Steering gear rack vent hole detecting device and detecting method

The invention discloses a steering gear rack vent hole detecting device and detecting method. The detecting device comprises a detecting platform, and supporting blocks for supporting a steering gear rack are arranged on the detecting platform. A detecting plug pin which is inserted into a vent hole to detect the inclination degree of the vent hole is arranged on the detecting platform. A supporting column is arranged on the detecting platform, an adjusting mechanism is arranged on the supporting column to be connected with a dial indicator on the supporting column, and a measuring head of the dial indicator is in contact with the end face where the vent hole in the steering gear rack is formed. According to the detecting method, the vent hole is detected through the steering gear rack vent hole detecting device. The inclination degree and position of the vent hole can be detected. Therefore, the position and inclination degree of the vent hole of the steering gear rack can meet requirements, and the product yield and product consistency of the steering gear rack can be improved. According to the device and method, operation is convenient, detecting accuracy is good, detecting efficiency is high, and good universality is achieved.
