Connected with screw or pin nut, briquetting and pin can be adjusted flexibly, positioning security reasonable accuracy is high, it is easy to operate fast
Victory, repeatable accuracy is high, and usage cycles are long, safeguards simple, greatlys save percussion spot welding clamping, spot welding and correction time, shortens
Production cycle；The thermal deformation during components welding is effectively controlled, welding quality, the drop of component can be improved using this fixture
Low percent defective.
Further, the clamping side that the fixture employs double inner arc multipoint positionings to the T-shaped plate of weld assembly, double outer arcs are compressed
Formula, it is to avoid one end is hanging, makes its stress balance.
Further, locating piece is positioned by the first screw support to weld assembly inner flow passage face, with the second screw pressure
Press tight weld assembly inner flow passage face, the key technology for component pipes' analysis requires on fixture to increase for controlling channel size
Keeper, for component, each single-piece wall is thin, the characteristics of yielding, adds blade anchor point.Simultaneously in the leaf basin of blade
With intersect (direct) positioning on blade back with T-shaped template hole site, stagger between each two anchor point a certain distance, make leaf basin and
Gap uniformity between blade back and type hole, meets joint clearance of brazing requirement.Both solder leakage problems had been solved, component weldering is controlled again
Torsional deformation in termination process.
