[0034] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments:

[0035] A rotating tab connection ring, see Figure 1-Figure 5A rotating connector ring comprises a lens mounting portion 1, a camera mounting portion 2 and a horizontal connecting portion 3 fixed to the camera mounting portion 2, wherein the horizontal connecting portion 3 is used for fixed connection with a tripod, the camera mounting portion 2 comprises a mounting ring 103, the horizontal connecting portion 3 is fixed on the outer wall of the mounting ring 103, and the two are fixedly connected by a pin and a screw, and the camera mounting portion 2 is fixedly connected to the interface of the camera.

[0036] The lens mounting portion 1 is rotatably connected to the mounting ring 103 on the camera mounting portion 2 via the rotating ring 4. Specifically, Figure 2-3 As shown, the lens mounting part 1 is connected to an eccentric plate 101, and the outer edge of the eccentric plate 101 is circular. The lens mounting part 1 is fixed in the deflection hole of the eccentric plate 101, and the eccentric plate 101 is rotatably set on the rotating ring 4. When the rotating ring 4 rotates as a whole, the lens mounting part 1 can rotate around the axis of the rotating ring 4. Due to the deflection hole on the deflection plate 101, the lens mounting part 1 is also eccentric to the rotating ring 4, so that the movement of the lens axis is realized when the rotating ring 4 rotates, achieving the axis shift effect, and when the rotating ring 4 rotates 360°, the lens can also rotate eccentrically 360° around the axis of the rotating ring 4.

[0037] The eccentric plate 101 is provided with a positioning groove 102. Figure 3 As shown, the positioning groove 102 is arranged on the outer edge of the eccentric plate 101 and is in an open state, and the rotating ring 4 is provided with a rotating hole 404 adapted to the outer edge of the eccentric plate 101, so that the eccentric plate 101 can be placed in the rotating hole 404, and the bottom of the rotating hole 404 is provided with a positioning pin 401 that matches the positioning groove 102 of the eccentric plate 101. After the eccentric plate 101 is placed in the rotating hole 404, the positioning groove 102 matches the positioning pin 401. At this time, the eccentric plate 101 cannot rotate relative to the rotating hole 404, thereby realizing the circumferential positioning of the eccentric plate 101.

[0038] To facilitate the removal of the eccentric plate 101, a plurality of clamping plates 402 are rotatably provided on the rotating ring 4. After the clamping plates 402 are rotated, they cooperate with the eccentric plate 101 to axially position the eccentric plate 101 and the rotating ring 4. When the clamping plates 402 are rotated away from the eccentric plate 101, that is, when the eccentric plate 101 is not limited, the eccentric plate 101 is removed; different types of lens mounting parts 1 are equipped with eccentric plates 101, so that different types of lens mounting parts 1 can be installed and replaced through the eccentric plates 101.

[0039] In order to realize the rotation of the rotating ring 4 on the mounting ring 103, thereby achieving the axis shift effect of the lens, an annular rotating groove 104 is opened on the outer wall of the mounting ring 103, and a locking pin 403 that is engaged with the rotating groove 104 is fixedly penetrated on the outer wall of the rotating ring 4. The locking pin 403 is preferably a threaded pin, one end of which is threadedly connected to the wall of the rotating ring 4, and the other end is penetrated through the wall of the rotating ring 4 and placed in the rotating groove 104, and one end placed in the rotating groove 104 is provided with a chamfer, so that the rotating ring 4 is rotatably engaged with the mounting ring 103 through the locking pin 403, and the rotation damping of the rotating ring 4 is controlled by the gap between the end of the locking pin 403 and the rotating groove 104.

[0040] In order to further enhance the axis shift effect between the rotating ring 4 and the mounting ring 103, even if the lens has a positioning effect after the rotating ring 4 is rotated by a fixed angle, the positioning pin 401 is movably arranged on the rotating ring 4, and one end of the positioning pin 401 can be passed through the rotating ring 4 and abutted against the matching end surface of the mounting ring 103, and a plurality of camera position holes 105 matching the rotated positioning pin 401 can be arranged around the circumference on the mounting ring 103. When the rotating ring 4 rotates relative to the mounting ring 103, the rotating ring 4 drives the eccentric plate 101 to rotate a certain angle through the positioning pin 401, and the positioning pin 401 close to one end of the mounting ring 103 falls into a camera position hole 105 for positioning, so that the photographer can sense the angle of the axis shift.

[0041] In this embodiment, a number of snap-in pins 403 are evenly arranged around the circumference of the rotating ring 4, and 8 are shown in this embodiment, so that the rotation of the rotating ring 4 is more stable. During installation, each snap-in pin 403 needs to be inserted into the mounting hole of the rotating ring 4 from the outside of the rotating ring 4, and the snap-in pin 403 is screwed after cooperating with the snap-in pin 403 through the thread in the mounting hole, so that the snap-in pin 403 is placed in the rotating ring 4 and one end gradually penetrates into the rotating slot 104 to cooperate with it. If the snap-in pin 403 thread is rotated excessively, the rotating ring 4 and the mounting ring 103 will be stuck. If the snap-in pin 403 and the rotating slot 104 are not properly engaged, the rotating ring 4 and the mounting ring 103 will be too loosely engaged, resulting in a gap, which is not conducive to damping rotation. Therefore, this embodiment also provides a production device for a rotating joint connecting ring.

[0042] like Figure 6-Figure 11 As shown, a production device for a rotating joint ring includes a main frame 5, on which a clamping unit for clamping a mounting ring 103 and an assembly unit for mounting a rotating ring 4 are provided;

[0043] The clamping unit includes a second mounting frame 507 and a clamping cylinder 508. The second mounting frame 507 is provided with a first clamping block 509. The first clamping block 509 is provided with a positioning rod and an arc surface which are the same as the horizontal connecting part 3, that is, the mounting ring 103 can be adapted to the first clamping block 509 through the above-mentioned positioning rod and arc surface, so that the shape of the first clamping block 509 fits with the mounting ring 103, and the mounting ring 103 is circumferentially positioned by the positioning rod.

[0044] The clamping cylinder 508 is provided with a second clamping block 510, the second clamping block 510 has the same shape as the first clamping block 509, and is arranged at 180 degrees with the first clamping block 509. The cylinder body of the clamping cylinder 508 is fixed on the second mounting frame 507, and the push rod end is fixedly connected to the second clamping block 510. The clamping cylinder 508 is preferably a guide rod cylinder. When the mounting ring 103 is matched with the first clamping block 509 through the hole body matched with the horizontal mounting part 3, the clamping cylinder 508 is then actuated to make the second clamping block 510 clamp and match with the outer wall of the mounting ring 103, so that the mounting ring 103 is fixed on the clamping unit. Figure 6-7 shown.

[0045] The assembly unit includes an assembly plate 501, which is used to position the rotating ring 4 and install the rotating ring 4 on the mounting ring 103. Specifically, the main frame 5 is provided with a connecting rod 504 rotatably connected to the assembly plate 501 and a pushing cylinder 505 connected to the connecting rod 504, and the main frame 5 is provided with a first mounting frame 506 for installing the pushing cylinder 505.

[0046] The assembly plate 501 is provided with a positioning rod 502 that cooperates with the rotating ring 4, and the end face of the rotating ring 4 on the side away from the mounting ring 103 is provided with a first hole body 5001 that is compatible with the positioning rod 502. Preferably, two first hole bodies 5001 are provided. When in use, the positioning rod 502 is inserted into the first hole body 5001 of the rotating ring 4 to fix the rotating ring 4 on the assembly plate 501.

[0047] The circumference of the assembly plate 501 is provided with a driving unit 6 that is compatible with the number of the snap-in pins 403 and is used to install the snap-in pins 403 in the rotating ring 4. In this embodiment, there are 8 snap-in pins 403 of the connecting ring, and 8 groups of driving units 6 are arranged on the assembly plate 501. The driving unit 6 can drive the snap-in pins 403 to rotate and push them to move and position into the rotating slot 104.

[0048] The driving unit 6 includes a driving rod 601, a guide rod 602 and a driving gear 603 that slides with the guide rod 602. The snap-in pin 403 is a threaded pin with a hexagonal hole on it. The snap-in pin 403 can be rotated in the rotating ring 4 through the hexagonal hole and screwed into the rotating slot 104. Therefore, the end of the driving rod 601 is a hexagonal rod that matches the hexagonal hole on the snap-in pin 403.

[0049] The driving rod 601 is connected to the guide rod 602 through a threaded rod 604, and a threaded plate 605 matching with the threaded rod 604 is provided on the assembly plate 501, and the threaded rod 604 is threadedly matched with the threaded hole in the threaded plate 605, and a reset push rod 503 connected to the threaded plate 605 and driving it to slide is provided on the assembly plate 501, and the push rod seat of the reset push rod 503 is fixed on the assembly plate 501, and the push rod end is fixed to the threaded plate 605. Initially, the driving rod 601 is located away from the rotating ring 4. At this time, the reset push rod 503 is in the pushed-out state, and then the hexagonal hole of the snap-in pin 403 is placed on the end of the driving rod 601, and then the reset push rod 503 is actuated, so that the threaded plate 605 drives the threaded rod 604 to slide toward the rotating ring 4, so that the snap-in pin 403 at the end of the driving rod 601 enters the mounting hole of the rotating ring 4.

[0050] The driving gear 603 is rotatably clamped on the bracket of the assembly plate 501, and the guide rod 602 is slidably penetrated by the driving gear 603. The guide rod 602 is preferably a hexagonal rod. The driving gear 603 is provided with a hexagonal hole adapted to the guide rod 602. A gear ring 606 meshing with the driving gear 603 is rotatably provided on the assembly plate 501, and the gear ring 606 is provided with a first tooth portion 607. A driving motor 608 is provided on the assembly plate 501, and the driving motor 608 is provided with a gear ring meshing with the first tooth portion 607 to make the gear ring 606 The driving gear 609 rotates, and the driving motor 608 is preferably a servo motor. The gear ring 606 is provided with a second tooth portion 610 meshing with the driving gear 603, that is, when the driving motor 608 drives the gear ring 606 to rotate, the gear ring 606 can rotate the driving gear 603 meshing therewith, and at this time, the guide rod 602 rotates synchronously, and due to the cooperation between the threaded rod 604 and the threaded plate 605, the guide rod 602 slides toward the rotating ring 4 at the same time, and at this time, the engaging pin 403 is screwed into the rotating slot 104 through a thread, so that the engaging pin 403 is assembled.

[0051] A clutch 8 is provided between the threaded rod 604 and the guide rod 602. The clutch 8 can be disengaged after the guide rod 602 rotates forward to reach a torque, so that the threaded rod 604 is disengaged from the guide rod 602. At this time, the engaging pin 403 is in a state of being pressed against the rotating slot 104. At this time, it is difficult for the rotating ring 4 to rotate relative to the mounting ring 103. In order to achieve appropriate rotation damping between the rotating ring 4 and the mounting ring 103, a damping push rod 701 for setting the rotation damping is provided in this embodiment. The connecting rod 504 is provided with a vertical plate fixed thereto, the damping push rod 701 is provided on the vertical plate, a push plate 702 is fixedly provided at the push rod end of the damping push rod 701, a detection pin 703 connected to the push plate 702 is fixedly provided on the end surface of the assembly plate 501 close to the pushing cylinder 505, and a long groove 704 matching with the detection pin 703 is provided on the push plate 702, that is, the detection pin 703 is provided with the long groove 704; the damping push rod 701 can set the thrust.

[0052] When the clutch 8 is disengaged, the assembly plate 501 is connected to the rotating ring 4 through the driving rod 601. At this time, the rotation of the assembly plate 501 can drive the rotating ring 4 to rotate synchronously. Therefore, after the damping push rod 701 sets the thrust, the driving motor 608 is slowly reversed, so that the gear ring 606 is reversed to drive the guide rod 602 and the driving rod 601 to rotate counterclockwise synchronously. At this time, the clutch 8 is re-engaged. At the beginning, it is difficult for the damping push rod 701 to push the assembly plate 501 to rotate through the detection pin 703. When the driving rod 601 rotates counterclockwise, the clamping pin is gradually loosened. 403, the end of the engaging pin 403 in the rotating ring 4 gradually disengages from the rotating slot 104 by a certain gap. At this time, when the gap is sufficient to allow the rotating ring 4 to rotate relative to the mounting ring 103, the thrust set by the damping push rod 701 is just reached. The damping push rod 701 moves to push the assembly plate 501 to rotate relative to the mounting ring 103. Then the PLC controller quickly controls the drive motor 608 to stop rotating, completing the assembly of the engaging pin 403. Then the drive rod 601 disengages from the hexagonal hole of the engaging pin 403 during the process of pushing out the reset push rod 503, completing the assembly.

[0053] In this embodiment, the reset push rod 503, the ejection cylinder 505, the damping push rod 701, the clamping cylinder 508 and the drive motor 608 are all connected to the PLC controller, so that the automated production of the production device can be realized and the efficiency is improved; in addition, the end of the drive rod 601 preferably has magnetic force, and the locking pin 403 has ferromagnetism; the clutch 8 can be a magnetic clutch, or a conventional elastic tooth clutch. In addition, the prior art will not be described in detail here.

[0054] A method for using a production device for a rotating joint ring as described above: the method is as follows:

[0055] S1: Place the mounting ring 103 on the first clamping block 509, then drive the clamping cylinder 508 to slide the second clamping block 510 to clamp and fix the mounting ring 103; at the same time, place the rotating ring 4 on the positioning rod 502 for positioning, and place the clamping pins 403 one by one on the end of the driving rod 601 through the hexagonal holes;

[0056] S2: Drive the push-out cylinder 505 to slide the assembly plate 501 to the mounting ring 103. At this time, the rotating ring 4 and the mounting ring 103 are sleeved together, and the threaded hole on the rotating ring 4 that cooperates with the engaging pin 403 corresponds to the rotating slot 104.

[0057] S3: Start the reset push rod 503 and retract it. At this time, the driving rod 601 slides to drive the clamping pin 403 to slide into the threaded hole of the rotating ring 4, and then the driving motor 608 is started;

[0058] S4: After the driving motor 608 rotates, the driving gear 603 on the driving unit 6 rotates clockwise through the gear ring 606. At this time, the driving rod 601 rotates to screw the clamping pin 403 into the threaded hole of the rotating ring 4. At the same time, the driving rod 601 slides synchronously with the cooperation of the threaded rod 604 and the threaded plate 605, so that it is always in a matching state with the hexagonal hole of the clamping pin 403.

[0059] S5: After the engaging pin 403 is pressed against the rotating slot 104, the clutch 8 is disengaged, and then the driving motor 608 slowly reverses, and at the same time, the damping push rod 701 is powered on to push the detection pin 703. After the driving motor 608 reverses, the driving rod 601 reverses to loosen the engaging pin 403, so that a certain gap is generated between the end of the engaging pin 403 and the occupying slot 104. When the damping push rod 701 can push the detection pin 703 according to the set thrust, the surface engaging pin 403 has been installed in place, and the driving motor 608 is powered off at this time;

[0060] S6: After the driving motor 608 is powered off, the driving rod 601 is pushed out of the rotating ring 4 through the reset push rod 503, and then the cylinder 505 is pushed out to drive the assembly plate 501 to slide to the side away from the rotating ring 4. At this time, the rotating ring 4 has been rotated and clamped on the mounting ring 103 through the clamping pin 403, and has a certain rotational damping with the mounting ring 103.

[0061] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
