Abstract
The utility model belongs to numerical-control turn-milling bed technique field, is specifically related to a kind of vertical ram hydrostatic slideway for large-sized numerical control turn-miller.Because the vertical hydrostatic slideway of large-scale turnning and milling is secondary, by the irregular change in the size of cutting force, position and direction, hydrostatic slideway need bear the horizontal load of all directions and cutting force to the disturbing moment of guide rail, to the bearing capacity of oil film and the requirement of oil film rigidity very high, hydrostatic slideway technology to be applied on heavy type numerical control turn-miller on vertical guide rail by the utility model, because hydrostatic slideway has high rigidity, gapless feature, make vertical ram guide rail without wearing and tearing, improve guide rail shock absorption, improve the guiding accuracy of guide rail and the machining accuracy of part; And the utility model adopt a chamber one pump type current constant control closed hydrostatic slideway, the load of all directions can be born, can disturbing moment be born again, the closed hydrostatic slideway that oil film rigidity is high, improve the guiding accuracy of guide rail and the machining accuracy of part further, practical function is remarkable.
Description
Technical field
The invention belongs to numerical-control turn-milling bed technique field, be specifically related to a kind of vertical ram hydrostatic slideway for large-sized numerical control turn-miller.
Background technology
Quality of guide rail is to the rigidity of machine tool, machining accuracy and service life tool have a great impact, as the important step of Machine Tool Feeding System, dissimilar lathe is different to the requirement of guide rail, the guide rail of Digit Control Machine Tool requires high than the guide rail of machine tool, and do not vibrate when wishing its high speed feed, do not occur during low speed feeding creeping, highly sensitive, wearability is good, can long continuous operation under heavy loads, and precision stability is good, this is Machine Manufacture factory design lathe and lathe user when selecting lathe, the problem that must consider.At present, domestic large-scale vertical milling lathe ram moves and all adopts rail plate or skid composite guide rails, and this guide rail is owing to existing gap and mechanical friction, and guide rail easily produces wearing and tearing, and precision is low, and shock resistance is weak.
Summary of the invention
For solving the problems of the technologies described above, the invention provides that a kind of precision is high, shock-proof durable for large-sized numerical control turn-miller vertical ram hydrostatic slideway.
Because the vertical hydrostatic slideway of large-scale turnning and milling is secondary, by the irregular change in the size of cutting force, position and direction, hydrostatic slideway need bear the horizontal load of all directions and cutting force to the disturbing moment of guide rail, to the bearing capacity of oil film and the requirement of oil film rigidity very high, the invention provides a kind of load can bearing all directions, can disturbing moment be born again, the closed hydrostatic slideway that oil film rigidity is high, and adopt a chamber one pump type current constant control hydrostatic slideway.
The technical solution adopted in the present invention is: for the vertical ram hydrostatic slideway of large-sized numerical control turn-miller, comprise hydrostatic slideway plate 1, oil pocket 2 and swab case 3, swab case 3 is arranged on bottom hydrostatic slideway plate 1, hydrostatic slideway plate 1 is arranged oil pocket 2, it is characterized in that, every block hydrostatic slideway plate 1 arranges an oil pocket, 3 oil pockets 2 are set along guide rail direction, a upper oil chamber 2-1, two bottom oil pocket 2-2 and 2-3, the each cross section of ram 4 adopts 8 oil pockets, and each oil pocket 2 connects an oil pump, is a chamber one pump type current constant control hydrostatic slideway.
Described arranges 3 oil pockets 2 along guide rail direction, and two, bottom oil pocket 2-2 and 2-3 is arranged on same hydrostatic slideway plate 1.
The invention has the beneficial effects as follows: hydrostatic slideway technology to be applied on heavy type numerical control turn-miller on vertical guide rail, because hydrostatic slideway has high rigidity, gapless feature, make vertical ram guide rail without wearing and tearing, improve guide rail shock absorption, improve the guiding accuracy of guide rail and the machining accuracy of part; And the present invention adopt a chamber one pump type current constant control closed hydrostatic slideway, the load of all directions can be born, can disturbing moment be born again, the closed hydrostatic slideway that oil film rigidity is high, improve the guiding accuracy of guide rail and the machining accuracy of part further, practical function is remarkable.

Detailed description of the invention:
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment 1
As shown in Figure 1, for the vertical ram hydrostatic slideway of large-sized numerical control turn-miller, comprise hydrostatic slideway plate 1, oil pocket 2 and swab case 3, swab case 3 is arranged on bottom hydrostatic slideway plate 1, hydrostatic slideway plate 1 is arranged oil pocket 2, it is characterized in that, every block hydrostatic slideway plate 1 arranges an oil pocket, 3 oil pockets 2 are set, one, top oil pocket 2-1, two, bottom oil pocket 2-2 and 2-3 along guide rail direction.As shown in Figure 2, each cross section of ram 4 adopts 8 oil pockets, and each oil pocket connects an oil pump, is a chamber one pump type current constant control hydrostatic slideway.
Embodiment 2
Other structures are with embodiment 1, and described arranges 3 oil pockets 2 along guide rail direction, and two, bottom oil pocket 2-2 and 2-3 is arranged on same hydrostatic slideway plate 1.
Hydrostatic slideway plate contacts by static pressure oil film with ram gib face, belongs to fluid friction, is not mechanical friction, so excellent wear resistance, owing to having static pressure oil film in glade plane space, belongs to gapless driving, has precision high, oil film energy absorbing vibration, so shock resistance is good.
