Accompanying drawing explanation
Fig. 1 is the scheme of installation of conical handle cutter removing device of the present utility model;
Fig. 2 is the structural representation of conical handle cutter removing device of the present utility model;
Fig. 3 is the structural representation that lathe of the present utility model supports firmware.
Detailed description of the invention
Refer to Fig. 1 and 2, it is respectively scheme of installation and the structural representation of conical handle cutter removing device of the present utility model.Conical handle cutter removing device of the present utility model comprises taper shank and supports firmware 11, lathe to firmware 12 and nut 15.Wherein, this lathe supports firmware 12 and is set on machine tool chief axis 4 outer surface, and taper shank supports firmware 11 and supports firmware 12 and machine tool chief axis 4 through lathe simultaneously, is fixed on lathe supports on firmware 12 with nut 15.This taper shank supports the end that firmware 11 can prop up the taper shank 5 of cutter, is ejected.
Conical handle cutter removing device in the present embodiment is applied on drilling machine, this drilling machine comprises lathe headstock 2, be fixed on the machine tool chief axis end cap 3 on lathe headstock 2, machine tool chief axis 4 is arranged on lathe headstock 2, can relative to lathe headstock 2 along its axially-movable.Machine tool chief axis is axially arranged with internal taper hole along it, and the taper shank 5 of drill bit inserts this internal taper hole and fixes.In order to convenient disassembly, be generally provided with radial removal hole 41 in machine tool chief axis, the end of taper shank 5 is stretched in this removal hole 41.When needing with traditional manual type dismounting drill bit, voussoir can be inserted in this removal hole 41, and beaing with hammer, making voussoir prop up the end of taper shank 5, and oppressing taper shank 5 and deviate from outside internal taper hole vertically.
It is bearing pin that taper shank of the present utility model supports firmware 11, and its diameter is slightly less than the diameter of removal hole 41, when this taper shank radially inserts this removal hole 41 to firmware 11, its outer surface can with the ends contact of taper shank 5, and leave the space moved along the radial.When radially (i.e. the axis of machine tool chief axis) is mobile to firmware 11 for this taper shank, taper shank 5 can be propped up and oppress its axis along machine tool chief axis outwards to deviate from.In addition, the axle body of bearing pin can not have tapering, can have certain taper yet.In other implementations, taper shank supports firmware 11 and may not be bearing pin, but other shapes, as square strip.Taper shank supports the position that contacts with taper shank 5 of firmware 11 can be set to plane, groove or projection, or the shape corresponding with the end of taper shank 5, makes it prop up better and the end of oppressing taper shank 5 makes it deviate from.
Refer to Fig. 3, it is the structural representation that lathe of the present utility model supports firmware 12.It is cylindric that this lathe supports firmware 12, and it is set on the outer surface of machine tool chief axis 4, and its one end is provided with circular radial protrusion portion, and this radial protrusion portion can prop up the standing part of machine tool chief axis end cap 3 or other lathes.Lathe supports smooth between the inwall of firmware 12 and the outer wall of machine tool chief axis 4 being close to, can slightly relative movement.Lathe supports firmware 12 and is provided with radial installing hole 13, supports firmware 11 and inserts, and be spun on nut 15 one or both ends that taper shank supports firmware 11 for taper shank, taper shank is supported firmware 12 to firmware 11 and lathe and is fixedly connected with.In other embodiments, it also can be other shapes that this lathe supports firmware 12, as having the sheet of radian, two pieces of sheets are close to machine tool chief axis respectively, and be fixedly connected with the two ends of taper shank fixture 11 respectively, or be semi-circular cylindrical, to reduce materials and weight.This lathe supports firmware 12 and be fixedly connected with taper shank also can not support one end of firmware 11 between firmware 11 nut 14 by being spun on taper shank, but the fixing hole arranged on lathe fixture along machine tool chief axis axis, screw is screwed in this fixing hole and taper shank is close to fixing to the outer wall of firmware 11 and the inwall of installing hole 13.
Further, support between firmware 12 at nut 14 and lathe and be provided with bullet pad 15, prevent from loosening, fixed effect is better.Support the head of firmware 11 and lathe at nut 14, taper shank to support between firmware 12 and be equipped with plain cushion 16, reduce pressure, prevent wearing and tearing.
Lathe in use, is supported firmware 12 and is set on machine tool chief axis 4 by conical handle cutter removing device of the present utility model, then taper shank is supported firmware 11 and inserts in installing hole 13 and removal hole 41, and be tightened with nut 14.When needs use drilling machine processing work, machine tool chief axis 4 is outwards movement vertically, and conical handle cutter removing device moves along with machine tool chief axis 4.When cutter unloads by needs, shake machine tool chief axis handle, moves machine tool chief axis 4 to the direction of lathe headstock 2 vertically, makes lathe support firmware 12 and prop up machine tool chief axis end cap 3.Can slightly relatively move axially by machine tool chief axis in removal hole 41 because taper shank supports firmware 11, and lathe supports between firmware 12 with machine tool chief axis 4 as slidably to contact, therefore when lathe is after firmware 12 props up machine tool chief axis end cap 3 and be fixing, machine tool chief axis 4 still can move to lathe headstock 2, now taper shank 5 is followed machine tool chief axis 4 and is moved, its end props up taper shank and supports firmware 11, be fixedly connected with by nut 14 to firmware with lathe because taper shank supports firmware 11, therefore it can not move to the direction of lathe headstock 2, taper shank supports firmware 11 and therefore props up taper shank 5, and it is produced to the power of a compressing, taper shank 5 is deviate to the opposite direction of machine tool chief axis 4 movement, complete cutter dismounting.
Conical handle cutter removing device of the present utility model, simple and compact for structure, with low cost, taper-shank cutter can be dismantled easily, alleviate labour intensity, and can with lathe work, without the need to repeatedly installing in use, reducing and produce non-cutting time, also without the need to making a change machine tool structure, not affecting the precision of machine tool chief axis, main shaft bearing.
The utility model is not limited to above-mentioned embodiment, if do not depart from spirit and scope of the present utility model to various change of the present utility model or distortion, if these are changed and distortion belongs within claim of the present utility model and equivalent technologies scope, then the utility model is also intended to comprise these changes and distortion.
