High-precision measuring instrument used in shaft machining process

Abstract

The invention discloses a high-precision measuring instrument used in a shaft machining process. The high-precision measuring instrument comprises a body, a supporting frame is fixedly connected withthe right side of the upper end face of the body; a guide cavity which is through up and down is formed in the supporting frame; a linkage rod is slidably connected into the guide cavity, a sliding groove with a leftward opening is formed in the inner wall of the left side of the guide cavity in a communicating mode, a connecting rod is connected into the sliding groove in an up-down sliding mode,and the connecting rod extends rightwards to be fixedly connected with the left end face of the linkage rod and extends leftwards to the left side of the supporting frame; according to the invention,a to-be-measured shaft is clamped once, the tolerance range of circular runout and straightness of the shaft is directly recorded while the diameter of the shaft is measured, and the measurement synchronism is ensured; the elastic force of a thrust spring enables the measured shaft to abut against the upper end surface of the body, thereby guaranteeing the unified measurement reference; the elastic force of a tension spring enables a measurement rotating wheel to always abut against the outer circular surface of the to-be-measured shaft in a measurement process, which guarantees the measurement accuracy.

Description

technical field [0001] The invention relates to the related field of measuring instruments, in particular to a high-precision measuring instrument used in shaft processing. Background technique [0002] Every time the shaft is measured, the shaft will be re-clamped, so that the benchmarks between the multiple measurement results are not uniform, and the accuracy of each measurement result cannot be guaranteed, so that the relevant data of the shaft cannot be accurately recorded , it will make the follow-up assembly work unable to proceed smoothly, thereby affecting the normal work flow of the entire workshop, thereby greatly reducing the work efficiency of the assembly line. [0003] A high-precision measuring instrument used in the shaft processing process described in the present invention can solve the above problems. Contents of the invention [0004] In order to solve the above problems, this example designs a high-precision measuring instrument used in the shaft pro...
