Abstract
The utility model discloses a valve ball grinding head, which comprises a frame body arranged at a machine tool cutter frame, a drive mechanism arranged in the frame body, and a valve ball grinding machine with grinding head components; the valve ball grinding machine with grinding head components is connected with the rotating shaft of the drive mechanism; after a ball is grinded, the surface roughness degree of the ball can reach *-*, and the circular degree t value can reach 0.006 mm.
Description
The utility model provides a kind of ball body of valve honing head, and it includes the support body that is arranged on the lathe cutter saddle, is arranged at the transmission mechanism in the support body, and the part of the grinding head that is connected with the turning cylinder of transmission mechanism, belongs to grinding tool.
The sealing property of ball valve depends on the ball body of valve precision to a great extent.Because existing honing utensil can only be realized the spheroid after the turning is polished processing simply.Spherome surface roughness after the processing is big slightly, and circularities is lower, directly influences valve mass.
The purpose of this utility model promptly provides and a kind ofly can significantly improve the spherome surface roughness, improves the ball body of valve honing head of circularities.
The utility model takes following technical measures to realize its purpose:
The bistrique of honing spheroid is bowl-shape oilstone bistrique, and the slip joint that has thrust piece is set in its rotating shaft, and the other end of this rotating shaft is connected by the turning cylinder of spherical linkage-knee joint shaft coupling and transmission mechanism.
In the present technique measure, the slip joint that has thrust piece can be realized bistrique and treat that the contouring flexibility contacts that the knee joint shaft coupling then can be adjusted bistrique axle center and spheroid shaft core position deviation automatically.Time rotational under the drive of spheroid at machine tool chief axis forms the intricately grinding motion between bowl-shape oilstone bistrique and the spheroid.Cross one another rotation finally makes spherome surface form overlapping curve (polishing scratch), and spherome surface roughness and circularity all obtain tangible raising.
Use this ball body of valve honing machine, can obtain technique effect significantly.The spherome surface roughness can reach after the honing
, circularities 0.006mm.
Accompanying drawing 1 is the structural representation of ball body of valve honing head, and accompanying drawing 2 is bowl-shape oilstone bistrique size calculating sketches.Below in conjunction with accompanying drawing, further narrate technical characterictic by most preferred embodiment.
The ball body of valve honing head, by support body (6), be arranged at the transmission mechanism (8) of support body (6), and the part of the grinding head that is connected with the turning cylinder (7) of transmission mechanism is formed.Its bistrique is a bowl-shape oilstone bistrique (1), the slip joint (2) that has thrust piece (3) is set in the rotating shaft of bistrique (4), and the other end of rotating shaft (4) is hinged by the turning cylinder (7) of spherical linkage (5)-knee joint shaft coupling and transmission mechanism (8).
The design size of bowl-shape oilstone bistrique (1), mainly the size according to ball body of valve size and latus rectum size determines.As shown in Figure 2, ball valve sphere diameter R, latus rectum D, the high H of round platform is the full-size φ of bowl-shape oilstone bistrique.
The ball body of valve honing head is installed on the lathe saddle position, and expander is contained in the access opening of spheroid, spheroid rotation under machine tool chief axis drives.
In the present embodiment, the thrust piece (3) in the slip joint (2) is the compression spring, and bowl-shape oilstone bistrique rotating speed is that per minute 400 changes.Spheroid circularity reaches in the 0.01mm after the honing, roughness
Claims (2)
1, a kind of ball body of valve honing head, it includes the support body that is arranged on the lathe cutter saddle, is arranged at the transmission mechanism in the support body, and the part of the grinding head that is connected with the turning cylinder of transmission mechanism, the bistrique that it is characterized by the honing spheroid is bowl-shape oilstone bistrique, the slip joint that has thrust piece is set in its rotating shaft, and the other end of this rotating shaft is connected by the turning cylinder of spherical linkage-knee joint shaft coupling and transmission mechanism.
2, ball body of valve honing head according to claim 1, the thrust piece (3) that it is characterized by in the slip joint (2) is the compression spring.
