The drill rod 5 is pushed to the left by the electric telescopic rod 2 until the head end of the drill rod 5 passes through the circular hole 9 and enters the tapered groove 8. The rotary motor 3 drives the drill rod 5 to rotate, so that the drill bit part of the head end of the drill rod 5 is polished inside the tapered groove 8. The inner wall of the circular hole 9 is smooth and will not hinder the rotation of the drill rod 5. There are multiple tapered grooves 8, and the size of each tapered groove 8 is different, which is convenient for polishing the head end of the drill rod 5 into different sizes according to actual needs. The outer side of the circular hole 9 is covered with a cover plate 11, and the edge of the cover plate 11 is installed with a damping shaft 10, and the sealing box 6 is rotatably connected to the cover plate 11 through the damping shaft 10. Through the mutual cooperation of the damping shaft 10 and the cover plate 11, it is convenient to realize the opening and closing of any circular hole 9. When one of the circular holes 9 is used, the other circular holes 9 are in a closed state, which can avoid dust splashing out of the circular hole 9 when grinding the drill bit.
[0024] The workbench 12 is installed at the bottom end of the sealed box 6, and a bottom support plate 13 is welded to the lower end of the workbench 12, a discharge chute 14 is provided inside the workbench 12, and a waste recovery box 15 is provided below the discharge chute 14, and a support plate 16 is provided below the waste recovery box 15, a fixing plate 17 is welded to the right end of the upper surface of the workbench 12, and a slide groove 18 is provided inside the fixing plate 17, a screw rod 19 is installed inside the slide groove 18, and a servo motor 20 is connected to the rear end of the screw rod 19, and a slider 21 is threadedly connected to the outer side of the screw rod 19, and the servo motor 20 and the slide groove 18 are connected to the slider 21. The mutual cooperation with the screw rod 19 enables the slider 21 to have the function of moving forward and backward. The top end of the slider 21 is fixed to the movable platform 1, so the movable platform 1 can move forward and backward, which is convenient for adjusting the position of the drill rod 5 and inserting the head end of the drill rod 5 into the conical groove 8 of different sizes to grind drill bits of different sizes. One end of the screw rod 19 is rotatably connected to the support plate 16, and the other end of the screw rod 19 is connected to the output shaft of the servo motor 20 through a bearing passing through the rear side of the fixed plate 17. The servo motor 20 provides power for the screw rod 19 to rotate left and right, and the servo motor 20 is controlled by the controller 22.
[0025] Working principle: When in use, firstly, the rear end of the drill rod 5 is effectively fixed by the positioning fixture 4, and then the electric telescopic rod 2 is controlled by the controller 22, and the electric telescopic rod 2 pushes the drill rod 5 to the left until the head end of the drill rod 5 passes through the circular hole 9 and enters the conical groove 8. The rotary motor 3 is started by the controller 22, and the rotary motor 3 drives the drill rod 5 to rotate through the output shaft, so that the head end of the drill rod 5 is polished inside the conical groove 8. There are multiple conical grooves 8 in the device, and the size of each conical groove 8 is different. Therefore, the conical groove 8 of the corresponding size can be selected according to actual needs, so as to facilitate the head of the drill rod 5. The ends are ground into drill bits of different sizes. Since the number of tapered grooves 8 is equal to the number of round holes 9, when one of the round holes 9 is in use, the other round holes 9 are covered by the cover plate 11 and are in a closed state. This can prevent dust generated when grinding the drill bit from splashing out of the round holes 9, and the grinding debris enters the waste recovery box 15 through the discharge chute 14. When replacing tapered grooves 8 of different sizes, the servo motor 20 can be started to rotate the screw rod 19, and the slider 21 can be moved forward or backward until the drill rod 5 is adjusted to a position corresponding to the tapered groove 8, so as to facilitate grinding out drill bits of different sizes.
