Abstract

Disclosed is a deburring device for a back cavity of a wheel, composed of a machine frame, a clamping and rotating system, a rising and falling translation system and brush units. Jaws clamp a wheel on a roller way, upper cylinders enable the wheel to rise through four upper guide posts, and a first servo motor enables the wheel to move to upsides of conical sleeves through a second gear rack and a second gear; the upper cylinders enable the wheel to fall, and outer sides of the four jaws are in fit with the conical sleeves; a second motor enables the wheel to rotate in a clamped state; a first motor drives a bottom plate and a brush system to rotate in a circumferential direction through a first synchronizing belt; a second servo motor drives a first brush to rotate, a third servo motor drives a second brush to rotate, and brush hairs of the two brushes apply brushing forces of different directions to a back cavity of the wheel; a direction of rotation of the wheel is opposite to that of the brush system; and lower cylinders enable the brush system to rise through lower guide posts, and the brush system can carry out deburring when the brush system is in contact with the back cavity of the wheel.
