Description
Technical field
The present invention relates to the clamping of a kind of workpiece or cutter, supporting, positioner, is specifically related to a kind of ball valve core clamping device.
Background technology
In China, ball valve is widely used in industries such as petroleum refining, long-distance transport pipes, chemical industry, papermaking, pharmacy, water conservancy, electric power, municipal administration, iron and steel, occupies very important status in national economy.It has the action of half-twist, and spool is spheroid, has manhole or passage by its axis.Ball valve is mainly used to make the flow direction cutting off, distribute and change medium in pipeline, and it is tight that it only needs to use the operation of half-twist and very little rotating torque just can close.Ball valve optimum makees switch, stop valve uses.
Ball valve mainly relies on the cooperation of spool and valve seat to open and close valve, spool is provided with medium runner, when medium runner connecting pipe, and valve open, when the sphere closed conduct of spool, valve closing, so the required precision of the sphere of spool is very high, during processing spool, usually spool to be fixed, then be fixed on lathe and carry out Surface Machining, the shape due to ball valve is spherical, is not easy to be fixed.
Summary of the invention
For the defect that above-mentioned prior art exists, the object of the present invention is to provide a kind of spool of ball valve can clamping, and the simple ball valve core clamping device of structure.
For achieving the above object, technical scheme of the present invention is as follows:
Ball valve core clamping device, wherein, comprise mounting disc, supporting base and pressure strip, described supporting base is connected with mounting disc, described supporting base hollow, the inner surface of hollow space coordinates with the valve core outer surface of ball valve, described pressure strip can insert in the medium channel of spool, and two ends are stretched out from medium channel, described pressure strip two ends are provided with hold-down apertures, the described mounting disc position relative with hold-down apertures is provided with screwed hole, is equipped with screw rod, and is compressed by nut in the screwed hole at described pressure strip two ends and hold-down apertures.
When adopting technique scheme, first spool is placed on supporting base, make medium channel along two screwed hole line directions, and be in level, now, the inner surface of spool is supported on the inner surface of hollow space, then pressure strip is inserted in medium channel, use two bolts to insert the hold-down apertures at pressure strip two ends respectively subsequently, and be threaded with the screwed hole in mounting disc, screw rod upper end nut compresses, and the spool of ball valve just can be fixed by such pressure strip.The present invention adopts supporting base to coordinate and supports spool, is clamped by spool by pressure strip and bolt, and structure is very simple, but can be clamped by ball valve core preferably.
Further, described hold-down apertures is bar hole, and this bar hole is arranged along pressure strip length direction.So just need not require that the hold-down apertures at pressure strip two ends accurately aligns with corresponding screwed hole respectively, required precision is lower, reduces difficulty of processing.
Further, the surface of described pressure strip pressed spool is the arc surface coordinated with the inner surface of medium channel.Spool is supported by supporting base, pressure strip is had to compress, pressure strip can apply pressure to the surface of spool medium channel, if the surface of pressure strip pressed spool is the arc surface coordinated with the inner surface of medium channel, then pressure strip and spool contact surface larger, the situation of local pressure can be avoided, can prevent spool from damaging.
Further, described mounting disc is provided with the through hole of connected component bearing hollow space.The waste material that dust or processing produce can fall in supporting base, and the through hole being provided with connected component bearing hollow space can be then that dust or waste material drop out in time.If clean the inner surface of supporting base hollow space in addition, without the need to moving whole clamping device, directly can clear up away from through hole.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Structural representation when Fig. 1 is ball valve core clamping device embodiment of the present invention clamping spool;
Fig. 2 is the structural representation of ball valve core clamping device embodiment of the present invention when not clamping spool;
Fig. 3 is the structural representation of mounting disc and rest portion in ball valve core clamping device embodiment of the present invention.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: mounting disc 1, screwed hole 11, through hole 12, supporting base 2, inner surface 21, pressure strip 3, bar hole 31, spool 4.
As depicted in figs. 1 and 2, a kind of ball valve core clamping device, wherein, comprise mounting disc 1, supporting base 2 and pressure strip 3, supporting base 2 is connected with mounting disc 1, supporting base 2 hollow, as Fig. 3, the inner surface 21 of hollow space coordinates with spool 4 outer surface of ball valve, and pressure strip 3 can insert in the medium channel of spool 4, and two ends are stretched out from medium channel, pressure strip 3 two ends are provided with hold-down apertures, mounting disc 1 position relative with hold-down apertures is provided with screwed hole 11, is equipped with screw rod, and is compressed by nut in the screwed hole 11 at pressure strip 3 two ends and hold-down apertures.
Hold-down apertures is bar hole 31, and this bar hole 31 is arranged along pressure strip 3 length direction.So just need not require that the hold-down apertures at pressure strip 3 two ends accurately aligns with corresponding screwed hole 11 respectively, required precision is lower, reduces difficulty of processing.
The surface of pressure strip 3 pressed spool 4 is the arc surface coordinated with the inner surface 21 of medium channel.Spool 4 is supported by supporting base 2, pressure strip 3 is had to compress, pressure strip 3 can apply pressure to the surface of spool 4 medium channel, if the surface of pressure strip 3 pressed spool 4 is the arc surface coordinated with the inner surface 21 of medium channel, then pressure strip 3 is larger with spool 4 contact surface, the situation of local pressure can be avoided, can prevent spool 4 from damaging.
As Fig. 3, mounting disc 1 is provided with the through hole 12 of connected component bearing 2 hollow space.The waste material that dust or processing produce can fall in supporting base 2, and the through hole 12 being provided with connected component bearing 2 hollow space can be then that dust or waste material drop out in time.If clean the inner surface 21 of supporting base 2 hollow space in addition, without the need to moving whole clamping device, directly can clear up away from through hole 12.
Concrete using method:
As Fig. 1 and 2, first spool 4 is placed on supporting base 2, make medium channel along two screwed hole 11 line directions, and be in level, now, the inner surface 21 of spool 4 is supported on the inner surface 21 of hollow space, then pressure strip 3 is inserted in medium channel, use two bolts to insert screwed hole 11 and the hold-down apertures at pressure strip 3 two ends respectively subsequently, and compress with nut, the spool 4 of ball valve just can be fixed by such pressure strip 3.
