Abstract
The invention pertains to a regulation method of a static pressure guideway straightness, pertaining to mechanical manufacturing field; the static pressure guideway comprises a moving guideway and a fixed guideway, and the moving guideway and the fixed guideway are separated by a static pressure oil slick. The invention is characterized in that: the straightness errors of each point of the moving guideway in the height direction are measured by using the lowest point of the moving guideway as a benchmark point when the moving guideway moves on the fixed guideway; an assistant guideway is arranged on the fixed guideway, and has the same moving direction as and moves synchronously with the moving guideway, an electromagnetic coil is arranged on the assistant guideway, and an electromagnetic iron core is arranged on the moving guideway in the corresponding position. According to the measured height error value of each point in the moving guideway relative to the benchmark point, the needed forces for each point to be pressed to the benchmark point are measured, and the current values and the voltage values that the electromagnetic iron core needs to generate the forces thereof are calculated; an electromagnetic coil of the assistant guideway is electrified with the corresponding current values and voltage values of each point, and the electromagnetic forces that each point of the electromagnetic iron core sustains ensure that each point of the moving guideway move in a flat straight line of the benchmark point from beginning to end. The invention has the scientific, reasonable and high straightness regulation precision.
Description
Technical field
The invention belongs to field of mechanical manufacture technology, specifically is a kind of regulating method of static pressure extensible guide straight-line degree.
Background technique
In the machining, the error control technique of straightness accuracy is a basic technology, and hydrostatic slideway is the constituent element of accurate and ultra-precision machine tool, because the error in the manufacture process is inevitable, so how this part error is compensated, thereby the straightness accuracy of control hydrostatic slideway motion seems and is even more important.I install an overflow device at the patent " a kind of hydrostatic slideway that adopts multi-head constant displacement pump " (number of patent application is 200610052426.7) of application between each static pressure oil pocket and its static pressure oil pump, adjust slide block and decide guide clearance by the section area of regulating the overflow device oil outlet, thereby the straightness accuracy that keeps slide block movement, though this method is effective within the specific limits, but in reality was made, the guide rail linearity error was regulated the comparison difficulty that seems in time below 0.3 micron.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, provide that a kind of degree of regulation is higher, the regulating method of more reliable static pressure extensible guide straight-line degree.
Technological scheme of the present invention is as follows:
A kind of regulating method of static pressure extensible guide straight-line degree, this hydrostatic slideway comprises moving guide rail, decides guide rail, moving guide rail and decide to isolate by the static pressure oil film between guide rail, it is characterized in that: when moving guide rail is being decided to move on the guide rail, minimum point is a reference point during with moving guide rail movement, and each point is at the straightness error of short transverse when measuring moving guide rail movement; Deciding to adorn secondary guide rail on the guide rail, the moving direction of secondary guide rail is identical with moving guide rail, and is synchronized with the movement with moving guide rail, adorns electromagnetic coil on the secondary guide rail, on moving guide rail relevant position electromagnetic core is housed; With respect to the height error value of reference point, required power when measuring each point and being depressed into reference point calculates electromagnetic core and produces the needed current/voltage value of this suction according to each point on the moving guide rail of measuring; Pass to the current/voltage value of each point correspondence on the electromagnetic coil of secondary guide rail, the suffered electromagnetic force of electromagnetic core each point is moved each point on the guide rail all the time on the straight straight line of reference point.
The present invention is by deciding that the secondary guide rail that has electromagnetic coil is installed on the guide rail, on the corresponding moving guide rail electromagnetic core is installed, electromagnetic core generation suction makes the guide rail each point stressed behind the logical upward current/voltage, and remain at and decide and move on the straight straight line of guide rail reference point, thereby the moving guide rail of control and decide straightness error between the guide rail.The present invention regulates straightness accuracy precision height, and is scientific and reasonable.
Description of drawings
Fig. 1 is a schematic representation of the present invention.
Embodiment
As shown in Figure 1, a kind of regulating method of static pressure extensible guide straight-line degree, this hydrostatic slideway comprises moving guide rail 1, decides guide rail 2, moving guide rail 1 with decide 2 on guide rail by 3 isolation of static pressure oil film, concrete steps are: when moving guide rail 1 is being decided to move on the guide rail 2, minimum point is a reference point during with moving guide rail 1 motion, and each point is at the straightness error of short transverse when measuring moving guide rail 1 motion; Deciding to adorn secondary guide rail 4 on the guide rail 2, the moving direction of secondary guide rail 4 is identical with moving guide rail 1, and is synchronized with the movement with moving guide rail 1, and dress electromagnetic coil 5 is equipped with electromagnetic core 6 on the secondary guide rail 4 on moving guide rail 1 relevant position; With respect to the height error value of reference point, required power when measuring each point and being depressed into reference point calculates electromagnetic core 6 and produces the needed current/voltage value of these suction according to each point on the moving guide rail of measuring 1; Pass to the current/voltage value of each point correspondence on the electromagnetic coil 5 of secondary guide rail 4, the suffered electromagnetic force of electromagnetic core 6 each points is moved each point on the guide rail 1 all the time on the straight straight line of reference point.
The present invention can arrange in the horizontal direction in like manner that also one group of secondary guide rail and corresponding electromagnetic coil, electromagnetic core are with control straightness error in the horizontal direction.
Moving guide rail 1 of the present invention and decide 2 on guide rail and also can isolate by the static pressure air film.
