Description

Technical Field

[0001] The present invention relates to the technical field of grinding ball production, and particularly to a casting pouring device for grinding ball production. Background Art

[0002] Grinding balls are made from materials such as bauxite, roller rod powder, industrial alumina powder, and high-temperature calcined alpha alumina powder through processes such as batching, grinding, powder making, forming, drying, and firing. They are mainly used as grinding media and are widely used ball stones. According to different alumina contents, they can be divided into medium alumina balls, medium-high alumina balls, and high alumina balls. Generally, we classify those with 60%-65% alumina content as medium alumina balls, those with 75%-80% alumina content as medium-high alumina balls, and those with more than 90% alumina content as high alumina balls.

[0003] A casting pouring device for grinding ball production proposed by Chinese Publication No. CN218693837U includes two support plates. A lifting plate is fixedly installed between the two support plates. Rotating shafts are rotatably installed on one side of the two support plates close to each other. The same pouring bucket is fixedly installed at one end of the two rotating shafts close to each other. Connecting shells are fixedly installed on one side of the two support plates away from each other, and one end of the rotating shaft is rotatably installed on the inner wall of the connecting shell. A moving seat is slidably installed in the connecting shell. A driving seat is fixedly installed at the bottom of the moving seat, and a transmission mechanism is provided between the driving seat and the rotating shaft. The design of the present utility model is reasonable. By the movement of the threaded rod to drive the two rotating shafts, the pouring bucket can be driven to rotate smoothly, which can improve the stability of the pouring bucket, so that the pouring liquid in the pouring bucket can be poured out smoothly, reducing the situation of spilling.

[0004] The above-mentioned technical solution of the casting pouring device does not have a supporting moving mechanism, so that the casting pouring device can only carry out casting pouring at one station, and it cannot pour at multiple different stations, with low flexibility, resulting in relatively low work efficiency of the casting pouring for grinding ball production. Summary of the Invention

[0005] The purpose of the present invention is to solve the problem that the existing casting pouring device can only carry out casting pouring at one station and cannot pour at multiple different stations, and to propose a casting pouring device for grinding ball production.

[0006] To achieve the above purpose, the present invention adopts the following technical solutions:

[0013] Preferably, both ends of the second traction rod are respectively pin-connected to the sliding sleeve and the first slider, and both ends of the third traction rod are respectively pin-connected to the folding plate and the sliding sleeve.

A connecting rod extending and penetrating to a position below the bracket is fixedly connected to the nut. A driven rack is fixedly connected to the connecting rod. A driving gear meshingly connected to the driven rack is fixedly sleeved on the rotating shaft.

[0016] Preferably, a rotating plate is fixedly connected to the outer end of the worm. A guiding through hole for movably sleeving the connecting rod is formed in the bracket.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] 1. In the present invention, the electric push rod drives the second slider to move through the fourth traction rod, so that the clamping plate can drive the sliding sleeve to move vertically upward on the sliding rod through the third traction rod. The sliding sleeve drives the first slider to move horizontally through the second traction rod.

The sliding sleeve drives the first slider to move horizontally through the second traction rod. The first slider drives the driving frame to move vertically downward through the first traction rod, so as to facilitate operators of different heights to deflect the pouring cylinder and adapt to workstations at different height positions. The worm drives the ball screw to rotate through the worm gear. The ball screw drives the connecting rod to move vertically downward through the nut. The connecting rod drives the driving gear to drive the pouring cylinder to deflect through the rotating shaft. By utilizing the characteristic that the meshing transmission between the worm and the worm gear is unidirectional, the worm gear will not drive the ball screw to rotate without external force, thereby playing a self-locking role, so that the pouring barrel will not rotate reversely due to the action of gravity, which helps to improve the stability of the pouring barrel.

Specific embodiments

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0027] Refer to Figures 1-4 , a casting pouring device for grinding ball production, including an electric slide rail 1. The specific model and specification of the electric slide rail 1 need to be selected according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in the field, so it will not be elaborated. A drive box 2 is fixedly connected to the electric slide rail 1. A first chute 3 is opened on the drive box 2. A first slider 4 is horizontally slidably sleeved in the first chute 3. Through the guiding and limiting action of the first chute 3, the first slider 4 can only perform horizontal movement in the first chute 3;

[0028] The first slider 4 is pin-connected with a first traction rod 5. The first traction rod 5 is pin-connected with a drive frame 6. A guide rod 7 is fixedly connected to the drive frame 6. A guide block 8 slidably connected to the guide rod 7 is fixedly connected to the drive box 2. A first moving through hole for slidably sleeving the guide rod 7 is opened on the guide block 8. Through the guiding and limiting action of the first moving through hole, the guide block 8 can only perform vertical movement on the guide rod 7, so as to ensure the stability of the drive frame 6 during lifting;

[0029] A rotating shaft 9 is rotatably mounted on the driving frame 6 through bearings. The inner end of the rotating shaft 9 is fixedly connected with a pouring cylinder 10. The rotating shaft 9 is symmetrically arranged horizontally on both sides of the pouring cylinder 10;

[0030] A lifting mechanism for driving the first sliders 4 to move towards each other is arranged in the driving box 2. Through the lifting mechanism, the first traction rod 5 can be driven by the first sliders 4 to deflect. Due to the position difference generated by the deflection of the first traction rod 5, the driving frame 6 can be driven to move vertically downward, enabling the casting pouring device for grinding ball production to adapt to workstations at different heights and helping to improve the applicability of the casting pouring device for grinding ball production;

[0031] Further explanation: The lifting mechanism includes a sliding rod 11 fixedly connected to the driving box 2. A sliding sleeve 12 is slidably sleeved on the sliding rod 11. Due to the arrangement of the sliding rod 11, the sliding sleeve 12 can only move vertically on the sliding rod 11;

[0032] A second traction rod 13 is connected between the sliding sleeve 12 and the first slider 4. A receiving groove 14 is formed on the driving box 2. A folding plate 15 is rotatably mounted on the receiving groove 14. It should be noted that: The middle position of the folding plate 15 is rotatably mounted on the receiving groove 14 and rotates and deflects with the middle point of the folding plate 15 as the base point. A third traction rod 16 is pin-connected between the folding plate 15 and the sliding sleeve 12;

[0033] An electric push rod 17 is fixedly installed in the driving box 2. The specific model and specification of the electric push rod 17 need to be selected according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in the field, so it will not be elaborated here. A second moving through hole for movably sleeving the output end of the electric push rod 17 is formed on the driving box 2, which can provide a moving space for the electric push rod 17;

[0034] A second sliding groove 18 is formed at the outer end of the folding plate 15. A second slider 19 is horizontally slidably sleeved in the second sliding groove 18, which can provide a moving space for the movement of the second slider 19. A fourth traction rod 20 is pin-connected between the electric push rod 17 and the second slider 19, and the second sliding groove 18 and the second slider 19 can provide a moving space for the deflection movement of the fourth traction rod 20;

[0035] A driving mechanism for driving the pouring cylinder 10 to rotate is arranged in the driving frame 6. Through the driving mechanism, the pouring cylinder 10 can be deflected and tilted. By rotating the rotating plate, the pouring cylinder 10 can be deflected, which helps to facilitate the operation of the operator;

[0036] Further explanation: The driving mechanism includes an installation cavity 21 formed on the driving frame 6. The installation cavity 21 is horizontally rotatably installed with a worm 22 through a bearing. The outer end of the worm 22 is fixedly connected with a rotating plate. The inner wall of the installation cavity 21 is integrally connected with a support 23. The support 23 is rotatably installed with a ball screw 24 through a bearing. A worm gear 25 meshed with the worm 22 is fixedly sleeved on the ball screw 24. A nut 26 is installed on the ball screw 24 in a matching manner. Because the meshing transmission between the worm 22 and the worm gear 25 is unidirectional, the worm gear 25 will not drive the ball screw 24 to rotate without external force, thus playing a self-locking role, so that the nut 26 will not be affected by gravity and shift in the vertical direction, which helps to improve the stability of the driving mechanism;

[0037] The nut 26 is fixedly connected with a connecting rod 27 extending and passing through the lower position of the support 23. The support 23 is provided with a guiding through hole for movably sleeving the connecting rod 27. The guiding through hole can provide a moving space for the connecting rod 27 and guide and limit the vertical movement of the connecting rod 27. The connecting rod 27 is fixedly connected with a driven rack 28. A driving gear 29 meshed with the driven rack 28 is fixedly sleeved on the rotating shaft 9.

[0038] The functional principle of the present invention can be described through the following operation methods:

[0039] The electric slide rail 1 can drive the driving box 2 to move horizontally, so that the pouring cylinder 10 moves to the position above the designated station. The electric push rod 17 is started to drive the fourth traction rod 20 to deflect. The fourth traction rod 20 drives the second slider 19 to move in the second chute 18, so that the opening and closing plate 15 deflects downward. The opening and closing plate 15 drives the third traction rod 16 to deflect. The third traction rod 16 drives the sliding sleeve 12 to move vertically upward on the sliding rod 11. The sliding sleeve 12 drives the second traction rod 13 to deflect. The second traction rod 13 drives the first slider 4 to move horizontally in the first chute 3. The first slider 4 drives the first traction rod 5 to deflect. The first traction rod 5 drives the driving frame 6 to move vertically downward. The driving frame 6 drives the guiding rod 7 to move vertically downward on the guiding block 8;

[0040] The worm 22 is rotated. The worm 22 drives the worm gear 25 to rotate. The worm gear 25 drives the ball screw 24 to rotate. The ball screw 24 drives the nut 26 to move vertically downward. The nut 26 drives the connecting rod 27 to move vertically downward. The connecting rod 27 drives the driven rack 28 to move vertically downward. The driven rack 28 drives the driving gear 29 to rotate. The driving gear 29 drives the rotating shaft 9 to rotate. The rotating shaft 9 drives the pouring cylinder 10 to deflect, so as to carry out the casting and pouring operation.

[0041] As described above, it is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
