Embodiment 1

[0035] see Figure 5 , the measuring instrument is the polar coordinate gear measuring center. Using a one-dimensional needle-point probe, the measuring force is perpendicular to the R direction, and the offset of the probe is T 0 A known. Utilize the concrete steps of the inventive method to be:

[0036] The first step: Clamp the standard block on the rotary axis table of the polar coordinate gear measurement center, and place the measuring head in a suitable position in the R and Z directions, so as to ensure that the standard block can make a datum under the drive of the turntable Surface contact with the upper probe;

[0037] Step 2: Driven by the rotating shaft of the polar coordinate gear measurement center, the standard block is brought into contact with the probe, so that the reference plane A of the standard block is 1 Touch the upper probe; obtain the coordinate values ​​of each axis of the contact point on the standard block (R 1 ,q 1 );

Abstract

The invention relates to a method for realizing the zero point calibration of the polar coordinate gear measurement center by using a standard block. At present, there is no zero point calibration for the polar coordinate measurement center, nor for T 0 There is no device and method for automatic detection, so subsequent measurement software cannot be used for automatic error compensation. The present invention realizes the zero point calibration of the polar coordinate gear measurement center with a standard block, the standard block used includes a mandrel and two datum planes, the standard block is installed on the rotary shaft of the polar coordinate gear measurement center through the mandrel, and the two datums Face is A 1 and A 2 , and the distances between the two sides relative to the center of the mandrel are B 1 and B 2 . The standard block used in the present invention is essentially a standard block with a mandrel, and only needs to ensure the straightness of the two sides during processing; one-time clamping can realize automatic zero point calibration; it is also suitable for known gear measurement centers .

Description

technical field [0001] The invention belongs to the technical field of coordinate measuring machines, and in particular relates to a method for realizing zero point calibration of a polar coordinate gear measurement center by using a standard block. Background technique [0002] The gear measuring center is the crystallization of the integrated application of information technology, computer technology and numerical control technology on gear measuring instruments, and it is a milestone in the development of coordinate gear measuring instruments. It is mainly used for the detection of single geometric accuracy of gears, and can also be used for the measurement of the overall error of gears.
