DETAILED DESCRIPTION

[0026] In order to make the objects, features and advantages of the present application more obvious and understandable, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0027] Reference Figure 1-6, shows a structural schematic diagram of an automatic pin orientation selection mechanism, which may specifically include: a rotation drive unit 1 and a positioning fixture 2, wherein the rotation drive unit 1 is connected to the positioning fixture 2 and is used to drive the positioning fixture 2 to rotate; a positioning hole 211 is opened at the center of the positioning fixture 2, and the positioning hole 211 is half-moon-shaped, and the positioning hole 211 is adapted to the cut surface of the pin 7.

[0028] In the embodiment of the present application, the rotary drive unit 1 and the positioning fixture 2 are connected, and are used to drive the positioning fixture 2 to rotate; a positioning hole 211 is provided at the center of the positioning fixture 2, and the positioning hole 211 is half-moon-shaped, and the positioning hole 211 is adapted to the cut surface of the pin 7. The cut surface of the PIN pin can be accurately located by the half-moon-shaped positioning hole 211 of the positioning fixture 2, and the automatic orientation of the PIN pin can be realized by driving the positioning fixture 2 to rotate by the rotary drive unit 1. The present application solves the problem of accurate orientation of the PIN pin solder cup during the process of automatic pin insertion 7 of the aviation joint connector, and the PIN pin is selected and fixed by the PIN pin orientation mechanism to realize automatic and accurate orientation of the pin 7; the automatic steering mechanism is fool-proof in design, and the cut surface of the PIN pin is accurately located to realize PIN orientation.

[0029] Next, an automatic pin 7 direction selection mechanism in this exemplary embodiment will be further described.

[0030] In one embodiment of the present application, the rotation drive unit 1 includes a driving cylinder 11, a rack 12 and a gear 13, one end of the rack 12 is connected to the driving cylinder 11, the gear 13 is meshed with one side of the rack 12, and the positioning fixture 2 is arranged above the gear 13 and connected to the central axis of the gear 13. The driving cylinder 11 drives the rack 12 to reciprocate in the horizontal direction, and the rack 12 drives the gear 13 to rotate back and forth, so that the gear 13 drives the positioning fixture 2 to rotate back and forth, realizing automatic orientation selection of the pin 7.

[0031] In one embodiment of the present application, the positioning fixture 2 includes a plug-in rod 21, and the positioning hole 211 is opened at the top of the plug-in rod 21. The positioning hole 211 is semi-lunar in shape and is adapted to the cut surface of the plug pin 7 for locating the direction of the plug pin 7. When the rotation drive unit 1 drives the plug-in rod 21 to rotate, the plug pin 7 is pressed down by the downward pressing structure above and embedded in the plug-in rod 21. The semi-lunar positioning hole 211 matches the PIN pin to achieve fixed orientation of the pin and the fixture.

[0032] As an example, the positioning fixture 2 also includes a connecting block 22, a spring 23, a positioning column 24 and a stopper. The connecting block 22 is connected to the central axis of the gear 13. The positioning column 24 is arranged above the connecting block 22 and on the central axis of the gear 13. The spring 23 is connected between the positioning column 24 and the connecting block 22. A connecting hole is provided at the bottom of the plug rod 21, and the positioning column 24 is inserted into the connecting hole. Through the adaption connection between the positioning column 24 and the connecting hole, the plug rod 21 is connected to the connecting block 22, and the connecting block 22 can drive the plug rod 21 to rotate synchronously. By arranging a spring 23 at the bottom of the plug rod 21, the plug rod 21 can move up and down.

[0033] The stopper is fixedly connected to the edge of the connecting block 22, and is in the shape of a long strip, and the axial direction of the stopper is parallel to the axial direction of the positioning column 24, and the top of the stopper is higher than the top of the positioning column 24; the side wall of the plug rod 21 is provided with a limit groove 212, and the stopper is inserted into the limit groove 212. By setting the stopper, the plug rod 21 can be guided and limited. When the reciprocating motion of the rack 12 stops, the plug rod 21 is prevented from rotating, so that the position and angle direction of the fixture are fixed and unchanged, and accurate positioning is achieved.

[0034] Furthermore, two limiters are provided, and the two limiters are relatively connected to the edge of the connecting block 22, and the limiters are in a rectangular strip structure, and the limit slot 212 is a rectangular slot adapted to the limiter. By relatively arranging the two limiters and arranging them in a rectangular structure, the limiting stability of the plug rod 21 can be improved.

[0035] As an example, a fixing seat 3 is also included, the fixing seat 3 is arranged on one side of the rack 12, a groove 31 is provided on the side of the fixing seat 3 close to the rack 12, the gear 13 is rotatably connected in the groove 31, the rack 12 is passed through the groove 31 and meshes with the gear 13; a first through hole 32 connected to the groove 31 is provided on the top of the fixing seat 3, and the positioning fixture 2 is passed through the first through hole 32. By providing the fixing seat 3, the gear 13 is supported, the rack 12 is limited, and it is contained inside, so as to improve the stability and compactness of the mechanism and improve the aesthetics.

[0036] As an example, a cover plate 4 is provided on the top of the fixing seat 3, and the cover plate 4 is provided with a second through hole, and the second through hole is connected to the first through hole 32; a limiting sleeve 41 is fixedly connected to the top of the second through hole, and the limiting sleeve 41 is sleeved on the outside of the plug-in rod 21 and has a rotation gap with the plug-in rod 21, and the top of the limiting sleeve 41 is higher than the top of the plug-in rod 21; a limiting hole 411 is provided on the top of the limiting sleeve 41, and the limiting hole 411 is connected to the positioning hole 211, and the aperture of the limiting hole 411 is adapted to the outer diameter of the plug pin 7. It should be noted that, at one end, when the PIN needle is pressed down and its cut surface matches the plug-in rod 21, one end of the PIN needle is fixed by the plug-in rod 21, while the other end has a certain length and has no support, resulting in poor stability. By setting a limiting sleeve 41 higher than the plug-in rod 21 to sleeve it inside, and opening a limiting hole 411, during the process of the PIN needle being pressed down, on the one hand, it can play a limiting role so that it can be accurately matched with the semi-lunar positioning hole 211. On the other hand, the contact area between the limiting sleeve 41 and the PIN needle is increased, which can support it, thereby improving the positioning accuracy and stability of the PIN needle.

[0037] Furthermore, the cover plate 4 is connected to the fixing seat 3 by bolts. The bolt connection facilitates the disassembly and assembly of the cover plate 4 and the fixing seat 3, and facilitates the inspection or replacement of the positioning fixture 2.

[0038] As an example, a support frame 5 is further included, the fixed seat 3 is mounted on the support frame 5, a mounting seat 6 is further provided on the support frame 5, the driving cylinder 11 is mounted on the mounting seat 6, a track plate 61 is further provided on one side of the mounting seat 6, and the rack 12 is slidably connected to the track plate 61. The support frame 5 can support the fixed seat 3 and the driving cylinder 11 and facilitate installation, and by providing the track plate 61 on one side of the mounting seat 6, the driving cylinder 11 can be axially limited, providing support and reducing friction.

[0039] Finally, it should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or terminal device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or terminal device.
