Problems solved by technology

[0003] Robotic arms often use linear arms to articulate with each other to achieve multi-degree-of-freedom movements, and install knives, claws, etc. on the end of the arm to perform a specific action. Movement, but because the pivoted arms are linear, so when it is necessary to bypass obstacles for operation, at least three arms need to be pivoted to avoid obstacles before operating the object to be operated. The structure is relatively Complicated; when the operating object is not a plane, it is necessary to continuously adjust the distance between the tool, gripper, etc. installed on the arm and the operating object for operation, which is inconvenient to operate

Embodiment Construction

[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0017] Please also see figure 1 and figure 2 , the robotic arm 100 includes a pivot mechanism 10 , a first arm 20 , a second arm 30 , a pivot mechanism 50 and an actuating mechanism 70 . Wherein the first arm 20 and the second arm 30 are pivotally connected by the pivot mechanism 50, the actuating mechanism 70 is arranged at the end of the second arm 30, and the actuating mechanism 70 is driven by the first arm 20 and the second arm 30 to An operation object (not shown) can perform a specific action.

[0018] Please also see image 3 and Figure 4 , the shaft connection mechanism 10 includes a rotating shaft 11 , a fixing part 13 and a driving part 15 . The rotating shaft 11 is a stepped shaft and has a first axis A. The rotating shaft 11 includes a first shaft segment 111 and a second shaft segment 113. In this embodiment, the ...

Abstract

The invention discloses a mechanical arm comprising a first arm, a second arm, a spindle and an execution piece, wherein the first arm and the second arm are mutually pivoted; the spindle is arranged on one end, far away from the second arm, of the first arm; the execution piece is arranged on one end, far away from the first arm, of the second arm; the spindle is provided with a first axis; the second arm can rotate relatively to the first arm; a rotation axis serves as a second axis; at least one of the first arm and the second arm is in curved structure; the first arm can rotate around the first axis; and an included angle between the first axis and the second axis is more than 0 degree and less than 180 degrees. The mechanical arm has simple structure and is convenient to operate.

Description

technical field [0001] The invention relates to a robot, in particular to a mechanical arm of a robot. Background technique [0002] Because some production needs to be carried out in harsh environments such as high-risk and high pollution, which may cause harm to the personal safety or health of operators, robots are often used to replace operators in such production environments. The mechanical arm is a necessary part for the robot to realize various operation actions. [0003] Robotic arms often use linear arms to articulate with each other to achieve multi-degree-of-freedom movements, and install knives, claws, etc. on the end of the arm to perform a specific action. Movement, but because the pivoted arms are linear, so when it is necessary to bypass obstacles for operation, at least three arms need to be pivoted to avoid obstacles before operating the object to be operated. The structure is relatively Complicated; when the operating object is not a plane, it is necess...
