Detailed Description

Example 1

Referring to fig. 1-4, in the present embodiment, a part polishing device includes a barrel 10 and a polishing plate 20, wherein the barrel 10 is disposed at an end of a rotating rod 30, a supporting rod 11 is coaxially disposed in a cavity of the barrel 10, and clamping grooves 12 uniformly distributed along a circumferential direction are disposed on the barrel 11; the polishing plate 20 is slidably clamped in the clamping groove 12 along the radial direction of the barrel 10, a supporting plate 21 abutting against the supporting rod 11 is arranged at the inner end of the polishing plate 20, and a spring 23 is compressed between the supporting plate 21 and the inner wall of the barrel 10.

According to the embodiment, the conventional polishing head is optimized and improved, the barrel part 10 is additionally arranged, the polishing plate 20 matched with the design can synchronously rotate along with the rotating rod 30, the barrel part 10 is limited by the spring 23, and the polishing plate can slide out of the barrel part 10 along the radial direction under the action of centrifugal force, so that the polishing head can be suitable for burr polishing work of parts with different inner diameters, and has the advantage of simplicity and convenience in operation.

In this embodiment, optionally, the left end portion of the barrel 10 is provided with a connecting rod 13 screwed with the rotating rod 30, and the barrel 10 can be conveniently disassembled and assembled on the rotating rod 30 through the threaded connection of the connecting rod 13 and the rotating rod 30, and the rotating rod 30 is connected to the driving mechanism 31 and is driven to rotate by the driving mechanism 31, so as to drive the barrel 10 to rotate synchronously.

Further, in order to secure the smoothness of rotation of the barrel 10, the connecting rod 13 is kept coaxially arranged with the barrel 10.

In addition, an end cover 14 is screwed to the right end of the support rod 11, the end cover 14 is abutted against the right end of the barrel 10, the outer diameter of the end cover 14 is equal to the outer diameter of the barrel 10, so that the inner cavity of the barrel 10 is closed, and the clamping groove 12 extends to the end cover 14 along the axial direction of the barrel 10 as a whole, namely, the clamping groove 12 penetrates through the right end surface of the barrel 10, so that the polishing plate 20 is convenient to assemble and disassemble.

In this embodiment, alternatively, the polishing plates 20 and the clamping groove 12 have the same axial length, the polishing plates 20 are arranged along the radial direction of the barrel 10 as a whole, and the polishing plates 20 are uniformly distributed along the circumferential direction of the barrel 10, and the axial positions of the polishing plates 20 can be limited by the end cover 14, and the polishing plates 20 can be limited inside the barrel 10.

In addition, the support plate 21 is integrally constructed in an arc plate shape attached to the support rod 11, the support plate 21 integrally extends in the axial direction of the support rod 11, the support plate 21 and the polishing plate 20 are integrally formed, the radian of the support plate 21 on both sides of the polishing plate 20 is identical, positioning holes 22 for placing the springs 23 are provided on the support plate 21, and the springs 23 are symmetrically arranged on both sides of the support plate 20.

The spring 23 generates elastic thrust to the support plate 21, and when the barrel 10 is not rotated, the top of the polishing plate 20 is retracted into the barrel 10; when polishing operation is performed, the rotation of the barrel 10 drives the polishing plate 20 to synchronously rotate, and under the action of centrifugal force, the top of the polishing plate 20 extends out to the outer wall of the barrel 10, so that burrs on the inner peripheral surface of the part are polished.

It should be understood that, compared with the conventional polishing head, the polishing device of the present embodiment keeps the position of the rotating rod 30 inside the part unchanged during operation, and does not need to rotate the rotating rod 30 along the inner peripheral surface of the part, which has the advantage of simple operation.
