Detailed implementation manners

[0042] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0043] In the present application, the hollow tube 700 includes but is not limited to the pins of European standard plugs.

[0044] See Figure 1 ,Figure 2 and Figure 5 a necking device for a hollow tube 700, comprising a frame 100;

[0045] a feeding mechanism 200 for moving the hollow tube 700 onto a material receiving mechanism 300;

[0046] a material receiving mechanism 300, the material receiving mechanism 300 comprising a rotary driving member 310 and a material receiving frame 320, the rotary driving member 310 being disposed on the frame 100, the material receiving frame 320 being connected to the rotary driving member 310, and a plurality of material receiving components 330 being evenly spaced around the material receiving frame 320 for receiving and locking the hollow tube 700;

[0047] a processing mechanism 400 surrounding the material receiving mechanism 300 for rotatably processing the hollow tube 700 on the material receiving component 330;

[0048] a controller for electrically connecting the feeding mechanism 200, the material receiving mechanism 300, and the processing mechanism 400.

[0049] In actual use, a large number of hollow tubes 700 are placed on the feeding mechanism 200, and the feeding mechanism 200 orderly moves the hollow tubes 700 one by one onto the material receiving components 330. Specifically, the rotary driving member 310 drives the material receiving frame 320 to rotate, and the material receiving components 330 on the material receiving frame 320 sequentially rotate to the positions corresponding to the feeding mechanism 200, so that the feeding mechanism 200 sequentially moves the hollow tubes 700 onto the material receiving components 330. During the rotation of the material receiving frame 320, the material receiving components 330 that receive the hollow tubes 700 continue to rotate to the corresponding positions of the processing mechanism 400, so that the processing mechanism 400 sequentially processes the hollow tubes 700, realizing both large - batch feeding and large - batch processing, and also realizing feeding while processing. The structural setting is ingenious, making the overall working steps compact and greatly improving the processing efficiency.

[0050] Supplementary description: The material receiving frame 320 is of a cylindrical structure, and a plurality of material receiving components 330 are evenly spaced on the side surface of the cylindrical material receiving frame 320. The material receiving components 330 can be set in one circle, can be set in two circles or multiple circles, and the processing mechanism 400 is also correspondingly set with an adapted number according to the number of circles. Therefore, the necking device of the present application can not only improve the efficiency by simultaneously receiving materials and processing, but also increase the number of materials processed simultaneously by increasing the number of circles of the material receiving components 330 to improve the efficiency. The diameter of the cylinder of the material receiving frame 320 also affects the number of material receiving components 330 in one circle. When the diameter of the cylinder of the material receiving frame 320 is larger, the number of material receiving components 330 in one circle is more. Therefore, the diameter of the cylinder of the material receiving frame 320 can also be set according to actual needs to flexibly set a reasonable efficiency.

[0051] It should be noted that the rotating drive member 310 is a rotating divider; there are multiple options for connecting the material receiving assembly 330 to the material receiving frame 320 to achieve a detachable connection between the two, such as using bolts; the controller is electrically connected to the rotating drive member 310, and the controller is used to control the operation of the rotating drive member 310.

[0054] In the above technical scheme, a large number of hollow tubes 700 are placed in the vibration plate 210. Under the action of the vibration plate 210, the hollow tubes 700 are arranged and output from the discharge pipe. At this time, the first movable driving member 240 drives the movable frame 260 to move so that the through hole 261 is aligned with the front of the discharge pipe. The hollow tube 700 is inserted into the through hole 261. The hollow tube 700 partially exceeds the through hole 261 and is placed in the auxiliary groove 231. The auxiliary groove 231 plays the role of receiving the hollow tube 700. The first movable driving member 240 then drives the movable frame 260 to move to the front position aligned with the second movable driving member 250. During this movement, the hollow tube 700 moves in the auxiliary groove 231. The second movable driving member 250 drives the first ejection shaft 270 to move to eject the hollow tube 700. The hollow tube 700 is pushed from the through hole 261 to the material receiving assembly 330, thereby completing the material transfer.

[0055] It should be noted that the first movable driving member 240 and the second movable driving member 250 are both cylinders; the controller is electrically connected to the vibration plate 210, the first movable driving member 240 and the second movable driving member 250, and the controller is used to control the operation of the vibration plate 210, the first movable driving member 240 and the second movable driving member 250.

[0056] In this embodiment, see Figure 5 ,Figure 6 and Figure 7 The material receiving assembly 330 includes a housing 340, a third moving drive 350, a linkage member 351, a clamping member 360, a locking member 370, and an ejecting member 380.

[0060] In the above technical solution, the hollow tube 700 is pushed into the clamping opening 361 by the second ejecting shaft. The hollow tube 700 presses against the second ejecting shaft 381, and the second ejecting shaft 381 is stressed to cause the spring 382 to contract and deform. The third moving drive 350 drives the locking member 370 to cover the clamping slit 362, that is, the locking member 370 locks the clamping slit 362 of the clamping member 360, and the clamping slit 362 closes, so that the clamping member 360 clamps the hollow tube 700, facilitating the processing mechanism 400 to perform operations such as processing and detecting the hollow tube 700; after operations such as processing and detecting are completed, the third moving drive 350 drives the locking member 370 to reset, that is, the clamping slit 362 is released, so that the clamping member 360 releases the hollow tube 700, and the spring 382 rebounds to eject the hollow tube 700, realizing automatic discharging.

[0061] It should be noted that the third moving drive 350 is a cylinder, and the controller is electrically connected to the third moving drive 350. The controller is used to control the operation of the third moving drive 350.

The first grinding assembly 410, the necking-down assembly 420, the second grinding assembly 430, and the flaring assembly 440 are sequentially arranged around the material receiving mechanism 300. That is, when the rotary driving member 310 drives the material receiving frame 320 to rotate, after the material receiving assembly 330 on the material receiving frame 320 sequentially receives the hollow tubes 700 from the feeding mechanism 200, it sequentially rotates to the corresponding positions of the first grinding assembly 410, the necking-down assembly 420, the second grinding assembly 430, and the flaring assembly 440, and thus grinding, necking-down, grinding, and flaring processes are sequentially performed. The surrounding arrangement facilitates simultaneous material receiving and processing.

[0063] In this embodiment, refer to Figure 9 , the first grinding assembly 410 includes a second bracket 411, a fourth moving driving member 412, and a first milling cutter 413.

The sleeve of the necking device 423 sleeves the hollow tube 700.
