Deflashing device for wheel blank

Abstract

The invention discloses a deflashing device for a wheel blank, which comprises a machine frame, a servomotor, a synchronous belt, a chuck, a grinding wheel, a lead screw, a guide rail and the like, wherein a clamp is fixed on the chuck; the lower part of the chuck is fixed on the machine frame through a shaft and a bearing support; the chuck rotates under the action of a motor fixed at the left lower part of the machine frame and the synchronous belt; the grinding wheel is fixed at one end of a cross plate of a lifting bracket, and rotates under the driving of a motor fixed at the other end of the cross plate and the synchronous belt under the motor; the lifting bracket is connected with a translational bracket through the guide rail, and drives the lead screw to rotate through a motor, so that the lifting bracket fixed together with a lead screw nut moves up and down; the translational bracket is fixed on the machine frame through the guide rail; and a servo electric cylinder fixed on the right side of the machine frame drives the translational bracket to move horizontally. When any one of two photoelectric switches detects a signal of flashing, the chuck stops rotating, and the grinding wheel cuts the flashing.

Description

technical field [0001] The invention relates to a device for deflashing, in particular to a device for deflashing a wheel blank. Background technique [0002] In the casting process of aluminum alloy wheels, due to the certain gaps in the fittings of each side mold of the mold, the molten aluminum will seep out under the action of pressure, and flashes of a certain thickness and length will be formed at the fittings of each side mold. As the mold is worn during use, the formed flash will become larger and larger; large flash not only affects the positioning accuracy of subsequent machining, but also is very unfavorable to the tool during cutting and increases the cost. The traditional method is to chop off the wheel with a machete when the wheel is just demolded. This method is not only inefficient, but also labor-intensive and the roots are not removed cleanly, which can easily cause damage to the rim and increase the scrap rate.
