Description

Technical Field

[0001] This application relates to the technical field of stacked workbenches, and specifically to a pre-stacking workbench for transformer assembly. Background Art

[0002] The iron core is the main magnetic circuit part in a transformer, usually made of hot-rolled or cold-rolled silicon steel sheets with a relatively high silicon content and an insulating paint coated on the surface. During the production process of stacking the transformer iron core, stacking tooling is required.

[0003] The Chinese utility model patent with the authorization announcement number CN218585789U discloses a dry-type transformer iron core stacking workbench. It drives the movement by starting the motor to quickly align the iron cores on the left and right sides and the front side automatically; after the alignment is completed, the push plate is controlled to move backward and the limit frame moves downward to facilitate workers to take out the aligned iron cores. However, this workbench lacks a horizontal adjustment mechanism. In actual use of the workbench, affected by the ground, when the ground is uneven, the workbench is prone to tilt or shake. The tilted or shaken workbench is likely to cause the stacked laminations on it to become unstable and fall over.

[0004] Therefore, this application provides a pre-stacking workbench for transformer assembly to solve the above problems. Utility Model Content

[0005] This application provides a pre-stacking workbench for transformer assembly, aiming to solve the problems in the background art that the existing workbench lacks a horizontal adjustment mechanism, the workbench is prone to tilt or shake when the ground is uneven, and the tilted or shaken workbench is likely to cause the stacked transformer laminations on it to become unstable and fall over.

[0006] To achieve the above object, this application provides the following technical solution: A pre-stacking workbench for transformer assembly, including a bracket, a plurality of cross frames arranged equidistantly on the bracket, and an adjustment mechanism for horizontally adjusting the cross frames;

[0007] To facilitate the horizontal adjustment of the workbench: The adjustment mechanism includes a fixing plate fixedly arranged at one end of the bracket away from the cross frame, a threaded rod threadedly inserted into the fixing plate, a support leg fixedly arranged at the end of the threaded rod away from the bracket, and a hexagonal plate fixedly sleeved on the threaded rod near one end of the support leg for driving the threaded rod to rotate; when horizontally adjusting the workbench, by rotating the hexagonal plate to drive the threaded rod to rotate, the threaded rod drives the support leg to move closer to or away from the fixing plate to adjust the horizontal plane of the workbench. The structure is simple and the operation is convenient. The horizontal workbench can prevent the stacked transformer laminations from tilting.

[0008] For the convenience of supporting transformer laminations, a support structure is provided at one end of the cross-frame away from the bracket. The support structure includes support frames fixedly arranged on the cross-frame at equal intervals and a support plate fixedly arranged on the support frames. When assembling the transformer laminations, the cooperation of the support frames and the support plate facilitates the support and placement of the transformer laminations; at the same time, when the assembly of the transformer laminations is completed, the gap between adjacent support frames facilitates the hoisting of the assembled laminations.

[0009] Preferably, in order to ensure the stability of the connection between the threaded rod and the fixed plate, a hexagonal nut is threadedly sleeved on the threaded rod near the fixed plate and is in contact with the bottom end of the fixed plate for locking the connection between the threaded rod and the fixed plate. After the threaded rod and the fixed plate are adjusted, by rotating the hexagonal nut clockwise, the hexagonal nut moves along the threaded rod towards the fixed plate until the top end of the hexagonal nut is in close contact with the bottom end of the fixed plate and then stops. The hexagonal nut can also provide a certain support for the fixed plate.

[0010] Preferably, in order to reduce the vibration force transmitted by the ground to the support feet, a shock pad for damping the bracket is fixedly connected to one end of the support feet away from the fixed plate. The shock pad can not only reduce the vibration force transmitted by the ground to the support feet, but also increase the friction between the support feet and the ground to prevent the support feet from moving on the ground.

[0011] Preferably, in order to reduce costs, the support frame is designed to be hollow. The hollow support frame can reduce the use of materials and thus reduce costs.

[0012] Preferably, in order to improve the flatness of the plane where the support plate contacts the lamination, the surface of the support plate away from the support frame is a smooth plane. By milling the upper surface of the support plate, the smoothness of the surface of the support plate can be ensured, avoiding scratches on the lamination caused by the support plate.

[0013] Preferably, in order to facilitate fixing the transformer laminations on the support plate, positioning holes for inserting positioning pins are equally spaced on the support plate and the support frame. When fixing the laminations, it only needs to insert the positioning pins through the laminations and plug them into the corresponding positioning holes to complete the locking of the laminations.

[0014] When the present application adjusts the horizontal level of the workbench, by rotating the hexagonal plate to drive the threaded rod to rotate, the threaded rod drives the support feet to move closer to or away from the fixed plate to adjust the horizontal plane of the workbench. The structure is simple and the operation is convenient. The horizontal workbench can prevent the stacked transformer laminations from tilting.

[0015] When assembling the transformer laminations in this application, the cooperation between the support frame and the support plate facilitates the support and placement of the transformer laminations; at the same time, when the transformer laminations are assembled, the gap between adjacent support frames facilitates the hoisting of the assembled laminations.

[0022] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0023] Embodiment 1

[0024] This embodiment provides a pre-laminating workbench for transformer assembly, as Figures 1-4 shown, the workbench includes a bracket 1, a plurality of cross frames 2 arranged equidistantly on the bracket 1, and an adjusting mechanism 3 for horizontally adjusting the cross frames 2;

[0025] For the convenience of horizontal adjustment of the workbench: The adjusting mechanism 3 includes a fixing plate 31 fixedly arranged at one end of the bracket 1 far away from the cross frame 2, a threaded rod 32 threadedly inserted into the fixing plate 31, a supporting foot 33 fixedly arranged at one end of the threaded rod 32 far away from the bracket 1, and a hexagonal plate 34 fixedly sleeved on the threaded rod 32 near one end of the supporting foot 33 for driving the threaded rod 32 to rotate; when horizontally adjusting the workbench, by rotating the hexagonal plate 34 to drive the threaded rod 32 to rotate, the threaded rod 32 drives the supporting foot 33 to move closer to or away from the fixing plate 31 to adjust the horizontal plane of the workbench. The structure is simple and the operation is convenient. The horizontal workbench can prevent the stacked transformer laminations from tilting.

[0026] During use, when the hexagonal plate 34 is rotated clockwise, the hexagonal plate 34 drives the threaded rod 32 and the supporting foot 33 to move in the direction close to the fixing plate 31, and the corner of the workbench where the adjusted supporting foot 33 is located moves downward; when the hexagonal plate 34 is rotated counterclockwise, the hexagonal plate 34 drives the threaded rod 32 and the supporting foot 33 to move in the direction away from the fixing plate 31, and the corner of the workbench where the adjusted supporting foot 33 is located moves upward.

[0027] For the convenience of supporting the transformer laminations, a supporting structure 4 is arranged at one end of the cross frame 2 far away from the bracket 1. The supporting structure 4 includes a supporting frame 41 fixedly arranged on the cross frame 2 at equal intervals and a supporting plate 42 fixedly arranged on the supporting frame 41. When assembling the transformer laminations, the cooperation of the supporting frame 41 and the supporting plate 42 facilitates the supporting and placing of the transformer laminations; at the same time, when the transformer laminations are assembled, the gap between adjacent supporting frames 41 facilitates the hoisting of the assembled laminations.

[0028] Specifically, in order to ensure the stability of the connection between the threaded rod 32 and the fixing plate 31, a hexagonal nut 321 for locking the connection between the threaded rod 32 and the fixing plate 31 by contacting the bottom end of the fixing plate 31 is threadedly sleeved on the threaded rod 32 near one end of the fixing plate 31. After the threaded rod 32 and the fixing plate 31 are adjusted, by rotating the hexagonal nut 321 clockwise, the hexagonal nut 321 moves along the threaded rod 32 close to the fixing plate 31 until the top end of the hexagonal nut 321 is in close contact with the bottom end of the fixing plate 31 and then stops. The fixing plate 31 can also be supported to a certain extent by the hexagonal nut 321.

[0029] Specifically, in order to reduce the vibration force transmitted by the ground to the support leg 33, a shock pad 331 for damping the support 1 is fixedly connected to one end of the support leg 33 away from the fixed plate 31. The shock pad 331 is made of hydrogenated nitrile rubber and has excellent corrosion resistance, tear resistance and compression deformation characteristics, good ozone resistance, sunlight resistance and weather resistance, and better wear resistance than nitrile rubber, and performs stably under high temperature and harsh environments. Through the shock pad 331, not only can the vibration force transmitted by the ground to the support leg 33 be reduced, but also the friction between the support leg 33 and the ground can be increased to prevent the support leg 33 from moving on the ground.

[0030] Specifically, in order to reduce costs, the support frame 41 is designed to be hollow. By means of the hollow support frame 41, the use of materials can be reduced, thereby reducing costs.

[0031] Specifically, in order to improve the flatness of the plane where the support plate 42 contacts the laminated sheet, the surface of the support plate 42 away from the support frame 41 is a smooth plane. By milling the upper surface of the support plate 42, the smoothness of the surface of the support plate 42 can be ensured, and scratches on the laminated sheet caused by the support plate 42 can be avoided.

[0032] Embodiment 2

[0033] Different from Embodiment 1, (when the laminated sheet is impacted, there will be a problem that the laminated sheet is displaced on the support plate 42). For this reason, positioning holes 5 for inserting positioning pins are equidistantly opened on the support plate 42 and the support frame 41. When fixing the laminated sheet, it only needs to insert the positioning pin through the laminated sheet and plug it into the corresponding positioning hole 5 to complete the locking of the laminated sheet.

[0034] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application, according to the technical solution and its concept of the present application, makes equivalent replacements or changes, and should be covered by the protection scope of the present application.
