Problems solved by technology
[0002] Most of the high-precision vertical worktables in the prior art are supported by plane thrust bearings and radial roller bearings. Their rotation accuracy is restricted by rolling bearings, and it is difficult to make a breakthrough improvement. Most of the accuracy is in the order of percent It is several millimeters in size, and its vibration absorption performance is very poor, so it can no longer adapt to the processing of modern high-precision parts, especially for large-scale high-precision parts in aviation, aerospace, wind power and other industries, let alone meet its precision requirements

Embodiment Construction
[0029] The specific implementation of the present invention will be described in further detail below by describing the embodiments with reference to the accompanying drawings, so as to help those skilled in the art have a more complete, accurate and in-depth understanding of the inventive concepts and technical solutions of the present invention.
[0030] like figure 1 The structure of the present invention expressed is a high-precision constant-current closed-type full-static vertical workbench. It includes a base 5, a worktable 1 installed on the base 5, a driving wheel 4 and a driven wheel 3 that are externally engaged with each other, and the driven wheel 3 is arranged under the workbench 1, and the driven wheel 3 is connected to the The workbench 1 is coaxially fixedly connected.
[0031] The lower surface of workbench 1 is tightly connected with high-strength screw 2 and driven wheel 3, and the driving wheel 4 that meshes with each other drives it to rotate to complete...

The invention discloses a high-precision vertical type working table which comprises a base, a working table mounted on the base, as well as a driving wheel and a driven wheel which are externally meshed with each other, wherein the driven wheel is arranged below the working table and coaxially and fixedly connected with the working table; an upward bulged round boss is arranged on the base, and the driven wheel is nested on the round boss through a round hole to form the clearance fit; and a circumferential static-pressure oil cavity is formed between matched surfaces of the round boss and the driven wheel. With the adoption of the technical scheme, a closed static-pressure support with high rigidity and high anti-inclining moment is formed on the working table under the actions of upper, lower and radial static-pressure supporting force; and the driven wheel is supported by a high-pressure oil film to move in the axial direction and the radial direction, so that the working table has the advantages of high rotation accuracy, high rigidity, high anti-inclining moment, simple structure and small starting moment.
Description
technical field [0001] The invention belongs to the technical field of mechanical manufacturing equipment, and relates to a workbench structure of a large-scale machining machine tool. More specifically, the invention relates to a high-precision vertical workbench. Background technique [0002] Most of the high-precision vertical worktables in the prior art are supported by plane thrust bearings and radial roller bearings. Their rotation accuracy is restricted by rolling bearings, and it is difficult to make a breakthrough improvement. Most of the accuracy is in the order of percent It is several millimeters in size, and its vibration absorption performance is very poor, so it can no longer adapt to the processing of modern high-precision parts, especially for large-scale high-precision parts in aviation, aerospace, wind power and other industries, let alone meet its precision requirements. Contents of the invention [0003] The invention provides a high-precision vertical...
