Problems solved by technology

However, the traditional circular runout measuring instrument is more suitable for measuring the circular runout of large long-axis parts, and for small and medium-sized short-axis parts, the traditional circular runout measuring instrument needs to be equipped with an additional auxiliary support mechanism. The problem of a large number of instrument parts and cumbersome operation steps

Abstract

Provided in the invention is a magnetic attraction fixed table type circular runout measuring device for short shaft parts. The device comprises a base, a rotating platform, a dial indicator and a dial indicator mounting frame. A boss with a cylinder structure is arranged on the upper end face of the base, a workpiece positioning base is arranged in the center of the top of the boss, and a permanent magnet ring is embedded in the upper end face of the boss. The rotating platform is provided with a central hole, the rotating platform sleeves the outside of the boss through the central hole, andone side of the rotating platform is provided with the dial indicator mounting frame; and the dial indicator is fixed on the dial indicator mounting frame, and a measuring head points to the centralaxis of the workpiece positioning base. The device has the advantages of being simple in structure, convenient to operate and accurate in measurement result, and a problem of radial circle run-out measurement of small and medium-sized short shaft parts is solved.

Description

technical field [0001] The invention relates to a measuring device for radial circular runout of a rotary workpiece, in particular to a magnetically fixed table-type radial circular runout measuring device suitable for short shaft parts, belonging to the technical field of testing and measurement. Background technique [0002] The circular runout of the rotary workpiece is a comprehensive error. For example, the radial circular runout of the rotary workpiece includes not only the axis translation, inclination, and bending that cause the coaxiality error, but also the roundness error in the shape error of the same cross section. In order to meet the shape and position tolerance requirements of the rotary workpiece and ensure the machining quality of the workpiece, it is necessary to measure the radial circular runout of the workpiece during the machining process. [0003] The measurement of the circular runout of the rotary workpiece is usually carried out on the circular run...
