Problems solved by technology

[0002] At present, for workpieces with eccentric holes, it is generally troublesome to measure the eccentric distance. When measuring, it is generally necessary to use a special shaft that is the same size as the hole diameter to extend into the workpiece, and then rotate the workpiece. This method of measurement is cumbersome to operate, and it is necessary to design a shaft suitable for the hole. The accuracy of the shaft has a certain influence on the measurement result, which leads to the poor applicability of workpiece measurement. In addition, during operation, sometimes It is very difficult to rotate the workpiece and it is difficult to measure the workpiece accurately

Abstract

The invention discloses an inner hole eccentricity measurement device. The eccentricity measurement device of the invention is convenient and reliable for measurement, and is suitable for measurement of eccentric holes of various diameters, and the measurement is accurate. Position the support plate, and make the inner hole centering component sleeve in the eccentric hole, then rotate the handle to make the screw rotate, so that the centering head is clamped against the inner wall of the eccentric hole to realize the automatic centering of the eccentric hole of the workpiece function, after that, put the eccentricity measurement component against the outer circumference of the workpiece, rotate the rotating disk for one circle, and calculate the eccentricity by the maximum runout measured by the eccentricity measurement component.

Description

technical field [0001] The invention relates to an inner hole eccentricity measurement device, which belongs to the technical field of inner hole eccentricity measurement equipment. Background technique [0002] At present, for workpieces with eccentric holes, it is generally troublesome to measure the eccentric distance. When measuring, it is generally necessary to use a special shaft that is the same size as the hole diameter to extend into the workpiece, and then rotate the workpiece. This method of measurement is cumbersome to operate, and it is necessary to design a shaft suitable for the hole. The accuracy of the shaft has a certain influence on the measurement result, which leads to the poor applicability of workpiece measurement. In addition, during operation, sometimes It is very difficult to rotate the workpiece, and it is difficult to measure the workpiece accurately. [0003] In view of the above problems, the present invention provides an inner hole eccentricit...
