[0002] Brake discs are crucial components in modern automotive braking systems, responsible for converting kinetic energy into heat energy, thereby achieving vehicle deceleration and stopping. During use, brake discs are subjected to varying degrees of friction, and thus the uniformity of their surface and internal thickness directly affects braking effectiveness, brake performance, and safety. Non-uniform thickness of brake discs can lead to unbalanced braking effects, affecting driving safety and potentially causing premature brake disc wear, thermal degradation, and brake judder.

[0003] Traditional brake disc thickness detection methods mostly rely on manual or hand measurement, often using tools such as calipers or micrometers. These methods are not only inefficient, but also require high technical skills from operators and are prone to errors. In addition, traditional manual measurement methods cannot achieve comprehensive and continuous thickness detection of the entire brake disc surface, which may miss local thickness changes, resulting in inaccurate detection results.

[0004] Our company has designed a production line for brake discs. If the detection of the uniformity of the thickness of the brake discs is still detected by manual detection, the production line needs to be temporarily suspended, and then the brake discs are detected, and after the detection is completed, the subsequent operation is performed. This operation not only reduces the production efficiency, but also does not meet the original intention of designing the production line to improve production efficiency, and also has the above-mentioned adverse effects of manual detection. Therefore, it is an urgent requirement to design a device suitable for detecting the thickness on the production line.

Existing automated detection systems mainly use optical, laser, ultrasonic, and other technologies to achieve high-precision and high-efficiency detection of brake disc thickness. These technologies can quickly and non-destructively obtain brake disc thickness data and comprehensively analyze its uniformity, thereby providing more accurate and reliable detection results. For example, laser ranging technology can scan the surface of the brake disc through high-precision laser beams to obtain real-time thickness information of each point on the surface, and then analyze the thickness distribution of the brake disc through data processing technology. In addition, ultrasonic detection technology can analyze the internal structure of the brake disc without contact by transmitting sound waves and analyzing the echo signals, further ensuring the uniformity of the brake disc thickness.

One end of the rolling shaft 230 is conical and finally deformed into a rectangle or a hexagon, and the outer diameter of the rectangle or the hexagon is smaller than the diameter of the main body of the rolling shaft 230.

[0026] When using automatic control, a controller needs to be set, or the sensor, the electric control module and the controller of the pipeline system are connected, so as to realize automatic detection.
