Abstract

The invention relates to a vertical machining center, in particular to a high-rigidity large-torque vertical machining center. The machining center mainly solves the technical problems that high-grade and low-grade reduction boxes are high in price, high speed gears operate in ultimate states, the failure rate is high, the use and maintenance costs are high, the machining requirements of other reduction ratios such as 1:2 / 1:3 cannot be met, the rigidity of a spindle is poor, and the tool changing failure frequency is high in vertical machining in the prior art. The machining center comprises a honeycomb type bed, wherein a double-layer ribbed carriage and a workbench are arranged on the honeycomb type bed; a herringbone frame upright is also arranged on the bed and connected with a spindle box by a guide rail in a sliding manner; a ball screw is arranged on the herringbone frame upright; the spindle box is in threaded connection with the ball screw; a tool magazine and an unclamping cylinder is arranged on the spindle box; the spindle box is internally provided with a 1:2 / 1:4 / 1:8 speed reducer; a spindle location device is arranged on a spindle of the spindle box; and the vertical machining center is provided with an electric and numerical control system.

Description

technical field [0001] The invention relates to a vertical machining center, in particular to a high-rigidity and high-torque vertical machining center. Background technique [0002] The existing machining center has poor rigidity of the machine tool spindle device; when the spindle speed is lower than the rated speed, the power of the main motor decreases proportionally with the speed drop, resulting in poor cutting efficiency and energy waste. [0003] Existing machining centers are mainly used in the processing of non-ferrous metal parts, ferrous metal parts, and new difficult-to-machine material parts. In order to improve the machining accuracy and cutting efficiency of parts, the existing technology is developing in the direction of high speed and high precision. The spindle speed is generally 8000- 15000rpm, the electric spindle can reach more than 80000rpm; but the cutting torque and effective power are small at low speed, which cannot meet the requirements of rough m...
