A Positioning and Tool Changing CNC Tool Post Based on Reliability Comprehensive Design

Abstract

The invention relates to the field of numerical control machining, in particular to a positioning tool change type numerical control tool holder based on reliability comprehensive design, which includes horizontally arranged support and guide columns, fixed mounting frames are symmetrically arranged at both ends of the support and guide columns, and the fixed mounting frame The upper ends are provided with fixed installation holes, and a sliding installation cylinder is arranged horizontally in conjunction with the supporting guide column, and a lifting installation plate is horizontally arranged directly below the sliding installation cylinder, and the lifting installation plate and the sliding installation cylinder are connected by an electronically controlled lifting column. The middle position of the lifting installation plate is vertically equipped with a limited rotation sleeve, through horizontal guide displacement adjustment, lifting height adjustment, and rotation displacement adjustment, the working range of the device is significantly improved, and the helical gear coarse adjustment and gear fine adjustment are used to realize positioning. Tool change operation, and the device can preset multiple sets of tools at the same time, the tool change process is continuous and stable, so that the device can greatly improve the efficiency of CNC operations, reduce the frequency of tool change, and at the same time have high tool change accuracy.

Description

technical field [0001] The invention relates to the field of numerical control machining, in particular to a reliability-based comprehensive design positioning tool change type numerical control tool holder. Background technique [0002] CNC machine tool is the abbreviation of numerical control machine tool, which is an automatic machine tool equipped with a program control system. The control system can logically process programs with control codes or other symbolic instructions, decode them, express them in coded numbers, and input them into the numerical control device through the information carrier. After calculation and processing, various control signals are sent by the numerical control device to control the movement of the machine tool, and the parts are automatically processed according to the shape and size required by the drawing. [0003] Chinese patent (Notice No. CN209717025U) discloses a new type of CNC tool post for CNC machine tool processing. Although it ...
