Device for burring front face of wheel

Abstract

The present invention relates to a device for burring a front face of a wheel. The device is composed of a rack, a motor, a guide rail, air cylinders, brushes and the like. A sensor enables the wheel to be positioned on a roller way, a clamping air cylinder drives left rolls and right rolls via synchronous gears and gear racks to clamp the wheel, a servo motor drives the wheel to rotate at relatively low speed under the clamped condition, and the rotation direction of the wheel is opposite to that of the brushes; the air cylinders I enable a dust cover to go down, and the motor drives a gear I and a central brush via a shaft II to rotate at relatively high speed; the gear I drives a gear II and a gear III to rotate simultaneously at slightly slow speed, so as to drive an outer ring brush to also rotate at relatively slow speed; and the air cylinders II drive the central brush and outer ring brush to go down, and burring can be performed once the central brush and outer ring brush contact the front face of the wheel. When in use, the device provided by the present invention can burr the central part and the spoke of the wheel at different rotation speeds, and the problem that the traditional big disc brush has low linear speed at the central position when rotating at fixed angular speed is avoided.

The upper end of the III shaft 27 is also fixed under the inner ring of the swivel 15. The gear I 11 is simultaneously engaged with the gear II 13 and the gear III 26, and the gear II 13 and the gear III 26 are also simultaneously engaged with the gear ring 14. The central brush 9 is placed at the center of the outer ring brush 10, and forms a certain gap with the same. The shaft II 19 is fixed in the lower bearing block 22 under the lifting plate 20 via a bearing, and the upper end of the shaft II 19 is connected with the motor 23 fixed on the lifting plate 20.
