Description
Technical field
The utility model relates to a kind of crystal edge for semicon industry, refers more particularly to a kind of rewinding of crystal edge.
Background technology
The rewinding of current crystal edge, its structure generally includes: the rewinding body involuted with the fixed connecting piece matched by mounting flange by the upper and lower hemisphere with spherical inner chamber, described upper and lower hemispheroidal top is respectively arranged with the Gripping platform be parallel to each other, upper and lower hemispheroidal end face and involutory surface offer semicircular annular seal groove respectively, in annular seal groove, is provided with sealing ring.When mounted, upper and lower hemispheroidal location is very difficult for this rewinding, is easy to dislocation, thus has influence on installation accuracy; In addition, owing to only having installed one sealing ring between upper and lower hemisphere, sealing effectiveness is poor, in Long-Time Service process, the phenomenon of lapping liquid seepage often occurs, affects grinding effect.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of and locate very convenient and can improve the rewinding of the crystal edge of sealing effectiveness.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of rewinding of crystal edge, comprise: by having the upper of spherical inner chamber, the rewinding body that lower hemisphere involutes by being fixedly connected with mechanism, on, the top of lower hemisphere is respectively arranged with the Gripping platform be parallel to each other, on, the involutory surface of lower hemisphere is respectively arranged with mutually stagger outer stretch out boss and interiorly stretch out boss, make, the equal forming station scalariform of involutory surface of lower sphere, the lateral surface inside stretching out boss and the medial surface stretching out boss are outward the guiding conical surface cooperatively interacted, inside stretch out on the end face of boss and the end face of upper hemisphere and offer semicircular first annular seal groove respectively, this is provided with the first sealing ring in the first annular seal groove, stretch out outward on the end face of boss and the end face of lower hemisphere and offer semicircular second annular seal groove respectively, this is provided with the second sealing ring in the second annular seal groove.
As a kind of preferred version, in the rewinding of described crystal edge, the described mechanism that is fixedly connected with comprises: the mounting flange being separately positioned on upper and lower hemisphere bead, this a pair mounting flange offers some fixed vias to matching, these are some is equipped with set bolt respectively in fixed via, twists and be provided with hold-down nut after set bolt passes fixed via.
As a kind of preferred version, in the rewinding of described crystal edge, described fixed via is circumferentially evenly arranged on corresponding mounting flange.
As a kind of preferred version, in the rewinding of described crystal edge, described Gripping platform is also respectively arranged with positioning boss.
The beneficial effects of the utility model are: stretch out boss because the utility model is provided with mutually stagger outer on upper and lower hemispheroidal involutory surface and interiorly stretches out boss, and, the lateral surface inside stretching out boss and the medial surface stretching out boss are outward the guiding conical surface cooperatively interacted, make upper and lower hemispheroidal installation location very convenient, improve upper and lower hemispheroidal installation accuracy; In addition, owing to being provided with not the first sealing ring at grade and the second sealing ring between upper and lower hemispheroidal involutory surface, and the inside and outside guiding conical surface stretching out boss also serves sealing function, thus substantially increases sealing effectiveness.In addition, the positioning boss be arranged on Gripping platform can make the location that installs additional of whole rewinding more precisely facilitate.
