Abstract
The utility model belongs to fixture, more particularly to a kind of control assembly connection handle parts group welding equipment welding fixture.It includes pedestal, and through hole is set in pedestal, and the through hole is used to accommodate the part for needing to weld, and sets bushing in through-holes, cross through hole is provided with pedestal side wall, and Top fastening screw is set in cross through hole, and Top fastening screw is used to hold out against soldered part.Remarkable result of the present utility model is：(1) increase radiating, be advantageous to improve welded seam quality and deformation.(2) after new coolant jacket is inserted in connection handle cylinder, Top fastening screw is tightened, coolant jacket and connection handle cylinder is had good contact.Using the preferable copper of radiating effect as coolant jacket main body, and the radiating contact surface of coolant jacket and connection handle cylinder is increased, shown through actual use, in the case where not changing welding condition, connection handle drum surface non-oxidation color after welding.(3) Successful utilization manufactures production to the fixture in fuel assembly control assembly connection handle, and presentation quality is good.
Description
Technical field
The invention belongs to fixture, more particularly to a kind of control assembly connection handle parts group welding equipment welding fixture.
Background technology
Under existing welding condition, after the welding of fuel assembly connection handle assembling parts, have one on connection handle cylinder body outer wall
The oxidation tint of the obvious yellow of layer, the preceding surface of assembly welding of the connection handle part is sandblasting state, to remove this layer of oxygen
Change color, sandblasting need to be used or brushed away with stainless steel and removed.Because connection handle part has spring and spring base, gone according to blasting craft
Except oxidation tint, for tiny sand grains possibly into spring and spring base, being run in reactor has certain risk.If use stainless steel wire
Brush away and remove oxidation tint, it will destroy connection handle part cylindrical outer tube surface sand-blasting state, outward appearance is impacted.Have a strong impact on production
Product presentation quality, and the oxidation tint is in reactor, it is possible to meeting accelerated corrosion, power station user repeatedly query and required
Except the oxidation tint.
The difficult point of the technology is：It can not be brushed away with stainless steel wire and remove oxidation tint, so that destroying the spray of connection handle drum surface
Sand state, and the technique of sandblasting again can not be used to remove oxidation tint.The fixture of design need to ensure postwelding non-oxidation color, and can not
Scratch product external surfaces.
The content of the invention
The present invention is directed to prior art defect, there is provided a kind of control assembly connection handle parts group welding equipment welding fixture.
What the present invention was realized in：A kind of control assembly connection handle parts group welding equipment welding fixture, including pedestal, in pedestal
Middle setting through hole, the through hole are used to accommodate the part for needing to weld, set bushing in through-holes, transverse direction is provided with pedestal side wall
Through hole, sets Top fastening screw in cross through hole, and Top fastening screw is used to hold out against soldered part.
A kind of control assembly connection handle parts group welding equipment welding fixture as described above, wherein, set in Chuck top spacing
Block, the limited block are fixedly connected by attachment screw with pedestal.
A kind of control assembly connection handle parts group welding equipment welding fixture as described above, wherein, pedestal is copper.
A kind of control assembly connection handle parts group welding equipment welding fixture as described above, wherein, bushing is austenitic stainless steel.
A kind of control assembly connection handle parts group welding equipment welding fixture as described above, wherein, bushing is opened through upper vertically
Under groove.
A kind of control assembly connection handle parts group welding equipment welding fixture as described above, wherein, the size of bushing fluting is
1mm。
A kind of control assembly connection handle parts group welding equipment welding fixture as described above, wherein, limited block is stainless steel.
The present invention remarkable result be：(1) increase radiating, be advantageous to improve welded seam quality and deformation.(2) new cooling
After being inserted in connection handle cylinder, Top fastening screw is tightened, coolant jacket and connection handle cylinder is had good contact.Using radiating effect compared with
Good copper increases the radiating contact surface of coolant jacket and connection handle cylinder as coolant jacket main body, shows through actual use,
In the case of not changing welding condition, connection handle drum surface non-oxidation color after welding.(3) fixture Successful utilization in
The manufacture production of fuel assembly control assembly connection handle, presentation quality are good.
Brief description of the drawings
Fig. 1 connection handles part welds schematic diagram.
Fig. 2 is connection handle part welding assembly weld jig schematic diagram.
In figure：1. weld seam, 2. connection handle cylinder body outer wall oxidation tints, 3. limited blocks, 4. attachment screws, 5. pedestals, 6. connections
Shank part, 7. bushings, 8. Top fastening screws.
Embodiment
As shown in Figures 1 and 2, a kind of control assembly connection handle parts group welding equipment welding fixture, including pedestal 5, in pedestal 5
Middle setting through hole, the through hole are used to accommodate the part for needing to weld, set bushing 7 in through-holes, horizontal stroke is provided with the side wall of pedestal 5
To through hole, Top fastening screw 8 is set in cross through hole, Top fastening screw 8 is used to hold out against soldered part.
Limited block 3 is set on the top of pedestal 5, the limited block 3 is fixedly connected by attachment screw with pedestal 5.
The use process of the application device approximately as：
● unscrew the Top fastening screw on fixture, fixture is loaded to the connection handle part assembled as shown in Figure 2.
● tighten the Top fastening screw on fixture.
● shank part assembly is welded to connect, is cooled down 15 minutes after welding.
● unscrew Top fastening screw, remove weld jig.
Fixture is divided into two large divisions, fixture cooling main body and limited block.
● fixture cools down main body
Fixture cooling main body is made up of outer layer pedestal, internal layer bushing and Top fastening screw.Outer layer pedestal is that radiating effect is preferable
Copper sheathing, in order to avoid set coolant jacket when, workpiece sand blasted surface causes copper to stain with coolant jacket Relative friction.
One layer of austenitic stainless steel consistent with workpiece material of liner, inner liner stainless steel set longitudinal direction open one and run through small
Groove, to ensure that fixture cools down main body with having gap during the assembling of connection handle cylinder, prevent from scratching, and ensure liner when screw is held out against
Gapless between set and connection handle cylinder, with air exclusion, so neck bush is slotted, size is 1mm.
● limited block
Using stainless steel, for cooling down the positioning of main body and connection handle.
