Abstract

The invention discloses a bidirectional rotary electric cutter rest. The bidirectional rotary electric cutter rest comprises a box body, a cutter head, a gear shaft, a rotary shaft, a roller carrier, an outer gear ring, an inner gear ring which is sleeved on the rotary shaft, a motor which can rotate forwardly and reversely, and a clamping gear ring which can be meshed with the inner gear ring and the outer gear ring, wherein a gear is sleeved on the gear shaft; the motor drives the gear shaft to rotate; the gear is meshed with the roller carrier; the roller carrier is supported on the rotary shaft rotatably; the clamping gear ring is moveably sleeved on the rotary shaft through a key; the inner gear ring is fixedly connected with the cutter head; the outer gear ring is fixedly connected with the box body; the bidirectional rotary electric cutter rest also comprises a primary positioning pin; the back end surface of the clamping gear ring is a step plane; a roller which can roll along the back end surface of the clamping gear ring is installed inside the roller carrier; a key slot which is matched with the key is formed on the roller carrier; and a plurality of primary positioning slots which are matched with the primary positioning pin are formed on the clamping gear ring. The bidirectional rotary electric cutter rest is high in locking speed and locking stability and low in noise.

Description

Technical field [0001] The invention relates to a two-way rotary electric tool post, which is used on an automatic rotary turret of a numerical control machine tool. Background technique [0002] At present, the automatic rotary turret of CNC machine tools is driven by a servo motor, and adopts the structure of the motor positive conversion position, coarse positioning limit, and motor reverse locking. Due to the uncertainty of the load and the error in the machining of the parts, plus the difference in electrical control, in order to ensure the reliable operation of the tool post, a certain amount of overshoot is required for the cutter head when the tool is changed forward, that is, the rough positioning pin faces straight and The positioning groove should be separated from the straight face for a certain distance. When the tool post is locked, the coarse positioning pin is pressed down under the action of the spring, and the cutter head and cutter head accessories, tools and ...
