New automatic welding equipment for exhaust manifold and working method of new automatic welding equipment

Abstract

The invention provides new automatic welding equipment for an exhaust manifold and a working method of the new automatic welding equipment. The new automatic welding equipment comprises equipment racks, single-section welding worktables, a multifunctional manipulator, a flange slideway, a combined welding worktable and a polishing device; the single-section welding worktables can move butt weld leftwards and rightwards and overturn the butt weld, a weldment can be rotated through arranged clamping claws during welding, all sections of manifolds can be combined and butted together through the combined welding worktable, and after an exhaust main pipe is welded, polishing can be automatically conducted; and the multifunctional manipulator is provided with an automatic clamping structure, andworking heads can be automatically replaced and clamped through the automatic clamping mechanism. According to the new automatic welding equipment for the exhaust manifold and the working method of the new automatic welding equipment, segmented welding is conducted first, then overall welding is conducted, polishing is conducted after welding, the working heads of the equipment can be automatically replaced, thus the functions of welding, carrying, detecting and stress removing are achieved, and the new automatic welding equipment is quite suitable for welding of the exhaust manifold.

Description

technical field [0001] The invention belongs to the technical field of automobile parts processing, and relates to a new type of automatic welding equipment for exhaust manifolds and a working method thereof. Background technique [0002] Exhaust manifold is an important component 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 welding seam at one time, and the welding 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, which will seriously affect the production efficiency and increase labor costs; and the inner surface of the exhaust manifold after welding is completed. The existence of welding slag, burrs and other debris in the weld will increase the exhaust resistance, and the exhaust wi...

[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, the welding stress generated during welding cannot be removed, which affects the welding quality
