In the casting process of the metal part of the existing deburring technology, for the same type of workpiece, burrs generated at the same position of different individuals are different in length, and when the burrs on one workpiece are removed and the burrs on the other workpiece are removed by the same cutting force, if the cutting force is too small, incomplete removal is possible; if the cutting force is too great, secondary burrs and even workpiece rejection may result. And for the burrs of the casting contour and the protrusions and burrs around the parting surface of the casting, if the burrs are removed by a rigid cutter, the difference of chamfer appearance of the part for removing the burrs is larger because of the difference of blank allowance and position. Accordingly, the present application discloses a deburring tool holder that floats angularly and axially upward.

6. Cutting portion

The collet 13 is fitted into the bottom tapered hole of the second movable shaft 11, and the cutting bit 32 is fitted into the collet 13 and tightened by the nut 12. At this time, the installation is completed.

Before machining, the cutting edge of the rotary file is adjusted to apply proper over-cutting amount to the edge of the workpiece. In the machining process, pressure is continuously increased for the rotary file through the spring, so that the cutting edge of the rotary file can be attached to the edge of a workpiece to remove burrs, and the chamfering is basically uniform. While also compensating for errors between programming and actual workpieces.

Before machining, the cutting edge of the cutting tool bit 32 is adjusted to apply proper pre-pressing amount to the edge of the contour of the workpiece, during machining, the tool shank carries out deburring work along the contour of the side face of the workpiece, the cutting tool bit 32 swings at an angle and axially moves upwards when meeting an uneven contour or a curved contour, the first movable shaft 20 and the second movable shaft 11 respectively move to compress the second spring 9 and the first spring 10, the force of the springs is utilized to cut the tool bit 32 to carry out deburring work on the workpiece, and when the tool shank moves to the reverse direction, the two springs gradually reset the first movable shaft 20 and the second movable shaft 11, so that the cutting tool bit 32 is gradually reset.

The larger the burr of the workpiece profile, the more the cutting bit 32 deflects, the more the spring is compressed and the more the force of the spring is, so that stable deburring is possible.

In the idle state, the axis of the first movable shaft 20 is concentric with the axis of the tool shank 24. When in machining and cutting, the first movable shaft 20 is stressed and deflects 5 degrees in the 360-degree direction of the circumference of the cutter handle 24, and the second spring 9 always acts on the large end face of the first movable shaft 20, so that the cutting tool bit can deflect at an angle;

when the cutting bit 32 is subjected to an axially upward force, the second movable shaft 11 moves upward with the cutting bit 32, and the first spring 10 always acts on the second movable shaft 11, ensuring that the cutting bit can be moved axially up and down.

The two springs are combined to enable the cutting tool bit to always fit the contour of the workpiece in the angle and axial directions, and copying machining of the contour of the workpiece is achieved. The second spring 9 and the first spring 10 may be selected to be suitable depending on different workpieces.
