Description

Technical Field

[0001] This utility model relates to the field of transformer technology, specifically a transformer core stacking and flipping tool. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. Its main components include a primary coil, a secondary coil, and an iron core. The main functions of a transformer include voltage transformation, current transformation, impedance transformation, isolation, and voltage stabilization.

[0003] A search revealed a Chinese patent with publication number CN220106255U, which discloses a transformer core stacking and flipping platform. The platform includes a base with an mounting groove on its upper surface. A rotating sleeve is welded to one side of the mounting groove, and a rotating shaft is mounted on the other side of the rotating sleeve. This invention utilizes a threaded rod, with its sliding plate and placement plate shaped like the number "7". During flipping, a control motor adjusts the moving block to move horizontally, pulling the sliding plate through a support rod to rotate it, thus completing the flipping process. Conversely, adjusting the moving block uses the support rod to push the sliding plate, allowing the placement plate to lie flat.

[0004] While the above solutions can ensure worker safety during production, the flipping table in the aforementioned patent cannot guarantee the stability of the stacked iron cores during movement. When the stacked iron cores are flipped, the outermost iron core is prone to falling off. Therefore, we provide a transformer iron core stacking and flipping fixture to solve the above problems.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] Example: Figures 1-6As shown, this utility model provides a technical solution for a transformer core stacking and flipping fixture, including a stacking workbench 1 and a mounting base plate 10. A buffer shell 19 is fixedly connected to the upper surface of the mounting base plate 10, and a force-bearing slide plate 20 is slidably connected to the inner wall of the buffer shell 19. The buffer shell 19 can effectively control the position of the force-bearing slide plate 20, thereby ensuring that the force-bearing slide plate 20 can only perform vertical lifting and lowering movements.

[0026] A buffer 21 is fixedly connected to the bottom of the force-bearing slide plate 20. The bottom of the buffer 21 is fixedly connected to the inner wall of the buffer housing 19. The buffer 21 is existing technology. The buffer 21 can buffer the impact force brought by the force-bearing slide plate 20 to the greatest extent. A second tough spring 22 is sleeved on the outer circumference of the buffer 21. The force-bearing slide plate 20 contacts the lower surface of the stacking worktable 1. The purpose of setting the second tough spring 22 is to use the elasticity of the second tough spring 22 itself to further enhance the relief of the pressure brought by the force-bearing slide plate 20.

[0027] A mounting base 11 is fixedly connected to the upper surface of the mounting base plate 10. The mounting base 11 can effectively ensure that the electric push rod 12 can move stably. The electric push rod 12 is fixedly connected to the top of the mounting base 11. A U-shaped linkage frame 13 is fixedly connected to one end of the electric push rod 12. The electric push rod 12 is existing technology. The electric push rod 12 can effectively provide sufficient power support for the movement of subsequent components.

[0028] The U-shaped linkage frame 13 is slidably connected in the groove of the U-shaped support frame 14. The U-shaped support frame 14 applies a limiting effect to the U-shaped linkage frame 13, ensuring that the U-shaped linkage frame 13 can move more smoothly. The inner wall of the U-shaped support frame 14 is rotatably connected to the positioning roller 17. The U-shaped support frame 14 can effectively support the positioning roller 17, thereby ensuring that the positioning roller 17 can rotate in place.

[0029] A linkage rod 18 is fixedly connected to the outer circumference of the positioning roller 17. The positioning roller 17 and the linkage rod 18 maintain a linkage effect. One end of the linkage rod 18 is fixedly connected to the lower surface of the stacking worktable 1. When the linkage rod 18 moves, the stacking worktable 1 gradually tilts.

[0030] A force-bearing block 16 is fixedly connected to the outer circumference of the positioning roller 17. The positioning roller 17 and the force-bearing block 16 maintain a linkage effect. A drive rod 15 is slidably connected in the groove of the force-bearing block 16. The force-bearing block 16 applies a limiting effect to the drive rod 15 to ensure that the drive rod 15 moves in a designated position, thereby causing the positioning roller 17 to rotate.

[0031] Both ends of the drive rod 15 are rotatably connected to the U-shaped linkage frame 13, and the bottom of the U-shaped support frame 14 is fixedly connected to the upper surface of the mounting base plate 10. The drive rod 15 and the U-shaped support frame 14 are linked together, and the U-shaped support frame 14 drives the drive rod 15 to move horizontally.

[0032] A U-shaped limiting rod 2 is slidably connected to the inner wall of the stacking worktable 1. The stacking worktable 1 applies a limiting effect to the U-shaped limiting rod 2 to ensure that the U-shaped limiting rod 2 will not tilt or jam during movement. A control guide rod 3 is fixedly connected to one side of the U-shaped limiting rod 2. The outer circumferential surface of the control guide rod 3 is slidably connected to the inner wall of the stacking worktable 1. The control guide rod 3 and the U-shaped limiting rod 2 maintain a linkage effect. The control guide rod 3 is also controlled by the stacking worktable 1.

[0033] A component protective shell 4 is fixedly connected to one side of the stacking workbench 1. The component protective shell 4 can effectively control the position of the control guide rod 3 and enhance the stability of the control guide rod 3. A control sleeve 5 is fixedly connected to the top of the component protective shell 4. An external push rod 6 is slidably connected to the inner wall of the control sleeve 5. The external push rod 6 is convenient for the staff to operate at any time.

[0034] One end of the external push rod 6 is fixedly connected to a force-bearing disc 7. The outer circumferential surface of the force-bearing disc 7 is slidably connected to the inner wall of the control sleeve 5. The force-bearing disc 7 moves up and down inside the control sleeve 5. The bottom of the force-bearing disc 7 is fixedly connected to a friction limiting rod 8. The friction limiting rod 8 contacts the control guide rod 3. The friction limit rod 8 ensures that the control guide rod 3 will not slide arbitrarily through the friction generated by its contact with the control guide rod 3.

[0035] A resilient spring 9 is fixedly connected to the top of the force-bearing disc 7. The resilient spring 9 is designed to effectively enhance the friction between the friction limiting rod 8 and the control guide rod 3 by utilizing its own elasticity. At the same time, it allows the friction limiting rod 8 to be inserted into the groove opened in the control guide rod 3, thereby limiting the control guide rod 3 and ensuring its stability. One end of the resilient spring 9 is fixedly connected to the inner wall of the control sleeve 5.

[0036] Working principle: When using this fixture, the iron cores are stacked on the stacking worktable 1. An external force pushes the control guide rod 3 to move, causing the U-shaped limiting rod 2 to gradually exit the stacking worktable 1, thus restricting the iron cores. When the groove on the control guide rod 3 moves to the designated position, under the elasticity of the spring-9, the force-bearing disc 7 drives the friction limiting rod 8 downwards, causing it to insert into the groove on the control guide rod 3. This restricts the control guide rod 3 and strengthens the stability of the U-shaped limiting rod 2 connected to the control guide rod 3. The electric push rod 12 is activated, which pulls the force block 16 to slide within the U-shaped support frame 14 via the U-shaped linkage frame 13. This causes the force block 16 to drive the positioning roller 17 to rotate in place within the U-shaped support frame 14. At this time, the drive rod 15 slides within the groove of the force block 16, and the positioning roller 17 drives the stacking worktable 1 to move via the linkage rod 18, gradually changing the stacking worktable 1 from a horizontal position to a vertical position. During the movement of the stacking worktable 1, the U-shaped limit rod 2 continuously controls the position of the stacked iron cores, ensuring that the outermost iron core does not fall off.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
