Embodiment Construction

[0033] The present invention is described in further detail below in conjunction with accompanying drawing:

[0034] Such as Figure 1 to Figure 3As shown, a ball roundness and diameter detection device for a stylus of a coordinate measuring machine includes a measuring ball clamping seat 1, the lower end of the measuring ball clamping seat 1 is fixedly connected with the cylindricity measuring instrument workbench 2, and the measuring ball clamping seat 1. The middle part of the upper end is provided with a first measuring club hole 3, and the upper end of the measuring ball clamping seat 1 is located on both sides of the first measuring club hole 3. A second measuring club hole 4 and a third measuring club hole 5 are respectively provided. The axes of the second measuring club hole 4 and the third measuring club hole 5 are symmetrical about the axis of the first measuring club hole 3, and the second measuring club hole 4, the third measuring club hole 5 and the first measuri...

Abstract

The invention discloses a sphere roundness and diameter detection device and method for a probe of a coordinate measuring machine. Three measuring ball rod holes are formed in a measuring ball clamping seat; the axes of the three measuring ball rod holes are in the same plane; the axes of the two measuring ball rod holes are symmetrical about the axis of the other measuring ball rod hole; and theincluded angle between the axes of every two adjacent measuring ball rod holes is 60 degrees. The invention provides a measuring ball clamping seat structure capable of clamping a coordinate measuringball to be measured. Then, the cylindricity measuring instrument workbench is fixedly connected with the measuring ball clamping seat; the three measuring surfaces on the to-be-measured coordinate measuring ball can be directly determined and obtained through the measuring ball clamping seat, so that the measuring ball clamping seat is ensured to be mounted once, the measurement of three mutuallyvertical circular surfaces of the same to-be-measured coordinate measuring ball can be realized, the measuring efficiency is greatly improved, and the interference problem caused by the movement of ameasuring needle of a coordinate measuring machine is avoided.

Description

technical field [0001] The invention belongs to the field of autonomous detection of a measuring ball of a coordinate measuring machine, and in particular relates to a roundness and diameter detecting device and a detecting method for a measuring needle of a coordinate measuring machine. Background technique [0002] Modern metrology is an important technical foundation in national economic construction and national defense construction. Among them, the length measurement in the geometric quantity specialty is closely related to the scientific research, production and assembly quality of the engine, and is the key focus area of ​​the engine quality control. The coordinate measuring ball is the standard device for the calibration of the coordinate measuring machine probe, and its accuracy directly affects the reliability of the measurement results of the coordinate measuring machine. The coordinate measuring balls currently in use are of different sizes and structures, and t...
