On-line measurement device for shallow-spigot part with shaft in middle

Abstract

The invention discloses an on-line measurement device for a shallow-spigot part with a shaft in the middle. The on-line measurement device comprises a support, a measurement instrument, a fixed frame, a lever, a pin shaft, a tension spring, a slide block, a floating point gauge and a fixed point gauge, wherein the fixed frame is provided with a through hole; the lever penetrates through the through hole and is hinged to the through hole by virtue of the pin shaft; the tension spring is slantwise arranged between the lever and the fixed frame; the measurement instrument is fixedly connected to the fixed frame; a measuring rod of the measurement instrument is in contact with the lever; the support is provided with a lever through hole and a guide sliding chute; the fixed frame is fixedly arranged on the support; the through hole in the fixed frame corresponds to a through hole in the lever in position; the slide block is arranged in the guide sliding chute; the fixed point gauge is arranged on the slide block; the floating point gauge is arranged on the lever; the middle part of the support is provided with a middle hole. The on-line measurement device disclosed by the invention has the advantages of wide measurement range, high detection precision, convenience in operation and low cost; the on-line measurement device for the diameter of the shallow-spigot part with the shaft in the middle appears at home and abroad for the first time.

Description

technical field [0001] The invention relates to a measuring device, more specifically, to an on-line measuring device for shallow seam parts with a shaft in the middle. Background technique [0002] In the processing, assembly and finished product testing of mechanical parts, on-site technical measurement runs through the whole process of various parts and complete machines. The machining accuracy of the parts directly affects the performance and service life of the product. In the current development period of production internationalization and global economic integration, all kinds of products produced in different countries and regions must have high-quality reliability and interchangeability of unified international standards. Therefore, measurement technology and means are the ones who define the production process of various products, from blanks to complete machines, and are the ultimate judges of the quality of these products. [0003] On-line measuring tools are ...
