Rough-precise compound numerical control machining center machine tool

Abstract

The invention discloses a rough-precise compound numerical control machining center machine tool which comprises a base, a moving device installed on the base, a worktable movably installed on the moving device, a stand column installed on the back face of the base, a thick-thin double-head composite structure installed on the stand column, a power device and an automatic tool changing device installed on the stand column. According to the rough-precise compound numerical control machining center machine tool, original multi-time clamping can be changed into one-time clamping to complete machining, time is consumed during multiple-time clamping, repeatability of secondary workpiece zero correction is not easy to ensure, the machining precision of a product is affected, and the qualification rate of the product is reduced. According to the rough-precise compound numerical control machining center machine tool, high-speed rough machining and high-speed and high-precision machining can also be achieved while the problems are prevented from happening, two machines are combined into one, the work efficiency is improved, the cost of the enterprise investment can also be greatly reduced, the research and development come from the production practice and the market requirements and conform to the research and development direction, and high practical value is achieved.

Description

technical field [0001] The invention belongs to the mechanical field of numerical control machine tools, and specifically relates to a rough-fine compound numerical control machining center machine tool. Background technique [0002] Through the research on standard CNC machining center machine tools, it is found that the current standard machining center machine tools on the market, in metal cutting processing, large cutting volume, heavy cutting and high-speed high-precision machining cannot be completed on the same machine tool at the same time, the current market standard Advanced roughing machine tool, the main shaft is driven by all gears, with low speed and high noise. The current standard high-speed machines in the market are mostly high in cost and small in chip volume. When using them, rough machining must be carried out first. Often, a machine tool with a hard rail gear drive spindle is used first to rough out parts and components with a large amount of cutting. ...

[0002] Through the research on standard CNC machining center machine tools, it is found that the current standard machining center machine tools on the market, in metal cutting processing, large cutting volume, heavy cutting and high-speed high-precision machining cannot be completed on the same machine tool at the same time, the current market standard Advanced roughing machine tool, the main shaft uses full gear transmission, low speed and high noise

The current standard high-speed machines in the market are mostly high in cost and small in chip volume. When using them, rough machining must be carried out first. Often, a machine tool with a hard rail gear drive spindle is used first to rough out parts and components with a large amount of cutting. For the cutting allowance required for some processing, remove the workpiece and put it into a high-speed, high-precision machine tool for precision high-speed processing

This operation requires 2 times of clamping and calibration, and the investment of 2 machine tools, which is time-consuming and increases the investment of equipment
