Accurate equipment for detecting tubular automobile part by utilizing light reflection principle

Abstract

The invention relates to the technical field of automobile parts, and discloses accurate equipment for detecting a tubular automobile part by using a light reflection principle. The top end of a main body is movably connected with a center block, and the left and right sides of the center block are movably connected with protective strips. According to the precise equipment for detecting the tubular automobile part by using the light reflection principle, a main shaft penetrates through the center block to synchronously move downwards, the center block is provided with textures matched with the main shaft, the main shaft drives a rolling roller movably connected with the axis to synchronously move, and a detection ball at the bottom end of a circumferential rod rotates along with the rolling roller to synchronously move; the circumferential rod is extruded by the rolling roller to perform upward extrusion operation, and through cooperative use of the circumferential rod, a frame, the center block, a metal piece and the auxiliary strip, the equipment has the function of synchronously performing roundness detection and flatness detection, so that the effects of reducing the detection steps and shortening the detection time are achieved, and meanwhile, the detection accuracy is also ensured.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a precision device for detecting tubular auto parts by using the principle of light reflection. Background technique [0002] Auto parts are the various units that constitute the whole car and a product that serves the car. There are many types of auto parts. With the improvement of people's living standards, people consume more and more cars. The market for auto parts has become It is also getting bigger and bigger. Auto parts mainly include engine assemblies, filters, cylinders and components, oil seals, oil pump nozzles, fuel economizers, etc., and the roundness detection of these tube fittings is very important. In recent years, auto parts Manufacturing plants are also growing rapidly. [0003] However, in the traditional tube-type auto parts testing equipment, it is often used to extend the detection parts into the inside of the tube-type auto parts, and then use the ref...

Problems solved by technology

[0003] However, in the traditional tube-type auto parts testing equipment, it is often used to extend the detection parts into the inside of the tube-type auto parts, and then use the reflection of light to detect the roundness, while the traditional method is to erect the tube-type parts , and then detect the flatness of its cross-section, but the two cannot be detected simultaneously, resulting in increased detection steps, slowed down the detection time, cannot guarantee the accuracy of the detection, and delay the work efficiency. In addition, during the detection It is impossible to mark the existing detection problems, which leads to the unknown location of the detection problems in the subsequent processing, and increases the steps of finding the location of the problems, which affects the subsequent processing. Therefore, a method of detecting tubular auto parts using the principle of light reflection Precision equipment came into being
