Automatic laser welding device for fixing legs of motor shell

Abstract

The invention provides an automatic laser welding device for fixing legs of a motor shell. The automatic laser welding device comprises a rack, a base plate, positioning mould components and a cam indexer component, a hydraulic cylinder heavy pressing component, a combination welding component, a workpiece ejection component, an automatic discharging component and a blanking slideway which are arranged on the base plate; each positioning mould component comprises a positioning mould and buffering connectors which are uniformly arranged around the positioning mould; the six positioning mould components are uniformly arranged on the worktable; and the hydraulic cylinder heavy pressing component, the combination welding component, the workpiece ejection component, the automatic discharging component and the blanking slideway are sequentially arranged on the periphery of the worktable. According to the automatic laser welding device, a welding structure is optimally designed according to the stressed states of the fixing legs; laser is utilized for seam welding along the edge outline of the fit area of the arc surface of each fixing leg and the outer wall of the cylindrical shell; bearing capacity of the fixing legs is greatly improved; welding quality is high; the automation degree is high; technological repeatability is good; and welding efficiency is higher.

Description

technical field [0001] The invention belongs to the field of laser processing, and in particular relates to an automatic laser welding device for fixing feet of a motor housing. Background technique [0002] According to the needs of the occasion, the outer wall of some motor housings needs to be provided with motor housing fixing feet for mounting the motor on a certain device. Such as figure 1 As shown, the motor casing includes a cylindrical casing 2022, and three fixing feet 2021 are uniformly arranged on the outer wall of the cylindrical casing 2022, and the fixing feet 2021 include an arc-shaped curved surface and a connecting plane, so The arc-shaped curved surface is completely connected to the outer wall of the cylindrical housing 2022, and the connecting plane is used for connecting with external devices. Since the connecting surface of the fixing foot 2021 and the cylindrical housing 2022 is a curved surface, its processing is relatively complicated. At present...

Problems solved by technology

However, this kind of resistance pressure welding cannot realize the edge contour seam welding of the arc-shaped surface of the fixed foot and the outer wall of the cylindrical shell, which limits the maximum bearing capacity of the fixed foot, and the bending of the fixed foot during service Torque force makes the resistance pressure welding joint between the fixed foot and the outer wall of the cylindrical shell prone to cracks and fractures; and the traditional resistance pressure welding of the fixed foot is generally manual welding or semi-automatic welding, the production efficiency is low, and manual operation cannot guarantee the motor casing. The quality of the body and the poor consistency of the finished product lead to a high rate of defective products and high production costs
