Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of aluminum block production equipment, specifically to a torsion pull base with multi-point leveling function. Background Technology
[0002] After the molten aluminum is electrolytically purified and cooled in a crucible, a 50mm-60mm diameter extraction hole is drilled into the aluminum block. This hole is used to pull out the aluminum block. The traditional method is to use a crane hook to lift a reaming tool, then manually insert the reaming tool into the extraction hole, and then the crane lifts the block to pull it out.
[0003] Torsion-pulling bases typically employ a rigid connection structure design, and their assembly with the equipment frame is mostly fixed, possessing only vertical lifting and lowering drive capabilities, lacking active adjustment functions for horizontal or inclined directions. In actual industrial production scenarios, the factors causing slight deviations between the torsion-pulling base and the crucible during descent are diverse and unavoidable: First, after long-term operation, the frame, guide rails, and other supporting structures are prone to minor deformation or wear, compromising the original assembly precision and causing the torsion-pulling base's lifting trajectory to deviate from the preset vertical direction; Second, the crucible undergoes thermal expansion and contraction under high-temperature conditions, potentially causing slight offsets in its own axis, and it is also difficult to completely eliminate installation errors below the millimeter level during crucible installation and positioning; Third, limitations in the torsion-pulling base's own machining precision, such as the fit clearance between the base body and the lifting drive mechanism, and coaxiality deviations in the torsion-pulling component mounting holes, all amplify positional deviations during descent.
[0004] When the torsion base descends and there is a slight deviation from the crucible as described above, the existing rigid torsion base structure cannot adaptively adjust to this deviation, making it difficult for the torsion assembly to smoothly enter the crucible. A more prominent problem is that the deviation will cause direct hard friction between the torsion base or torsion assembly and the inner wall of the crucible. Utility Model Content
[0005] To address the aforementioned issues, this utility model provides a torsion-pulling base with multi-point leveling function. When the torsion-pulling base descends and there is a slight deviation from the crucible, the adjustment mechanism enables the torsion-pulling component to smoothly enter the crucible by tilting, thus avoiding hard friction between the torsion-pulling base and the inner wall of the crucible.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a torsion base with multi-point leveling function, comprising a mounting plate for mounting a tie rod mechanism, a positioning frame disposed below the mounting plate, a support plate disposed inside the positioning frame, an adjustment mechanism disposed between the support plate and the mounting plate, and a guide component extending below the positioning frame disposed on the lower surface of the mounting plate.
[0007] As a further improvement to the above technical solution: The adjustment mechanism includes a fixed plate, an adjusting plate, and a connecting screw, with an adjusting spring provided between the fixed plate and the adjusting plate.
[0008] The fixed plate is provided with a positioning shaft sleeved in the adjusting spring, and a positioning screw is slidably installed in the adjusting plate. A limiting plate located below the adjusting plate is provided on the side wall of the positioning screw, and a fitting clearance is reserved between the positioning shaft and the positioning screw.
[0009] The lower part of the positioning screw is provided with a clearance chamber, and the upper end of the positioning shaft is provided with a conical head that cooperates with the clearance chamber.
[0010] The number of connecting screws is multiple and they are evenly distributed along the circumference of the fixed disk.
[0011] The number of adjustment mechanisms is multiple and they are evenly distributed along the circumference of the mounting plate.
[0012] The guide assembly includes multiple guide plates evenly distributed along the circumference of the mounting plate, with supporting ribs provided between adjacent guide plates.
[0013] The outer end face of the guide plate is provided with a positioning surface, and the lower end is provided with an inwardly inclined guide surface.
[0014] The beneficial effects of this utility model embodiment are as follows: The torsion base with multi-point leveling function includes a mounting plate for mounting the tie rod mechanism. A positioning frame is provided below the mounting plate, and a support plate is provided inside the positioning frame. An adjustment mechanism is provided between the support plate and the mounting plate. The adjustment structure can ensure that the crucible and the torsion base can smoothly enter the crucible by tilting the torsion base when there is a slight deviation between them, thus avoiding damage to the equipment caused by hard friction between the two. The guide component can ensure that the torsion base and the crucible are concentrically distributed, which facilitates the docking of the tie rod mechanism with the lifting hole.

[0017] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.
[0018] like Figure 1-5 As shown, the torsion base with multi-point leveling function in this embodiment includes a mounting plate 1 for mounting a tie rod mechanism. A positioning frame 2 that abuts against the upper end of the crucible is provided below the mounting plate 1. A support plate 3 is provided on the inner side of the positioning frame 2. An adjustment mechanism is provided between the support plate 3 and the mounting plate 1. A guide component extending to the lower part of the positioning frame 2 is provided on the lower surface of the mounting plate 1.
[0019] The adjustment mechanism includes a fixed plate 4, an adjusting plate 5, and a connecting screw 6. An adjusting spring 7 is provided between the fixed plate 4 and the adjusting plate 5. A positioning shaft 8 is provided on the fixed plate 4 and sleeved inside the adjusting spring 7. A positioning screw 9 is slidably installed inside the adjusting plate 5. A limiting plate 10 located below the adjusting plate 5 is provided on the side wall of the positioning screw 9. A fitting clearance is reserved between the positioning shaft 8 and the positioning screw 9. The adjusting spring 7 can provide deflection avoidance for the torsion base when there is a slight deviation between the torsion base and the top of the crucible. The design of multiple adjustment mechanisms can ensure that the torsion base can be tilted in any direction, ensuring that the torsion assembly can be smoothly inserted into the crucible. At the same time, it avoids the damage to the torsion base caused by the interaction between the inner wall of the crucible and the torsion base in the case of rigid connection, especially the damage to the pull rod mechanism. At the same time, in the initial state, the adjusting spring can be used to adjust the lower surfaces of multiple adjustment mechanisms to the same horizontal plane, ensuring that the lower end surface of the torsion base remains flush.
[0020] The lower part of the positioning screw 9 is provided with a relief chamber 11, and the upper end of the positioning shaft 8 is provided with a conical head 12 that cooperates with the relief chamber 11. The diameter of the conical head 12 is distributed in a stepped manner. When the aluminum block is pulled out, the conical head can provide guidance when the positioning screw 9 and the positioning shaft 8 in the torsion base are in contact. After the positioning screw 9 and the positioning shaft 8 come into contact, the pressure on the torsion base when the aluminum block is pulled out can be transmitted to the support plate 3, reducing the pressure on the spring.
[0021] The number of connecting screws 6 is multiple and they are evenly distributed along the circumference of the fixed plate 4 to improve the connection stability between the fixed plate 4 and the adjusting plate 5.
[0022] The number of adjustment mechanisms is multiple and they are evenly distributed along the circumference of the mounting plate 1. In this embodiment, four are preferred, which can provide deflection clearance for the torsion base from multiple directions.
[0023] The guide assembly includes multiple guide plates 13 evenly distributed along the circumference of the mounting plate 1, and a support rib 14 is provided between two adjacent guide plates 13.
[0024] The guide plate 13 has a positioning surface 15 on its outer end face and an inwardly inclined guide surface 16 on its lower end. The rotation diameter of the guide surface 16 is smaller than the inner wall diameter of the crucible body, which facilitates the insertion of the torsion base into the crucible. The rotation diameter of the positioning surface 15 is equal to the inner wall diameter of the crucible body, thus providing final positioning.
[0025] In use, in the initial state, the lower end face of the torsion base is adjusted to be in the same horizontal plane using the adjusting spring in the adjusting mechanism to ensure that the lower surface of the torsion base is flat. When the aluminum block needs to be pulled out, the positioning frame 2 descends and abuts against the top of the crucible. During this process, the guide plate 13 enters the crucible. At this time, the adjusting mechanism can provide a buffer against the positional deviation of the torsion base and avoid slight misalignment between the torsion base and the crucible, which would cause hard friction between the torsion base and the crucible. This ensures that the torsion base can enter the crucible smoothly. Multiple guide plates 13 can ensure that the crucible and the torsion base are in a concentric state. After the positioning frame 2 abuts against the crucible, the pull rod mechanism operates. The pull rod extends down into the lifting hole on the aluminum block. When the pull rod pulls the aluminum block upward, it will apply downward pressure to the mounting plate. At this time, the positioning shaft 8 and the positioning screw 9 contact, transmitting the pressure to the support plate 3 to prevent the adjusting spring from being damaged by force.
