Description

Technical Field

[0001] This utility model relates to the field of polishing disc technology, specifically to an active polishing disc surface shape control device. Background Technology

[0002] A polishing disc is a key component mounted on polishing equipment, used to contact the workpiece and achieve surface grinding, finishing, and smoothing. Its main function is to physically remove imperfections from the workpiece surface through rotational motion in conjunction with abrasive particles, thereby achieving the set surface finish and shape accuracy.

[0003] Most existing polishing pads are rigid, one-piece designs with a fixed structure. This makes them unsuitable for adjusting to different wear patterns in different areas, easily leading to unevenness and reduced machining accuracy during polishing, severely impacting product quality and production efficiency. Especially when polishing workpieces with complex shapes or varied surface features, traditional polishing pads lack flexible fine-tuning capabilities and cannot quickly respond to and adjust based on actual processing feedback.

[0004] Therefore, it is necessary to design an active polishing disc shape control device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an active polishing disc surface shape control device to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an active polishing disc surface shape control device, comprising a polishing disc, a protective sleeve fitted on the top of the polishing disc, a retaining ring fixedly connected to the top of the protective sleeve, a central column fixedly connected to the bottom of the polishing disc, and a top plate fixedly connected to the top of the central column. A fixing sleeve is fixedly connected to the outer surface of the top plate, and a slot is provided at the bottom of the fixing sleeve. The retaining ring is slidably inserted into the interior of the slot, and a cable tie is movably fitted onto the outer surface of the retaining ring. The retaining ring is then connected to the inner cavity of the top plate via the cable tie. On the side, the top of the polishing plate is provided with a plurality of equally spaced, circumferentially distributed insert rings, and the top of the insert rings is threaded with a plurality of bolts, and the top of the insert rings is threaded with two connecting rings through the plurality of bolts. The top of each of the two connecting rings is fixedly connected with a first connecting post, and the top of each of the two first connecting posts is fixedly connected with a limiting piece. The outer surface of the insert rings is threaded with a screw, and the top of the screw is rotatably inserted into the outer surface of the top plate through a bearing, and the top of the screw is fixedly connected with a knob. The top of the top plate is fixedly connected with a second connecting post.

[0007] Preferably, the number of the insert rings is eight, and the bottom of each of the eight insert rings is in contact with the top of the polishing sheet.

[0008] Preferably, one end of each of the eight insertion rings is provided with an arc-shaped surface, and each of the eight arc-shaped surfaces is in contact with the outer surface of the central column.

[0009] Preferably, an annular notch is provided on one outer surface of the fixing sleeve, and the cable tie is movably sleeved on the outer surface of the annular notch, and the inside of the cable tie fits against the outer surface of the insertion ring.

[0010] Preferably, two of the first connecting posts on each of the plurality of insert rings are slidably disposed on both sides of the screw, and a gap is provided between the bottom of the two limiting pieces and the top of the top plate.

[0012] The technical solution provided by this utility model has the following advantages compared with the prior art:

[0013] This invention achieves regional fine-tuning of the polishing disc surface by incorporating multiple independently adjustable insert ring assemblies on the polishing disc, combined with a knob drive, limit plate constraint, and cable tie connection. When an uneven polishing area occurs, the user can precisely control the raising and lowering height of the insert rings by rotating the corresponding knob, thereby effectively restoring the flatness of that area. The device is compact, easy to operate, and highly precise in adjustment, significantly improving polishing uniformity and processing quality, and extending the device's service life.
