Abstract
The utility model provides a valve body which can meet coaxiality requirements of valve body type workpieces, and the valve body is used for overcoming the defects in the prior art that when the valve body type workpieces are machined, clamping and positioning are inconvenient so that the valve body type workpieces cannot meet the coaxiality requirements. The valve body comprises a first circulation end 3, a second circulation end 4 and a positioning end opposite to the first circulation end 3; a positioning hole is arranged on the outer surface of the positioning end; and the positioning hole and the first circulation end are coaxial. By adopting the valve body with the structure, the positioning end opposite to the first circulation end is provided with a molded surface of the positioning hole; and the positioning hole and the first circulation end are coaxially arranged so that the positioning is convenient and accurate and the coaxiality requirements of the first circulation end can be met.
Description
Technical field
The utility model relates to a kind of valve body.
Background technique
In prior art, when the valve body of processing special profile as shown in Figure 1, because the spacing between the outer surface of the second go side 24 of the profile 22 of valve body and valve body is little, so can't clamp with three jaw chuck, and when adopting the four jaw chuck clamping, because the external dimension conformity of valve body blank is bad, need frequent clamping position and the clamping dynamics adjusted, when causing this kind valve body of production, manufacturing efficiency is low.Simultaneously, during clamping, clamped the outer surface of valve body class workpiece blank by four jaw chuck, the external dimension conformity of valve body blank is bad, institute so that locate inaccurate,, be difficult to satisfy the coaxality requirement of valve body class workpiece.
The model utility content
The purpose of this utility model is that during for prior art processing valve body class workpiece, the clamping location is inconvenient, to making valve body class workpiece can not satisfy the deficiency that coaxality requires, provides a kind of and can satisfy the valve body that valve body class workpiece coaxality requires.
The purpose of this utility model is achieved through the following technical solutions:
A kind of valve body comprises first-class go side 3, second go side 4 and the positioning end relative with described first-class go side 3, is provided with positioning hole at the outer surface of described positioning end, and described positioning hole is coaxial with described first-class go side;
Described outer surface at described positioning end is provided with profile;
Described profile is inclined-plane or curved surface
Described positioning hole is blind hole.
Adopt the valve body of the utility model structure, owing to being provided with the profile of positioning hole at the positioning end relative with first-class go side, this positioning hole and first-class go side axis arrange, so the location is convenient, accurate, can fully satisfy the coaxality requirement of first-class go side.

Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is made explanation further:
As shown in Figure 2, valve body of the present utility model comprises first-class go side 23 and second go side 24 at least, an end relative with first-class go side 23 is positioning end, the outer surface of this positioning end is provided with profile 22, profile 22 is inclined-plane or curved surface, at positioning end, positioning hole 21 is set, positioning hole 21 is coaxial with the circulation end.Positioning hole 21 is preferably blind hole.
When processing circulation end, coordinate with positioning hole with the positioning boss on clamping device, with the pressure head compression profile 22 of clamping device, process.
Preferably install clamp device as shown in Figure 3, it comprises pressing plate 2, connecting plate 3, connecting sleeve 6, pull bar 7 and housing 10.This housing 10 comprises a housing bottom 12, is provided with positioning boss 11 in the outer end of housing bottom 12, and pressing plate 2 is L-type, and the one end is the pressure head 14 of pushing down valve body 1, and the other end is connecting end; Be provided with at housing bottom 12 through hole that supply plate 2 passes, the pressure head 14 of pressing plate is arranged on the outside of housing 10, and the connecting end of pressing plate is arranged on the inside of housing 10, is fixedly connected with connecting plate 3.Be provided with through hole on connecting plate 3, pass for pull bar 7; Be provided with pillow block rank 13 on pull bar 7, pillow block rank 13 are arranged on a side that is positioned at housing bottom of connecting plate; Connecting sleeve 6 is sleeved on pull bar 7, and is fixedly connected with housing 10.The coaxial setting of excircle of pull bar 7, positioning boss 11 and connecting sleeve 6; Be provided with the connecting thread that is connected with machine tool chief axis 8 on connecting sleeve 6, be provided with Compress Spring 5 between connecting sleeve and connecting plate, this Compress Spring is sleeved on pull bar.
Pressing plate is at least two and distribution symmetrically.
At the positioning hole 21 that an end setting relative with the processing end of valve body and positioning boss 11 are complementary, this positioning hole 21 arranges the screw thread that the connecting thread with connecting sleeve is complementary on the main shaft of lathe.
During use, connecting sleeve is connected with machine tool chief axis, at this moment, machine tool chief axis, connecting sleeve and positioning boss should coaxial settings.
Valve body is sleeved on positioning boss 11 by positioning hole, pressure head is pressed on the location profile 15 of valve body blank outer surface setting, pull pull bar 7, make pressure head 14 compress location profile 15, thereby valve body blank is clamped, carry out clamping and locate.
Can pull pull bar by cylinder, also can pull pull bar by manual or alternate manner, Compress Spring makes pressing plate compress valve body 1, then pull bar is carried out locking and positioning.
When unloading valve body, pull bar 7 is unclamped, unclamp valve body at the effect press table 2 of Compress Spring tension force.
Convenient for connecting plate and pressing plate are installed, be provided with handle hole at the corresponding site of housing, operate for the operator.
In order to locate more accurately and reliably, the internal surface of pressure head is inclined-plane or curved surface, is complementary with the profile at the clamping position of valve body.
