Abstract

The invention discloses a machining tool for valve spools of ball valves. The machining tool is characterized by comprising a spindle, a mounting and demounting nut, a clamping sheath, a pressing plate and a fixing bolt; the mounting and demounting nut is sleeved on the middle portion of the spindle, one end of the spindle is provided with a clamping end, the other end of the spindle is provided with a cone-frustum shaped machining end, the clamping sheath matched with the machining end is sleeved thereon, the fixing bolt penetrates the pressing plate to be fixed on the outer end surface of the machining end, and the diameter of the pressing plate is larger than that of the outer end surface of the machining end. The machining tool is simple and reliable in structure, convenient to operate, and is applicable to fixed machining demands of multiple types of valve spools of the ball valves; the valve spools of the ball valves are fixed in large areas through center holes, stability and precision are guaranteed, and production quality and efficiency of the valve spools of the ball valves can be effectively improved.

Description

A kind of processing tool of ball valve core
Technical field
The present invention relates to a kind of frock clamp, be specifically related to a kind of processing tool of ball valve core.
Background technology
In the process of manufacture of ball valve core, quality and the efficiency of the ball valve core that after need to fixing accurately ball valve core, guarantee processes, but because ball valve core is that spherical while surface is also smooth especially, through hole in the middle of it is also because of different model aperture also disunity, in the manufacturing enterprise of ball valve core or maintaining unit exigence is a kind of can adapt to different product model, simple to operate, fixing processing tool accurately.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose a kind of application model various, simple to operate, fixing accurately.Concrete technical scheme is as follows:
A kind of processing tool of ball valve core, its key is: comprise main shaft, handling nut, expansion sleeve, pressing plate and set bolt, described main shaft middle part cover has handling nut, this main shaft one end bare terminal end, this main shaft other end is truncated cone-shaped processing end, the upper overcoat of this processing end has the expansion sleeve adapting, and described set bolt is fixed on described processing end outer face through after pressing plate, and the diameter of described pressing plate is greater than the diameter of processing end outer face.
The present invention is work like this, unclamp set bolt, take off pressing plate, then expansion sleeve is taken out to processing end, then ball valve core dress is located on processing end, the expansion sleeve that selection and ball valve core centre bore aperture adapt packs processing end into, in processing end outer face, load onto pressing plate, trap the ball in valve core, by adjusting, load and unload nut and set bolt, under the effect of truncated cone-shaped processing end, expansion sleeve is expanded, complete the precise positioning of ball valve core and fixing.
For better realizing the present invention, may further be:
On described expansion sleeve, longitudinally have bar shaped expansion groove, this expansion groove runs through upper surface and the lower surface of expansion sleeve.On expansion sleeve, offer expansion groove, processing technology is simple, expands evenly, and whole expansion sleeve is also more firm.
The tapering of described truncated cone-shaped processing end is 0.1 degree, makes expansion sleeve distending stably, is unlikely to damage ball valve core.
Beneficial effect of the present invention is: simple and reliable for structure, easy to operate, the ball valve core that can adapt to Multiple Type is processed fixed demand; To ball valve core, adopt centre bore large area to fix, guaranteed stability and accuracy, can effectively improve production quality and the efficiency of ball valve core.
Accompanying drawing explanation
Fig. 1 is structure cutaway view of the present invention;
Fig. 2 is right view of the present invention.
The specific embodiment
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
As depicted in figs. 1 and 2: a kind of processing tool of ball valve core, its key is: comprise main shaft 1, handling nut 2, expansion sleeve 3, pressing plate 4 and set bolt 5, described main shaft 1 middle part cover has handling nut 2, this main shaft 1 one end is bare terminal end, this bare terminal end can be clamped in lathe, on drilling machine etc., process, described main shaft 1 other end is the truncated cone-shaped processing end of tapering 0.1 degree, the ball valve core of needs processing is packed on processing end, then on this processing end, be inserted in the conical expansion cover 3 adapting, on this expansion sleeve 3, longitudinally have bar shaped expansion groove, this expansion groove runs through upper surface and the lower surface of expansion sleeve 3, next adopt set bolt 5 to be fixed on described processing end outer face through after circular pressing plate 4, the diameter of this pressing plate 4 is greater than the diameter of processing end outer face, by twisting set bolt 5 band dynamic pressure plate 4 extruding expansion sleeves 3, expansion sleeve 3 is expanded, by stable being fixed of ball valve core, handling nut 2 ball valve core and expansion sleeve 3 are carried out spacing in, can prevent that expansion sleeve 3 excessive expansions from damaging ball valve cores.
