[0027] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0028] Reference Figure 1 , Figure 1 The schematic diagram of the structure of the plug assembly involved in one embodiment of the utility model is shown. The mark a shows the plug, and the mark b shows the plug sleeve. In other embodiments, the plug assembly can be in other shapes.

[0029] Reference Figure 2 The multi-station pin assembly plug-in and pull-out cycle device in one embodiment of the utility model comprises a first fixed block 1, a second fixed block 2 and a driving assembly 3. The first fixed block 1 is provided with a plurality of first limiting parts for limiting and fixing the pins. The second fixed block 2 is provided with a plurality of second limiting parts for limiting and fixing the socket, and the first limiting parts correspond to the second limiting parts in height and position. The driving assembly 3 can be controlled to drive and change the distance between the first fixed block 1 and the second fixed block 2 so that the pins can be inserted into or pulled out of the socket.

[0030] Combination Figure 1 and Figure 2 When performing a plug-in and pull-out test on a pin assembly, first fix multiple pins at different first limit portions in the first fixed block 1, then fix multiple plug sleeves at different second limit portions in the second fixed block 2, and finally start the driving assembly 3 to effectively drive the first fixed block 1 and the second fixed block 2 to move, thereby being able to perform a plug-in and pull-out test on multiple pin assemblies at one time, effectively improving the test efficiency and shortening the test cycle.

[0031] In this embodiment, the driving component 3 drives the first fixed block 1 to approach or move away from the second fixed block 2. In other embodiments, the driving component 3 can also drive the second fixed block 2 to approach or move away from the first fixed block 1; it can also drive the first fixed block 1 and the second fixed block 2 to approach or move away from each other.

[0032] Reference Figure 3 and Figure 4 The first fixing block 1 includes an upper pressing block 11 and a lower pressing block 12 which are detachably connected. The abutting surfaces of the upper pressing block 11 and the lower pressing block 12 are provided with a plurality of concave surfaces 13. The plurality of concave surfaces 13 are the first limiting parts mentioned above. When the upper pressing block 11 and the lower pressing block 12 are covered, a plurality of limiting grooves are formed between the concave surfaces 13. In this embodiment, a first fixing block 1 is provided with five limiting grooves. In other embodiments, the number of limiting grooves can be other numbers of at least two.

[0033] Specifically, when fixing the pin in the first fixing block 1, first move the upper pressing block 11 and the lower pressing block 12 away from each other, then place the pin in the limiting groove, and finally cover and fix the upper pressing block 11 and the lower pressing block 12 to complete the limiting fixation of the pin, which can be fixed by screws or other methods. The above installation and fixing method improves the convenience of pin installation.

[0034] In this embodiment, the structure of the second fixing block 2 is similar to that of the first fixing block 1 , and the way the second fixing block 2 positions and fixes the plug sleeve is the same as the way the first fixing block 1 positions and fixes the plug pin.

[0035] It can be understood that the shape and size of the concave surface 13 of the first fixing block 1 can be specifically set according to the shapes of different types of pins. Therefore, the multi-station pin assembly plug-in and pull-out circulation device of the present application can limit and fix a variety of different types of pins, thereby improving the adaptability of the device to different types of pins.

[0036] Further, in order to improve the fixing effect of the pin, refer to Figure 4 , the abutting surface of the upper pressing block 11 and / or the lower pressing block 12 is provided with a limiting rod 14 adapted to the shape of the plug pin. In this embodiment, the limiting rod 14 is fixedly installed on a side of the lower pressing block 12 close to the upper pressing block 11, and the plug pin is provided with an avoidance hole, and the limiting rod 14 is inserted into the avoidance hole to further fix the plug pin. In other embodiments, the limiting rod 14 can also be fixedly installed on a side of the upper pressing block 11 close to the lower pressing block 12, or both the upper pressing block 11 and the lower pressing block 12 are provided with limiting rods 14.

[0037] Reference Figure 2 In this embodiment, the multi-station pin assembly plug-in and pull-out cycle device further includes a connecting plate 4, a plurality of first fixing blocks 1 are provided, and the plurality of first fixing blocks 1 are sequentially arranged and fixed on a side surface of the connecting plate 4, and the driving component 3 drives the connecting plate 4 to move. The setting of the connecting plate 4 facilitates the simultaneous fixed connection of the plurality of first fixing blocks 1, thereby further increasing the number of tests on the plug-in assembly to shorten the test cycle.

[0038] Among them, it is understandable that Figure 4 Each first fixing block 1 can be individually set with a concave surface 13 according to the shape of different types of plug-in parts. Different arrangements and combinations of different first fixing blocks 1 on the connecting plate 4 can perform plug-in tests on multiple groups of different plug-in parts, further improving the test efficiency of the plug-in parts.

[0039] Further, in order to improve the stability of the movement of the connecting plate 4, refer to Figure 2 The multi-station pin assembly plug-in and pull-out cycle device of this embodiment also includes a slider 5 and a slide rail 6. The slider 5 is fixed to a side surface of the connecting plate 4 away from the first fixed block 1; the slide rail 6 is located on a side of the slider 5 away from the connecting plate 4 and is slidably connected to the slider 5.

[0040] Therefore, the driving assembly 3 can drive the connecting plate 4 to move smoothly, thereby making the first fixing block 1 move smoothly, thereby effectively improving the effect of the plug-in test.

[0041] Reference Figure 2 and Figure 5 The driving assembly 3 includes a driving member 31, a transmission member 32 and a mounting seat 33. The output end of the driving member 31 is fixedly connected to the transmission member 32, the transmission member 32 is transmission-connected to the connecting plate 4, and the mounting seat 33 is used for mounting the driving member 31 and the transmission member 32.

[0042] Specifically, refer to Figure 2 and Figure 5 The driving member 31 is provided with a rotating shaft. In this embodiment, the driving member 31 can be a rotating servo motor. The driving member 31 is fixedly mounted on one side of the mounting seat 33.

[0043] The transmission member 32 includes a screw rod 321 and a guide rod 322. The rotating shaft of the driving member 31 is fixedly connected to one end of the screw rod 321, the screw rod 321 is threadedly connected to the connecting plate 4 (the thread is not shown in the figure), and the screw rod 321 is also rotatably connected to the mounting seat 33. Both ends of the guide rod 322 are fixedly connected to the mounting seat 33, and the guide rod 322 is slidably connected to the connecting plate 4, and the guide rod 322 is parallel to the side of the screw rod 321.

[0044] In this embodiment, refer to Figure 2 and Figure 5 A protrusion 41 is provided below the connecting plate 4. The protrusion 41 is provided with a through hole for the guide rod 322 to pass through. The guide rod 322 is slidably connected to the connecting plate 4 through the through hole. In this embodiment, two guide rods 322 are provided. In other embodiments, the guide rods 322 may also be other numbers, such as one or three. The provision of the guide rod 322 can limit the moving direction of the connecting plate 4, thereby ensuring that the pin is effectively aligned with the plug sleeve, reducing the possibility that the poor plugging accuracy of the pin may cause uneven wear and affect the final test accuracy.

[0045] In other embodiments, the protrusion 41 may not be provided, and the transmission connection between the connecting plate 4 and the transmission member 32 may be achieved by increasing the thickness of the connecting plate 4 .

[0046] When the driving assembly 3 is running, the driving member 31 drives the screw rod 321 to rotate alternately clockwise and counterclockwise, and the screw rod 321 drives the connecting plate 4 to move toward or away from the second fixed block 2, so that the pin is inserted into or pulled out of the socket to complete the plug-in and pull-out test of the pin assembly.

[0047] It can be understood that the speed adjustment of the rotating shaft of the driving member 31 can effectively simulate the speed of the plug pin being inserted into or pulled out of the socket, further improving the accuracy of the plug-in test.

[0048] Reference Figure 2 In this embodiment, the multi-station pin assembly plugging and unplugging cycle device also includes a controller 7 and an electronic counter (not shown in the figure). The controller 7 is electrically connected to the drive component 3 and the electronic counter respectively. The electronic counter is used to monitor and obtain the number of plugging and unplugging times of the pin when the controller 7 controls the drive component 3.

[0049] In this embodiment, refer to Figure 2 and Figure 5The controller 7 is electrically connected to the driving member 31. The controller 7 controls the rotation speed and direction of the driving member 31 to effectively simulate the plugging and unplugging process of the plug pin and the plug socket. The electronic counter can monitor the number of plugging and unplugging times. Therefore, the performance data of the plug assembly sample can be obtained after the specified number of plugging and unplugging times.

[0050] The implementation principle of this embodiment is as follows: the controller 7 controls the driving assembly 3 to drive the first fixed block 1 and the second fixed block 2 to move closer to or farther from each other to complete the plug-in and pull-out test of the plug-in assembly. The electronic counter monitors the number of plug-in and pull-out times, so that the plug-in and pull-out assembly completes the test within the specified number of plug-in and pull-out times to achieve quality inspection of the plug-in and pull-out assembly. The first fixed block 1 and the second fixed block 2 can be specifically set according to the number and shape of the plug-in and pull-out assembly, so as to meet the requirements of efficient testing of multiple numbers and models of plug-in and pull-out assemblies, shorten the test cycle, and reduce the test cost.
