Abstract

The invention discloses a workpiece clamping and fixing device. The device comprises a moving assembly and a fixed assembly, the moving assembly comprises a moving frame, a buffering piece and a positioning piece, and the buffering piece and the positioning piece are arranged on the moving frame; the fixed assembly is arranged on the moving frame and comprises a fixed frame, an air cylinder arranged in the fixed frame, a connecting rod connected with the air cylinder and a clamping hand movably connected with the connecting rod; and the workpiece clamping and fixing device can have up-down floating and clamping functions and can have wide adaptability when clamping workpieces of different models, the modification cost is reduced by changing the specification and model of a clamp instead of a clamping device, the modification difficulty is reduced, the working efficiency is improved, subsequent transformation only needs to input resources in the specification and shape of the clamp, and subsequent maintenance and upgrading are facilitated.

Description

technical field [0001] The invention relates to the technical field of industrial equipment, in particular to a workpiece clamping and fixing device. Background technique [0002] A processing machine tool is a milling machine, drilling machine or lathe that cuts a workpiece. Furthermore, the processing machine tool can also be an assembly machine tool. A workpiece, such as a piston rod or a connecting rod, is held in place by a workpiece clamping device while it is being machined by the machining machine. For example, the workpiece holding device is a workpiece table, which has one or more workpiece receiving seats, which can be swiveled within the working range of the processing machine tool. [0003] The workpiece holders must be adapted to the respective workpiece type. For example, stop blocks are provided on the workpiece clamping device, which form workpiece receptacles and clamp the workpiece. If another type of workpiece is to be processed, then either the entir...
