According to the eccentricity measuring instrument, a bottom face of a measuring body is provided with a recess, one side face of the measuring body is rotatably connected with a T-shaped sleeve, the other end of the measuring body is provided with a disposing hole for an indicating gauge, the bottom portion of the indicating gauge is provided with a connection rod, the other end bottom face of the connection rod is provided with a side head, the other end side face of the measuring body is provided with a fastening bolt used for fixing the indicating gauge, the bottom end of the T-shaped sleeve is provided with a upward groove, two sides of the groove are provided with through holes, the groove is internally provided with a double-piston-rod oil cylinder, and piston rods at two ends of the double-piston-rod oil cylinder correspond to the through holes at two sides of the groove. Through the eccentricity measuring instrument, eccentricity values of workpieces can be accurately measured, and the measuring precision is improved.
Description
technical field [0001] The invention relates to the technical field of workpiece measuring devices, in particular to an eccentricity measuring instrument. Background technique [0002] At present, to check whether the eccentricity is qualified, a special set of eccentric plug gauges is generally produced; however, this eccentric plug gauge has the following disadvantages: 1. The specific eccentricity value cannot be accurately measured; 2. For workpieces with high precision requirements, Detection accuracy cannot be guaranteed. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide an eccentricity measuring instrument that can accurately measure the value of the eccentricity and improve the measurement accuracy. [0004] The technical scheme of the present invention is as follows: [0005] An eccentricity measuring instrument, including a measuring body, the bottom of the measuring body is provided with a depression; one side of the measurin...
