Double-tool-magazine machining center

Abstract

The invention relates to a double-tool-magazine machining center. The double-tool-magazine machining center is characterized in that the double-tool-magazine machining center comprises a milling machine body, the milling machine body is provided with a Y-direction linear rail, a Y-direction screw and a standing column, wherein the Y-direction linear rail is provided with a cross slide plate, the lower end of the cross slide plate is matched with the Y-direction screw, the Y-direction screw is driven to rotate by power, the cross slide plate is provided with an X-direction linear rail and an X-direction screw, a working table is arranged on the X-direction linear rail, the lower end of the working table is matched with the X-direction screw, the X-direction screw is driven to rotate by power, a workpiece is arranged on the working table, a standing column screw is arranged in the standing column and provided with a lifting block, the front side of the lifting block is connected with a spindle box, a spindle servo motor and 4-8 spindles are arranged on the spindle box, the output shaft of the spindle servo motor is connected with an upper spindle belt wheel and a lower spindle belt wheel, a spindle driven wheel is arranged on each spindle, the upper spindle belt wheel and the lower spindle belt wheel drive 2-4 spindle driven wheels to rotate through spindle belts, a left tool magazine is arranged on the left of the standing column, a right tool magazine is arranged on the right of the standing column, and each of the left tool magazine and the right tool magazine comprises a transmission conveying device, a milling tool storage and fixing device and a milling tool clamping and conveying device.

Description

technical field [0001] The invention relates to a machining center, in particular to a machining center with double tool magazines, which is mainly used for milling machines. Background technique [0002] Existing milling machines usually have only one tool magazine. When changing tools, the manipulator of the tool magazine can only grab one tool at a time, and first clamp the used tool on the spindle of the milling machine and put it on the tool magazine chain. Then clamp the unused tool in the tool pocket of the tool magazine chain, and finally put it on the spindle of the milling machine. If the milling machine processes multiple workpieces at the same time, the manipulator must reciprocate several times every time the tool is changed. To complete the tool change, the tool change speed is slow and the work efficiency is reduced. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art, and provide a machin...
