Abstract
The invention relates to a slender shaft clamping puller. The slender shaft clamping puller comprises a connection shaft, an end cover, a base body and a sliding sleeve, wherein the sliding sleeve is arranged in the base body; a conical hole is formed in the sliding sleeve; the connection shaft is arranged in the conical hole of the sliding sleeve; one end of the connection shaft is fixed to one end of the sliding sleeve through a nut; the other end of the connection shaft is arranged outside the base body; a conical damping sleeve corresponding to the conical hole is arranged between the sliding sleeve and the connection shaft; an adjusting ring is arranged at the large-diameter end of the damping sleeve; one end of the base body is sleeved with the end cover in a threaded connection mode; the end cover and the sliding sleeve are connected through a spring; a through hole for containing the connection shaft is formed in the center of the end cover. The slender shaft clamping puller has the advantages of improving production efficiency and benefits, reducing vibration, preventing a slender shaft from bending and deforming, achieving reverse feeding and the like.
Description
Technical field
The present invention relates to mechanical frock technical field, particularly a kind of slender axles clamping pull head.
Background technology
When slender axles got on the bus by engine lathe, if forward feed, clamping with three-jaw chuck slender axles, then act on axial tangential force on slender axles to slender axles being a biased axial compressive force.Under the effect of bias pressure, slender axles very easily bend and vibration, affect turnery processing and machining accuracy.In production practices, available reverse feed car slender axles, level car moves towards tail stock to from chuck, if at this moment hold out against slender axles with tailstock centre, then between lathe tool and tailstock centre, slender axles are still by bias pressure, slender axles still can flexural deformation, causes the possibility that workpiece is scrapped, have a strong impact on production efficiency and benefit.
Summary of the invention
For the problems referred to above, the object of this invention is to provide one and enhance productivity and benefit, reduce vibration, prevent slender axles flexural deformation, can the slender axles clamping pull head of reverse feed.
Realize technical scheme of the present invention as follows:
A kind of slender axles clamping pull head, comprise connecting axle, end cap, matrix and slip cap, described slip cap is arranged in matrix, slip cap is provided with bellmouth, connecting axle is arranged in the bellmouth of slip cap, one end of connecting axle is fixed on one end of slip cap by nut, the other end of connecting axle is placed in outside matrix, the taper damping sleeve adapted to taper Kongxiang is also provided with between slip cap and connecting axle, the one end being positioned at damping sleeve diameter larger is also provided with adjustment ring, end cap is threaded connection the one end being sheathed on matrix, be connected by spring between end cap with slip cap, end cap central is provided with the through hole of accommodating connecting axle.
The other end of described matrix is provided with the taper shank be connected with tail stock, and matrix surface is provided with the locking nut for clamping slip cap, and advantage is generally when straining connecting axle, locking nut screwing can be locked slip cap, be located, prevent it from sliding, contribute to processing work.
Be threaded connection between described adjustment ring and slip cap, advantage adjustment ring and slip cap can form an airtight cavity, for placing and compressing damping sleeve.
The other end of described connecting axle is provided with the screwed hole for connecting workpiece.
Have employed above-mentioned scheme, connecting axle is fixedly connected with by nut with slip cap, can be that connecting axle seesaws together with slip cap like this, end cap plays guide effect, by rotating end cap, spring change can extrude slip cap, is that slip cap moves, and effect reaches the effect of axial tightening connecting axle, with that can oppositely feed turning; Arranging of damping can eliminate the vibrations produced in process on the one hand, prevent from workpiece processes ripple, can be set to pyramidal structure with slip cap and be connected by damping sleeve on the other hand, can prevent the inner conical surface of damping sleeve and slip cap from producing interlocking phenomenon, and then prevent damping sleeve locking workpiece and vexed car phenomenon occurs; By regulating the axial location of adjustment ring, damping sleeve and the gap between slip cap and connecting axle can be adjusted, flexible structure, simple to operate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In accompanying drawing, 1 is connecting axle, and 2 is matrix, and 3 is slip cap, and 4 is damping sleeve, and 5 is adjustment ring, and 6 is nut, and 7 is end cap, and 8 is spring, and 9 is screwed hole, and 10 is taper shank, and 11 is locking nut.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
As Fig. 1, a kind of slender axles clamping pull head, comprise connecting axle 1, end cap 7, matrix 2 and slip cap 3, described slip cap 3 is arranged in matrix 2, slip cap 3 is provided with bellmouth, connecting axle 1 is arranged in the bellmouth of slip cap 3, one end of connecting axle 1 is fixed on one end of slip cap 3 by nut 6, the other end of connecting axle 1 is placed in outside matrix 2, the taper damping sleeve 4 adapted with bellmouth is also provided with between slip cap 3 and connecting axle 1, the one end being positioned at damping sleeve 4 diameter larger is also provided with adjustment ring 5, end cap 7 is threaded connection the one end being sheathed on matrix 2, be connected by spring 8 between end cap 7 with slip cap 3, end cap 7 center is provided with the through hole of accommodating connecting axle 1.
The other end of described matrix 2 is provided with the taper shank 10 be connected with tail stock, and matrix 2 is provided with the locking nut 11 for clamping slip cap 3 on the surface, and advantage is generally when straining connecting axle, locking nut screwing can be locked slip cap, be located, prevent it from sliding, contribute to processing work.
Be threaded connection between described adjustment ring 5 and slip cap 3, advantage adjustment ring and slip cap can form an airtight cavity, for placing and compressing damping sleeve.
The other end of described connecting axle 1 is provided with the screwed hole 9 for connecting workpiece, in turning, axial tension can be imposed to workpiece all the time for making clamping pull head and have good centering simultaneously, adopt between workpiece with connecting axle and be threaded, so, answer preprocessing to go out a bit of screw thread and taper seat in one end of workpiece.After folder pulls a cart to cut, then screw thread and taper seat part car are gone.
After matrix is fixed on tail stock, slip cap, adjustment ring, damping ring and connecting axle can axially move in matrix, before turning, first workpiece is tightened on centering location in connecting axle, then rotates the end cap be threaded with matrix, pressing spring, thus promote the slip of slip cap phase tailstock direction, realize the axial tightening to workpiece, then carrying out radial location by locking nut to slip cap, then elder sister can reflect on oneself feed turning.
