Abstract

The invention discloses a hobbing tool rest for a small-modulus numerically-controlled gear hobbing machine. The hobbing tool rest comprises a tool rest body, a tool rest main shaft, a tool rest tool movement part and a tool rest tailstock, wherein the tool rest main shaft comprises a tool rest sliding plate, a main shaft box installed on the tool rest sliding plate, and a main shaft body and a tool bar which are pivoted in the main shaft box, the tool rest sliding plate is arranged on the tool rest body in a sliding fit mode, a torque motor is arranged in the main shaft box, a rotor of the torque motor is fixed to the main shaft body, and a 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 body; the tool rest tool movement part is fixed to the tool rest sliding plate, a lead screw is pivoted to the tool rest tool movement part, and a nut of the lead screw is fixed to the tool rest body; the tool rest tailstock is arranged on the tool rest sliding plate in a sliding fit mode, and the tool rest tailstock abuts against the tail end of the tool bar. Due to the fact that the rotor of the torque motor is directly fixed to the main shaft body, direct power transmission is achieved, transmission errors are avoided, and the rotating precision of the main shaft body is improved.

Description

Technical field: [0001] 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. Background technique: [0002] 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. Invention content: [0003] 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 transmission device of...
