Description

Technical Field

[0001] The utility model relates to the technical field of industrial robots, in particular to a composite clamp for industrial robots. Background Art

[0002] Industrial robots are multi-joint manipulators or multi-degree-of-freedom machine devices widely used in the industrial field. They have a certain degree of automation and can rely on their own power and control capabilities to achieve various industrial processing and manufacturing functions. During use, they need to use fixtures to clamp and fix the workpiece, so as to operate and move the workpiece.

[0003] At present, existing industrial robots involve clamping and fixing workpieces of different specifications during use. Without replacement, their fixtures can only clamp different workpieces from a fixed position. Due to the differences in the center of gravity and shape of the workpieces, the clamping is prone to unstable and loose conditions. In addition, there is a lack of anti-falling structure, which poses certain safety hazards.

[0004] Therefore, in view of the problem that the above-mentioned existing industrial robot clamps are prone to unstable and loose clamping due to differences in the center of gravity and shape of the workpiece, and lack anti-falling structure, which poses certain safety hazards, an industrial robot composite clamp can be designed. By setting up a flexibly adjustable clamping structure, it is convenient to clamp and fix workpieces of different specifications. By setting up a supporting structure, the stability of the workpiece clamping is improved, and the workpiece is effectively prevented from loosening and falling off. Utility Model Content
