Abstract
The invention discloses a clamping pulling tool used during slender shaft turning on a lathe. The clamping pulling tool comprises an outer sleeve, a core shaft and two clamping lobes, wherein the outer sleeve is fixed to a lathe tailstock sleeve through bolts; one end of the core shaft is mounted on a lathe tailstock through a thrust ball bearing capable of bearing axial load, and the other end of the core shaft is used for supporting the tip of a slender shaft; the two clamping lobes are used for clamping a semicircular sleeve of the slender shaft; a clamping sleeve sleeves the outer sides of the clamping lobes, and the clamping sleeve conveniently pushes the clamping lobes to tension the slender shaft; and the clamping sleeve and the core shaft are in threaded connection. According to the clamping pulling tool, the clamping lobes clamp one end of the to-be-turned slender shaft, the other end of the slender shaft is tightly clamped on a three-jaw self-centering chuck of the lathe, the clamping pulling tool is fixed to the lathe tailstock, the lathe tailstock drives the clamping lobes to move backwards, the slender shaft is always in a tensioned state, and the pressing force of the slender shaft during regular turning processing is changed to tensioning force, so that the purpose that the slender shaft does not bend during the processing process is guaranteed.
Description
Technical field
The present invention relates to the card pull tool of turning slender axles on a kind of lathe, belong to clamp art.
Background technology
At present, when slender axles processed by lathe, due to workpiece poor rigidity, easily produce because of cutting force and the effect of gravity
Give birth to flexural deformation or vibrate, reducing crudy；Simultaneously because radiating condition is poor, under heat in metal cutting effect, workpiece produces
Raw bigger line expands, and adds that the most top effect produces flexural deformation；Further, since Workpiece length is long, once
Feed distance is the longest, and tool wear is relatively big, increases the form error of workpiece further, greatly have impact on adding of slender axles
Working medium amount.
Summary of the invention
The technical problem to be solved is: overcome the deficiencies in the prior art, it is provided that turning slender axles on a kind of lathe
Card pull tool, to solve slender axles in the technical problem adding flexible deformation in man-hour.
In order to solve above-mentioned technical problem, the technical scheme is that, the card pull tool of turning slender axles on a kind of lathe,
Including:
For the overcoat being arranged on tail stock, overcoat is fixed by screws on tail stock sleeve；
Mandrel, one end of mandrel is arranged on tail stock by bearing the thrust ball bearing of axial load, and the other end has
Have for supporting the top of slender axles；
Card lobe, described card lobe is two semicircle sets for clamping slender axles, is cased with a clamping set outside card lobe, in order to card
Tight set push card lobe tension slender axles, described clamping set and mandrel pass through thread connection.
Further for bearing core shaft reduce friction, described mandrel is arranged on tail stock also by deep groove ball bearing.
Further, described deep groove ball bearing is provided with two, and is provided with spacer between this two deep groove ball bearing.
After have employed technique scheme, the one end treating the slender axles of turning is blocked by the card lobe of the present invention, slender axles another
One end is stuck on the three-jaw self-centering chuck of lathe and clamps, and the present invention is fixed on tail stock, tail stock band
Dynamic card lobe is moved rearwards by, and makes slender axles remain tension, thrust to slender axles when changing conventional turnery processing
For tightening force, thus ensure that slender axles not bent in process, it is ensured that processing is smoothed out；The mandrel of the present invention is passed through
One thrust ball bearing that can bear axial load is arranged on tail stock, is passed through thrust ball bearing by the pulling force of tail stock
It is delivered to mandrel, and acts on slender axles, so that slender axles bear axial tension while rotating, improve elongated
The axle stability when machining, decreases workpiece deformation, and the crudy of slender axles significantly improves；The present invention is special
It is suitable for the turning of minor diameter slender axles.
Accompanying drawing explanation
Fig. 1 is the partial sectional view of the present invention；
In figure, 1, overcoat, 2, screw, 3, spacer, 4, deep groove ball bearing, 5, thrust ball bearing, 6, mandrel,
7, clamping set, 8, card lobe, 9, slender axles, 10, tail stock, 11, three-jaw self-centering chuck.
Detailed description of the invention
It is clearly understood to make present disclosure be easier to, below according to specific embodiment and combine accompanying drawing, to this
Invention is described in further detail.
As it is shown in figure 1, the card pull tool of turning slender axles on a kind of lathe, including:
For the overcoat 1 being arranged on tail stock, overcoat 1 is fixed on tail stock sleeve by screw 2；
Mandrel 6, one end of mandrel 6 is arranged on tail stock 10 by bearing the thrust ball bearing 5 of axial load,
The other end has for supporting the top of slender axles 9；
Card lobe 8, described card lobe 8 is two semicircle sets for clamping slender axles 9, is cased with a clamping set outside card lobe 8
7, in order to clamping is overlapped 7 push card lobes 8 and strained slender axles 9, and described clamping set 7 passes through thread connection with mandrel 6.
Alternatively, as it is shown in figure 1, the friction for bearing core shaft and when reducing central axis, mandrel 6 is also by zanjon
Ball bearing 4 is arranged on tail stock 10.
Preferably, as it is shown in figure 1, deep groove ball bearing 4 is provided with two, and it is provided with between this two deep groove ball bearing 4
Spacer 3.
When utilizing turning slender axles of the present invention, take reverse feed i.e. by the head of a bed to the mode of tailstock direction feed.
Before processing, first at one end car one groove of slender axles 9, card lobe 8 is stuck in above-mentioned groove, and overlaps 7 with clamping
Push card lobe 8 strains slender axles 9；On the other hand, the conical sliding support of mandrel 6 left end on the centre bore of slender axles 9,
Slender axles 9 position under the effect of mandrel 6 at card lobe 8, clamping set 7 by the way of folder one top.
The present invention being arranged on tail stock, the other end three-jaw self-centering chuck 11 of slender axles 9 clamps, and makes
Tail stock pulls back；Go out, near one end car of three-jaw self-centering chuck 11, a section coordinated with follow-rest at slender axles 9
Outside cylinder, its diameter and the mutual phase grinding of shelf pawl of follow-rest, make Cylindrical Surfaces Contact good；During turning, divide rough turn, smart
Car two procedures.
During whole turnery processing, at any time the Ben Kala instrument on tail stock is moved rearwards by, makes slender axles 9 begin
Keep tension eventually, thus ensure that processing is smoothed out.
The one end treating the slender axles 9 of turning is blocked by the card lobe 8 of the present invention, and the other end of slender axles 9 is stuck in the three of lathe
On jaw self-centering chuck 11 and clamp, and the present invention being fixed on tail stock 10, tail stock 10 drives card lobe 8
Being moved rearwards by, make slender axles 9 remain tension, when changing conventional turnery processing, the thrust to slender axles 9 is
Tightening force, thus ensure that slender axles 9 not bent in process, it is ensured that processing is smoothed out；The mandrel 6 of the present invention is led to
Cross a thrust ball bearing 5 that can bear axial load to be arranged on tail stock 10, by the pulling force of tail stock through thrust
Ball bearing 5 is delivered to mandrel 6, and acts on slender axles 9, so that slender axles 9 bear axially while rotating
Pulling force, improves the slender axles 9 stability when machining, decreases workpiece deformation, the crudy of slender axles 9
Significantly improve；Present invention is especially suitable for the turning of minor diameter slender axles.
Particular embodiments described above, to present invention solves the technical problem that, technical scheme and beneficial effect entered
One step describes in detail, be it should be understood that the specific embodiment that the foregoing is only the present invention, is not limited to
