Description

Technical Field

[0001] The utility model relates to the field of abrasive saw blade equipment, in particular to a multi-layer abrasive saw blade. Background Technique

[0002] There are two commonly used sawing super-hard tools on the market, namely, a grinding wheel with brown fused alumina as the abrasive and a saw blade with diamond as the abrasive. When the existing abrasive saw blade grinds materials, it directly grinds the grinding position through the saw blade. Direct grinding will damage the saw blade at the ultra-fine grinding position, and the existing saw blade cannot quickly switch between rough grinding and fine grinding.

[0003] According to a composite abrasive saw blade disclosed in a patent document with the existing publication number CN201419363Y, it includes a metal matrix, an abrasive is provided on the metal matrix, an inlay groove is provided on the metal matrix, and a ceramic-based cubic boron nitride composite abrasive is provided in the inlay groove. The inlay groove is a toothed inlay groove or a rectangular inlay groove or an annular inlay groove. The width L of the inlay groove is between 3 and 10 millimeters. The metal matrix is an aluminum alloy matrix or a steel matrix. When this technical solution is used, the cubic boron nitride composite abrasive has low energy consumption and does not pollute the environment during the production process. The used matrix is a metal matrix with high strength, which ensures that the saw blade will not break even during high-speed rotation during use, which not only improves the cutting efficiency but also ensures the safety of operation. For the above technical solution, although the safety of operation is achieved, the saw blade cannot be quickly disassembled and replaced during use, which is inconvenient during use. Content of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a multi-layer abrasive saw blade to solve the problems raised in the above background technique. The structure of the utility model is novel. During use, the movable disk pushes the fixed seat and the movable seat to move upward, the top of the movable seat is separated from the support seat, and the fixed seat and the movable seat are disassembled by tools. After disassembly, the movable disk and the grinding block can be replaced.

[0005] In order to achieve the above purpose, the utility model is realized by the following technical solutions: a multi-layer abrasive saw blade, including a saw blade body, the saw blade body includes a fixed disk, a movable disk is movably installed on the top of the fixed disk, a fixed seat is fixed on the movable disk, a movable seat is movably installed inside the fixed seat, a support seat is movably installed inside the movable seat, one end of the support seat is fixed on the fixed disk, an installation hole is opened between the fixed disk and the support seat, and a slot is opened on the fixed disk.

[0006] Furthermore, a grinding block is movably installed inside the slot, and the grinding block is fixed on one side of the movable disk.

[0007] Further, a grinding ring is brazed on one side of the fixed disk, a threaded hole is formed in the inner wall of the fixed seat, and a through hole is formed in the inner wall of the movable seat.

[0008] Further, a limiting groove is formed on the side of the support seat, and a support mechanism is fixedly installed inside the limiting groove.

[0009] Further, a limiting block is fixed at one end of the support mechanism, the limiting block is movably installed inside the limiting groove, and one side of the limiting block is fixed on the fixed seat.

[0010] Further, a fixing bolt is rotatably installed inside the through hole and the threaded hole.

[0012] 1. When the multi-layer abrasive saw blade is in use, the movable disk pushes the fixed seat and the movable seat to move upward, the top of the movable seat is separated from the support seat, and the fixed seat and the movable seat are disassembled by a tool. After disassembly, the movable disk and the grinding block can be replaced.

[0013] 2. For the multi-layer abrasive saw blade, before grinding, the grinding block first contacts the grinding location, and the grinding position is roughly ground by the grinding block.

Detailed implementation manners

[0019] To make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.

[0020] Please refer to Figures 1 to 3 , the present utility model provides a technical solution: a multi-layer abrasive saw blade, including a saw blade body. The saw blade body includes a fixed disk 1. A movable disk 2 is movably installed on the top of the fixed disk 1. A fixed seat 3 is fixed on the movable disk 2. A movable seat 4 is movably installed inside the fixed seat 3. A support seat 5 is movably installed inside the movable seat 4. One end of the support seat 5 is fixed on the fixed disk 1. An installation hole is formed between the fixed disk 1 and the support seat 5. A slot 14 is formed on the fixed disk 1. A grinding block 7 is movably installed inside the slot 14. The grinding block 7 is fixed on one side of the movable disk 2. The hardness of the grinding block 7 is greater than that of the grinding ring 6, and it can grind and remove harder burrs.

[0021] In this embodiment, a grinding ring 6 is brazed on one side of the fixed disk 1. A threaded hole 8 is formed on the inner wall of the fixed seat 3. An opening 10 is formed on the inner wall of the movable seat 4. A limiting groove 11 is formed on the side of the support seat 5. A support mechanism 12 is fixedly installed inside the limiting groove 11. One end of the support mechanism 12 is fixed with a limiting block 13. The limiting block 13 is movably installed inside the limiting groove 11. One side of the limiting block 13 is fixed on the fixed seat 3. A fixing bolt 9 is rotatably installed inside the opening 10 and the threaded hole 8. The support mechanism 12 is a support spring. The support spring pushes the limiting block 13 to move downward. In the case where there is no extrusion force on the grinding block 7, the support mechanism 12 pushes the movable disk 2 to quickly return downward.

[0022] When the device is in use, the fixed disk 1 is fixedly installed on a grinding hand-held motor through the support seat 5 and the installation hole. When in use, the installation of the fixed disk 1 and the support seat 5 is realized through bolts. During grinding, the grinding block 7 contacts the grinding point first. The hardness of the grinding block 7 is greater than that of the grinding ring 6, and it can grind and remove harder burrs. In addition, the gap of the grinding block 7 is large, and it can perform rough grinding on the grinding location. After the rough grinding of the grinding block 7, fine grinding is realized through the grinding ring 6, thereby avoiding damage to the saw blade caused by directly grinding through the grinding ring 6. When the grinding block 7 is opened, the fixed disk 1 and the movable disk 2 are pressed. The grinding block 7 contracts into the slot 14, and the grinding ring 6 contacts the grinding position for fine grinding. The grinding fineness is adjusted according to different situations. Under the push of the grinding block 7, the movable disk 2 pushes the fixed seat 3 and the movable seat 4 to move upward. After the movable seat 4 moves upward, it separates from the top of the support seat 5. After removing the fixing bolt 9 with a tool, the fixed seat 3 and the movable seat 4 can be disassembled. After disassembly, the movable disk 2 and the grinding block 7 can be replaced.
