Abstract

The invention discloses a clamping device. The middle zone of a workbench is a workpiece positioning zone; the workbench is provided with chutes positioned on the left and the right of the workpiece positioning zone; the workbench is also symmetrically provided with one pair of clamping mechanisms positioned on the left and the right of the workpiece positioning zone; each clamping mechanism comprises a driving device and a fixture fixedly connected with the driving device; the fixture is in sliding fit in the chute on the workbench; a controller used for giving an action order is fixed on the workbench; and the output end of the controller is electrically connected with the driving device of the clamping mechanism. The clamping device is favorable for improving the positioning precision of a workpiece to be processed.

Description

technical field [0001] The invention relates to a tool in the technical field of machining, in particular to a clamping device for clamping a workpiece to be processed. Background technique [0002] When the workpiece is processed in industrial production, in order to ensure the accuracy of the workpiece, it is necessary to fix the workpiece with a clamping device before processing it. The existing clamping device comprises a left clamp and a right clamp, wherein one left clamp is fixed, and the right clamp can move left and right under the drive of the driving device. After the workpiece is placed on the workbench, driven by the driving device, the right fixture moves towards the direction close to the workpiece, clamps and fixes the workpiece together with the left fixture, and then processes it with the tool. Since there is a certain difference in the size of the workpiece, and the distance between the tool machining center and the left fixture is fixed, there is a certa...
