Embodiment 1

[0065] In this embodiment, a certain axis is taken as an example, and the tooth shape positioning is carried out in a four-axis machining center. The tooth shape of this axis is characterized by a small tooth thickness on both sides and a large middle tooth thickness. , it cannot be finished by conventional methods such as gear shaping, hard hobbing, shaving, grinding, etc., so the final solution is to use a small hob (to avoid interfering with the transition part of the tooth thickness) for rough machining, and then Finishing is done on a machining center with a form milling cutter. Precise gear positioning is required before forming milling cutters for finishing. The tooth profile parameters after rough machining are shown in Table 1:

Abstract

The invention belongs to the field of tooth profile measurement, and discloses a tooth profile positioning method and system. The measuring head is controlled to carry out directional detection, and a series of judgment and conversion are carried out on detection data, so that the central position of the tooth groove is accurately calculated. By means of the tooth profile positioning method, the gear machining precision can be greatly improved, a special positioning tool does not need to be designed, and the machining process flexibility is improved. For batch manufacturing of gear workpieces, the tool investment cost can be greatly reduced, the tooth profile positioning time is shortened, and the machining efficiency is improved.

Description

technical field [0001] The invention belongs to the field of tooth profile measurement, and in particular relates to a tooth profile positioning method and a tooth profile positioning control system. Background technique [0002] The processing of gears is generally completed by multiple processes, such as gear hobbing + fine milling, rough milling + fine milling, hobbing + grinding, etc., which are generally completed by different machine tools. After machining, how to perform precise tooth profile positioning in the second or third process is the most critical step in the finishing process. Or for a multi-gear intermediate shaft, how to ensure that the phases between the gears are accurate, all these require precise tooth profile positioning. [0003] The key to tooth shape positioning is to find the center position of the tooth groove and the coordinates of the rotation axis. The existing technology lacks an effective tooth shape positioning method when the gear is proce...
