AI Technical Summary

Technical Problem

The existing shaft-type parts measuring devices cannot automatically judge the accuracy of the measurement results during measurement, and the operation is cumbersome, requiring the gear to be toggled multiple times, and the detection time is slow.

Method used

A measuring device including the device base, threaded block, main body, rubber block, base plate, linkage block, spring and measuring block is designed. Through the automatic limit and spring return structure, the parts are automatically fixed in the center when entering the device, and the base plate is automatically squeezed. Pressure measurement block, staff can judge the outer diameter based on the measurement block to ensure the accuracy of the detection results.

Benefits of technology

It realizes automatic centering and fixing of parts and accuracy of measurement results, improves detection efficiency, simplifies operational processes, and reduces detection time.

Abstract

The utility model discloses an outer diameter measuring device for shaft part processing, which relates to the technical field of measurement and comprises a device base, a threaded block connected above the device base, a device main body connected above the threaded block, a storage groove arranged at the center of the device main body, and a rubber block connected at the bottom of the device main body. A bottom plate is arranged in the device body, a linkage block is connected in the bottom plate, a second spring is connected in the linkage block, a cross rod is connected to the center of the linkage block, a measuring block is arranged on the surface of the cross rod, and a connecting block is connected to the upper portion of the bottom plate. When the base plate moves, the base plate drives the linkage block and the cross rod on the outer side of the base plate, so that the measuring blocks stretch out towards the outer side of the device body, then a worker can measure the radius from the center of a part to the outer side surface according to the scales of the measuring blocks, and meanwhile whether the size is correct or not can be judged according to the three different measuring blocks.
