Embodiment Construction
[0024] A fast pitch circle positioning device for internal spline gears in this embodiment, such as Figure 1 ~ Figure 3 As shown, it includes a cylinder 2 and a cage 5 that can accommodate the internal spline gear 1. The cylinder 2 is fixed on the machine tool. There are three sections of the same arc-shaped notch 3 evenly distributed on the inner wall of the cylinder 2; the cage 5 is set On the top of the cylinder 2, the lower part of the cage is flexibly hung with three ball strings evenly distributed along the circumferential direction, including two ball strings 4. The ball strings are respectively covered by three arc-shaped notches 3 and their corresponding internal spline gears. 1; the diameter of the ball 4 satisfies 2N>da, and N<M, where N is the distance from the center of the internal spline gear 1 to the outermost end of the ball 4, and da is the tooth top of the internal spline gear 1 The diameter of the circle, M is the distance from the center of the inner spli...

Abstract
The invention provides an internal spline gear pitch circle quick positioning device and a machining method of the internal spline gear pitch circle quick positioning device. The internal spline gear pitch circle quick positioning device comprises a round barrel capable of containing an internal spline gear and a retaining frame, wherein three sections of identical arc notches are evenly distributed in the inner wall of the round barrel, the retaining frame is arranged at the top of the round barrel in a sleeved mode, thee ball clusters which are evenly distributed in the circumferential direction of the retaining frame are flexibly hung at the lower portion of the retaining frame, each ball cluster at least comprises a ball, and the ball clusters are respectively clamped by the three sections of arc notches and corresponding tooth sockets of the internal spline gear. The internal spline gear pitch circle quick positioning device can rapidly align and position a pitch circle of the internal spline gear, then machines an internal spline based on the pitch circle, reduces the deviation between the axis of the tooth profile and the axis of the internal spline caused by heat treatment distortion, improves production efficiency, is simple in structure and is convenient to use.
Description
technical field [0001] The invention belongs to the technical field of gear processing machinery, and in particular relates to an internal spline gear pitch circle rapid positioning device and a processing method thereof for gears with an internal spline structure. Background technique [0002] The internal spline gear is installed on the rotating shaft through the internal spline, and the meshing transmission is carried out by the contact of the gear teeth. Therefore, the design and manufacture of the internal spline gear must ensure that the gear tooth profile axis is consistent with the internal spline axis. Since the teeth of the gear will be deformed after heat treatment, in order to make the tooth shape axis consistent with the installation axis, usually after heat treatment, the pitch circle of the gear will be aligned, and then the internal spline will be positioned and processed by the pitch circle. However, in the prior art, the process of aligning and positioning ...
