The specific embodiment
Fig. 1 is the schematic cross sectional views that hole processes the front guider 201 of boring cutter according to an embodiment of the invention.As can be seen from Figure 1, before processing boring cutter in hole of the present invention, guider 201 comprises:
The cover 101 coordinating with boring cutter bar 202, it is the projection of annulus that the outer surface of cover 101 has radial section, projection extends axially and the axis of projection and the dead in line of cover 101 along cover 101, the outer surface that the outer surface of cover 101 is socketed with the outer ring of 102, two bearings 102 of two bearings is set with the bearing 103 that can be fixedly mounted on fixture.
The inner ring axially parallel of two bearings 102 and clamp projection, the outer ring axially parallel of two bearings 102 and clamp spacer 104, the outer surface of spacer 104 contacts with the inner surface of bearing 103, and projection and the common axial distance that limits 102, two bearings of spacer 104 are definite value.
Bearing 103 bottoms are provided with end cap 105, end cap 105 is fixedly connected with bearing 103, and contact with cover 101 with the outer ring of the bearing 102 of bearing 103 bottoms, bearing 103 upper ends are provided with cover plate 106, cover plate 106 is fixedly connected with bearing 103, and contacts with cover 101 with the outer ring of the bearing 102 of bearing 103 upper ends.
End cap 105, bearing 103, overlap 101, have the first sealing ring 107 that is pressed on 105 of cover 101 and end caps in cavity that the bearing of bearing 103 bottoms forms; Cover plate 106, bearing 103, overlap 101, have the second sealing ring 108 that is pressed on 106 of cover 101 and cover plates in cavity that the bearing of bearing 103 heads forms.
This design makes when fine finishining is carried out in hole, boring cutter bar 202 can be with cover 101 matched in clearance of this device, when boring cutter bar 202 rotates, owing to overlapping 101 outer surface, be socketed with bearing 102, cover 101 can be followed boring cutter bar 202 High Rotation Speeds, now front guider has played to boring cutter bar 202 effect of supporting and leading, and has reduced the radial vibration of boring cutter 203 in the process of hole, has guaranteed the machining accuracy in hole.In addition, this device volume is little, easy for installation, overlap 101 hole size can according to boring cutter bar axially and radial dimension determine.
In the embodiment described in Fig. 1, overlap 101 outer surface and can be socketed with the protective cover 109 that the shape with cover plate 106 adapts to, protective cover 109 can by screw with overlap 101 and be fixedly connected with.This design can prevent that dust and other impurities from falling into this device, and this device is played a protective role.
In the embodiment described in Fig. 1,103 of cover plate 106 and bearings can compress adjusting pad 110, and cover plate 106, adjusting pad 110, bearing 103 can be bolted.Described adjusting pad 110 can be steel packing ring.This can adjust its thickness by grinding adjusting pad 110 when whole device is installed, thereby avoids the installation difficulty that causes because of part's machining errors.
The part using in above-described embodiment except the first sealing ring 107, the second sealing ring 108 be standard component, bearing 102 is outsourcing piece, all the other are parts peculiar, need specialized designs and making.
Fig. 2 is the assembling schematic diagram of the front guider 201 of the processing boring cutter of hole shown in Fig. 1 and boring cutter bar 202.This device is a self-contained unit, before using processing boring cutter in hole of the present invention during guider 201, need to by bearing 103, be fixed on (as being fastened on fixture by four bolts and two pins) on fixture first by the installation of this device, remain transfixion.When adding man-hour to workpiece, boring cutter bar 202 high speed rotating, drive 203 pairs of workpiece of boring cutter to process, drive cover 101 high speed rotating together simultaneously, cover 101 is supported on fixed bearing 103 by bearing 102, now before the processing of hole of the present invention, 201 pairs of boring cutter bars 202 of guider have played the effect of supporting and leading, and have reduced the radial vibration of boring cutter 203 in the process of hole, have guaranteed the machining accuracy in hole.In addition, before boring cutter bar 202 starts to rotate, can splash into lubricating oil, the wearing and tearing that cause to reduce the two when highly rotating to cover 101 and 202 of boring cutter bars.
In the above-described embodiments, on end cap 105 and the first sealing ring 107, all can be provided with the end cap oil-feed through hole communicating, on cover plate 106 and the second sealing ring 108, all can be provided with the cover plate oil-feed through hole communicating.Wherein, end cap oil-feed through hole can be N, and cover plate oil-feed through hole can be M, and N, M are more than or equal to 1 natural number.This design makes staff to bearing 102, to splash into lubricating oil from oil-feed through hole, guarantees the normal operation of bearing 102, reduces the wearing and tearing of bearing 102; And it is a plurality of making end cap oil-feed through hole, and cover plate oil-feed through hole is a plurality of, can more fully to bearing 102, play lubrication so that staff splashes into lubricating oil from all directions, reduce its wearing and tearing.
In another embodiment of the present invention, bearing 102 can be rolling bearing.
So far, those skilled in the art will recognize that, although detailed, illustrate and described a plurality of exemplary embodiment of the present invention herein, but, without departing from the spirit and scope of the present invention, still can directly determine or derive many other modification or the modification that meets the principle of the invention according to content disclosed by the invention.Therefore, scope of the present invention should be understood and regard as and cover all these other modification or modifications.
