Problems solved by technology
This requires a larger space, making the cross-sectional area of the forearm perpendicular to its rotation axis larger, thereby increasing the moment of inertia of the robot and reducing the overall response performance and positioning accuracy of the robot

Embodiment Construction
[0017] The robot arm component and the robot using the robot arm component will be further clarified below in conjunction with the drawings and specific embodiments.
[0018] see figure 1 , The robot 100 of one embodiment includes a base 10 , a boom 30 and a robot arm member 50 .
[0019] see figure 2 , the boom 30 drives the boom 30 to rotate relative to the base 10 through the driving member 12 and the transmission mechanism 14 arranged between the boom 30 and the base 10 . The robot arm part 50 drives the robot arm part 50 to rotate relative to the big arm 30 through the driving part 32 and the transmission mechanism arranged between the big arm 30 and the robot arm part 50 .
[0020] A limiting member 16 is disposed on the base 10 . The limiting member 16 and the boom 30 are located at the same end of the base 10 and the limiting member 16 is spaced apart from the boom 30 . There are two limiting members 16 in total, and the two limiting members 16 are spaced apart to...

The invention discloses an arm component for robots, and the arm component comprises a small arm, an output shaft, a driver, a transmission mechanism, a pushing part and a driving part, wherein the output shaft is arranged on the small arm, the driver drives the output shaft to rotate around the axis line of the output shaft and relative to the small arm, the transmission mechanism is arranged between the driver and the output shaft, and the driving part drives the pushing part to move; the output shaft relative to the transmission mechanism can slide relative to the small arm along the axis line of the output shaft; the driving part drives the pushing part to slide along the axis line of the output shaft; the pushing part is rotatably connected with the output shaft; and an axis line (rotating relative to the output shaft) of the pushing part and the axis line of the output shaft are collinear. The rotary inertia of the arm component for robots disclosed by the invention is small, and the overall responsiveness and positioning accuracy of a robot are high. The invention also provides a robot adopting the arm component for robots.
Description
【Technical field】 [0001] The invention relates to a robot arm part and a robot using the robot arm part. 【Background technique】 [0002] The SCARA (Selective Compliance Assembly Robot Arm) robot has greater flexibility in the horizontal direction and strong rigidity in the vertical direction. This selective flexibility is widely used in high-efficiency assembly, dispensing, and welding and handling areas. The SCARA robot is mainly composed of a base, a large arm, a small arm, a motor, a reducer, an actuator, etc. It has four joints, and the axes of the three rotating joints are parallel to each other to achieve positioning and orientation in the plane. In addition, the small arm is attached with a Sliding joints for vertical movement of end pieces. The vertical motion and rotational motion of the rotary joint and the sliding joint on the small arm of the SCARA robot are realized by the combination of the spline shaft and the screw rod, and the arrangement on the small arm ...
