Problems solved by technology

[0003] The disadvantage of the existing technology is that when the main shaft of the vertical servo turret tool post is used horizontally and the main shaft of the horizontal tool post is used horizontally, in the event of a sudden power failure, due to the influence of the large eccentric load of the tool, the tooth plate is passively disengaged , the tool deviates from the original working position, and the position information of the tool is inconsistent with the information recorded by the CNC system, which may easily lead to a collision accident, or even damage the tool holder, resulting in large economic losses

Abstract

The invention discloses a power-off protection device for a servo turret. The power-off protection device for the servo turret comprises a fixed fluted disc, a movable fluted disc, a cutter rest, a shaft and a duplex fluted disc. Multiple cutters are installed on the cutter rest. Annular steps are arranged on the fixed fluted disc and comprise a movable fluted disc annular step and a shaft annular step. A toothed ring is distributed on the upper end face of the movable fluted disc. The duplex fluted disc is fixed to the annular end of the shaft. The cutter rest is fixed to the end face of the duplex fluted disc. The duplex fluted disc is meshed with the movable fluted disc and provided with an inward-protruding ring. A boss is arranged on the outer end face of the shaft. The inward-protruding ring is located on the lower bottom end face of the boss. Installation hole seats are evenly distributed at the upper surface end of the inward-protruding ring. Shaft installation hole seats are formed in the lower bottom end face of the boss correspondingly. Elastic pieces are arranged on the installation hole seats. One end of each elastic piece is arranged in and abuts against the corresponding installation hole seat and the other end of each elastic piece is arranged in and abuts against the corresponding shaft installation hole seat. The power-off protection device is simple and compact in structure and low in production cost.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a power-off protection device for a servo turret tool rest. Background technique [0002] The servo turret tool post is an important functional part of CNC lathes, especially suitable for large horizontal lathes and CNC vertical lathes. It is directly driven by the servo motor, the end tooth plate is used as the indexing element, and the brake is tightened and released by hydraulic control. [0003] The disadvantage of the existing technology is that when the main shaft of the vertical servo turret tool post is used horizontally and the main shaft of the horizontal tool post is used horizontally, in case of a sudden power failure, due to the influence of the large eccentric load of the tool, the tooth plate is passively disengaged , the tool deviates from the original working position, and the tool position information is inconsistent with the information recorded ...
