Abstract

The invention discloses a clamping device, in particular to a pneumatic type raised head clamping device. The pneumatic type raised head clamping device comprises a clamping body, a toggle rod mechanism, a cylinder body capable of moving on the clamping body laterally and transversely, a support block capable of supporting a workpiece and a clamping claw capable of clamping the workpiece. The clamping claw comprises a driven end for clamping and a drive end for applying force. The driven end of the clamping claw is connected with the raised head on the upper surface of the clamping workpiece. The middle of the clamping claw is hinged with the clamping body. The support block is connected with the clamping body through a positioning pin. The cylinder is connected with the clamping body through a strong spring. The toggle rod mechanism comprises an upper toggle rod and a lower toggle rod which are connected with the cylinder body through a roll column and a pin. The top end of the upper toggle rod is hinged with the drive end of the clamping claw. The pneumatic type raised head clamping device provides power through the pneumatic device, achieves constant clamping force and fast clamping, and solves the technical problems that a clamping device in the prior art is slow in clamping and inconstant in clamping force.

Description

technical field [0001] The invention relates to a clamping device, in particular to a pneumatic convex head clamping device. Background technique [0002] The machine tool clamping device is a device used to clamp the workpiece on the machine tool. Its function is to position the workpiece so that the workpiece can obtain the correct position relative to the machine tool or tool, and clamp the workpiece reliably. When clamping, the correct position of the workpiece in the fixture should not be damaged. The clamping force must be appropriate to ensure that the workpiece does not move, rotate, or vibrate during processing, and that the surface of the workpiece will not be damaged due to excessive clamping force. , deformation, the structure should be as simple as possible, the manufacture and maintenance should be convenient, and the operation of the clamping mechanism should be safe, convenient, rapid and labor-saving. Therefore, the clamping device is closely related to the...
