Abstract

The invention discloses a novel compensating device for a boring cutter, which comprises a machine tool bed (1) and an orifice restriction type high-speed precision liquid static pressure boring head (7), wherein a main shaft drive motor (3), a main shaft pulse coder (6), a workpiece clamping mechanism (11), a workpiece positioning mechanism (12), a numerical control device (13), a longitudinal servo motor drive system (15) and an automatic lubricating device (2) are arranged on the arranged on the machine tool bed (1); the main shaft drive motor (3) is connected with the orifice restriction type high-speed precision liquid static pressure boring head (7); and a super magnetostriction actuator, a super magnetostriction actuator cooling device (4) and a power distribution device of the supper magnetostriction actuator are arranged in a main shaft (20) of a machine tool. The novel compensating device for the boring cutter has the characteristic that the axial displacement generated by the super magnetostriction actuator is transformed into the radial translation displacement of the boring cutter through an L-shaped right angle lever and a four-link combined flexible hinge mechanism,thus the radial translation feeding of the boring cutter is realized.

Description

technical field [0001] The invention relates to a novel boring tool compensation device, which can be used for tool wear compensation and boring diameter adjustment in the boring process, and can also be used for precision boring of special-shaped pin holes of pistons. Background technique [0002] At present, domestically and internationally, there are five representative methods for realizing boring tool compensation, and these methods all have some shortcomings: [0003] Patent No.: 98112446, Publication No.: 1232732A Chinese patent discloses a "special-shaped pin-hole boring device", which adopts the mechanical mechanism of "longitudinal stepping motor + driving rod + push rod", the machine tool structure is relatively complicated, and It is not suitable for the application of high-response tool compensation. [0004] Patent No.: 200510044793, Publication No.: 1743111A Chinese patent discloses "a boring machine for machining special-shaped curved surface holes", which h...
