Problems solved by technology

[0002] A manipulator is an automatic operating device that can imitate certain movements and functions of the human hand and arm to grab, carry objects or operate tools according to a fixed program. At present, industrial robots and service robots require different end effectors, and the manipulator claw is one of them. In order to meet the needs of different applications, different end effectors have been designed, including the claw type; at present, the claw type end effector is often only a simple double-joint structure, which is not available for finer and more complex products. Good clamping effect, and the control motion precision is ...

Abstract

The invention provides a full-hydraulic humanoid manipulator which comprises a control module and a gripper module. The full-hydraulic humanoid manipulator is characterized in that the control module comprises a control motor, a threaded shaft, a bearing, a valve, a valve body and a pipe joint; the control motor is connected with the threaded shaft; a bearing is arranged between the threaded shaft and the valve; the valve is fixedly arranged at the other end of the threaded shaft and is arranged in the valve body; the pipe joint is arranged under the valve body; through a precise liquid flow control device, a finger knuckle liquid flow can be controlled, so that the requirement on adjusting each finger according to the needs can be met; and fingers are driven through a precise special micro oil cylinder and are automatically controlled through a computer, so that opening, closing and grasping of any finger at different degrees can be realized. The strength magnitude can be adjusted through a control pressure valve according to the feedback.

Example Embodiment

[0034] Example 1:
[0035] The manipulator is set as figure 2 The two-finger structure shown. The control motor 1 is controlled by the program instructions and can perform macro single-step or continuous rotation, and drive the threaded shaft 2 to rotate. The threaded shaft 2 and the valve 4 are connected by precision fine thread, because the threaded shaft 2 and the bearing 3 that cannot move up and down Fixed connection, therefore, when the threaded shaft 2 rotates, it drives the valve 4 to move up and down, thereby controlling the opening and closing degree of the valve 4 to achieve the purpose of controlling the flow rate of the liquid flow; at the same time, a clamp channel 5012 is set in the flow channel. The width of the flow channel is preferably set to 1mm. The liquid flow comes to the oil pipe through the connection port-the conduit-the first oil connection port. When the liquid flow enters the first oil port 803 and exits the second oil port 804, the piston 801 is pushed to move downward , Produce mechanical finger grasping action; on the contrary, when the liquid flow comes out from the first oil port 803 and the second oil port 804 enters, it will produce the action of spreading the fingers, and the change of the oil port liquid flow direction can be electrically controlled by the reversing valve.

Example Embodiment

[0036] Example 2:
[0037] The manipulator has a three-finger structure. It can be set to have two fingers on one side and one finger on the other side, or it can be set with three fingers distributed in a triangle. The control motor 1 is controlled by program instructions, and it can perform macro single step or continuous rotation, and drive the threaded shaft 2 to rotate. 2 The axis and the valve 4 are connected with precision fine threads. Because the threaded shaft 2 is fixedly connected to the bearing 3 that cannot move up and down, when the threaded shaft 2 rotates, it drives the valve 4 to move up and down, thereby controlling the opening and closing of the valve 4. To achieve the purpose of controlling the size of the liquid flow; at the same time, a clamp flow channel 5012 is set in the flow channel. The width of the flow channel is preferably set to 0.8mm. The liquid flow comes to the tubing through the nozzle-pipe-first oil-receiving port, When the liquid flow enters from the first oil port 803 and the second oil port 804 exits, the piston 801 is pushed to move downward, causing the gripping action of the mechanical fingers; on the contrary, the liquid flow comes out of the first oil port 803 and the second oil port 804 When it enters, it produces the action of spreading the finger, and the change of the flow direction of the oil port can be electrically controlled by the reversing valve.
