A multi-degree-of-freedom industrial machine manipulator arm mechanism

Abstract

The invention discloses a multi-freedom-degree industrial machine operation arm mechanism. The lower end of a first rod of the mechanism is connected to a work platform. The upper end of the first rod is connected to a first sliding sleeve. A second rod is sleeved with the first sliding sleeve. One end of the second rod is connected to an actuator. The other end of the second rod is connected with the upper end of a first telescopic rod. The lower end of the first telescopic rod is connected to a sliding block. The sliding block is installed in a sliding groove in the work platform. The lower end of a second telescopic rod is connected to the work 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. One end of a spring is fixed to the work platform, and the other end of the spring is fixed to the first corner of a triangular connecting plate. One end of a third telescopic rod is connected to the second corner of the triangular connecting plate, and the other end of the third telescopic rod is connected to the actuator. The third corner of the triangular connecting plate is also connected with the first telescopic rod and the second rod at the same time. The multi-freedom-degree industrial machine operation arm mechanism has the beneficial effects of being large in working space and excavating force, good in stress and the like, meanwhile, the number of drive rods and controllable motors is reduced, and complexity of a rack transmission system is lowered.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a multi-degree-of-freedom industrial machine operating arm mechanism. Background technique [0002] The traditional series robot has the advantages of simple structure, low cost, and large working space. Relatively speaking, the series robot has low rigidity and cannot be applied to high-speed and large-load occasions; compared with the traditional series robot, the parallel robot has no cumulative error, High precision, compact structure, large bearing capacity, high rigidity and small inertia of the end effector, etc., the driving device can be placed on the fixed platform or close to the fixed platform, so that the moving part is light in weight, high in speed and good in dynamic response. It has the advantages of large working space, high rigidity, strong bearing capacity, small inertia and high precision of the end effector. It can be used in complex operations such as welding, sprayi...
