Abstract

The invention relates to the technical field of machine tool equipment, and discloses a clamping and fixing device for a numerical control machine tool. The device comprises a machine body. A workbench is fixedly installed at the middle of the upper surface of the machine body. A support is fixedly installed at the middle of the periphery of the machine body. A hydraulic device is fixedly sleevedwith the support. According to the clamping and fixing device for the numerical control machine tool, by arranging shorter symmetrically-arranged second fixing plates and a movable fixing plate cooperatively and arranging longer symmetrically-arranged first fixing plates cooperatively, the lower portion of a regular workpiece placed on the upper surface of the workbench can be completely wrapped by the first fixing plates, the regular workpiece and the movable fixing plate, the degrees of freedom of the regular workpiece in the four directions can be limited, an exhaust machine is used for performing exhaust in cooperation with negative pressure holes to form negative pressure, downward force is executed to the regular workpiece, the degrees of freedom in the vertical direction are controlled, and therefore the numerical control machine tool can clamp the regular workpiece more fixedly.

Description

technical field [0001] The invention relates to the technical field of machine tools, in particular to a clamping and fixing device for a numerically controlled machine tool. Background technique [0002] Numerical control machine tool is the abbreviation of digital control machine tool, which is an automatic machine tool equipped with a program control system, which can logically process programs with control codes or other symbolic instructions, and decode them, using coded numbers Said that processing parts on CNC machine tools mainly depends on the processing program. CNC machine tools are suitable for occasions where the processed parts are frequently replaced, that is, suitable for single-piece, small-batch production and new product development, thereby shortening the production preparation period. , which saves a lot of process equipment costs. After the workpiece copper drum die-casting process is formed, the workpiece needs to be further processed. [0003] During...
