Utility model content
For the deficiencies in the prior art, the purpose of this utility model is intended to provide a kind of dust-proof cover of speed electric rolling-ball main shaft, and the processing technology that it can simplify dust cap prevents that the chip that dust and part processing produce from entering into electric main shaft inside.
For achieving the above object, the utility model adopts following technical scheme:
The dust-proof cover of speed electric rolling-ball main shaft, comprises,
Dust cap, offers the through hole that the axle core of a power supply main shaft passes on this dust cap, dust cap inwall is provided with a recess, and the part of dust cap inwall between through hole and recess forms a guide face, guide face by recess towards through hole sloping inwardly gradually; On dust cap, be provided with one by its outer surface conducting the inlet channel to recess;
Ring air parcel, it is positioned at dust cap inside and is embedded in recess in friction tight mode, the outer surface of this ring air parcel offers a ring-type collecting tray being communicated with inlet channel, on ring air parcel, be uniformly distributed with multiple ventholes, one end of the plurality of venthole is communicated with ring-type collecting tray, and the other end extends to the end face of ring air parcel near guide face.
On dust cap, be provided with a radial hole radially extending along it and along its axially extended axial hole, the conducting of radial hole medial end extends to the side of dust cap to ring-type collecting tray, outboard end, end face, the other end that axial hole one end extends to dust cap are communicated with radial hole, the outboard end of radial hole is filled with a seal plug, and radial hole and axial hole form inlet channel.
The beneficial effects of the utility model are:
Than prior art, dust-proof cover processing technology of the present utility model is simple, especially lower to the dimension precision requirement of the through hole passing for main shaft thereon, and, the chip that adopts air seal can effectively prevent that dust and part processing from producing enters into electric main shaft inside, the service life of having improved electric main shaft.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Wherein: 10, dust cap; 11, through hole; 12, recess; 13, guide face; 14, radial hole; 15, seal plug; 16, axial hole; 20, ring air parcel; 21, ring-type collecting tray; 22, venthole.
The specific embodiment
Below, by reference to the accompanying drawings and the specific embodiment, the utility model is described further:
As shown in Figure 1, for the dust-proof cover of a kind of speed electric rolling-ball main shaft of the present utility model, it comprises dust cap 10 and ring air parcel 20, wherein, dust cap 10 tops offer the through hole 11 that the axle core of a power supply main shaft passes, the intracavity sidewall of dust cap 10 is provided with a recess 12 that is positioned at through hole 11 belows, the part of the sidewall of dust cap 10 inner chambers between through hole 11 and recess 12 forms the guide face 13 of an inclination, concrete is, this guide face 13 is by sloping inwardly gradually on lower, namely by recess 12 to through hole 11 sloping inwardly gradually, on dust cap 10, be also provided with the inlet channel composition of a conducting to recess 12, inlet channel outboard end opening is used for being communicated with extraneous high pressure origin.Ring air parcel 20 is arranged on dust cap 10 inside, and concrete is to be embedded in recess 12 in friction tight mode, and tight fit is the usually said interference fits of field of machining or interference fit; The outer surface of ring air parcel 20 offers a ring-type collecting tray 21 around its circumferencial direction, this ring-type collecting tray 21 is communicated with the inlet channel on dust cap 10, on ring air parcel 20, be also provided with multiple along its axially extended venthole 22, the plurality of venthole 22 is uniformly distributed at the circumferencial direction of ring air parcel 20, the bottom of venthole 22 is communicated with ring-type collecting tray 21, upper end extends to the upper surface of ring air parcel 20, the upper end that is venthole 22 extends to the end face of ring air parcel 20 near guide face 13, makes the outlet side of venthole 22 towards guide face 13.
