Embodiment Construction

[0011] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0012] refer to figure 1 As shown, a novel workbench driven by a friction pull rod includes a light workbench 1, a granite guide rail 2 and a drive mechanism 3, and the light workbench 1 is floatingly arranged above the granite guide rail 2. The drive mechanism 3 includes an L-shaped base plate 31, a C-shaped pre-loaded plate 32 is installed on the vertical plate of the L-shaped base plate 31, and an air cushion 33 and a motor friction wheel are sequentially installed below the C-shaped pre-loaded plate 32. 34. A traction rod 35 is arranged between the air cushion 33 and the motor friction wheel 34, and the traction rod 35 is connected with the lightweight workbench 1.

[0013] Further, the inner surface of the lightweight workbench 1 is in sliding contact with the side surface of the granite guide rail 2, the opening of the C-shape...

Abstract

The invention discloses a novel workbench driven by a friction pull rod. The novel workbench comprises a light workbench body, granite guide rails and driving mechanisms, the light workbench body is arranged above the granite guide rails in a floating manner, each driving mechanism comprises an L-shaped baseplate, a C-shaped preloading plate is mounted on a vertical plate of each L-shaped baseplate, an air cushion and a motor friction wheel are sequentially mounted below each C-shaped preloading plate, and a traction rod is arranged between each air cushion and the corresponding motor friction wheel and connected with the light workbench body. The novel workbench driven by the friction pull rod is good in rigidity, long in working stroke, high in positioning accuracy and less prone to thermal deformation.

Description

technical field [0001] The invention relates to the field of cutting-edge industrial production and scientific research, in particular to a novel workbench driven by a friction pull rod. Background technique [0002] The ultra-precision table system is divided into two categories according to the accuracy and stroke size: small stroke, extremely high-precision table system and large stroke, high-precision table system. Most of the extremely high-precision worktables with small strokes use piezoelectric elements or electromagnetic elements as driving devices. Most strokes are in the range of tens of microns, but the displacement resolution can be as high as 1nm. The large-travel high-precision workbench refers to the workbench system with a stroke of more than millimeters, but the positioning accuracy is slightly lower than that of the small-stroke system. Most of them use linear motor or friction drive mode, and the motion resolution is mostly around 10nm, but the drive mo...
