Abstract

Disclosed is a size-variable wheel deburring device including combined manipulators, a transfer manipulator, a burr brushing system, fixture systems, and so on. Pneumatic fingers grip shanks of retaining pins to bring pin bodies into fit with first retaining sleeves and second retaining sleeves, and retaining lugs with guide grooves. Springs are compressed to cause 90-degree rotation of pin bodies such that retaining lugs come into retaining grooves of the second retaining sleeves. A brush is driven by a driving motor to rotate and elevated by right elevating cylinders to contact with a back cavity of a wheel for deburring. The size-variable wheel deburring device is capable of automatically adjusting the size of the brush and of each fixture according to the diameters of wheels in use, and realizing mixed online burr brushing, and additionally has the characteristics of advanced technique, high automation degree, good universality, and safe and stable performance.
