Outer edge welding device for hydraulic cylinder manufacturing

Abstract

The invention provides an outer edge welding device for hydraulic cylinder manufacturing, and relates to the technical field of hydraulic cylinder welding. Two sliding adjusting parts are mounted on the mounting supporting part; the structures on the two sliding adjusting parts are the same; a movable seam clamping device is connected to the mounting supporting part in a sliding manner; the movable seam clamping device is fixedly connected with an elastic positioning device; the two sliding adjusting parts are rotationally connected with rotating mounting parts correspondingly. Arc-shaped swing welding can be achieved, welding is firmer, the overall linkage performance is higher, and auxiliary smoke removal and cleaning work can be achieved; the problems that an existing outer edge welding device for hydraulic cylinder manufacturing is low in overall installation precision, meanwhile, welding is not stable enough, simultaneous rotating welding cannot be achieved, meanwhile, flexible welding line adjustment cannot be achieved, the welding quality is affected, meanwhile, arc swing welding cannot be achieved, and swing adjustment is not convenient and fast enough are solved.

Description

technical field [0001] The invention relates to the technical field of hydraulic cylinder welding, in particular to an outer edge welding device used for the manufacture of hydraulic cylinders. Background technique [0002] Hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion or swinging motion; it has a simple structure and reliable operation. When using it to achieve reciprocating motion, the reduction device can be omitted, and there is no transmission gap, and the movement is stable, so it is widely used in various mechanical hydraulic systems. In the actual assembly and maintenance process of the hydraulic cylinder, it is often necessary to Its welding is a linear drive component with the hydraulic cylinder. At this time, an outer edge welding device made of a high-precision hydraulic cylinder is particularly important. [0003] However, as far as the outer edge welding device manufact...
