Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
Examples
Referring to fig. 1-2, a novel high-precision six-degree-of-freedom platform, includes the platform body (the specific structure of the platform body is disclosed in the patent with the patent number CN201922417335.4 applied by me), the platform body is composed of an upper platform 10, a lower platform 20 and three groups of electric cylinder driving sets 30, and the three groups of electric cylinder driving sets 30 are connected and arranged between the upper platform 10 and the lower platform 20, a turntable 70 is arranged at the top of the upper platform 10, a plurality of rollers 40 are fixed on the upper platform 10 by arranging a plurality of mounting structures 50, and the turntable 70 is in contact with the plurality of rollers 40, a rotation driving component 60 is arranged at the center of the upper platform 10, and an output end 62 of the rotation driving component 60 is fixedly connected with the turntable 70.
In this embodiment, the rotation driving assembly 60 includes a motor 61 fixed at the center of the bottom surface of the upper platform 10, and a transmission 63 connected to the output end of the motor, and the output end 62 of the transmission passes through the upper platform 1010 and is fixed to the turntable 70. The rotation of the turntable 70 is driven by the rotation driving assembly 30, and the rotation speed is controlled by the transmission 63, so that the multidirectional freedom degree of the platform can be realized, and the rotation speed can be correspondingly controlled.
In this embodiment, the plurality of rollers 40 are disposed on the surface of the upper platform 10 in an annular array, so that the turntable 70 can run smoothly and the service life of the turntable 70 can be prolonged.
In the embodiment, in order to avoid the roller 40 from sliding off when the platform moves in multiple directions, the roller 40 is considered to be provided with a mounting structure, the mounting structure 50 comprises a base 51 and a supporting block 52, a mounting groove 56 is cut on the side surface of the base, the supporting block 52 is placed in the mounting groove 56 and fixed through a bolt 55, studs 53 are arranged on two sides of the top of the base 51, each stud 53 penetrates through the upper platform 10 and is screwed with a nut for fixing, and the roller 40 is connected with the supporting block 52 through a rotating shaft 54, so that the roller 40 is always kept at a fixed position on the upper platform 10 and cannot swing.
The above embodiments are merely illustrative of the technical ideas and features of the present invention, and are intended to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the scope of the present invention. All equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
