Abstract
The invention pertains to the mechanical processing field, in particular to a hydrostatic guideway with controllable oil film thickness and a regulating method thereof. The hydrostatic guideway comprises a sliding block and a fixing base and is characterized in that: the sliding block is an elastic structure which can elastically deform to lead the oil film clearance between the sliding block and the fixing base to be controllable, so as to regulate the thickness of the oil film; the clearance between the sliding block and the fixing base is regulated to be zero when having no hydraulic oil; when the hydraulic oil enters an oil recess, the oil film clearance is formed between the sliding block and the fixing base by utilizing the elastic deformation caused by the elastic structure, and the oil film is established. As the hydrostatic guideway can regulate the elastic deformation degree of the sliding block, the size of the oil recess and the pressure of the hydraulic oil, the oil film clearance after the elastic deformation can be regulated to be quite small, thereby the thickness of the oil film can be quite small and the rigidity of the hydrostatic guideway can be quite high. The hydrostatic guideway has the advantages of reasonable structure, controllable oil film clearance, greatly enhanced rigidity and being convenient for manufacturing.
Description
The invention belongs to field of mechanical manufacture technology, specifically is adjustable hydrostatic slideway of a kind of oil slick thickness and regulating method thereof.
Background technique
Hydrostatic slideway has long, precision advantages of higher of life-span in the mechanical field extensive application because of it, and it generally is made up of slide block and fixed base, but owing between slide block and the fixed base across oil film, so its rigidity is not as slide guide, because the rigidity of hydrostatic slideway depends on the size of oil slick thickness, oil slick thickness is big more, and rigidity is poor more, oil slick thickness is more little, rigidity is good more, and oil slick thickness depends on the gap between slide block and the fixed base, and the gap is more little, then oil slick thickness is more little, and rigidity is also just good more.The manufacturing and the assembly technology level of each part are depended in the gap of hydrostatic slideway slide block and fixed base, but also will consider factors such as thermal distortion in use.Generally speaking, gap control is more than greater than 0.02mm.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, a kind of more reasonable structure is provided, makes the hydrostatic slideway simple, that the better oil slick thickness of rigidity is adjustable, and disclose its regulating method.
Technological scheme of the present invention is as follows: the hydrostatic slideway that a kind of oil slick thickness is adjustable, comprise slide block and fixed base, many opposed static pressure oil pockets of group and corresponding oil input channel are arranged on the slide block relative with fixed base, between slide block and the fixed base oil clearance is arranged, it is characterized in that: slide block is an elastomer, can produce resiliently deformable and make oil clearance adjustable, thereby regulate oil slick thickness.
The present invention also can be provided with elastomer between slide block and each static pressure oil pocket, can produce resiliently deformable and make oil clearance adjustable, thereby regulate oil slick thickness.
Regulating method of the present invention is: with the slider designs of hydrostatic slideway is elastic structure; Gap between slide block and fixed base is adjusted to zero when not having pressure oil; After pressure oil enters oil pocket, utilize elastic structure generation resiliently deformable to make between slide block and the fixed base and form oil clearance, and set up oil film.
The present invention so just can make hydrostatic slideway reach very high rigidity because the pressure height of elastic deformation level that can adjusting slider and oil pocket size and pressure oil so can be provided with the oil clearance after the resiliently deformable very little, also be that oil slick thickness is very little.The present invention is rational in infrastructure, and oil clearance can regulate, and easily manufactured has increased the rigidity of hydrostatic slideway greatly.

Fig. 2 is embodiment of the invention hydrostatic slideway structural representation behind logical pressure oil.
Embodiment
Embodiment
As Fig. 1, shown in 2, the hydrostatic slideway that a kind of oil slick thickness is adjustable, form by fixed base 1 and slide block 2, many opposed static pressure oil pockets 3 of group and corresponding oil input channels are arranged on the slide block 2 relative with fixed base 1, oil clearance 4 is arranged between slide block and the fixed base, it is characterized in that: slide block 2 is elastic slide block, when pressure oil does not feed, between fixed base 1 and the elastic slide block 2 (as shown in Figure 1) very close to each other, when pressure oil enters each static pressure oil pocket 3, because the resiliently deformable of elastic slide block 2 self, each static pressure oil pocket 3 produces oil clearance 4 and forms oil film (as shown in Figure 2) with fixed base 1 opposite position on the slide block, because the resiliently deformable of slide block 2 can be provided with, and the pressure of pressure oil and oil pocket size also can artificially be provided with, so the gap that produces owing to resiliently deformable also is that oil slick thickness also can be controlled, thereby reach the purpose of controlling and improving rigidity.
