Abstract
The utility model discloses an air suspension shaft sleeve which comprises an external shell and an internal bushing, wherein a flange plate is arranged at the upper part of the external shell, two symmetrical small planes are arranged on the outer circle of the flange plate in a tangential manner, and at least one air inlet is arranged on each small plane and is communicated with an internal air channel arranged inside the shell; and a cylinder sleeve is arranged at the lower part of the external shell, an air inlet channel and an air outlet channel are arranged on the inner wall of the cylinder sleeve, and a throttling hole is arranged in the internal bushing. The air suspension shaft sleeve adopts the pressure-feed air bearing principle and adopts air for supporting, thus realizing no pollution and no friction as the air can be recycled and inexhaustible; and is matched with the shell of a high-speed running motor, thus replacing the traditional linear sliding rail, reducing the friction force during fast drilling, decreasing the load of a Z-axis motor, and leading the movement speed of the Z axis to be faster. The air suspension shaft sleeve realizes the improvement of processing accuracy while improving the efficiency, and greatly improves the processing efficiency of a circuit board.
Description
Technical field
The utility model relates to precision processing machine equipment, specifically is the boring axle sleeve of a kind of high speed and precision.
Background technique
Lifting along with productivity; The development of society, people never stopped the lifting of manufacturing efficiency, in the middle of some precision machining; Raise the efficiency and to cause the precise decreasing of processing, improve the problem that machining accuracy has become a lot of scientific and technical personnel's researchs when raise the efficiency again.At present, what adopt on the boring machine of high speed and precision is traditional linear slide rail, and this slide rail is installed more time-consuming; Machine designed structure more complicated; The space that identical movement travel needs is big, and frictional force is big during fast moving, and the faster frictional force of speed is big more; Also can generate heat, so work efficiency and precision can't improve.
The model utility content
To the problems referred to above, the utility model aims to provide a kind of circuit board that can solve and when drilling operating, not only improves drilling efficiency but also can improve borehole accuracy, reduces the air supporting axle sleeve of the vibrations of machine simultaneously.
For realizing this technical purpose; The scheme of the utility model is: a kind of air supporting axle sleeve; Be divided into external casing and neck bush two-part, it is characterized in that: the top of said external casing is a flange plate, and the cylindrical of flange plate is cut two facets of symmetry; Each facet all is provided with at least one suction port, and this suction port communicates with the inside air flue that enclosure is provided with; The bottom of said external casing is a cylinder sleeve, and inboard wall of cylinder liner has been provided with gas-entered passageway and exhaust passage, and neck bush is provided with throttling pore.
As preferably, the throttling pore on the said neck bush divides three rows to be provided with.
This air supporting axle sleeve has adopted the pressure-feed air bearing principle, supports and adopts air; Can recycle, resource is inexhaustible, has realized pollution-free, nothing friction; Cooperate the shell of the motor that runs up, substituted traditional linear slide rail, reduced the frictional force when rapid drilling; Reduced the load of Z axle motor simultaneously, made the movement velocity of Z axle faster.Improve machining accuracy when having realized raising the efficiency again.Improved the circuit board work efficiency greatly.
Description of drawings
Fig. 1 is the radial cross-section of the utility model.
Fig. 2 is the three-dimensional structure diagram of the utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is explained further details.
As illustrated in fig. 1 and 2, the utility model relates to a kind of air-bearing shafts nested structure.This axle sleeve is divided into external casing 1 and neck bush 2 two-part.External casing 1 top is a flange plate 3, and the cylindrical of flange plate 3 is cut two facets 4 of symmetry, and each facet all has a suction port 5, and suction port 5 communicates with inner air flue.The bottom of said external casing is a cylinder sleeve, and inboard wall of cylinder liner has gas-entered passageway 61 and exhaust passage 62.Three cribbings stream aperture 7 is arranged on the neck bush 2, form small intermittence, dam when pressurized gas flow into just to form with the shell of high-speed electric expreess locomotive; High-speed electric expreess locomotive just floats in the middle of this air supporting axle sleeve, moves up and down, because the rigidity of axle sleeve is fine; Be again gas lubrication, make high-speed electric expreess locomotive when moving up and down, not have frictional force, what speed can be very is fast; Do not generate heat yet, can guarantee the precision of machining accuracy.
The utility model has adopted the pressure-feed air bearing principle, supports and adopts air, can recycle; Resource is inexhaustible; Realize pollution-free, nothing friction, cooperated the shell of the motor that runs up, substituted traditional linear slide rail; Reduce the frictional force when rapid drilling, improved machining accuracy when having realized raising the efficiency again.Improved the circuit board work efficiency greatly.
This novel air supporting axle sleeve cooperates existing numerical control machining center, can realize per minute boring 600～700 hole counts, and machining accuracy is very high.
This air supporting axle sleeve structurally also might change neck bush into overcoat, and air inlet and exhaust are on main casing.
The above; Be merely the preferred embodiment of the utility model; Not in order to restriction the utility model, every technical spirit according to the utility model to any trickle modification that above embodiment did, be equal to replacement and improve, all should be included within the protection domain of the utility model technological scheme.
Claims (2)
1. air supporting axle sleeve; Be divided into external casing and neck bush two-part; It is characterized in that: the top of said external casing is a flange plate; The cylindrical of flange plate is cut two facets of symmetry, and each facet all is provided with at least one suction port, and this suction port communicates with the inside air flue that enclosure is provided with; The bottom of said external casing is a cylinder sleeve, and inboard wall of cylinder liner has been provided with gas-entered passageway and exhaust passage, and neck bush is provided with throttling pore.
