Description
Technical Field
[0001] The utility model belongs to the technical field of exhaust pipe processing, and in particular relates to a clamping mechanism for processing vehicle exhaust pipes. Background Art
[0002] Auto parts are the various units that constitute the overall processing of auto parts and the products that serve the processing of auto parts. Automotive exhaust pipes are automotive parts. The exhaust pipe is part of the engine exhaust system. The exhaust system mainly includes the exhaust manifold, exhaust pipe and muffler. Generally, the three-stage catalytic converter for controlling engine pollutant emissions is also installed in the exhaust system. The exhaust pipe generally includes the front exhaust pipe and the rear exhaust pipe. In the process of processing the exhaust pipe, a clamping mechanism is needed to clamp and fix the exhaust pipe, which can facilitate the user to perform processing operations on the exhaust pipe in a fixed position.
[0003] At present, most of the existing exhaust pipe clamping mechanisms adopt a fixed design, that is, the opening size of the clamping mechanism is fixed and can only adapt to an exhaust pipe of a specific size. Although this design is simple, different clamping mechanisms need to be replaced for exhaust pipes of different sizes, which increases production costs and operational complexity. Secondly, the existing exhaust pipe processing fixtures only perform a single clamping on the outside or inside of the exhaust pipe, resulting in uneven force inside and outside the exhaust pipe during processing. When impacted by external force, the exhaust pipe is prone to shaking, thereby affecting the processing effect. Based on the above problems, this application document proposes a clamping mechanism for vehicle exhaust pipe processing to improve the above problems. Utility Model Content

[0023] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.
[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, a clamping mechanism for processing vehicle exhaust pipes includes a base plate 10, and a first support frame 11, a sliding plate 25 and a support plate 15 are fixed to the upper end of the base plate 10 in sequence from one side to the other side, a round rod 26 is fixed to the side of the sliding plate 25 close to the support plate 15, a moving block 27 is slidably connected to the outer side of the round rod 26, a support seat 28 is fixed to the side of the round rod 26 away from the sliding plate 25, and a plurality of evenly arranged first fixed blocks 29 are fixed to the side of the support seat 28 close to the moving block 27, a first connecting rod 30 is hinged between two first fixed blocks 29, an evenly arranged second fixed block 31 is fixed to the outer side of the moving block 27, a second connecting rod 32 is hinged between the two second fixed blocks 31, and the second fixed block 31 and the second connecting rod 32 are hingedly connected by a locating pin 33.
[0025] In the above embodiment, when the movable block 27 moves, it pushes the second connecting rod 32 to rotate, and the second connecting rod 32 rotates around the second fixed block 31. At the same time, the first connecting rod 30 rotates around the first fixed block 29. Because the first connecting rod 30 and the second connecting rod 32 are hingedly connected by the positioning pin 33, when the movable block 27 moves, the positioning pin 33 can support the inner side of the exhaust pipe.
[0026] Furthermore, the positioning pin 33 is in an I-shape, and the material of both ends of the positioning pin 33 is rubber material.
[0027] In the above embodiment, both ends of the positioning pin 33 can clamp the inside of the exhaust pipe, and the rubber material can prevent damage to the inside of the exhaust pipe.
[0028] Furthermore, a load-bearing plate 34 is fixed to the side of the sliding plate 25 away from the support plate 15, a second support frame 35 is fixed to the upper end of the load-bearing plate 34, a third telescopic motor 36 is fixed to one side of the second support frame 35, and the output end of the third telescopic motor 36 passes through both sides of the second support frame 35 and extends to the side of the sliding plate 25 close to the support plate 15, a baffle 37 is fixed to the output end of the third telescopic motor 36, and the baffle 37 is slidably connected to the outer side of the circular rod 26.
[0029] In the above embodiment, when the third telescopic motor 36 is working, the output end of the third telescopic motor 36 drives the baffle 37 to move, the baffle 37 can push the moving block 27, and the round rod 26 is slidably connected to the baffle 37.
[0030] Furthermore, a support block 16 is fixed to one end of the support plate 15, a lower clamping plate 17 is fixed to the upper end of the support block 16, a second telescopic motor 18 is fixed to the upper end of the support plate 15, an output end of the second telescopic motor 18 passes through the upper end of the support plate 15, and an upper clamping plate 19 is fixed to the output end of the second telescopic motor 18.
[0031] In the above embodiment, when the second telescopic motor 18 is working, the upper clamping plate 19 moves downward, and the upper clamping plate 19 and the lower clamping plate 17 can clamp the outer side of the exhaust pipe. By adjusting the output end of the second telescopic motor 18, the distance between the upper clamping plate 19 and the lower clamping plate 17 can be easily adjusted to meet the needs of exhaust pipes of different sizes.
[0032] Furthermore, the upper end of the lower clamping plate 17 is provided with uniformly arranged teeth 20 , and the material of the teeth 20 is rubber.
[0033] In the above embodiment, the rubber teeth 20 have good anti-slip properties, which can effectively prevent the exhaust pipe from sliding or falling on the lower clamping plate 17. The rubber material has good shock-absorbing properties, which can effectively reduce the vibration of the exhaust pipe on the lower clamping plate 17 and protect the exhaust pipe from damage.
[0034] like Figure 1 , Figure 2 and Figure 5 As shown, the bottom plate 10 is provided with two parallel grooves at the lower end of the sliding plate 25, and two sliding blocks 24 are fixed to the lower end of the sliding plate 25. The two sliding blocks 24 are slidably connected in the two parallel grooves, and the two sliding blocks 24 are adapted to the two grooves. A first telescopic motor 12 is fixed to the side of the first support frame 11 away from the sliding plate 25, and the output end of the first telescopic motor 12 is fixedly connected to the side of the sliding plate 25 close to the first support frame 11.
[0035] In the above embodiment, when the first telescopic motor 12 is working, it drives the sliding plate 25 to move. A sliding block 24 is fixed to the lower end of the sliding plate 25. The sliding block 24 slides in the groove opened in the bottom plate 10. The cooperation between the sliding block 24 and the groove makes the sliding plate 25 more stable during the movement and less likely to deviate or shake.
[0036] The working principle of the utility model is:
[0037] During operation, the first telescopic motor 12 drives the sliding plate 25 to a suitable position. At this time, the third telescopic motor 36 pushes the baffle 37, and the baffle 37 pushes the moving block 27 to move. The moving block 27 can move the positioning pin 33 outward. At the same time, because the two ends of the positioning pin 33 are made of rubber material, the rubber material at both ends of the positioning pin 33 clamps the inside of the exhaust pipe from the inside. At the same time, the second telescopic motor 18 starts to work, and the second telescopic motor 18 drives the upper clamping plate 19 to move downward. At the same time, the upper clamping plate 19 and the lower clamping plate 17 can clamp the outside of the exhaust pipe.
[0038] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
