Detailed Implementation

[0023] To more clearly illustrate the technical solutions in the embodiments of the invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0024] Refer to the instruction manual. Figure 1 -Appendix Figure 6 This technical solution will be described.

[0025] As shown in the figure, a robot joint quick connection device includes a plug assembly and a socket assembly. The plug assembly includes a plug socket 14, in which a docking claw 3 and a floating electrical connector 5 are disposed. The docking claw 3 and the floating electrical connector 5 are fixedly connected to the plug socket. A plug nut 4 is disposed on the plug socket 14 and is movably connected to the plug socket 14. The socket assembly 2 includes a threaded shaft 9, in which a docking claw seat 11 and a floating electrical connector 10 are disposed. The docking claw seat 11 and the floating electrical connector 10 are fixedly connected to the threaded shaft.

[0026] A guide pin is provided on the plug socket 14, and the guide pin is fixedly connected to the plug socket 14. The guide pin includes a first guide pin 8 and a second guide pin 7. The first guide pin 8 is fixedly connected to the plug socket 14, and the second guide pin 7 is connected to the floating electric connector 5. A guide hole is provided on the threaded shaft 9, and the guide hole corresponds to the guide pin. The guide hole includes a first guide hole 13 and a second guide hole 12. The first guide hole 13 corresponds to the first guide pin 8, and the second guide hole 12 corresponds to the second guide pin 7.

[0027] A locking screw 6 is provided on the plug nut 4. The locking screw 6 is threadedly connected to the plug nut 4. The outer shaft surface 301 of the mating claw head 3 is in contact with the inner hole surface 901 of the threaded shaft 9.

[0028] This utility model tightly connects the 4 nuts and the 9-threaded shaft, and tightens the 6 locking screws to complete the mechanical and electrical connection of the 1 plug assembly and the 2 socket assembly. The cooperation between the 4 nuts and the 9-threaded shaft can withstand a large axial force, while the cooperation between the 3-fork head and the 11-fork seat can withstand a large torsional force, bending moment, and radial force. The 301 outer shaft surface of the 3-fork head and the 901 inner hole surface of the 9-threaded shaft can also resist large bending moments. The 6 locking screws hold the 9-threaded shaft in place to prevent the threaded connection from loosening.

[0029] This application incorporates a first pair of locating pins in the mechanical structure and uses a floating electrical connector. The floating electrical connector is equipped with a second pair of locating pins to prevent misalignment or damage of the electrical connector during mechanical structure docking.
