Compound numerically-controlled gantry machine

Abstract

The invention relates to a numerically-controlled machine tool, and provides a compound numerically-controlled gantry machine. The compound numerically-controlled gantry machine comprises a rack, a workbench, a fixing base, a horizontal moving mechanism, a driving unit, a gantry frame, an oblique stand column, a horizontal spindle box, a first vertical spindle box, a second vertical spindle box, ahorizontal tool changer, a first vertical tool changer and a second vertical tool changer, wherein both the horizontal spindle box and the first vertical spindle box are slidingly arranged on a beamof the gantry frame, an outer circumferential side and an inner ring inner circumferential side of a to-be-machined circular knitting machine saddle on the workbench are machined by the horizontal spindle box, an upper end surface of the to-be-machined circular knitting machine saddle on the workbench is machined by the first vertical spindle box, and the second vertical spindle box which can vertically slide on an oblique surface of the oblique stand column is arranged on the oblique stand column to machine a lower oblique ring surface, at the outer circumferential side, of the to-be-machinedcircular knitting machine saddle on the workbench. By means of the compound numerically-controlled gantry machine, the problems of low machining efficiency and high production costs of circular knitting machine saddle workpieces, with multidimensional and multistation requirements, according to existing compound machining centers are solved.

Description

technical field [0001] The invention relates to a numerically controlled machine tool, in particular to a numerically controlled gantry composite machine. Background technique [0002] With the revitalization and development of the national equipment manufacturing industry, CNC machine tools, as the mainstream product of the machine tool industry, have become the key equipment to realize the modernization of the equipment manufacturing industry. In the plumbing, hardware, auto parts, compressors, mobile phone 3C and other industries, with the improvement of market requirements, the demand for high-efficiency, high-reliability and high-automation CNC machine tools is also increasing. The multi-functional machining center is a highly automated mechanical processing equipment. Its characteristics are: it has a tool magazine, which can complete the automatic tool change work. After the workpiece is clamped once, according to the pre-programmed NC machining program, the machining...

Problems solved by technology

In the prior art, machining centers are divided into vertical, horizontal and gantry crane machining centers, all of which are equipped with a main shaft, so only one-sided machining can be realized. Then process the other side of the workpiece, so that it is impossible to process both sides of the workpiece at the same time, and the processing efficiency is low

refer to figure 1 , especially for the processing of the large circular knitting machine saddle 1', it is necessary to process the outer circumference 11' of the saddle 1', the inner circumference inner side 12' of the inner ring, the upper end surface 13' and the lower inclined annulus 14' outside the circumference, It often requires multiple processing centers to cooperate with the processing, the processing efficiency is low, and the processing steps are cumbersome. At the same time, the saddle of the large circular machine is heavy and large, and it is time-consuming and laborious to move back and forth, and the processing cost is high.
