Multi-main-shaft vertical machining center

Abstract

The invention discloses a multi-main-shaft vertical machining center. The center is mainly composed of a plurality of sets of main shaft units, X-direction numerical control sliding tables, Y-direction numerical control sliding tables, Z-direction numerical control sliding tables, rotary tool changers and a set of machine body. According to the machining center, multi-main-shaft synchronous tool changing can be carried out at the same time, and independent compensation can be independently carried out on the length of the tool on each main shaft; and the multi-main-shaft vertical machining center is simple in structure and convenient to maintain, and is ideal drilling and milling comprehensive machining equipment.

Description

technical field [0001] The invention relates to a vertical machining center, in particular to a multi-spindle vertical machining center. 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. Conventional processing centers occupy a large area, and workers have to walk more distances when operating multiple machines, which increases the labor intensity of workers and affects work efficiency; in addition, with the shrinking of land resources, the cost of processing sites is getting higher and higher, so It is hoped that the equipment can be more compact and miniaturized, so as to increase the volume ratio of the workshop and reduce management costs. At present, the machining centers on the market are basically single-spindle structures, wh...

Conventional processing centers occupy a large area, and workers have to walk more distances when operating multiple machines, which increases the labor intensity of workers and affects work efficiency; in addition, with the shrinking of land resources, the cost of processing sites is getting higher and higher, so It is hoped that the equipment can be more compact and miniaturized, so as to increase the volume ratio of the workshop and reduce management costs

At present, the machining centers on the market are basically single-spindle structures, which are relatively inefficient for large-scale processing of some small and medium-sized parts, because only one tool is involved in processing at the same time.

However, although the combination machine tool can participate in the cutting with multiple spindles at the same time and improve the efficiency, its versatility is poor, and adjustment and maintenance are also troublesome.

A Chinese patent discloses a gantry multi-axis machining center (patent number: 201120550910.9). Although it adopts a multi-spindle structure, its tools cannot be automatically replaced, thus restricting productivity

At present, some gantry machining centers on the market adopt a double-spindle structure, but they cannot perform independent compensation for the tool length of the two spindles, which affects the scope of use of the equipment.
