[0001] The utility model belongs to the technical field of grinding machines, in particular to a water-based grinding machine. Background Art

[0002] PCD inserts are cutting tools made of polycrystalline diamond (PCD) material, which has remarkable hardness and wear resistance.

[0003] Sharpening PCD inserts requires the use of specialized diamond grinding wheels and high-precision sharpening machines; these devices can provide sufficient rigidity and precise control to accommodate the excessively hard nature of PCD materials.

[0004] When grinding PCD blades, dry grinding is generally used, which will produce a lot of grinding wheel dust. In addition, due to the high temperature of dry grinding of PCD tools, the grinding wheel will sinter and cannot sharpen the PCD tools. It will also cause harm to the human body and pollute the processing environment. Therefore, we proposed a water grinding wheel machine to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0024] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0025] Embodiment 1:

[0026] like Figure 1-Figure 2 As shown, the water grinding machine comprises a mounting frame 100, an upper mounting plate 101 is placed on the upper end of the mounting frame 100, a mounting box 102 is fixed to the middle of the upper end of the upper mounting plate 101, a bidirectional motor 103 is installed inside the mounting box 102, two output shafts of the bidirectional motor 103 pass through one end of the mounting box 102 and ceramic grinding wheels 104 are installed, a lower mounting plate 105 is installed on the lower side of the mounting frame 100, and a water spray assembly is provided between the mounting box 102 and the lower mounting plate 105;

[0027] The water spray assembly includes a water tank 200, which is installed on the upper end of the lower mounting plate 105. A water pump 201 is installed on the upper end of the lower mounting plate 105. A first water pipe 202 is connected between the water tank 200 and the water pump 201. A water diverter valve 203 is installed at the front end of the water tank 200. A second water pipe 204 is connected between the water pump 201 and the water diverter valve 203. Water valves 205 are symmetrically arranged on the upper end of the mounting box 102. Water diverter pipes 206 are respectively connected between the left and right ends of the water diverter valve 203 and the two water valves 205. The upper ends of the two water valves 205 are respectively connected with cooling pipes 207. Water spray heads 208 are arranged at the ends of the two cooling pipes 207. A reflux assembly is arranged between the upper mounting plate 101 and the water tank 200.

[0028] The mounting frame 100 can be installed with an upper mounting plate 101 and a lower mounting plate 105 to provide a mounting position for subsequent components. The upper mounting plate 101 can be installed with a mounting box 102, which can protect the bidirectional motor 103 from being affected by water and thus unable to operate normally. The bidirectional motor 103 can provide a power source and drive the two ceramic grinding wheels 104 to rotate, so that subsequent PCD blade grinding can be performed. The lower mounting plate 105 can be installed with a water tank 200 and a water pump 201. Water is stored in the water tank 200, and the water pump 201 can provide power for the flow of water. The first water pipe 202, the second water pipe 204, the two water distribution pipes 206 and the two cooling The pipes 207 provide paths and directions for the flow of cooling water. The water diversion valve 203 can divide the transported cooling water into the two water diversion pipes 206 respectively. The water valve 205 can control the opening or closing between the water diversion pipe 206 and the cooling pipe 207, which is convenient for the control of the cooling water. The cooling pipe 207 is set with a fixed pipe, which is convenient for the staff to bend it at will, so that the water spray head 208 can be accurately aligned with the grinding position, thereby improving the effects of extinguishing sparks, lowering temperature, and cleaning dust. The water spray head 208 can spray cooling water, thereby cooling the grinding position, and the falling cooling water will pass through the reflux component and return to the water tank 200 again, so that the cooling water can be recycled and resources can be saved.

[0029] When grinding the PCD blade: first, the water grinding machine is connected to an external power source, and then the bidirectional motor 103 is started. The two output shafts of the bidirectional motor 103 will drive the two ceramic grinding wheels 104 to rotate synchronously. Finally, the staff can grind the PCD blade. During the grinding process, sparks, high temperature and dust will be generated at the contact position between the PCD blade and the ceramic grinding wheel 104. At the same time, the water pump 201 is started. The water pump 201 can extract the cooling water stored in the water tank 200 and make the cooling water flow. Relying on the first water pipe 202 and When the second water pipe 204 delivers cooling water to the position of the water diverter valve 203, the water diverter valve 203 can divide the cooling water into two parts, which are respectively delivered to the corresponding cooling pipes 207 through two water diverter pipes 206. When the cooling water is sprayed out from the water spray head 208, the grinding position can be cooled by the cooling water. In the process of cooling water spraying, not only the grinding position can be cooled, but also the dust generated during grinding can be mixed with the cooling water and taken away. In this way, the damage to the workpiece and the grinding wheel caused by the heat generated by grinding can be reduced, and the dust generated by grinding can be washed away to keep the grinding surface clean.

[0030] In this embodiment, by starting the water pump 201, the cooling water inside the water tank 200 is pumped out, and the cooling water is guided and transported by relying on the first water pipe 202, the second water pipe 204, the two water distribution pipes 206 and the two cooling pipes 207, so that the cooling water can be sprayed out from the water nozzle 208, thereby effectively reducing the temperature during the grinding process, preventing the ceramic grinding wheel 104 from sintering due to friction overheating, extending the service life of the ceramic grinding wheel 104, reducing dust, and optimizing the working environment.

[0031] Embodiment 2:

[0032] Based on the first embodiment, other components of the water grinding machine are further described. Figure 1-Figure 3 As shown, the reflux component includes a material receiving box 300, which is fixedly connected to the middle part of the lower end of the upper mounting plate 101, and water receiving grooves 301 are symmetrically provided on the left and right sides of the upper end of the upper mounting plate 101. A guide groove 302 connected to the material receiving box 300 and the two water receiving grooves 301 is provided inside the upper mounting plate 101, and the lower end of the material receiving box 300 is connected to a water inlet pipe 303, and the water inlet pipe 303 extends into the water tank 200, and a filter component is provided inside the material receiving box 300.

[0033] The filter assembly includes a water receiving box 304 . A groove is provided at the rear end of the receiving box 300 . The water receiving box 304 is slidably arranged inside the groove. A sponge pad 305 is placed inside the water receiving box 304 .

[0034] Support columns 400 are symmetrically arranged at the bottom of the two water receiving tanks 301 , and support plates 401 are fixed to the upper ends of the two support columns 400 .

[0035] A power switch 402 is installed at the rear end of the installation box 102 , a connecting tube 403 is provided at the upper end of the installation box 102 , and a lighting lamp 404 electrically connected to the power switch 402 is provided at the end of the connecting tube 403 .

[0036] N-shaped waterproof covers 405 surrounding the ceramic grinding wheel 104 are respectively provided at the left and right ends of the installation box 102.

[0037] In this embodiment, when cooling water mixed with dust falls into the water receiving groove 301, the cooling water will flow into the receiving box 300 along the guide groove 302 along with the dust. When passing through the sponge pad 305, the dust in the cooling water can be filtered to obtain clean cooling water, which is then transported to the water tank 200 through the water inlet pipe 303. In this way, the cooling water can be recycled and resources can be saved.

[0038] When the staff is grinding the PCD blade, they can put the PCD blade on the upper end of the support plate 401 and slowly move it toward the ceramic grinding wheel 104. This can avoid the staff from holding the PCD blade for grinding and reduce the staff's labor intensity.

[0039] After the water-grinding grinder is connected to an external power source, the power switch 402 can be used to control the on or off of the lighting lamp 404, so that the staff can grind the PCD blade more carefully. The connecting pipe 403 uses a shaped pipe, which can be bent at will according to the needs of the staff, and the position of the lighting lamp 404 can be adjusted, so that the staff can grind the PCD blade better.

[0040] The N-shaped waterproof cover 405 can effectively block splashing objects and prevent harm to workers.
