Spline tension positioning device for gear machining and detection and installation method thereof

Abstract

The invention relates to a spline tension positioning device for gear machining and detection and an installation method thereof. The spline tension positioning device includes a mandrel, a supportingplate, a spline tensioning sleeve, a set nut and a compression nut; central positioning holes are formed in the upper end and the lower end of the mandrel, and the mandrel is provided with an upper threaded segment, a middle threaded segment and a lower threaded segment, a positioning conical surface is arranged in the position, located between the middle threaded segment and the lower thread segment, on the mandrel, and symmetrical flat milling surfaces are arranged at the lower end of the mandrel; spline tooth shapes are arranged outside the spline tensioning sleeve, and an internal hole ofthe spline tensioning sleeve is a conical hole; a threaded hole is formed in the center of the supporting plate; the supporting plate is connected with the lower threaded segment of the mandrel, andthe spline tensioning sleeve and the mandrel are coaxially connected through the matching of the conical hole and the positioning cone surface in a sleeving mode; and the set nut is connected with themiddle threaded segment of the mandrel, and the lower end of the compression nut is pressed on the upper end of the spline tensioning sleeve, so that a plurality of gear workpieces form tension contact with the spline tensioning sleeve, and the compression nut is connected with the upper threaded segment of the mandrel, so that the multiple gear workpieces are clamped and fixed between the supporting plate and the compression nut. According to the spline tension positioning device for gear machining and detection and the installation method thereof, the phase consistency requirement of innerteeth and outer teeth of gears used in pairs or sets is ensured.

Description

technical field [0001] The invention belongs to the technical field of gear processing, relates to the processing technology of gears with teeth in the inner hole, and specifically designs a spline tightening and positioning device for gear processing and detection and an installation method thereof. Background technique [0002] Sheet gear is an important part of high-precision planetary reducer. The inner hole of the gear is provided with a tooth shape, and the gear machining accuracy is high, especially for gears used in pairs or sets. The inner tooth shape and the outer tooth have strict requirements. phase requirements. The existing processing method is single-piece processing, and its mechanical processing and shape measurement process often use cylindrical mandrels, tapered mandrels or spline shafts for positioning. The operation process involves multiple alignment problems, which is not conducive to improving mass production. Processing efficiency in production mode...
