Abstract
The utility model discloses a kind of ceramic bar regulation chuck, including base and cover plate, the center of the base and cover plate is provided with hole, ceramic bar is passed through from hole, space between base and cover plate forms sliding groove, gripping block fills in described sliding groove, and the gripping block afterbody is equipped with set screw, the position for adjusting ceramic bar.The utility model is greatly reduced the processing cost and installation difficulty of assembled component, while so that set screw Impact direction is perpendicular to ceramic bar axial direction, it is to avoid set screw produces slip, keeps crystal growth stability.
Description
Technical field
The utility model is related to Czochralski crystal to manufacture field, more particularly to a kind of ceramic bar regulation chuck.
Background technology
Ceramic bar lifts the connecting rod of transmission device as seed rod and body of heater top in Czochralski crystal growth technique,
Need to ensure in growth course, when it rotates, circular runout is in the range of a very little, it is therefore desirable to which regulation chuck is installed,
For adjusting the ceramic bar centre of gyration, and play a part of fixed ceramic bar.Currently used ceramic bar adjusts chuck structure
As shown in figure 1, top view is as shown in Fig. 2 such regulation chuck structure is sufficiently complex, the processing cost of each part is higher, peace for figure
Dress is cumbersome with demounting procedure.Meanwhile, with Screw gasket plane it cannot be guaranteed that vertical, screw is easily produced the Impact direction of set screw
It is raw to slide, the component is influenceed to the fixation of ceramic bar, and then influences the stability of crystal growth.
Utility model content
The utility model purpose is to provide a kind of ceramic bar regulation chuck, simple structure, convenient disassembly, while have again
Good stability.
The technical scheme that the utility model is used is：A kind of ceramic bar adjusts chuck, including base and cover plate, the bottom
The center of seat and cover plate is provided with hole, and ceramic bar is passed through from hole, and the space between base and cover plate forms sliding groove, gripping block plug
Enter described sliding groove, wherein, gripping block afterbody is equipped with set screw, the position for adjusting ceramic bar.
Further, totally three pieces of the gripping block, circumferentially direction is uniformly arranged.
Further, the gripping block is in T shape, and its end recess is respectively mounted two springs, for gripping block
Ejection.
After adopting the above technical scheme, the beneficial effects of the utility model are：The utility model is greatly reduced assembling structure
The processing cost and installation difficulty of part, while so that set screw Impact direction is perpendicular to ceramic bar axial direction, it is to avoid set screw
Slip is produced, crystal growth stability is kept.
