Detection machine for automobile wheel end face run-out error

Abstract

The invention provides a detection machine for an automobile wheel end face run-out error. The detection machine is composed of a driving device, a detecting device, a clamping device and a lathe bed. According to the key of the driving device, a motor and a lead screw and nut pair drive a sliding support to move up and down. The detecting device mainly comprises a measurement head frame, a connecting shaft, a taper sleeve, a locating plate and a plurality of sensor. The upper end of the connecting shaft is fixed to the sliding support of the driving device. The connecting shaft is sleeved with the measurement head frame in a spaced mode. The taper sleeve is fixed to the lower end of the connecting shaft. The taper sleeve is matched with a taper hole formed in the measurement head frame. Under the action of elastic force of an upper spring and a lower spring, the measurement head frame is in the floating state. The locating plate is fixed to the lower end of the measurement head frame and serves as a locating datum. The sensors are evenly fixed to the outer edge of the upper end of the measurement head frame in the circumferential direction. The clamping device clamps and locates an automobile wheel. According to the detection machine for the automobile wheel end face run-out error, one plane is simulated through the multiple sensors, contact measurement is conducted once, the detection period is short, and detection efficiency is high; the floating measurement head frame is adopted, the clamping and locating error of the detected automobile wheel can be eliminated, and therefore the detection precision is improved.

Description

technical field [0001] The invention relates to a detection machine for automobile wheels, in particular to a detection machine for end surface swing of automobile wheels. Background technique [0002] The automobile wheel is an important component of the automobile. Its production quality, especially the swing error of the wheel, has a great influence on the driving safety and comprehensive performance of the automobile. Today's wheel production is getting faster and faster, and the speed of on-line inspection of automobile wheels is getting higher and higher. Most of the current automatic production line inspection equipment for automobile wheels uses a single sensor to rotate a circle to measure the end face swing, which has a long detection cycle and low efficiency. . Contents of the invention [0003] The object of the present invention is to provide a detection machine for the end face swing of automobile wheels, which is used for rapid detection of the end faces of...
