Description
Technical field：
This utility model is related to a kind of welding jigs and fixtures, and in particular to a kind of articulated stand weld jig.
Background technology：
Articulated stand saves car body, on articulated system as the important component part of linkwork for before and after connection two
The actuating device of second section car body is installed, for guaranteeing between compartment in horizontal direction, longitudinally perpendicular and horizontal vertical plane
Rotate.It is one of the core technology for realizing Vehicular turn, high cross-country power and carrying.Articulated stand should meet general layout
Requirement, ensure that own wt is little again, and with enough stiffnesses.The Strength Safety of articulated stand directly affects entirety
The normal operation of chassis system, so its safety is extremely important, from the functional analyses of linkwork, the shape of articulated stand assembly
Shape and size directly affect the realization of articulated all-terrain vehicle tactics index, it is ensured that the quality of production of articulated stand, processing performance
It is particularly important.
The difficult point of design articulated stand weld jig is derived from three aspects：When the first, producing in batches, after each support tack welding
There is specificity to a certain extent, clamping device can not be designed according to theoretical size, it is right if the design of clamping device is loose
It is poor in the control ability of deformation, lose the meaning of tight clamping；2nd, this part welding stress is very big, using traditional axis hole
Its hinged seat is fixed in cooperation, because deformation tendency makes the swelling that rubs between support and fixture after welding, locating shaft, block will be caused to pull out
Go out it is very difficult, if taking short axle to fix, the effect that locating piece small area of contact does not have again；3rd, 4 hinged seat conducts
Forge piece, profile is irregular, and each with the construction featuress of oneself, the mutual alignment size of 4 hinged seats of priority control is
Another difficult point；4th, because cradle weld prescription is very strict, so horizontal position can be in when must assure that per pass weld seam
Welding is put, this is required in switching process repeatedly, fixture can remain tightening state.
The content of the invention：
This utility model provide a kind of articulated stand weld jig, articulated stand can be carried out it is stable be fixedly clamped,
