The hydraulic oil passage is provided with a proportion flow adjusting valve and a proportion pressure adjusting valve. The control system is respectively connected with the proportion flow adjusting valve and the proportion pressure adjusting valve through a data line. The invention can ensure a worktable to run stably to reach the goal of ultraprecision machining.
Description
Technical field
The present invention relates to a kind of ring-shaped guide rail of super precise vertical type lathe, especially a kind of ring-shaped guide rail of vertical lathe.
Background technology
The ring-shaped guide rail of traditional vertical lathe, all adopt Liquid Static-Press Technique, the hydraulic oil that utilization is arranged on the ring-shaped guide rail face floats workbench, general size according to lathe, the ring-shaped guide rail working face is divided into 6-14 static pressure oil pocket, each oil pocket is adopted constant temperature oil sources fuel feeding, but because the restriction of machining accuracy and structure, just can not guarantee the consistent size of each oil pocket, the oil temperature supplying unanimity of each oil pocket, thus the uniformity of floatation volume between workbench and the ring-shaped guide rail destroyed, swing up and down when making workbench work, especially to super precise vertical type lathe, had a strong impact on its machining accuracy.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of ring-shaped guide rail of vertical lathe, and this guide rail guarantees the Lathe bench motion steadily, reaches the purpose of ultraprecise processing.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of ring-shaped guide rail of vertical lathe, and it comprises a circle static pressure oil pocket and a hydraulic circuit of the annular array that is located on the ring-shaped guide rail, described hydraulic circuit is connected with the static pressure oil pocket; Be provided with temperature sensor and displacement transducer in the described static pressure oil pocket; Described temperature sensor is connected with a control system by data wire respectively with displacement transducer; Described hydraulic circuit is provided with proportional flow adjustable valve and proportional pressure valve; Described control system is connected respectively with proportional pressure valve with the proportional flow adjustable valve by data wire.
Described displacement transducer is a noncontact induction type micron order displacement transducer.
Described temperature sensor is a noncontact thermocouple type micron order temperature sensor.
Operation principle of the present invention is as follows: the hydraulic oil that utilization of the present invention is arranged on the ring-shaped guide rail face floats workbench, because the structural limitations of existing lathe, the resistance of hydraulic oil that leads to each oil pocket is different, causes the oil temperature in each oil pocket different, gap size generation drift.For overcoming the above problems, temperature sensor and displacement transducer are set in each oil pocket, on the fuel feeding road to each oil pocket proportional flow adjustable valve and proportional pressure valve are set, when each oil pocket from temperature sensor and detected oil pocket temperature signal of displacement transducer and size drift signal, feed back to proportional flow adjustable valve and proportional pressure valve, automatically regulate the pressure on each oil pocket fuel feeding road, flow, come the free size drift, making the pairing workbench floatation volume of each oil pocket is stable putting, the assurance working table movement is steady, reaches the purpose of ultraprecise processing.
The present invention can guarantee that working table movement is steady, reaches the purpose of ultraprecise processing.

The specific embodiment
Shown in Fig. 1,3, a kind of ring-shaped guide rail 12 of vertical lathe, it comprises a circle static pressure oil pocket 1 and a hydraulic circuit 18 of the annular array that is located on the ring-shaped guide rail, described hydraulic circuit 18 is connected with static pressure oil pocket 1; Be provided with noncontact thermocouple type micron order temperature sensor 3 and noncontact induction type micron order displacement transducer 2 in the described static pressure oil pocket 1; Described noncontact thermocouple type micron order temperature sensor 3 is connected with control system 17 by data wire respectively with noncontact induction type micron order displacement transducer 2; Described hydraulic circuit 18 is provided with proportional flow adjustable valve 15 and proportional pressure valve 16; Described control system 17 is connected respectively with proportional pressure valve 16 with proportional flow adjustable valve 15 by data wire.
The principle of the present invention in the machined into process is as follows: shown in Fig. 1～3, hydraulic oil enters static pressure oil pocket 1 by the oil inlet pipe 11 arrival oil-ins 4 of hydraulic circuit 18, in each static pressure oil pocket 1, produce static pressure, corresponding work top 7 is upwards floated, the floatation volume that its each oil pocket 1 corresponding work top 7 makes progress, the oil temperature is by displacement transducer 2, temperature sensor 3 is converted into the signal of telecommunication, metering-in control system 17, through passing to proportional flow adjustable valve 15 after the conversion calculating, proportional pressure valve 16, control hydraulic circuit 18 enters into the flow of the hydraulic oil of static pressure oil pocket 1, pressure makes the floatation volume of workbench 7 integral body be stabilized in a standard value.This vertical lathe spindle system drives workbench 7 by oil motor 13 by driving shaft 9, and the radial location of workbench 7 is supported with rotation and mainly finished by hydrostatic bearing 10.Because of the fit clearance of whole active face is very little, the size drift that is caused by variations in temperature will be a problem of can not ignore, and the oil return opening 5 of each static pressure oil pocket 1 is arranged on the oil pocket outer, be unimpeded in order to guarantee oil return, the returning-oil temperature unanimity.
