Thin-wall gear ring self-centering tensioning installation fixture

Abstract

The invention provides a thin-wall gear ring self-centering tensioning installation fixture. The thin-wall gear ring self-centering tensioning installation fixture comprises a spindle basic disc, a compression disc, a compression nut, a spring and a plurality of tensioning steel balls. The compression nut compresses the compression disc, the compression disc compresses the tensioning steel balls arranged in radial through holes in an annular wall, therefore, the purpose of tightening a thin-wall gear ring from inside to outside is achieved, and radial location of the gear ring is completed. In the process of clamping, the tensioning steel balls evenly distributed on the spindle basic disc are simultaneously stressed, the thin-wall gear ring can receive outward tensioning force evenly, and therefore deformation of the thin-wall gear ring is effectively restrained; meanwhile, the centering performance of the thin-wall gear ring on measurement equipment is guaranteed. The thin-wall gear ring self-centering tensioning installation fixture effectively reduces deformation of the thin-wall gear ring in the process of clamping, eliminates the steps of concentric centering on the measurement equipment after clamping is completed, and improves clamping efficiency and detection accuracy.

Description

technical field [0001] The invention belongs to the field of precision measurement, and in particular relates to a self-centering tensioning installation fixture for a thin-walled ring gear. Background technique [0002] With the continuous development of the machinery manufacturing industry, the precision requirements of the transmission system are getting higher and higher, and the gear is an important part of the transmission system, and its machining accuracy has a great impact on the transmission system. The actual detection results of the gear machining accuracy are often used as It is an important basis for improving the gear processing technology, so the requirements for the actual detection accuracy of the gear are getting higher and higher.

Problems solved by technology

[0003] At present, in the inspection process of thin-walled ring gears, the most commonly used clamping method is to use multi-jaw chucks for clamping, but due to the particularity of its structure, thin-walled ring gears are prone to deformation during the clamping process, and After the clamping on the multi-jaw chuck is completed, it is necessary to perform concentric and horizontal alignment on the measuring equipment. The measurement and clamping process is cumbersome and inefficient, and the deformation of the ring gear will increase the detection error, which will affect the thin-walled teeth.
