Detailed Embodiments

[0027] The specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0028] Referring to Figure 1 , the enameled wire resilience performance detection device according to the embodiment of the first aspect of the present invention includes: a base 110, a winding mechanism, and a dial 400; the base 110 is provided with a mounting plate 120 and a driving component, and the mounting plate 120 is vertically arranged; the winding mechanism is arranged on the mounting plate 120, and the winding mechanism includes a wire blocking post 310, a clamp, and a first motor. The driving component drives 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 arranged on the mounting plate 120, and the dial 400, the wire blocking post 310, and the clamp are arranged in sequence from top to bottom.

[0029] Referring to Figure 5 , after the enameled wire is produced, a certain length of the enameled wire is intercepted and fixed on the clamp. Then the first motor drives the clamp to rotate, and the clamp drives the enameled wire to rotate. During the rotation of the enameled wire, the enameled wire abuts against the wire blocking post 310, and then the enameled wire winds around the clamp. After the first motor drives the clamp to rotate a set number of turns, the enameled wire winds around the clamp for a certain number of turns. Then the first motor stops operating. At this time, the enameled wire still remains in contact with the wire blocking post 310, and at this time, the enameled wire also points to the initial reading of the dial 400. Then the driving component drives the wire blocking post 310 to separate from the enameled wire. After the enameled wire winds around the clamp, the enameled wire deforms. After the driving component drives the wire blocking post 310 to withdraw, the enameled wire will recover its deformation due to its own elasticity and rotate around the clamp. After the enameled wire stops moving, the reading of the enameled wire on the dial 400. The reading on the dial 400 is an angle. By reading the position of the enameled wire on the dial 400 and reading the corresponding value, the angle of rotation of the enameled wire is obtained. The resilience performance of the enameled wire is reflected by the angle of resilience of the enameled wire, so that the hardness and softness of the enameled wire can be intuitively understood, which is convenient for timely detecting the produced enameled wire and ensuring the stability of the production quality.

[0030] Referring to Figure 2, it can be understood that the fixture includes a cylinder 210 and a screw 220. The cylinder 210 is radially provided with a positioning hole 211. The screw 220 is threadedly connected to the cylinder 210, and the screw 220 extends axially into the positioning hole 211. Pass the enameled wire through the positioning hole 211, and then by rotating the screw 220, the screw 220 moves towards 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, which is simple and fast, and realizes the quick locking of the enameled wire.

[0031] Refer to Figure 2 , it can be understood that a rubber 221 is provided at one end of the screw 220 extending into the positioning hole 211. 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 fixture.

[0032] Refer to Figure 1 , it can be understood that the mounting plate 120 is horizontally provided with a guiding hole 121. The wire blocking post 310 is movably arranged in the guiding hole 121, and the driving component drives the wire blocking post 310 to move horizontally. By driving the wire blocking post 310 to move along the guiding hole 121 by the driving component, the wire blocking post 310 is retracted into the guiding hole 121, so as to separate from the enameled wire and avoid interfering with the movement of the enameled wire.

A second limiting portion 313 is formed by protruding radially from one end of the wire blocking post 310 away from the first limiting portion 122. A spring 311 is sleeved on the wire blocking post 310, and both ends of the spring 311 abut against the first limiting portion 122 and the second limiting portion 313 respectively. By driving the wire blocking post 310 to move by the driving component, the wire blocking post 310 extends out of the guiding hole 121, and by interfering with the enameled wire, the enameled wire is wound on the fixture; when the driving component resets, the wire blocking post 310 retracts into the guiding hole under the driving of the spring 311, avoiding interfering with the movement of the enameled wire, and realizing the automatic expansion and contraction of the wire blocking post 310, which is convenient and fast.

[0034] Refer to Figure 3, It can be understood that the driving 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 is slidably connected to the slider 324. The screw 322 is parallel to the slide rail 323. The screw 322 is threadedly connected to the slider 324.

The movable block 325 is arranged on the slider 324, and the movable block 325 drives the wire blocking column 310 to move along the axial direction of the guiding 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 a linear motion, realizing the rapid movement of the movable block 325, improving the movement efficiency of the wire blocking column 310, and at the same time, cooperating with the slider 324 and the slide rail 323 to improve the straightness of the movement of the movable block 325.

The arc portion 312 is in contact with the guiding inclined surface 326. The guiding inclined surface 326 and the arc portion 312 are kept in contact through the spring 311. The driving assembly drives the movable block 325 to move along the radial direction of the guiding hole 121, and the arc portion 312 moves along the guiding inclined surface 326, so that the wire blocking column 310 gradually moves along the axial direction of the guiding hole 121 and extends out of the guiding hole 121; in addition, when the driving assembly drives the movable block 325 to reset, the spring 311 drives the wire blocking column 310, so that the arc portion 312 is in contact with the guiding inclined surface, the arc portion 312 moves along the guiding inclined surface 326, and the spring 311 drives the wire blocking column 310 to move axially inward along the guiding hole 121, so that the wire blocking column 310 is separated from the enameled wire, avoiding interfering with the movement of the enameled wire. The structure is simple and convenient for maintenance.

The third motor 331 drives the connecting shaft 334 to rotate through the transmission component 333. The connecting shaft 334 cooperates with the guiding 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, enabling the wire blocking post 310 to automatically move along the axis of the guiding hole 121, and improving the efficiency. It should be noted that the transmission component 333 can be a worm transmission component or a gear transmission component.
