Abstract
The utility model discloses a shell positioning clamp of a photomultiplier tube. The shell positioning clamp is mainly used for positioning and fixing an outer glass shell of the photomultiplier tube. According to the technical scheme, an upper supporting plate and a lower supporting plate are connected to form a support, an upper supporting block and a lower supporting block of the support are directly connected through a spring, and the bottom face of the lower supporting plate is provided with a fixed positioning block and a movable positioning block. As is proved by application, the shell positioning clamp is reasonable in structure and easy to operate, the phenomenon that a glass shell ball breaks due to uneven stress is completely eliminated during production, production requirements are met, and production cost is effectively reduced.
Description
Technical field
the utility model belongs to a kind of assembling jig of electron tube, is mainly used in the outer glass bulb location of photomultiplier to fix, and the location that also can be used for other similar irregular device outer case is fixed.
Background technology
photomultiplier (see figure 1) is the photoelectric device that a kind of high energy particle is surveyed, and is mainly used in scientific research, national defence and special industry, and it is doubled by negative electrode 1, glass bulb ball 2, MCP() assembly 3, sealing-in dish 4 etc. form.The shell of photomultiplier is glass bulb ball, due to manually-operated otherness, as different with the angle of cylindrical changeover portion sealing-in in spheroid, causes the uniformity of glass bulb poor.The negative electrode of photomultiplier make and the important procedure of sealing-in in, need to glass bulb ball be positioned and is fixedly clamped, in operation, often there is glass bulb discontinuity and break or situation that cannot clamping, badly influence the increase with cost that completes of manufacturing schedule.This problem has become a difficult problem anxious to be resolved in production.
Utility model content
the main technical problems to be solved in the utility model and object are: the technical barrier existing in producing according to photomultiplier, count a kind of otherness that adapts to photomultiplier glass bulb ball, there is the fixing fixture of elasticity and capable of regulating, the phenomenon that overcomes glass bulb ball discontinuity and break, reaches and meets Production requirement and reduce costs.
main technical schemes of the present utility model: mounting plate is connected to form support by nine screw thread poles and bottom plate, distance between mounting plate and bottom plate can be adjusted by screw thread pole, the right upper supporting block is connected by spring with lower tray, left side upper supporting block is connected by spring with lower movable tray, lower tray is bolted on mounting plate, on mounting plate, be bolted two guide rails, two guide rails coordinate with the groove of lower movable tray bottom, make lower movable tray and lower tray accurate contraposition, underrun bolt at bottom plate is installed locating piece, activity orientation piece is connected with locating piece by the bolt of side, at an adapter sleeve of the bottom plate bottom surface portion of keeping right assembling, adapter sleeve is connected with the rotating shaft of equipment.
the utility model proves by practical application: positioning fixture structure is reasonable, simple to operate, in the negative electrode making of photomultiplier and the operation of sealing-in, stopped the phenomenon generation that glass bulb ball breaks because of discontinuity completely, met Production requirement and effectively reduced production cost.

The specific embodiment
with reference to Fig. 2,3, main technical schemes of the present utility model is described: the utility model is comprised of upper supporting block 5, lower tray 6, mounting plate 7, screw thread pole 8, adapter sleeve 9, bottom plate 10, locating piece 11, activity orientation piece 12, bolt 13, lower movable tray 14, guide rail 15, spring 16 etc.Concrete structure: mounting plate 7 is connected to form support by nine screw thread poles 8 and bottom plate 10, distance between mounting plate 7 and bottom plate 10 can be adjusted by screw thread pole 8, the right upper supporting block 5 is connected by spring 16 with lower tray 6, left side upper supporting block 5 is connected by spring 16 with lower movable tray 14, lower tray 6 is bolted on mounting plate 7, on mounting plate 7, be bolted two guide rail 15(and see Fig. 4), two guide rails 15 coordinate and (see Fig. 8 with the groove L of lower movable tray 14 bottoms, 9), make lower movable tray 14 and lower tray 6 accurate contrapositions, underrun bolt at bottom plate 10 is installed locating piece 11, activity orientation piece 12 is connected with locating piece 11 by the bolt of side, at an adapter sleeve 9 of the bottom plate 10 bottom surface portion of keeping right assemblings, adapter sleeve 9 is connected with the rotating shaft of equipment.
with reference to Fig. 2, operation principle of the present utility model: when glass bulb ball 2 is installed, first the upper supporting block 5 of lower movable tray 14 and top left is removed, sealing-in disk activity locating piece 12 is thrown off, glass bulb ball 2 is installed to the right upper supporting block 5, after on lower tray 6, again the upper supporting block 5 on lower movable tray 14 and the left side is drawn close along the upper supporting block 5 on the downward tray 6 of guide rail 15 and the right, form closed cylinder, and with bolt 13, lower movable tray 14 is stopped tightly on guide rail 15, two upper supporting blocks 5 and lower tray 6, between lower movable tray 14 due to the elastic force of spring 16, there is certain gap, after glass bulb ball is installed, gap remains between 5-10 millimeter.
with reference to Fig. 2, key technology of the present utility model is: mounting plate 7 is connected by screw thread pole with bottom plate 10, and upper supporting block 5, lower tray 6 and lower movable tray 14 all have spring 16 to connect, and tray has three activities, and one fixing; When glass bulb ball 2 is installed, due to the flexible support effect of spring, between upper and lower tray, there is the gap of 5-10 millimeter, can disperse the stressed of balance glass bulb ball, to the individual difference of glass bulb ball shape, can automatically adapt to adjusting, make tray and glass bulb ball is full and uniform agrees with, avoid the damage of glass bulb ball; Utilize the gap between upper and lower, tray, the levelness that can connect dish to glass bulb ball sealing regulates simultaneously, and this is the Reliable guarantee to photomultiplier sealing-in quality.
