The welder could not see the bottom of the groove,and the formation of a dead angle caused inconvenience in welding,and the weld itself had quality problems.Therefore,this repairing force and method reduce the strength of the supporting beam.When the hole is machined,the drill bit and the tap are unevenly stressed,and the processing is difficult.It is easy to waste,so the hole processing depth is only 12mm,and the effective length of the thread is only about 7mm.The sub-frame pin fixing
Bolts are screwed in shallower,and the loader is vibrating when used.The bolts are easy to loosen and fall off due to structural constraints.Although the sub-frame pin does not fall off,it can be rotated in the hole to wear the support hole.
The orifice plate is similar to the peeling because the cut arc can be adjusted by the sander,and the gap between the new orifice and the support beam stump is small,so the radial thermal deformation during welding is reduced.Due to the increase in size and the same axial deformation,the change in the angle of the hole axis is smaller than the original method,depending on the size relationship.Convenient ping connection and welding of the plate is the welding of the plate and the plate.Due to the increase of the diameter,the arc of the welding is close to the straight line.The improved repair method is to repair the method.The groove is facing the large side of the opening,and the weld can be directly seen.At the bottom,welding is very convenient.When the walking operation is performed,the pressure of the torque converter oil pressure gauge is always zero,indicating that no pressure oil enters the torque converter and the clutch,and the torque converter and the clutch are completely inoperable.The support hole is integrated with the support beam to completely eliminate the gap between the sleeve and the support beam.The strength at the support hole is greatly enhanced compared with the original scheme.At the same time,due to the large opening of the groove,the plate and the plate are butt welded,and the strength of the support beam is The change is small,the orifice plate is made of 16Mn material,and the wear resistance of the hole is also improved.The joint strength is greatly enhanced.The cut arc can be trimmed by a sander,and then the hole plate can be worn by the positioning shaft,and the positive position can be welded to complete the repair work.
