Description

Technical Field

[0001] The utility model relates to the technical field of steel ball production, in particular to a feeding device for detecting the diameter of wear-resistant steel balls. Background Art

[0002] Wear-resistant steel balls are a kind of crushing medium used in ball mills to crush materials in the mill. During the production process of wear-resistant steel balls, in order to ensure the consistency of the wear-resistant steel balls, it is necessary to conduct random inspections on the diameter of the wear-resistant steel balls.

[0003] Most steel ball detection devices use a steel ball placement ring, a measuring plate, an electric push rod and a distance sensor. The steel ball is placed on the placement ring, and the electric push rod drives the two measuring plates to move closer to each other to clamp the steel ball. The distance sensor detects the distance between the two measuring plates, which is the diameter of the steel ball. However, after the detection is completed, the steel ball needs to be removed from the steel ball placement ring, making it difficult to quickly determine whether the installation of the steel ball is within the error range and feed it separately. Utility Model Content

[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1:

[0026] like Figure 1-4 As shown, a feeding device for detecting the diameter of a wear-resistant steel ball comprises two support plates 1 and a connecting rod 2 fixedly arranged between the two support plates 1, an electric push rod 3 is fixedly arranged on the outside of the two support plates 1, the telescopic ends of the two electric push rods 3 penetrate into the inside of the support plates 1 and are provided with a measuring plate 4, a distance sensor 10 is embedded in the inside of one of the measuring plates 4, a controller 6 is provided on the outside of one of the support plates 1, the distance sensor 10 and the electric push rod 3 are electrically connected to the controller 6 respectively, a rotating plate 8 is rotatably provided between the two support plates 1, two supporting rods 9 for supporting steel balls are symmetrically provided on the upper end of the rotating plate 8, and a constraint component for keeping the rotating plate 8 in a horizontal state is provided on the inside of the two support plates 1 respectively;

[0027] The constraint assembly includes a fixed plate 11 fixed on the inner side of the support plate 1 and a V-shaped rod 13 rotatably arranged at the lower end of the fixed plate 11. A torsion spring is provided at the rotating connection of the V-shaped rod 13. The upper surface height of the V-shaped rod 13 is lower than the lower surface height of the measuring plate 4. An extrusion rod 14 is fixed to the lower end of the V-shaped rod 13. A rotating wheel 15 is rotatably provided on the upper surface of the other end of the V-shaped rod 13 to cooperate with the measuring plate 4. A pressure block 12 is fixed to the upper end of the rotating plate 8 to cooperate with the extrusion rod 14. When in use, the electric push rod 3 is first controlled to extend to drive the measuring plates 4 to move closer to each other, and then the steel balls are placed on the two supporting rods 9. The electric push rod 3 continues to move so that the measuring plate 4 is close to the surface of the steel ball. Then the distance sensor 10 feeds back the measurement results to the controller 6, and the controller 6 analyzes and processes the detection results Then the electric push rod 3 is controlled to retract (if the test result is within the error range, one of the electric push rods 3 is started to retract; if the test result is not within the error range, the other electric push rod 3 is started to retract). The contraction of the electric push rod 3 drives the measuring plate 4 to move. The gradual movement of the measuring plate 4 will squeeze the rotating wheel 15, causing the V-shaped rod 13 to deflect. The deflection of the V-shaped rod 13 drives the extrusion rod 14 to revolve, causing the extrusion rod 14 to squeeze the pressure block 12, thereby causing the rotating plate 8 to deflect to one side. The deflection of the rotating plate 8 drives the supporting rod 9 to deflect and tilt, thereby causing the steel ball on the supporting rod 9 to slide along the supporting rod 9. That is, by controlling different electric push rods 3 to retract, the rotating plate 8 is controlled to deflect to different sides, thereby causing the steel ball to slide to different sides along the supporting rod 9, thereby achieving the effect of separating the steel balls according to qualified and unqualified materials.

[0028] Furthermore, baffles 5 are fixedly provided on opposite sides of the two measuring plates 4. When the two measuring plates 4 approach each other, the two baffles 5 are respectively blocked on both sides of the upper end of the supporting rod 9, effectively preventing the steel ball placed on the supporting rod 9 from sliding off.

[0029] Furthermore, a collection frame 7 is provided between the two support plates 1 to match the two ends of the supporting rod 9, so that the steel balls sliding along the supporting rod 9 fall into the collection frame 7, thereby achieving the effect of collecting the steel balls.

[0030] Example 2:

[0031] like Figure 1-4As shown, a through slot 18 is provided through the middle of the rotating plate 8, and a moving block 17 that slides with the through slot 18 is fixed at the lower ends of the two supporting rods 9. A two-way screw rod 16 is rotatably provided inside the through slot 18, and the two moving blocks 17 are respectively threadedly connected to the two-way screw rod 16. The two ends of the two-way screw rod 16 are respectively movable through the outside of the support plate 1 and are provided with an operating handle. A travel groove that cooperates with the two-way screw rod 16 is provided on the surface of the two support plates 1. When in use, the two-way screw rod 16 is driven to rotate by rotating the operating handle, and the rotation of the two-way screw rod 16 drives the two moving blocks 17 to move, and the movement of the two moving blocks 17 drives the supporting rod 9 to move, thereby achieving the effect of adjusting the distance between the two supporting rods 9, which is convenient for steel balls of different diameters to be placed on the two supporting rods 9.

[0032] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
