Abstract
The invention discloses a one-dimensional rotary gas pressure column. The one-dimensional rotary gas pressure column comprises a roller, a piston, one or more supports, and a column body, wherein the upper end of each support is connected with a revolving shaft of the roller, and the lower end of each support is connected with the piston; a first cavity with an upward opening is formedby the upper part of the column body, and a second cavity with a downward opening is formed by the lower part of the column body; the diameter of the cross section of the second cavity is greater than that of the cross section of the first cavity, the second cavity and the first cavity are mutually communicated, and the piston moves in the second cavity; and the lower part of the column body is connected with an external air pressure adjusting device. According to the one-dimensional rotary gas pressure column, the external air pressure adjusting device pressurizes the piston to move with the supports and the roller upwards and provides pressure outwards through the second cavity at the lower part of the column body; rolling friction forms between the roller and a work-piece on the roller, and friction force between the roller and the work-piece is small, so that damage is reduced when the work-piece displacesin a roller rotating direction; and the roller material is elastic, so that the damage caused by the friction is further reduced when the roller is in contact with the work-piece, and precise set pressure can be provided as well.
