Description
Technical field
The utility model relates to air-floating apparatus, especially a kind of combined air flotation device of unaffected by disturbance of air pipes.
Background technique
Along with the continuous development of science and technology and machine building industry, people's creativity is also in continuous development, and the realization of gas suspension non-contact frictionless motion is exactly a good example.In a successful Application aspect the mechanical relative movement, its technology is quite ripe as the gas suspension technology for pneumatic bearing.Pneumatic bearing claims air-bearing again, is a kind of bearing, and it is by injecting pressurized gas in axocoel, and air film is just as two surface isolation of the relevant motion of oiling agent handle, thereby the air-bearing shafts that is enclosed within the bearing is suspended.Relative plain bearing, except non-contact does not have the friction relative movement, pneumatic bearing in higher running accuracy, at a high speed, reduce vibration, shock resistance height, increase the service life, reduce the superiority of polluting and increasing aspects such as axial/radial load capacity, make its firm just very fast development of appearance and obtain very wide application.
The gas suspension system rotates the field except can be applicable to air-bearing shafts, because its two surperficial non-contact frictionless characteristic, also can well be applied to air-bearing shafts and move axially the field, for example be that " air-float magneto motive friction-free suspension device " of CN200710071515.0 discloses and a kind of air-bearing shafts be applied in the air-floating apparatus in vertical frictionless motion field, wherein used two pneumatic bearing to realize the frictionless motion of in the vertical direction axle well at number of patent application.
On the other hand, be assurance air supporting, thereby must have the pressurized gas of certain pressure to enter generation air film between axle and the axle sleeve.Access way has two kinds, axle air feed or axle sleeve air feed.For axial motion, adopt the axle sleeve air feed usually, promptly pressurized gas is connected to the air supporting cover by tracheae, thus inboard pore discharge gas generation air film is overlapped in air supporting.This class mode is easy to connect, air consumption is little.If adopt the air-bearing shafts air feed, promptly pressurized gas inserts air-bearing shafts by tracheae, and air-bearing shafts outside pore discharges gas and the air supporting inner room produces air film.This mode is for axial motion, because air-bearing shafts is more much longer than the air supporting cover, must guarantee all has pore in the whole air supporting cover range of movement, so quantity of gas leakage is big, along with the length increase leakage rate of air-bearing shafts is very huge, cause to realize on the practical engineering application.Though but adopt which kind of mode air feed, pressurized gas all must connect by tracheae, when air-bearing shafts or air supporting cover axially move, tracheae also needs to take exercises, can cause the tracheae bending, because of tracheae has certain rigidity, this just may bring the influence of additional force.The additional force that is produced will inevitably be delivered to movement parts, thereby movement parts spatial position and motion are impacted.
Summary of the invention
In order to overcome the lower deficiency of tracheae drag effects, reliability that existing air-floating apparatus may exist, the utility model provides a kind of drag effects of effectively avoiding the air supporting assembly to produce with tracheae in the movement parts movement process, the combined air flotation device of the unaffected by disturbance of air pipes that reliability is good.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of combined air flotation device of unaffected by disturbance of air pipes, comprise one dimension air-bearing shafts and one dimension air supporting cover, described one dimension air supporting cover is sleeved on the described one dimension air-bearing shafts, described one dimension air supporting cover has two at least, described one dimension air supporting cover all is tightly connected with one dimension air storage cover, be gas storage chamber between described one dimension air storage cover and the one dimension air-bearing shafts, the axle center of described one dimension air-bearing shafts has gas-entered passageway, described gas-entered passageway is connected with the pressurized gas suction tude, described gas-entered passageway is communicated with described gas storage chamber, described gas storage chamber is provided with the air outlet, described air outlet is communicated with the suction port of each one dimension air supporting cover by connecting tracheae, described air-floating apparatus also comprises the one dimension fitting seat, described one dimension air-bearing shafts is installed on the described one dimension fitting seat, described one dimension fitting seat is fixedlyed connected with the one dimension mounting plate, described one dimension air storage cover or one dimension mounting plate and movement parts servo-actuated.
Described one dimension air storage cover is fixedlyed connected with connecting rod, described connecting rod is fixedlyed connected with the air supporting pulley, and the axle center of described air supporting pulley has inlet hole, and described inlet hole is communicated with the described tracheae that is connected, suit suspension rope on the described air supporting pulley, described movement parts is lifted on the described suspension rope.
Described one dimension mounting plate is fixedlyed connected with the two-dimensional gas empty boasting, described two-dimensional gas floating cover is sleeved on the described two-dimensional gas floating axle, described two-dimensional gas floating axle is fixedlyed connected with two-dimentional fitting seat, described two-dimentional fitting seat is fixedlyed connected with two-dimentional mounting plate, and described connection tracheae is communicated with the suction port of described two-dimensional gas empty boasting.
The beneficial effects of the utility model mainly show: air-floating apparatus is by the air-bearing shafts air feed, and movement parts is fixed on the fixed plate, therefore install that the crooked power that produces of suction tude only acts on the air-bearing shafts when mobile, and can not be delivered to fixed plate, thereby also can not produce the influence of additional force to the movement parts that is connected to fixed plate or air supporting pulley.Simultaneously, can realize all kinds of frictionless motions by the multilayer stack, and in the multi-deck combined process, not exist tracheae that the spatial position and the motion of movement parts are impacted all the time.
