Cantilever crane for station for welding operation

Abstract

The invention discloses a cantilever crane for a station for a welding operation, and the cantilever crane is fixedly arranged on a stand column (1); the bottom of the stand column (1) is connected with a base, the base is fixed on the ground by a bolt (2), the upper part of the stand column (1) is provided with a movable buckle (4) by a movable sleeve, the movable buckle is connected with one end of a cantilever beam (3), and the cantilever beam (3) can rotate around the stand column (1) by the movable sleeve. By utilizing the technical scheme, the cantilever crane for the station for the welding operation has a simple structure, is convenient in operation and is small in occupied area, enough spaces are reserved below the cantilever crane and used for placing clamps and station devices, the using condition of a bearing is checked annually, and besides lubricating, the bearing only needs daily and necessary point inspection, and the maintenance load is low.

Description

technical field [0001] The invention belongs to automobile welding auxiliary equipment, more specifically, the invention relates to a double rocker arm cantilever crane for a welding work station. Background technique [0002] In the automobile manufacturing process, four major processes are involved: stamping, welding, painting, and final assembly. The welding process of the body-in-white forms the skeleton of the body-in-white. During the welding process of the body-in-white, it involves the welding of the sub-assembly assemblies such as the front floor, rear floor, engine compartment, left side wall, and right side wall. Most of these are suspended Spot welding machine welding, and their working stations mainly adopt the method of hanging welding machines and welding tongs under the door-shaped steel structure, but in order to meet the requirements of production and technology, there are also some sub-assemblies for production, only one In the past, the single work stati...

Problems solved by technology

[0002] In the automobile manufacturing process, four major processes are involved: stamping, welding, painting, and final assembly. As one of the important and indispensable processes in the four major processes of automobile manufacturing, welding can make the stamping parts processed by stamping process according to certain requirements. The welding process of the body-in-white forms the skeleton of the body-in-white. During the welding process of the body-in-white, it involves the welding of the subassembly assemblies such as the front floor, rear floor, engine compartment, left side wall, and right side wall. Most of these are suspended Spot welding machine welding, and their working stations mainly adopt the method of hanging welding machines and welding tongs under the door-shaped steel structure, but in order to meet the requirements of production and technology, there are also some sub-assemblies for production, only one In the past, the single station usually adopts the L-shaped steel structure. This structure has the disadvantages of large floor area and inconvenient operation, which has caused certain impact on the existing production process and safety.
