Soft object measuring device for preventing extrusion damage by using light outage

Abstract

The invention relates to the technical field of size measurement, and provides a soft object measuring device for preventing extrusion damage by using light outage. The device comprises a machine body, a threaded rod is movably connected with the inner wall of the machine body, a threaded sleeve is movably connected with the outer wall of the threaded rod, and a support frame is fixedly connectedwith the outer wall of the threaded sleeve. According to the soft object measuring device for preventing extrusion damage by using light outage, the support frame drives a connecting rod to get closeto a soft object, the connecting rod and a base plate slowly move to get close to the soft object, and when the base plate makes contact with the soft object, a photoresistor in the base plate cannotmake contact with the light, and the resistance value is increased; when the resistance value of the photoresistor is increased, a clamping block limits movement of the connecting rod, all the photoresistors are not irradiated by light, a driving mechanism stops, the size of a size meter plate on the outer wall of a lever blocked by a blocking block is the average value of the thickness of the soft object, and errors caused by deformation of the soft object are prevented by measuring the thickness through light blocking outage.

Description

technical field [0001] The invention relates to the technical field of size measurement, in particular to a soft object measuring device that prevents extrusion damage by using light to cut off power. Background technique [0002] Thickness measurement refers to the measurement of the thickness of an object. Thickness measurement was initially measured by a scale, and later gradually developed into a micrometer and a semiconductor laser. The measured data is becoming more and more accurate. With the development of the times, industrial automation has become an inevitable development. The main factor affecting it is the control process to detect equipment, and the dimensional accuracy directly affects the quality of the product. [0003] In the prior art, the ruler used to measure the thickness needs to be manually measured and subjectivity factors are greatly affected, while the semiconductor laser will cause certain damage to the object, the soft object is very fragile and ...
