Description

Technical Field

[0001] The utility model relates to a multifunctional spacer sleeve bearing clamp and belongs to the technical field of intelligent robots. Background Art

[0002] Industrial robot arms are mechanical and electronic devices that anthropomorphize the functions of human arms, wrists, and hands. They can move any object or tool according to the time-varying requirements of spatial posture (position and posture) to complete the work requirements of a certain industrial production. For example, they can clamp welding tongs or welding guns to spot weld or arc weld the body of a car or motorcycle; carry die-cast or stamped parts or components; perform laser cutting; spray painting; assemble mechanical parts, etc.

[0003] In terms of handling parts, the existing robotic arm grippers are mostly single-function and can only achieve single clamping or adsorption, and cannot well meet the needs of synchronous or alternating use. When switching to different usage requirements, the switching is achieved by replacing the clamping mechanism. Some fixed robotic arms cannot replace the clamping mechanism, so it is necessary to set up robotic arms with other clamping methods, which is costly and not conducive to effective cost control.

The close setting makes positioning more convenient.

[0015] Preferably, the gripper assembly further comprises a straight-cylindrical filter fixedly mounted on the gripper mounting frame, and the straight-cylindrical filter is disposed on a pipeline between the vacuum generator and the suction cup gripper.
