Description

Technical Field

[0001] This utility model belongs to the field of equipment for transformer production, and in particular relates to a partial mechanism for an automatic wire laying device for transformer production. Background Technology

[0002] A transformer mainly consists of an iron core, windings, insulation, and accessories. The windings, also known as coils, are the part of the transformer that conducts current. The main task of transformer winding operations is to wind the transformer coils. Traditionally, this was done manually, but now workshops use automated winding machines, effectively improving production efficiency.

[0003] Most existing transformer winding frames generally include components such as the frame, main shaft mechanism, tailstock, and center. Since the center can cooperate with the main shaft to improve the rotational center accuracy of the coil, the main shaft mechanism used for coil winding is equipped with a support rod that cooperates with the coil. The end of the support rod has a tapered groove that cooperates with the center. However, the axial movement of the coil is difficult to control. Chinese utility model patent CN215118629U discloses a transformer winding frame with adjustable width. Although this device can limit the axial position of the coil, it lacks the centering function of the center, thus directly affecting the quality of coil winding. Utility Model Content

[0004] This utility model addresses the technical problems existing in the aforementioned automatic transformer winding equipment by proposing a locally designed automatic winding device for transformer production that can reduce the axial movement of the coil and help ensure winding efficiency.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: The partial mechanism of the automatic wire laying device for transformer production provided by this utility model includes a support rod, the end of which is provided with a tapered blind hole. The support rod includes a square tube, and a baffle is provided on the square tube near the main shaft mechanism. Multiple pairs of positioning holes are provided on the square tube away from the main shaft mechanism. A limiting mechanism is provided on the support rod. The limiting mechanism includes a grid-shaped frame. A rod assembly penetrating the grid-shaped frame and the positioning holes is provided on one pair of sides of the grid-shaped frame. The rod assembly includes a hollow outer rod, one end of which is provided with a handle. An inner rod is provided inside the outer rod. Two spaced automatic springs are provided on the inner rod. One end of each automatic spring is provided with a spring pin, which is used to cooperate with a pin hole and a radial hole provided on the outer rod.

[0006] Preferably, the grid-shaped frame has two through tubes on its inner sides, and the through tubes have pin holes on their sides, which cooperate with the insertion rod assembly.

[0007] Preferably, the inner rod is provided with a mounting groove for installing an automatic spring.

[0008] Preferably, the spring pin is hollow inside, with one end being a spherical surface and the other end being open.

[0009] Compared with the prior art, the advantages and positive effects of this utility model are as follows: The partial mechanism of the automatic wire laying device for transformer production provided by this utility model can be quickly installed on the support rod by adopting a grid-shaped frame limiting mechanism. Together with the baffle, it forms a clamping mechanism for the coil, effectively limiting the axial movement of the coil. The design is reasonable and retains the centering function of the top, which helps to ensure the quality of automatic wire laying and is suitable for large-scale promotion.

[0012] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0013] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0014] Examples, such as Figures 1-4 As shown, the partial mechanism of the automatic wire-laying device for transformer production provided by this utility model includes a support rod 1. The end of the support rod 1 is provided with a tapered blind hole 11, which is used to mate with the center of the wire-laying machine. The support rod 1 includes a square tube 12. A baffle 13 is provided on the square tube 12 near the main shaft mechanism. Multiple pairs of positioning holes 14 are provided on the square tube 12 away from the main shaft mechanism. A limiting mechanism is provided on the support rod 1. The limiting mechanism includes a grid-shaped frame 21. A pair of sides of the 21 are provided with a rod assembly 22 that passes through the grid-shaped frame 21 and the positioning hole 14. The rod assembly 22 includes a hollow outer rod 221. One end of the outer rod 221 is provided with a handle 222. An inner rod 223 is provided inside the outer rod 221. Two spaced automatic springs 224 are provided on the inner rod 223. One end of the automatic spring 224 is provided with a spring pin 225. The spring pin 225 is used to cooperate with the pin hole 24 and the radial hole 226 provided on the outer rod 221.

[0015] Specifically, during the production of transformer coils, end flanges or other tooling structures are generally provided at the center and both ends. These are not removed before the transformer is assembled, so they can be inserted into the support rod 1 to complete the wiring operation. The support rod 1 adopts a square tube 12 structure to cooperate with the coil support. The grid frame 21 can be quickly installed on the support rod 1. The insertion rod assembly 22 is inserted into the corresponding positioning hole 14 to maintain the predetermined position, thereby forming a clamping of the coil with the baffle 13, thus effectively limiting the axial movement of the coil. Regarding the insertion rod assembly 22, one end of the inner rod 223 is provided with a tip and its diameter is smaller than that of the through tube 23, which can be held by hand to facilitate the insertion of the inner rod 223 into the interior of the outer rod 221; the inner rod 223, together with the automatic spring 224 and the spring pin 225, is inserted into the outer rod 221. The pressure of the automatic spring 224 can cause the spring pin 225 to pop out when it is close to the radial hole 226. By holding the handle 222 and inserting the insertion rod assembly 22 into the grid frame 21 until the spring pin 225 pops out from the pin hole 24, the limiting mechanism can be fixed; by manually pressing the spring pin 225 to compress it a certain distance towards the inner rod 223, the insertion rod assembly 22 can be held away from the grid frame 21, thereby completing the quick removal of the grid frame 21.

[0016] Furthermore, the grid-shaped frame 21 provided by this utility model has two through tubes 23 on a pair of inner sides, and the sides of the through tubes 23 are provided with pin holes 24, which cooperate with the insertion rod assembly 22. The grid-shaped frame 21 not only provides an effective cross support span for the end of the coil, especially suitable for non-circular coils, but also provides through tubes 23 to limit left and right swaying, and can be quickly engaged with the insertion rod assembly 22 through the pin holes 24.

[0017] To ensure the retraction and extension performance of the spring pin 225, the inner rod 223 provided by this utility model is provided with a mounting groove for installing the automatic spring 224. The mounting groove allows for radial compression space for the automatic spring 224 and the spring pin 225, enabling them to effectively retract into the inner rod 223, facilitating the assembly of the outer rod 221 and the inner rod 223 by a pull-in method.

[0018] Furthermore, the spring pin 225 provided by this utility model is hollow inside, with one end of the spring pin 225 having a spherical surface and the other end being open. The two ends of the automatic spring 224 are spot-welded to the mounting groove and the inner top of the spring pin 225. The spherical surface of the spring pin 225 can provide an effective transition surface for its fit with the pin hole 24 and the radial hole 226, avoiding jamming; the hollow design of the spring pin 225 can work with the automatic spring 224 to create better internal conditions, facilitating assembly and automatic ejection.

[0019] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
