Description
TECHNICAL FIELD
[0001] The utility model mainly relates to the technical field of automobile sleeve spare part detection, and specifically relates to a radial runout measuring tool. BACKGROUND
[0002] Automobile spare parts refer to various units constituting the whole automobile and a kind of product serving the automobile. Automobile spare parts are various in types, and they are important components of the automobile. A car is generally composed of tens of thousands of parts, which can be divided into multiple categories according to their properties, such as engine system, transmission system, braking system, steering system, walking system, electrical system, etc. Automobile spare parts are the foundation of the automobile industry, and their quality and performance directly affect the overall performance and safety of the automobile.
[0003] The sleeve, also known as a bushing, is a common automobile spare part. During the production and processing of the sleeve, the radial runout of the sleeve needs to be detected, as this parameter is directly related to the performance and quality of the sleeve. If the radial runout of the sleeve is too large, it may affect the accuracy and stability of the entire system, thereby affecting the processing quality of the components cooperating with it, leading to a decline in the overall performance of the product. Currently, the radial runout of the sleeve is mainly detected by the three-coordinate method. First, a coordinate system is established on the measuring machine, which usually includes X, Y, and Z axes. Then, a suitable measurement program is written or selected using measurement software, and the measurement path is determined, including the movement trajectory of the measuring head and the measurement points. After starting the measurement program, the measuring head starts moving according to the predetermined path, and the measuring head performs contact or non-contact measurement at each measurement point to record the data. The coordinate data of each measurement point is collected by the measuring machine. For radial runout measurement, the radial size data of the sleeve at different angles is mainly collected. However, this measurement method is slow and time-consuming, and the efficiency is low in the environment of factory batch production. UTILITY MODEL CONTENTS
