A ring automatic welding device with a protective cover for easy unloading

Abstract

The invention discloses an automatic circle welding device being provided with a protective cover and capable of facilitating discharging. The device comprises a fixing frame and a welding machine, wherein a positioning air cylinder is arranged in the middle of the upper end of the fixing frame; a material receiving plane is arranged below the positioning air cylinder; a rotating shaft is arranged below the material receiving plane, and upper and lower ends of the rotating shaft are fixed on the fixing frame through bearings; a transmission wheel is arranged in the middle of the rotating shaft and connected onto an output shaft of a driving motor through a belt; the driving motor is fixedly mounted at the lower end of the fixing frame; the upper end of the rotating shaft extends to the upper end surface of the material receiving plane; a hole matched with the rotating shaft is formed in the material receiving plane; a switch contacted with a welding head is arranged at the front end of the air cylinder; protective bodies are arranged on two sides of the fixing frame. By the aid of the device, the problems that circular contact surfaces are not easy to weld and a lot of welding points exist are solved, a to-be-welded component is positioned and rotated through the positioning air cylinder and the rotating shaft, the component is rotationally welded, and seamless welding is realized; the material receiving plane can be rotationally inclined, so that residues can be cleaned timely, automatically and conveniently.

Description

technical field [0001] The invention relates to the technical field of circular ring welding, in particular to a circular ring automatic welding device with a protective cover for easy unloading. Background technique [0002] The side fixing plate part of the existing hydraulic jack is composed of a plane and a plurality of bolt positioning holes. During production and processing, it is necessary to weld several raised small cylinders on one plane, and the surface to be welded is ring-shaped. Because the parts to be welded are relatively small, it is not easy to fix them for welding; The plane is fixed, and then the small cylinder is positioned manually with the aid of auxiliary tools, and then welded. In this way, there are more solder joints on the welding contact surface, which is not conducive to the subsequent painting process. The solder joints need to be polished, which is prone to false welding, and the operation is cumbersome , low production efficiency, poor produ...
