Welding fixture switching device

Abstract

The invention discloses a welding fixture switching device, and belongs to the field of welding for automobile production lines. The welding fixture switching device comprises a welding fixture mounting base. Two power distribution box connecting rods are fixedly connected to the upper end of the welding fixture mounting base. A power distribution box is arranged on the left side of the welding fixture mounting base and is fixedly connected with the power distribution box connecting rods. An electromagnetic valve mounting frame is arranged on the right side of the power distribution box and isfixedly connected with the upper end of the welding fixture mounting base. An electromagnetic valve is fixedly connected into the electromagnetic valve mounting frame. An aviation plug is arranged onthe right side of the electromagnetic valve mounting frame. Through the electromagnetic valve, the electromagnetic valve mounting frame and the aviation plug additionally arranged on the welding fixture mounting base, a limiting sensor and a jacking cylinder, jacking and positioning can be achieved through the cylinder, so that it is ensured that the sensor and the aviation plug are located at the position of a limiting block every time a welding fixture is switched to a specified position so as to recognize different switching devices, and misplacing or placing omission is effectively avoided.

Description

technical field [0001] The invention relates to the field of welding of automobile production lines, and more specifically relates to a welding fixture switching device. Background technique [0002] Welding, also known as welding and welding, is a manufacturing process and technology for joining metals or other thermoplastic materials such as plastics by means of heating, high temperature or high pressure. There are three main methods of welding: fusion welding, heating the workpiece to be joined The local melting forms a molten pool, and the molten pool will be joined after cooling and solidification. If necessary, fillers can be added to assist. It is suitable for welding of various metals and alloys without pressure; pressure welding must be applied to the weldment during the welding process. Pressure, which belongs to the processing of various metal materials and some metal materials; brazing, using metal materials with a lower melting point than the base metal as the s...

Problems solved by technology

[0003] Cars are constantly updating styles, making the shapes of parts such as the body diverse. Due to the limited space in the workstation, a large number of fixtures cannot be placed, so it is necessary to make a switching device to solve this problem. Large, low precision, relatively poor production quality, and unstable quality. At the same time, because the existing welding fixtures need to be switched manually, the switching process is very complicated, which takes up a lot of welding time and reduces welding efficiency.
