Abstract
The utility model discloses a static pressure rolling composite guide rail which comprises a slide rack for holding a ram, wherein a static pressure cavity is arranged in the slide rack; slide blocks are arranged in the static pressure cavity; and a row of pin rollers matched with the ram is arranged on the inner side of each slide block. According to the utility model, the slide blocks are arranged in the static pressure cavity, and solid granules, dust and the like cannot enter the static pressure cavity due to the action of oil pressure, so the composite guide rail can work in a severe industrial environment. The ram can move freely; and the composite guide rail is reliable in precision, good in precision maintenance and convenient to install and debug.
Description
Technical field
The utility model relates to a kind of static pressure rolling composite guide rails.
Background technology
The location clamping mode of machine ram mainly contains three kinds of forms, and a kind of is wedge and soft band; A kind of is roller slide block and soft band; A kind of is static pressure and soft band; These three kinds of modes are difficult to satisfy simultaneously heavy load and high-precision requirement, also are difficult to satisfy the requirement that fully reduces dynamic friction.
Under the situation of heavy load, ram is receiving to produce microdeformation on the force direction, causes the static pressure accent different with the gap of ram, has destroyed the static pressure environment; The gap of ram and static pressure resonator end surface itself, the vertical precision that under the situation of alternate stress, also can produce backlass and influence ram.
Wedge mode, slide block mode, under the situation of heavy load, can produce such as: softly be with impaired, ram contact-making surface to grind wound, slide block destroys, and each parts reaches fatigue limit and phenomenon such as impaired.
The wedge mode belongs to sliding friction, and is influential to the moving precision of lathe, defectiveness aspect the precision maintenance.
The utility model content
The purpose of the utility model is to provide a kind of static pressure rolling composite guide rails, makes ram movement freely, and precision is reliable, and it is good that precision keeps, and Installation and Debugging are convenient.
To achieve these goals, the technical scheme of the utility model is following:
Static pressure rolling composite guide rails is characterized in that, comprises the balladeur train that is used to place ram, and the inboard of said balladeur train is provided with the static pressure chamber, and said static pressure is provided with slide block in the chamber, and said slide block inboard is provided with the roller that a row matches with ram.
In a preferred embodiment of the utility model, said balladeur train is provided with and is used to connect static pressure chamber and extraneous static pressure oil pipe.
In the utility model, slide block is in the static pressure chamber, because the oil pressure effect, solid particle, dust etc. all can not get into, and can under the industrial environment of disliking example, work.
The utility model can move freely ram, and precision is reliable, and it is good that precision keeps, and Installation and Debugging are convenient.
The characteristics of the utility model can consult this case graphic and below better embodiment detailed description and obtain to be well understood to.
Description of drawings
Fig. 1 is the sketch map of the utility model.
Fig. 2 is the A place enlarged diagram of Fig. 1.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, further set forth the utility model below in conjunction with specific embodiment.
As illustrated in fig. 1 and 2, static pressure rolling composite guide rails mainly comprises balladeur train 100, is used to place ram 200, and ram 200 can slide along balladeur train 100.
The inboard of balladeur train 100 is provided with static pressure chamber 110, and balladeur train is provided with and is used to connect static pressure chamber 110 and extraneous static pressure oil pipe 120.The gap at static pressure chamber and ram applying position forms oil film.There is powerful hydraulic oil in the static pressure chamber, and dust, solid fine particle can't get into, and can effectively protect kinematic pair, and the anti-adverse environment ability is strong.
Be provided with slide block 130 in the static pressure chamber, a side of slide block is attached on the balladeur train, and the opposite side of slide block is provided with row's roller 131, and roller 131 matches with the outside of ram 200.Slide block contacts with ram and is sliding friction, reduce kinetic damping, and oil film has been avoided contacting between ram and balladeur train, and friction has been dropped to least limit.
Adjustment slide block pretightning force and with the depth of parallelism of ram, make ram guarantee geometric accuracy.Prevent that ram from tilting and micro-strain, make static pressure resonator end surface gap even, prevent leakage of oil and to produce pressure impaired.
The static pressure chamber forms the static pressure structure through the static line oil-feed, and the length in static pressure chamber can balance the heavy load of 70%-80% through calculating, and reduces the roller load, and avoiding increases mechanism's life-span to the weighing wounded of ram face.
The utility model structural rigidity is good, and debugging is convenient, reduces later maintenance work.Without periodic adjustment italic and slide block pretightning force, have good stability.It is very excellent that precision keeps.
More than show and described the advantage of basic principle, principal character and the utility model of the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The just principle of describing in the foregoing description and the specification of the utility model; The utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these variations and improvement all fall in the scope of the utility model that requires protection.The protection domain that the utility model requires is defined by appending claims and equivalent thereof.
