Description

Technical Field

[0001] The utility model belongs to the technical field of exhaust pipe processing, and more specifically, relates to a processing jig for truck exhaust pipes. Background Art

[0002] The exhaust pipe is the pipe in a vehicle's exhaust system responsible for channeling exhaust gases from the engine. During engine operation, exhaust gases are discharged through the pipe and then, after treatment with a muffler and other equipment, released into the atmosphere. The exhaust pipe's primary function is to ensure that exhaust gases are accurately directed out of the vehicle and, through sound absorption and purification, minimize any harm to the environment and human health.

[0003] Based on the above, the inventors found that the following problems exist: during processing, the exhaust pipe needs to be fixed and then polished to ensure the flatness of the inside and outside. In general fixing devices, the lower support components are not convenient for width adjustment. If different models of exhaust pipes are fixed, the diameter of the exhaust pipe is large, which will result in only a small part of the lower part of the exhaust pipe being in contact with the support component, and then fixed by the upper fixing parts. This cannot provide a more stable fixing structure, which is not conducive to improving the overall stability.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a truck exhaust pipe processing jig is provided to achieve a more practical purpose. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a truck exhaust pipe processing jig to solve the problem that when fixing exhaust pipes of different models, the diameter of the exhaust pipe is large, which will result in only a small part of the lower part of the exhaust pipe being in contact with the supporting component, and then being fixed by the upper fixing parts, which cannot provide a more stable fixing structure.

[0006] The purpose and effect of the truck exhaust pipe processing jig of the utility model are achieved by the following specific technical means:

[0007] A truck exhaust pipe processing jig includes a base, a lower movable platform is provided on the base, a limiting column is installed on the lower movable platform, the lower movable platform is movably connected to the upper movable platform through the limiting column, two lower movable fixed blocks are provided on the inner side of the lower movable platform, the two lower movable fixed blocks are connected by a rotating rod, a set of two-way threads are opened on the rotating rod, the rotating rod is connected to the two lower movable fixed blocks through the two-way threads, a fixing plate is installed on the top of the limiting column, the middle part of the fixing plate is threadedly connected to a pushing stud through a nut, and the lower part of the pushing stud is rotatably connected to the middle part of the upper movable platform.

[0008] Furthermore, two upper movable fixed blocks are provided on the inner side of the upper movable platform, and the two upper movable fixed blocks are movably connected by a limit rod. The inner sides of the two upper movable fixed blocks and the two lower movable fixed blocks are provided with oblique anti-slip surfaces.

[0009] Furthermore, a boss is installed on the side of the lower movable fixed block, and a limit block is installed on the side of the upper movable fixed block. The boss and the limit block are arranged opposite to each other in the upper and lower directions. A column is installed on the boss, and the column passes through the limit block.

[0010] Furthermore, one end of the rotating rod is connected to a first driving motor, an output end of the first driving motor is connected to the rotating rod, and the first driving motor is connected to the lower moving platform.

[0011] Furthermore, a bidirectional screw is rotatably installed on the inner side of the base, a connecting piece is installed on the middle part of the lower surface of the lower movable platform, and the bidirectional screw is threadedly connected to the connecting piece through a set of bidirectional threads.

[0012] Furthermore, one end of the bidirectional screw is connected to a second drive motor, an output end of the second drive motor is connected to the bidirectional screw, and the second drive motor is connected to the base.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In the utility model, the rotating rod can be driven to rotate by the first driving motor. When the rotating rod rotates, the two lower movable fixed blocks can be driven to move synchronously inward or outward through the bidirectional thread until they are adapted to the diameter of the exhaust pipe. Then the pushing stud is rotated, and at this time, the lower end of the stud is pushed downward by cooperating with the nut, which can push the upper movable platform downward. At this time, the oblique anti-slip surface on the upper movable fixed block can be driven to gradually contact the exhaust pipe. By fixing the exhaust pipe at all four circumferences, the overall stability can be improved.

[0015] In the utility model, the bidirectional screw can be driven to rotate by starting the second drive motor. When the bidirectional screw rotates, the two lower moving platforms can be driven to move inward or outward at the same time through the thread, which is convenient for fixing exhaust pipes of different lengths.
