Clamping device of molds of engraving-milling machines

Abstract

The invention discloses a clamping device of molds of engraving-milling machines. The clamping device comprises sliding rails, air cylinders, sliding blocks, clamping plates, butterfly-shaped screws and a machine tool, wherein the sliding rails are welded to the machine tool; the sliding rails are provided with four uniform clamping sets, each clamping set comprises one sliding rail, one air cylinder, one sliding block and one clamping plate, the air cylinders are arranged on the machine tool through bolts and are located at the right ends of the sliding rails, the sliding blocks are erected on the sliding rails in a sliding mode, are respectively of a U shape and are connected to piston rods of the air cylinders through bolts, the left end of each sliding block is connected to one clamping plate through one butterfly-shaped screw, and the clamping plates are arranged on the upper surfaces of the sliding rails. The clamping device has the advantages that time and labor are saved and clamping is stable and firm.

Description

technical field [0001] The invention relates to a clamping device, in particular to a clamping device for an engraving and milling machine mold. Background technique [0002] The clamping device of the traditional engraving and milling machine is to manually install the mold on the clamping device. Since the stability of the mold is very important in the process of engraving and milling, the stability of the mold cannot be guaranteed by manual force. Therefore, workers need to work hard to fix the mold on the mounting device, and sometimes the mold will be damaged if too much force is used. The traditional clamping mechanism can only clamp a specific shape of engraving and milling products. When changing the shape of engraving and milling products, It is very troublesome to replace and replace the clamping device. Contents of the invention [0003] In order to solve the defects of the existing technical solutions, the invention discloses a clamping device for engraving an...
