Robotic arm

摘要

In order to reduce the cost of robotic arm, the invention provides a robotic arm, which includes an arm member having a first pivot connection portion, a locating member affixed to the arm member, a sliding member movably mounted at the locating member, a stop member affixed to the sliding member, a wrist member having a second pivot connection portion pivoted to the sliding member and a third pivot connection portion movable relative to the second pivot connection portion, and a driving device including a body member pivoted to the first pivot connection portion and an extension member pivoted to the third pivot connection portion of the wrist member and movable relative to the body member. Using the locating member, the sliding member, the stop member and the wrist member to match with the driving device, the robotic arm achieves the effect of moving and swinging and cost reduction.

主权项

1. A robotic arm, comprising:
an arm member comprising a first pivot connection portion; a locating member fixedly connected to one end of said arm member; a sliding member movably mounted at said locating member; a stop member fixedly connected to said sliding member and adapted to limit the travel range of said sliding member relative to said sliding member and adapted to limit the travel range of said sliding member relative to said locating member; a wrist member comprising a second pivot connection portion and a third pivot connection portion, said second pivot connection portion being pivotally connected to said sliding member; a driving device comprising a body member and an extension member movable relative to each other by an external force, said body member being pivotally connected to said first pivot connection portion, said extension member being pivotally connected to said third pivot connection portion; and an adjustment screw mounted in said stop member and rotatable to change the relative position between said adjustment screw and said stop member.
