Hole coaxiality detection device of automobile brake system clamp body

Abstract

The invention relates to a hole coaxiality detection device of an automobile brake system clamp body. The hole coaxiality detection device comprises a positioning shaft (1), a detection head (2), a crank arm (3), a transmission shaft (4), a support shaft (5), an adjusting knob (6) and a dial indicator (7), wherein the positioning shaft (1) is completely matched with a detected workpiece datum hole, the detection head (1) is contacted with the inner diameter of the detected hole, the offset of the detection head (2) corresponding to the positioning shaft (1) is transmitted to the dial indicator through the crank arm (3) and the transmission shaft (4) and expressed in a numerical form directly. A maximum value read when a rotating support shaft (5) rotates for a cycle is the offset of the detected hole. The detection device provided by the invention has the characteristics of convenient detection, accurate data, easy operation and the like, has an actual using effect for detection of the hole coaxiality of the automobile brake system clamp body, enables the production and detection efficiency of the automobile brake system clamp body to be greatly improved, and greatly reduces the processing reject ratio of the automobile brake system clamp body.
