Technical Field

[0001] The utility model belongs to the technical field of automobile parts processing, and in particular relates to a tool for deburring screw holes for mounting a rear axle housing of an automobile chassis. Background Art

[0002] The rear axle housing of a car is an important component of the car. It forms a drive axle with the main reducer, differential and wheel transmission device. Its main processing surfaces are the outer circle of the end face, the flange plane, the spring seat plane, and the inner hole. At the same time, screw holes will be processed on it, which will also cause protruding burrs on the inner part of the screw holes.

[0008] A cutting mechanism, arranged at the end of the connecting shaft, for milling burrs on the mounting screw holes of the rear axle housing;

[0009] The adjusting mechanism is installed and arranged between the connecting shaft and the cutting mechanism.

[0010] Preferably, an extension bar is provided at the other end of the connecting shaft, and a milling cutter head is provided at the end of the extension bar.

[0011] Preferably, the installation and adjustment mechanism includes two extension columns fixedly connected to the connecting shaft.

[0012] Preferably, a transverse groove is formed through the interior of the extension strip, and one end of the extension column passes through the transverse groove and extends to the outside of the extension strip.

[0013] Preferably, nuts are threadedly mounted on the outer surfaces of the two extension columns.

[0014] Preferably, the outer surface of the extension column is connected to the transverse groove.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] (1) By setting the cutting mechanism and cooperating with the spindle connection end on the connecting shaft, it can be connected to the spindle of the machining center, thereby driving the cutting mechanism to remove the burrs generated by the screw holes inside the rear axle housing by milling, which is more convenient to use and ensures the effect and degree of burr removal.

[0017] (2) By installing the adjustment mechanism, the extension length of the extension strip can be conveniently controlled to adapt to different rear axle housings. The extension strip and the milling cutter head thereon can also be replaced as a whole, which is more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS
