Description

Technical Field

[0001] This utility model relates to the field of polishing and finishing technology, and in particular to a polishing pad finishing device. Background Technology

[0002] Polishing pads, also known as polishing sheets, polishing cloths, or polishing discs, are important auxiliary materials in chemical mechanical polishing that determine surface quality. During the polishing process, because the surfaces of the workpieces have tiny bumps and depressions of varying sizes, it is impossible to achieve a completely flat surface. Therefore, the polishing pads need to be adjusted during the polishing process to achieve the best polishing effect.

[0003] In existing polishing pad modification, polishing pads are generally flat. However, when dealing with some workpieces with small and dense uneven surfaces (such as water ripple glass, special surface glass, etc.), it is necessary to modify the polishing pad into a shape with varying thickness. This modification is very troublesome and difficult, and can only be done manually. However, manual polishing is not only inefficient and inaccurate, but also produces poor polishing results. Utility Model Content

[0004] This utility model provides a polishing pad adjustment device. The polishing pad is fixed on the polishing disc, and the adjusting rod is turned to make the bottom head lift up the polishing pad and deform it. The polishing surface of the polishing pad becomes an irregular surface, so that the surface of the workpiece can be polished to different depths. It is especially suitable for processing some workpieces with small and dense concave and convex surfaces. The structure is simple, the polishing precision is high, the effect is good, the efficiency is high, and the applicability of the device is also improved.

[0005] To achieve the above objectives, a polishing pad dressing device is provided, comprising: a polishing disc, a fixed shaft fixedly connected to the top of the polishing disc, a bottom groove and a slide rail provided at the bottom of the polishing disc, two slide rails symmetrically located on the left and right sides of the bottom groove, a limit block fixedly connected to the circumferential surface of the polishing disc, a top groove provided at the top of the polishing disc, and an adjustment component provided inside the bottom groove;

[0006] The adjustment assembly includes a moving block, a slider, an upper adjustment hole, a lower adjustment hole, a top head, an adjustment rod, a fastening bolt, a butterfly knob, and an electric rod. The slider is fixedly connected to the left and right side walls of the moving block. The upper adjustment hole is provided at the top of the moving block, and the lower adjustment hole is provided at the bottom of the moving block. The top head is provided inside the lower adjustment hole, and the top of the top head is fixedly connected to the adjustment rod. The fastening bolt is threaded onto the circumferential surface of the adjustment rod, and the butterfly knob is fixedly connected to the top of the adjustment rod. The electric rod is fixedly connected to the rear side wall of the moving block, and the rear fixed end of the electric rod is fixedly connected to the polishing disc.

[0007] According to the polishing pad dressing device, the electric rod is located inside the bottom groove.

[0008] According to the polishing pad trimming device, there are two limiting blocks, both of which are fixedly connected to the circumferential surface of the polishing disc.

[0009] According to the polishing pad dressing device, the lower adjustment hole is hemispherical and the top head is spherical.

[0010] According to the polishing pad dressing device, the adjusting rod is located inside the upper adjusting hole and is threadedly connected to the polishing disc, and the fastening bolt is located above the polishing disc.

[0011] According to the polishing pad dressing device, a scale is provided on the circumferential surface of the adjusting rod.

[0012] The beneficial effects of this utility model are as follows: By setting a polishing disc, bottom groove, top groove, moving block, slider, upper adjustment hole, lower adjustment hole, top head, adjusting rod, fastening bolt, butterfly knob and electric rod, the polishing pad is fixed on the polishing disc. Turning the adjusting rod causes the bottom head to lift the polishing pad and deform it, so that the polishing surface of the polishing pad becomes an irregular surface. Thus, the surface of the workpiece can be polished to different depths. It is especially suitable for processing some workpieces with small and dense concave and convex surfaces. The structure is simple, the polishing precision is high, the effect is good, the efficiency is high, and the applicability of the device is also improved.

The upper adjustment hole 603 is provided at the top of the movable block 601, and the lower adjustment hole 604 is provided at the bottom of the movable block 601. The top head 605 is located inside the lower adjustment hole 604. The lower adjustment hole 604 is hemispherical, and the top head 605 is spherical. The adjustment rod 606 is fixedly connected to the top of the top head 605. A scale is provided on the circumferential surface of the adjustment rod 606. By controlling the lower adjustment rod 606... The displacement is used to control the deformation of the top head 605 on the polishing pad, thereby controlling the polishing accuracy.

[0027] Working principle: The polishing pad is fixed to the bottom of the polishing disc 1. The polishing disc 1 is fixedly connected to the polishing machine through the fixing shaft 2. By turning the adjusting rod 606 downward, the top head 605 below the adjusting rod 606 moves down and presses the polishing pad. Generally, the polishing pad has a certain degree of elasticity and is made of loose and porous material, so it has a certain degree of extensibility. It will not break during the pressing process of the top head 605. The surface of the polishing pad deforms during the pressing process of the top head 605. The deformation of the polishing pad is controlled by observing the scale on the adjusting rod 606, thereby changing the polishing effect on the workpiece. After determining the downward movement of the top head 605, the adjusting rod 606 is fixed by turning the fastening bolt 607. The position of the moving block 601 on the polishing disc 1 can also be changed by controlling the extension and retraction of the electric rod 609, thereby changing the polishing position.
