Description

Technical Field

[0001] This utility model relates to the field of motor core processing technology, and in particular to a mechanical lifting device. Background Technology

[0002] During the installation of an electric motor, especially in the stator and rotor, the installation of the iron core is particularly important. Generally, the iron core should first be raised to a suitable position to facilitate the operator's inspection, replacement or cleaning work.

[0003] Chinese patent CN210117201U discloses a mechanical lifting device with a stabilizing mechanism, including a lifting device body. The lifting device body includes a cuboid base and an electric cylinder fixed on the base. The electric cylinder is bolted to the center of the upper surface of the base, and the lifting cylinder shaft of the electric cylinder is vertically upward. In this invention, the support plate connects four guide columns for guidance and the lifting cylinder shaft into one unit. In this way, the support plate plays a balancing support role. The integrated guide columns can effectively improve the overall stability and further prevent the tilting of a single guide column. The auxiliary upright and guide hole play a secondary guiding role. At the same time, the guiding movement between the auxiliary upright and the base stabilizes the actual posture of the support plate, and the support plate also provides auxiliary stabilization for the guide columns. Under the dual stabilizing effect, the guide columns play a good stabilizing role in the actual lifting of the support plate.

[0004] However, this technical solution has a problem with the iron core on the support plate shifting position during lifting because there is no positioning mechanism on the support plate. This results in insufficient stability and requires repositioning, which is cumbersome and inconvenient to use, and does not meet the actual needs. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a mechanical lifting device. By installing a rotating mechanism on the workbench, the iron core can be directly placed on the rotating mechanism, and the iron core can be lifted and lowered through the lifting structure without deviation or shaking. The iron core can also be rotated to check for damage, thus solving the problem of deviation that easily occurs in existing products.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A mechanical lifting device includes: a base, a lifting mechanism disposed on the base for driving the iron core to rise and fall, a worktable disposed on the top of the lifting mechanism, and a rotating mechanism disposed on the worktable for driving the iron core to rotate.

[0008] Preferably, the lifting mechanism includes: a plurality of guide columns disposed between the base and the worktable, and a lifting component disposed in the middle of the base.

[0009] Preferably, the lifting component includes: a driving component fixedly connected to the base, a lead screw disposed at the output end of the driving component, and a fixing block disposed between the lead screw and the worktable.

[0010] Preferably, the guide post is slidably connected to the guide sleeve on the base.

[0011] Preferably, the guide post is fixedly connected to the fixing sleeve at the bottom of the worktable.

[0012] Preferably, the rotating mechanism includes: a receiving seat disposed on the upper surface of the worktable and a plurality of rolling elements disposed on the receiving seat.

[0013] Preferably, the iron core is placed between the two rolling elements and does not interfere with the upper surface of the receiving seat.

[0014] Preferably, the height of the base is adapted to the height of the guide post.

[0015] Preferably, the length of the rolling element is adapted to the thickness of the iron core.

[0016] Preferably, the length of the lead screw is adapted to the length of the guide post.

[0017] The beneficial effects of this utility model are as follows:

[0018] (1) This utility model uses a lifting mechanism to drive the rotating mechanism to move up and down, so that the height of the iron core can be adjusted and the iron core can be checked for damage by rotation, which can ensure the normal progress of the next process of the iron core and ensure work efficiency.

[0019] (2) By placing the iron core on two rolling elements, the present invention can form two-point support. Since the iron core is curved, the iron core is stable enough and will not shift to the sides or sway back and forth, thus improving the stability of the iron core.

[0020] (3) This utility model drives the iron core to move up and down through the ball screw mechanism, which has high transmission efficiency, fast response speed, and can quickly adjust the up and down position, thereby ensuring work efficiency. Moreover, its structure is simple, easy to disassemble and assemble, and has low cost of use.

[0021] In summary, this utility model has the advantages of good stability, high working efficiency, long service life, simple structure and convenient assembly and disassembly. Attached Figure Description

[0028] Example

[0029] like Figures 1-4As shown, this embodiment provides a mechanical lifting device, generally applicable to stator cores, including: a base 1, a lifting mechanism 2 mounted on the base 1 for lifting the core 100, a worktable 3 mounted on the top of the lifting mechanism 2, and a rotating mechanism 4 mounted on the worktable 3 for rotating the core 100. The rotating mechanism 4 can both support the core 100 to prevent it from shifting and drive the core 100 to rotate under external force, ensuring versatility of function. Combined with the lifting function of the lifting mechanism 2, the height of the core 100 can be adjusted, maximizing the normal progress of the next process of the core 100 and ensuring work efficiency.

[0030] The lifting mechanism 2 includes: a plurality of guide columns 21 disposed between the base 1 and the worktable 3, and a lifting component 22 disposed in the middle of the base 1, wherein the lifting component 22 drives the guide columns 21 to move up and down.

[0031] Meanwhile, the lifting component 22 includes: a driving component 221 fixedly connected to the base 1, a lead screw 222 disposed at the output end of the driving component 221, and a fixing block 223 disposed between the lead screw 222 and the worktable 3. The driving component 221 provides power to drive the lead screw 222 to rotate, thereby driving the fixing block 223 to move up and down, so that the iron core 100 can move up and down. Its structure is simple, which can save manpower and material resources, reduce the cost of use, and thus improve work efficiency.

[0032] In this embodiment, the guide post 21 is slidably connected to the guide sleeve on the base 1, that is, the guide post 21 can move freely up and down on the guide sleeve, thereby ensuring the lifting and lowering of the iron core 100. The whole process is simple to operate and convenient to use.

[0033] In this embodiment, the guide post 21 is fixedly connected to the fixed sleeve 31 at the bottom of the workbench 3, that is, the guide post 21 can drive the workbench 3 to move up and down together, thereby driving the entire iron core 100 to move up and down. Its structure is simple and easy to disassemble and assemble.

[0034] In this embodiment, the rotating mechanism 4 includes: a receiving seat 41 disposed on the upper surface of the workbench 3 and a plurality of rolling elements 42 disposed on the receiving seat 41. The iron core 100 is placed between two of the rolling elements 42 and does not interfere with the upper surface of the receiving seat 41, so that the iron core 100 can be stably installed on the receiving seat 41 without easily shaking or shifting, thus improving its stability.

[0035] In this embodiment, the height of the base 1 is adapted to the height of the guide post 21. Preferably, the height of the base 1 is greater than the height of the guide post 21, which can avoid problems such as contact wear between the guide post 21 and the ground due to excessive length, and ensure its service life.

[0036] Of course, the length of the rolling element 42 is adapted to the thickness of the iron core 100, preferably the length of the rolling element 42 is greater than or equal to the thickness of the iron core 100. This ensures that the iron core 100 is subjected to uniform force, so that the position of the iron core 100 will not shift during lifting and rotation, resulting in strong stability.

[0037] In addition, the length of the lead screw 222 is adapted to the length of the guide post 21, preferably the length of the lead screw 222 is less than the length of the guide post 21, which can effectively avoid problems such as the guide post 21 detaching from the base 1.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
