Problems solved by technology

Due to the large number of structural parts required by the transmission system, the installation location also has high coordination requirements. Every time the speed is changed, the gears need to be separated and combined, and the equipment is prone to failure.
[0003] Existing machine tools use servo motors as the power source, and the speed adjustment of the servo motor can be used to adjust the final number of revolutions of the machining axis, but the change in the number of revolutions of the servo motor will affect its actual output power, so the adjustment range is limited

Abstract

The invention discloses a milling machine, comprising a spindle box, a first milling shaft, a second milling shaft and a servo motor. The power of the servo motor is transmitted to the first milling shaft and the second milling shaft by a main transmission system. The first milling shaft is a middle transmission shaft between the second milling shaft and the servo motor. The milling machine can lower the cost, simplify the transmission system, ensure low damage possibility of the transmission system, prolong the service life of the machine tool, simultaneously optimize the motor power and savethe energy.

Description

technical field [0001] The invention relates to a milling machine, in particular to a milling machine with two processing axes and a transmission system. Background technique [0002] Mechanical equipment occupies a dominant position in various processing, especially lathes, milling machines, boring machines, planers, grinding machines and other equipment. Now, in order to automate processing, improve processing speed and precision, CNC machine tools have appeared; among the above mechanical equipment, milling machines It is used to process flat parts, and flat processing is often encountered in mechanical processing. In the past milling process, the demand for cutting elements was limited by cutting conditions, such as different materials, different tools used, different tool sizes, different numbers of tools, different characteristics of roughing and finishing, and the cutting speed and spindle transmission The demand for the size of the torque is also different, which re...
