Safe automatic exhaust manifold welding device and working method thereof

Abstract

The invention provides a safe automatic exhaust manifold welding device and a working method thereof. The safe automatic exhaust manifold welding device comprises a device rack, a single-section welding working table, a welding, carrying and detecting manipulator, a flange slideway, a combined welding working table, a polishing device and a safe protection device, wherein the single-section welding working table can move left and right and turn over for butt weld; an arranged clamping jaw can rotate a weld piece during welding; a clamping and welding device of the welding, carrying and detecting manipulator has welding, carrying and detecting functions; the combined welding working table can be used for combining and butt-jointing various sections of manifolds, and a polishing program canbe automatically started after an exhaust manifold is welded; and the safe protection device comprises a safe protection door and a filter coating. According to the safe automatic exhaust manifold welding device and the working method thereof provided by the invention, through arranging the safe protection device, the occurrence of the phenomenon that personnel enters the working area when the device works so as to cause mechanical injury is effectively prevented, and welding spatter is isolated; and the filter coating is arranged at the same time, so that harmful light rays produced during welding can be filtered, and the personnel can conveniently observe and spot-inspect the device.

Description

Technical field [0001] The invention belongs to the technical field of automobile parts processing, and relates to a safe automatic welding equipment for an exhaust manifold and a working method thereof. Background technique [0002] Exhaust manifold is an important part of automobile manufacturing. At present, manual welding is mainly used in the welding process of exhaust manifold. However, the existing manual welding cannot complete the welding of the weld at one time, and the weld is uniform during welding. Poor performance, resulting in unstable welding quality; at the same time, it is necessary to repeatedly fix the exhaust manifold in the fixture to adjust the butt weld seam during welding, which seriously affects production efficiency and increases labor costs; and the inner surface of the exhaust manifold after welding is completed The presence of welding slag, burrs and other debris in the weld will increase the exhaust resistance, and the exhaust will be disordered, wh...

[0002] Exhaust manifold is an important part in automobile manufacturing. At present, manual welding is mainly used in the welding process of exhaust manifold. However, the existing manual welding cannot complete the welding of the weld seam at one time, and the weld seam is uniform during welding. poor performance, resulting in unstable welding quality; at the same time, it is necessary to repeatedly fix the exhaust manifold in the fixture to adjust the butt weld during welding, which seriously affects production efficiency and increases labor costs; and the inner surface of the exhaust manifold after welding is completed There are welding slag, burrs and other debris in the weld, which will increase the exhaust resistance, and the exhaust will be disordered, which will affect the normal operation of the engine; the air tightness of the weld cannot be detected in time after welding. If the air tightness is poor, it needs to be reworked , time-consuming and labor-intensive; at the same time, when the existing welding equipment is working, personnel can freely enter the working area of ​​the equipment, which may easily cause production safety accidents, and it is impossible to conveniently observe the welding position during welding
