Abstract

The invention discloses a direct drive type servo knife rest, which comprises an outer shell, a torque motor, a disc-shaped connecting piece, a main shaft, a movable toothed disc, a fixed toothed disc and a locking toothed disc. The knife rest is directly driven by the torque motor; the torque motor is located at the rear end of the knife rest; a torque motor stator is fixed on the outer shell through a screw bolt; a torque motor rotor is fixed with the rear end of the main shaft through the disc-shaped connecting piece; the moveable toothed disc is fixed with the front end of the main shaft;the fixed toothed disc is fixed on the outer shell through a screw bolt; and the locking toothed disc is sleeved on the main shaft and forms a triple toothed disc mechanism together with the movable toothed disc and the fixed toothed disc. The knife rest disclosed by the invention has the advantages of simple and compact structure, small occupied space, low maintenance cost, high transmission efficiency, smoothness in operating and low noise.

Description

technical field [0001] The invention belongs to the technical field of tool holders for numerically controlled machine tools, in particular to a direct-drive servo tool holder. Background technique [0002] Turning machining centers and turning-milling compound machining centers are important processing equipment in aviation, aerospace, military and other industrial fields. The CNC tool post is the core functional component of the turning machining center and the turning-milling compound machining center. Its performance and structure directly affect the cutting performance and cutting efficiency of the machine tool, reflecting the design and manufacturing level of the machine tool. The basic functions of the tool post: one is to fix the tool, and the other is to realize automatic tool change. According to the driving method for tool change, the tool post can be divided into manual tool post, electric tool post (common motor drive), hydraulic tool post (hydraulic motor driv...
