Special equipment for deburring of hub valve hole

Abstract

The invention discloses special equipment for deburring of a hub valve hole. The special equipment can effectively improve deburring efficiency, reduce labor intensity and guarantee stable deburring quality. The special equipment comprises a machine table, an annular lower die table and a punch, wherein the annular lower die table is arranged on the machine table and matched with the inner peripheral face of a hub, and the punch is located above the annular lower die table. The outer peripheral face of the annular flow die table is provided with a vertical hole corresponding to the hub valve hole, and the included angle between the center line of the vertical hole and the center line of the annular lower die table is the same as that between the axis of the hub and the center line of the valve hole. An alignment ejector pin capable of moving upward and downward and a first reset spring located below the alignment ejector pin and used for ejecting the alignment ejector pin are disposed in the vertical hole. The punch is located over the alignment ejector pin.

Description

technical field [0001] The invention relates to a deburring device, in particular to a special device for deburring a hub valve hole. Background technique [0002] During the manufacturing process of the automobile wheel hub, a valve hole needs to be punched out on the rim of the wheel hub. The blanking process inevitably produces burrs on the edge of the valve hole; therefore, a deburring process is required after the valve hole is punched and formed. At present, the deburring process of the valve hole of the wheel hub usually uses an electric drill or a manual drill; when deburring, the operator holds the drill and adopts the method of manually drilling the burr with the drill to remove the burrs on the edge of the valve hole. For example, Chinese Patent Publication No. CN1843675, date of publication on October 11, 2006, is a quick manual cleaning tool for orifice burrs, in which there is a bowed crank with a rotatable crank short pipe in the middle, and the top of the cra...
