Abstract
The utility model discloses a machining device for a ball valve element. The machining device for the ball valve element is characterized by comprising a main shaft, a loading and unloading nut, an expansion sleeve, a press plate and a fixing bolt, wherein the loading and unloading nut is arranged in the middle of the main shaft in a sleeved mode, one end of the main shaft is a clamping end, the other end of the main shaft is a circular truncated cone shape machining end, the machining end is sleeved with the adaptive expansion sleeve, the fixing bolt penetrates through the press plate and then is fixed on the outer end face of the machining end, and the diameter of the press plate is larger than that of the outer end face of the machining end. The machining device for the ball valve element is simple and reliable in structure, convenient to operate, and capable of meeting the machining and fixing requirements of various specifications of ball valve elements. A central hole large-area fixing method is adopted for the ball valve element, stability and precision are guaranteed, and the production quality and efficiency of the ball valve element can be effectively improved.
Description
Technical field
The utility model relates to a kind of frock clamp, is specifically related to a kind of processing unit (plant) for ball valve core.
Background technology
In the process of manufacture of ball valve core, need to be to quality and the efficiency of the ball valve core ball valve core that fixing rear guarantee processes accurately, 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 also disunities of model aperture, manufacturing enterprise or maintaining unit exigence one at ball valve core can adapt to different product model, simple to operate, fixing processing tool accurately.
Utility model content
The utility model is for the deficiencies in the prior art, proposes a kind of application model various, simple to operate, fixing accurately for the processing unit (plant) of ball valve core.Concrete technical scheme is as follows:
A kind of processing unit (plant) for 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, on this processing end, overcoat 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 utility model 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, load onto pressing plate in processing end outer face, trap the ball in valve core, load and unload nut and set bolt by adjusting, 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 utility model, 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.
The beneficial effects of the utility model are: simple and reliable for structure, easy to operate, the ball valve core that can adapt to Multiple Type is processed fixed demand; Adopt centre bore large area to fix to ball valve core, ensured stability and accuracy, can effectively improve production quality and the efficiency of ball valve core.
Brief description of the drawings
Fig. 1 is the utility model structure cutaway view;
Fig. 2 is right view of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
As depicted in figs. 1 and 2: a kind of processing unit (plant) for 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 that tapering 0.1 is spent, 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, be with dynamic pressure plate 4 to push expansion sleeve 3 by twisting set bolt 5, expansion sleeve 3 is expanded, by stable ball valve core being fixed, 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.
