Abstract

The invention relates to a clamping device, in particular to a clamping device for a plate-shaped workpiece. The clamping device comprises two pressing plates, a transmission mechanism and substrates provided with a clamping table, wherein the two pressing plates are hook-headed pressing plates oppositely arranged on the two sides of the clamping table; the transmission mechanism comprises a screw, a left rotating block, a right rotating block and two transmission rods; a reset spring is sleeved on each transmission rod; the upper ends of each transmission rods are connected with the hook-headed pressing plates; the middle part of the left rotating block is hinged to the substrate below a hook-headed pressing plate, the upper part of the left rotating block is hinged to the bottom of one transmission rod, and the lower part of the left rotating block is hinged to one end of the screw; the upper part of the right rotating block is hinged to the substrate below the other hook-headed pressing plate, and the middle part of the right rotating block is hinged to the bottom of the other transmission rod; the screw penetrates through the lower part of the right rotating block, the far hinged end of the screw is provided with an adjusting nut, and a sliding sleeve is arranged between the adjusting nut and the right rotating block. The two pressing plates are used for clamping the workpiece simultaneously, and the contact surface between each pressing plate and the workpiece is large, and the workpiece is not easy to be broken by clamping.

Description

technical field [0001] The invention relates to a clamping device, in particular to a clamping device for a plate-shaped workpiece. Background technique [0002] In mechanical processing, it is usually necessary to use a clamping device to clamp the workpiece first, and then process on the workpiece, so the clamping device is widely used. In the clamping device, if there are two pressure plates, it is necessary to ensure that the two pressure plates Simultaneously compress the workpiece. [0003] However, the existing clamping device with two pressure plates has the phenomenon that the clamping of the two pressure plates is not synchronized. In addition, the two pressure plates generally clamp the workpiece from both sides of the plate-shaped workpiece. When the pressure plate clamps the workpiece, the contact between the pressure plate and the workpiece The surface is small, resulting in a large local force on the workpiece, and the workpiece is easily crushed.
