Protection type multi-angle welding device for steel machining

Abstract

The invention discloses a protection type multi-angle welding device for steel machining, and belongs to the technical field of steel machining and welding. The protection type multi-angle welding device comprises a rack, a direction adjusting mechanism is fixedly connected to the bottom of the rack, clamping mechanisms are arranged on two sides of the direction adjusting mechanism correspondingly, and a laser welding mechanism is arranged on one side of an inner cavity of the rack; and one side of the bottom of the laser welding mechanism is connected with a clearing mechanism, one side of the top of the laser welding mechanism communicates with a cooling mechanism, the cooling mechanism is arranged at the top of the rack, ventilation door mechanisms are arranged at openings in the two sides of the rack correspondingly, and the direction adjusting mechanism comprises a base and a fixed seat. By arranging the direction adjusting mechanism, the limiting and supporting effects after fixing are effectively improved, the stability and angle adaptability required by laser welding are met, the welding precision is effectively improved, the weld joint completeness of weldment after welding is guaranteed, generation of thermal stress is reduced, and the precision and integrity required by protection type steel welding machining are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of iron and steel processing welding, and in particular relates to a protective multi-angle welding device for iron and steel processing. Background technique [0002] Iron and steel products refer to the general designation of metal materials with the metal element iron as the main element. Welding, traditional welding is a method of joining metals by means of heating, high temperature or high pressure. Currently, steel is processed and welded by laser welding. Laser welding is an efficient and precise method that uses a high-energy-density laser beam as a heat source. Welding method. [0003] Chinese invention patent publication number is that CN106425096A discloses a kind of laser welding device. The device includes a supporting part, an incident part, a spectroscopic part, a focusing part, a preheating part and a postheating part, the supporting part is used to support the incident part, a spectroscopi...
