Problems solved by technology

[0002] In the background technology, the current online measurement of the height of the conical surface of the conical part generally adopts the measurement method of the sample column and the sample ring. Such a measurement method can generally only be used for dimensional inspection with a height tolerance greater than 0.3mm. The accuracy is low, the versatility is poor, and the measurement process is complicated. It is becoming more and more difficult to meet the rapid measurement requirements of high-precision conical parts.

Abstract

The invention relates to a cone height measuring device. The main technical characteristic is that the cone height measuring device comprises a dial indicator display, an elastic bush, a knurled screw, a positioning sleeve, a screw plug, a pressure spring, a main body, a measuring bar, a locking screw, a standard body, a handle, a positioning plate and a fastening screw, wherein the dial indicator display is inserted into the elastic bush; the measuring head of the dial indicator display is fit with the tail end part of the measuring bar; and the head part of the measuring bar adopts a cylindrical and short cone surface structure. The cone height measuring device adopts a comparative measurement method which comprises the following steps: calibrating the dial indicator display by using the standard body into a zero position; and measuring the cone surface of a tested cone-shaped part, wherein the dial indicator display displays an error reading value deviate from the zero position, and the sum of the height of the standard cone surface of the standard body and the error reading value deviate from the zero position is the height of the cone surface of the tested cone part. The cone height measuring device has the characteristics of simple and compact structure, high generality, convenience and quickness in measurement, low manufacturing and using cost and the like.

Description

technical field [0001] The invention relates to a cone height measuring device, which belongs to the technical field of process equipment, and is especially suitable for measuring the height of cone surfaces of various sizes of cone parts. Background technique [0002] In the background technology, the current online measurement of the height of the conical surface of the conical part generally adopts the measurement method of the sample column and the sample ring. Such a measurement method can generally only be used for dimensional inspection with a height tolerance greater than 0.3mm. The accuracy is low, the versatility is poor, and the measurement process is complicated. It is becoming more and more difficult to meet the rapid measurement requirements of high-precision conical parts. In order to overcome the deficiencies of the existing technology and meet the needs of modern production, a conical height measuring device was studied. Contents of the invention [0003]...
