Abstract

The invention discloses a gear hobbing tool rest of a small-module numerical control gear hobbing machine, which comprises a tool rest body part, a tool rest main shaft part, a tool rest shifting part and a tool rest tail seat part. The main shaft part of the tool rest includes a slide plate of the tool rest, a spindle box installed on the slide plate of the tool rest, a main shaft pivotally connected in the spindle box, and a knife bar; Torque motor, the rotor of the torque motor is fixed on the main shaft, the stator of the torque motor is installed on the inner wall of the main shaft box; the tool bar is installed on the main shaft. The part of the knife rest that moves is fixed on the slide plate of the knife rest, and the part of the knife rest that shifts the knife is pivotally connected with a screw, and the nut on the screw is fixed on the body of the knife rest. The knife rest tailstock part is slidably fitted on the knife rest slide plate, and the knife rest tailstock part is against the tail end of the tool bar. The rotor of the torque motor of the present invention is directly fixed on the main shaft, which realizes zero transmission of power transmission, avoids transmission errors, and is beneficial to improving the rotation accuracy of the main shaft.

Description

[0001] Technical field: [0002] The invention relates to gear hobbing machine equipment, in particular to a gear hobbing tool holder of a small modulus numerically controlled gear hobbing machine. [0003] Background technique: [0004] For the hobbing tool rest of the small modulus numerical control gear hobbing machine, according to the prior art, the motor transmits power to the main shaft of the hobbing tool rest through the transmission device (such as a gear mechanism) of the intermediate link. Because the transmission device must have transmission errors, the transmission device in the middle link is not conducive to improving the rotation accuracy of the main shaft. [0005] Invention content: [0006] The technical problem solved by the present invention: the hobbing tool holder (machinable worm) of the small modulus numerically controlled gear hobbing machine in the prior art, because the motor transmits power to the main shaft of the hobbing tool holder through the...
