Abstract

The invention discloses a direct transmission type milling machine. The direct transmission milling machine comprises a main shaft and a variable-speed motor; two connecting sleeves embedded with each other are arranged in a seat of the variable-speed motor; an output shaft of the variable-speed motor is in key joint with one connecting sleeve, and the main shaft is in key joint with the other connecting sleeve; and a fixing device which prevents the main shaft and the output shaft of the variable-speed motor from sliding in the axial direction is arranged on the connecting sleeves. The milling machine disclosed by the invention is simple in structure, low in energy consumption, low in failure rate, high in operability and easy to popularize.

Description

technical field [0001] The invention relates to a direct-drive milling machine, which belongs to the technical field of machine tools. Background technique [0002] At present, the milling machine used includes a spindle box, a speed change mechanism, an operating mechanism, an ordinary motor, a shaft coupling, etc., and the speed change mechanism is a set of complex multi-stage gear mechanisms, the structure is relatively complicated, and the clutch is very easy when starting at high speed. damage, the failure rate is extremely high; secondly, due to the limitation of multi-stage gear transmission, the speed of the milling machine spindle can reach up to 1800 rpm; thirdly, multi-stage gear transmission consumes a lot of energy and the motor power loss is large. [0003] Contents of the invention [0004] The present invention aims to provide a direct-drive milling machine with less energy consumption, low failure rate and simple structure. [0005] The object of the pre...
