The working principle is as follows: during operation, the twist drill 3-5 is fixed through the claw disc 3-4, then the mounting rail 4-1 is moved transversely, the included angle between the first mounting arm 4-3 and the second mounting arm 4-4 is changed, the angle of the twist drill 3-5 is further determined (the included angle between the first mounting arm 4-3 and the second mounting arm 4-4 relative to the axis of the twist drill 3-5 is changed through the symmetry of the first mounting arm 4-3 and the second mounting arm 4-4 about the axis of the twist drill 3-5, the included angle between the first mounting arm 4-3 and the second mounting arm 4-4 relative to the axis of the twist drill 3-5 is changed through adjusting the included angle between the first mounting arm 4-3 and the second mounting arm 4-4, and further the angle of the grinding disc 2 for grinding the twist drill 3-5 is changed), and meanwhile, as the first feedback rod 7-1 and the second feedback rod 7-2 are respectively in sliding connection with the structures on the first mounting arm 4-3 and the second mounting arm 4-4, the slider 7-1 and the second feedback rod 7-2 are respectively kept in a sliding connection with the first mounting arm 4-3 and the second mounting arm 4-4, and the slider is changed along the transverse sliding state of the sliding shaft 7-5;
then starting a feeding motor 3-1, a first driving motor 3-3 and a second driving motor 5-2, wherein the first driving motor 3-3 drives a claw disc 3-4 to drive a twist drill 3-5 to rotate, so that the grinding disc 2 can uniformly grind the outer diameter of the twist drill 3-5, the feeding motor 3-1 controls the twist drill 3-5 to slowly move rightwards, so that the grinding depth of the grinding disc 2 is increased, the second driving motor 5-2 drives the grinding disc 2 to rotate to grind the twist drill 3-5, meanwhile, the second driving motor 5-2 drives a first gear 5-3 to rotate, the first gear 5-3 drives a second gear 5-6 to rotate, the second gear 5-6 is connected with a reciprocating screw rod 5-4 through threads in the rotating process and reciprocates along the reciprocating screw rod 5-4, so that the grinding disc 2 grinds the twist drill 3-5 along a drill bit oblique angle;
in the process that the grinding disc 2 grinds the twist drill 3-5, the bearings 6-4 and the grinding disc 2 are symmetrical about the twist drill 3-5, and the corresponding bearings 6-4 are tightly attached to the surface of the drill bit of the twist drill 3-5 (meanwhile, the rotary discs 6-4-1 in the bearings 6-4 rotate to reduce the friction force between the bearings and the drill bit of the twist drill 3-5, further, the rotary discs 6-4-1 are independent from each other, so that the damage stress of the bearings 6-4 generated due to different linear velocities of the drill bit is reduced, the bearings 6-4 are further protected, and the service life of the bearings 6-4 is prolonged); as the grinding disc 2 is worn in operation, the distance from the edge of the grinding disc 2 to the drill bit is smaller than the distance from the bearing 6-4 to the drill bit, and the grinding disc 2 has a grinding effect on the drill bit, so that the grinding disc 2 is always tightly attached to the drill bit, further, the drill bit can press the bearing 6-4, so that the bearing 6-4 moves rightwards, the bearing 6-4 moves rightwards to drive the protective shell 6-2 to move rightwards, the protective shell 6-2 pushes the first trigger rod 6-7 to move rightwards relative to the first connecting plate 6-6, the first trigger rod 6-7 pushes the first feedback rod 7-1 to push the second mounting arm 4-4 rightwards, as the second rotating shaft 7-3 is in transverse sliding connection with the sliding rail 7-5 through the sliding block 7-4 and the first feedback rod 7-1 is not changed in inclination angle, the first feedback rod 7-1 drives the second rotating shaft 7-3, the second rotating shaft 7-3 drives the second feedback rod 7-2 to move rightwards, and (refer to figure 14), the second feedback rod 7-2 drives the oil pipe 7-14 to drive the oil pipe 7-7 to move rightwards relative to move towards the U-8, so as to further, the grinding disc 2 to push the integral grinding disc 2 to move towards the upper side of the grinding disc 7-5, and to compensate the grinding disc 5, and the grinding disc 2, so that the grinding disc 2 and the grinding disc 2 moves towards the grinding head and the grinding disc 5, and the grinding head can process the grinding disc 5, and the grinding head, so that the oil pipe 7-5, the grinding head can process the oil pipe 7-5, and the grinding disc 2, so that the oil tank can be more accurately; after the edge position of the grinding disc 2 returns to the original point, the grinding disc 2 grinds a drill bit part which is not ground due to self abrasion, further, when an unnecessary part of the drill bit is ground, the bearing 6-4 is reset under the elastic force of the first elastic telescopic rod 6-5, correspondingly, the first feedback rod 7-1 and the second feedback rod 7-2 are reset, the piston 7-14 moves leftwards, hydraulic oil in a pipeline above the U-shaped oil pipe 7-8 is sucked into a pipeline below the piston, at the moment, under the elastic force of the second elastic telescopic rod 7-12, the sealing plate 7-11 slides towards the oil tank 7-9, the hydraulic oil in the oil tank 7-9 is squeezed into the U-shaped oil pipe 7-8 through the check valve 7-10, the hydraulic oil required to be pumped is further supplemented to be further moved leftwards by the piston 7-14, the hydraulic oil tank 7-9 is prevented from being driven leftwards by the piston 7-14 to move leftwards (note that the elastic force of the second elastic telescopic rod 7-12 squeezes the hydraulic oil in the oil tank 7-9 into the U-shaped oil pipe 7-8, the thrust of the oil tank 7-9, and the elastic telescopic rod 7-5 is smaller than the friction force generated by the elastic telescopic rod which squeezes the integral shell 7-5 and prevents the sliding shell 7-5 of the sliding of the hydraulic oil in the sliding shell 7-5;
and finally, when the feeding motor 3-1 controls the twist drill 3-5 to feed enough displacement to finish machining, the feeding motor 3-1 controls the twist drill 3-5 to retreat, each driving piece stops, and the twist drill 3-5 is taken down.
