Abstract

A boring head for boring non-circular holes mainly comprises a casing (1), a boring head bearing (2), a hollow shaft (3), a boring tool (4), a boring bar (5), a displacement measuring panel (6), a displacement sensor (7), a spring plate (8), a transitional bar (9), a magnetostrictive rod (10), a non-magnetic material tube (11), a rotary encoder (12), a coil (13), a belt (14), a belt pulley (15), a spindle motor (16), a driver (17) and the like. The driver (17) controls magnitude of field current in the coil (13) to drive the magnetostrictive rod (10) to constrict, and elastic deformation of the spring (8) is changed by the aid of the transitional bar (9), so that the radial position of the boring tool (4) is changed, and the non-circular holes can be bored accurately according to feedbacks of the displacement sensor (7) and the rotary encoder (12).

Description

technical field [0001] The invention belongs to the technical field of numerical control machine tools, in particular to a boring head used for boring non-circular pin holes. technical background [0002] At present, in non-circular boring (such as the processing of non-circular pin holes in pistons), the boring tool is required to perform rapid and accurate micro-displacement movement in the radial direction. In use, a hydraulic mechanism is generally used to control the radial movement of the boring tool, such as Chinese patent CN2532929Y , CN1232732A, etc. The disadvantages of these structures are complex structures, poor precision and stability, and cannot be numerically controlled. [0003] The present invention utilizes the achievement of new materials to invent a mechanism to make the boring tool perform rapid, precise and digital micro-displacement movement along its radial direction, so as to process non-circular pin holes conveniently and practically.
