Description

Technical Field

[0001] The invention relates to the technical field of transformer winding, and in particular to a transformer winding positioning tool. Background Art

[0002] As an indispensable and important equipment in the power system, transformers are widely used in power transmission and distribution. Its main function is to convert electrical energy between different voltage levels through the principle of electromagnetic induction. The performance of the transformer directly affects the safety and stability of the power system. Therefore, in the manufacturing process of the transformer, the accuracy and stability of the winding process are particularly important.

[0003] In traditional transformer winding production, winding positioning is usually performed manually or with simple mechanical equipment. These methods have multiple shortcomings. First, manual operation is easily affected by human factors, resulting in inaccurate positioning during the winding process, which in turn affects the electrical performance and operational stability of the transformer. Secondly, the existing winding positioning tooling is not flexible enough to adapt to winding tubes of different sizes, and it is difficult to adjust quickly, resulting in low production efficiency. In addition, traditional transmission systems often lack stability, resulting in uneven rotation of the screw, which affects the overall quality of the winding.

[0004] In addition, the existing guide mechanism and tensioning mechanism are relatively simple in design and cannot effectively prevent the displacement of the nut during rotation, resulting in reduced positioning accuracy and increased workload for subsequent adjustment and correction. At the same time, many traditional tooling is not convenient enough in installation and operation, which increases the difficulty of maintenance and adjustment and reduces production efficiency.

[0005] In view of the above problems, a new type of winding positioning tool is urgently needed to improve the accuracy and stability of the transformer winding process. This new tool should have an efficient transmission system, flexible dimensional adaptability, a stable guide mechanism and a reliable tensioning mechanism, which can improve the quality and performance of the final product while ensuring production efficiency, and provide support for the technological progress and development of the transformer manufacturing industry.

[0051] Please refer to the instruction manual Figure 1-Figure 5 The present invention provides a transformer winding positioning tool:

[0052] The basic structure of tooling

[0053] The transformer winding positioning tool comprises a positioning sleeve 1 integrally provided with left and right through-holes 11. A guide through-hole 13 is provided at the top of the positioning sleeve 1, and a nut 3 is slidably connected in the guide through-hole 13, and the nut can be inserted into the interior of the positioning sleeve 1. A screw rod 2 distributed along the length direction is installed inside the positioning sleeve, and the nut 3 is threadedly sleeved on the top of the screw rod 2.

[0054] The left and right sides of the positioning sleeve 1 are provided with tensioning components 6 for tightening the positioning winding tube from the inside and preventing it from sliding. A nut slider 4 that is connected to the bottom end of the nut is slidably sleeved on the screw rod, and the slider can slide on the screw rod as the nut 3 moves.

[0055] Linked transmission of screw and tensioner assembly

[0056] The rotation of the screw 2 is controlled by a screw driving mechanism 7 at the bottom end, and the driving mechanism is installed in a fixing seat 8 of the positioning sleeve 1 to drive the screw to rotate.

[0057] When the screw rotates, the nut 3 moves along the axial direction of the screw 2, and the movement of the nut is transmitted to the tensioning assembly 6 on the same side through the tensioning transmission member 5 by the sliding nut slider 4, thereby realizing the internal tensioning and positioning operation of the winding tube.

[0058] The tensioning transmission member 5 specifically includes the following structure:

[0059] A connecting protrusion 51 installed on the inner end surface of the tensioning assembly 6;

[0060] Connect the nut slider 4 and the front movable link 52 at the top of the connecting protrusion 51 on the same side by screws;

[0061] The connecting protrusion 51 on the same side and the rear movable connecting rod 53 on the inner wall of the positioning sleeve 1 are connected by screws.

[0062] Specific structure of the tensioning assembly

[0063] The tensioning assembly 6 includes a tensioning plate 61 installed on the side of the positioning sleeve 1, and side tightening convex strips 64 are provided on the front and rear sides of the tensioning plate 61. A double-axis telescopic cylinder 62 is installed at the center of the tensioning plate, and the piston rod 63 of the cylinder is respectively connected to the front and rear side tightening convex strips 64. Under the action of the cylinder, the piston rod pushes the side tightening convex strips 64 to extend outward, thereby realizing the tensioning operation on the front and rear sides of the tensioning end surface of the tensioning plate 61 inside the winding tube, and then realizing the positioning operation on the front, rear, left and right side walls inside the winding tube.

[0064] Screw drive mechanism

[0065] The screw drive mechanism 7 uses a reduction motor 71 to provide power, and the reduction motor is installed at the bottom of the fixed seat 8. The output end of the reduction motor is connected to the driving gear 72, and the driving gear is meshed with the transmission gear 73. The transmission gear drives the driving shaft 75 to rotate through the driven gear 74, and finally drives the screw 2 to rotate. The rotation of the screw 2 realizes the movement of the nut 3 along the axial direction.

[0066] Matching of nut and guide rib

[0067] In order to ensure the stable movement of the nut 3, guide ridges 31 are provided on the front, rear, left and right side walls thereof. These guide ridges are distributed along the movement direction of the nut and cooperate with the grooves inside the guide through holes 13 at the top of the positioning sleeve, thereby ensuring that the nut 3 does not rotate with the screw 2, so that it can convert the rotation of the screw 2 into power to drive it to move axially.

[0068] The role of the mounting plate

[0069] A mounting plate 9 is installed at the bottom end of the tooling, and the mounting plate is used to fix the entire tooling to the driving end of the rotating workpiece to ensure that the tooling can operate stably during operation.

[0070] How it works

[0071] The entire tooling is positioned on the driving end of the rotating workpiece through the mounting plate 9.

[0072] Start the reduction motor 71, the output end of the reduction motor 71 drives the driving gear 72 to rotate, the driving gear 72 drives the transmission gear 73 to rotate through meshing, the transmission gear 73 then drives the driven gear 74 to rotate through meshing, the driven gear 74 drives the driving shaft 75 to rotate, and then drives the screw 2 to rotate.

[0073] When the screw rod 2 rotates, the nut 3 threadedly sleeved on the top end thereof moves along the axial direction of the screw rod 2.

[0074] When the nut 3 moves, it pushes the nut slider 4 connected to its bottom end to slide on the screw rod 2.

[0075] The nut slider 4 transmits the motion to the connecting protrusion 51 through the front movable link 52 and the rear movable link 53 , and the connecting protrusion 51 transmits the motion to the tensioning assembly 6 .

[0076] For the tensioning assembly 6, when the motion signal is received, the double-axis telescopic cylinder 62 works, and the piston rod 63 at the front and rear output ends thereof pushes the side tightening convex strip 64 to extend outward. The side tightening convex strip 64 is installed on the outside of the front and rear sides of the tensioning plate 61. As the side tightening convex strip 64 extends, the anti-slip convex strip 66 on the outer end surface of the tensioning plate 61 contacts the inner wall of the winding tube and generates pressure, thereby realizing the tensioning and positioning operation inside the winding tube.

[0077] For winding tubes of different sizes, the rotation amount of the screw 2 can be adjusted by controlling the working time and speed of the reduction motor 71, thereby controlling the moving distance of the nut 3, and finally achieving the internal tightening and positioning operation of winding tubes of different sizes. During the adjustment process, the sliding of the guide column 65 inside the tightening plate 61 can ensure that the side tightening convex strip 64 is stretched smoothly.

[0078] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
