Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, in particular to a welding tool for processing automobile exhaust pipes. Background Art

[0002] The exhaust pipe is a part of the engine's exhaust system. The exhaust system mainly includes the exhaust manifold, exhaust pipe and muffler. Generally, a 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.

[0003] Welding tooling is required for the processing of exhaust pipes. However, in the existing exhaust pipe welding, most of the two parts to be welded are clamped and connected by welding tooling, and then welded manually. Manual welding has high work intensity and large labor volume. At the same time, the exhaust pipe parts are not easy to flip over after clamping, so multiple flips are required to complete the welding work during welding. Therefore, the welding work efficiency is low. For this reason, we propose a welding tool for automobile exhaust pipe processing. Utility Model Content

[0004] The utility model provides a welding tool for processing an automobile exhaust pipe to solve the problems raised in the background technology.

[0005] In order to solve the above problems, the utility model provides a welding tool for automobile exhaust pipe processing, including a workbench, a reduction motor, and a welding mechanism. A mounting groove is provided in the middle of the workbench, and a symmetrical first annular frame and a second annular frame are fixedly installed in the mounting groove. A first clamping ring and a second clamping ring are rotatably provided in the first annular frame and the second annular frame respectively. An annular gear bar is provided on the outside of the first clamping ring and the second clamping ring respectively. The annular gear bar on the outside of the first clamping ring is meshed with a first driving gear, and the annular gear bar on the outside of the second clamping ring is meshed with a second driving gear. The first driving gear and the second driving gear are fixedly installed on a driving shaft, and the driving shaft is rotatably installed on one side above the workbench. The reduction motor is fixedly installed on the workbench, and the power output shaft is connected to the driving shaft. The welding mechanism is arranged at the mounting groove in the workbench and away from the side of the driving shaft. The welding mechanism is composed of a welding gun, a movable plate, a lifting plate, a second electric telescopic rod, and a third electric telescopic rod.

[0006] Preferably, two first electric telescopic rods that move relative to each other are symmetrically arranged in the first clamping ring and the second clamping ring, and clamping plates are threadedly mounted on the ends of the first electric telescopic rods.

[0007] Preferably, the welding gun is located at the center between the first clamping ring and the second clamping ring.

[0008] Preferably: the welding gun in the welding mechanism is fixedly mounted on a movable plate, the movable plate is slidably connected to the lifting plate, the bottom of the lifting plate is connected to the telescopic end of the second electric telescopic rod, the second electric telescopic rod is installed in the workbench, the third electric telescopic rod is fixedly mounted on the lifting plate, and the telescopic end is connected to the bottom surface of the movable plate.

[0009] The beneficial effects of adopting the above technical solution are:

[0010] 1. The two parts to be welded can be clamped by the rotation setting of the first clamping ring and the second clamping ring. The driving shaft is driven to rotate by the reduction motor, so that the first driving gear and the second driving gear are rotated, thereby driving the first clamping ring and the second clamping ring to rotate in the first annular frame and the second annular frame respectively through the meshing annular rack, so that the two clamped parts are rotated, and then the welding gun in the welding mechanism is cooperated to perform automatic welding, thereby reducing labor and improving work efficiency.

[0011] 2. The clamping plate is driven to move by the first electric telescopic rod, and exhaust pipe components of different sizes that need to be welded can be clamped. Through the threaded installation of the clamping plate and the end of the first electric telescopic rod, it is convenient to replace clamping plates of different shapes according to the shape of the exhaust pipe, and then clamp exhaust pipes of different shapes, thereby improving the applicability of the equipment.

[0012] 3. The lifting plate is lifted and lowered by the second electric telescopic rod, and the movable plate is moved in the lifting plate by the third electric telescopic rod, so that the welding gun is moved to adjust the position, so as to facilitate welding of parts of different sizes and shapes clamped in the first clamping ring and the second clamping ring, thereby improving welding efficiency.
