Double-section type exhaust pipe welding device capable of carrying out leakage detection on exhaust pipe

Abstract

The invention discloses a double-section type exhaust pipe welding device capable of carrying out leakage detection on an exhaust pipe. The double-section type exhaust pipe welding device comprises abottom plate, a clamping mechanism, a sliding rail, a welding mechanism and a movable sleeve, wherein a movable rail is installed on one side of the top of the bottom plate, a machine cabinet is fixedto one side of the top of the bottom plate, a servo motor is installed on the side, away from the machine cabinet, in the movable rail, and a lead screw is installed at the output end of the servo motor. According to the double-section type exhaust pipe welding device capable of conducting leakage detection on the exhaust pipe, through arrangement of an air pump and an ultrasonic air leakage detector, the air pump can blow air to the welded exhaust pipe, the ultrasonic air leakage detector can surround a welding part to detect air pressure leakage and welding sealing performance of the welding part, and meanwhile intelligently position an air leakage position, the welding mechanism can conduct and secondary repair welding work on the air leakage position in time, so that time and labor are saved, the integration degree is high, and the welding quality is higher.

Problems solved by technology

[0002] Automobile exhaust bellows, also known as automobile exhaust pipe hose, is installed in the exhaust pipe between the engine exhaust branch pipe and the muffler, so that the entire exhaust system is flexibly connected, thereby reducing vibration and noise, and is convenient. The role of installing and prolonging the life of the exhaust muffler system. Existing automobile exhaust pipes are mostly welded after processing plates and pipes. Because of the difficulty in the integral molding process, although the sealing is good, it is not accepted due to high cost. use

[0003] At present, the welding of automobile exhaust pipes is mostly manual welding. Since the exhaust pipe itself is a bent tubular structure, it is difficult to fix it during welding, and it is difficult to accurately connect the parts to be welded. In addition, after welding It is not possible to directly test the tightness of the pipeline, so the welding quality cannot be guaranteed
