Description
Technical Field
The invention relates to the technical field of brake disc machining, in particular to a brake disc roundness detection device.
Background
The brake disc, in short, is a circular disc which also rotates when the vehicle is moving. The brake caliper clamps the brake disc to generate braking force, and when the brake is stepped, the brake caliper clamps the brake disc to play a role in reducing speed or stopping. The brake disc has good braking effect and is easier to maintain than a drum brake.
There are many performance indexes (such as flatness, roundness, eccentricity, etc.) for measuring a brake disc, where the roundness of the circumferential surface of the brake disc is a performance index that cannot be ignored after the brake disc is formed, and the performance index directly affects the balance of the brake disc. Therefore, before a new brake disc is manufactured and shipped, roundness detection needs to be performed on the circumferential surface of the new brake disc so as to respectively determine whether the newly manufactured brake disc is qualified or not and can be shipped. The invention discloses a brake disc size detection device, which can refer to a Chinese patent with an authorization publication number of CN114543721B at present, and mainly relates to the field of size detection. Including conveying mechanism, manipulator, testing platform and well control machine, the conveying mechanism end sets up positioner, the manipulator sets up between conveying mechanism and testing platform, the testing platform top surface is rotated and is set up electric chuck, it sets up the detection ring to rotate on the testing platform in the electric chuck outside, detect ring and electric chuck disalignment, it sets up elevating system to detect the ring bottom, can dismantle on the detection ring and set up thickness detection head, plane degree detection head and circularity detection head.
The conventional brake disc roundness detection device basically adopts the same mode as that in the background technology, namely a background comparison system and a front-end detection element are arranged, an error value is preset in the background comparison system in advance, then the roundness of a brake disc is detected by the front-end detection element, a detection result is transmitted to the background comparison system, the detection result is continuously compared with the preset error value through the background comparison system, when the comparison result conforms to the error value range, the brake disc is qualified, and when the comparison result does not conform to the error value range, the brake disc is unqualified, however, the detection device has the advantages that the cost is relatively high because the front-end detection element and the background comparison system are matched for use, a special position is required to be arranged in a workshop for placing the background comparison system, the occupied space is large, and the detection device is more suitable for large-batch brake disc detection; when only need carry out the measuring of small batch brake disc circularity, adopt foretell brake disc circularity detection device, the cost will be higher relatively, and if adopt traditional measurement personnel to detect the back through detection instrument such as micrometer to the brake disc, when the analysis data is compared in the artificial observation, will have complex operation again, and the precision easily receives the artificial influence of operating personnel and leads to the condition of deviation and inefficiency. In summary, it is urgently needed to provide a roundness detection device which has relatively low cost, is suitable for small-batch brake discs, does not need the participation of a background comparison system, does not need detection personnel to compare and analyze data, and can simply, quickly and intuitively judge whether the roundness of the brake disc is qualified.
