DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; it is obvious that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0029] Reference Figure 1-Figure 5 , a clamping mechanism for the production of motor vehicle parts, comprising a workbench 1, wherein an adjustment component is provided inside the workbench 1;

[0030] The number of adjustment components is set to two groups, each group of adjustment components includes a connecting rod 9, and the top of each connecting rod 9 is fixedly connected to a support plate 10. A motor 3 is provided on one side of a group of adjustment components, and the motor 3 is used to drive the two connecting rods 9 and the two support plates 10 for angle adjustment.

[0031] Reference Figure 1-Figure 5 Each set of adjustment components also includes a worm 4. Two fixed plates 19 are fixedly connected to both sides of the interior of the workbench 1. A second rotating rod 18 is rotatably connected to the interior of each of the two fixed plates 19. Each worm 4 is fixedly connected to the corresponding second rotating rod 18. A second rotating rod 18 is fixedly connected to the output end of the motor 3. A transmission wheel 5 is fixedly connected to one side of the outer wall of the two second rotating rods 18. The two transmission wheels 5 are connected by belts. A support frame 6 is fixedly connected to both sides of each two fixed plates 19. The interior of each support frame 6 is rotatably connected to a first rotating rod 8. The outer wall of each first rotating rod 8 is fixedly connected to a worm gear 7. Each worm gear 7 is meshed with the corresponding worm 4. Each connecting rod 9 is fixedly connected to the outer wall of the corresponding first rotating rod 8. A clamping unit is provided on the top of each support plate 10.

[0032] The angle of the accessory 2 (for example, the accessory 2 is a bogie for EMU production) can be adjusted according to production requirements through the adjustment component. The specific operation method is: first start the motor 3, and the output end of the motor 3 drives a second rotating rod 18 connected to it to rotate. The second rotating rod 18 drives the worm 4 fixedly connected thereto to rotate. At the same time, through the transmission action of the transmission wheel 5 and the belt, the other second rotating rod 18 rotates synchronously, thereby driving the other worm 4 to rotate. As the worm 4 rotates, the worm gear 7 engaged with it starts to rotate, and the worm gear 7 drives the first rotating rod 8 to rotate in the support frame 6. The first rotating rod 8 then drives the connecting rod 9 and the support plate 10 fixed to the top of the connecting rod 9 to rotate. The clamping unit arranged on the top of the support plate 10 and the clamped accessory 2 through two sets of adjustment components can adjust the angle according to production requirements.

[0033] By adjusting the component, the angle of the accessory 2 can be flexibly adjusted according to different production needs, so that the accessory 2 can be processed in multiple directions and angles in the same production process, adapting to various complex production processes, increasing the flexibility and diversity of production, and the precise angle adjustment function helps to ensure that the accessory 2 is always in the best processing position and angle during the processing, reducing the errors caused by multiple clamping and adjustment, thereby significantly improving the processing accuracy, ensuring the high-quality production of the EMU accessory 2, avoiding the time wasted due to frequent disassembly and reinstallation of the accessory 2, shortening the production cycle, improving the work efficiency on the production line, and helping to quickly complete production tasks.

[0034] Reference Figure 3 and Figure 5 The clamping unit includes a moving block 12, and the number of moving blocks 12 is set to two. A knob 13 is provided at the top of each moving block 12. The interior of each moving block 12 is rotatably connected to a positive and negative threaded rod 14. Each positive and negative threaded rod 14 passes through the corresponding moving block 12 and is fixedly connected to the knob 13. The outer walls on both sides of each positive and negative threaded rod 14 are threadedly connected to two adjusting blocks 16. A limiting hole 17 is provided on one side of each moving block 12. Each positive and negative threaded rod 14 is slidably connected to the corresponding limiting hole 17. A clamping block 15 is fixedly connected to one side of each adjusting block 16.

[0035] The accessory 2 can be fixed by the clamping unit. The specific operation method is to first rotate the knob 13, and the knob 13 drives the forward and reverse threaded rods 14 to rotate inside the moving block 12. Since the threads on both sides of the forward and reverse threaded rods 14 are in opposite directions, as the forward and reverse threaded rods 14 rotate, the two adjustment blocks 16 threadedly connected thereto will move toward or away from each other along the forward and reverse threaded rods 14 under the restriction of the limiting holes 17. When it is necessary to fix the accessory 2, the two adjustment blocks 16 drive the clamping blocks 15 to move toward each other until the clamping blocks 15 are tightly fitted on both sides of the accessory 2, firmly fixing the accessory 2; when it is necessary to loosen the accessory 2, rotate the knob 13 in the opposite direction, so that the two adjustment blocks 16 drive the clamping blocks 15 to move away from each other, thereby releasing the clamping of the accessory 2.

[0036] The clamping unit can provide a uniform and stable clamping force, ensuring that the accessory 2 will not be displaced or loosened during the processing, improving the accuracy and stability of the processing, increasing the versatility and applicability of the clamping unit, and being able to meet the clamping requirements of various EMU accessories 2.

[0037] Reference Figure 3Two groups of slide grooves 11 are provided on the top of each support plate 10, and the number of each group of slide grooves 11 is set to multiple. Each moving block 12 is slidably connected to the corresponding slide groove 11. Since the inner wall of the slide groove 11 is provided with a friction block, the moving block 12 can be prevented from sliding on its own without external force intervention, ensuring the stable position of the moving block 12 and the clamping block 15 thereon, thereby ensuring stability and reliability when clamping the accessory 2, and ensuring processing accuracy.

[0038] Reference Figure 1-Figure 3 Each clamping block 15 is provided with a slot on one side close to the accessory 2. The number of the slots is set to multiple, which can increase the friction force and make the accessory 2 less likely to slide or deflect during the clamping process.

[0039] Working principle: First, start the motor 3. The output end of the motor 3 drives a second rotating rod 18 connected to it to rotate. The second rotating rod 18 drives the worm 4 fixed thereon to rotate. At the same time, through the transmission action of the transmission wheel 5 and the belt, the other second rotating rod 18 rotates synchronously, thereby driving the other worm 4 to rotate. As the worm 4 rotates, the worm gear 7 engaged with it begins to rotate. The worm gear 7 drives the first rotating rod 8 to rotate in the support frame 6. The first rotating rod 8 then drives the connecting rod 9 and the support plate 10 fixed to the top of the connecting rod 9 to rotate. The clamping unit arranged on the top of the support plate 10 and the clamped accessory 2 through two sets of adjustment components can adjust the angle according to production requirements.

[0040] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
