Description

Technical Field

[0001] The utility model belongs to the field of detectors and relates to a caliper oil pipe clamp hole detection device with an error-proofing function. Background Art

[0002] In the production process, the brake caliper oil pipe clamp hole is the key hole for the caliper body oil pipe assembly, and its accuracy has a vital impact on the assembly of the whole vehicle. If the direction of the oil pipe clamp hole is processed incorrectly or missed during the machining stage, this will become a potential serious problem. If the operators on the assembly site fail to find these wrong parts in time, they will flow into the customer's assembly process, which will not only seriously hinder the assembly progress of the whole vehicle, but may also cause the stagnation and suspension of the production line, resulting in immeasurable losses.

[0003] Traditional detection methods, such as photographic detection, can detect problems to a certain extent, but the high cost and potential abnormal alarm conditions limit its application effect, and there are also abnormal alarm conditions. Therefore, we must pay attention to the machining accuracy and detection quality of the brake caliper oil pipe clamp hole to ensure that each part can be accurately put into the assembly process.
