Technical Field

[0001] The utility model relates to the technical field of springback angles, in particular to a high-precision springback angle detector for enameled wire production. Background Art

[0002] Enameled wire is widely used in industry and is a must for making various electronic devices. After the enameled wire is produced, it is necessary to conduct a rebound test on the enameled wire to detect its anti-deformation ability. The rebound angle detector is a professional instrument used to detect the rebound performance of enameled wire. It is easy to operate, small in size and highly sensitive.

[0003] During the test, the enameled wire sample needs to be wound on a winding rod. After the test, it is difficult for the staff to remove the enameled wire from the winding rod because the enameled wire is wound too tightly and has a certain hardness. During the removal process, the fingers use a lot of force, which can easily cause damage to the staff's hands. In view of this, we propose a high-precision rebound angle detector for enameled wire production. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-Figure 5 , a technical solution provided by the utility model:

[0025] A high-precision rebound angle detector for enameled wire production includes a detector body 1, on which a rotating shaft 2 is rotatably mounted, and a winding component 3 is provided on the rotating shaft 2 for winding the enameled wire to be tested. A driving motor 5 is provided in the detector body 1, and one end of the rotating shaft 2 is fixed to the output shaft of the driving motor 5. An optical fiber sensor is provided on the detector body 1. During testing, the enameled wire is firstly wound on the winding component 3, and the rotating shaft 2 is driven to rotate by the output shaft of the driving motor 5, thereby driving the winding component 3 and the enameled wire wound thereon to rotate, and the rebound elasticity of the enameled wire is tested by the optical fiber sensor.

[0026] The conventional winding rod is a rigid cylindrical structure. When the enameled wire is tightly wound on the winding rod, it is not easy to remove it from the winding rod after inspection.

[0027] To this end, the winding component 3 in this embodiment includes a plurality of arc plates 301, which are distributed in a circular array outside the rotating shaft 2, so that the winding rod is multi-petal-shaped. A guide rod 302 is slidably connected to the inner wall of the arc plate 301, and the guide rod 302 extends along the diameter direction of the rotating shaft 2, and one end of the guide rod 302 passes through the arc plate 301 and is fixed on the outer circumference of the rotating shaft 2. The guide rod 302 is used to guide the arc plate 301, so that the arc plate 301 can only move along the diameter direction of the rotating shaft 2. The guide rod 302 is set on the axis of the arc plate 301. When the arc plate 301 moves along the length direction of the guide rod 302, the distance between it and the left and right arc plates 301 can be changed at the same time. When the plurality of arc plates 301 shrink together toward the rotating shaft 2, the diameter of the winding rod can be reduced, so that the enameled wire can be quickly detached from the winding rod.

[0028] Furthermore, three guide rods 302 are arranged on each arc plate 301, and the three guide rods 302 are arranged at equal distances in a straight line to improve the stability of the arc plate 301. A return spring 303 is fixed to one end of each guide rod 302 away from the rotating shaft 2, and one end of the return spring 303 away from the guide rod 302 is fixed to the inner wall of the arc plate 301. After the detection is completed, the elastic force of the return spring 303 can drive the arc plate 301 to reset, so that the multiple arc plates 301 can quickly shrink inwards, so that the diameter of the winding rod is reduced.

[0029] In order to prevent the arc plate 301 from moving randomly during the winding and detection process, a limiting component 4 is provided on the rotating shaft 2, and the limiting component 4 is used to limit the relative movement between the arc plate 301 and the rotating shaft 2, so as to ensure the stability of the winding component 3.

[0030] Specifically, the limiting component 4 in this embodiment includes a plurality of limiting plates 401, and the number of the limiting plates 401 is the same as the number of the arc plates 301, and each limiting plate 401 is located between two adjacent arc plates 301, thereby limiting the distance between the two arc plates 301, so that the arc plates 301 can no longer move toward the direction of the rotating shaft 2. During the winding and testing process, the winding rod can maintain a fixed diameter.

[0031] It is worth noting that a plurality of slide grooves 201 are provided on the rotating shaft 2, in which a plurality of limit plates 401 slide respectively. After the limit plate 401 slides along the slide groove 201 for a certain distance, it will completely detach from the arc plate 301. At this time, the arc plate 301 loses the restriction of the external force and will shrink rapidly under the elastic force of the reset spring 303, so that the diameter of the winding rod is reduced, and the enameled wire can be quickly detached from the arc plate 301. A chamfer is provided on one end of the arc plate 301 close to the limit plate 401, so as to change the direction of force transmission. When the limit plate 401 moves in the opposite direction in the slide groove 201, it can push the arc plate 301 through the chamfer, so that the arc plate 301 automatically opens outward.

[0032] In addition, the limiting component 4 also includes a supporting spring 403, one end of which is fixed to the inner wall of the rotating shaft 2, and a connecting block 402 is fixed to the other end of the supporting spring 403, and multiple limiting plates 401 are fixed on the connecting block 402, so that the multiple limiting plates 401 can move synchronously, and then the multiple arc plates 301 can open outward synchronously, thereby improving the operating efficiency.

[0033] The working principle of the utility model is as follows: before testing the rebound angle of the enameled wire, the enameled wire sample is firstly wound on the outer surface of the multi-petal winding rod composed of a plurality of arc-shaped plates 301, and one end of the sample is extended into the optical fiber sensor. Then the driving motor 5 is started, and the driving motor 5 drives the winding component 3 to rotate through the rotating shaft 2 to perform the rebound test.

[0034] After the test, the enameled wire sample needs to be removed from the winding component 3. At this time, push the limit plate 401 to one side of the detector body 1. When the limit plate 401 is separated from the arc plate 301, the arc plate 301 will move closer to the direction of the rotating shaft 2 under the elastic force of the reset spring 303, thereby reducing the outer diameter of the winding component 3. The winding component 3 is no longer in close contact with the enameled wire, so the entire enameled wire roll can be easily and quickly removed from the device. After the wire roll is removed, loosen the limit plate 401. At this time, the connecting block 402 and the limit plate 401 will automatically reset under the elastic force of the support spring 403, and the limit plate 401 will re-enter between the two arc plates 301. During the entry process, the limit plate 401 pushes the arc plate 301 by chamfering, so that the arc plate 301 automatically opens outward, which is convenient for testing the next enameled wire sample.
