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, supporting blocks for supporting a steering gear rack are arranged on the detecting platform, and V-shaped grooves are formed in the top ends of the supporting blocks. A detecting plug pin inserted into the 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, a dial indicator connected to the supporting column through an adjusting mechanism is arranged on the supporting column, and a measuring head of the dial indicator is in contact with the end face of the end, where the vent hole in the steering gear rack is formed, of the steering gear rack. 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, so that the position and inclination degree of the vent hole of the steering gear rack meet requirements, and the product percent of pass and product consistency of the steering gear rack are improved. According to the detecting device and detecting method, operation is convenient, detection accuracy is good, detecting efficiency is high, and good universality is good.
