Abstract
These novel anchor clamps that belong to, concretely relates to barrel and otic placode welding jig. A barrel and otic placode welding jig, including the holding down plate, the guide pillar, the otic placode briquetting, the top board, the chuck, the pole of extending, the pole support of extending, the anchor clamps base, the plain washer, hexagon nut, hexagon head bolt, cylindric lock (14), the dish nut, mark closely the screw, the percentage table, wherein the anchor clamps base is the base of whole device, set up the holding down plate on the anchor clamps base, set up two parallel guide pillars on the holding down plate, set up on the guide pillar in the parallel top board of holding down plate, set up the otic placode briquetting on the top board. This neotype effect is: through application anti -deformation method, apply certain anti -deformation volume in advance to last barrel before the welding of upper tube base pin to offset the influence of welding deformation to the position degree of last barrel otic placode. Wherein the control method of anti -deformation size is the gland nut who screws up on the welding jig, then measures and control the pre -compaction deflection of going up the barrel with the percentage table.
Description
Technical field
Basis is novel belongs to fixture, is specifically related to a kind of cylinder and otic placode weld jig.
Background technology
Upper base is one of key components of high burnup nuclear fuel assembly, has the irreplaceable functions such as lifting, control rod entrance, bumper and absorbing shock.
Upper shell parts undertake in upper base guiding connecting tube, on the upper location of base central canal and the effect of connector of the lifting of fuel assembly and transport is provided.Therefore its manufacture difficult point also concentrates in the pillar hole system processing of parts and the position degree size Control of upper shell otic placode accordingly.
Due to upper base otic placode erection welding position relationship to fuel assembly lifting and transport interface, so required precision is high.And the welding position of otic placode and upper shell carries out on the face of cylinder, if the welding deformation in manufacturing is not controlled well, the circularity of upper shell can be affected, cause that the position degree of upper shell otic placode is overproof.
Prior art does not well solve the scheme of the problems referred to above.
Summary of the invention
This novel pin is to prior art defect, it is provided that a kind of cylinder and otic placode weld jig.
This novel technical scheme is: a kind of cylinder and otic placode weld jig, including lower platen, guide pillar, otic placode briquetting, top board, chuck, bar of extending, shaft bar of extending, clamp base, plain washer, hex nut, hexagon-headed bolt, straight pin 14, dish shape nut, mark closely screw, dial gauge, wherein clamp base is the base of whole device, clamp base arranges lower platen, lower platen arranges parallel two piece guide pillar, guide pillar is arranged at the top board that lower platen is parallel, top board arranges otic placode briquetting.
A kind of cylinder as above and otic placode weld jig, wherein, also set up shaft bar of extending on lower platen, arrange, extending, bar of extending on shaft bar, and the top of bar of extending arranges chuck, and chuck arranges hex nut, and the end of chuck arranges dial gauge.
A kind of cylinder as above and otic placode weld jig, wherein, described top board is fixed on guide pillar by plain washer and hex nut.
A kind of cylinder as above and otic placode weld jig, wherein, also set up dish shape nut between described chuck and hex nut.
This novel effect is: by using prestrain method, before upper base pin welds, upper shell is previously applied certain anti-deformation, thus offsetting the welding deformation impact on the position degree of upper shell otic placode.The control method of wherein reversible deformation size is to tighten the clamp nut on weld jig, then measures and control the prepressing deformation amount of upper shell with dial gauge.

Detailed description of the invention
As shown in accompanying drawing 1～5, a kind of cylinder and otic placode weld jig, including lower platen 1, guide pillar 2, otic placode briquetting 3, top board 4, chuck 5, extend bar 6, extend shaft bar 7, clamp base 8, plain washer (9, 12, 15), hex nut (10, 16), hexagon-headed bolt (11, 13), straight pin 14, dish shape nut 17, mark closely screw 18, dial gauge 19, wherein clamp base 8 is the base of whole device, clamp base 8 arranges lower platen 1, lower platen 1 arranges parallel two piece guide pillar 2, guide pillar 2 is arranged at the parallel top board of lower platen 14, top board 4 arranges otic placode briquetting 3.
Also setting up shaft bar 7 of extending on lower platen 1, arrange, extending, bar 6 of extending on shaft bar 7, the top of bar 6 of extending arranges chuck 5, and chuck 5 arranges hex nut 16, and the end of chuck 5 arranges dial gauge 19.
Described top board 4 is fixed on guide pillar 2 by plain washer 9 and hex nut 10.
Dish shape nut 17 is also set up between described chuck 5 and hex nut 16.
The use procedure of this fixture approximately as: first soldered cylinder and otic placode are fixed on lower platen and otic placode pressing plate, then hex nut is regulated, welded part is applied certain precompression, the value of this precompression can be read out by dial gauge, after being applied with precompression, welded part is welded, after having welded, welded part is taken off.
