Grinding machine workbench fixing device

Abstract

The invention discloses a grinding machine workbench fixing device which comprises a mounting table base. A fixing assembly is mounted on the front portion of the top end of the mounting table base, a rear edge abutting assembly is mounted on the rear portion of the mounting table base, a side edge abutting assembly is mounted on one side of the mounting table base, a fixing sliding groove is formed in one side of the top end of the mounting table base, a lateral sliding groove penetrating to the fixing sliding groove is formed in the side face, close to the fixing sliding groove, of the mounting table base, and limiting protruding blocks in a linear array are fixedly connected to the position, located below the lateral sliding groove, of the side face of the mounting table base. By arranging the adjustable fixing assembly, the rear edge abutting assembly and the side edge abutting assembly, clamping can be conducted according to the sizes of liquid crystal glass, and the device is flexibly suitable for wider liquid crystal glass grinding work; and a second spring and fourth springs are arranged, certain proper buffering is provided for clamping force, and workpiece damage or quality reduction caused by too large clamping force is prevented.

Description

technical field [0001] The invention belongs to the field of ground glass, in particular to a workbench fixing device for a grinding machine. Background technique [0002] In the production process of TFT-LCD (liquid crystal display) glass substrate, the glass substrate will go through the grinding process. The glass substrate has high requirements on the surface quality. The traditional clamping method may cause glass deformation, and may damage the liquid crystal glass in severe cases. There is no way to flexibly adjust the clamping according to the size of the glass in the customized grinder. Therefore we make improvement to this, propose a kind of grinder workbench fixing device. Contents of the invention [0003] The purpose of the present invention is to overcome the above problems existing in the prior art, and to provide a grinding machine table fixing device, which can be installed according to the size of the liquid crystal glass by being provided with an adjust...
