[0023] In order to make the purpose and advantages of the present utility model clearer, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present utility model, and does not strictly limit the scope of protection specifically claimed by the present utility model.
[0024] Such as Figure 1 , Figure 3 , Figure 4 and Figure 5As shown in the figure, a fixture for processing automobile exhaust pipes includes a processing table 10. On both sides of the upper end of the processing table 10, there are fixed bottom plates 11. A rotating mechanism 20 is assembled on the upper end of one bottom plate 11. A bracket 12 is arranged at the upper end of the rotating mechanism 20. One end of the bracket 12 is fixed with a support block 13. A lower clamping plate 14 is arranged at the upper end of the support block 13. One end of the bracket 12 away from the support block 13 is fixed with a first telescopic motor 15. And the output end of the first telescopic motor 15 penetrates through the upper end of the bracket 12. The upper end of the first telescopic motor 15 is fixed with an upper clamping plate 16.
[0025] In the above embodiment, when fixing the exhaust pipe, place the exhaust pipe on the lower clamping plate 14. When the first telescopic motor 15 starts to work, the exhaust pipe can be fixed by the upper clamping plate 16 and the lower clamping plate 14.
[0026] Furthermore, evenly arranged teeth 17 are arranged at the lower end of the upper clamping plate 16, and the material of the teeth 17 is rubber material.
[0027] In the above embodiment, the rubber teeth 17 can increase the friction between the upper clamping plate 16 and the clamped exhaust pipe, prevent the exhaust pipe from sliding or falling during the clamping process. At the same time, rubber has good shock absorption performance, which can effectively reduce the impact of the upper clamping plate 16 on the exhaust pipe during the clamping process and protect the surface of the exhaust pipe from being scratched or damaged.
[0028] Even further, a knob 18 is screwed at the lower end of the support block 13, and the knob 18 penetrates through the upper end of the support block 13 and is screwed to the lower clamping plate 14, and the lower clamping plate 14 is V-shaped.
[0029] In the above embodiment, the knob 18 penetrates through the upper end of the support block 13 and is screwed to the lower clamping plate 14. The position of the lower clamping plate 14 can be adjusted by rotating the knob 18, and the operation is simple. The lower clamping plate 14 is V-shaped, which can adapt to objects of different shapes and sizes, increasing the flexibility of use. At the same time, the V-shaped lower clamping plate 14 can better disperse the pressure and improve the bearing capacity.
[0030] Such as Figure 1 、 Figure 2 and Figure 6As shown in the figure, the rotating mechanism 20 includes a second telescopic motor 21, a moving block 22, a fixing plate 23, a rack 24, a first gear 25, a second gear 26, a first support plate 27, a second support plate 28, a first rotating rod 29 and a second rotating rod 30. At the upper end of the bottom plate 11, the second telescopic motor 21, the fixing plate 23, the first support plate 27 and the second support plate 28 are sequentially fixed from one side to the other side. The moving block 22 is fixed to the output end of the second telescopic motor 21. The rack 24 is slidably connected to the upper end of the fixing plate 23, and the moving block 22 is fixed to one side of the rack 24. The first rotating rod 29 is rotatably connected to one side of the first support plate 27. The first gear 25 is fixed to one side of the first rotating rod 29. The second rotating rod 30 penetrates through both sides of the first support plate 27, and the second rotating rod 30 is rotatably connected to the first support plate 27. A second gear 26 is fixed to one side of the second rotating rod 30 and above the first gear 25, and the first gear 25 and the second gear 26 are meshed. The other side of the second rotating rod 30 is rotatably connected to the second support plate 28. A rotating plate 32 is fixed to the outer side of the second rotating rod 30.
[0031] In the above embodiment, the second telescopic motor 21 can drive the moving block 22 to move. Secondly, since the moving block 22 is fixed to one side of the rack 24, the rack 24 moves on the fixing plate 23. Also, because the rack 24 and the first gear 25 are meshed, the first gear 25 is driven to rotate. Since the first gear 25 and the second gear 26 are meshed, the second gear 26 rotates. Also, because the second gear 26 is fixed to the second rotating rod 30, the second rotating rod 30 starts to rotate. The rotating plate 32 is fixed to the second rotating rod 30, and the rotating plate 32 starts to rotate. The rotation of the rotating plate 32 can make the fixed exhaust pipe rotate, so as to ensure that all parts of the exhaust pipe can be fully processed during the processing, and improve the processing accuracy.
[0032] Further, a T-shaped groove is formed inside the rack 24, and a T-shaped sliding rail is formed at the upper end of the fixing plate 23, and the T-shaped groove is adapted to the T-shaped sliding rail. Blocks are fixed to both ends of the upper end of the fixing plate 23.
[0033] In the above embodiment, the design of the T-shaped groove and the T-shaped sliding rail can make the connection between the rack 24 and the fixing plate 23 more stable, reduce the shaking during the movement, and improve the overall stability. The design of the blocks can prevent the rack 24 from slipping off the fixing plate 23 and protect the equipment from damage.
[0034] As Figure 1 shown, two square through holes are formed in the middle of the processing table 10 and at the lower end of the bottom plate 11, and the two square through holes are parallel to each other. Bolts 31 are fixed to both ends of the bottom plate 11, and the bolts 31 penetrate through the lower ends of the square through holes. The bottom plate 11 and the processing table 10 are fixedly connected by the bolts 31.
[0035] In the above-described embodiment, when fixing exhaust pipes of different sizes, the bottom plate 11 can be loosened by the bolts 31 and moved to a suitable position, and then fixed by the bolts 31, so as to fix exhaust pipes of different lengths.
[0036] The working principle of the present utility model is as follows:
[0037] The upper clamping plate 16 and the lower clamping plate 14 can fix the exhaust pipe. At the same time, the knob 18 can be loosened to adjust the position of the lower clamping plate 14 to adapt to the bent exhaust pipe. Meanwhile, when fixing exhaust pipes of different lengths, the bottom plate 11 can be loosened by the bolts 31 and moved to a suitable position, and then fixed by the bolts 31, so as to fix exhaust pipes of different lengths. When the exhaust pipe is fixed, the rotating mechanism 20 can be used to rotate the exhaust pipe, which can ensure that all parts can be fully processed during the processing, thereby improving the processing accuracy.
[0038] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices and operation methods not specifically described and explained in the present utility model, unless otherwise specified and limited, are implemented according to the conventional means in the art.
