Problems solved by technology

This system structure is for batch measurement of a single shaft workpiece. Because the microscope and camera will heat up during operation, it cannot work continuously for a long time. At the same time, for large-volume or complex shaft workpieces, There is no way for this measuring instrument to measure
[0003] Chinese patent 201420164702.9 discloses a comprehensive experimental measurement device for outer diameter, taper and inclination angle. Heat, the measured part is fixed on the adjustment seat relative to the system, so that the system cannot work for a long time, and intermittent work is required
Eventually, the measurement accuracy will decrease, and the machine will have to be shut down for heat dissipation

Abstract

The invention relates to a measuring device. The measuring device comprises an image acquisition mechanism, a load adjusting mechanism, a lighting mechanism and a supporting bottom plate, and is characterized in that the load adjusting mechanism is located between the image acquisition mechanism and the lighting mechanism, the image collecting mechanism comprises a supporting seat, a lens, a camera and a camera radiator; according to the invention, the camera radiator is adopted, so that the camera can work continuously for a long time, the service life of the camera is prolonged, and the measuring accuracy is ensured; an adjusting mechanism which can finely adjust the position of a shaft workpiece to be measured is adopted, so that alignment and high-quality measuring accuracy can be guaranteed; according to the invention, the measuring device has high measuring accuracy, long service life and low cost.

Description

technical field [0001] The invention relates to a measuring device, in particular to a device for measuring the outer diameter of shaft workpieces. Background technique [0002] Chinese patent 201120531421.9 discloses a under-illuminated image measuring instrument for the outer diameter of shaft workpieces. The measuring instrument uses under-illuminated image measurement, that is, the light source is on the underside of the workpiece to be measured, and the workpiece is mounted on a fixed shaft-type workpiece mounting seat. After being illuminated, it is photographed by a microscope and a camera, and the photographed data is processed by a computer, so as to realize the measurement of the outer diameter of the shaft workpiece. This system structure is for batch measurement of a single shaft workpiece. Because the microscope and camera will heat up during operation, it cannot work continuously for a long time. At the same time, for large-volume or complex shaft workpieces, ...
