Embodiment Construction

[0009] Such as figure 1 As shown, a parallel mechanism consists of an upper platform, a moving platform and three branch chains. The first and second branch chains are identical, consisting of three rotating pairs with parallel axes. The first and second branch chains are arranged on both sides of the upper platform and symmetrical to the center of the upper platform; the third branch chain is connected by The platform and the parallelogram mechanism of the moving platform are composed of a parallelogram mechanism. The branch chain does not contain a driving pair. The branch chain is a driven branch chain. The moving pairs in the mechanism are all rotating pairs. 2 is a rotating platform, which can be used for two-degree-of-freedom translation. The first and second branch chains are composed of four rods. Rod a3 and rod b4 are connected to the upper platform 1 through a rotating pair; rod c5 and rod d6 are connected to the lower platform 2 through a rotating pair, and the upp...

Abstract

A parallel mechanism comprises an upper platform, a moving platform and three branched chains. The three branched chains are parallelly mounted between the upper platform and the moving platform, the first branched chain and the second branched chain are arranged on two sides of a frame, are symmetric about the center of the frame and comprise four rods a, b, c and d, the rods a and b are connected with the upper platform through a rotating pair, and the rods c and d are connected with the moving platform through a rotating pair. The parallel mechanism is characterized in that the upper platform and the rods are connected by rotating hinges, the rods are connected by rotating hinges, and the rods and the moving platform are connected by rotating hinges. The parallel mechanism structurally has fine symmetry, the inertia of a driving motor less affects dynamical properties in the moving process of the mechanism, the connecting rods are light in weight, the moving platform can bear high acceleration, and high-speed carrying operation is facilitated. The transfer process of the parallel mechanism is performed completely by the aid of the rods from movement input to movement output, overall rigidity and precision of the parallel mechanism are improved, and output of effective power is increased.

Description

technical field [0001] The invention belongs to the field of high-speed transport operations, in particular to a three-degree-of-freedom translational parallel mechanism for high-speed transport operations. Background technique [0002] In the existing technology, the research of a new type of robot mechanism that can meet the requirements of high-speed operation is one of the frontier topics in the research of robot mechanisms in the world. It requires high rigidity, therefore, the parallel mechanism has gradually received special attention from experts and scholars, and has been applied in specific situations. However, due to the small operating range of the parallel mechanism, it has not been widely used in industrial robots. Contents of the invention [0003] In view of the above deficiencies, the purpose of the present invention is to provide a parallel mechanism with simple and reliable structure, low manufacturing and maintenance costs, easy control, and suitable f...
