A fully automatic universal CNC machine tool fixture

Abstract

The invention discloses a full-automatic all-purpose numerical control machine tool clamp which adopts a numerical control programming control method and a multi-stepping-motor driving mode, is driven by a precision ball screw, applies a dividable V-shaped positioning block and combines with all-purpose floating chucks to form an all-purpose positioning and clamping structure and achieve efficient clamping under the effect of gas-liquid clamping cylinders. A workpiece is mainly positioned by the dividable V-shaped positioning block driven by stepping motors, the main degree of freedom of the workpiece is limited, and the position of a positioning plane with respect to a machine tool workbench is determined by the stepping motors. The floating chucks driven by the stepping motors complete positioning and clamping tasks of a secondary surface. The full-automatic all-purpose numerical control machine tool clamp consists of a clamp workbench, a left-opening stepping motor, a left-opening ball screw, the dividable V-shaped positioning block, a right-opening ball screw, a right-opening stepping motor, a transverse-moving stepping motor, a transverse-moving ball screw, a left floating chuck, a left chuck body, a left gas-liquid cylinder, a left chuck stepping motor, a left chuck ball screw, a right chuck stepping motor, a right chuck ball screw, a right floating chuck and the like.

Problems solved by technology

However, the current development and use of the high-efficiency, high-precision, and universal CNC machine tool fixtures are far from meeting the needs of enterprises.

The main reason is that the parts to be processed have various structures and shapes, and the processing parts and processing technology requirements are greatly different from the processing parameters, resulting in difficulties in the structural design of universal fixtures and insufficient adaptability, which hinder the development and production of universal fixtures for CNC machine tools
