The rotational power of the motor is transmitted to the tool holder 8 and the grinding head 9. The motor is installed above the rotating rod A, and the output end of the motor is fixedly connected to the top of the rotating rod A. The motor is used to provide rotational power to drive the rotating rod A to rotate. The outer wall of the motor is fixedly connected to the outer shell 7. The outer shell 7 is used to protect the motor and prevent dust and debris from entering. The top of the outer shell 7 is fixedly connected to the mounting plate 6. The mounting plate 6 is used to install and fix the entire grinding device on other equipment or structures. Threaded holes are opened at the four corners of the top of the mounting plate 6. The threaded holes are used to fix the mounting plate 6 in the target position.

[0030] Reference Figures 2-4 The grinding head 9 is equipped with an intermittent cooling assembly, which periodically sprays coolant onto the grinding head 9 to achieve cooling. The assembly includes a storage tank 1 for storing coolant, with an inlet hole at the top for adding coolant to the storage tank 1. The inner wall of the inlet hole is sealed with a sealing plug to prevent coolant leakage from the storage tank 1. A horizontal plate B21 is fixedly connected to the outer wall of the tool holder 8. The horizontal plate B21 supports and mounts components such as the rotating rod B27. The top of the horizontal plate B21 is rotatably connected to the rotating rod B27, which transmits the power of the rotating rod A to the elliptical cam 16. The bottom end of the rotating rod B27 is detachably connected to the elliptical cam 16. The elliptical cam 16 achieves intermittent compression output of coolant by rotating and squeezing the pressure plate 17.

The transmission assembly includes pulley B15, which is fixedly connected to the top of rotor B27. Pulley A14 is fixedly connected to the surface of rotor A. Pulley B15 is larger than pulley A14 to achieve transmission speed reduction, preventing the high rotation speed of the grinding head 9 during grinding, which would cause the elliptical cam 16 to continuously compress without effectively achieving intermittent cooling.

[0033] Reference Figure 2 , Figure 3The edge of the elliptical cam 16 abuts against the end face of the pressure plate 17. The rotation of the elliptical cam 16 periodically squeezes the pressure plate 17. The edge of the piston plate 12 is in sealed contact with the inner wall of the storage tank 1 to ensure that the coolant does not leak when it is squeezed. The other end of the storage tank 1 is fixedly connected to the delivery pipe 2 through the one-way valve 13. The one-way valve 13 is used to prevent the coolant from flowing back and to ensure that the coolant can only flow from the storage tank 1 to the delivery pipe 2.

The detachable component is used to facilitate the replacement of elliptical cams 16 of different sizes to adjust the liquid output.

[0034] Reference Figure 3 - Figure 5 The detachable components include connecting plate A22 and connecting plate B. One side of both connecting plate A22 and connecting plate B is fixedly connected to the end face of the liquid storage tank 1. A sliding groove is provided on the adjacent side of both connecting plate A22 and connecting plate B for sliding of the slider 18 and the pusher block 24. A threaded rod 23 is threadedly connected to the side of connecting plate A22. The threaded rod 23 is used to push the pusher block 24 to move by rotation, thereby adjusting the position of the pressure plate 17. A knob is fixedly connected to one end of the threaded rod 23 for easy manual rotation.

The slider 18 is slidably connected to the inner wall of the slide groove. The surface of the rotating rod B27 is provided with an external thread. The external thread is used to cooperate with the internal thread hole of the elliptical cam 16 to realize the installation and disassembly of the elliptical cam 16. The top of the elliptical cam 16 is provided with an internal thread. The internal thread is used to cooperate with the external thread of the rotating rod B27 to realize the threaded connection between the elliptical cam 16 and the rotating rod B27. The inner wall of the elliptical cam 16 is threadedly connected to the surface of the rotating rod B27.

[0035] Reference Figure 5 The detachable component also includes a limiting ring 25, which is used to limit the axial position of the elliptical cam 16 on the rotating rod B27 to ensure its accurate installation position. The limiting ring 25 is fixedly connected to the surface of the rotating rod B27, and the top surface of the elliptical cam 16 contacts the bottom surface of the limiting ring 25. A nut 26 is threadedly connected to the external thread of the rotating rod B27. The nut 26 is used to fix the elliptical cam 16 on the rotating rod B27 to prevent it from loosening. The top of the nut 26 contacts the bottom of the elliptical cam 16.

[0036] Working principle: When the motor is started, the motor's output shaft drives the rotating rod A to rotate, which in turn drives the tool holder 8 to rotate. The tool holder 8 then drives the grinding head 9 to rotate, using the rotating grinding head 9 to grind the workpiece. Simultaneously, the rotation of rotating rod A drives rotating rod B27 via belt transmission. Rotating rod B27 drives elliptical cam 16 to rotate, which reciprocates by pressing against pressure plate 17. Pressure plate 17 drives a movable rod to compress spring 19, which in turn drives piston plate 12 to compress the coolant inside storage tank 1. The coolant flows from the infusion pipe 2 through one-way valve 13 to nozzle 10, which sprays the coolant onto the rotating grinding head 9. Different sizes of elliptical cams 16 can be used to achieve different output volumes. To disassemble elliptical cam 16, a knob is turned, which drives threaded rod 23 to rotate. 23 pushes the push block 24 to move in the groove A opened in the connecting plate A22. The push block 24 squeezes the slider 18, thereby driving the slider 18 and the pressure plate 17 to move, thus leaving a distance between the elliptical cam 16 and the pressure plate 17. Then, the nut 26 is removed from the bottom end of the rotating rod B27. Then, the elliptical cam 16 is rotated in the opposite direction on the outer surface of the rotating rod B27 to separate the elliptical cam 16 from the rotating rod B27. Replace the elliptical cam 16 with a different size, provided that the internal thread hole of the elliptical cam 16 is the same size. Install the elliptical cam 16 of different sizes on the external thread of the rotating rod B27. The elliptical cam 16 is limited by the set limit ring 25. Install the nut 26 on the external thread of the rotating rod B27. Then, rotate the threaded rod 23 in the opposite direction until the pressure plate 17 contacts the edge of the replaced elliptical cam 16.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
