Clamp for numerical control machine tool

Abstract

The invention relates to the technical field of numerically-controlled machine tools, in particular to a clamp for a numerically-controlled machine tool which comprises a clamp body. The clamp body includes a work box, the top surface of the work box is provided with a square working platform, round through holes are drilled in the left side and the right side of the working platform, and the working platform is provided with a cross processing platform. Square fixing supporting plates are mounted at the middle of the front and rear ends of the cross processing platform, and fixed by screws. An air pump is disposed on a middle portion inside the work box, square supporting tables are correspondingly arranged on the left side and right side in the work box, vertical cylinders are mounted onthe two square supporting tables respectively, and cylinder shafts of the two vertical cylinders pass through the round through holes formed in the two sides of the working platform and are connectedwith square movable plates. According to the clamp for the numerically-controlled machine tool, a double-layer clamping mechanism is adopted, and a compatible clamping head is adopted. The clamp hasa quick clamping speed, greatly shortens unit processing unit and improves work efficiency.

Description

technical field [0001] The invention relates to the technical field of numerical control machine tools, in particular to a fixture for numerical control machine tools. Background technique [0002] CNC machine tools are mainly used for cutting the inner and outer cylindrical surfaces of shaft parts or disk parts, the inner and outer conical surfaces of any cone angle, complex rotary inner and outer curved surfaces, cylinders, and conical threads, etc., and can perform grooving, drilling, and reaming. , Reaming and boring etc. It is to automatically process the processed parts according to the pre-programmed processing program. We write the processing route, process parameters, tool trajectory, displacement, cutting parameters and auxiliary functions of the parts into a processing program sheet according to the instruction code and program format specified by the CNC machine tool, and then record the contents of the program sheet On the control medium, it is then input into...

AI Technical Summary

Problems solved by technology

[0003] However, in the actual workshop work, when drilling, reaming, reaming and boring, etc., the workpiece to be processed is often a cylindrical workpiece or a square workpiece. When holding the workpiece, it is troublesome and inconvenient to mainly replace different fixtures, which greatly affects the processing speed and prolongs the unit processing time, which is not conducive to the improvement of production efficiency.

In addition, due to the different heights of the workpieces to be processed, the traditional fixtures are not stable when clamping, which affects the later processing and leads to waste products
