The brake shoe support pin is generally made of a pin shaft and a pin plate. It is necessary to ensure that the pin shaft and the pin plate are in a vertical state without tilt deviation. Traditional brake shoe support pins need to be inspected by manual vernier calipers during processing. This manual inspection method often results in inspection errors, resulting in the inability to screen out inferior products. Therefore, a brake shoe support pin detection device is proposed.
