Description

Technical Field

[0001] This utility model relates to the industrial and mining fields, specifically a hoisting tool for large motor parts. Background Technology

[0002] The current stator core hoisting jigs used for motor assembly generally have the following defects: their high specialization leads to low utilization rate; fixed-size jigs are only suitable for a single model of stator; multi-specification production lines need to repeatedly purchase special tooling, resulting in a surge in equipment costs and a high idle rate; the hoisting tooling is prone to swaying and displacement when under load, causing the stator to shake or even fall off, which seriously restricts the safety of the operation. Utility Model Content

[0003] To solve the above problems, this utility model discloses an adjustable stator core hoisting jig.

[0004] The specific technical solution is as follows:

[0005] An adjustable stator core hoisting fixture includes: a screw, a handle, a cover, a connecting rod, a movable frame, a support plate, a rubber plate, a support spring, a connecting plate, a lifting ring, and a positioning pin; the screw is provided with a stop and a locking plate, and two connecting plates are sleeved on the screw and confined between the stop and the locking plate; the inner wall of the cover is provided with a thread that mates with the external thread of the screw, and the outer wall of the cover is provided with an inclined surface with a threaded hole; the handle is obliquely installed in the threaded hole through the thread at its lower end; the movable frame consists of two upper and lower connecting plates and three vertically evenly distributed circumferentially arranged... The plates are welded together as one piece. The movable frame is sleeved on the screw and located between the two connecting plates. The support spring is located in the spring positioning groove of the connecting plate and supports the movable frame. Three sets of support units are evenly distributed around the screw. Each set includes: a support plate with two connecting blocks on one side and a positioning groove on the other side, with a rubber plate embedded in the positioning groove; two connecting rods with grooves with pin holes at both ends. One end of the connecting rod is connected to the connecting claw of the connecting plate through a positioning pin, and the other end is connected to the connecting block of the support plate through a positioning pin.

[0006] The top of the screw is provided with a lifting thread, and the lifting ring is screwed onto the lifting thread.

[0007] In the three sets of support units, the two connecting rods in the same set and the upper and lower connecting plates form a triangular structure.

[0008] The lower end of the cover is set in a plane that abuts against the upper plane of the connecting plate at the top.

[0009] A lateral semi-circular groove is provided on the support plate at the position corresponding to the connecting block.

[0010] The angle between the inclined plane and the horizontal plane is 120°-150°.

[0011] The rubber sheet and the positioning groove are fixed by interference fit or adhesive bonding.

[0012] The thickness of the connecting block is less than the width of the groove.

[0013] The advantages of this utility model are: through the coordinated design of the screw-baffle adjustment mechanism and the triangular linkage stabilization structure, stepless adjustment of the support size is achieved, adapting to stator cores with different inner diameters, and significantly reducing the purchase cost of special jigs for multi-specification production lines; the interference fit design of the modular rubber plate and the positioning groove ensures that it fits tightly against the inner wall of the core during hoisting, preventing scratches, while supporting the individual replacement of worn parts, improving economy and maintenance efficiency; the three sets of triangular linkage mechanisms evenly distributed in the circumference ensure stability and safety under heavy load conditions.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] An adjustable stator core hoisting jig, comprising:

[0023] 1. Screw; 2. Handle; 3. Cover; 4. Connecting rod; 5. Moving frame; 6. Support plate; 7. Rubber plate; 8. Support spring; 9. Connecting plate; 10. Lifting ring; and 11. Positioning pin.

[0024] The screw 1 is provided with a stop 16 and a locking platform 17, and two connecting plates 9 are sleeved on the screw 1 and limited between the stop 16 and the locking platform 17;

[0025] The inner wall of the cover 3 is provided with a thread 31 that mates with the external thread 15 of the screw 1, and the outer wall of the cover 3 is provided with an inclined surface 32 with a threaded hole 33. The handle 2 is obliquely installed in the threaded hole 33 through the thread at the lower end; the movable frame 5 is welded together by two upper and lower connecting plates 9 and three vertical plates 51 evenly distributed around the circumference. The movable frame 5 is sleeved on the screw 1 and located between the two connecting plates 9. The support spring 8 is located in the spring positioning groove 94 of the connecting plate 9 and supports the movable frame 5.

[0026] Three sets of support units are evenly distributed around the screw 1 in the circumference, each set including:

[0027] Support plate 6, with two connecting blocks 61 on one side and a positioning groove 64 on the other side, and rubber plate 7 embedded in the positioning groove 64;

[0028] Two connecting rods 4 are provided. Both ends of the connecting rods 4 are provided with grooves 42 with pin holes 41. One end of the connecting rod 4 is connected to the connecting claw 92 of the connecting plate 9 through the positioning pin 11, and the other end is connected to the connecting block 61 of the support plate 6 through the positioning pin 11.

[0029] The top end of the screw 1 is provided with a lifting thread 19, and the lifting ring 10 is screwed onto the lifting thread 19.

[0030] In the three sets of support units, the two connecting rods 4 in the same set and the upper and lower connecting plates 9 form a triangular structure.

[0031] The lower end plane of the cover 3 is set and abuts against the upper plane of the connecting plate 9 at the top.

[0032] A lateral semi-circular groove 62 is provided on the support plate 6 at the position corresponding to the connecting block 61.

[0033] The angle between the inclined plane 32 and the horizontal plane is 120°-150°.

[0034] The rubber plate 7 and the positioning groove 64 are fixed by interference fit or adhesive bonding.

[0035] The thickness of the connecting block 61 is less than the width of the groove 42.

[0036] The working principle of this utility model is as follows:

[0037] During hoisting, by turning handle 2, the internal thread 31 of cover 3 and the external thread 15 of screw rod 1 are engaged, causing cover 3 to move up and down on screw rod 1. When cover 3 is turned downwards, it pushes the moving frame 5 downwards. The moving frame 5 is an integral structure consisting of upper and lower connecting plates 9 and welded vertical plates 51. The downward movement of the moving frame compresses the support spring 8. At this time, the two ends of connecting rod 4 are connected to the connecting block 61 of support plate 6 and the connecting claw 92 of connecting plate 9 through positioning pins 11. The downward movement of moving frame 5 causes connecting rod 4 to extend outwards, causing the three support plates 6 to rotate outwards around the positioning pins 11. The rubber plate 7 on the outer side of support plate 6 fits against the inner diameter of stator core. The elastic material of rubber plate 7 deforms under force, increasing the fit with the inner diameter of stator and ensuring stable hoisting.

[0038] The stop 16 and clamp 17 on the screw 1 restrict the downward movement of the connecting plate 9, while the support spring 8 provides upward support force to maintain the stability of the moving frame 5. When the support size needs to be adjusted, the stop cover 3 is turned upward, the support spring 8 returns to its original position, causing the moving frame 5 to move upward, the connecting rod 4 to retract, and the support plate 6 to rotate inward, reducing the support size. The lifting thread 19 at the upper end of the screw 1 is used to install the lifting ring 10, enabling overall lifting operations. With the above structure, the jig can adjust the support size according to the inner diameter of the stator core, adapting to different models, and the rubber plate 7 can be replaced individually after wear, improving practicality and economy.
