Abstract

A fixture for an adjustable fixed ball valve belongs to the technical field of valve processing technical equipment. The fixture is as follows: a shaft core is fixed at a triangular tray and the end portions of the shaft core extend out of the triangular tray; a sliding bearing is firstly sleeved into a groove of a lower positioning plate and then is fixed in the shaft core; a valve body is sleeved to an upper positioning plate after being fixed on the lower positioning plate; and threads formed on the end portions of the shaft core are connected with nuts to generate axial pretightening force for fastening. Compared with the existing valve processing technical equipment technology, the fixture for the adjustable fixed ball valve has the advantages that when one end of the valve body is completely processed, the valve body does not need to be demounted and just needs to be rotated by 180 degrees, and when a middle head at one end is completely processed, the valve body can be easily rotated when the direction is changed to process the other end; and the following problems in the background technology that after the processing of one end, the valve body needs to be demounted for changing the direction, thus increasing the deviation between the coaxiality of the upper middle head and that of the lower middle head after processing, the deviation needs to be corrected by a lathe worker through own experience and the processing efficiency of the worker is affected are solved.

Description

A kind of adjustment type fixing ball valve frock
Technical field
The invention belongs to valve processing technology equipment technology field, particularly a kind of adjustment type fixing ball valve frock.
Background technology
The limitation that existing engine lathe three-jaw, four paws are processed fixing ball valve, boring machine are not suitable for again the processing bore less than the fixing ball valve below the DN100.The frock that head uses in the processing fixing ball valve at present has certain limitation, must the lower valve body of dismounting after must an end processing, adjust to the other end that needs processing, retighten on frock, just can process behind the correction center, often calibrating this procedure can be cumbersome time-consuming again, need by means of the axiality after the upper and lower middle head processing of workman's experience guarantee valve body, in case it is improper to proofread and correct, the upper and lower valve rod of bad assurance is with the axiality of spool and valve body head, cause the decline of workman's working (machining) efficiency, also cause assembling ball valve process slowly.
Summary of the invention
The present invention provides a kind of the upper and lower middle head of fixing ball valve has been shaped up and down axiality of rear easy assurance in order to solve the deficiencies in the prior art, improves a kind of adjustment type fixing ball valve frock of working (machining) efficiency.
The technical scheme that the present invention solves its problem employing is: a kind of adjustment type fixing ball valve frock, comprise that the axle core is fixed in triangular plate, triangular plate is stretched out in its end, sliding bearing is inserted in first lower positioning disk groove, be fixed in again among the axle core, after valve body is fixed in lower positioning disk, be inserted in again positioning disk, connect the generation axial pre tightening force by axle core end thread with nut and carry out fastening.
Compare in existing equipment Technology, the invention has the advantages that: after an end valve body machines, need not pull down valve body, as long as valve body Rotate 180 degree is just passable, and after head in the end machines, it is not hard when valve body is rotated in transposing direction processing other end, and be easy to guarantee on the processing rear valve body, axiality and the precision of lower head, having solved needs to pull down valve body transposing direction after the end processing in the background technology, can make like this, the deviation of axiality strengthens after the lower head processing, need turner by rule of thumb it to be proofreaied and correct, and affect workman's working (machining) efficiency.
Description of drawings

Fig. 2 is the structural representation of prior art
Specific implementation method
As shown in Figure 1, a kind of adjustment type fixing ball valve of the present invention frock comprises sliding bearing 13, upper positioning disk 6, lower positioning disk 11, triangular plate 9, axle core 1; Axle core 1 passes triangular plate 9 (A to) centre bore and is connected and fixed by nut 16, be provided with adjustment pad 15 in axle core 1 boss upper end, the bottom is provided with lower adjustment pad 14, sliding bearing 13 is inserted in lower positioning disk 6, be connected with axle core 1 again, between triangular plate 9 and the lower positioning disk 63 road grooves are set, plane needle bearing assembly 20 is fixed in the 3 road grooves, to prevent that the plane needle bearing from producing radial-play, there is plane needle bearing 2 lower positioning disk 6 upper ends, plain cushion 3, top nut 4, lower nut 5, top nut 4 plays a part fastening, lower nut 5 plays a part locking, lower positioning disk 6 and triangular plate 9 two ends are respectively equipped with counterbore and through hole, fixed by socket cap hexagon socket head cap screw 7 and nut 8, put into again positioning disk 6, upper positioning disk 6, the fixing valve body 30 that needs processing between the lower positioning disk 11, positioning disk 6 is connected and fixed with axle core 1 end thread by nut 12 on it, and triangular plate 9 (B to) then is fixed on the lathe by four paws 10.
From the above, the plane needle bearing assembly 20 that the present invention arranges between upper positioning disk 6 and lower positioning disk 11, the plane needle bearing 2 that arranges in lower positioning disk 11 upper ends is in order to reduce valve body 30 frictional resistance when rotated, valve body 30 to be rotated lighter.
From the above, the present invention is provided with in axle core 1 boss upper end and adjusts pad 15, and the bottom is provided with lower adjustment pad 14, and the frictional force when effect is to reduce 1 rotation of axle core also plays a part to adjust axial.
From the above, the present invention is respectively equipped with counterbore and through hole at lower positioning disk 6 and triangular plate 9 two ends, is fixed by socket cap hexagon socket head cap screw 7 and nut 8, plays a part fastening after valve body 30 adjustment are complete and the lower positioning disk 13 in location.
As shown in Figure 1, axle core 1 left part is provided with opposite side 40, can rotate by be connected to prevent axle core 1 with handle when nut 16 is connected degree of tightness with nut, just can not be with moving axis core 1 to rotate together when nut 10 is rotated.
