Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic clamps, in particular to a pneumatic clamp for an industrial robot. Background Art

[0002] Pneumatic clamps are clamps that use air pressure as a power source to clamp and position workpieces. Pneumatic clamps play an increasingly important role in the manufacturing industry, significantly improving production efficiency and reducing production costs.

[0003] Common pneumatic clamps for industrial robots generally use a cylinder to drive the piston rod to move, which in turn drives the clamping plate to move, and clamps industrial objects through the clamping elements on the surface of the clamping plate. However, due to the large variety of items that need to be clamped in industry and the fact that the clamping elements are in a fixed state, when clamping smaller industrial parts, the clamping elements are easily misaligned with the industrial parts, making it difficult for the clamp to clamp smaller parts. At the same time, due to the slightly lower clamping accuracy of pneumatic clamps and the difficulty in fine-tuning, pneumatic clamps are not suitable for clamping objects with higher precision.
