Description
Technical Field
[0001] This utility model belongs to the technical field of grinding equipment for disc cutting tools, specifically, it relates to a double grinding wheel device for grinding disc cutting tools. Background Technology
[0002] Diamond saw blades, due to their high hardness, high wear resistance, and long lifespan, are widely used in stone cutting, building material processing, and precision cutting of semiconductor materials. The production process of diamond saw blades encompasses key steps such as raw material pretreatment, molding, high-temperature bonding, finishing, and performance testing. The molded blanks require high-temperature consolidation or welding: in the hot-pressing sintering stage, the blanks are placed in a high-temperature sintering furnace to achieve a metallurgical bond between the diamond abrasive grains and the metal binder; the welding process employs advanced connection technologies such as high-frequency induction welding, laser cladding, or brazing to ensure a reliable connection between the cutting edge and the substrate. After high-temperature sintering or welding, the diamond saw blades enter the finishing stage. Grinding equipment and sandblasting techniques are used to sharpen and polish the working surface of the saw blade, removing machining residue and microscopic surface defects, thereby optimizing the edge smoothness and cutting efficiency. However, most existing sharpening machines are single-sided, which not only require flipping the saw blade but also have poor symmetry, resulting in inconsistent angles on both sides of the blade and affecting cutting stability. Therefore, there is a need for a double grinding wheel device for sharpening disc cutting tools that has high safety performance and can greatly improve sharpening efficiency and effect.

[0016] like Figure 1-4 As shown, a double-grinding wheel device for sharpening disc cutting tools includes a frame 1, a first ball screw mechanism 4, a second ball screw mechanism 5, a third ball screw mechanism 6, a first sliding seat 7, a left grinding wheel mechanism 8, and a right grinding wheel mechanism 9. The first ball screw mechanism 4 is vertically mounted on the frame 1, and the first sliding seat 7 is mounted on the first ball screw mechanism 4. The second ball screw mechanism 5 and the third ball screw mechanism 6 are both horizontally mounted on the first sliding seat 7. The left grinding wheel mechanism 8 is mounted on the second ball screw mechanism 5, and the right grinding wheel mechanism 9 is mounted on the third ball screw mechanism 6. The left grinding wheel mechanism 8 and the right grinding wheel mechanism 9 slide horizontally on the first sliding seat 7 and are symmetrically arranged.
[0017] The left grinding wheel mechanism 8 and the right grinding wheel mechanism 9 have the same structure, both including a second sliding seat 10, a bracket 11, a power motor 12, a first driving pulley 13, a first driven pulley 14, a transmission shaft 15, a grinding wheel shaft 16, and a grinding wheel 17. The bracket 11 is mounted on the second sliding seat 10, the power motor 12 is mounted on the bracket 11, the first driving pulley 13 is mounted on the output shaft of the power motor 12, the power motor 12 is arranged in the front-rear direction, the transmission shaft 15 is mounted on the lower part of the second sliding seat 10 and is arranged in the front-rear direction, the first driven pulley 14 is connected to the transmission shaft 15 by a corresponding key, the grinding wheel shaft 16 is connected to the rear end of the transmission shaft 15, the grinding wheel 17 is mounted on the grinding wheel shaft 16, the rear end of the grinding wheel shaft 16 is provided with a corresponding grinding wheel nut, the first driven pulley 14 is located below the first driving pulley 13, and the first driving pulley 13 and the first driven pulley 14 are connected by a corresponding transmission belt to form a belt drive mechanism. The left grinding wheel mechanism 8 and the right grinding wheel mechanism 9 are symmetrically arranged, but the grinding wheels 17 of the left grinding wheel mechanism 8 and the right grinding wheel mechanism 9 are not in the same plane. The staggered arrangement of the left and right grinding wheels 17 can further ensure the sharpening effect of the tool. When the two grinding wheels 17 are sharpening the tool in the same plane, the left and right sides of the same part of the tool are being ground at the same time, which will result in excessive grinding and poor sharpening effect.
[0018] The lower part of the second sliding seat 10 is provided with a first mounting block 18 corresponding to the drive shaft 15. The front end of the first mounting block 18 is equipped with a first pressure cap 19 by a corresponding round head screw. The first mounting block 18 and the drive shaft 15 are connected by a corresponding first bearing 20. The front end of the drive shaft 15 is provided with a corresponding bearing retaining ring 22.

A second spacer 26 is provided on the drive shaft 15, and the second spacer 26 is located in front of the second bearing 25.
[0020] A first wedge-shaped sliding part is vertically arranged on the frame 1, and a first wedge-shaped groove corresponding to the first wedge-shaped sliding part is provided on the first sliding seat 7.

The upper and lower inner walls of the second wedge groove are respectively equipped with an upper adjusting screw and a lower adjusting screw.
[0022] In practical use, the distance between the left grinding wheel mechanism 8 and the right grinding wheel mechanism 9 and the cutting tool is first adjusted by the second ball screw mechanism 5 and the third ball screw mechanism 6. After the adjustment is completed, the vertical position of the left grinding wheel mechanism 8 and the right grinding wheel mechanism 9 is adjusted by the first ball screw mechanism 4 so that the left side of the cutting tool to be ground contacts the grinding wheel of the left grinding wheel mechanism 8 and the right side of the cutting tool to be ground contacts the grinding wheel of the right grinding wheel mechanism 9. Then, the power motor 12 is started to drive the rotation of the two grinding wheels and cooperate with the corresponding clamping components to achieve double-sided grinding of the cutting tool.
[0023] It is worth noting that the first ball screw mechanism 4, the second ball screw mechanism 5, and the third ball screw mechanism 6 of this application are all ball screw mechanisms in the prior art. The first ball screw mechanism 4 is arranged vertically, and its purpose is to drive the first sliding seat 7 to move up and down. The second ball screw mechanism 5 and the third ball screw mechanism 6 are both arranged horizontally and are symmetrical left and right. The second ball screw mechanism 5 can drive the left grinding wheel mechanism 8 to move left and right, and the third ball screw mechanism 6 can drive the right grinding wheel mechanism 9 to move left and right.
[0024] This application features a simple structure, scientific principle, and convenient operation. By setting up a left grinding wheel mechanism 8 and a right grinding wheel mechanism 9, it achieves double-sided grinding of the cutting tool, greatly improving the grinding efficiency and effectively solving the technical problem of low grinding efficiency in existing methods. Furthermore, this application can adjust the up-down and left-right positions of the left grinding wheel mechanism 8 and the right grinding wheel mechanism 9 through a first ball screw mechanism 4, a second ball screw mechanism 5, and a third ball screw mechanism 6, thereby further improving the grinding efficiency and grinding effect by adjusting the distance between the grinding wheel and the cutting tool to be ground.
