[0016] 1. The drained water enters the water guide groove and then returns to the inside of the water tank through the drain pipe. The water discharged from the drain pipe will first be filtered by the filter hole of the filter hole, and then enter the water tank for secondary utilization. Nitrate is placed in the material box through the first opening. When the working environment is hot and the water in the water tank needs to be cooled, the output end of the second cylinder retracts and the first rod rotates clockwise. At this time, the first baffle moves along the limit bar, and then drives the second rod to rotate. Since the teeth of the two second rods are meshed, the two second rods will rotate relative to each other. Therefore, the two baffles at this time move in the opposite direction along the limit bar to open the second opening, and then the nitrate in the material box falls into the water tank from the second opening.

[0017] 2. The motor starts to drive the worm to rotate, and then the worm wheel and the shaft rotate. The rotation of the shaft drives the stirring blade and the inclined column to rotate. The rotation of the stirring blade facilitates the stirring of nitrate and water, so that the nitrate quickly dissolves in the water to absorb heat to achieve water cooling, and then the sprayed water is cooling water suitable for summer use. Since the vertical rod is located in the inclined slot and there is a height difference in the inclined slot, the rotation of the inclined column will drive the pad and the top block to rise through the vertical rod, and then the pad will penetrate the filter hole to prevent the filter hole from being blocked. The spring facilitates the pad to reset and fall after it rises.

[0018] 3. Place the bearing inside the three clamps, then retract the output end of the first cylinder to drive the disc down. When the disc descends, it drives the connecting rod to rotate, and then the three clamps rotate to clamp the bearing. BRIEF DESCRIPTION OF THE DRAWINGS

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The following is an explanation of its embodiments based on the overall structure of the present invention.

[0029] A bearing inner diameter grinding device comprises: a main body 1, wherein the main body 1 comprises a clamping mechanism 2 and a grinding wheel 38, wherein the clamping mechanism 2 comprises a hollow seat 3, wherein a first cylinder 4 is fixedly installed inside the hollow seat 3, wherein an output end of the first cylinder 4 passes through the hollow seat 3 and is fixed with a disc 5, wherein one end of the hollow seat 3 is rotatably connected with three clamping jaws 6, wherein one end of the disc 5 is rotatably connected with a connecting rod 7, and one end of the connecting rod 7 is rotatably connected with the clamping jaws 6, wherein the bearing is placed inside the three clamping jaws 6, and then the output end of the first cylinder 4 is retracted to drive the disc 5 to descend, and when the disc 5 descends, the connecting rod 7 is driven to rotate, and then the three clamping jaws 6 are rotated to clamp the bearing, and then the working grinding wheel 38 of the internal cylindrical grinder enters the inner diameter of the bearing to grind its inner diameter,

[0030] Furthermore, a first nozzle 8 and a second nozzle 9 are installed on the top of the main body 1, the first nozzle 8 is an atomizing nozzle, the first nozzle 8 and the second nozzle 9 are connected with two hoses, the bottom of the hoses are located inside the water tank 10, a water pump is installed inside the main body 1, and the two hoses are connected to the water pump, the water tank 10 and the material box 11 are arranged inside the main body 1, nitrate is stored inside the material box 11, a first opening 12 is arranged on the top of the material box 11, and a second opening 13 and a third opening 14 that cooperate with each other are arranged at the bottom of the material box 11 and the top of the water tank 10,

[0031] It can be concluded that waste chips will be generated during processing. At this time, the water pump is started and then the clean water in the water tank 10 is discharged to the inside of the first nozzle 8 and the second nozzle 9 through two hoses. The first nozzle 8 sprays water into atomized form to reduce chips and prevent workers from inhaling a large amount of water and affecting their health. The water sprayed by the second nozzle 9 rushes to the grinding wheel 38 to cool the grinding wheel 38.

[0032] Furthermore, the bottom of the material box 11 is rotatably connected to a second cylinder 15 and fixed with a limit bar 16, the limit bar 16 is internally slidably connected to two baffles 17, the bottom of one of the baffles 17 is rotatably connected to a first rod 18, the output end of the second cylinder 15 is rotatably connected to the first rod 18, the bottom of the material box 11 is rotatably connected to a second rod 19, one end of the second rod 19 is rotatably connected to the baffle 17, and the other end of the second rod 19 is fixed with a tooth 20.

[0033] Next, a filter frame 21 is fixed inside the water tank 10, and a filter hole 22 is set at the bottom of the filter frame 21. The workbench of the main body 1 is connected to a drain pipe 23, and the end of the drain pipe 23 is located in the filter frame 21. The inner wall of the water tank 10 is slidably connected with a pad 24 in the vertical direction, and a top block 25 is fixed on the top of the pad 24. A spring 26 is fixed on the top of the pad 24, and the top of the spring 26 is fixedly connected to the bottom of the filter frame 21. A worm gear 31 is rotatably connected to the bottom of the inner cavity of the water tank 10, and a rotating shaft 27 is fixed on the top of the worm gear 31. The interior of the water tank 10 provides a rotation support force for the rotating shaft 27 through a support block 28, and a stirring blade 32 is set outside the rotating shaft 27. An inclined column 33 is fixed on the top of the rotating shaft 27, and an inclined groove 34 is set on the top of the inclined column 33. The workbench is provided with a water guide groove. The drained water enters the water guide groove and then returns to the inside of the water tank 10 through the drain pipe 23. The water discharged from the drain pipe 23 will first be filtered by the filter hole 22 of the filter frame 21, and then enter the water tank 10 for secondary utilization after filtration. Nitrate is placed in the material box 11 through the first opening 12. When the working environment is hot and the water in the water tank 10 needs to be cooled, the output end of the second cylinder 15 retracts and then the first rod 18 rotates clockwise. At this time, the first baffle 17 moves along the limit bar 16, and then drives the second rod 19 to rotate. Since the teeth 20 of the two second rods 19 are meshed, the two second rods 19 will rotate relative to each other. Therefore, the two baffles 17 at this time move in the opposite direction along the limit bar 16 to open the second opening 13, and then the nitrate in the material box 11 falls from the second opening 13 into the water tank 10.

[0034] Next, a vertical rod 35 is fixed to the bottom of the pad 24, and the bottom of the vertical rod 35 is located inside the chute 34. A motor 36 is fixedly installed at the bottom of the main body 1. A worm 37 meshing with the worm gear 31 is rotatably connected inside the water tank 10. The output end of the motor 36 is fixedly connected to one end of the worm 37. At the same time, the motor 36 starts to drive the worm 37 to rotate, and then the worm gear 31 and the rotating shaft 27 rotate. The rotation of the rotating shaft 27 drives the stirring blade 32 and the inclined column 33 to rotate. The rotation of the stirring blade 32 facilitates the stirring of nitrate and water, so that the nitrate quickly dissolves in the water to absorb heat and realize the cooling of the water. Then the sprayed water is cooling water suitable for use in summer. Since the vertical rod 35 is located in the chute 34 and there is a height difference in the chute 34, the rotation of the inclined column 33 will drive the pad 24 and the top block 25 to rise through the vertical rod 35, and then the pad 25 penetrates the filter hole 22 to prevent the filter hole 22 from being blocked. The spring 26 facilitates the pad 24 to reset and fall after it is raised.

[0035] Working principle: put the bearing into the inside of the three clamps 6, then the output end of the first cylinder 4 retracts to drive the disc 5 to descend, and when the disc 5 descends, it drives the connecting rod 7 to rotate, and then the three clamps 6 rotate to clamp the bearing, and then the internal grinder working wheel 38 enters the inner diameter of the bearing to grind its inner diameter. The working principle of the internal grinder is the existing technology and is not described here. Waste chips will be generated during processing. At this time, the water pump is started and then the clean water in the water tank 10 is discharged to the inside of the first nozzle 8 and the second nozzle 9 through two hoses. The first nozzle 8 The water is sprayed out in atomized form to reduce the chips, so as to prevent the workers from inhaling a large amount of water and affecting their health. The water sprayed from the second nozzle 9 rushes to the grinding wheel 38 to cool the grinding wheel 38. The workbench is provided with a water guide groove. The drained water enters the water guide groove and then returns to the inside of the water tank 10 through the drain pipe 23. The water discharged from the drain pipe 23 will first be filtered by the filter hole 22 of the filter frame 21, and then enters the water tank 10 for secondary use after filtration. Nitrate is placed in the material box 11 through the first opening 12. When the working environment is hot and the water in the water tank 10 needs to be cooled, the second cylinder 15 The output end is retracted and the first rod 18 rotates clockwise. At this time, the first baffle 17 moves along the limit bar 16, and then drives the second rod 19 to rotate. Since the teeth 20 of the two second rods 19 are meshed, the two second rods 19 will rotate relative to each other. Therefore, the two baffles 17 at this time move in the opposite direction along the limit bar 16 to open the second opening 13, and then the nitrate in the material box 11 falls from the second opening 13 into the water tank 10. At the same time, the motor 36 starts to drive the worm 37 to rotate, and then the worm wheel 31 and the rotating shaft 27 start to rotate. The rotating shaft 27 rotates, and the stirring blade 32 and the inclined column 33 rotate. The rotation of the stirring blade 32 is convenient for stirring the nitrate and the water, so that the nitrate quickly dissolves in the water to absorb heat to achieve cooling of the water, and then the sprayed water is cooling water suitable for use in summer. Since the vertical rod 35 is located in the inclined groove 34 and there is a height difference in the inclined groove 34, the rotation of the inclined column 33 will drive the pad 24 and the top block 25 to rise through the vertical rod 35, and then the pad 25 penetrates the filter hole 22 to prevent the filter hole 22 from being blocked, and the spring 26 facilitates the pad 24 to return to the bottom after rising.
