Embodiment Construction

[0035] Below in conjunction with accompanying drawing, technical content of the present invention is described:

[0036] Such as figure 1 , the turntable is axially supported by the closed static pressure guide rail composed of the main guide rail 1 and the reverse preload guide rail 2. The main guideway 1 is a constant current static pressure guideway, which is composed of a moving guideway and a static guideway. The main guideway on the work surface 4 is a moving guideway, and the main guideway on the base 3 is a static guideway. The reverse preload guide rail 2 is a floating static pressure guide rail combined with constant current and constant pressure. The constant pressure system controls the size of the reverse preload, and the constant current system controls the thickness of the oil film.

[0037] Such as figure 2 , Figure 2A , Figure 2B , the static guide rail of the main rail is a deep and shallow oil cavity structure, the shallow oil cavity 7 is distributed ...

Abstract

The invention relates to a constant-current and constant-voltage composite type floating hydrostatic guide rail, which comprises a main guide rail (1), a reverse preloading guide rail (2), a base (3) and a worktable surface (4), wherein the main guide rail (1) and the reverse preloading guide rail (2) form a closed type hydrostatic guide rail to realize a supporting function, the main guide rail (1) is a constant-current hydrostatic guide rail, and consists of a movable guide rail and a fixed guide rail, the main guide rail (1) on the worktable surface (4) is the movable guide rail, the main guide rail (1) on the base (3) is the fixed guide rail, and the reverse preloading guide rail (2) is the constant-current and constant-voltage composite type floating hydrostatic guide rail. The constant-current and constant-voltage composite type floating hydrostatic guide rail has the advantages that a high-speed and low-speed indexing function of a rotary table is met, and an assembly process and a control method are simple and reliable.

Description

technical field [0001] The invention is applied to an axial support system of a large and heavy numerically controlled rotary workbench, and belongs to the technical field of advanced manufacturing and automation. In particular, it relates to a constant current and constant pressure compound floating static pressure guide rail and a control method thereof. Background technique [0002] In 2013, the major science and technology project of "High-end CNC Machine Tools and Basic Manufacturing Equipment" listed "gear turning and hobbing compound processing machine tools" and "large-scale, high-precision CNC forming gear grinding machines" as research contents, and high and low-speed CNC rotary tables have therefore become An important indexing function part. The turning and grinding of the outer circle, inner hole and end face of the gear requires high-speed rotation of the turntable at a speed of 10~50r / min; the generating hobbing and form grinding of the gear requires continuo...
