The milling cutter mechanism is installed on the carriage through the middle carriage, and a milling cutter and a milling cutter driving motor are arranged on the upper part of the milling cutter mechanism. The milling cutter mechanism is fixedly installed on the middle carriage by bolts.

A shift fork corresponding to the sliding gear and a handle for driving the shift fork are also arranged on the headstock. The driving sprocket is fixedly connected with the driving pulley through pins and screws. The driven sprocket is connected with the drive shaft of the X-direction feed system in the headstock headstock through the end cover.

The beneficial effects of the present invention are: the milling system for lathes, which adds a set of transmission mechanism and milling tool mechanism to realize the milling function on the existing ordinary lathe, and uses the external sprocket chain mechanism to carry out Drive, it can not only realize the function of the original lathe, but also realize the milling of the keyway on the shaft with keyway; its structure is simple, easy to use, expand the function of the machine tool, and greatly save the processing cost of shaft parts with keyway .

Detailed ways

The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

As shown in Figures 1 and 2, the described milling system for a lathe includes a bed 6 and a headstock headstock 5, the headstock headstock 5 is provided with a main motor 1, and the main motor 1 passes through a power output shaft The driving pulley 2 and the driven pulley 3 on the bed are connected with the friction clutch 4 in the headstock 5, and the carriage 8 on the bed 6 is connected with the X-direction feed system in the headstock 5. Its characteristic is that it also includes The milling drive motor 14 that is arranged on the headstock headstock 5 and the milling tool mechanism 10 that is arranged on the carriage 8, the power output shaft of the milling drive motor 14 is provided with an internal connection with the rear end of the main motor power output shaft. The sliding gear 16 meshed with the gear 18, the driving sprocket 21 is fixedly installed on the outside of the driving pulley 2, the driving sprocket 21 is connected with the driven sprocket 23 through the chain 22, and the driven sprocket 23 is connected to the bedside headstock 5.
