Abstract
A kind of in the process of two porcelain shells docking effective, the two self-align assembly structure of porcelain shell of the vacuum switch tube that can greatly enhance productivity of axiality, comprise the upper porcelain shell of two tubuloses and lower porcelain shell, retainer ring is provided with between upper porcelain shell and the interface of lower porcelain shell, be positioned at inner ring place in retainer ring bottom surface and be provided with annular boss, the outer wall of described annular boss is circumferentially laid with multiple acclivitous spacing thorn, and described spacing thorn leans at lower porcelain shell inwall; Be embedded with the radome of tubulose at the inner ring of described retainer ring, and be positioned at above described retainer ring at the outer wall of radome and be circumferentially laid with multiple spacing bag, spacing bag leans porcelain shell inwall on described.
Description
Technical field
The utility model relates to the two self-align assembly structure of porcelain shell of a kind of vacuum switch tube.
Background technology
In the process of vacuum switch tube docking, in order to make two porcelain shell internal diameter coaxial lines, need to carry out circumference grinding process at the outer wall of two porcelain shells, the outline of two porcelain shell outer walls is coincide and two porcelain shell coaxial lines, again by fixture by two porcelain shell hoops together, and its contact-making surface is welded.Because grinding process tolerance is comparatively large, causes two porcelain shell porcelain shell axialities low, and greatly reduce production efficiency.
Summary of the invention
The utility model is to solve the problem, provide a kind of in the process of two porcelain shells docking effective, the two self-align assembly structure of porcelain shell of the vacuum switch tube that can greatly enhance productivity of axiality.
Technical solution of the present utility model is: the two self-align assembly structure of porcelain shell of a kind of vacuum switch tube, comprise the upper porcelain shell of two tubuloses and lower porcelain shell, its special character is: between upper porcelain shell and the interface of lower porcelain shell, be provided with retainer ring, be positioned at inner ring place in retainer ring bottom surface and be provided with annular boss, the outer wall of described annular boss is circumferentially laid with multiple acclivitous spacing thorn, and described spacing thorn leans at lower porcelain shell inwall; Be embedded with the radome of tubulose at the inner ring of described retainer ring, and be positioned at above described retainer ring at the outer wall of radome and be circumferentially laid with multiple spacing bag, spacing bag leans porcelain shell inwall on described.
The two ends up and down of described radome are bead-like, prevent from causing scuffing to staff or other parts in assembling process.
The beneficial effects of the utility model are:
1, radome and retainer ring closely cooperate, and the spacing bag on radome leans at upper porcelain shell inwall, and the spacing thorn on retainer ring leans at lower porcelain shell inwall, effectively prevent porcelain shell and the radial displacement of lower porcelain shell, ensure that the axiality of porcelain shell and lower porcelain shell.
2, eliminate upper porcelain shell and lower porcelain shell outer wall are polished, and by the assembling process of fixture by upper porcelain shell and lower porcelain shell stirrup, structure is simple, easy for installation, improve production efficiency greatly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the upward view of retainer ring in Fig. 1.
In figure: the upper porcelain shell of 1-, porcelain shell under 2-, 3-retainer ring, 4-annular boss, the spacing thorn of 5-, 6-radome, the spacing bag of 7-.
Embodiment
As shown in the figure, the two self-align assembly structure of porcelain shell of a kind of vacuum switch tube, comprise the upper porcelain shell 1 of two tubuloses and lower porcelain shell 2, retainer ring 3 is provided with between upper porcelain shell 1 and the interface of lower porcelain shell 2, be positioned at inner ring place in retainer ring 3 bottom surface and be provided with annular boss 4, the outer wall of described annular boss 4 is circumferentially laid with multiple acclivitous spacing thorn 5, and described spacing thorn 5 leans at lower porcelain shell 2 inwall; Be embedded with tubulose and up and down two ends are the radome 6 of bead-like at the inner ring of described retainer ring 3, and be positioned at above described retainer ring 3 at the outer wall of radome 6 and be circumferentially laid with multiple spacing bag 7, spacing bag 7 leans porcelain shell 1 inwall on described.
During operation, first radome 6 is penetrated in retainer ring 3 from the top down, then upper porcelain shell 1 is enclosed within radome 6 outer and make upper porcelain shell 1 bottom lean at retainer ring 3 upper surface, again lower porcelain shell 2 is enclosed within radome 6 outer and make lower porcelain shell 2 upper end lean at retainer ring lower surface, finally upper porcelain shell 1 and lower porcelain shell 2 are welded on retainer ring 3, complete operation.
Claims (2)
1. the two self-align assembly structure of porcelain shell of vacuum switch tube, comprise the upper porcelain shell of two tubuloses and lower porcelain shell, it is characterized in that: between upper porcelain shell and the interface of lower porcelain shell, be provided with retainer ring, be positioned at inner ring place in retainer ring bottom surface and be provided with annular boss, the outer wall of described annular boss is circumferentially laid with multiple acclivitous spacing thorn, and described spacing thorn leans at lower porcelain shell inwall; Be embedded with the radome of tubulose at the inner ring of described retainer ring, and be positioned at above described retainer ring at the outer wall of radome and be circumferentially laid with multiple spacing bag, spacing bag leans porcelain shell inwall on described.
