Description

Technical Field

[0001] The utility model relates to the technical field of coil winding tooling, in particular to a structure of a coil winding tooling for a non-skeleton coil. Background Technique

[0002] When winding an electromagnetic coil, first, the winding shaft is connected to the chuck of the winding machine, and a lead wire is added to the end of the enameled wire. This lead wire will be wrapped inside the coil. Then, the winding machine is started to drive the winding shaft to rotate, thereby completing the winding work of the electromagnetic coil. However, if the enameled wire with the added lead wire is directly wound onto the electromagnetic coil, the initial section of the enameled wire is likely to become loose on the electromagnetic coil, which will cause a change in the tension of the initial section of the enameled wire, and then result in the problem of scattered arrangement of the enameled wire during the entire winding process. In order to improve the winding efficiency of the electromagnetic coil, a coil winding tooling is needed. However, the existing coil winding tooling still has the following deficiencies:

[0003] For example, the utility model with the application number 201720872202.4 discloses a coil winding tooling and a winding machine. The coil winding tooling and the winding machine provided by this utility model can wind transformers and reactor coils with different shapes and sizes by changing the shape and size of the baffle and adjusting the distance between the two sliders, realizing the multi-purpose function of one tooling, effectively improving the wire-changing production efficiency, reducing the tooling manufacturing cost, and improving the space utilization rate. However, for comparative documents similar to the above application, when the existing coil winding tooling is in use, since the general tooling is prone to deformation of the winding skeleton due to excessive tension during winding and is not easy to disassemble, and at the same time, because the force is inconvenient to control, the winding may be uneven and not tight, and it may also be scrapped if the force is too large.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a structure of a coil winding tooling for a non-skeleton coil is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a structure of a coil winding tooling for a non-skeleton coil to solve the problems raised in the above background technique.

[0006] To achieve the above object, the present utility model provides the following technical solutions: A structure for realizing a non-skeleton coil winding tooling, including a guiding block and a return spring. An installation groove is provided inside the guiding block, and a guiding column is provided at the lower end of the outer part of the guiding block. A positioning block is additionally provided at the lower end of the guiding block. An upper limiting groove is provided inside the guiding column. A skeleton is provided below the positioning block. A winding groove is provided on the outer part of the skeleton. An active slider is additionally provided at the lower end of the skeleton. An installation through hole is provided inside the skeleton. A guiding seat is provided below the skeleton. A limiting cavity is provided inside the upper end of the guiding seat. A return spring is installed inside the limiting cavity. A lower limiting groove is provided inside the guiding seat.

[0007] Further, the guiding block and the guiding column are in an embedded connection, and the guiding block and the guiding column are in a threaded connection.

[0008] Further, the external dimension of the positioning block matches the internal dimension of the skeleton, and the positioning block and the skeleton are in an embedded connection.

[0009] Further, the skeleton is equally cut into four parts, and the skeleton and the guiding seat are in a threaded connection.

[0010] Further, the winding groove is in a hollow cylindrical shape, and the winding grooves are equally distributed on the outer part of the skeleton.

[0011] Further, the active slider and the skeleton are vertically distributed, and the active slider and the skeleton are in a threaded connection.

[0012] Further, the active slider and the limiting cavity are in an embedded connection, and the active slider is elastically connected to the limiting cavity through the return spring.

[0013] Further, the outer side of the skeleton and the outer side of the guiding seat are closely attached, and the skeleton is slidably connected to the guiding seat through the return spring.

[0014] The present utility model provides a structure for realizing a non-skeleton coil winding tooling, having the following beneficial effects:

[0015] 1. Through the setting of the positioning block in the present utility model, when the structure of the non-skeleton coil winding tooling is used, it can avoid the problem that the stability of most winding toolings is poor during the winding operation, resulting in the tension of the electromagnetic coil being easily affected and the use efficiency of the winding tooling being reduced. The positioning block is fixedly installed at the lower end of the guiding block through a fastener, and the guiding block is installed inside the guiding column and bolt-fixed, so that the positioning block protrudes from the middle of the bottom of the guiding column. The guiding column, the skeleton, and the guiding seat are placed in sequence, and the guiding column, the skeleton, and the guiding seat are bolt-fixed by using the upper limiting groove to cooperate with the installation through hole and the lower limiting groove, so that the positioning block is embedded into the upper end of the inside of the skeleton, thereby limiting and fixing the skeleton and avoiding the position deviation of the skeleton during the winding process, and improving the overall winding efficiency.

[0016] 2. By setting the return spring, when the structure of the frameless coil winding tooling is used, it can avoid the problem that most toolings are prone to deformation of the winding frame due to excessive tension during winding, which is not easy to disassemble. At the same time, because the force is inconvenient to control, the winding may be uneven and not tight, and if the force is too large, it may even cause scrapping. The movable slider is fixedly installed in the middle of the lower end of the frame through the fastener. At the same time, the internal size of the limiting cavity opened inside the guide seat matches the external size of the movable slider. The return spring is installed inside the limiting cavity through the fastener, and the movable slider is fixedly installed at the front end of the return spring in cooperation with the fastener, so that the movable slider is elastically connected to the limiting cavity through the return spring, so that the frame slides on the upper end of the guide seat through the return spring. The cylinder is installed inside the guide block through the installation groove. The part of the cylinder extends out of its front end through the through groove opened in the middle of the positioning block. At the same time, the front part of the cylinder is closely attached to the middle part inside the frame. When the cylinder operates, the frame cut into four parts will disperse accordingly. The cable coil is wound around the outside of the frame at equal intervals through the winding groove to prevent the enameled wire from loosening and being scattered during winding. After winding, the cylinder contracts and the frame rebounds with the return spring, so that it is convenient to remove the electromagnetic coil. During the winding process, the whole tooling rotates. The structure is simple, the process is reduced, the control operation is convenient, and the assembly efficiency can be effectively improved and the coil deformation problem can be reduced.
