Detailed Description

The rotary deburring device of the present utility model will be described in more detail below in conjunction with the schematic drawings, in which preferred embodiments of the present utility model are shown, it being understood that the person skilled in the art can modify the utility model described herein while still achieving the advantageous effects of the utility model. Accordingly, the following description is to be construed as broadly known to those skilled in the art and not as limiting the utility model.

The utility model is more particularly described by way of example in the following paragraphs with reference to the drawings. The advantages and features of the present utility model will become more apparent from the following description. It should be noted that the drawings are in a very simplified form and are all to a non-precise scale, merely for convenience and clarity in aiding in the description of embodiments of the utility model.

As shown in fig. 1 and 2, an embodiment of the present utility model proposes a rotary deburring device comprising a sleeve 1, a rotary disc 2 and a grit grinding layer.

The rotary disk 2 is rotatably arranged inside the sleeve 1 and used for driving the coarse sand polishing layer to rotate so as to finish polishing burrs of a workpiece to be polished inside the coarse sand polishing layer.

The coarse sand polishing layer is tiled on the rotary disc 2 and is arranged inside the sleeve 1, and can wrap and hide a piece to be polished so as to rotate along with the rotary disc 2, and burr polishing of the piece to be polished is completed by utilizing the rotation characteristic.

Specifically, the coarse sand polishing layer comprises a plurality of blocks 3 which can be in hard collision and hard contact with a workpiece to be polished, and the burr polishing function is realized by utilizing the collision and friction between the blocks 3 and the burr position of the workpiece to be polished.

This device is through setting up rotary disk 2 and can wrap up the coarse sand layer of polishing of hiding the piece of waiting to polish, utilize rotary disk 2 rotatory time the piece 3 can with wait to polish the piece contact collision and frictional characteristic, come to remove the burr of waiting to polish the marginal position of piece, and because wait to polish the piece and wholly arrange in coarse sand layer of polishing in, so can omnidirectionally polish, can save among the prior art because of the position demand of polishing, and need the time of corresponding adjustment polishing tool position, and then reach the purpose of shortening required duration when rough polishing process.

Specifically, when the rotating disc 2 rotates, the coarse sand polishing layer wraps the workpiece to be polished and rotates together, so that the block 3 collides with the burr part at the edge of the workpiece to be polished irregularly.

In other embodiments, an annular protrusion 4 is added to further enhance the polishing effect. Specifically, the inner wall of the sleeve 1 is provided with an annular protrusion 4 extending to the axial direction of the sleeve 1.

Wherein, annular bulge 4 is arranged above the coarse sand polishing layer, so that the blocks 3 can be gathered at the edge position of annular bulge 4 under the influence of centrifugal force when rotating.

Further, the upper surface of the annular projection 4 is provided in a flat surface, and the cross section of the annular projection 4 is gradually reduced in a direction approaching the axial center of the sleeve 1.

Specifically, the lower surface of the annular protrusion 4 is provided with an arc surface 41, so that when the block 3 is driven by the rotation of the rotating disc 2 to move along the direction away from the axis of the rotating disc 2, the block can be overturned along the arc surface 41 to cover and collide with the workpiece to be polished, thereby improving the burr polishing effect of the workpiece to be polished.

The sleeve 1 and the annular protrusion 4 are integrally formed.
