Automatic Loading Device in Body Welding

Abstract

The invention relates to an automatic part feeding device used in welding of a vehicle body, and belongs to the technical field of automobiles. In the technical scheme, the automatic part feeding device comprises a base, a rollover stand, a rollover cylinder, a propelling cylinder, a workpiece holder and a holder support, wherein the rollover stand is rotatably connected with the base through a horizontal rollover shaft; the rollover cylinder is installed on the base; a piston top rod of the rollover cylinder is hinged with the rollover stand; the upper end of the holder support is fixed with the workpiece holder and the lower end of the holder support is connected with the rollover stand through a propelling slide rail; the propelling cylinder is fixed on the rollover stand; and a piston top rod of the propelling cylinder is connected with the holder support. By the automatic part feeding device, all actions can be automatically completed according to programs, part feeding automation in a vehicle body welding process is realized, the working efficiency is greatly improved, negative influence of human factors on part feeding is eliminated, the welding quality of the vehicle body is ensured, and accident potential caused by manual part feeding is also avoided.

Description

technical field [0001] The invention relates to a device for automatically clamping a sheet metal part and placing the workpiece at a designated position on the vehicle body during the welding process of a vehicle body, belonging to the technical field of automobiles. Background technique [0002] At present, when welding body sheet metal parts, manual loading is generally used. During the loading process, employees remove the workpiece from the material box, and then fix the workpiece to the designated position on the body with clamps. The disadvantage of this loading method is that the labor intensity of the employees is high, the conveying efficiency is low, and it cannot meet the requirements of the automatic production line, and because most of the automatic production lines use automatic equipment, the personal safety of the manual loading employees is not guaranteed, and there are major safety hazards. In addition, the welding production line is a flexible production ...

The disadvantage of this loading method is that the labor intensity of the employees is high, the conveying efficiency is low, and it cannot meet the requirements of the automatic production line, and because most of the automatic production lines use automatic equipment, the personal safety of the manual loading employees is not guaranteed, and there are major safety hazards

In addition, the welding production line is a flexible production line. When a variety of vehicle models cross-operate, it is necessary to accurately identify the type of workpiece. Affected by the quality of the employees, it is difficult to ensure the accuracy of workpiece identification by manual loading, which is likely to cause welding errors.
