Embodiment Construction

[0020] The technical solutions of the present invention will be clearly and completely described below through specific embodiments.

[0021] A mechanical arm of a robot comprises a connecting rod arm, a grasping device, and a joint device. The connecting rod arm is connected with the grasping device, and the grasping device is internally provided with a joint device.

[0022] Such as figure 1 As shown, the connecting rod arm is composed of a four-link structure, and a four-link structure is hinged on the frame. The four-link structure includes an active rod 1, a first connecting rod 2, a second connecting rod 3, a driven rod 4, Arm board 5. The active rod 1 is connected to the servo motor and driven by the servo motor. The active rod 1 is hingedly connected to one end of the first connecting rod 2, and the other end of the first connecting rod 2 is hingedly connected to the second connecting rod 3. One end is fixed on the frame, the other end of the second connecting rod 3 ...

Abstract

The invention discloses a mechanical arm of a robot. The mechanical arm of the robot is characterized in that a link arm is connected with a grabbing device, and drives the grabbing device to move, ajoint device is arranged inside the grabbing device, the link arm is formed by a four-link structure, the four-link structure is arranged on a machine frame in a hinged mode, and is connected with anarm plate, one end face of the arm plate is supported and fixed through the hinged position between a driving rod and a first link and the hinged position between a second link and a driven rod, the grabbing device is fixed at the other end face of the arm plate, and is provided with a first clamping block and a second clamping block, the lower end face of the first clamping block is provided witha sunken portion, the upper end face of the second clamping block is provided with a sunken portion, and the first clamping block and the second clamping block cooperate with each other to clamp an article. According to the mechanical arm of the robot, the rotational motion, the swinging motion and the loosing and tightening motion of the grabbing device are realized, and the positioning precision is high.

Description
