Comprehensive detection device for geometric parameters of conical ring

Abstract

The invention discloses a comprehensive detection device for geometric parameters of a conical ring. The device is applicable to comprehensively detecting various geometric parameters such as the conical degree, the conical height, the large-end (or small-end) diameter and the like of the conical ring (an inner cone), and mainly, functionally and structurally comprises a large movable measuring head, a small movable measuring head, a mandrel, a spring, a linear bearing, a positioning pin, a CCD ((charge coupled device), a displacement sensor and a contact detection sensor. The diameter difference of the two measuring heads is a fixed value, a detected part is movable while a measuring device is fixed in measurement so that measuring efficiency is greatly improved, and by the aid of the linear bearing and the spring, the detected part and the measuring heads can be placed in correct relative positions in measurement, so that measuring errors can be greatly decreased and the measuring efficiency is improved. The three geometric parameters including the conical degree, the conical height and the large-end (or small-end) diameter of the detected part can be detected by means of one-step operation, so that the measuring efficiency is equivalently improved by a few times. Besides, the device is simple in structure and convenient in operation, and the requirement on the technical level of operators is quite low.

Description

technical field [0001] The invention belongs to the technical field of measurement applications, and relates to a detection device, in particular to a comprehensive detection device for geometric parameters of a cone ring. Background technique [0002] At present, the geometric parameters of the cone ring (inner cone) parts in the production site are usually measured by various measuring tools, and only one parameter index can be tested at a time. For example, the height of the cone ring is mainly measured with a vernier caliper, and the taper of the cone ring The plug gauge is mainly used for measurement, and the end diameter of the cone ring (including the diameter of the large and small ends) is sometimes only qualitatively detected, and sometimes it cannot be detected specifically (due to the requirements of the process, there are chamfers at both ends of the cone ring, so it cannot be tested) directly measure the diameter of both ends of the cone).

[0002] At present, the geometric parameters of the cone ring (inner cone) parts in the production site are usually measured by various measuring tools, and only one parameter index can be tested at a time. For example, the height of the cone ring is mainly measured with a vernier caliper, and the taper of the cone ring The plug gauge is mainly used for measurement, and the end diameter of the cone ring (including the diameter of the large and small ends) is sometimes only qualitatively detected, and sometimes it cannot be detected specifically (due to the requirements of the process, there are chamfers at both ends of the cone ring, so it cannot be tested) Directly measure the diameter of both ends of the cone)

At the same time, the use of plug gauges to detect the taper of the cone ring is only a qualitative measurement, and the accuracy is not high and the efficiency is low.

[0003] In short, the comprehensive detection efficiency of the geometric parameters of the existing synchronizer cone ring is low, the overall accuracy is not high, and the technical level of the operator is high, which cannot well meet the actual production site detection needs.
