Description

Technical Field

[0001] The utility model relates to the technical field of abrasive tools, and more specifically, to a diamond elastic grinding block. Background Art

[0002] The diamond elastic grinding block is composed of a cutter head, an elastic rubber pad and a clamping plate, and is generally used for planar polishing of high-hardness non-metallic materials such as glazed ceramic tiles, microcrystalline glass plates, natural or artificial stones, etc. Because in the processes of forming, sintering, cutting, etc. of this kind of materials, problems such as uneven surface, edge and corner chipping, warping, etc. will inevitably occur, so when performing surface polishing, the polishing grinding block needs to have a certain profiling ability to polish the entire surface brightly. Otherwise, the decorative layer of the raised part will be ground off while the low-lying part will have no gloss. Existing methods: one is to reduce the hardness of the rubber pad to increase the deformation ability of the grinding block; the other is to groove the surface of the rubber pad to divide the surface of the rubber pad into several parts to increase the deformation ability of the grinding block. However, both of these methods have certain defects: the first method requires a large pressure to be applied to the grinding block to force the overall compression deformation of the rubber pad, resulting in an increase in the consumption of the grinding block and an increase in the polishing cost. Moreover, the resilience of the rubber itself is limited, and workpieces with large surface deformations need to be polished multiple times to meet the quality requirements; although the second method solves the defects of the first method, it brings new problems. It is necessary to divide the cutter head of the grinding block into several parts and paste them on the rubber pad one by one. This not only increases the manufacturing process and difficulty, but also because the single bonding area between the cutter head and the rubber pad is reduced and the bonding strength becomes low, it is very easy to fall off from the rubber pad, resulting in the failure of the grinding block. Therefore, it is necessary to further improve the existing technology. Summary of the Invention

[0003] The purpose of the utility model is to provide a diamond elastic grinding block with an island structure or a hollow structure rubber pad that is stable and reliable, increases the profiling ability of the grinding block while retaining the overall structure of the cutter head and does not affect the bonding strength between the cutter head and the rubber pad.

[0004] The utility model adopts the following technical solution to achieve the above purpose: A diamond elastic grinding block with an island structure or a hollow structure rubber pad, which is characterized in that it includes a cutter head, a rubber pad, and a clamping plate. The cutter head is arranged on the front surface of the rubber pad, and the rubber pad is arranged on the clamping plate;

[0005] On the back surface of the rubber pad, which is the bonding surface with the clamping plate, there are several grooves to divide it into multiple island structures; and / or, the middle part of the rubber pad adopts a hollow structure.

[0006] As a further illustration of the above scheme, the front side of the rubber pad has a certain curvature, which is the bonding surface of the cutter head. The bonding surface of the cutter head is not grooved. When the cutter head is bonded to the bonding surface, it is not necessary to cut the cutter head into several parts. The cutter head can be bonded to the rubber pad at one time, which reduces the number of steps and ensures that the cutter head and the rubber pad are firmly bonded. The back side of the rubber pad is an island structure or the middle part of the rubber pad is a hollow structure or a combination of an island structure and a hollow structure. The back side of the rubber pad is bonded to the cardboard.

[0007] Furthermore, the front side of the rubber pad is a curved structure with a high middle and low sides.

[0008] Furthermore, a cardboard bonding surface is provided on the back side of the rubber pad, and the rubber pad is bonded and fixed to the cardboard.

[0009] Furthermore, the back of the rubber pad is divided into unconnected island blocks by grooves, and these island blocks jointly support the curved surface of the rubber pad, which is referred to as an island structure. The dividing grooves can be 1 to N in each direction, and the cross-sectional shape of the grooves can be rectangular or other shapes. Another method is to set holes in the middle of the rubber pad, and keep a certain distance between the holes to form a wall thickness. The holes can be 1 or N in each direction, 1 layer or multiple layers, and the cross-sectional shape of the holes can be circular or rectangular or other shapes. The island structure or the hollow structure can be used alone or in combination.

[0010] Furthermore, the hole is a through hole, which passes through the front and rear ends of the rubber pad or the left and right sides of the rubber pad.

[0011] Furthermore, the card plate is provided with an embedding groove corresponding to the rubber pad, and the back side of the rubber pad is a flat structure, which is closely attached to the bottom of the embedding groove.

[0012] The beneficial effects that can be achieved by the utility model using the above technical solution are:

[0013] The utility model adopts a diamond elastic grinding block in the form of a rubber pad with an island structure and / or a hollow structure, and increases the profiling ability of the grinding block by changing the structure of the elastic rubber pad while retaining the overall structure of the cutter head. The cutter head does not need to be cut, and the cutter head can be bonded to the rubber pad at one time, which reduces the number of working steps and ensures that the cutter head and the rubber pad are firmly bonded.

[0029] The following further describes the specific embodiments of the present utility model in conjunction with the drawings of the specification, making the technical solutions and their beneficial effects of the present utility model clearer and more definite. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as limiting the present utility model. Embodiment

[0030] As Figures 1 - 2 shown, the present utility model is a diamond elastic grinding block using an island structure or a hollow structure rubber pad, which includes a cutter head 1, a rubber pad 2, and a clamping plate 3. The cutter head 1 is disposed on the front surface of the rubber pad 2, and the rubber pad 2 is disposed on the clamping plate 3. A cutter head bonding surface 2-1 is provided on the front surface of the rubber pad 2, and the cutter head is bonded to the cutter head bonding surface. A clamping plate bonding surface 2-2 is provided on the back surface of the rubber pad, and the rubber pad is bonded and fixed to the clamping plate. In this embodiment, the front surface of the rubber pad is an arc surface structure that is high in the middle and low on both sides. The clamping plate 3 is provided with an embedding groove 3-1 corresponding to the rubber pad, and the back surface of the rubber pad is a flat surface structure and closely adheres to the bottom of the embedding groove.

[0031] A number of grooves 2-3 are formed at the bottom of the rubber pad 2 to divide the rubber pad into a lower island-like structure. Since the elastic grinding block swings during operation instead of contacting the workpiece with the entire force-bearing surface, as the grinding block swings, the part of the grinding block in contact with the workpiece is constantly changing, so the pressure-bearing area of the rubber pad is also constantly changing. The rubber pad with an island-like structure has each independent area bearing the pressure of the grinding disc, thereby increasing the deformation amount and achieving a good profiling effect. Also, because there are gaps (grooves) between the islands, the rubber pad has a large space for compressive deformation, making the deformation of the rubber pad easier, and its rebound speed is faster, and the polishing effect on the low-lying surface is also better. Also, due to the adoption of the lower island-like structure, the part of the rubber pad adhered to the tool head is still a complete surface, and there is no need to cut the tool head. The tool head can be bonded to the rubber pad at one time, reducing the process and ensuring the firm bonding between the tool head and the rubber pad. Embodiment

[0032] As Figures 3 - 9 shown, in this embodiment, the rubber pad adopts a hollow structure. Some circular or rectangular or other-shaped holes 4 are made in the middle of the rubber. The holes are through holes, penetrating through the front and rear ends or the left and right sides of the rubber pad, facilitating the compressive deformation of the rubber pad, and keeping the upper surface and the lower surface of the rubber pad as a complete surface. The effect it achieves is similar to that of the rubber pad in Embodiment 1. Embodiment

[0033] As Figure 10 shown, in this embodiment, the lower island-like structure and the hollow-like structure can also be combined into a hollow lower island composite structure.

[0034] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the creative concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
