Abstract
The utility model relates to a four-degree-of-freedom paralleling working platform which comprises a moveable platform (1), a slide block mechanism and a guide rail mechanism, wherein the slide block mechanism comprises four slide blocks (5-1, 5-2, 5-3 and 5-4) arranged on a cross guide rail (6), the lower ends of four connecting rods (3-1, 3-2, 3-3 and 3-4) with fixed length are respectively connected with the four slide blocks (5-1, 5-2, 5-3 and 5-4), and the upper ends thereof are respectively and correspondingly connected with the moveable platform (1) by spherical hinges (2-1, 2-2, 2-3 and 2-4). By installing workpieces on the moveable platform, the working platform realizes multidirectional processing of the workpieces, and is convenient to be combined with various machine tools for use due to the simple structure thereof. The few-degree-of-freedom paralleling working platform avoids the defects of high manufacturing cost and control difficulty, unreasonable dimension ratio of a working space to the configuration of the machine tool, low precision, and the like of a six-degree-of-freedom paralleling mechanism.
Description
Technical field
The utility model relates to the technical field of lower-mobility parallel machine workbench.
Background technology
Parallel institution the earliest is used for the detection of tire.It can be used for flight simulator, and the pilot is carried out simulated training.Parallel institution is widely used in the development of parallel robot subsequently.The beginning parallel institution was used to design research and development Parallel CNC Machine Tool in 1994.Six degree of freedom and Three Degree Of Freedom is more in the current parallel machine kind.But the parallel machine of six degree of freedom exists manufacturing cost and control technology height, working space and appearance and size than shortcoming such as unreasonable, that precision is low, has reduced in recent years with its structure as parallel machine.And the lower-mobility parallel institution has nothing motion coupling, big, the advantages of simple structure and simple of working space, becomes the development main flow of parallel machine in the world.Wherein, 3-freedom parallel mechanism is constructed easily, so there are a lot of people that it is researched and developed.Four, the parallel institution of five degree of freedom is few, but their application in industry are but more extensive.
Summary of the invention
The purpose of this utility model is to provide a kind of four-degree-of-freedom parallel operation platform at defective of the prior art, thereby has effectively overcome a series of problems of the described existence of background technology.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of four-degree-of-freedom parallel operation platform, include moving platform 1, slide block and guide rail mechanism, described slide block mechanism comprises and is arranged on the first slide block 5-1 on the cross guide rail 6, the second slide block 5-2, the 3rd slide block 5-3, Four-slider 5-4, the first fixed length connecting rod 3-1, the second fixed length connecting rod 3-2, the 3rd fixed length connecting rod 3-3, the lower end of the 4th fixed length connecting rod 3-4 respectively with the first slide block 5-1, the second slide block 5-2, the 3rd slide block 5-3, Four-slider 5-4 links to each other, the first fixed length connecting rod 3-1, the second fixed length connecting rod 3-2, the 3rd fixed length connecting rod 3-3, the upper end of the 4th fixed length connecting rod 3-4 is corresponding to respectively the ball first hinge 2-1, the second hinge 2-2, the 3rd hinge 2-3, the 4th hinge 2-4 links to each other with moving platform 1.
The utility model is compared with background technology, described four-degree-of-freedom parallel operation platform, thereby its workbench realize workpiece is carried out multi-faceted processing by workpiece being installed on the moving platform, it is simple in structure simultaneously, is convenient to be used in combination with multiple class lathe.This lower-mobility parallel operation platform has avoided the six-degree-of-freedom parallel connection mechanism manufacturing cost and the control difficulty is big, working space and machine overall dimension be than shortcomings such as unreasonable and precision are low.
