High-rigidity double-spindle vertical machining center

Abstract

The invention relates to a high-rigidity double-spindle vertical machining center. The high-rigidity double-spindle vertical machining center mainly comprises a base, a stand column, a cross numerical control sliding table, Z-direction numerical control sliding tables, main shaft units and tool magazines, wherein an up-and-down adjusting seat is arranged between each Z-direction numerical control sliding table and the stand column; two Z-direction numerical control sliding tables, two main shaft units and two tool magazines are arranged left and right; and the tool magazines are fixedly mounted on the up-down adjusting seats and are arranged on the side surfaces of the main shaft units. The rigidity is high, synchronous tool changing of two main shafts can be carried out simultaneously, and length compensation of tools on the main shafts can be independently carried out; and the high-rigidity double-spindle 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 double-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. In recent years, there have been many vertical machining centers with double spindles on t...

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

In recent years, there have been many vertical machining centers with double spindles on the market. They all adopt the structure of parallel double spindles of traditional vertical machining centers. The structure is as follows: figure 1 As shown, the overhang distance from the main shaft core (101) to the guide rail (102) is very long, resulting in weak rigidity, and this shortcoming is more obvious in the case of dual spindles; resulting in shortened machining efficiency, precision and tool life , not conducive to popularization
