Description

Technical Field

[0001] The present application relates to the technical field of diamond water grinding discs, and more specifically, to an anti-wear flat polishing diamond water grinding disc. Background Art

[0002] Diamond water-grinding pads, also known as diamond soft grinding pads, are flexible processing tools made with diamond as the abrasive, combined with composite materials. Connected to the grinding block of a grinding machine, the diamond water-grinding pad, driven by the grinding machine, can be used to shape materials such as stone, ceramics, glass, and floor tiles. Diamond water-grinding pads are suitable for polishing stone, chamfering lines, processing curved slabs, and special-shaped stone. They can also be used for special-shaped processing of marble, concrete, cement floors, terrazzo, micro-ceramic glass, artificial stone, floor tiles, glazed tiles, and vitrified tiles.

[0003] In the related art, after grinding a relatively hard object, a traditional diamond grinding wheel may cause the surface of the object to be partially flattened due to the uneven surface of the object. This will cause the entire surface of the diamond grinding wheel to have a local depression, thereby affecting the subsequent grinding effect of the diamond grinding wheel. Utility Model Content

[0004] In view of this, an embodiment of the present application provides an anti-wear flat polishing diamond water grinding disc to solve the problem in the related art that the diamond water grinding disc is prone to cause depression on the surface when grinding relatively hard objects.

[0010] A positioning stud is provided, wherein the positioning stud passes through the positioning through hole and is threadedly connected to the threaded hole, and fixes the grinding plate body to the grinding block. An L-shaped piece is provided at the nut head of the positioning stud, and the L-shaped piece is inserted into the strip-shaped through hole to fix the fan-shaped grinding plate part in the first fan-shaped groove.

[0011] In some possible implementations, the thread length of the positioning stud is equal to the length of the threaded hole of the grinding plate body.

[0012] In some possible implementations, when the sector-shaped flange is located in the second sector-shaped groove, the surface of the sector-shaped grinding plate portion is flush with the lower surface of the grinding plate body.

[0013] In some possible implementations, the nut head of the positioning stud and the L-shaped piece are integrally formed, and the lower surface of the positioning stud is flush with the connecting surface of the L-shaped piece.

[0014] In some possible implementations, the lower surface of the sector-shaped grinding disc portion is provided with a first receiving groove adapted to the nut head of the positioning stud, and the nut head is located in the first receiving groove so that the lower surface of the nut head is flush with the lower surface of the grinding disc body.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figure 1-Figure 5As shown, the wear-resistant flat-polishing diamond water grinding disc provided in the embodiment of the present application includes a grinding block 100, a grinding disc body 200, a fan-shaped grinding disc portion 300 and a positioning stud 500, wherein the first surface of the grinding block 100 is connected to the grinder, and the lower surface of the grinding block 100, i.e., the second surface, is provided with a threaded hole 110, and the threaded hole 110 is located at the center position of the second surface of the grinding block 100.

[0028] The abrasive disc body 200 has a positioning hole 210 formed along its thickness, located at the center of the abrasive disc body 200. The first surface of the abrasive disc body 200 is connected to the second surface of the abrasive block 100. The lower surface, or second surface, of the abrasive disc body 200 has a first sector-shaped groove 220. A second sector-shaped recess 230 is further defined within the first sector-shaped groove 220. The area of the first sector-shaped groove 220 is larger than the area of the second sector-shaped recess 230.

[0029] The sector-shaped abrasive disc portion 300 is adapted to fit within the first sector-shaped groove 220 and is located within the first sector-shaped groove 220 of the abrasive disc body 200. Furthermore, a sector-shaped flange 400 is provided on the surface of the sector-shaped abrasive disc portion 300, which fits within the second sector-shaped recess 230. Furthermore, a strip-shaped through-hole 310 is provided at the end of the sector-shaped abrasive disc portion 300 near the center of the abrasive disc body 200.

[0030] In actual use, if it is necessary to grind an object with a relatively high hardness and an uneven surface, the sector-shaped flange 400 of the sector-shaped grinding disc portion 300 can be placed outward, and the sector-shaped flange 400 can be used to grind the object. After use, one side of the sector-shaped flange 400 can be placed in the second sector-shaped recess 230. This can prevent the object with a relatively high hardness and an uneven surface from causing significant wear to the grinding disc body 200, so that the surface of the grinding disc body 200 is no longer flat, thereby affecting the grinding effect.

[0031] In this embodiment, a positioning stud 500 is inserted into the positioning through-hole 210 of the grinding disc body 200. The positioning stud 500 passes through the positioning through-hole 210 and is threadedly connected to the threaded hole 110 of the grinding block 100. An L-shaped piece 700 is provided at the nut head 600 of the positioning stud 500. The L-shaped piece 700 is inserted into the strip-shaped through-hole 310 of the sector-shaped grinding disc portion 300 and secures the sector-shaped grinding disc portion 300 within the first sector-shaped groove 220.

[0032] In the wear-resistant flat polishing diamond water-grinding disc provided in the embodiment of the present application, if the diamond water-grinding disc is used to grind an object with an uneven and relatively hard surface, the sector-shaped flange 400 of the sector-shaped grinding disc portion 300 can be positioned outward, and then the L-shaped piece 700 of the positioning stud 500 is aligned with the strip-shaped through hole 310 of the sector-shaped grinding disc portion 300 and inserted, so as to fix the sector-shaped grinding disc portion 300 to the first sector-shaped groove 220 via the positioning stud 500. At this time, the positioning stud 500 passes through the positioning through hole 210 of the grinding disc body 200 and is located outside thereof, and then the grinding block 100 is connected to the grinding disc body 200 by a threaded connection. With the above structural design, the fan-shaped flange 400 of the fan-shaped grinding disc portion 300 can be used to grind objects with uneven surfaces and relatively hard objects. After use, the fan-shaped flange 400 can be fixed in the second fan-shaped recess 230, so as to ensure the flatness of the surface of the grinding disc body 200.

[0033] In some embodiments, the portion of the positioning stud 500 located in the positioning through hole 210 may not be provided with a threaded structure, and the thread length of the positioning stud 500 located in the threaded hole 110 is adapted to the length of the threaded hole 110 .

[0034] In some embodiments, the depth of the second fan-shaped recess 230 is equal to the thickness of the fan-shaped flange 400, so that when the fan-shaped flange 400 is located inside the second fan-shaped groove, the fan-shaped grinding plate portion 300 can be flush with the second surface of the grinding plate body 200, thereby ensuring the flatness of the grinding plate body 200.

[0035] In some embodiments, the nut head 600 of the positioning stud 500 and the L-shaped piece 700 are an integrally formed structure, and the lower surface of the positioning stud 500 is flush with the connecting surface of the L-shaped piece 700. This can not only ensure the structural firmness of the grinding plate body 200, but also ensure the flatness of the second surface of the grinding plate body 200.

[0036] In some embodiments, the lower surface of the sector-shaped abrasive disc portion 300 is provided with a first receiving groove 800 adapted to accommodate the positioning stud 500 and the nut head 600. The lower surface of the sector-shaped abrasive disc portion 300 is also provided with a second receiving groove 900 adapted to accommodate the L-shaped disc. The design of the first receiving groove 800 and the second receiving groove 900 allows the positioning stud 500 and the L-shaped disc 700 to be flush with the second surface of the abrasive disc body 200, thereby ensuring the grinding effect of the abrasive disc body 200.
