Problems solved by technology

[0003] At present, most of the measuring tools used to measure the thickness of brake discs are manually measured or special measuring tools such as micrometers and dial gauges are used. Since the brake disc will have a certain slope in the radial direction after long-term use, the accuracy of the above-mentioned measurement poor
In the prior art, there is also detection through special tooling, but the price of the device is relatively high and the adaptability is poor

Abstract

The invention discloses an automobile brake disc flatness detection device, which is characterized in that two groups of measuring screws are symmetrically arranged on two sides of the upper part of abrake disc, the middle parts of the measuring screws penetrate through second threaded sleeves, the second threaded sleeves are in threaded fit with the measuring screws, and rotating sleeves are fixed at the front ends of the measuring screws; the rear portions of the rotating sleeves cover the outer sides of the front portions of the second threaded sleeves, scales are arranged on the outer surfaces of the second threaded sleeves, scale values are arranged on the outer sides of the rotating sleeves, the two sets of second threaded sleeves are symmetrically fixed to the lower end of the fixing frame, and the lower end of a lifting screw is inserted into a bearing which is fixed to the center of the top of the fixing frame. The lifting screw is in threaded fit with the first threaded sleeve, the first threaded sleeve is fixed to the top fixing table, the center positioning column is matched with a center hole of the brake disc, and the first positioning pin and the first fixing bolt penetrate through a fixing bolt hole of the brake disc. The device has the advantages of being high in detection precision, low in cost and high in adaptability.

Description

technical field [0001] The invention belongs to the technical field of automobile maintenance, and in particular relates to an automobile brake disk flatness detection device. Background technique [0002] The brake disc is also called the brake disc, which can directly reflect the quality of the braking effect, so the brake disc is the most critical and direct component in the car braking system. Generally, the brake disc has a disc-shaped structure, and the production material is mostly gray cast iron containing low chromium. There are many performance indicators to measure the brake disc (such as flatness, eccentricity, parallelism, balance, etc.), among which the surface roughness of the brake disc is the most important performance indicator. Therefore, whether it is before the new brake disc is manufactured or the old brake disc is worn out after a period of use, it is necessary to carry out the corresponding surface roughness test to determine whether the newly produc...
