Magnetic suspension driving type guide mechanism

Abstract

The invention relates to the technical field of precision machinery, and discloses a magnetic suspension drive type guide mechanism, which comprises two bases, a guide rail, a first suspension device and a second suspension device, wherein the two bases are arranged in parallel at an interval, a magnetic coil and a permanent magnet are arranged on the left base, a permanent magnet is arranged on the right base, the guide rail is erected on the two bases in a suspension mode, the first suspension device is arranged on the left side of the guide rail, a first magnetic suspension assembly is arranged on the left side of the first suspension device, a second magnetic suspension assembly is arranged at the bottom of the first suspension device, the second suspension device is arranged on the right side of the guide rail, and a third magnetic suspension assembly is arranged at the bottom of the second suspension device. According to the invention, the motion friction of the guide mechanism can be effectively reduced while the gravity influence of the guide rail and all assemblies of the guide rail is counteracted, high-precision magnetic driving of the guide rail is achieved, the problems that in an existing precise motion guide mechanism, the mass of the guide rail is too large, the motion control difficulty is high, and the assembly error is large are solved, and the motion precision of the guide mechanism is further improved.

Description

technical field [0001] The invention relates to the technical field of precision machinery, in particular to a magnetic levitation driven guiding mechanism. Background technique [0002] With the continuous development of mechanical and electronic technology, the demand for mechatronic structure is more diverse. The traditional coarse-motion mechanical structure is difficult to meet the high-precision transmission requirements, and has gradually been replaced by more complex and precise mechanisms. In order to realize the complex movement of the motion module in the horizontal plane, the combination of the slider and the motion guide rail can be used to control the X-direction and Y-direction movement separately, and synthesize it into a horizontal plane movement. However, the processing accuracy of traditional mechanical guide rails and guide rail brackets is difficult to guarantee, which will cause shape and position errors during installation and are difficult to adjust, ...
