Electrorheological fluid hydrostatic guideway system

Abstract

The invention discloses an electrorheological fluid hydrostatic guideway system and relates to the technical field of oil supply of a hydraulic supporting element of a precision machining tool. The system comprises a T-shaped guideway, a slide carriage, at least one first controller and at least one second controller, wherein the guideway comprises a supporting part and a guiding part, the periphery of the guiding part is coated with the slide carriage, and the space between the slide carriage and the guiding part is filled with electrorheological fluid; one end of each first controller is fixed to the guideway, the other end of each first controller is fixed to the slide carriage, one end of each second controller is fixed to the guideway, and the other end of each second controller is fixed to the slide carriage; each first controller comprises a first oil chamber, and each second controller comprises a second oil chamber; the thickness of the electrorheological fluid between the slide carriage and the guiding part is kept unchanged by controlling the intensity of the electric field in each first oil chamber and the intensity of the electric field in each second oil chamber. By applying the electrorheological fluid to the hydrostatic guideway, compared with mechanical adjustment, the system has the advantages that the thickness of the electrorheological fluid can be adjusted at the millisecond level, response speed is high and adjustment range is wide.

Description

technical field [0001] The invention relates to the field of machine tool hydrostatic guide rails, in particular to an electrorheological fluid static pressure guide rail system. Background technique [0002] The hydrostatic guide rail is referred to as the hydraulic guide rail for short. It transports the oil with a certain pressure to the oil cavity on the guide rail surface through the restrictor to form a bearing oil film, which separates the metal surfaces that are in contact with each other, and realizes liquid friction. [0003] Since hydrostatic guide rails can work without wear in a wide range of speeds (including static) and loads, they are widely used in ultra-precision machine tools. Regardless of the influence of temperature in actual work, the viscosity of hydraulic oil is basically unchanged. The load-bearing performance corresponding to each oil chamber is also fixed, therefore, each oil chamber must be connected in series with a throttle to adjust the flow ...
