Rail carrier

Abstract

The invention relates to a rail carrier. The rail carrier comprises a rail frame with a first rail and a second rail, a lifting bracket mechanism, a rail motor and a rail gear, wherein the lifting bracket mechanism is mounted on the first rail; the lifting bracket mechanism is mounted on the second rail; a rail rack is engaged with the rail gear; the rail motor is connected with the rail gear andis mounted on the lifting bracket mechanism; the rail motor drives the rail gear to rotate, so that the lifting bracket mechanism moves; the lifting bracket mechanism comprises a lifting mechanism, aworkpiece front side bracket mechanism and a workpiece rear side bracket mechanism; the workpiece rear side bracket mechanism comprises a clamping arm, a supporting block, a swing air cylinder and a travelling mechanism; the workpiece front side bracket mechanism comprises a clamping arm, a supporting block and a swing air cylinder; and positioning grooves which are formed at intervals and are suitable for different widths of workpieces are formed in the supporting surface of the supporting block. The rail carrier is suitable for carrying workpieces of different vehicle models, is convenient to position and regulate, is high in regulating efficiency, and enables welding quality to be stable.

Description

technical field [0001] The invention relates to the technical field of automobile fixtures, in particular to a technology of workpiece handling equipment based on multiple vehicle types for robot spot welding operations in automobile fixtures. Background technique [0002] The body of a car is generally composed of various body sub-assemblies welded. In the existing technology, many welding production lines use robots for body welding. The car body generally includes a top cover assembly, a side wall assembly and a floor assembly, and the side wall assembly includes a door sill assembly. Before each assembly is welded, it is necessary to lift the assembly mounted on the material rack to the welding production line and put it on the body. After manual adjustment and positioning, the welding industrial robot performs welding. During this process, different The convenience of positioning and adjustment of each assembly of the vehicle model, the improvement of adjustment effici...

Problems solved by technology

At present, most domestic technologies are limited to special equipment for a single model to realize this function. This equipment is time-consuming for model switching and is not suitable for flexible production of multiple models. It cannot meet the needs of automobile factories. Some other technologies use dotting robots to take into account the handling method. There is a risk of robots waiting
