Abstract
A shallow-oil-chamber cushion type pillow of a static pressure center frame comprises a pillow body, wherein the pillow body is of a rectangular structure, the upper end face of the pillow body is a regular arc surface and provided with eight grooves which are the same as the pillow body in shape and smaller than the pillow body in size, the eight grooves divide the pillow body into four parts through oil return grooves, each part is a rectangular oil cushion composed of two grooves, an oil chamber, an oil inlet hole and an oil sealing edge are machined in the upper end face of every rectangular oil cushion, and the lower end of the pillow body is a plane. The cushion type pillow improves the conditions of insufficient static pressure bearing capacity and strength caused by heavy loads and provides technical support for improving rotating accuracy and stability of the high-speed heavy-load static pressure center frame. In order to improve the bearing support and strength of the static pressure center frame, according to the tribology theory and a hydrostatic lubrication technology, the mode of combining theoretical analysis, numerical simulation and experiment research is adopted, and the optimum pillow oil chamber shape and the optimum oil chamber depth are obtained through optimization, so that the problems that the static pressure center frame is low in bearing accuracy and insufficient in strength are solved.
Description
technical field:
The present invention relates to a kind of holder watt, be specifically related to the holder watt of a kind of shallow oil pocket static-pressure central frame cushion.
background technology:
Application along with high-speed overload cutting technology, the supporting role of static-pressure central frame is also more and more obvious, yet the research of static-pressure central frame is still far from perfect both at home and abroad, static-pressure central frame often occurs that tribology lost efficacy and undercapacity problem, cause that operating efficiency reduces, machining accuracy declines, operation stability is poor, when serious, workpiece to be machined there will be and scraps phenomenon, causes machine breakdown, even bring casualties, to country, bring economic loss.
summary of the invention:
The present invention will solve now the low and poor difficult problem of operation stability of high-speed overload extreme operating condition precision, and the holder watt of a kind of shallow oil pocket static-pressure central frame cushion is provided.
The present invention solves the problems of the technologies described above the technical scheme of taking to be: the holder watt of a kind of shallow oil pocket static-pressure central frame cushion, comprise holder watt main body, it is characterized in that: holder watt main body is rectangular configuration, the upper surface of holder watt main body is that regular arc surface and end face are provided with eight and sizes identical with its shape and are less than the groove that holds in the palm watt main body, eight grooves are divided into four parts by oil-recovery tank by a holder watt main body, every part forms rectangle lubricating pad by two grooves, is processed with oil pocket, fuel feed hole and sealing oil edge on the upper surface of rectangle lubricating pad; The lower surface of holder watt main body is plane.
Between described rotational workpieces and rectangle lubricating pad, be provided with the gap of wedge shape.
A described holder watt main body is arranged on static-pressure central frame base.
The degree of depth of described oil pocket is 2mm-5mm.
The degree of depth of described oil pocket is 3mm.
The present invention compared with prior art has following beneficial effect: improve the situation of heavily loaded caused static pressure Lack of support and insufficient strength, for high-speed overload static pressure static-pressure central frame improves running accuracy and stability provides technical support.In order to improve static-pressure central frame bearing value and intensity, according to tribology theory and hydrostatic lubrication technology, adopt theory analysis, numerical simulation and the experimental study mode that combines, optimize and obtain best holder watt oil pocket shape and the oil pocket degree of depth, thereby solved a difficult problem for the low and undercapacity of static-pressure central frame supporting precision, for carrying and the speed-raising of numerical-control horizontal lathe provides a technical support.
accompanying drawing explanation:
Fig. 1 is the structural representation of holder watt main body.
Fig. 2 is structural representation of the present invention.
Fig. 3 is the profile of rectangle lubricating pad.
the specific embodiment:
In conjunction with each figure explanation, the holder watt of a kind of shallow oil pocket 1-1-1 static-pressure central frame cushion, comprise holder watt main body 1, it is characterized in that: holder watt main body 1 is rectangular configuration, the upper surface of holder watt main body 1 is that regular arc surface and end face are provided with eight and sizes identical with its shape and are less than the groove that holds in the palm watt main body 1, eight grooves are divided into four parts by oil-recovery tank 1-2 by holder watt main body 1, every part forms rectangle lubricating pad 1-1 by two grooves, is processed with oil pocket 1-1-1, fuel feed hole 1-1-2 and sealing oil edge 1-1-3 on the upper surface of rectangle lubricating pad 1-1; The lower surface of holder watt main body 1 is plane.The gap that is provided with wedge shape between described rotational workpieces 3 and rectangle lubricating pad 1-1, makes rotational workpieces 3 can produce dynamic and static pressure effect when rotating, reaches the lubricated effect of hybrid, has guaranteed the high-accuracy stable operation of static-pressure central frame.Described holder watt main body 1 is arranged on static-pressure central frame base 2.The degree of depth of described oil pocket 1-1-1 is 2mm-5mm.The degree of depth of described oil pocket 1-1-1 is 3mm.
Operation principle: four static-pressure central frame cushions of the present invention holder watt main body 1 is arranged on static-pressure central frame base 2, and workpiece to be machined 3 is arranged in static-pressure central frame cushion holder watt main body 1, inputs lubricating oil by oil pump to 2 fuel feed hole 1-1-2; While starting machine tool chief axis, machine tool chief axis High Rotation Speed, processing work 3 just and between static-pressure central frame cushion holder watt main body 1 has relative motion like this, thereby make to produce wedge gap between workpiece to be machined 3 and static-pressure central frame cushion holder watt main body 1, so just, met the condition that forms dynamic pressure, thereby reach the lubricated effect of hybrid, improved bearing capacity of the present invention and requirement of strength, and realized the high-accuracy stable operation of static-pressure central frame.
The present invention improves the situation of heavily loaded caused static pressure Lack of support and insufficient strength, for high-speed overload static pressure static-pressure central frame improves running accuracy and stability provides technical support.In order to improve static-pressure central frame bearing value and intensity, according to tribology theory and hydrostatic lubrication technology, adopt theory analysis, numerical simulation and the experimental study mode that combines, optimize and obtain best holder watt oil pocket 1-1-1 shape and the oil pocket 1-1-1 degree of depth, thereby solved a difficult problem for the low and undercapacity of static-pressure central frame supporting precision, for carrying and the speed-raising of numerical-control horizontal lathe provides a technical support.
