Description

Technical Field

[0001] The utility model relates to the technical field of polishing abrasive blocks, in particular to a fully-fitting elastic abrasive block. Background Art

[0002] Since elastic grinding blocks have the characteristics of good profiling effect, strong grinding ability, high glaze gloss and no wear marks, elastic grinding blocks are usually used to perform profiling full polishing or semi-polishing on antique tiles, polished crystal tiles and glazed tiles. Figure 1 The elastic grinding block shown is used to polish the brick surface of the above brick type. The elastic grinding block is composed of a clamping seat 10', a rubber pad installed on the clamping seat 10', and a grinding tooth installed on the rubber pad. The rubber pad is set as an integral rubber pad 20' with an integral block structure, and the grinding teeth are set as square and large square grinding teeth 30' with a larger overall area. The side length of the large square grinding teeth 30' is 15×13mm, so the brick surface is polished by the large square grinding teeth 30'.

[0003] Although the elastic grinding block with large square grinding teeth can perform basic polishing on the brick surface, it still has the following defects:

[0004] 1. Due to the adjustment of the formula of the brick blank or the inadequate processing of the brick blank in the early stage, the brick surface may be uneven. When the brick surface is polished, due to the low deformation capacity of the integral rubber pad 20' itself, when the grinding disc applies pressure to the elastic grinding block to make the large square grinding teeth 30' polish the brick surface, the compression deformation effect of the large square grinding teeth 30' on the integral rubber pad 20' is also poor, resulting in the large square grinding teeth 30' being unable to fully fit onto the brick surface, and then being unable to perform compression deformation polishing on the uneven brick surface, which is prone to omission and polishing, and the polishing quality is poor; in addition, the production and manufacturing consumables of such integral rubber pads 20' and large square grinding teeth 30' are relatively large, and the manufacturing cost is relatively high.

[0005] 2. The existing elastic grinding block is provided with large square grinding teeth 30'. Under the condition of ensuring that the total contact area between the elastic grinding block and the brick surface remains unchanged, the number of grinding teeth provided on the elastic grinding block is relatively small, and the contact area between a single large square grinding tooth 30' and the brick surface is large, so that the number of contact points between the elastic grinding block and the brick surface is also small; therefore, the large square grinding teeth 30' cannot penetrate into the concave and convex parts of the brick surface for polishing, which leads to missed polishing, or it takes a longer time to polish the convex parts before polishing the concave parts, but it is easy to have the problem of polishing through, and even damage the whole brick blank, and when the contact area between a single grinding tooth and the brick surface is large, the grinding chips or debris generated by the polishing process are easy to remain between the grinding teeth and the brick surface, and the chip removal effect is not good. These grinding chips or debris will cause obvious rough wear marks and scratches on the brick surface during polishing; in addition, due to the small number of large square grinding teeth 30' and the small number of contact points with the brick surface, the polishing quality of the brick surface is affected. Utility Model Content

[0006] In order to overcome the deficiencies of the prior art, the utility model aims to provide a fully-fitting elastic grinding block.

[0007] The purpose of the utility model is achieved by adopting the following technical scheme: a fully-fitted elastic grinding block, comprising a holder, an elastic pad and a polishing grinding tooth, wherein the elastic pad is arranged above the holder, and the working surface of the elastic pad has a plurality of connecting columns arranged in an array, a deformation gap is provided between two adjacent connecting columns, and the ends of a plurality of the connecting columns have a connecting surface; the polishing grinding tooth comprises a plurality of columnar grinding tooth portions and a mounting block connecting the columnar grinding tooth portions, the columnar grinding tooth portions are arranged in an array, and the polishing grinding tooth is fixedly connected to the connecting surface of the connecting column through the mounting block.

[0008] Furthermore, the elastic pad includes a connecting portion fixed on the base, the connecting column is formed by vertically extending upward from the top of the connecting portion, the connecting portion and the connecting column are integrally formed, and the connecting column is configured to be cylindrical or square columnar.

[0009] Furthermore, the thickness of the connecting portion is 5-8 mm, and the length of the connecting column is 8-11 mm.

[0010] Furthermore, the diameter of the cylindrical connecting column is 6.5-10 mm, or the side length of the square column connecting column is 6.5-10 mm.

[0011] Furthermore, a plurality of the connecting posts are arranged in a rectangular array on the working surface of the elastic pad, so that the plurality of the connecting posts form deformation gaps in longitudinal and transverse directions on the working surface of the elastic pad.

[0012] Furthermore, the columnar grinding gear portion is cylindrical.

[0013] Furthermore, the diameter of the columnar grinding portion is 9-10 mm.

[0014] Furthermore, the ratio of the end surface area of ​​each columnar grinding tooth portion to the end surface area of ​​the connecting column is (1-1.2):1.

[0015] Furthermore, a plurality of the columnar grinding teeth are arranged in a rectangular array on the surface of the mounting block, so that the plurality of columnar grinding teeth form longitudinal and transverse chip removal grooves on the surface of the mounting block.

[0016] Furthermore, the width of the chip removal groove is 3-5 mm, and the width of the longitudinal chip removal groove is equal to that of the transverse chip removal groove.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] (1) A plurality of connecting columns are arranged on the working surface of the elastic pad of the fully-fitting elastic grinding block of the present application, and the plurality of connecting columns are arranged at a distance to form a deformation gap, so that the plurality of connecting columns can be compressed and deformed freely when subjected to force, and will not interfere with adjacent connecting columns; when the polishing teeth are arranged on the connecting surface of the connecting columns, and the grinding disc applies pressure to the fully-fitting elastic grinding block to perform contour polishing on the brick surface, the plurality of connecting columns can be compressed and deformed freely, and the polishing teeth can also be compressed and deformed following the connecting columns, so that the columnar grinding teeth of the plurality of polishing teeth can be fully fitted with the brick surface for polishing;

[0019] Combined with the columnar structure of the columnar grinding teeth, it can better perform efficient profiling polishing on the concave and convex parts of the brick surface, avoiding the problems of missed polishing, polishing through and incomplete fit with the brick surface when the elastic grinding block uses an integral rubber pad and large square grinding teeth for polishing in the past, thereby improving the profiling polishing quality of the brick surface;

[0020] In addition, by providing a plurality of connecting columns arranged in an array on the working surface of the elastic pad and configuring the columnar grinding portion as a columnar structure, the material of the elastic pad and the polishing grinding teeth can be saved, thereby reducing the manufacturing cost.

[0021] (2) By setting the columnar grinding teeth of the polishing grinding teeth to a cylindrical structure with a diameter of 9-10 mm, compared with the conventional large square grinding teeth with a side length of 15×13 mm, the fully-fitting elastic grinding block of the present application can be provided with more cylindrical columnar grinding teeth, so that more columnar grinding teeth can be used to contact the brick surface, and the number of contact points on the brick surface is greater, so that the columnar grinding teeth can perform efficient and high-quality profiling polishing on each concave and convex part of the brick surface, further avoiding the problems of missed polishing and polishing through;

[0022] In addition, the single cylindrical grinding tooth part provided by the present application has a smaller contact area with the brick surface. When the brick surface is profiled and polished, the grinding chips cannot remain on the cylindrical grinding tooth part with a smaller area, and the generated grinding chips can be discharged more smoothly from the longitudinal and transverse chip discharge grooves between the cylindrical grinding tooth parts. This avoids the problem that the large square grinding teeth have a large contact area with the brick surface and are prone to residual grinding chips, so that the grinding chips affect the profile polishing of the brick surface, and further improve the profile polishing quality of the brick surface.

[0032] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0033] like Figure 2-4 As shown, a fully-fitted elastic grinding block is used for performing full-polishing or semi-polishing processing on the surfaces of antique tiles, polished crystal tiles and glazed tiles. The ring-fitted elastic grinding block includes a holder 10, an elastic pad 20 and polishing teeth 30, wherein the holder 10 serves as a carrier fixedly connected to the grinding disc, the lower part of the holder 10 is dovetail-shaped for assembly with the grinding disc, and the upper part of the holder 10 is concave to form a mounting groove 101 for mounting the elastic pad 20.

[0034] The lower part of the elastic pad 20 is installed in the installation groove 101 on the upper part of the card seat 10, so that the elastic pad 20 is arranged above the card seat 10, and the top of the elastic pad 20 is arranged as a working surface. A plurality of connecting columns 201 are arranged on the working surface of the elastic pad 20. Specifically, the connecting columns 201 are arranged to extend vertically upward on the working surface of the elastic pad 20. The connecting columns 201 are arranged in a cylindrical or square column shape and are integrally formed with the elastic pad 20.

[0035] The lower part of the elastic pad 20 is the connecting part 200, and the thickness of the connecting part 200 is 5-8 mm. The length of the connecting column 201 extending vertically upward from the working surface of the elastic pad 20 is 8-11 mm. When the connecting column 201 is set to a cylindrical shape, its diameter is 6.5-10 mm. When the connecting column 201 is set to a square column shape, its side length is 6.5-10 mm. In addition, a plurality of connecting columns 201 are arranged in a rectangular array on the working surface, so that a certain width of gap is left between adjacent connecting columns 201.

[0036] Therefore, when a plurality of connecting columns 201 are arranged in a rectangular array on the working surface, the plurality of connecting columns 201 are arranged in a plurality of rows in the longitudinal and transverse directions of the working surface, so that the plurality of connecting columns 201 form deformation gaps 202 in the longitudinal and transverse directions on the working surface.

[0037] By forming the deformation gaps 202 in the longitudinal and transverse directions on the working surface of the elastic pad 20, it is possible to avoid mutual interference between the plurality of connecting columns 201 during the compression deformation of the profiling polishing, thereby avoiding affecting the profiling polishing quality of the brick surface.

[0038] The ends of the connecting posts 201 all have arcuate surfaces, and the arcuate surfaces of several connecting posts 201 mutually constitute a connecting surface 203 for assembling the polishing grinding gear 30. Since the connecting surface 203 is composed of the arcuate surfaces of several connecting posts 201, the connecting surface 203 is also arc-shaped.

[0039] The polishing teeth 30 are provided in a plurality, and the polishing teeth 30 include a columnar grinding tooth portion 300 and a mounting block 301. The columnar grinding tooth portion 300 is arranged in an array on the mounting block 301. The upper end of the columnar grinding tooth portion 300 is a polishing end, and the lower end of the columnar grinding tooth portion 300 is a connecting end. Therefore, the lower ends of the plurality of columnar grinding tooth portions 300 are connected to the mounting block 301, so that the plurality of columnar grinding tooth portions 300 are arranged in an array on the mounting block 301.

[0040] The mounting block 301 is an arc-shaped block and matches the connecting surface 203 of the connecting column 201, so that a plurality of columnar grinding teeth 300 are glued and connected to the connecting surface 203 of the connecting column 201 through the mounting block 301, thereby assembling the polishing grinding teeth 30 on the elastic pad 20, and during the contour polishing process, the polishing grinding teeth 30 can follow the connecting column 201 of the elastic pad 20 for compression deformation.

[0041] In this way, the plurality of connecting posts 201 provided by the present application are arranged at intervals on the working surface of the elastic pad 20 to form a deformation gap 202, so that the plurality of connecting posts 201 can be freely compressed and deformed when subjected to force, and will not interfere with adjacent connecting posts 201. When the polishing teeth 30 are arranged on the connecting surface 203 of the connecting posts 201, and the grinding disc applies pressure to the fully-fitting elastic grinding block to perform contour polishing on the brick surface, the plurality of connecting posts 201 can be freely compressed and deformed, and the polishing teeth 30 can also be compressed and deformed following the connecting posts 201, so that the columnar grinding teeth 300 of the plurality of polishing teeth 30 can all be fully fitted with the brick surface for polishing.

[0042] Combined with the columnar structure of the columnar grinding tooth part 300, it is possible to better perform efficient profiling polishing on the concave and convex parts of the brick surface, avoiding the problems of missed polishing, polishing through, and incomplete fit with the brick surface when the elastic grinding block uses an integral rubber pad and a large square grinding tooth for polishing in the past, thereby improving the profiling polishing quality of the brick surface. In addition, by arranging a plurality of columnar connecting columns 201 in an array on the working surface of the elastic pad 20, and setting the columnar grinding tooth part 300 as a cylindrical columnar structure, it is possible to save materials for the elastic pad 20 and the polishing grinding tooth 30, thereby reducing the manufacturing cost.

[0043] In the embodiment of the present application, the cylindrical grinding tooth portion 300 is preferably set to a cylindrical shape, and the contact end of the cylindrical grinding tooth portion 300 with the brick surface is a circular grinding tooth. The circular grinding tooth can be more easily attached to the brick surface than the square grinding tooth, and it is convenient to go deep into the concave and convex parts of the brick surface for polishing. More specifically, the diameter of the cylindrical grinding tooth portion 300 is set to 9-10mm, and the preferred diameter is 9.2mm, 9.5mm, and 9.8mm. By replacing the cylindrical grinding tooth portion 300 with different diameter specifications, it can be suitable for the brick surface profiling polishing of different sizes of concave and convex parts.

[0044] According to the size design of the connecting column 201 and the columnar grinding tooth portion 300, the ratio of the end area of ​​each columnar grinding tooth portion 300 to the end area of ​​each connecting column 201 is (1-1.2):1. By controlling the end area ratio of the two within this ratio range, the polishing grinding tooth 30 can achieve the optimal compression deformation effect when following the connecting column 201 for compression deformation.

[0045] In this way, by setting the columnar grinding tooth portion 300 of the polishing grinding tooth 30 to a cylindrical structure with a diameter of 9-10mm, compared with the previous large square grinding teeth with a side length of 16×13mm, more cylindrical columnar grinding tooth portions 300 can be set on the fully-fitting elastic grinding block of the present application, so that more columnar grinding tooth portions 300 can be used to contact the brick surface, and the number of contact points on the brick surface is greater, so that the columnar grinding tooth portion 300 can perform efficient and high-quality contour polishing on each concave and convex part of the brick surface, further avoiding the problems of missed polishing and polishing through.

[0046] Regarding the optimized design of the polishing grinding teeth 30 , more specifically, a plurality of columnar grinding teeth portions 300 are arranged in a rectangular array on the surface of the mounting block 301 , so that a certain width of gap is left between adjacent columnar grinding teeth portions 300 .

[0047] Therefore, when a plurality of columnar grinding teeth 300 are arranged in a rectangular array on the surface of the mounting block 301, the plurality of columnar grinding teeth 300 are arranged in a plurality of rows in the longitudinal and transverse directions on the mounting block 301, so that the plurality of columnar grinding teeth 300 form a longitudinal and transverse chip removal groove 32 on the surface of the mounting block 301, and roughly form 5 longitudinal rows and 10 transverse rows of columnar grinding teeth 300 on the surface of the mounting block 301, and the longitudinal chip removal groove 32 is equal to the transverse chip removal groove 32 in width, and the groove width is set to 3-5mm, so that the grinding chips and debris can be discharged more smoothly. When the brick surface is profiled and polished, the generated grinding chips can be discharged through the longitudinal and transverse chip removal groove 32.

[0048] In this way, the single cylindrical grinding tooth part 300 provided by the present application has a small contact area with the brick surface, and during the profiling polishing of the brick surface, the grinding chips cannot remain on the cylindrical grinding tooth part 300 with a small area, and the generated grinding chips can be more smoothly discharged from the chip discharge grooves 32 of the longitudinal and transverse directions between the cylindrical grinding tooth parts 300. The problem of large contact area between the large square grinding teeth and the brick surface and easy residue of grinding chips is avoided, thereby preventing the grinding chips from affecting the profiling polishing of the brick surface, and further improving the profiling polishing quality of the brick surface.

[0049] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
