[0030] Example:

[0031] See also Figure 1 , Figure 2 and Figure 3 A mechanical electromechanical controlled rotating arm manipulator comprises a first base 1, an inner cavity 3 is provided at the top of the first base 1, a first motor 4 is installed inside the inner cavity 3, an output end of the first motor 4 is fixedly connected to a second base 5, a fixing seat 6 is fixedly connected to the top of the second base 5, a first rotating column 7 is rotatably connected to the outer wall of the fixing seat 6, a second motor 8 is arranged on the right side of the fixing seat 6, an output end of the second motor 8 is fixedly connected to the outer wall of the first rotating column 7, a first connecting arm 9 is fixedly connected to the outer wall of the first rotating column 7, a second rotating column 10 is rotatably connected to the top of the outer wall of the first connecting arm 9, and a rotating assembly is arranged at the top of the first connecting arm 9; the rotating assembly comprises a second connecting arm 1 2. The second connecting arm 12 is fixedly connected to the outer wall of the second rotating column 10. A third motor 11 is arranged on the right side of the first connecting arm 9. The output end of the third motor 11 is fixedly connected to the outer wall of the second rotating column 10. The left and right sides of the front end of the top wall of the second connecting arm 12 are fixedly connected to mounting blocks 13. A hydraulic push rod 14 is installed on the adjacent side of the two mounting blocks 13. The output end of the hydraulic push rod 14 is fixedly connected to a fixed column 15. The outer wall of the fixed column 15 is fixedly connected to a third connecting arm 16. The bottom of the third connecting arm 16 is provided with a clamping mechanism 2. The outer wall end of the second connecting arm 12 is rotatably connected to a third rotating column 17. The outer wall of the third rotating column 17 is fixedly connected to the third connecting arm 16.

[0032] By starting the first motor 4, the working direction of the entire manipulator can be controlled, ensuring that the device can work without dead angles at 360°. By the second motor 8 and the third motor 11, the angles of the first connecting arm 9 and the second connecting arm 12 can be adjusted respectively. When it is necessary to adjust the working angles of the third connecting arm 16 and the clamping mechanism 2, the hydraulic push rod 14 is started to control the movement of the fixed column 15 and the third connecting arm 16, so that the third connecting arm 16 is rotationally connected to the outer wall of the second connecting arm 12 through the third rotating column 17. The flexibility of the device is improved by multiple motors and the hydraulic push rod 14, and it can work at multiple angles and in multiple directions.

[0033] Please refer to Figure 5 , the clamping mechanism 2 includes a mounting plate 201. The mounting plate 201 is fixedly connected to the end of the third connecting arm 16. A plurality of equipment slots 202 are equidistantly opened on the bottom wall of the mounting plate 201. An electric push rod 203 is fixedly connected to the inner wall of the equipment slot 202. The output end of the electric push rod 203 is fixedly connected to a clamping plate 204;

[0034] In this solution, by opening a plurality of equipment slots 202 on the bottom wall of the mounting plate 201, starting the electric push rod 203 drives the clamping plate 204 to move in the equipment slot 202. The clamping plate 204 can stably clamp the workpiece through the pressure of the electric push rod 203, and can also clamp workpieces of different sizes, improving the practicability of the device.

[0035] Please refer to Figure 4 and Figure 5 , an anti-slip layer 20 is fixedly connected to the outer wall of the clamping plate 204; a clamping plate 18 is fixedly connected to the bottom wall of the second base 5, and a clamping groove 19 is opened on the top wall of the first base 1. The clamping plate 18 and the clamping groove 19 are engaged;

[0036] In this solution, by fixedly connecting the anti-slip layer 20 to the outer wall of the clamping plate 204, the friction between the clamping plate 204 and the workpiece can be increased through the anti-slip layer 20, thus ensuring the stability during clamping; the clamping plate 18 is fixedly connected to the bottom wall of the second base 5, and the clamping plate 18 is engaged with the clamping groove 19 on the top wall of the first base 1, so that the second base 5 is slidably connected to the top wall of the first base 1, and thus a part of the gravity of the robotic arm can be shared, reducing the support pressure on the first motor 4 and ensuring the normal operation of the device.

[0037] Working principle: When work needs to be carried out by the manipulator, starting the first motor 4 in the inner cavity 3 can control the working angle of the whole device. Starting the second motor 8 can drive the first rotating column 7 and the first connecting arm 9 to rotate, so as to adjust the angle of the first connecting arm 9. The second connecting arm 12 is rotatably connected to the top end of the first connecting arm 9 through the second rotating column 10. When the angle of the second connecting arm 12 needs to be adjusted, start the third motor 11. At the same time, the third connecting arm 16 is rotatably connected to the end of the second connecting arm 12 through the third rotating column 17. Starting the hydraulic push rod 14 can drive the third connecting arm 16 to move. Since the third connecting arm 16 is simultaneously rotatably connected to the outer wall of the third rotating column 17, when the hydraulic push rod 14 controls the third connecting arm 16 to move, the front end of the third connecting arm 16 will remain stationary and the rear end will rotate, so as to achieve the effect of adjusting the angle of the third connecting arm 16. And when the workpiece needs to be clamped, starting the electric push rod 203 can drive the clamping plate 204 to clamp the outer wall of the workpiece. The clamping plate 204 can ensure stable clamping of the workpiece by receiving the power from the electric push rod 203. At the same time, through the equipment slot 202, the clamping mechanism 2 can clamp workpieces of different sizes and specifications.

[0038] The above is only a preferred specific embodiment of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
