Abstract
The utility model discloses an aligning tool for a boring and milling lathe, which comprises an aligning rod. One end of the aligning rod is of an outer cone structure, and internal threads are arranged at a port of an outer cone; the other end of the aligning rod is of a circular truncated cone structure; an aligning sleeve is sleeved on a circular truncated cone; a gasket and an inner-hexagonal bolt are arranged at an outer port of the aligning sleeve; the inner-hexagonal bolt is in threaded connection with an axis hole of the circular truncated cone at the end head of the aligning rod; the distance between the gasket and a circular truncated cone through shoulder is larger than the axial length of the aligning sleeve; and the internal diameter of the aligning sleeve is larger than the external diameter of the circular truncated cone. The utility model has the beneficial effects that when a spindle rotating at a high speed drives the aligning sleeve to be close to the surface of a workpiece, and the aligning tool is not in contact with the surface of the workpiece, the aligning sleeve can rotate at a high speed along with the aligning rod; when being in contact with the surface of the workpiece, the aligning sleeve can carry out eccentric motion under the action of outside force and is reflected; and a machine tool operator can align the workpiece according to the critical state whether the aligning sleeve carries out the eccentric motion.
Description
Technical field
The utility model belongs to machinery manufacturing technology field, is specifically related to a kind of boring, milling machine centering instrument.
Background technology
Under the situation that requires to improve day by day at machining accuracy, location, the centering of part in process plays decisive action.Traditional alignment rod is under the machine tool chief axis inactive state, through machine tool chief axis move the convergence processing parts, locate in the slit of perusal alignment rod and processing parts, to confirm the centering precision.The precision of this aligning method depends on axiality and the cylindricity of self, the scale error of alignment rod head and afterbody, and bigger subjective uncertainty is arranged.In addition, after long-term the use, the lathe alignment rod can deform under external force, thereby the centering precision is reduced greatly.
Summary of the invention
The purpose of the utility model provides a kind of boring, milling machine centering instrument, solves prior art low difficult problem of centering precision in boring, milling machine process.
The technical scheme that the utility model adopted is, a kind of boring, milling machine centering instrument comprise alignment rod, and an end of alignment rod is outer wimble structure, and this outer cone port is provided with internal thread; The other end of alignment rod is a frustum cone structure; Be set with the centering cover on this round platform; The external port of centering cover is provided with pad and SOC.HD. cap screw; SOC.HD. cap screw is connected with the termination round platform axle center hole of alignment rod through screw thread, and pad and round platform pass through the axial length that the distance between the shoulder is overlapped greater than centering, and the internal diameter of centering cover is greater than the external diameter of round platform.
The beneficial effect of the utility model is; The centering cover is handled the back grinding through surface hardening, and dimensional tolerance is controlled in the 0.01mm, thereby has improved the centering precision and the wearability of centering instrument; Use this centering instrument, final centering precision reaches and is controlled in the 0.02mm.
Description of drawings
Fig. 1 is the centering instrument assembling sketch map of the utility model device under nature;
Fig. 2 is the centering instrument assembling sketch map under the utility model device busy state.
Among the figure, 1. SOC.HD. cap screw, 2. pad, 3. centering cover, 4. alignment rod.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is elaborated.
With reference to Fig. 1 and Fig. 2, the structure of the utility model device is, comprises alignment rod 4, and an end of alignment rod 4 is outer wimble structure, and this outer cone port is provided with internal thread, is connected with the machine tool chief axis inner cone and fixing through standard cone;
The other end of alignment rod 4 is a frustum cone structure; Be set with centering cover 3 on this round platform, the external port of centering cover 3 is provided with pad 2 and SOC.HD. cap screw 1, and SOC.HD. cap screw 1 is connected with the termination round platform axle center hole of alignment rod 4 through screw thread; Pad 2 is carried out restraint; The distance that pad 2 and round platform pass through between the shoulder is overlapped 3 axial length greater than centering, and the internal diameter of centering cover 3 is greater than the external diameter 3-5mm of alignment rod 4 round platforms, to guarantee the end play and the radial clearance of centering cover 3.
Fig. 1 is the centering instrument assembling sketch map under the nature; Alignment rod 4 matches with the machine tool chief axis inner cone through the right-hand member outer cone; Connect as one with machine tool chief axis through the right-hand member internal thread back that is connected with pull bar, move with machine tool chief axis thereby drive alignment rod 4; Centering cover 3 has the 3-5mm radial clearance with alignment rod 4; Centering cover 3 is fixed on the alignment rod 4 through the internal thread of alignment rod 4 left ends by pad 2, SOC.HD. cap screw 1.Because gapped between centering cover 3 and inside and outside circle that alignment rod 4 cooperates, so under the nature, centering cover 3 is because deadweight, interior round upper surface contacts with alignment rod 4, and interior round lower end is stayed in the gap entirely.
Fig. 2 is the centering instrument assembling sketch map under the duty, when machine tool chief axis drives alignment rod 4 and rotates at a high speed, under centering cover 3 self action of centrifugal force, can do concentric motion with alignment rod 4, does concentric motion thereby reach with machine tool chief axis.Through the contact situation of observation centering cover 3, and then realize the centering effect with surface of the work.
During the work of the utility model device, the centering instrument is connected with machine tool chief axis, drives the high speed rotation of centering instrument through the high speed rotary motion of machine tool chief axis.Because centering overlaps between the alignment rod that is connected with direct and machine tool chief axis the 3-5mm gap is arranged; When the centering cover is followed alignment rod when rotating at a high speed; Under self action of centrifugal force, the centering cover is done concentric motion with machine tool chief axis, and the machine operation person observes the situation that contacts (through judgements such as gap, sound) of centering cover and surface of the work; Thereby realize the effect of workpiece centering, the radius size of centering cover is exactly the distance of boring bar center to surface of the work.Cross with piece surface when the centering that runs up with lathe main shaft cover and to contact last time; The centering cover can be done eccentric motion under external force; When error is not more than fixed interval (FI) (maximal clearance of centering cover and alignment rod); The eccentric motion of centering cover can not exert an influence to alignment rod, thereby can not influence self precision of alignment rod yet.
