Technical Field

[0001] This utility model relates to the field of enameled wire testing technology, and in particular to a device for testing the resilience performance of enameled wire. Background Technology

[0002] Enamelled wire is a major type of winding wire, consisting of a conductor and an insulation layer. The bare wire is annealed and softened, then coated with enamel multiple times and baked. After production, enamelled wire is usually wound into coils for storage and transportation. However, if the enamelled wire is too stiff, it will be difficult to wind into coils for storage and transportation; if it is too soft, it may break during winding. Therefore, before leaving the factory, the resilience of the enamelled wire needs to be tested to determine if its stiffness meets the requirements. Currently, however, there is a lack of a device for testing the resilience of enamelled wire. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a device for detecting the resilience of enameled wire, which can quickly measure the resilience of enameled wire and facilitate ensuring product quality.

[0008] In some embodiments of this utility model, a first limiting portion is formed by protruding from the inner wall of the guide hole, and a second limiting portion is formed by radially protruding from one end of the wire-blocking post away from the first limiting portion. A spring is sleeved on the wire-blocking post, and the two ends of the spring abut against the first limiting portion and the second limiting portion, respectively.

[0009] In some embodiments of this utility model, the driving assembly includes a second motor, a screw, a slide rail, a slider, and a movable block.

Detailed Implementation

[0021] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0022] Reference Figure 1 The enameled wire resilience testing device according to a first aspect of this utility model includes: a housing 110, a winding mechanism, and a dial 400; the housing 110 is transparent, and a mounting plate 120 and a drive assembly are disposed inside the housing 110, with the mounting plate 120 being vertically arranged; the winding mechanism is disposed on the mounting plate 120, and includes a wire-blocking post 310, a clamp, and a first motor, the drive assembly driving the wire-blocking post 310 to move, and the wire-blocking post 310 is perpendicular to the mounting plate 120; the clamp is used to lock the enameled wire, and the first motor drives the clamp to rotate in a vertical plane; the dial 400 is disposed on the mounting plate 120, and the dial 400, the wire-blocking post 310, and the clamp are arranged sequentially from top to bottom. By placing the clamp and drive assembly inside the housing 110, safety risks are reduced, and the transparent housing facilitates observation of the dial 400.

[0023] Reference Figure 5 After the enameled wire is produced, a certain length of enameled wire is cut and fixed to a fixture. Then, a first motor drives the fixture to rotate, causing the enameled wire to rotate. During rotation, the enameled wire comes into contact with the wire-stopping post 310 and winds itself onto the fixture. After the first motor drives the fixture to rotate a set number of turns, the enameled wire winds a certain number of times on the fixture. Then, the first motor stops operating. At this point, the enameled wire is still in contact with the wire-stopping post 310, and the enameled wire is still pointing to the initial reading on the dial 400. Then, the drive assembly drives the wire-stopping post 310 to separate from the enameled wire, and the enameled wire winds... After being wound onto the fixture, the enameled wire deforms. When the drive assembly removes the wire stop post 310, the enameled wire, due to its own elasticity, recovers its deformation and rotates around the fixture. After the enameled wire stops moving, the reading on the dial 400 is taken. The reading on the dial 400 is the angle. By reading the position of the enameled wire on the dial 400 and taking the corresponding value, the angle of rotation of the enameled wire can be obtained. The angle of the enameled wire's rebound reflects its resilience, thus providing a direct understanding of the wire's softness and hardness. This facilitates timely testing of the produced enameled wire and ensures stable production quality.

[0024] Reference Figure 2 It is understood that the clamp includes a cylinder 210 and a screw 220. The cylinder 210 has a positioning hole 211 radially. The screw 220 is threadedly connected to the cylinder 210 and extends axially into the positioning hole 211. The enameled wire is passed through the positioning hole 211, and then the screw 220 is rotated to move into the positioning hole 211. The screw 220 extends into the positioning hole 211 and abuts against the enameled wire. At the same time, by screwing the screw 220 into the positioning hole 211, the end of the screw 220 cooperates with the inner wall of the positioning hole 211 to clamp the enameled wire. This is simple and quick, achieving rapid locking of the enameled wire.

[0025] Reference Figure 2 It is understandable that the end of the screw 220 that extends into the positioning hole 211 is provided with rubber 221. When the screw 220 presses the enameled wire, the rubber 221 can increase the friction between the screw 220 and the enameled wire, and further lock the enameled wire on the clamp.

[0026] Reference Figure 1 It is understood that the mounting plate 120 has a guide hole 121 in the horizontal direction, and the wire-blocking post 310 is movably disposed in the guide hole 121. The drive assembly drives the wire-blocking post 310 to move in the horizontal direction. By driving the wire-blocking post 310 to move along the guide hole 121, the wire-blocking post 310 is retracted into the guide hole 121, thereby separating it from the enameled wire and avoiding interference with the movement of the enameled wire.

[0027] Reference Figure 3 Specifically, in the first embodiment, a first limiting part 122 protrudes from the inner wall of the guide hole 121, and a second limiting part 313 protrudes radially from one end of the wire-stopping post 310 away from the first limiting part 122. A spring 311 is sleeved on the wire-stopping post, and the two ends of the spring 311 abut against the first limiting part 122 and the second limiting part 313, respectively. The wire-stopping post 310 is driven to move by the driving component, causing it to extend out of the guide hole 121 and, by interfering with the enameled wire, to wind the enameled wire onto the clamp. When the driving component resets, the wire-stopping post 310 retracts into the wire hole under the drive of the spring 311, avoiding interference with the movement of the enameled wire, thus achieving automatic extension and retraction of the wire-stopping post 310, which is convenient and quick.

[0028] Reference Figure 3 It is understood that the drive assembly includes a second motor 321, a screw 322, a slide rail 323, a slider 324, and a movable block 325. The slide rail 323 and the slider 324 are slidably connected, the screw 322 is parallel to the slide rail 323, and the screw 322 is threadedly connected to the slider 324. The second motor 321 drives the screw 322 to rotate. The movable block 325 is mounted on the slider 324, and the movable block 325 drives the line-stopping post 310 to move axially along the guide hole 121. Through the cooperation of the slide rail 323, the slider 324, and the screw 322, the rotational motion of the second motor 321 is converted into linear motion, realizing the rapid movement of the movable block 325 and improving the movement efficiency of the line-stopping post 310. At the same time, in conjunction with the slider 324 and the slide rail 323, the straightness of the movement of the movable block 325 is improved.

[0029] Reference Figure 3 It is understandable that the movable block 325 is provided with a guide slope 326 on the side that abuts against the wire stop post 310, and the end of the wire stop post 310 away from the dial 400 is provided with an arc portion 312, which abuts against the guide slope 326. Spring 311 keeps guide ramp 326 in contact with arc portion 312. Drive assembly drives movable block 325 to move radially along guide hole 121. Arc portion 312 moves along guide ramp 326, causing wire stop post 310 to gradually move axially along guide hole 121 and extend out of guide hole 121. In addition, when drive assembly drives movable block 325 to reset, spring 311 drives wire stop post 310, keeping arc portion 312 in contact with wire ramp. Arc portion 312 moves along guide ramp 326. Spring 311 drives wire stop post 310 to move axially inward along guide hole 121, separating wire stop post 310 from enameled wire, avoiding interference with the movement of enameled wire. The structure is simple and easy to maintain.

[0030] Reference Figure 4It is also understood that in the second embodiment, the inner wall of the guide hole 121 is provided with a guide groove 123 along the axial direction, the wire-blocking post 310 protrudes to form a guide block 314, the guide block 314 matches the guide groove 123, the guide block 314 is slidably disposed in the guide groove 123, and the driving component drives the wire-blocking post 310 to move along the guide groove 123.

[0031] Reference Figure 4 Specifically, the drive assembly includes a third motor 331, a transmission component 333, and a connecting shaft 334. The third motor 331 drives the connecting shaft 334 to rotate through the transmission component 333. The wire-blocking post 310 has a threaded hole along its axial direction, and the other end of the connecting shaft 334 is threadedly connected to the threaded hole. One end of the third motor 331 is mounted on the mounting plate 120, and the other end of the third motor 331 is mounted on a positioning plate 332. The transmission component 333 is mounted on the positioning plate 332, and the connecting shaft 334 is rotatably mounted on the positioning plate 332. The third motor 331 drives the connecting shaft 334 to rotate through the transmission component 333. The connecting shaft 334 cooperates with the guide block 314 to convert the rotational motion of the connecting shaft 334 into the linear motion of the wire-blocking post 310, realizing the rapid movement of the wire-blocking post 310 and enabling the wire-blocking post 310 to automatically move along the axis of the guide hole 121, thereby improving efficiency. It should be noted that the transmission component 333 can be a worm gear transmission component or a gear transmission component. In this embodiment, the transmission component 333 is a gear transmission component.

[0032] The detection method for the enameled wire resilience testing device applied to the first aspect embodiment of this utility model includes the following steps:

[0033] S1. Take a section of the enameled wire to be tested;

[0034] S2. Fix one end of the enameled wire to be tested on the fixture, and point the other end of the enameled wire to be tested to the starting scale on the scale 400, and make contact with the wire stop post 310.

[0035] S3. The first motor drives the fixture to rotate. After the enameled wire to be tested is blocked by the wire stop post 310, it is wound around the fixture a set number of times.

[0036] S4. The first motor stops rotating, the wire stop post 310 retracts, and the enameled wire to be tested rotates around the clamp under the action of the spring force;

[0037] S5. After the enameled wire to be tested stops rotating, read the scale at which the enameled wire stops on the dial 400 to obtain the springback angle of the enameled wire.

[0038] This utility model discloses a device and method for detecting the resilience of enameled wire. The device fixes the enameled wire sample to be tested onto a fixture. A first motor drives the fixture to rotate. With the help of a wire-stopping post 310, as the fixture rotates, the enameled wire contacts the post 310 and winds onto the fixture. The fixture rotates a predetermined number of turns and then stops, allowing part of the enameled wire to be wound onto the fixture. The drive assembly then separates the wire-stopping post 310 from the enameled wire. The enameled wire rebounds under its own resilience force and rotates at a certain angle. After the enameled wire stops moving, the rotation angle is obtained by reading the corresponding value on the scale 400, thus detecting the resilience of the sample and determining the hardness of the enameled wire. This method is convenient, quick, and efficient, allowing for timely detection of product quality and ensuring production.
