Controllable mechanism type transfer robot arm

Abstract

The invention discloses a controllable mechanism type transfer robot arm. The lower end of a first telescopic rod of the robot 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 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 a sliding block. The sliding block is installed in a sliding groove in 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 a first corner of a triangular connecting plate. One end of a third telescopic rod is connected to the actuator. The other end of the third telescopic rod is connected to a second corner of the triangular connecting plate. A third corner of the triangular connecting plate is connected with the first telescopic rod and the first rod at the same time. The controllable mechanism type transfer robot arm has the advantages of a traditional hydraulic mechanism that the working space is large, the digging force is large and the stress is good; meanwhile, the number of driving rods and the number of controllable motors are reduced, and the complexity of a machine frame transmission system is lowered.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a controllable mechanism-type handling robot. 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 driven by the control motor no...
