Utility model purpose: in order to solve the deficiency that exists among the background art, so the utility model provides a main shaft mount pad dress aircraft nose.
The technical scheme is as follows: main shaft mount pad dress aircraft nose, including Z axle straight line slip table, main shaft mount pad, spindle motor and main shaft body, the main shaft mount pad is the linear slip on Z axle straight line slip table, the rotation room has been seted up downwards at main shaft mount pad center, it has the bearing frame to rotate the room and cast close to the top an organic whole, install the bearing in the bearing frame, the main shaft body rotates with the bearing and is connected, it installs the closing cap to rotate the room top, the groove of stepping down has been seted up at the closing cap center, the closing cap top is the annular array several air inlet ducts, spindle motor's output shaft passes the groove of stepping down and is connected with this body of main shaft, it is equipped with the heliciform air-out groove to rotate the indoor.
Preferably, the surface of the inner wall of the sealing cover is provided with a plurality of reinforcing ribs.
Preferably, the air outlet groove is outwards provided with a chamfer.
Preferably, the air inlet groove is internally provided with a chamfer.
Preferably, a filter screen is arranged in the air inlet tank.
The utility model discloses realize following beneficial effect:
1. the utility model discloses a top at the rotation room is equipped with the closing cap and can plays dirt-proof effect, has effectually prevented that the dust from falling into the bearing frame in, causes the relatively poor condition of rotation to appear in the pivot of being connected with the bearing.
2. The utility model discloses a set up the intake stack in the top of closing cap and be equipped with out the wind groove at the inner wall that rotates the room, can realize better heat dissipation to make the main shaft body stabilize the rotation, improved the machining precision.
Drawings
The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the present disclosure and together with the description, serve to explain the principles of the disclosure.
Fig. 1 is a schematic view of the overall structure provided by the present invention.
Fig. 2 is a schematic view of the structure of the sealing cover provided by the present invention.
In the figure: the novel bearing comprises a Z-axis linear sliding table 1, a main shaft mounting seat 2, a main shaft motor 3, a main shaft body 4, a rotating chamber 5, a bearing seat 6, a bearing 7, a yielding groove 8, an air outlet groove 9, a sealing cover 10, a reinforcing rib 11, an air inlet groove 12 and a filter screen 13.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Examples
Referring to fig. 1-2, a main shaft mounting seat is provided with a machine head, which comprises a Z-axis linear sliding table, a main shaft mounting seat, a main shaft motor and a main shaft body, wherein the main shaft mounting seat linearly slides on the Z-axis linear sliding table, a rotating chamber is downwards arranged at the center of the main shaft mounting seat, the rotating chamber is close to the top and integrally cast into a bearing seat, a bearing is arranged in the bearing seat, the main shaft body is rotatably connected with the bearing, a sealing cover is arranged at the top of the rotating chamber, a abdicating groove is formed in the center of the sealing cover, a plurality of air inlet grooves are annularly arrayed above the sealing cover, an output shaft of the main shaft motor penetrates through the abdicati.
The specific working principle is that the main shaft mounting seat slides on the Z-axis linear sliding table, the main shaft motor is used for driving the main shaft body to rotate, in the process of driving the main shaft body to rotate by the main shaft motor, a large amount of dust may fall on the bearing in the bearing seat to influence the main shaft body to realize stable rotation, so as to avoid the above situation, therefore, the top of the rotating chamber is provided with the sealing cover to isolate dust, a large amount of heat is generated when the main shaft motor drives the main shaft body to rotate, if the working time is long, the main shaft body is possibly affected, the machining precision is low, therefore, the air inlet grooves are arranged above the sealing cover in an annular array mode to supply air to the rotating chamber, the spiral air outlet grooves are formed in the inner wall of the rotating chamber to exhaust air to the outside, and the spiral air outlet grooves need to penetrate through the rotating chamber.
The surface of the inner wall of the sealing cover is provided with a plurality of reinforcing ribs, so that the bearing capacity of the sealing cover can be enhanced, and the sealing cover is protected by better realization.
The air outlet groove is outwards provided with a chamfer, so that the air outlet groove has an additional guiding function, and the air outlet efficiency of the air outlet groove is improved.
The air inlet groove is internally provided with a chamfer, so that the air inlet groove has an additional guiding function, and the air inlet efficiency of the air inlet groove is improved.
The air inlet groove is internally provided with a filter screen which can prevent dust in the air from entering the rotating chamber through the air inlet groove.
The above embodiments are only for illustrating the technical conception and the features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All changes and modifications that come within the spirit of the invention are desired to be protected.
