A second driving device 5 is provided, and the second driving device 5 is connected to the second rotating disk 4. The second driving device 5 drives the second rotating disk 2 to work. A tightening device 6 is provided on the top of the operating platform 1 between the first rotating disk 2 and the second rotating disk 4. The setting of the tightening device 6 realizes the function of assembling and assembling between the screw and the nut. Combined with the above-mentioned structural design, the first rotating disk and the second rotating disk respectively carry the nut and the screw. When the first rotating disk 2 and the second rotating disk 4 rotate and drive, the nut and the screw overlap, and then the nut is rotated and screwed onto the screw through the tightening device 6. The design of this structure effectively replaces the traditional manual assembly method, improves production efficiency, and reduces production costs.

[0032] In this embodiment, the first rotating disk 2 includes a first rotating disk 21, a first driving shaft 22 and a nut fixture 23. The first driving shaft 22 is fixedly connected to the bottom of the first rotating disk 21, and the connection between the first rotating disk 21 and the first driving device 3 is realized through the setting of the first driving shaft 22. The nut fixture 23 is evenly distributed and fixedly installed on the top of the first rotating disk 21. A nut mounting position 231 is opened on the nut fixture 23, which is set for the purpose of loading the nut. The first driving shaft 22 is fixedly connected to the output end of the first driving device 3, and the first rotating disk 21 is driven to rotate through the connection of the first driving shaft 22 by the output end of the first driving device 3.

[0033] In this embodiment, the second rotating disk 4 includes a second rotating disk 41 and a second driving shaft 42. The second driving shaft 42 is fixedly connected to the bottom of the second rotating disk 41, and screw mounting positions 43 are evenly distributed on the top of the second rotating disk 41. The load-bearing effect on the screw is achieved through the screw mounting positions 43, and the second driving shaft 42 is fixedly connected to the output end of the second driving device 5.

[0034] In this embodiment, the tightening device 6 includes a lower positioning mechanism 61, an upper tightening mechanism 62, a support frame 63 and a connecting frame 64. The support frame 63 is fixedly installed on the top surface of the operating platform 1, and the upper tightening mechanism 62 is fixedly installed on the side of one side of the support frame 63.

This structural design can fix the screw rod and assist the upper tightening mechanism 62 to smoothly screw the nut into the screw rod. A connecting frame 64 is fixedly installed on one side of the support frame 63 between the upper tightening mechanism 62 and the lower positioning mechanism 61. The function of the connecting frame 64 is to achieve that the first turntable 21 and the second turntable 41 will have an overlap point during the rotation process, and the overlap point is located at the connecting frame 64, which plays a role in auxiliary positioning for subsequent maintenance.

[0035] In this embodiment, the lower positioning mechanism 61 includes a first cylinder 611 and a screw positioning column 612. The first cylinder 611 is fixedly installed on the bottom surface of the operating platform 1, and the output end of the first cylinder 611 is fixedly connected to the screw positioning column 612, so that the screw positioning column 612 has the function of extending up and down, and the screw positioning column 612 passes through the operating platform 1 and moves under the connecting frame 64.

[0036] In this embodiment, the upper tightening mechanism 62 includes a sliding component 621, a second cylinder 622, a mounting plate 623, a servo motor 624 and a tightener 625. The sliding component 621 is fixedly connected to one side of the support frame 63, and the second cylinder 622 is fixedly installed on the top of the support frame 63, and the output end of the second cylinder 622 is fixedly connected to the top of the sliding component 621. The second cylinder 622 is provided to provide a power source for the sliding component 621 to slide up and down. The sliding component 621 is fixedly connected to the mounting plate 623 at one end away from the support frame 63, and the servo motor 624 and the tightener 625 are fixedly installed on the top of the mounting plate 623. The servo motor 624 is connected to the tightener 625 through a connecting belt 65, so that the tightening and rotating function of the tightener 625 is driven by the servo motor 624. A tightening head 626 is fixedly connected to the bottom of the tightener 625, and the tightening head 626 passes through the mounting plate 623 and moves above the connecting frame 64.

[0037] In this embodiment, a movable opening 641 is provided on the surface of the connection frame 64 at a position opposite to the tightening head 626 to avoid the tightening head 626 , and the tightening head 626 and the screw positioning column 612 are movably connected in the movable opening 641 .

[0038] How it works

[0039] During specific use, the first turntable 21 and the second turntable 41 rotate synchronously, and the overlapping point of the first turntable 21 and the second turntable 41 is located directly below the connecting frame. At the same time, the first cylinder 611 and the second cylinder 622 perform upward and downward output work respectively, respectively driving the screw positioning column 612 and the mounting plate 623 to move upward and downward, the screw positioning column 612 positions the screw on the second turntable 41, and the tightening head 626 clamps the nut on the first turntable 21, and the servo motor 624 drives the tightener 625 to rotate, and the tightening head 626 is driven by the tightener 625 to rotate, so that the nut is smoothly assembled with the screw under the influence of the rotation.

It cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, they can also make several simple deductions or substitutions, which should be regarded as belonging to the scope of protection determined by the claims submitted for the utility model.
