The direction is installed on the top of the main frame body, the u-shaped frame is rotatably connected to the main frame body, the second motor is used to drive the u-shaped frame to rotate relative to the main frame body, the The first motor is used to drive the main frame body to rotate relative to the support.

6. In the aforementioned robot head motion mechanism, preferably, the first bearing mechanism includes a transition ring, a first bearing and a first connecting flange, and the transition ring is fixed on the top of the support, so The first bearing is arranged on the top of the transition ring, the outer ring of the first bearing is fixedly connected with the transition ring, the first connecting flange is fixedly connected with the inner ring of the first bearing, so A first motor connection shaft is formed on the first connection flange, and the first motor output shaft is connected with the first motor connection shaft by plugging.

7. In the aforementioned motion mechanism of the robot head, preferably, a rotation limit pin is formed on the top of the outer ring of the first bearing, and a limit groove is formed on the first connecting flange, and the limit groove is formed on the top of the outer ring of the first bearing. In cooperation with the rotation limiting pin, the rotation angle of the first connecting flange is limited.

8. In the aforementioned robot head motion mechanism, preferably, the main frame body includes a first side plate, a second side plate, a bottom plate and a connecting plate, and one end of the bottom plate is fixed to the lower end of the first side plate. The other end is fixedly connected to the lower end of the second side plate, the number of the connection plates is at least two, and the connection plates are arranged between the first side plate and the second side plate, so One end of the connecting plate is fixed on the first side plate, the other end is fixed on the second side plate, and the bottom plate is fixed on the first connecting flange.

9. In the aforementioned robot head motion mechanism, preferably, the second motor is fixed between the first side plate and the second side plate, and the second motor bushing on the second motor Passing through the first side plate, a second bearing is fixedly installed on the outer wall of the first side plate, the second bearing is sleeved on the output shaft of the second motor, and on the second connecting flange

A second motor connection shaft is formed, the second motor output shaft is connected with the second motor connection shaft by plug connection, and the second connection flange is fixedly connected with one side of the U-shaped frame.

10. In the aforementioned robot head motion mechanism, preferably, a damper is fixedly installed on the outer wall of the second side plate, and a third connecting flange is fixedly installed on the inner wall of the other side of the u-shaped frame. A flange connection shaft is formed on the third connection flange, and the flange connection shaft is connected with the damper inner hole on the damper by plugging.

11. Compared with the prior art, the present invention includes a first motor, a support, a main frame body, a second motor and a u-shaped frame, the first motor is fixedly installed at the bottom of the support, and the lower end of the main frame body passes through the first motor. A bearing mechanism is rotatably connected with the top of the support, the output shaft of the first motor is connected to the first bearing mechanism after passing through the support, the second motor is installed on the top of the main frame along the horizontal direction, and the u-shaped frame and the main frame can be connected to each other. Rotationally connected, the second motor is used to drive the u-shaped frame to rotate relative to the main frame body, and the first motor is used to drive the main frame body to rotate relative to the support. Through the arrangement of the first bearing mechanism, the utility model enables the main frame body to rotate relative to the support under the driving of the first motor to realize the rotation function of the robot head; and through the arrangement of the second motor and the u-shaped frame, in the first Driven by the second motor, the U-shaped frame can be rotated relative to the main frame body, so as to realize the pitching function of the robot head, and effectively improve the working range of the robot head.
