Multi-degree-of-freedom metamorphism parallel-connection stacking mechanical arm

Abstract

Provided is a multi-degree-of-freedom metamorphism parallel-connection stacking mechanical arm. The lower end of a first telescopic rod of the mechanical arm is connected to a working platform; the upper end of the first telescopic rod is connected with one end of a first rod; the other end of the first rod is connected to an actuator; the lower end of a second rod is connected to a sliding block; the sliding block is installed in a sliding groove in the working platform; the upper end of the second rod is connected to a first sliding sleeve; the first telescopic rod is sleeved with the first sliding sleeve; the lower end of a second telescopic rod is connected to the working platform; the upper end of the second telescopic rod is connected to a second sliding sleeve; the first rod is sleeved with the second sliding sleeve; the lower end of a third rod is connected to the working platform; the upper end of the third rod is connected to the first corner of a triangular connection board; one end of a third telescopic rod is connected to the actuator; the other end of the third telescopic rod is connected to the second corner of the triangular connection board; the third corner of the triangular connection board is connected with the first telescopic rod and the first rod. The multi-degree-of-freedom metamorphism parallel-connection stacking mechanical arm has the advantages of large working space, large digging force and good stress of a traditional hydraulic press mechanism, reduces the number of driving rods and controllable motors, and reduces complexity of a rack transmission system.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a multi-degree-of-freedom metamorphic parallel palletizing manipulator. Background technique [0002] Excavator is a kind of common construction machinery, which is mainly used in various engineering operations. Among them, the hydraulic excavator is a type of excavator widely used at present, but the hydraulic excavator has problems such as high manufacturing cost of the hydraulic system and prone to oil leakage. However, traditional single-degree-of-freedom mechanical excavators, commonly known as "electric shovels", can only achieve simple and unchangeable trajectory output, so they cannot be used in a wide range of fields like hydraulic excavators. [0003] With the development of motor technology and the improvement of control technology, the controllable mechanism provides a broad development space for construction machinery. The multi-degree-of-freedom controllable mechanism driv...
