Problems solved by technology

[0003] The existing gear grinding process mainly adopts a clamp structure with one clamp and one top, and the outer circle of the parts For positioning, the fixture is supported by the end face of the tooth on the radial plate, and the end face of the lower tooth of the radial plate is pressed and fixed; the lower end of the fixture is fixed to the machine tool, and the upper end of the fixture is supported by the top of the machine tool. Using this type of fixture for the gear grinding process, it is difficult to align the parts. Due to the small tooth width during processing, the teeth are prone to chatter. After processing, the tooth surface quality such as tooth shape and direction is poor, which cannot meet the design requirements, which in turn affects the dynamic unbalance of the parts, thus affecting the safety and service life of the parts.

Abstract

The invention discloses a self-centering anti-vibration clamp for gear grinding processing of a thin radial plate gear part. The clamp comprises a core rod, a taper sleeve and a nut. The core rod sequentially comprises a spherical column, a frustum, a central column and an external thread from bottom to top. The nut is matched with the external thread. The taper sleeve sleeves the central column. The thin radial plate gear part comprises a through hole shaft and a thin radial part gear, wherein the lower end of an inner hole of the through hole shaft is matched with the frustum. The taper sleeve is located between the through hole shaft and the nut, the lower end of the taper sleeve is matched with the upper end of an inner hole of the through hole shaft, and the nut is screwed to fix the through hole shaft between the taper sleeve and the frustum. A bottom center hole and a top center hole are formed in the lower end and the upper end of the core rod respectively, the bottom center hole is used for being matched with a base center of a machine tool, and the top center hole is used for being matched with an upper center of the machine tool. According to the device, the part can be quickly aligned, and vibration is effectively prevented when the part is machined.

Description

technical field [0001] The invention relates to the field of gear grinding fixtures, in particular to a self-centering anti-vibration fixture and a clamping method for grinding teeth of thin web gear parts. Background technique [0002] The design of aero-engine parts is gradually developing in the direction of light weight, heavy load and high speed, which has high production requirements and makes processing difficult. High-performance engine gears have the characteristics of high power-to-weight ratio, high strength, high speed, and high dynamic balance accuracy requirements. Thin web structure is generally used. High standard. Grinding process [0003] The existing gear grinding process mainly adopts a clamp structure with one clamp and one top, and the outer circle of the parts For positioning, the fixture is supported by the end face of the tooth on the radial plate, and the end face of the lower tooth of the radial plate is pressed and fixed; the lower end of the ...
