Mechanical hand arm telescopic and rotary compound motion mechanism

Abstract

The utility model relates to a mechanical hand arm telescopic and rotary composite motion mechanism, including telescopic arm main part and rotating seat, the inside of telescopic arm main part is provided with the extension mechanism that extends to the inside rotating seat, be provided with two groups with the extension mechanism connected auxiliary guide component on telescopic arm main part. The mechanical hand arm telescopic and rotary composite motion mechanism, through setting extension mechanism and auxiliary guide component, first two output ends of bidirectional slow -running motor will drive two screw rods stable rotation synchronously, then through setting the thread connection relation between auxiliary extension sleeve rod and screw rod, make two screw rods stable rotation while two auxiliary extension sleeve rod also will produce corresponding linkage, finally through setting limit slide, L type guide rod and guide fixed plate, make two auxiliary extension sleeve rod can carry out stable telescopic activity in telescopic arm main part, and further realize the purpose that the mechanical hand arm is stable and telescopic, its practicality is stronger.
