Technical Field

[0002] Wear-resistant balls are a type of grinding media used in ball mills to grind materials. Ductile iron grinding balls with a bainitic matrix obtained through heat treatment are called bainitic ductile iron grinding balls; those with a martensitic matrix obtained through heat treatment are called martensitic ductile iron grinding balls. Grinding of wear-resistant balls is generally done manually. Manual grinding allows for good control of grinding time and amount, but it also has significant drawbacks, such as generating a lot of dust that can easily cause respiratory damage to employees. Therefore, we have proposed a feeding device for grinding balls to solve these problems. Summary of the Invention

Detailed Implementation

[0014] The embodiments of this utility model are further described below with reference to the accompanying drawings. Example 1

[0015] like Figures 1 to 3As shown; a feeding device for a grinding ball grinding apparatus includes a grinding wheel 1 and a grinding feeding device 2 that cooperate with each other. The grinding feeding device 2 includes a rotary motor 21, a fixed plate 22, a track ring 23, a rotating plate 24, a positioning rod 26, a U-shaped feeding rail 27, a positioning cylinder 28, a fixed frame 29, a material positioning device 210, a first transmission gear 217, a second transmission gear ring 218, a power gear 219, and a power motor 220. The rotary motor 21, the positioning cylinder 28, and the power motor 220 are also included. The rotating plate 24 is connected to the power rod of the rotary motor 21, and the positioning rod 26 is connected to the piston rod of the positioning cylinder 28. The U-shaped feed rail 27 is connected to the fixed plate 22 via the fixing bracket 29 and cooperates with the positioning rod 26. The power gear 219 is connected to the power rod of the power motor 220 and meshes with the second transmission gear ring 218. The second transmission gear ring 218 is connected to the first transmission gear 217, and the first transmission gear 217 is movably connected to the rotating plate 22. The motor 21 is mounted on the power rod and is connected to the material positioning device 210. Several material positioning devices 210 are mounted on the rotating plate 24 and cooperate with the track ring 23. The track ring 23 is mounted on the fixed plate 22. The track ring 23 has an adjusting angle 25 on the side near the U-shaped feed rail 27. The material positioning device 210 includes a U-shaped wheel 211, a positioning shaft 212, an L-shaped lifting rod 213, a hinge frame 214, a rotating gear 216, and a rotating shaft. Two of the rotating shafts are movably connected to... On the rotating plate 24, the two ends of the rotating shaft are connected to the U-shaped wheel 211 and the rotating gear 216 respectively. The rotating gear 216 meshes with the first transmission gear 217. One end of the two L-shaped lifting rods 213 is connected through the positioning shaft 212 and the other end is connected to the bearing 215. The hinge frame 214 is movably connected to the L-shaped lifting rods 213 and is connected to the rotating plate 24. The L-shaped lifting rods 213 are movably connected to the positioning shaft 212. The surface of the U-shaped wheel 211 is provided with a textured pattern.

[0016] The grinding machine controls the grinding wheels to rise and fall to cooperate with the grinding balls for grinding. This grinding machine is existing technology and will not be described in detail here. Specifically, the rotary motor 21 drives the rotating plate 24 to rotate. The rotation of the rotating plate 24 causes several material positioning devices 210 on it to rotate around the rotary motor 21 at a certain angle. After the bearing 215 of one material positioning device 210 moves to the adjustment angle 25, the weight of the positioning shaft 212 connected to one end of the L-shaped lifting rod 213 causes the positioning shaft 212 to fall, while the bearing 215 on the other end of the L-shaped lifting rod 213 is pressed tightly against the adjustment angle 25. Then, the positioning cylinder 28 controls the positioning rod 26 to rise and fall, so that the grinding balls on the U-shaped feed rail 27 roll into the space between the two U-shaped wheels 211 and the positioning shaft 212. As the rotating plate 24 rotates, the bearing 215 moves out of the adjustment angle 25 area, so that the positioning shaft 212 rises and clamps and positions the grinding balls between the positioning shaft 212 and the positioning shaft 212. Between the two U-shaped wheels 211, the grinding ball is positioned between the grinding wheel 1, the positioning shaft 212, and the two U-shaped wheels 211 for grinding. When the grinding wheel 1 grinds the grinding ball, the grinding ball rolls between the grinding wheel 1, the positioning shaft 212, and the two U-shaped wheels 211, which prevents the grinding ball from flying out during grinding and achieves grinding in the Y-axis direction. Then, the power motor 220 sequentially drives the power gear 219, the second transmission gear ring 218, the first transmission gear 217, the rotating gear 216, the rotating shaft, and the U-shaped wheels 211 to rotate. The U-shaped wheels 211 drive the grinding ball to rotate, so that the grinding ball rolls in the X-axis direction, achieving the purpose of grinding the grinding ball comprehensively and achieving the effect of rapid feeding and positioning grinding of the grinding ball. By opening a textured surface on the U-shaped wheel 211, the friction between the U-shaped wheel 211 and the grinding ball is increased, making it easier for the U-shaped wheel 211 to drive the grinding ball to rotate, while preventing the grinding ball from being driven to rotate by the grinding wheel 1 at a faster speed.
