A body of the rotary shaft is hollow, the tail portion of the rotary shaft is provided with a flange, the rotary shaft balances the axial load of the rotary shaft through air thrust of two sides of the flange, the middle portion of the rotary shaft is provided with an imbedded electrochemical copper mouse cage, the front end of a shaft body is provided with a tapered hole which is concentric with the shaft body, a spring chuck is mounted in the hole, and a sliding automatic locking mechanism is arranged in a hollow inner hole of the rotary shaft. The rotary shaft of the structure adopts the middle portion to be provided with the imbedded electrochemical copper mouse cage, and the mouse cage and a rotary body have high concentricity and symmetry. The rotary shaft is hollow, the inside is provided with the sliding automatic locking mechanism, and the rotary shaft has the advantages of achieving fast replacement of tools, maintaining higher clamp precision and providing higher balance for high-speed operation.
Description
Technical field
The utility model relates to a kind of rotating shaft of air bearing electricity main shaft, is mainly used in the electric main shaft of wiring board boring usefulness.
Background technology
Because the development of wiring board technology, people more and more want to enhance productivity, also to improve the quality of processing simultaneously, require also more and more littler to the aperture on the circuit, so just the motor to the processing aperture has had higher requirement, and being included on the rotating speed smoothness of operation that requires higher, motor can be good, motor is little etc. in the swing that runs up.
At present at the machine shaft of adapted on the market, the adhesion of copper is poor, concentricity is low, quality is heavy, and the running balance is poor, can't realize that ultrahigh speed turns round.The copper mouse cage when ultrahigh speed turns round, can occur and cause motor to be scrapped, also have the bigger amplitude of oscillation simultaneously and can't realize aperture processing, cause working (machining) efficiency low because rotating speed is low simultaneously because of centrifugal force flies out.Can't realize high speed, high-accuracy, high efficiency processing purpose.
The utility model content
At above-mentioned technological deficiency, the utility model aims to provide a kind of rotating shaft that is used for air bearing electricity main shaft that solves the technical problem of circuit-board drilling micro hole and can promote working (machining) efficiency.
For realizing this purpose, scheme of the present utility model is: a kind of rotating shaft of air bearing electricity main shaft, the body of described rotating shaft is a hollow, afterbody in rotating shaft is provided with flange, rotating shaft is by the axial load of the air thrust-balancing rotating shaft of two faces of flange, and there is embedded electrochemical copper mouse cage at the middle part of rotating shaft, and the axis body front end has a tapered hole concentric with axis body, one collet is housed in the hole, in the hollow endoporus of rotating shaft, is provided with the slidingtype automatic locking mechanism.
As improvement, the structure of described automatic locking mechanism is: the axis body endoporus is equipped with sliding nut, and sliding nut is connected with the collet of axis body front end by a connecting bolt, between sliding nut and collet butterfly spring is installed.
The rotating shaft of this structure adopts the middle part that embedded electrochemical copper mouse cage is arranged, and mouse cage and rotary body have very high concentricity and symmetry.Rotating shaft hollow, in be provided with the slidingtype automatic locking mechanism, but the quick replacing of implementation tool and keep higher clamping precision provides higher balance for running up.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the body 2 of the rotating shaft of a kind of air bearing electricity main shaft of the present utility model is a hollow 4, afterbody in rotating shaft has flange 1, rotating shaft can be by flange the axial load of air thrust-balancing rotating shaft of two faces, the middle part of rotating shaft has down to go into formula electrochemical copper mouse cage 3, the axis body front end has a tapered hole concentric with axis body, one collet 7 is housed in the hole, in the hollow endoporus of rotating shaft, be provided with the slidingtype automatic locking mechanism, its structure is that the axis body endoporus is equipped with sliding nut 5, sliding nut is connected with the collet of axis body front end by a connecting bolt 6, butterfly spring 8 is installed between sliding nut and collet, promote the switching that sliding nut just can be realized collet with thrust, change process tool fast, kept good clamping effect simultaneously.
