Embodiment

[0064] Taking the reference cogging as an example, the additional translation of the grinding wheel in the X-axis and Y-axis directions is represented by Δx and Δy respectively, then: Δx = e · sin ( α + β ) Δy = e · cos ( α + β ) , Using the above method, when the CNC form grinding wheel gear grinding machine grinds the involute tooth profile of the large gear, it does not need to install and align...

Abstract

The invention discloses an automatic compensating method of a gear clamping eccentric error of gear grinding of a numerical control (NC) formed grinding wheel. On an X-axis of a numerical control machine, a detection head of a touch sensor is arranged towards one side of a gear, the touch sensor is sequentially connected with an joint plate, an NC system, and a terminal control console at the back side, and the NC system is connected to each operation control part of a machine tool through a servo system. The apparatus is implemented by the following steps of: step 1, carrying out eccentricity detection; and step 2, regulating eccentricity, sending a command to the machine tool through the servo system by the NC system, and horizontally moving the grinding wheel through a Y-axis of the machine tool to enable the symmetric line of the axial section to be overlapped with the symmetric line of a gear groove and enable the grinding wheel to be fed along the radial direction of the gear until the axial section of the grinding wheel shaft is completely coincided with the radial section of the gear groove, and then, finishing the process. The method provided by the invention is simple in steps and high in regulation efficiency.

Description

technical field [0001] The invention belongs to the technical field of numerical control machine tool equipment, and relates to an automatic compensation method for gear clamping eccentric error used for grinding teeth of a numerical control forming grinding wheel. Background technique [0002] The basic principle of tooth grinding by forming method is: use a shaped grinding wheel with the same cross-sectional shape as the tooth groove of the processed gear, make the grinding wheel rotate at high speed and reciprocate along the tooth direction of the gear to complete the grinding of a complete tooth width; the current one After the teeth are ground, grind the second tooth by indexing once. [0003] When the existing CNC form grinding wheel gear grinding machine grinds involute straight teeth and helical gears, the processed gears are installed and positioned on the rotary table of the machine tool. The accuracy of its positioning on the processing machine tool has a direct ...
