Abstract

The utility model provides a flexible base of a robot welding tool clamp, and relates to the technical field of flexible bases. The four corners of the bottom of the flexible workbench are fixedly provided with vertically-downward supporting columns correspondingly. Symmetrical fixing blocks are inserted into the front end and the rear end of the flexible workbench respectively; the front clamping plate and the rear clamping plate oppositely move to stably clamp the front end and the rear end of a welding piece through the inner side wall, then the lower pressing plate is used for downwards extruding the welding piece, meanwhile, the limiting plates at the left end and the right end oppositely move, and the limiting plates are used for clamping and fixing the left end and the right end of the welding piece. In this way, a welding part placed on the flexible base can be fixed and limited by weight, and the problems that the four corners and the upper end of the welding part need to be stably clamped due to the fact that the welding part needs to be placed on the flexible base for stable welding, and otherwise the welding part deviates when a robot frequently touches the welding part and cannot be accurately and stably welded are solved.

Description

Technical Field

[0001] The utility model relates to the technical field of flexible bases, in particular to a flexible base for a robot welding fixture. Background Art

[0002] With the continuous improvement of the level of industrial automation, traditional tooling and fixtures are usually made of steel plates, aluminum alloys and other materials, with strong fixation, suitable for some routine welding tasks. However, in modern manufacturing, the types and changes of products are increasing. Traditional fixed tooling and fixtures are often difficult to adapt to the diversity and flexibility requirements of product welding. It is particularly urgent to develop a new type of flexible base for robot welding tooling and fixtures. The traditional tooling and fixtures are insufficient in flexibility and adaptability, so a flexible base is needed. The flexible base is made of flexible materials and has certain deformation ability and adaptability. It can be freely adjusted according to the shape and size of different products, thereby achieving more flexible and efficient welding operations.

[0003] During the robot's welding process on the flexible base, since the weldment needs to be placed on the flexible base for stable welding, the weldment needs to be firmly clamped at the four corners and the upper end. Otherwise, the robot will deviate when frequently touching the weldment and will not be able to perform accurate and stable welding. Utility Model Content

[0004] The disclosed embodiment relates to a flexible base for a robot welding fixture. During the welding process of a welded part placed on the flexible base, the front and rear clamping plates move towards each other and use the inner side walls to firmly clamp the front and rear ends of the welded part. Then the lower pressure plate is used to press the welded part downward. At the same time, the limit plates at the left and right ends move towards each other and use the limit plates to clamp and fix the left and right ends of the welded part. In this way, the welded part placed on the flexible base will be subject to heavy fixed restrictions. When the welded part is frequently contacted by the robot during welding, the welded part will not shift, thereby achieving accurate and stable welding. The flexible base can achieve rapid adjustment and alignment to improve welding efficiency. The flexible base also has certain deformation ability and adjustability to meet the welding requirements of different products.
