Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments.

[0037] like Figure 1-4 As shown, a grinding and maintenance device for a rod milling cutter proposed in this embodiment includes a base plate 1 and also includes:

[0038] The electric slide 3 is installed on one side of the top of the bottom plate 1, and a transmission motor 2 is installed on one side of the electric slide 3;

[0039] A manual slide 4 is installed at the moving end of the electric slide 3, and a mounting platform 5 is installed at the moving end of the manual slide 4;

[0040] The guide structure 6 is detachably mounted on one side of the mounting platform 5, wherein the guide structure 6 comprises a fixed frame 601 fixed on one side of the mounting platform 5, a movable seat 605 sliding inside the fixed frame 601, a fixed component disposed on the top of the movable seat 605, and a guide tooth 602 disposed on the top of the fixed component;

[0041] The air bearing 7 is mounted on the top of the mounting platform 5, and the moving end of the air bearing 7 is mounted with a rod milling cutter fixture 14;

[0042] A support plate 8 is fixed to the other side of the top of the bottom plate 1, and a connecting shell 10 is provided on one side of the support plate 8;

[0043] A spindle motor 11 is installed inside the connecting shell 10, and a protective cover 12 is installed on one side of the connecting shell 10. A grinding wheel 13 is detachably installed on the rotating end of the connecting shell 10;

[0044] The flip structure 9 is arranged on one side of the support plate 8 and is used to adjust the angle at which the grinding wheel 13 is placed.

[0045] like Figure 1 , Figure 2 and Figure 4 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the fixing component includes a lifting rod 604 inserted at the top of the moving seat 605, a rotating shell 603 sleeved on the outside of the lifting rod 604 and rotatably connected to the moving seat 605, and a cam rod 606 installed at the bottom end of the moving seat 605. The outer wall of the lifting rod 604 is provided with an external thread, and the interior of the rotating shell 603 is provided with an internal thread that cooperates with the external thread. By pulling the moving seat 605 to slide inside the fixed frame 601, the position of the guide tooth 602 is adjusted. By rotating the rotating shell 603, the rotating shell 603 pushes the lifting rod 604 to move through the thread, and the height of the guide tooth 602 is adjusted so that the guide tooth 602 is inserted into the spiral knife groove of the rod milling cutter. When the air bearing 7 is pushed to telescopically move the position of the rod milling cutter, the guide tooth 602 slides inside the knife groove to limit the moving path of the rod milling cutter, so that the rod milling cutter rotates slowly during the movement. At the same time, the spiral blade always keeps in contact with the grinding wheel 13 to ensure the grinding accuracy of the device.

[0046] like Figure 1 , Figure 2 and Figure 3 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the flip structure 9 includes an electric telescopic rod 901 installed on one side of the support plate 8, a guide shell 902 arranged at the top of the electric telescopic rod 901 and connected to the support plate 8, a moving plate 903 inserted in the guide shell 902 and connected to the moving end of the electric telescopic rod 901, and a transmission assembly installed at the top of the moving plate 903, the transmission assembly includes a rack 906 fixed at the top of the moving plate 903, a rotating shaft 905 inserted at the top of the support plate 8 and in contact with the connecting shell 10, and a rotating shaft 906 sleeved on the rotating shaft 9 05 and the gear 904 meshing with the rack 906, a sliding structure is formed between the movable plate 903 and the rack 906, the rotating shaft 905 passes through the supporting plate 8 and is connected to the connecting shell 10, and by starting the electric telescopic rod 901 to extend, the electric telescopic rod 901 pushes the movable plate 903 to slide inside the guide shell 902, and at the same time, the movable plate 903 drives the rack 906 to move, so that the rack 906 pushes the rotating shaft 905 and the gear 904 to rotate through the meshing of the teeth, and then the gear 904 drives the spindle motor 11 and the connecting shell 10 to flip through the rotating shaft 905 to adjust the inclination angle of the grinding wheel 13.

[0047] Specifically, when the present grinding and maintenance device for the rod milling cutter is used: the rod milling cutter is inserted into the air bearing 7, and the position of the rod milling cutter is fixed by using the rod milling cutter fixture 14. At the same time, the air bearing 7 enables the rod milling cutter to move forward and backward after being fixed, or to rotate and adjust the position. Then, the electric slide 3 and the manual slide 4 are used to adjust the position of the rod milling cutter so that the rod milling cutter contacts the grinding wheel 13. The inclination of the grinding wheel 13 is adjusted by the flip structure 9. The spindle motor 11 is started to drive the grinding wheel 13 to rotate, so that the grinding wheel 13 rotates at a high speed to grind the rod milling cutter. The guide structure 6 is inserted into the groove of the rod milling cutter to guide the rotation of the rod milling cutter so that the cutting edge of the rod milling cutter is always in contact with the grinding wheel 13 during the movement of the rod milling cutter.

[0048] By pulling the movable seat 605 to slide inside the fixed frame 601, the position of the guide tooth 602 is adjusted, and by rotating the rotating shell 603, the rotating shell 603 pushes the lifting rod 604 to move through the thread, and the height of the guide tooth 602 is adjusted, so that the guide tooth 602 is inserted into the spiral cutter groove of the rod milling cutter. When the air bearing 7 is pushed to telescopically move the position of the rod milling cutter, the guide tooth 602 slides inside the cutter groove to limit the moving path of the rod milling cutter, so that the rod milling cutter rotates slowly during the movement process, and at the same time, the spiral blade is always kept in contact with the grinding wheel 13 to ensure the grinding accuracy of the device;

[0049] By starting the electric telescopic rod 901 to extend, the electric telescopic rod 901 pushes the movable plate 903 to slide inside the guide shell 902, and at the same time the movable plate 903 drives the rack 906 to move, so that the rack 906 drives the rotating shaft 905 and the gear 904 to rotate through the meshing of the teeth, and then the gear 904 drives the spindle motor 11 and the connecting shell 10 to flip through the rotating shaft 905 to adjust the inclination angle of the grinding wheel 13.

[0050] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the invention are included in the scope of the claims of the present invention.
