AI Technical Summary

Technical Problem

In the existing technology, the moving and fixed gratings of electronic digital micrometers are not easy to disassemble and assemble for accuracy testing, resulting in low testing efficiency and the testing method is not widely used.

Method used

An electronic digital micrometer moving and fixed grid accuracy testing device was designed, including components such as fixed grid seat, threaded sleeve, rotating shaft, positioning sleeve, moving grid seat, guide screw and spring. The device realizes independent testing of moving and fixed grid through scale and display, and uses the scale to convert angular displacement into linear displacement and display the data.

Benefits of technology

It enables rapid assembly and disassembly of moving and fixed grids and batch testing, improving the accuracy and efficiency of testing.

Abstract

The invention discloses an electronic digital display micrometer movable and fixed gate precision detection device and method, and the device comprises a front fixed gate seat and a rear fixed gate seat, and a threaded sleeve, and a rotating shaft is disposed in the fixed gate seat and the threaded sleeve in a penetrating and screwing manner. A positioning sleeve and a movable gate seat are fixedly mounted and sleeved on the rotating shaft on the front side of the fixed gate seat front and back, a guide screw is screwed on the movable gate seat, the guide screw is in sliding fit in a V-shaped guide groove axially formed in the rotating shaft, and a spring is pressed on the rotating shaft between the movable gate seat and the positioning sleeve; a movable grid and a fixed grid are respectively mounted on the opposite end surfaces of the movable grid seat and the fixed grid seat; the movable grid seat is pressed on the fixed grid seat by a spring so as to keep the movable grid and the fixed grid to be tightly attached; a fixed sleeve is mounted on the threaded sleeve, and a rotating sleeve sleeving the fixed sleeve is mounted at the rear end of the rotating shaft; a graduated scale for reading the moving distance of the rotating sleeve is arranged between the fixed sleeve and the rotating sleeve; and a display for converting angular displacement of the moving gate relative to the fixed gate into linear displacement through data processing and directly displaying data is arranged.
