Abstract
The invention provides a method for frictional self-locking clamping and cutting of a conical hole piece. The method comprises the following steps of: manufacturing a forge piece into the conical hole piece of which the surface roughness is less than or equal to Ra3.2 and the ratio of inner conical large and small heads is less than 10:1; connecting the tail end of a conical core rod of which the outer conical degree is equal to the inner conical degree of the conical hole piece and a discharge nut through threads; connecting internal threads which are formed at the tail ends of the conical core rod and a threaded pulling rod which is arranged on a main shaft hole of a lathe; connecting the head end of the conical core rod and a locking bolt through threads; centering and clamping the conical hole piece through the head end and the tail end of the conical core rod by using the conical degree of an inner hole of the conical hole piece; clamping a locking pressing plate by using the locking bolt; screwing the locking bolt by using a locking nut to fasten the conical hole piece; and programming cutting to move from a small hole end of the conical hole piece to a large hole end, and thus obtaining the molded conical hole piece. The method has the advantages that: quick clamping is realized; meter-hitting correction is not required; a processed workpiece is bright and clean in appearance; the trace of a connection knife is avoided; deformation and damage due to clamping are avoided; the coaxiality of inner and outer diameters is high; and production efficiency is high.
Description
Technical field
The invention belongs to machinery manufacturing technology field, particularly the method for kind of friction-type self-locking clamping cutting bellmouth spare.
Background technology
In machining, conventional lathe generally uses three-jaw or chuck that workpiece is connected adult with lathe spindle, realizes rotating synchronously, and the relative motion that produces through cutter and workpiece goes to reach the purpose of cutting workpiece again.
The wall degree is thin when meeting, the aperture is bigger; Internally, the higher taper work of external diameter concentricity requirement; When adopting three-jaw or chuck to carry out conventional clamping operation; Need through twice clamping that turns around; Therefore cause the cutter place that connects of workpiece to connect that tool marks mark, workpiece are pressed from both sides distortion, machined surface is crushed; And be difficult to guarantee the axiality in the inside and outside footpath of workpiece, production efficiency is low.
Summary of the invention
The object of the invention is the problem that exists in sum clamping cutting process, provides a kind of nothing to connect tool marks mark, workpiece not have distortion, does not have and crush, and outward appearance is bright and clean, the method that the friction-type self-locking clamping that inside and outside footpath axiality is high cuts bellmouth spare.
The method of friction-type self-locking clamping of the present invention cutting bellmouth spare, it processes surface roughness≤Ra3.2 with forging earlier, the bellmouth spare of the large and small head of inner cone＜10: 1.Get the conic mandrel bar that the internal taper of external taper and bellmouth spare causes; The conic mandrel bar tail end is connected with the discharging nut thread that is provided with threaded hole; The thread that is provided with on the internal thread of conic mandrel bar tail end setting and the lathe spindle hole is connected; The conic mandrel bar head end is threaded with clamping screw; Again with bellmouth spare through its hole taper through conic mandrel bar head end to the tail end clamping of feeling relieved; Locking pressure plate screws clamping screw through on the clamping screw card with locking nut, causes bellmouth spare fastening.And then move to big nose end through the programming cutting small bore end by bellmouth spare, promptly process moulding bellmouth spare.
The method of friction-type self-locking clamping cutting bellmouth spare of the present invention, its clamping is quick, need not to beat to show to proofread and correct, and the processing work outward appearance is bright and clean, nothing connects the tool marks mark, do not have the distortion nothing crushes, and inside and outside footpath axiality is high, the production efficiency height.

Fig. 2 is locking, discharging parts and the bellmouth spare of the method for friction-type self-locking clamping cutting bellmouth spare of the present invention, the cutaway view of conic mandrel bar assembled state;
Fig. 3 is the cutaway view of moulding bellmouth spare of the method for friction-type self-locking clamping of the present invention cutting bellmouth spare.
The specific embodiment
Below in conjunction with above-mentioned accompanying drawing instance, the method for friction-type self-locking clamping cutting bellmouth spare of the present invention is done progressive narration.
The instance of the method for friction-type self-locking clamping cutting bellmouth spare of the present invention includes bellmouth spare 1, conic mandrel bar 2, clamping screw 3, locking nut 4, locking pressure plate 5, threaded hole 6, discharging nut 8, moulding bellmouth spare 9.
The friction that produces between the method for friction-type self-locking clamping of the present invention cutting bellmouth spare, the taper hole that it utilizes bellmouth spare 1 and conic mandrel bar 2 reaches the purpose that the self-locking clamping cuts.It earlier processes surface roughness≤Ra3.2 with forging, and therefore the bellmouth spare 1 of the large and small head of inner cone＜10: 1 can satisfy the self-locking clamping and can guarantee that again bellmouth spare 1 reaches more than 70% with the spot that conic mandrel bar 2 cooperations contact.
For making conic mandrel bar 2 and lathe spindle concentric, get the conic mandrel bar 2 that the internal taper of external taper and bellmouth spare 1 causes, conic mandrel bar 2 tail ends are threaded with the discharging nut 7 that is provided with threaded hole 6.The thread that is provided with on the internal thread 8 of conic mandrel bar 2 tail end settings and the lathe spindle hole is connected, and it can be fastening with conic mandrel bar 2.Conic mandrel bar 2 head ends are threaded with clamping screw 3, with bellmouth spare 1 through its hole taper through head end to the tail end of conic mandrel bar 2 clamping of feeling relieved, thereby guarantee to produce friction between bellmouth spare 1 and the conic mandrel bar 2, reach the purpose of self-locking clamping.Locking pressure plate 5 through on clamping screw 3 cards, is screwed clamping screw 3 with locking nut 4, make bellmouth spare 1 fastening, and guarantee that play does not axially take place for it.Move to big nose end through the small bore end of programming cutting then by bellmouth spare 1; The axial thrust of utilizing axially cutting to produce is close to conic mandrel bar 2 with bellmouth spare 1, its stiction is increased, thereby avoid slippage; Reach smooth cut, promptly process moulding bellmouth spare 9.
When shedding moulding bellmouth spare 9, unclamp locking nut 4, remove locking pressure plate 5; Move threaded hole 6; Make 7 rotations of discharging nut, moulding bellmouth spare 9 can be unloaded from conic mandrel bar 2, accomplish the processing of friction-type self-locking clamping cutting bellmouth spare 1 of the present invention.
