Abstract
The invention discloses a double-shaft rotating ball body seal grinding tool and method, and relates to the field of ball body grinding. The double-shaft rotating ball body seal grinding tool and method solve the problems that an existing ball body grinding technology can only conduct simple grinding treatment on a ball body, the surface roughness of the ball body is slightly large, the roundness value is low and the valve quality is affected. The double-shaft rotating ball body seal grinding tool comprises a transverse rotating clamp, a longitudinal rotating valve seat and the ball body to be ground. A transverse rotating shaft drives the ball body to be ground to rotate. The concave friction surface of the longitudinal rotating valve seat is in contact with the top face of the ball body to be ground. The grinding method includes the steps of preparing the tool, assembling, opening the transverse rotating clamp and the longitudinal rotating valve seat, and enabling the longitudinal rotating valve seat to make left-right swing movement and all the ball surfaces of the ball body to be ground to be abraded. According to the double-shaft rotating ball body seal grinding tool and method, two rotating shafts are used for abrading the surfaces of the ball body to be ground, the friction position does not need to be changed and adjusted manually and repeatedly, and a large amount of manual work is saved; meanwhile, the friction precision is high, and the ball body roundness and the roughness of the ball body to be ground can meet requirements.
Description
Technical field
The present invention relates to ball lapping field, particularly relate to frock and the method for the grinding of a kind of double-axle rotation ball seal.
Background technology
The sealing property of ball valve, depends on the precision of ball body of valve to a great extent.Simply process is polished because existing ball lapping technique can only realize the spheroid after to turning.Spherome surface roughness after processing is slightly large, and circularities is lower, cannot meet spheroid precision and the roughness requirements of high requirement, affect valve mass; And the abrasion site that needs manually repeatedly convert spheroid could be completely ground whole sphere, and artificial participation is large.
Summary of the invention
For solving the problems of the technologies described above, the invention provides frock and the method for a kind of double-axle rotation ball seal grinding.
The technical solution adopted for the present invention to solve the technical problems is:
A frock for double-axle rotation ball seal grinding, it comprises the horizontal fixture of rotation, rotates vertical valve seat and wait to polish spheroid; The horizontal fixture of described rotation comprises the fixed block rotating transverse axis and be fixed on rotation transverse axis end; Described fixed block be fixed on wait polish spheroid spheroid internal channel in and by rotate transverse axis drive treat polishing spheroid rotate; The end that valve seat is indulged in described rotation is the recessed rubbing surface caved inward as sphere; Described recessed rubbing surface with wait that the end face polishing spheroid contacts; Valve seat is indulged in described rotation can along waiting that the end face polishing spheroid swings.
To swing whole spheres that recessed rubbing surface can be made to touch spheroid by rotating vertical valve seat.
A method for double-axle rotation ball seal grinding, specifically carry out according to the following steps:
One, the frock of double-axle rotation ball seal as claimed in claim 1 grinding is prepared;
Two, will wait that polishing spheroid loads in the frock of above-mentioned double-axle rotation ball seal grinding; Being fixed in the spheroid internal channel waiting to polish spheroid by rotating horizontal fixture, will the recessed rubbing surface of vertical valve seat being rotated and wait the end face close contact polishing spheroid;
Three, open the horizontal fixture of rotation, rotate horizontal fixture and drive spheroid to rotate, meanwhile, open to rotate and indulge valve seat, make rotation indulge valve seat and carry out rotation, the recessed rubbing surface making rotation indulge valve seat acts on the end face waiting to polish spheroid and rubs;
Four, swing recessed rubbing surface is rubbed wait to polish whole spheres of spheroid by rotating vertical valve seat.
The rotating speed of the horizontal fixture of the rotation described in step 3 is 30 ~ 110 revs/min.
The rotating speed that valve seat is indulged in rotation described in step 3 is 30 ~ 110 revs/min.
Advantage of the present invention: the frock of a kind of double-axle rotation ball seal grinding of the present invention and method, the surface of being treated polishing spheroid by two turning cylinders is rubbed, and does not need artificial repeatedly conversion adjustment frictional position, saves a large amount of artificial; Meanwhile, the precision of friction is high, makes to treat that the spheroid circularity of polishing spheroid and roughness satisfy the demands.
