Technical Field
[0001] This application relates to the technical field of exhaust pipe manufacturing, and in particular to an auxiliary welding fixture for exhaust pipe manufacturing. Background Technology
[0002] like Figure 1 The exhaust pipe 8 shown includes a pipe 81 and a base 82. The pipe is vertically welded to the middle of the base, and the other end of the pipe has a flange bend 811. In the existing welding process, two workers are required to place the pipe vertically in the middle of the base, and then lift the pipe to a certain height and support it to prevent the pipe end from being too long inside the base. After that, the welder welds the pipe to the base.
[0003] This method not only results in high labor intensity for workers, but also leads to inconsistent pipe lengths due to manual adjustment, affecting product quality and reducing production efficiency.
[0004] Therefore, there is an urgent need to develop a tooling that can assist workers in welding and processing exhaust pipes. Utility Model Content

A pipe positioning mechanism and a base positioning mechanism are mounted on the frame. The pipe positioning mechanism includes a winch, a fixed frame, a lifting frame, a positioning clamping assembly, and an auxiliary support assembly. The fixed frame is vertically fixed to the frame. The lifting frame is slidably connected to the side of the fixed frame. The winch is fixed to the frame and is used to drive the lifting frame to move up and down. The positioning clamping assembly is disposed on the side of the lifting frame. The auxiliary support assembly is correspondingly disposed at the bottom of the positioning clamping assembly and is mounted on the fixed frame. The seat positioning mechanism includes a base and a three-jaw chuck. The base is fixed on the frame, and the three-jaw chuck is fixed on the base. The three-jaw chuck is correspondingly disposed at the bottom of the auxiliary support component.
[0007] The positioning and clamping assembly includes a connecting frame, a positioning seat, and a quick clamp. The connecting frame is vertically fixed on the lifting frame, the positioning seat is fixed at the end of the connecting frame, the positioning seat includes a vertical part and a horizontal part, the surface of the horizontal part is provided with an arc-shaped placement groove, and the quick clamp is fixed at the top of the vertical part.
[0008] The auxiliary support assembly includes a support frame and a support block. The support frame is fixed to the side of the fixed frame, and the support block is fixed to the end of the support frame.
[0009] Preferably, in order to facilitate the adjustment of the pipe's position in the vertical direction by the staff, a scale strip is provided on the side wall of the fixing frame.
[0010] Preferably, the bottom of the frame is provided with casters, and the four corners of the frame are threaded with adjusting screws, the bottom of which is rotatably connected to a support pad.
[0011] By adopting the above technical solution and installing casters, the equipment can be pushed to a designated position without the use of auxiliary welding fixtures, thereby freeing up workshop space.
[0012] In summary, this application includes at least one of the following beneficial technical effects: The auxiliary welding fixture for exhaust pipe production, by setting up a positioning clamping assembly and an auxiliary support assembly, can suspend and fix the pipe in a vertical state, and lower the pipe into the base body using a winch and keep it stationary. At this time, welders can easily weld the connection between the pipe and the base body, and the welding efficiency is high and the welding effect is good, greatly improving production efficiency.

[0017] The following is in conjunction with the appendix Figure 2-3 This application will be described in further detail below.
[0018] This application discloses an auxiliary welding fixture for the production of exhaust pipes. (Refer to...) Figure 2-3The system includes a frame 1, on which a pipe positioning mechanism 2 and a base positioning mechanism 3 are mounted. The pipe positioning mechanism 2 includes a winch 21, a fixed frame 22, a lifting frame 23, a positioning clamping assembly 24, and an auxiliary support assembly 25. The fixed frame 22 is vertically fixed to the frame 1, and the lifting frame 23 is slidably connected to the side of the fixed frame 22. The winch 21 is fixed to the frame 1 and is used to drive the lifting frame 23 to move up and down. The positioning clamping assembly 24 is located on the side of the lifting frame 23, and the auxiliary support assembly 25 is correspondingly located at the bottom of the positioning clamping assembly 24 and is mounted on the fixed frame 22.
[0019] The positioning and clamping assembly 24 includes a connecting frame 241, a positioning seat 242, and a quick clamp 243. The connecting frame 241 is vertically fixed to the lifting frame 23, and the positioning seat 242 is fixed to the end of the connecting frame 241. The positioning seat 242 includes a vertical part and a horizontal part, and an arc-shaped placement groove 2421 is formed on the surface of the horizontal part. The quick clamp 243 is fixed to the top of the vertical part.
[0020] The auxiliary support assembly 25 includes a support frame 251 and a support block 252. The support frame 251 is fixed to the side of the fixed frame 22, and the support block 252 is fixed to the end of the support frame 251.

[0022] To facilitate the adjustment of the pipe's vertical position by staff, a scale strip 7 is provided on the side wall of the fixing bracket 22.
[0023] Reference Figure 2-3 To save workshop space, casters 4 are installed at the bottom of the frame 1, and adjusting screws 5 are threaded at the four corners of the frame 1. Support pads 6 are rotatably connected to the bottom of the adjusting screws 5. When the auxiliary welding fixture is not in use, it can be pushed to the designated position using the casters 4, thereby freeing up workshop space.
[0024] In this embodiment of the application, the implementation principle of an auxiliary welding fixture for the production of exhaust pipes is as follows: In use, the operator first hangs one end of the flange bend on the pipe into the arc-shaped placement groove 2421 of the positioning seat 242, and clamps and fixes the flange bend onto the positioning seat 242 using quick clamps 243, so that the pipe is vertically abutting against the side of the support block 252. Then, the seat is placed on the three-jaw chuck 32 and centered and fixed using the three-jaw chuck 32. After that, the pipe is lowered down using the winch 21, so that the bottom of the pipe is inserted into the middle of the seat. The operator can know the distance the pipe has entered the seat according to the scale bar 7. Finally, the welder can perform welding, which is not only convenient to operate, but also improves the welding quality.
