Right angle calibration block layout method, coordinate calibration method and coordinate adjusting method for gear measurement center

Abstract

The invention provides a right angle calibration block layout method, a coordinate calibration method and a coordinate adjusting method for a gear measurement center. The layout method is to set the right angle calibration block layout fixed on the non-rotary table at a position other than the measurement stroke, and then use the reference template and the right angle calibration block to establish an indirect gear measurement center coordinate calibration method. The coordinate calibration method comprises steps of 1) preliminarily determining the position coordinates of the right angle calibration block in a rotation center; 2) determining the position coordinates of a probe in the rotation center; and 3) accurately determining the position coordinates of the right angle calibration block in the rotation center. The invention solves the problems that the coordinate calibration program in the traditional gear measuring system is complicated, the precision is low, the calculation method is complicated and the requirement for the positioning position of the probe is high; position coordinates of the tangential X axis, the radial Y axis and the vertical Z axis are precisely determined when the right angle calibration block is at the zero point relative to the rotation center; and the position coordinates of the center of sphere of the probe head relative to the measurement system are determined.

Description

technical field [0001] The invention belongs to the technical field of gear precision measurement, and in particular relates to a right-angle calibration block layout method, a coordinate calibration method and a coordinate adjustment method of a gear measurement center. Background technique [0002] Electronic generative gear measuring instrument applied to gear measurement, that is, the gear measurement center is a four-axis measurement composed of a rotary axis Φ and three linear axes (tangential X axis, radial Y axis and vertical Z axis) system, such as figure 1 shown. Different from the general-purpose three-coordinate coordinate measuring machine, in addition to adding a rotary Φ axis and increasing the layout of the upper and lower center tops in the gear measurement center, the probe used to pick up measurement errors is also replaced by a three-coordinate "trigger" probe. "Micrometric" probe. Therefore, the gear measurement center is more suitable for the measure...
