Embodiment Construction

[0021] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0022] see figure 1 , The preferred embodiment of the present invention provides a method for measuring circular arc end teeth, which is used for measuring the arc end teeth on parts. The measurement steps are as follows: step S10: three-dimensionally scan the circumference of the arc end tooth with a three-dimensional coordinate instrument to obtain corresponding three-dimensional data; step S20: process the obtained three-dimensional data to obtain two-dimensional data, and obtain the arc end Various parameters of the tooth shape.

[0023] figure 2 The three-coordinate measuring instrument used in the method for measuring circular arc end teeth of the present invention is shown. The three-coordinate measuring instrument includes a base 10 , a ...

Abstract

The invention provides a method for measuring a circular arc end tooth, which comprises the following steps of step S10, scanning the periphery of a circular arc end tooth through a three-coordinate measuring instrument in a three-dimensional manner to obtain the corresponding three-dimensional data; and step S20, converting the three-dimensional data into a two-dimensional data to obtain various parameters of a circular arc end tooth shape. The method for measuring the circular arc end tooth measures the circular arc end tooth through the three-coordinate measuring instrument, and the detected three-dimensional data is converted into the two-dimensional data. The method is simpler, and has smaller measurement error, stable measured data and good repeatability; and moreover, the graphic software is utilized to conveniently and directly process the data, and the method is suitable for calibrating various circular arc end tooth gauges and mapping the circular arc end tooth.

Description

technical field [0001] The invention relates to the technical field of measurement, in particular to a method for measuring circular arc end teeth. Background technique [0002] The existing measurement method of the arc end teeth is relatively primitive, especially when measuring the addendum height of the arc end teeth, the arc end teeth can only be measured by placing the arc end teeth on the microscope with the image method, directly using the meter on the differentiation plate of the eyepiece The word line coincides with the profile image of the end teeth to determine the size. However, there are many disadvantages and limitations in measuring arc-end teeth by video method on a microscope: [0003] 1) The tested end tooth is a circular arc surface, not a plane, and the measurement with the image method will cause errors due to the change of the focus distance; [0004] 2) The end teeth under test have rounding or chamfering, which affects the clarity of the end face i...
