Description

Technical Field

[0001] The utility model relates to the technical field of automobile exhaust pipe processing, and particularly relates to a fixing device for exhaust pipe welding. Background Technique

[0002] The automobile exhaust pipe can make the whole exhaust system be flexibly connected, so as to play the roles of shock absorption and noise reduction, convenient installation and extension of the service life of the exhaust silencing system. During the welding and forming process of the exhaust pipe, due to the high requirement for sealing performance, argon arc welding with high precision is generally used for welding. The welding principle of argon arc welding is to cover point by point and connect them into a line, so as to ensure the sealing performance of the exhaust pipe. The exhaust pipe is of a tubular structure, and the welding position is circular welding. Therefore, during the welding process, in order to ensure the welding efficiency, the fixing device of the exhaust pipe is particularly important.

[0003] The fixing device of the exhaust pipe is used in cooperation with a welding machine or manually. It needs to meet the convenience of circular welding and at the same time be convenient for position adjustment. The fixing device in the prior art, such as the application number 202222550646.X, discloses a fixing device for automobile exhaust pipe welding, which can clamp and fix pipe fittings of different lengths. However, its fixing structure blocks the welding position of the pipe fittings during the fixing process and cannot rotate during the welding process, so it is not convenient for circular welding. At the same time, it cannot make adaptive adjustment to the welding position through the position or angle adjustment of the fixing device, resulting in low welding efficiency when the fixing device cooperates with a welding machine or different workers. Content of the Utility Model

[0004] The purpose of the utility model is to provide a fixing device for exhaust pipe welding, which solves the problems that when the fixing device of the exhaust pipe in the prior art fixes and welds the exhaust pipe, it cannot adjust the height position of the welding position, and at the same time is not convenient for circular welding, resulting in low welding efficiency.

[0005] To achieve the above purpose, the utility model provides the following technical scheme:

[0006] A fixing device for exhaust pipe welding, comprising a mounting frame and a rotating platform movably mounted on the mounting frame. A clamping mechanism is rotatably mounted on the rotating platform to clamp and fix one end of the exhaust pipe, and the clamping mechanism is driven to rotate by a driving mechanism arranged on the rotating platform.

[0007] With the above structural design, the position of the clamping mechanism can be adjusted in the height direction through the arranged rotating platform to adapt to different welding positions. At the same time, a rotatable clamping mechanism is arranged on the rotating platform, so that automatic rotation can be realized during welding, which is convenient for circular welding of the exhaust pipe, and therefore the welding efficiency of the exhaust pipe is improved.

[0008] Preferably, both sides of the rotating platform are rotatably installed on the mounting frame through rotating shafts, and the inside of the rotating platform is a hollow structure. A rotating shaft is movably installed on the rotating platform, and the other end of the rotating shaft is fixedly connected to the clamping mechanism.

[0009] With the above structure, by setting the rotation directions of the rotating platform and the clamping mechanism differently, the overall height can be adjusted by the rotating platform together with the clamping mechanism. At the same time, the clamping mechanism drives the exhaust pipe to rotate alone for welding during the processing.

[0010] Preferably, the driving mechanism includes a driving motor. The output end of the driving motor is arranged inside the rotating platform and is drivingly connected to the rotating shaft to drive the rotating shaft to rotate.

[0011] Preferably, one end of the clamping mechanism is fixedly connected to the rotating shaft, and an installation hole is formed in the middle of the other end. A plurality of movable claws are arranged at the installation hole to fix the exhaust pipe.

[0012] With the above structural design, one end of the exhaust pipe is fixed unidirectionally by the claws to maintain the clamping depth, so that there will be no shaking. Moreover, the fixation at one end can improve the space for welding operation and is also convenient for position adjustment in the height direction.

[0013] Preferably, vertical frames are arranged on both sides of the mounting frame. The rotating shafts on both sides of the rotating platform are movably installed on the vertical frames, and an adjusting mechanism for adjusting the angle of the rotating platform is arranged at the installation position on one side.

[0014] Preferably, the adjusting mechanism includes an adjusting gear fixedly installed on the rotating shaft. An adjusting screw rod meshing with the adjusting gear is arranged below the adjusting gear, and a rotating handle is arranged at one end of the adjusting screw rod.

[0015] With the above structural design, it is convenient to adjust the height position according to requirements. Moreover, the adjusting mechanism uses the rotation of the screw rod for adjustment, with higher adjustment accuracy and stronger stability.

[0016] Preferably, a protective housing is arranged outside the adjusting gear and the adjusting screw rod, and the lower end of the protective housing is fixedly installed on the vertical frame.

[0017] With the above structural design, the cooperation between the adjusting screw rod and the adjusting gear can be protected to prevent foreign objects from entering and affecting their work.

[0018] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0019] 1. The utility model adjusts the position of the clamping mechanism and its exhaust pipe in the height direction by setting a rotating platform on the mounting frame to adapt to different welding positions. At the same time, a rotatable clamping mechanism is arranged on the rotating platform, and the clamping mechanism is driven to rotate independently by a driving mechanism arranged on the rotating platform, which is convenient for the circular welding of the exhaust pipe. Therefore, the welding efficiency of the exhaust pipe is improved;

[0020] 2. The height direction position of the rotating platform of the utility model is adjusted by an adjusting mechanism arranged on one side, and the adjusting mechanism adopts the cooperation mode of an adjusting screw and an adjusting gear, with simple structure, convenient adjustment and strong stability;

[0021] 3. The whole of the utility model is convenient to install and can adjust the welding position. Therefore, it can be applied to welding machines and manual welding, improving the versatility of the device. Description of the Drawings
