Abstract
The utility model discloses a vehicle long-axle clamp which comprises a Morse taper clamp body; one end of the middle part of the Morse taper clamp body is a screw hole, and the other end in the middle of the Morse taper clamp body is a light hole; the screw hole is connected with a pressure adjusting screwed plug; the light hole is connected with a tip; a spring is arranged between the tip and the pressure adjusting screwed plug; the tip is sleeved by the spring; and one end of the Morse taper clamp body is also connected with a shifting fork. The vehicle long-axle clamp has the beneficial effects that when the vehicle long-axle clamp works, an axle is installed between the tip and a machine tool permanent seat and is fixed by the shifting fork; after the axle is adjusted, the machine tool permanent seat is immovable; in the processing process, cutting heat is contentiously generated, so that and the temperature of the axle rises; meanwhile, according to the properties of thermal expansion and cold contraction of materials, the axle is lengthened; and as the machine tool permanent seat can not axially move, the tip at the end of a machine tool head compresses the spring to move backwards through the axle, so that the thermal deformation energy of the axle is released, and the bending deformation is avoided, thereby improving the processing precision of the axis.
Description
Technical field
The utility model relates to the part processing field, is specifically related to a kind of vehicle commander's axle clamp tool.
Background technology
Run into processing major axis part on lathe through regular meeting aborning, because the major axis work in-process is because the effect of heat in metal cutting makes an expanded by heating elongation.In order to guarantee machining accuracy, in the processing of axle, all be to adopt two ends to head on processing, and toply all fix with top, can not move axially along with the receiving thermal stretching of axle, thereby axle is deformed, the machining accuracy of influence spool.
Now generally take in the process of axle, utilize manually tailstock centre to be become flexible to hold out against again again,, reduce the influence of a distortion of temperature distortion generation machining accuracy to reduce causing the bending of axle owing to the thermal stretching that receives of axle.But this measure can only be carried out after each feed finishes, and can not in process, carry out, and the axle temperature distortion is at any time, all taking place all the time in the process, thus adopt the influence that manually can only reduce to be out of shape, and can not thoroughly solve.
Summary of the invention
The technical problem that the utility model will solve provides a kind of vehicle commander's axle clamp tool, solves when processing major axis on the lathe shaft distortion that heat in metal cutting causes; Influence machining accuracy; The thermal deformation that the heating of axle causes is eliminated at any time, improved the machining accuracy of axle, guarantee crudy.
For achieving the above object, the technical scheme of the utility model is following:
A kind of vehicle commander's axle clamp tool comprises the Morse's taper clamp body, and said Morse's taper clamp body middle part one end is a screw; The other end is a unthreaded hole; Said screw is connected with pressure adjustment plug, and unthreaded hole is connected with top, and said top the adjustment between the plug with pressure is provided with spring.
Said spring housing be contained in top on.
One end of said Morse's taper clamp body also is connected with shift fork.
Through technique scheme, the beneficial effect of the utility model is:
Solved major axis work in-process heat in metal cutting and caused that length increases, made axle produce flexural deformation, reduced the difficult problem of machining accuracy, the thermal deformation energy that the major axis work in-process is produced discharges timely, has avoided the bending of axle, has improved crudy.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing in describing below only is some embodiment of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of the utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
With reference to Fig. 1, a kind of vehicle commander's axle clamp tool comprises Morse's taper clamp body 1; Said Morse's taper clamp body 1 middle part one end is a screw, and the other end is a unthreaded hole, and said screw is connected with pressure adjustment plug 2; Unthreaded hole be connected with top 3, said top 3 and pressure adjustment plug 2 between be provided with spring 4.
Said spring 4 is sleeved on top 3.
One end of said Morse's taper clamp body 1 also is connected with shift fork 5.
Morse's taper clamp body and lathe spindle hole are connected, and front end has screw thread, and screw thread and shift fork are connected.An end is a screw in the middle of the Morse's taper clamp body, and the other end is a unthreaded hole, and screw cooperates unthreaded hole and top cooperation with pressure adjustment plug.
Operation principle: top front end becomes little matched in clearance with unthreaded hole on the Morse's taper clamp body, spring housing be contained in top on, pressure adjustment plug one end is a square, it is convenient to be that tool using rotates, pressure adjustment plug can be adjusted the size of spring to top pressure.
During work, axle be installed in top and tailstock tool between, after adjusting, tailstock tool fixed (axially), top through dial, drive axle and go up a shift fork of installing and rotate, a cut that realizes spool.Work in-process, heat in metal cutting constantly produces, and axle temperature also increases, and according to the expansion and contraction property of material, shaft length increases simultaneously.Because tailstock tool can not move axially, axle just makes the top compression spring of head end move backward, thereby discharges the thermal deformation energy of axle, avoids producing flexural deformation, thereby improves the machining accuracy of axle.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
