By rotating the adjusting threaded rod 4, the trapezoidal slide 7 is made to slide in the T-shaped fixing block 2. When the trapezoidal slide 7 releases the restrictions of the two sliding rods 9, the reaction force of the return springs 8 on the two sliding rods 9 slides the two limit blocks 3 into the T-shaped fixing block 2, releasing the restrictions of the T-shaped fixing block 2 in the mounting frame 5, and then the eccentricity detection device body 1 is lifted up, and the eccentricity detection device body 1 is disassembled for maintenance. This structure is simple and easy to operate, which improves the maintenance efficiency of the eccentricity detection device body 1.

[0022] like Figure 3 As shown, a guide bar 20 is fixedly connected to the inner wall of the T-shaped fixing block 2, and one side of the guide bar 20 is slidably connected to the outer wall of the trapezoidal slide 7. The guide bar 20 can limit the sliding direction of the trapezoidal slide 7.

[0023] like Figure 1 and Figure 2 As shown, a support frame 11 is provided on one side of the eccentricity detection device body 1, a sliding track 13 is fixedly connected to one side of the support frame 11, a driving device 12 is fixedly connected to the other side of the support frame 11, an output end of the driving device 12 is transmission-connected to a driving threaded rod 19, an outer side wall of the driving threaded rod 19 is threadedly connected to a sliding table 15, one side of the sliding table 15 is fixedly connected to one side of the mounting frame 5, by turning on the driving device 12, the sliding table 15 slides in the sliding track 13, and the position of the eccentricity detection device body 1 is adjusted, so as to facilitate the detection of another enameled wire and improve the detection efficiency.

[0024] like Figure 1 As shown, a guide rod 14 is fixedly connected to the middle of one side of the support frame 11, and the outer surface of the guide rod 14 is slidably connected to one side of the sliding platform 15.

The guide wheel 18 can guide the enameled wire to prevent the enameled wire from being entangled and affecting the detection efficiency.

[0026] like Figure 2 and Figure 4 As shown, a buffer box 16 is fixedly installed on the inner wall of the sliding table 15, a mounting groove 23 is opened on one side of the interior of the buffer box 16, a sliding block 25 is slidably connected to the inner wall of the mounting groove 23, a sliding column 26 is fixedly connected to one side of the sliding block 25, a sliding rod 24 is fixedly connected to the lower end of the sliding block 25, a return spring 27 is sleeved on the outer surface of the sliding rod 24, one end of the return spring 27 is fixedly connected to one side of the inner wall of the mounting groove 23, a buffer plate 21 is provided on one side of the sliding block 25, a special-shaped groove 22 is opened through one side of the buffer plate 21, and the inner wall of the special-shaped groove 22 is connected to the sliding column 26.

Through the structural design of the reset spring 27 and the buffer plate 21, when the side of the sliding table 15 collides, the buffer plate 21 will slide inside the buffer box 16. In the process of the buffer plate 21 sliding inside the buffer box 16, the inner wall of the special-shaped groove 22 will squeeze the sliding column 26, and the squeezing force will be offset by the reaction force of the reset spring 27, thereby preventing the sliding table 15 from moving too fast. The sliding table 15 will hit the support frame 11, causing damage to the electronic components in the eccentricity detection device body 1.

[0027] The utility model provides an eccentricity detection device for enameled wire, and the specific working principle is as follows:

[0028] When the paint film of the enameled wire is tested for eccentricity, the enameled wire is first passed through the guide wheel 18 on the support frame 11, and then the eccentricity detection device body 1 is turned on. The eccentricity detection device body 1 detects the enameled wire. During the detection, another enameled wire to be tested can be passed through another guide wheel 18. When the detection of the first enameled wire is completed, the drive device 12 is turned on to move the sliding table 15 to the position of another enameled wire for detection. The above operation is repeated for detection. When the sliding table 15 moves to the inner wall of the support frame 11 and its moving speed is too fast, when the side of the sliding table 15 collides, the buffer plate 21 will slide inside the buffer box 16. During the sliding process of the buffer plate 21 inside the buffer box 16, the inner wall of the special-shaped groove 22 will impact the sliding column 26. The extrusion force is offset by the reaction force of the reset spring 27. When the eccentricity detection device body 1 is used for a long time, the eccentricity detection device body 1 is damaged. The adjusting threaded rod 4 is rotated to make the trapezoidal slide 7 slide in the T-shaped fixed block 2. When the trapezoidal slide 7 releases the restriction of the two slide bars 9, the reaction force of the reset spring 8 on the two slide bars 9 slides the two limit blocks 3 into the T-shaped fixed block 2, releasing the restriction of the T-shaped fixed block 2 in the mounting frame 5. Then the eccentricity detection device body 1 is lifted up, the eccentricity detection device body 1 is disassembled for maintenance, and then the T-shaped fixed block 2 of the new equipment is slid into the mounting frame 5. The adjusting threaded rod 4 on the T-shaped fixed block 2 is rotated in the opposite direction, thereby fixing the eccentricity detection device body 1 in the mounting frame 5.

[0029] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
