Detailed Embodiments

[0019] Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Embodiment: Please refer to Figures 1-3, a structure of a screw - tightening manipulator, including a bottom plate 1 and a robotic arm 2. The robotic arm 2 is installed at the upper end of the bottom plate 1. One end of the robotic arm 2 is provided with a tool - bit installation driving structure, and tool - bit storage structures are arranged on both sides of the upper end of the bottom plate 1;

[0021] The tool - bit installation driving structure includes: a fixing plate 3, an electric push rod 4, four guide rods 5, a moving mounting plate 6, a mounting frame 7 and a driving assembly;

[0022] The fixing plate 3 is fixedly installed at one end of the robotic arm 2. The electric push rod 4 is installed on one side wall surface of the fixing plate 3. The four guide rods 5 are all installed on one side of the fixing plate 3. The moving mounting plate 6 is movably sleeved on the upper ends of the four guide rods 5. The telescopic end of the electric push rod 4 is connected to one side of the moving mounting plate 6. The mounting frame 7 is installed on one side of the moving mounting plate 6, and the driving assembly is installed on one side of the mounting frame 7.

[0023] During use, first place this device at a designated position, and use the bottom plate 1 to support the whole device. Subsequently, connect the robotic arm 2 to a designated driving device, and let the robotic arm 2 operate according to a designated program. Take the bits stored in the tool - bit storage structure, and automatically install them through the driving assembly. Finally, move the driving assembly to a position through the robotic arm 2 and contact a designated screw to tighten the screw. During the tightening process, the electric push rod 4 on one side of the fixing plate 3 works to push the moving mounting plate 6 to move to one side on the upper ends of the four guide rods 5, changing the positions of the mounting frame 7 and the driving assembly, so as to ensure that the bit always remains in contact with the tip of the screw.

[0024] In the specific implementation process, the driving assembly includes: a bearing seat 8, a bearing frame 9, a mounting sleeve 10, a strong magnet block 11, a motor 12, a first gear 13 and a second gear 14;

[0025] The bearing seat 8 is installed at the center of one side of the mounting frame 7. Both ends of the bearing frame 9 are respectively connected to both sides of the side wall surface of the mounting frame 7. The mounting sleeve 10 is movably embedded in the bearing seat 8 and the bearing frame 9. The strong magnet block 11 is fixedly embedded on one side wall surface inside the mounting sleeve 10. The motor 12 is installed on one side of the upper end of the bearing frame 9. The first gear 13 is installed on the driving end of the motor 12. The second gear 14 is sleeved on the upper end of the mounting sleeve 10 and meshes with the first gear 13.

[0026] When installing the bit and turning the screw, the strong magnetic block 11 on one side inside the installation sleeve 10 contacts one end of the bit to adsorb and fix the bit, and the operation hole 16 inside the installation sleeve 10 is sleeved on one end of the bit to stably install the bit. During the turning operation, the motor 12 on one side of the bearing bracket 9 works, and drives the installation sleeve 10 to rotate inside the bearing seat 8 and the bearing bracket 9 under the cooperation of the first gear 13 and the second gear 14. The bit inside the installation sleeve 10 contacts the screw to perform the turning operation on the screw.

[0027] In the specific implementation process, a limit block 15 is provided at the lower end of the guide rod 5.

[0028] In the specific implementation process, an operation hole 16 is formed on one side of the installation sleeve 10.

[0029] In the specific implementation process, the tool bit storage structure includes: two support rods 17, two storage trays 18, and a storage cavity 19;

[0030] The two support rods 17 are respectively installed on both sides of the upper end of the bottom plate 1, the two storage trays 18 are respectively installed on the upper ends of the two support rods 17, and the storage cavity 19 is formed on the upper end of the storage tray 18.

[0031] When replacing the tool bit, the mechanical arm 2 works to move the installation sleeve 10 to the upper end of the designated storage cavity 19, and embed the bit inside the installation sleeve 10 into the storage cavity 19 on the upper end of the storage tray 18. Then, the mechanical arm 2 moves slightly to one side, so that the bit is in close contact with the inner wall on one side of the storage cavity 19. The storage tray 18 is made of rubber material, and the friction between the bit and one side of the storage cavity 19 is greater than the adsorption force between the bit and the strong magnetic block 11. By moving the mechanical arm 2 upward, the disassembly of the bit can be realized. Then, the mechanical arm 2 moves the installation sleeve 10 to the upper end of the designated bit, and the strong magnetic block 11 inside the installation sleeve 10 contacts the top end of the bit, so as to realize the replacement and installation operation of the bit.

[0032] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
