A kind of conicity measuring device and method for inner cone

Abstract

The invention discloses a device and method for measuring the conicity of an inner cone. The device comprises a line laser device for emitting line lasers to the surface of the inner cone, a laser graph is formed by the line lasers on the surface of the inner cone, obtained by an image sensor, and transmitted to a central processing unit, and image processing is carried out according to the chord length formula and the conicity formula. The device and method are characterized in that the measuring method is achieved through machine visions, the inner conicity of a workpiece to be measured can be rapidly measured, the detection efficiency and the detection accuracy can be improved, and rapid complete detection on measured elements which can be originally and casually detected can be carried out. The aims of replacing a solid test tool, improving the product quality, reducing the labor strength and improving the customer satisfaction are achieved.

Description

technical field [0001] The invention relates to a conicity measuring device and method for an inner cone, belonging to the field of measuring devices. Background technique [0002] At present, the development of the manufacturing industry is changing with each passing day, which puts forward higher requirements for the quality of parts manufacturers, especially the critical dimensions, which need to be fully inspected to ensure the reliability of the product. The usual method is to use physical inspection tools or inspection tools. Manual full inspection of the equipment is usually very time-consuming, and due to the operation of different employees will cause large operational errors, the accuracy and speed of the inspection cannot be guaranteed. Contents of the invention [0003] Purpose of the invention: The present invention proposes a conicity measurement device and method for internal cones, which can quickly measure the internal conicity of the workpiece to be teste...
