Abstract

The invention discloses a pneumatic quick-changing clamp which comprises a driving part and a reloading part, wherein the driving part and the reloading part form pneumatic clamping connection througha plurality of balls distributed on the circumference of the driving part and matching holes in the reloading part; and an annular arc shaped groove for receiving the balls is formed in the walls ofthe matching holes. With adoption of the pneumatic quick-changing clamp, the annular arc shaped groove for receiving the balls is formed in the walls of the matching holes, when the pressure force issufficient, frictional resistance generated by positive pressure exists between the balls and the reloading part, and a radial overlapped part bears the axial force formed by the gravity of a workpiece and the reloading part; and the pneumatic quick-changing clamp can remarkably increase the load of the quick-changing clamp, can meet the using requirements of large and medium-sized components andis simple in structure and convenient to machine.

Description

technical field [0001] The invention relates to a clamp, in particular to a pneumatic quick-change clamp. Background technique [0002] When the workpiece needs to change the processing orientation and operating machine position, the manual operation and changing the station are inefficient and difficult to operate. In order to solve this problem, an automatic changeover method in which robots are used to replace manual labor is introduced, which realizes quick changeover through the pneumatic quick-change structure between the active part fixedly connected on the robot and the changeover part fixedly connected to the workpiece, thus The workpiece is driven by the robot to clamp the product on the processing equipment, or to achieve grinding, welding and other processing purposes with the robot's set motion trajectory; and use the changing part to connect with different workpieces to achieve the purpose of workpiece replacement. The existing pneumatic quick change structure...
