[0022] Specifically, the clamp cylinder 1 is a finger cylinder having two opposite clamping ends. The model of the clamp cylinder 1 is preferably: AIRTAC finger cylinder HFP32.

[0023] The pressurizing column 4 is a cylindrical structure, and the axis of the pressurizing column 4 connected to the upper end surface of the grinding fixture 5 is perpendicular to the grinding fixture 5. A pair of clamping plates are respectively vertically connected to the two clamping ends of the telescopic cylinder, and the pair of clamping plates are located on both sides of the pressurizing column 4 and parallel to the pressurizing column 4.

[0024] The clamp cylinder 1 is arranged on a three-axis displacement platform, which controls the displacement of the clamp cylinder 1 . The two clamping ends of the clamp cylinder 1 simultaneously open and close relative to each other to drive a pair of clamping plates to snap together and grasp the pressurizing column 4 or to separate and loosen the pressurizing column 4 .

[0025] Furthermore, a nesting component is provided between the pair of clamping plates and the pressurizing column 4 , and the pressurizing column 4 can be grasped or loosened by the nesting cooperation of the nesting component.
