Description
Technical field
The present invention relates to the erection welding works in the assembling field of airborne communication cabinet frame, specifically a kind of metal framework
Dress.
Background technology
Frame is welded by upper cover plate, lower cover, the first lattice framing, the second lattice framing and rear panel using vacuum electron beam group,
The frame is sophisticated product, and length, width and height dimensional tolerance is required after welding as ± 0.2mm, meanwhile, the difference of above and below diagonal needs not
More than 0.25mm, the control requirement of welding deformation is high.In addition, according to GJB1718A-2005《Electron beam welding》Requirement, simultaneously
In order to ensure frame postwelding appearance and size, assembling quality must meet unfitness of butt no more than 0.2mm and uniformly, gap is not
More than 0.1mm and uniformly.
Frame is made of five parts, and weld seam is the composite welds of four " L " type weld seams and two line-styled weld seams, symmetrically
Upper and lower surface is distributed in, common limit-type frock can not realize that six weld seams complete welding in the case where only taking out a stove vacuum.
Patent CN104842095A《Frame prevents deformation frock》In refer to use using block come the horizontal stroke of limiting frame
To movement, moving up and down for frame to be welded is limited using limited block, by the limitation in several directions, then is welded, it can
Prevent the deformation of frame in the welding process, but the frock adjusts the effect unobvious of fit-up gap, and to the control journey of deformation
Spend relatively low, the welding of unsuitable high-precision product.
Patent CN206296611U《A kind of efficient frame welding frock》In mention using card slot framework component, and lead to
It crosses and cover board is set on card slot, limiting frame moves up and down, which can improve the welding precision of frame, but may be only available for putting down
Surface frame frame is not suitable for solid type frame, in addition, the frock is relatively low to Deformation control degree.
The content of the invention
To overcome unsuitable solid type frame in the prior art, to the deficiency of Deformation control effect difference, the present invention
Propose a kind of erection welding frock of high-precision frame structure.
The present invention includes two clamping plates used in pairs, four pressing plates and pull rod.Four pressing plates are divided into two groups, point
It is affixed with the wedge block on described two clamping plates not by way of grafting, and two groups of pressing plates is made to be located at the two of two clamping plates respectively
Side.The middle part of pull rod and one end of the pull rod are respectively charged into the through hole of described two clamping plate geometric centers, and are fastened by nut；
Interference engagement between the pull rod and clamping plate through hole.The other end of the pull rod is located at outside the side clamping plate, is used for and vacuum electronic
The chuck of beam welding machine is connected.
Rectangular gap is processed respectively on four angles of clamping plate.It should there are four protrusion on described one surface of clamping plate
The wedge block on surface；The wedge block is divided into two groups and is symmetrically distributed at the two sides of the clamping plate, wherein positioned at described each
L-shaped weld seam lower end 5mm of the upper surface of the wedge block of side upper end away from the chassis frame upper end after assembling, positioned at each side
The lower surface of the wedge block of lower end is away from the lower weld seam 5mm on the chassis frame after assembling.In another middle side edge of the clamping plate
There is the boss of bar shaped, for the /V of chassis frame to be welded.It is provided at the edge of the clamping plate and the chassis frame shape to be welded
The groove that shape is adapted, for the positioning of the chassis frame to be welded.The through hole of installation pull rod is useful in the geometric center of clamping plate.
There is center hole in the end face that the pull rod is equipped with nut one end.
The both ends of the pressing plate are the lozenges with the wedge block cooperation on clamping plate.
The present invention is for vacuum electron beam welding assembling chassis cover plate, lower cover, the second lattice framing, the first lattice framing and below
Ensure unfitness of butt joint, the rotation for controlling welding deformation and generating frame in plate, can ensure unfitness of butt weld, and to entire
Frame is constrained, and prevents frame from deforming upon in the welding process, meanwhile, frock can make frame generate rotation, make all welderings
Seam can complete welding under a stove vacuum, improve welding efficiency and quality.
The present invention can realize the erection welding of five components of frame.The present invention adjusts assembling quality and control welding deformation
Principle be：First, with accurately strip grooves position dimension, each component of positioning framework ensures the overall dimensions of frame, with pull rod
Structure tightens together frame, ensures its fit-up gap.Secondly, by wedge structure, pressing plate is made to generate pressing force to frame,
Ensure misalignment, meanwhile, by the constraint of strip grooves, the pressing force of pressing plate, make entire frame structure is in restrained condition, prevents
The generation of welding deformation.
Experiment proves that the frame after being assembled using erection welding frock proposed by the present invention passes through vacuum electron beam welding
Afterwards, appearance of weld is good, postwelding length, width and height dimensional tolerance within ± 0.2mm, the difference of above and below diagonal no more than
0.25mm。
