Description

Technical Field

[0001] This utility model belongs to the technical field of generator winding equipment, specifically relating to an auxiliary winding device for generator production coils. Background Technology

[0002] A generator is a mechanical device that converts other forms of energy into electrical energy. It is driven by a water turbine, steam turbine, diesel engine or other power machinery. A generator needs to be equipped with coils, which are wire windings.

[0003] In existing coils, the conductors used before winding are generally wound uniformly on a take-up reel, and the coil is wound by a rotating device. However, when the coil stops winding, the take-up reel continues to release wire due to inertia, which reduces the tension of the conductor or even makes it loose, affecting the tightness of subsequent winding and making it easy to get tangled, thus affecting the normal production of coils.

[0004] Therefore, an auxiliary winding device for generator production is proposed. Summary of the Invention

[0005] This utility model provides an auxiliary winding device for generator production coils, the purpose of which is to solve the problems mentioned above.

[0006] This utility model provides a coil auxiliary winding device for generator production, including a base plate; a guide wheel rotatably mounted on one outer wall of the base plate; and an anti-loosening wire assembly and a tension detection assembly disposed on the base plate, the anti-loosening wire assembly being located above the tension detection assembly; wherein, the anti-loosening wire assembly includes: a stepper motor disposed on the other outer wall of the base plate; a rotating shaft fixed to the output end of the stepper motor; two elliptical plates symmetrically disposed on the outer wall of the rotating shaft; and a guide wheel rotating between the two elliptical plates; wherein, the tension detection assembly includes: a support plate disposed on one outer wall of the base plate; a pressure sensor disposed at the bottom of the support plate; a spring disposed at the bottom of the pressure sensor; a tension wheel bracket disposed at the bottom of the spring; a tension wheel rotating on the inner side wall of the tension wheel bracket; and a vertical rod disposed at the top center of the tension wheel bracket; and a rotating roller rotating on the outer wall of the base plate near the position between the anti-loosening wire assembly and the tension detection assembly.

[0007] Furthermore, the conductor wire extrusion assembly on the substrate near the guide wheel and the anti-loosening wire assembly includes: a second support plate disposed on the outer wall of one side of the substrate; an electric push rod disposed on the top of the second support plate; a second tension wheel bracket fixed to the output end of the electric push rod; and a second tension wheel rotating on the inner side wall of the second tension wheel bracket.

[0008] Furthermore, conductor wires are wound on the outer walls of the guide wheel, guide wheel, tension wheel one, rotating roller and tension wheel two.

[0009] Furthermore, the vertical rod passes through the support plate one;

[0010] By adopting the above technical solution, a pair of vertical rods on a support plate are used for limiting, ensuring that the vertical rods can be raised and lowered vertically.

[0011] Furthermore, the cross-sections of the guide wheel, tension wheel one, and tension wheel two are all I-shaped;

[0012] By adopting the above technical solution, the conductor wire can be limited by the "I"-shaped guide wheel, tension wheel one, and tension wheel two, ensuring the stability of conductor wire transportation and preventing the conductor wire transportation trajectory from deviating.

[0013] Furthermore, a total of several guide wheels are provided, and these guide wheels are arranged in an elliptical pattern between two elliptical plates;

[0014] By adopting the above technical solution, several guide wheels can ensure that the guide wheels and conductor wires are in full contact when the elliptical plate rotates.

[0015] The beneficial effects of this utility model are as follows:

[0016] This invention utilizes the elliptical trajectory movement of the guide wheel and adjusts the axial distance between the guide wheel and the rotating shaft. By changing the axial distance, the force on the conductor wire can be adjusted, thereby squeezing the conductor wire that has become less tensile or even loose due to the inertial rotation of the take-up reel, increasing the tension of the conductor wire, ensuring that the conductor wire is in the optimal tension state, and thus ensuring that the conductor wire is tightly wound in the subsequent winding and avoiding tangling.

[0017] By coordinating the anti-loosening wire assembly, the tension detection assembly, and the conductor wire extrusion assembly, the tension of the conductor wire before and after winding can be adjusted in real time to ensure that the conductor wire is always in a stable tension state and to ensure the normal production of the coil.

[0018] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention can be realized and obtained by means of the structures particularly pointed out in the description and the drawings. Attached Figure Description

The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] Reference Figure 1-4 This utility model embodiment proposes a coil auxiliary winding device for generator production, including a base plate 1. A guide wheel 2 is rotatably connected to one outer wall of the base plate 1, and a stepper motor 31 in the anti-loosening wire assembly 3 is fixedly connected to the other outer wall of the base plate 1 near the horizontal side of the guide wheel 2 by bolts. The stepper motor 31 is fixedly connected to a rotating shaft 32 through its output end. Two elliptical plates 33 are provided on the outer wall of the rotating shaft 32. A guide wheel 34 is rotatably connected between the two elliptical plates 33. A number of guide wheels 34 are provided, and the number of guide wheels 34 are elliptically distributed between the two elliptical plates 33. The number of guide wheels 34 can make the guide wheels 34 fully contact the conductor wire 7 when the elliptical plates 33 rotate.

[0027] A support plate 41 of the tension detection assembly 4 is provided on one outer wall of the substrate 1 near the guide wheel 2 and the guide wheel 34. A pressure sensor 42 is provided at the bottom of the support plate 41, and a spring 43 is provided at the bottom of the pressure sensor 42. A tension wheel bracket 44 is provided at the bottom end of the spring 43. A tension wheel 45 is rotatably connected to the inner side wall of the tension wheel bracket 44. A vertical rod 46 is provided at the top center of the tension wheel bracket 44. The vertical rod 46 passes through the support plate 41. The support plate 41 limits the vertical rod 46 to ensure that the vertical rod 46 rises and falls vertically.

[0028] Two rotating rollers 5 are rotatably connected on one side of the outer wall of the substrate 1, near the position between the anti-loosening line assembly 3 and the tension detection assembly 4.

[0029] On one side of the outer wall of the substrate 1, near the guide wheel 2 and the anti-loosening wire assembly 3, there is a support plate 61 of the conductor wire extrusion assembly 6. An electric push rod 62 is provided on the top of the support plate 61. The electric push rod 62 is fixedly connected to a tension wheel bracket 63 through its output end. A tension wheel 64 is rotatably connected to the inner side wall of the tension wheel bracket 63. The cross-sections of the guide wheel 34, tension wheel 45 and tension wheel 64 are all "I" shaped. Through the "I" shaped guide wheel 34, tension wheel 45 and tension wheel 64, the conductor wire 7 can be limited to ensure the stable conveying of the conductor wire 7 and avoid deviation of the conveying trajectory of the conductor wire 7.

[0030] Conductor wires 7 are wound on the outer walls of the guide wheel 2, guide wheel 34, tension wheel 1 45, rotating roller 5 and tension wheel 2 64.

[0031] The specific implementation method is as follows: When winding the generator coil, the conductor wire 7 is wound through the guide wheel 2, the guide wheel 34, the tension wheel 1 45, the rotating roller 5, and the tension wheel 2 64 (the winding shape trajectory is as shown in the attached instruction manual). Figure 1 As shown), when one end of the conductor wire 7 stops winding, the pay-off wheel (not shown in the figure) at the other end of the conductor wire 7 brakes and stops winding. Due to the inertia of the pay-off wheel, the pay-off wheel will rotate a certain amplitude. At this time, the conductor wire 7 is in a relaxed state, the tension wheel 64 is reduced, the tension wheel support 63 and the spring 43 are subjected to less upward pressure, and the pressure detected by the pressure sensor 42 is reduced. At this time, the stepper motor 31 is controlled to drive the rotating shaft 32 to rotate through its output end on one side. The elliptical plate 33 on the rotating shaft 32 rotates synchronously, and the guide wheel 34 moves in an elliptical trajectory. As the axial distance between the guide wheel 34 and the rotating shaft 32 changes, the guide wheel 34 squeezes the wound conductor wire 7 and adjusts the tension of the conductor wire 7 (since the two ends of the conductor wire 7 are in a limited state, when the conductor wire 7 is squeezed and stretched, the tension of the conductor wire 7 is adjusted).

[0032] When the wire is laid out, the conductor wheel 34 changes its axial position again. At this time, the electric push rod 62 drives the tension wheel bracket 63 to move downward through its output end on one side. The tension wheel 64 moves downward in sync. The tension wheel 64 squeezes the conductor wire 7, adjusts the squeezing force on the conductor wire 7 in real time, and uses the pressure sensor 42 to detect the tension of the conductor wire 7 in real time to ensure that the conductor wire 7 is always in a stable tension state and to ensure that the conductor wire 7 is tightly wound in the future.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
