Abstract
The utility model relates to a combined static-pressure sliding component, which comprises a machine base, a movable rail, an immovable rail, a connecting bolt, and a tabletop. The movable rail and the table top form a worktable through the connecting bolt. The immovable rail and the base form a machine body through the connecting bolt. The machine body and the worktable are matched to form a sliding component. The bottom of the movable rail matching to the machine base and the side matching to the immovable rail are respectively provided with a plurality of symmetric static-pressure oil chambers. Oil feeding holes are arranged on the movable rail corresponding to the static-pressure oil chambers. During working, pressure oil when throttled respectively enters each oil chamber through the oil feeding holes and the worktable floats up so that the worktable during sliding is under pure liquid friction condition, and becomes a combined static-pressure sliding component with large bearing capacity, large speed range, long service life and high motion accuracy.
Description
Technical field
The utility model relates to a kind of combined type static pressure slide unit, belongs to the machine tool technology field.
Background technology
The static pressure slide unit is a kind of high accuracy functional part that is used for precision optical machinery and lathe manufacturing.Most of " V+-" or " V+V " open type guide rail structure that adopts of traditional lathe when static pressure floats, owing to be open architecture, easily produces hydro-planing during motion, guiding accuracy is poor.
Summary of the invention
The purpose of this utility model is to provide a kind of bearing capacity big, and velocity interval is wide, long service life, the combined type static pressure slide unit that running accuracy is high.
The technical solution of the utility model is: a kind of combined type static pressure slide unit is characterized in that: be made up of base, fixed guide, moving guide rail, table top and connecting bolt; Base and fixed guide are formed lathe bed by connecting bolt; Moving guide rail and table top are formed workbench by bolt; Lathe bed and the workbench composition slide unit that is complementary; On the bottom surface of moving guide rail and base coupling and with the side of fixed guide coupling on be processed with the static pressure oil pockets of many group symmetries respectively; On the corresponding moving guide rail of static pressure oil pocket, be provided with fuel feed hole.
Static pressure oil pocket on the described moving guide rail is the 2-8 group.
Described moving guide rail face angle is for being less than or equal to 90 °.
During the utility model work, the pressure oil after throttling enters each oil pocket respectively by fuel feed hole, and workbench is floated, thereby be in the neat liquid friction when workbench is slided, it is big to become a kind of bearing capacity, and velocity interval is big, long service life, the combined type static pressure slide unit that kinematic accuracy is high.
