During the exhaust pipe production process, the exhaust manifold, the middle section of the exhaust pipe and the tail end of the exhaust pipe need to be welded together, and the exhaust manifold, the middle section of the exhaust pipe or the tail end of the exhaust pipe are also welded from multiple annular components.

[0003] For example, the application with publication number CN219854468U discloses a pipe processing and positioning device for a motorcycle exhaust pipe, which includes a base, a mounting seat, a support rod and a swinging structure. The mounting seat is fixed on the base, and the rear end of the support rod is connected to the mounting seat through the swinging structure; the front end of the support rod is provided with a conical block and a columnar block; the side of the mounting seat is provided with a positioning boss, and the swinging structure includes a transverse connecting pipe and a rotating sleeve, the right end of the transverse connecting pipe is rotatably connected to the positioning boss, the rotating sleeve is connected to the transverse connecting pipe, and the support rod and the rotating sleeve are detachably connected.

[0004] However, the positioning device in the application is not very stable, and the exhaust pipe is more likely to deviate during welding or processing, resulting in reduced processing accuracy. A welding positioning device for a motorcycle exhaust pipe is now provided that can tighten the motorcycle exhaust pipe more firmly. Utility Model Content

[0005] The purpose of the present application is to provide a welding positioning device for a motorcycle exhaust pipe in order to solve the problem that the positioning device proposed above is not stable, and the exhaust pipe is more likely to deviate during welding or processing, resulting in reduced processing accuracy.

[0006] The technical solution adopted in the present application is as follows: a welding positioning device for a motorcycle exhaust pipe, wherein a limiting block is fixedly installed on the surface of the first mounting seat, a limiting rod is fixedly installed on the side of the first mounting seat away from the limiting block, holes are opened on the surfaces of the limiting block and the limiting rod, positioning bolts are movably inserted in the holes, a positioning nut is movably installed on the surface of the positioning bolt, a moving rod is fixedly installed on the end of the positioning bolt, and a second limiting block is fixedly connected to the end of the moving rod.

[0007] By adopting the above technical solution, the motorcycle exhaust pipe needs to be welded for processing. During the processing, if the positioning device is not clamped tightly, the motorcycle exhaust pipe will be offset, resulting in reduced welding accuracy and affecting the use effect. This device places the exhaust pipe in an appropriate position, and the user rotates the positioning bolt clockwise to drive the moving rod forward through the positioning bolt until the second limit block is pushed to the surface of the exhaust pipe to clamp the exhaust pipe. When clamping the exhaust pipe, this device clamps it more firmly, the exhaust pipe will not be offset during the welding process, and the welding accuracy is high.

[0008] In a preferred embodiment, a fixing groove is formed on the upper surface of the limiting rod, and a protective foam plate is bonded to the upper surface of the fixing groove.

[0009] By adopting the above technical solution, the exhaust pipe is placed on the surface of the fixed groove, which has a supporting effect on the exhaust pipe. At the same time, in order to prevent the exhaust pipe from being plastically deformed due to continuous friction between the exhaust pipe and the fixed groove, a protective foam plate is bonded to the surface of the fixed groove, which can effectively protect the exhaust pipe and ensure that the exhaust pipe will not be plastically deformed due to collision with the device during the positioning process.

[0010] In a preferred embodiment, a device base is fixedly mounted on the lower surface of the first mounting seat, a second mounting seat is fixedly mounted on the upper surface of the device base adjacent to the first mounting seat, and a threaded hole is opened on the upper surface of the second mounting seat, and a mounting screw is movably inserted in the hole.

[0011] By adopting the above technical solution, the second mounting seat can conveniently fix the other end of the exhaust pipe, ensuring that the exhaust pipe remains in a stable state during welding, making it convenient for users to perform processing.

[0012] In a preferred embodiment, a rotating sleeve is movably mounted on one side of the second mounting seat, a stud is movably inserted on a side of the rotating sleeve away from the second mounting seat, and a fixing nut is movably mounted on the surface of the stud.

[0013] By adopting the above technical solution, the user puts the exhaust pipe into the hole, turns the stud clockwise, the end of the stud fits to the exhaust pipe, and tightens the fixing nut to fix the stud. The exhaust pipe can adjust the corresponding angle as the rotating sleeve is adjusted to meet the needs of the user.

[0014] In a preferred embodiment, a hole is opened on the surface of the rotating sleeve, an exhaust pipe is movably inserted in the hole, and a conical block is movably installed on one side of the surface of the exhaust pipe.

[0015] By adopting the above technical solution, the user puts the exhaust pipe into the rotating sleeve to fix the exhaust pipe.

[0016] In a preferred embodiment, a positioning hole is opened on the surface of the exhaust pipe, and a stop bolt is fixedly installed on the surface of the positioning hole.

[0017] By adopting the above technical solution, the stop bolt and the integral positioning device work together to prevent the exhaust pipe from moving backwards and affecting the welding work of the user.

[0018] In a preferred embodiment, a fixed leg is fixedly mounted on the lower surface of the device base.

[0019] By adopting the above technical solution, a stabilizing effect is provided to the device body.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0021] In the present application, the motorcycle exhaust pipe needs to be welded for processing. If the positioning device is not clamped tightly during the processing, the motorcycle exhaust pipe will be offset, resulting in reduced welding accuracy and affecting the use effect. The device places the exhaust pipe in an appropriate position, and the user rotates the positioning bolt clockwise to drive the moving rod forward through the positioning bolt until the second limit block is pushed to the surface of the exhaust pipe to clamp the exhaust pipe. The device clamps the exhaust pipe more firmly, and the exhaust pipe will not be offset during the welding process, and the welding accuracy is high.

[0022] Placing the exhaust pipe on the surface of the fixing groove has a supporting effect on the exhaust pipe. At the same time, in order to prevent the exhaust pipe from being plastically deformed due to continuous friction between the exhaust pipe and the fixing groove, a protective foam plate is bonded to the surface of the fixing groove, which can effectively protect the exhaust pipe and ensure that the exhaust pipe will not be plastically deformed due to collision with the device during the positioning process.

[0029] Example:

[0030] A limiting block 15 is fixedly installed on the surface of the first mounting seat 1, and a limiting rod 16 is fixedly installed on the side of the first mounting seat 1 away from the limiting block 15. Holes are opened on the surfaces of the limiting block 15 and the limiting rod 16, and a positioning bolt 13 is movably inserted in the hole. A positioning nut 14 is movably installed on the surface of the positioning bolt 13, and a moving rod 19 is fixedly installed on the end of the positioning bolt 13, and a second limiting block 20 is fixedly connected to the end of the moving rod 19.

[0031] The motorcycle exhaust pipe needs to be welded for processing. If the positioning device is not clamped tightly during the processing, the motorcycle exhaust pipe will be offset, resulting in reduced welding accuracy and affecting the use effect. This device places the exhaust pipe 7 in an appropriate position, and the user rotates the positioning bolt 13 clockwise to drive the moving rod 19 forward through the positioning bolt 13 until the second limit block 20 is pushed to the surface of the exhaust pipe 7 to clamp the exhaust pipe 7. When clamping the exhaust pipe 7, this device clamps it more firmly, and the exhaust pipe 7 will not be offset during the welding process, and the welding accuracy is high.

[0032] A fixing groove 18 is formed on the upper surface of the limiting rod 16, and a protective foam plate 6 is bonded to the upper surface of the fixing groove 18. Placing the exhaust pipe 7 on the surface of the fixing groove 18 has a supporting effect on the exhaust pipe 7. At the same time, in order to prevent the exhaust pipe 7 from being plastically deformed by continuous friction with the fixing groove 18, a protective foam plate 6 is bonded to the surface of the fixing groove 18, which can effectively protect the exhaust pipe 7 and ensure that the exhaust pipe 7 will not be plastically deformed due to collision with the device during the positioning process.

[0033] The lower surface of the first mounting seat 1 is fixedly mounted with a device base 2, and the upper surface of the device base 2 is fixedly mounted with a second mounting seat 5 adjacent to the first mounting seat 1. The upper surface of the second mounting seat 5 is provided with a threaded hole, and the hole is movably inserted with a mounting screw 4. The second mounting seat 5 is convenient for fixing the other end of the exhaust pipe 7, ensuring that the exhaust pipe 7 remains in a stable state during welding, which is convenient for users to perform processing.

[0034] A rotating sleeve 10 is movably mounted on one side of the second mounting seat 5, a stud 12 is movably inserted on the side of the rotating sleeve 10 away from the second mounting seat 5, and a fixing nut 11 is movably mounted on the surface of the stud 12. The user puts the exhaust pipe 7 into the hole, turns the stud 12 clockwise, the end of the stud 12 fits the exhaust pipe 7, and tightens the fixing nut 11 to fix the stud 12. The exhaust pipe 7 can adjust the corresponding angle with the adjustment of the rotating sleeve 10 to meet the needs of the user.

[0035] A hole is provided on the surface of the rotating sleeve 10, in which the exhaust pipe 7 is movably inserted, and a conical block 17 is movably installed on one side of the surface of the exhaust pipe 7. The user puts the exhaust pipe 7 into the rotating sleeve 10 to fix the exhaust pipe 7.

[0036] A positioning hole 8 is provided on the surface of the exhaust pipe 7, and a stop bolt 9 is fixedly installed on the surface of the positioning hole 8. The stop bolt 9 works together with the overall positioning device to prevent the exhaust pipe 7 from moving backward and affecting the welding work of the user.

[0037] The lower surface of the device base 2 is fixedly mounted with a fixed support leg 3, which provides stability to the device body.

[0038] The implementation principle of the welding positioning device embodiment of a motorcycle exhaust pipe of the present application is as follows:

[0039] The motorcycle exhaust pipe needs to be welded for processing. If the positioning device is not clamped tightly during the processing, the motorcycle exhaust pipe will be offset, resulting in reduced welding accuracy and affecting the use effect. This device places the exhaust pipe 7 in an appropriate position, and the user rotates the positioning bolt 13 clockwise to drive the moving rod 19 forward through the positioning bolt 13 until the second limit block 20 is pushed to the surface of the exhaust pipe 7 to clamp the exhaust pipe 7. When clamping the exhaust pipe 7, this device clamps it more firmly, and the exhaust pipe 7 will not be offset during the welding process, and the welding accuracy is high.

[0040] Placing the exhaust pipe 7 on the surface of the fixing groove 18 has a supporting effect on the exhaust pipe 7. At the same time, in order to prevent the exhaust pipe 7 from being plastically deformed due to continuous friction between the fixing groove 18, a protective foam plate 6 is bonded to the surface of the fixing groove 18, which can effectively protect the exhaust pipe 7 and ensure that the exhaust pipe 7 will not be plastically deformed due to collision with the device during the positioning process.

[0041] The second mounting base 5 is convenient for fixing the other end of the exhaust pipe 7, ensuring that the exhaust pipe 7 remains stable during welding, and facilitating the user to perform processing. The user puts the exhaust pipe 7 into the hole, turns the stud 12 clockwise, and the end of the stud 12 fits the exhaust pipe 7, and tightens the fixing nut 11 to fix the stud 12. The exhaust pipe 7 can adjust the corresponding angle as the rotating sleeve 10 is adjusted to meet the needs of the user.
