Abstract

A parallel mechanism with composite sliding telescopic rods. It includes a fixed platform, a moving platform, a first branch chain, a second branch chain, a third branch chain and a fourth branch chain, and has three translational and two rotational degrees of freedom. The invention has the advantages: on the one hand, the use of compound sliding telescopic rod branches reduces the number of branch chains of the mechanism and reduces interference, thereby increasing the flexibility of the mechanism and expanding the working space of the mechanism, so that the mechanism can complete the expansion and contraction relative to a single mechanism. The movement of the rod mechanism is more complex; on the other hand, the use of three sliding telescopic rod branches with the same structure can increase the transmission efficiency of the mechanism in the vertical direction, and the structure is simple, the assembly is simple, and the difficulty of manufacturing and processing is reduced. The present invention is suitable for processing environments that require multiple degrees of freedom and high flexibility, such as parts processing and assembly.

Description

technical field [0001] The invention belongs to the technical field of parallel mechanisms, and in particular relates to a parallel mechanism comprising a composite sliding telescopic rod. Background technique [0002] The parallel mechanism has been widely used in modern manufacturing. Compared with the series mechanism, the parallel mechanism has the advantages of high rigidity, stable structure, large bearing capacity and high precision. Machining complex parts requires high flexibility of the mechanism, requiring at least five degrees of freedom of movement. [0003] If the configuration of the composite sliding telescopic rod is applied to the parallel mechanism, the space can be effectively utilized, and the utility model has the advantages of strong stability and long service life. Chinese patent CN201610460193.8 discloses a new type of sliding wheel with a telescopic connecting rod. The user can adjust the telescopic connecting rod to change the distance between the...
