into the first fixing groove 65, the first support plate 62 and the third sliding frame 613 cannot slide.

[0044] Reference Figure 4In this embodiment, the marking unit 4 includes a marking machine 41 and a spatial position adjustment frame 42. The spatial position adjustment frame 42 is mounted on the support platform 1. In this embodiment, the spatial position adjustment frame 42 includes an X-axis adjustment mechanism 421, a Y-axis adjustment mechanism 422, and a Z-axis adjustment mechanism 423. The X-axis adjustment mechanism 421, the Y-axis adjustment mechanism 422, and the Z-axis adjustment mechanism 423 are all composed of a servo motor, a screw, and a sliding frame. In this embodiment, the X-axis adjustment mechanism 421 has the greatest degree of freedom. A rotating cylinder 43 is fixedly mounted on the sliding frame of the X-axis adjustment mechanism 421. A marking frame 44 is fixedly mounted on the output shaft of the rotating cylinder 43. The marking machine 41 is mounted on the marking frame 44. The marking machine 41 uses laser marking and can move above the sliding platform 13.

[0045] Reference Figure 4 In this embodiment, the drive unit 7 includes a fifth linear drive mechanism 71 and a gripper cylinder 72. The fifth linear drive mechanism 71 includes a fifth servo motor 711, a fifth drive screw 712, and a fifth sliding frame 713. A sliding bracket 714 is provided on the support platform 1. The sliding bracket 714 is arranged along the length direction of the sliding platform 13. The fifth servo motor 711 is fixedly mounted on the sliding bracket 714. The fifth sliding frame 713 is slidably mounted on the sliding bracket 714. The fifth drive screw 712 is coaxially fixedly mounted on the output shaft of the fifth servo motor 711. The fifth drive screw 712 passes through the fifth sliding frame 713 and is threadedly connected to the fifth sliding frame 713. The gripper cylinder 72 is fixedly mounted on the fifth sliding frame 713. A clamping block 73 is provided on the first support plate 62. The two output shafts of the gripper cylinder 72 can clamp the clamping block 73.

[0046] After the gear shaft inspection is completed, the first servo motor 3211 drives the first inspection ring 311 and the second inspection ring 322 to move upward. When the gear shaft is unqualified, the third servo motor 611 drives the gear shaft to slide laterally, and then the gear shaft is unloaded manually. When the gear shaft is qualified, the output shaft of the first pin cylinder 64 is driven to be pulled out of the first fixing groove 65. Then, the fifth servo motor 711 drives the gripper cylinder 72 to move and clamp the clamping block 73. Then, the fifth servo motor 711 drives the first support plate 62 to slide up and down through the gripper cylinder 72. The gear shaft is moved into the sliding groove 14 of the platform 13 and then moved to the marking machine 41. The marking machine 41 is then adjusted by the spatial position adjustment frame 42 so that the marking machine 41 can first mark the end face of the gear shaft and then mark the side face of the gear shaft. After the marking is completed, the fifth servo motor 711 drives the first support plate 62 to slide onto the third sliding frame 613, and then unloads from the side of the second detection ring 322. This allows the detection and marking of the gear shaft to be carried out in one process, which simplifies the detection and marking process of the gear shaft and improves the detection and marking efficiency of the gear shaft.

[0047] Reference Figure 1 , Figure 5 In this embodiment, the gear detection unit 2 includes a standard component 21 and a comparison component 22. The standard component 21 includes a third detection ring 211 for detecting a standard gear. The comparison component 22 includes a fourth detection ring 221 and a second linear drive mechanism 222. The second linear drive mechanism 222 includes a second servo motor 2221, a second drive screw 2222, and a second sliding frame 2223. The second servo motor 2221 is mounted on another support rod 11. The second sliding frame 2223 is slidably mounted on the support rod 11 and slides along the length of the support rod 11. The second drive screw 2222 is coaxially fixed to the second servo motor 2221. On the output shaft of 21, the third detection ring 211 and the fourth detection ring 221 are both fixedly mounted on the second sliding frame 2223. A bearing plate 223 is fixedly mounted on the support rod 11. The bearing plate 223 is located between the third detection ring 211 and the fourth detection ring 221. The third detection ring 211 is positioned above the bearing plate 223, and the fourth detection ring 221 is positioned below the bearing plate 223. A standard gear is placed on the bearing plate 223. The third detection ring 211 is used to detect the standard gear, and the fourth detection ring 221 is used to detect the gear to be tested. The signal generated by the third detection ring 211 and the fourth detection ring 221 determines whether the gear to be tested is qualified.

[0048] Reference Figure 4 , Figure 5 In this embodiment, the gear placement fixture 5 includes a fourth linear drive mechanism 51, a second support plate 52, and a support base 53. The fourth linear drive mechanism 51 includes a fourth servo motor 511, a fourth drive screw 512, and a fourth sliding frame 513. A guide frame 16 is provided on the support platform 1, positioned on one side of the sliding platform 13 and below the fourth detection ring 221. The fourth servo motor 511 is fixedly mounted on the guide frame 16, and the fourth sliding frame 513 is slidably mounted on the guide frame 16. The fourth drive screw 512 is coaxially fixedly mounted on the fourth servo motor 511. On the output shaft of machine 511, the fourth drive screw 512 passes through the fourth sliding frame 513 and is threadedly connected to the fourth sliding frame 513. The second support plate 52 is slidably mounted on the fourth sliding frame 513. The sliding direction of the second support plate 52 is perpendicular to the sliding direction of the fourth sliding frame 513. The second support plate 52 is also provided with a clamping block 73 for clamping by the gripper cylinder 72. The gripper cylinder 72 can drive the second support plate 52 to slide from the fourth sliding frame 513 onto the sliding platform 13. The support seat 53 is fixedly mounted on the second support plate 52. The support seat 53 is provided with a positioning pin 631.

[0049] Reference Figure 5 , Figure 6A second pin cylinder 54 is fixedly installed on the second support plate 52. The output shaft of the second pin cylinder 54 is set in the direction of the fourth sliding frame 513. The fourth sliding frame 513 is provided with a second fixing groove 55 for the output shaft of the second pin cylinder 54 to be inserted.

[0050] When inspecting the gear, the gear is first placed on the support base 53. For gears with larger diameters, there are usually through holes in the circumference of the gear to reduce the weight of the gear. The positioning pin 631 is inserted into the through hole of the gear to position the gear, which can effectively prevent the marking machine 41 from marking the gear through hole position during marking, resulting in an incomplete mark.

[0051] Then, the fourth servo motor 511 drives the gear to be inspected to move below the third detection ring 211. Then, the second servo motor 2221 drives the third detection ring 211 and the fourth detection ring 221 to move down, so that the standard gear is inserted into the third detection ring 211 and the gear to be inspected is inserted into the fourth detection ring 221. Then, by comparing the signals of the third detection ring 211 and the fourth detection ring 221, it is determined whether the gear to be inspected is qualified. After the gear is qualified, the fifth servo motor 711 drives the gripper cylinder 72 to clamp the clamping block 73 on the second support plate 52, and then drives the second support plate 52 to move to the marking machine 41. Then, the marking machine 41 marks the gear, so that the gear inspection and marking are carried out in the same process, which simplifies the gear inspection and marking process and improves the gear inspection and marking efficiency.

[0052] The implementation principle of Example 1 is as follows: The gear is placed on the gear placement fixture 5, and then the gear is inspected by the gear inspection unit 2. After passing the inspection, the gear on the gear placement fixture 5 is driven by the drive unit 7 to move to the marking unit 4, and then the gear is marked by the marking unit 4. When inspecting and marking the gear shaft, the gear shaft is placed on the gear shaft placement fixture 6, and then the gear shaft is inspected by the gear shaft inspection unit 3. After passing the inspection, the drive unit 7 drives the gear shaft on the gear shaft placement fixture 6 to move to the marking unit 4, and then the gear shaft is marked by the marking unit 4. Thus, the inspection and marking of the gear and gear shaft are completed. By combining the inspection and marking processes of the gear and gear shaft into one process, the inspection and marking process of the gear and gear shaft is simplified, and the production efficiency of the gear and gear shaft is improved.

[0053] Example 2 Reference Figure 7 , Figure 8The difference between this embodiment and Embodiment 1 is that the support platform 1 is provided with an unloading rack 81, and the unloading rack 81 is provided with a first electromagnet 82. The first electromagnet 82 is positioned above the marking sliding trajectory of the gear shaft and is used to attract the gear shaft. The support platform 1 is provided with a conveying unit 83 and a feeding unit 84. The feeding unit 84 is used to drive the first electromagnet 82 to slide and move the gear shaft onto the conveying unit 83. In this embodiment, the feeding unit 84 includes a conveyor belt 841, two rotating disks 842, and a drive screw 843. The support platform 1 is provided with a bracket 844, and the two rotating disks 842 are rotatably mounted on the bracket 844 at intervals. Along the length of the sliding platform 13, there is one drive screw 843, which is coaxially fixed on the rotating disk 842. The other end of the drive screw 843 passes through the unloading rack 81 and is threadedly connected to the unloading rack 81. The conveyor belt 841 passes around the two rotating disks 842 and is taut. The conveyor belt 841 is provided with a stop block 845. The first support plate 62 is provided with a second electromagnet 846. The stop block 845 is made of iron and extends to the sliding track of the second electromagnet 846. When the first support plate 62 drives the gear shaft to perform marking, the second electromagnet 846 can fit against the stop block 845 and attract the stop block 845.

[0054] Reference Figure 7 , Figure 8 and Figure 9In this embodiment, the conveying unit 83 includes two sets of conveying mechanisms 831, each of which is a conveyor belt 841 mechanism. A support frame 832 is provided on the support platform 1. Each conveyor belt 841 mechanism is connected to the support frame 832 via a connecting rod 833. The two sets of conveying mechanisms 831 are respectively arranged on both sides of the first electromagnet 82. Each connecting rod 833 is slidably sleeved on the support frame 832 via a collar. Each support rod 11 is provided with a base block 834. Guide surfaces 835 are provided on opposite sides of the two base blocks 834. Part of the unloading rack 81 is located between the two guide surfaces 835. The distance between the two guide surfaces 835 gradually decreases from top to bottom. The unloading rack 81 can slide along the guide surfaces 835, so that the two connecting rods 833 and the conveying mechanism 831 interact with each other. Two telescopic springs 836 are provided on the support frame 832, and each telescopic spring 836 corresponds to a connecting rod 833. The telescopic spring 836 is located on the side of one connecting rod 833 away from the other connecting rod 833. One end of the telescopic spring 836 abuts against the connecting rod 833, and the other end abuts against the support frame 832. Two guide rods 837 are provided on the support platform 1. One end of each guide rod 837 extends to the conveying mechanism 831. The distance between the two guide rods 837 is less than the diameter at the shoulder of the gear shaft, so that the gear shaft can be attached to the two guide rods 837 by the shoulder. The height of the two guide rods 837 gradually decreases from one end of the conveying mechanism 831 to the other end. The part of the guide rod 837 that overlaps with the sliding trajectory of the gear shaft is above the gear shaft.

[0055] The implementation principle of Example 2 is as follows: When the gear shaft passes the inspection, the first support plate 62 drives the gear shaft to slide towards the marking machine 41. At this time, during the sliding process of the first support plate 62, the push block is attracted by the second electromagnet 846 and pushes the stop block 845 to move. The push block drives the rotating disk 842 to rotate through the conveyor belt 841. The rotating disk 842 drives the drive screw 843 to rotate. The drive screw 843 drives the unloading rack 81 to move down. The unloading rack 81 drives the first electromagnet 82 to move down to above the gear shaft. During the downward movement of the unloading rack 81, the unloading rack 81 slides along the guide surface 835 and pushes the two conveying mechanisms 831 away from each other. At this time, the telescopic spring 836 is in a compressed state.

[0056] After the gear shaft is marked, the first support plate 62 drives the gear shaft to slide towards the gear shaft inspection station. The first electromagnet 82 is energized and attracts the gear shaft. At this time, the first support plate 62 attracts the stop block 845 through the second electromagnet 846, pulling the conveyor belt 841 to reverse, causing the drive screw 843 to drive the unloading rack 81 to move upward. The first electromagnet 82 pulls the gear shaft upward. The two conveying mechanisms 831 move closer to each other under the push of the telescopic spring 836. When the shoulder of the gear shaft moves to the conveying mechanism 83... When the gear shaft is above the first electromagnet 82, the distance between the two conveying mechanisms 831 is less than the diameter at the shoulder of the gear shaft. At this time, the first electromagnet 82 is de-energized, and the gear shaft falls onto the two conveying mechanisms 831. The conveying mechanisms 831 transport the gear shaft to the two guide rods 837, and then slide along the guide rods 837 to unload the gear shaft. This allows qualified gear shafts and unqualified gear shafts to be unloaded from different places, thus achieving more accurate separation of qualified and unqualified gear shafts during unloading.

[0057] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
