Detailed description of the invention
Below in conjunction with the accompanying drawings and this utility model is described in further detail by specific embodiment.
As it is shown in figure 1, spentnuclear fuel associated component shear treatment fixture under water includes clamping device and locking mechanism two parts.
As shown in Figure 2 a and 2 b, clamping device includes base plate 1, clamp 2, column 11 and side plate 3, is additionally included on column 11 pressing plate 4, the compact heap 5 installed.By screw fixed installation side plate 3 and clamp 2 on base plate 1, side plate 3 is positioned at the forward position of base plate 1.Clamp 2 is L-shaped.
Column 11 has two both sides being separately mounted to base plate 1, passes through bolt 6, spring 8 and round nut 9 at column 11 installation fixed above pressing plate 4, pressing plate 4 compact heap installed above 5, pressing plate 4 and compact heap 5 and is connected.
In order to further such that side plate 3 and column 11 are installed stable, be connected horizontally between side plate 3 and column 11 by connecting plate 10, a connecting plate 10 is installed in side.In associated component 12 word handle be arranged between clamp 2 and side plate 3, associated component 12 be axially located through clamp 2 and side plate 3 realizes；Pressing plate 4 and compact heap 5 realize the location of the radial direction of associated component 12；
Clamping device of the present utility model realizes lock function by the locking mechanism of design, and its structure is as follows.As shown in Figure 3 a and Figure 3 b shows, locking mechanism includes spur gear 14, gear shaft 16, worm screw 17, worm gear 18, rotating disk 19, worm-wheel shaft 20 and the latch 21 being arranged in deceleration box 13.
