Description
Technical field
The utility model relates to electro spindle housing construction, is specifically related to a kind of housing construction of new-type air-floatation electro spindle.
Background technology
The body of existing installation air-flotation electric spindle is normally by the structure separate machined of mounted motor and air-bearing, corresponding body is also separately design, such processing cost is high, machining accuracy is low, also be difficult to get a desired effect in concrete installation process, the machining accuracy of the air-flotation electric spindle be arranged in body can not be ensured.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is the housing construction providing a kind of new-type air-floatation electro spindle, by body Integral design, improves the machining accuracy of air-flotation electric spindle.
For achieving the above object, the utility model passes through by the following technical solutions:
A kind of housing construction of new-type air-floatation electro spindle, comprise body, be provided with the inner chamber for air-floating main shaft cross-under in this body, inner chamber comprises bearing bore and the motor cavity for holding motor, bearing bore is positioned at the upper end of motor cavity and is communicated with the top of motor cavity, is provided with air-bearing in bearing bore; Body is provided with inlet channel, outlet passageway, one end of outlet passageway is communicated with inlet channel, and the other end of outlet passageway passes to bearing bore.
Preferably, bearing bore comprises upper bearing (metal) chamber and lower bearing chamber, is respectively arranged with upper and lower air-bearing in upper and lower bearing bore.
Preferably, outlet passageway is divided into the first outlet passageway and the second outlet passageway, and the first outlet passageway passes to upper bearing (metal) chamber, and the second outlet passageway passes to lower bearing chamber.
Preferably, body outer surface is provided with step surface, and motor cavity is positioned at the below of step surface, and bearing bore is positioned at the top of step surface.
Preferably, body outer surface is also provided with flat position, and flat position is positioned at the below of step surface.
The beneficial effects of the utility model are:
Compared to prior art, the housing construction of new-type air-floatation electro spindle of the present utility model, by motor cavity is integrated by whole body with air-bearing inner chamber, guarantee that motor cavity and air-bearing inner chamber have higher axiality, thus ensure that air-flotation electric spindle has higher rotating accuracy; Also guarantee that whole body has good rigidity in addition, ensure the machining accuracy of main shaft, this body outer surface has the design of flat position simultaneously, makes electro spindle add man-hour displacement maximum, meets process requirements.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view of Fig. 1.
Reference numeral: 10, body; 11, inlet channel; 20, motor cavity; 30, upper bearing (metal) chamber; 40, lower bearing chamber.
Detailed description of the invention
Below, by reference to the accompanying drawings and detailed description of the invention, the utility model is described further:
The housing construction of a kind of new-type air-floatation electro spindle as shown in Figure 1-2, comprise body 10, this body has inner chamber, and air-floating main shaft is connected in inner chamber; Concrete, inner chamber comprises bearing bore and the motor cavity 20 for holding motor, bearing bore is positioned at the upper end of motor cavity 20 and is communicated with the top of motor cavity 20, is provided with air-bearing in bearing bore, and two cavitys connections facilitate the installation of motor and main shaft and the running of rotating shaft; Certainly, body 10 is also provided with inlet channel 11, outlet passageway, inlet channel is used for providing gases at high pressure, for ensureing the normal operation of air-floating main shaft, and outlet passageway one end is communicated with inlet channel 11, the other end communicates with bearing bore, conveniently imports in bearing bore by gas, guarantees spindle operation.
Preferably, for improving the precision of air-floating main shaft, upper bearing (metal) chamber 30 and lower bearing chamber 40 can be set at bearing bore, conveniently in upper and lower bearing bore, upper and lower air-bearing be installed respectively, in order to increase the machining accuracy of air-floating main shaft.Certainly, in order to ensure the normal work of upper and lower air-bearing, needing in upper and lower bearing bore, to import gas respectively, therefore being respectively arranged with the first outlet passageway and the second outlet passageway, the gas in inlet channel is imported.
Preferably, body 10 outer surface is provided with step surface, body 10 can be divided into motor position and air-bearing position by step surface, concrete, motor cavity is positioned at below step surface, and bearing bore is positioned at more than step surface, this structure makes body more step up with coordinating of two chambeies, strengthen the rigidity of whole device, prevent the shake of main shaft, and then ensure the machining accuracy of main shaft.Further, the outer surface of part more than body step surface and air-bearing overcoat is also provided with flat position, specifically can be cubic flat position, electro spindle can be made to add the displacement of four direction in man-hour maximum, meet process requirements.
To one skilled in the art, according to technical scheme described above and design, other various corresponding change and deformation can be made, and all these change and deformation all should belong within the protection domain of the utility model claim.
