Description
Technical Field
The utility model relates to a calliper detects technical field, concretely relates to brake caliper's leakproofness detects frock.
Background
The braking performance of the automobile directly influences the driving safety of the automobile. Along with the continuous improvement of vehicle performance, the speed of a motor vehicle is continuously promoted, and people have higher and higher requirements on safety and reliability. In order to ensure the safety of human bodies and vehicles, the automobiles must be provided with a very reliable brake system. In recent years, the use of automobiles in europe and China shows that disc brakes can ensure braking safety, stability, and durability more than drum brakes. The brake caliper is an important component of the disc brake, and the poor sealing performance of the brake caliper can cause the leakage phenomenon of an automobile disc brake assembly, so that the braking force is reduced, and the braking effect is reduced. Serious traffic accidents may occur. Therefore, the detection of the tightness of the brake caliper is very valuable and practical to use. The traditional bubble method and smearing method are backward in detection. The bubble method is simple to operate, the leakage position and the leakage condition can be directly observed, but the bubble method has many defects, if the leakage position and the leakage positions of the workpiece are not known in advance, the full bubbles are difficult to collect, and the accuracy of measurement is influenced; secondly, for parts with large volume and heavy weight, the observation in water is difficult; for parts with complex surfaces, bubbles attach to the bottom and folds of the part and are not easy to observe. The smearing method has disadvantages such as only being able to roughly observe the leakage amount, and being unable to quantitatively measure the leakage amount. The pressure drop method, the flow measurement method and the like have low detection precision, while the helium leakage detection method has high cost, and the methods cannot be suitable for large-scale detection of the brake calipers.
