Description

Technical Field

[0001] The utility model relates to the technical field of motor manufacturing, in particular to a stator lifting and turning tool. Background Art

[0002] The motor stator is typically placed horizontally for wire embedding, then flipped upright for wiring, wire binding, varnishing, and casing insertion. Due to its heavy weight, manual flipping by a single person is difficult, and manual flipping can easily lead to accidents, damaging the stator or even injuring the operator. It also makes the motor difficult to transport.

[0003] Although the patent application with publication number CN220915115U discloses a structure that facilitates flipping of the stator, the structure has the following shortcomings: 1. The flip frame is a closed circular ring structure. For a stator placed horizontally on a table, part of the outer wall of the stator is pressed on the table surface, and the flip frame cannot be directly put on the stator. For a stator with a heavier weight, the staff cannot lift the stator to allow the flip frame to be inserted; 2. There are screw heads in the flip frame, and the flip frame cannot fit the outer circle of the stator with the maximum area, thereby affecting the locking force between the flip frame and the stator, and then affecting the safety of lifting.

[0004] It can be seen that the existing technology still needs to be improved and enhanced. Utility Model Content

[0005] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a stator lifting and turning tool that is easy to install with the stator and has high lifting safety performance.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A stator lifting and turning tool comprises a door-shaped frame, a lifting ring arranged on a horizontal bar of the door-shaped frame, and at least one set of clamping ring assemblies arranged between two vertical bars of the door-shaped frame; the clamping ring assembly comprises a clamping ring with a superior arc structure and a handle arranged on the outer wall of the clamping ring; the clamping ring is provided with a threaded hole connecting its inner and outer walls, and each threaded hole is installed with a clamping screw screwed into the center of the clamping ring.

[0008] As a further improvement of the above technical solution, the clamping ring is rotatably connected to the two vertical rods of the door-shaped frame through a pivot, and the two vertical rods of the door-shaped frame are provided with locking screws for limiting the relative rotation of the vertical rods and the pivot.

[0009] As a further improvement of the above technical solution, the handle is arranged at the symmetrical center of the outer arc surface of the clamping ring, and two clamping screws are provided on the clamping ring and are respectively arranged close to the two ends of the clamping ring.

[0010] As a further improvement of the above technical solution, the clamping ring assembly is provided with two groups and arranged in a front-to-back manner, a spacer is sandwiched between the clamping rings of the two groups of clamping ring assemblies, and the clamping rings are fixed to the spacer by connecting screws.

[0011] As a further improvement of the above technical solution, the spacer is rotatably connected to the two vertical rods of the door-shaped frame via a pivot, and the two vertical rods of the door-shaped frame are provided with locking screws for limiting the relative rotation of the vertical rods and the pivot.

[0012] As a further improvement of the above technical solution, the handle is arranged at the symmetrical center of the outer arc surface of the clamping ring, and there are four clamping screws on the clamping ring, two of which are arranged close to the two ends of the clamping ring, and the remaining two clamping screws are arranged on both sides of the handle.

[0013] As a further improvement of the above technical solution, a triangular reinforcement block is provided at the connection between the horizontal rod and the vertical rod of the door-shaped frame.

[0017] 3. The clamping ring of the present invention does not have protrusions such as screw heads, and can fit the outer circle of the stator with the maximum area, so that the inner wall of the clamping ring and the outer wall of the stator are fully and tightly contacted to form an embracing connection, thereby enhancing the matching locking force and improving the safety during the lifting process.

DETAILED DESCRIPTION

[0023] The present invention provides a stator lifting and turning tool. To make the purpose, technical solution, and effects of the present invention more clear and explicit, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific examples described herein are only intended to illustrate the present invention and are not intended to limit the scope of protection of the present invention.

[0024] See also Figure 1 The utility model provides a stator lifting and flipping tool, including a door-shaped frame 1, a lifting ring 2 arranged on the horizontal rod 11 of the door-shaped frame 1, and at least one set of clamping ring assemblies 3 arranged between two vertical rods 12 of the door-shaped frame 1; the clamping ring assembly 3 includes a clamping ring 31 with a superior arc structure, and a handle 32 arranged on the outer wall of the clamping ring 31. The clamping ring 31 is provided with a threaded hole 311 connecting the inner and outer walls thereof, and each threaded hole 311 is installed with a clamping screw 33 screwed into the center of the clamping ring 31.

[0025] The working principle is briefly described below: After the embedding is completed on the horizontal table, the clamping ring 31 is first put on the stator 6. Since the clamping ring 31 is a superior arc structure, the clamping ring 31 will not interfere with the table. After the clamping ring 31 is put on the stator 6, it will form a clearance fit with the stator 6. Then tighten the clamping screw 33 so that the inner wall of the clamping ring 31 and the outer wall of the stator 6 are fully and firmly in contact to form an embracing connection. Then the hook of the crane hooks the lifting ring 2, lifts the tooling and stator 6 and lifts them to a suitable position for subsequent operation. In the process of lowering the stator 6, the staff can easily drive the stator 6 to flip to an upright position by pulling the handle 32. Finally, after the stator 6 is lowered, the stator 6 is placed in an upright manner, the clamping screw 33 is loosened, and the tooling is removed.

[0026] Compared with the prior art, the stator lifting and flipping tooling provided by the present invention has the following advantages: 1. The clamping ring 31 of the present invention adopts a superior arc structure. After the horizontally placed stator 6 is completed with wire embedding, it can be easily put on the stator 6 without interfering with the desktop. This solves the problem in the prior art that the closed circular ring structure flip frame cannot be directly put on the stator 6 and it is difficult for the staff to lift the stator 6 for the flip frame to be inserted, greatly improving the convenience of operation.

[0027] 2. In the process of lowering the stator 6, the staff can easily drive the stator 6 to flip to stand upright by pulling the handle 32, without consuming too much physical strength, and the operation is simple and efficient.

[0028] 3. The retaining ring 31 of the present invention does not have any protrusions such as screw heads, and can fit the outer circle of the stator 6 with the maximum area, so that the inner wall of the retaining ring 31 and the outer wall of the stator 6 are fully and firmly in contact to form an embracing connection, thereby enhancing the matching locking force and improving the safety during the lifting process.

[0029] Furthermore, the snap ring 31 is rotatably connected to the two vertical rods 12 of the portal frame 1 via a pivot 41. Locking screws 5242 are provided on the two vertical rods 12 of the portal frame 1 to limit relative rotation between the vertical rods 12 and the pivot 41. This arrangement allows for an adjustable angle between the snap ring 31 and the portal frame 1. The portal frame 1 can adjust its angle as needed, better adapting to different operating scenarios and space constraints, and improving the flexibility and adaptability of lifting operations.

[0030] Furthermore, the handle 32 is positioned at the symmetrical center of the outer arc surface of the clasp 31. This allows the operator to apply force more evenly and smoothly when pulling the handle 32 to flip the stator 6. This allows the operator to easily adjust the center of gravity of the stator 6 to an upright position, reducing operational difficulty. The clasp 31 is provided with two clamping screws 33, one located near each end of the clasp 31. When the clamping screws 33 are tightened to secure the clasp 31 to the stator 6, even force is applied from both ends, ensuring a tighter and more reliable connection between the clasp 31 and the stator 6 and improving the stability of the clasp connection.

[0031] See Figure 2-Figure 4 As shown, in order to be suitable for the lifting and flipping of large stators 6, this embodiment further improves the stator lifting and flipping tooling. The clamping ring assembly 3 is provided with two groups and arranged in a front-to-back manner. A spacer 51 is sandwiched between the clamping rings 31 of the two groups of clamping ring assemblies 3, and the clamping ring 31 is fixed to the spacer 51 by connecting screws. For large stators 6, which are heavy and large in size, a single group of clamping ring assemblies 3 may not provide sufficient stability and support. The two groups of clamping ring assemblies 3 work together to share the weight of the large stator 6, reduce the force on a single clamping ring assembly 3, and reduce the risk of deformation or damage to the clamping ring 31. This can better meet the lifting and flipping requirements of large stators 6 and ensure the stability and safety of the large stator 6 during the lifting and flipping process.

[0032] Furthermore, the spacer 51 is rotatably connected to the two vertical rods 12 of the portal frame 1 via the pivot 41. Locking screws 5242 are provided on the two vertical rods 12 of the portal frame 1 to limit the relative rotation of the vertical rods 12 and the pivot 41. This arrangement allows the angle between the retaining ring 31 and the portal frame 1 to be adjustable. The portal frame 1 can adjust its angle according to actual needs, better adapting to different operating scenarios and space constraints, and improving the flexibility and adaptability of lifting operations.

[0033] Furthermore, the handle 32 is positioned at the symmetrical center of the outer arc surface of the clasp 31, so that when the operator pulls the handle 32 to drive the stator 6 to flip, the force applied is more balanced and stable, and the flipping operation of the stator 6 can be completed more easily, greatly improving the convenience of operation. In this embodiment, there are four clamping screws 33 on the clasp 31, two of which are positioned near the two ends of the clasp 31, and the remaining two clamping screws 33 are positioned on both sides of the handle 32. The reasonable distribution further enhances the clamping effect between the clasp 31 and the stator 6, making the stator 6 more stable and reliable during the lifting process. The provision of four clamping screws 33 increases the contact points and tightening force between the clasp 31 and the stator 6, effectively preventing the stator 6 from loosening or slipping during lifting and flipping, and greatly improving the safety of operation.

[0034] Furthermore, triangular reinforcement blocks 13 are installed at the junctions between the horizontal bars 11 and vertical bars 12 of the portal frame 1. These blocks significantly enhance the structural strength of the portal frame 1. During the lifting and turning of the stator 6, the portal frame 1 is subjected to significant forces, which can lead to stress concentrations at the junctions between the horizontal bars 11 and vertical bars 12. The provision of triangular reinforcement blocks 13 effectively disperses these stresses, preventing breakage or deformation at the junctions and ensuring the overall stability and reliability of the tooling.
