[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] See also Figures 1 to 7 The utility model provides a rotatable pressing pin assembly, including a rotary mounting positioning plate 1, a rotary cylinder 3 is installed on the rotary mounting positioning plate 1, and the rotary cylinder 3 is fixedly installed on the rotary mounting positioning plate 1 by fasteners, which can be bolts and other commonly used parts for installation. A rotary disk 4 is installed on the rotating end of the rotary cylinder 3 by bolts, and the rotary disk 4 can be driven to rotate by the rotating end of the rotary cylinder 3. The rotary disk 4 is installed at one end of the rotary disk 4 away from the rotary cylinder 3 and has several groups of embedded nail head positioning ends 5 distributed in a mirror image with each other. The embedded nail head positioning ends 5 can be specifically provided with two groups. Of course, multiple groups of embedded nail head positioning ends 5 can also be provided according to actual processing requirements. There are multiple nail head mounting ends 6. Similarly, two groups of nail head mounting ends 6 can be set, or multiple groups can be set according to actual production needs. Moreover, the size setting of the nail head mounting end 6 can be replaced according to different pins. It should be noted that there needs to be a clearance fit between the inner hole of the nail head mounting end 6 and the outer diameter of the pin, that is, the inner hole of the nail head mounting end 6 is larger than the outer diameter of the pin. One side of the rotary disk 4 is provided with multiple pneumatic joints 7 matching several groups of nail head positioning ends 5. The interior of the rotary disk 4 is provided with several vacuum air paths corresponding to the nail head mounting ends 6 and the pneumatic joints 7. The vacuum air path is specifically matched between each group of nail head mounting ends 6 and the pneumatic joints 7. Through the vacuum air path, negative pressure can be introduced through the pneumatic joints 7 to achieve pin suction;

[0024] When this device is in use, negative pressure is introduced through the pneumatic joint 7, and then the suction process of the pin at a processing position can be completed through the pin head mounting end 6 on the pin head positioning end 5. When the pin head mounting end 6 on one group of pin head positioning ends 5 has completed the suction of the pin, by starting the rotary cylinder 3, the rotary disk 4 can be driven to rotate by the rotating end of the rotary cylinder 3. Since several groups of pin head positioning ends 5 are mirror-image distributed and the rotary disk 4 can rotate, when the rotary disk 4 rotates, the different groups of pin head positioning ends 5 on the rotary disk 4 can exchange positions. That is, when the pin head mounting end 6 on one group of pin head positioning ends 5 has completed the suction, the rotary disk 4 can rotate to make the pin head positioning end 5 on the rotary disk 4 that has not sucked the pin rotate to the processing position to complete the suction of the pin. Through this method, multiple suctions of pins can be achieved at the same processing position.

[0025] Please refer to Figures 1 to 3 , an auxiliary ring 12 for assisting rotation is also provided between the rotary disk 4 and the rotating end of the rotary cylinder 3. The auxiliary ring 12 is located between the rotary disk 4 and the rotary cylinder 3 and is used to make the contact part between the rotary disk 4 and the rotary cylinder 3 fit better, make the rotary disk 4 rotate more smoothly, and play an auxiliary role.

[0026] Please refer to Figures 1 to 7, further comprising an overpressure protection structure, which includes a spring compression plate 2, a spring, a linear bearing 8, a guide post 11 and a trigger assembly. The spring compression plate 2 is arranged on the side of the rotary mounting and positioning plate 1 away from the rotary cylinder 3. A plurality of springs are arranged between the spring compression plate 2 and the rotary mounting and positioning plate 1. A plurality of linear bearings 8 are fixed at both ends of the rotary mounting and positioning plate 1. The guide post 11 is movably arranged on the linear bearing 8, and one end of the guide post 11 passes through the rotary mounting and positioning plate 1 and is fixed to the spring compression plate 2. When the spring compression plate 2 is subjected to a downward pressure, first, the spring will press the rotary mounting and positioning plate 1 downward with a force in the same direction. When the downward pressure exceeds the elastic force of the spring at this time, the spring will continue to compress. At this time, the distance between the rotary mounting and positioning plate 1 and the spring compression plate 2 will become closer. The trigger assembly is arranged between the rotary mounting and positioning plate 1 and the spring compression plate 2. The trigger assembly includes a machine screw 9 and a metal inductor 10. The machine screw 9 is arranged on one side of the rotary mounting and positioning plate 1, and the metal inductor 10 is correspondingly arranged on the side of the spring compression plate 2 close to the machine screw 9. After the machine screw 9 moves, it can be close to the detection end of the metal inductor 10. When the rotary mounting and positioning plate 1 moves, the machine screw 9 will be close to the detection end of the metal inductor 10. When the metal inductor 10 detects the machine screw 9 through its detection end, at this time, the pressure applied to the spring compression plate 2 is cancelled, and the working process of the overpressure protection structure can be realized, avoiding the spring compression plate 2 from being subjected to excessive pressure, so as to prevent the nail-embedded head positioning end 5 in this device from exerting a large pressure on the pin, and ensuring the force during the downward pressing process.

[0027] Please refer to Figures 1 to 7 , at the end of the nail-embedded head positioning end 5 away from the rotary disk 4, a rivet 13 is further arranged. The arrangement of the rivet 13 can be used to cooperate with an external riveting opening to play a positioning role.

[0028] The working principle of this device is as follows: First, determine the number of the nail-embedded head positioning end 5 and the nail-embedded head mounting end 6 required for the to-be-processed position, and then complete the assembly. During processing, through the pneumatic joint 7, in cooperation with the vacuum circuit and the nail-embedded head mounting end 6, the pin is sucked. Then, by starting the rotary cylinder 3, the rotary disk 4 is driven to rotate, realizing multiple suction operations on the same to-be-processed position, increasing the number of pins that can be sucked at the same batch of to-be-processed positions, and thus improving the processing efficiency;

[0029] In addition, through the spring compression plate 2, spring, linear bearing 8, guide post 11 and trigger assembly provided in this device, during use, when the spring compression plate 2 is subjected to a downward pressure, the spring will press the rotary mounting positioning plate 1 downward with a force in the same direction. When the force of the downward pressure exceeds the elastic force of the spring at this time, the spring will continue to compress. Then, through the cooperation of the machine screw 9 and the metal inductor 10, it is ensured that the downward pressure is within a controllable range, avoiding the inconvenience brought to the pin by excessive pressure, ensuring that the processing link is controllable, and improving the processing accuracy.

[0030] Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
