Description
Technical field
The utility model belongs to vehicle body cabin welding field, is specifically related to a kind of adjustable welding auxiliary mould structure.
Background technology
At present, in trial production of new products stage (before new product volume production), due to equipment when trial-production equipment and volume production, there is some difference, equipment component cannot realize the comprehensive welding of all vehicles, particularly vehicle body cabin assembly, vehicle body cabin assembly is by left longeron assembly, right vertical beam assembly, front panel assembly etc. 3 part forms, vehicle body cabin is due to its complex structure, space is little, the features such as solder joint is intensive, causing vehicle body cabin assembly part solder joint to be interfered due to jaw and welding gun under clamp working-station causes part solder joint to realize, need the jaw of fixture to open to carry out repair welding operation.Now, because vehicle body cabin assembly part solder joint cannot realize under chuck jaws clamped condition, it is not firm that each sheet metal component connects, open in process of patch weld in chuck jaws, owing to lacking operative constraint between each sheet metal component, be in free state, welding deformation phenomenon is easily there is in process of patch weld, thus cause vehicle body cabin assembly precision on the low side, have a strong impact on vehicle performance, as: abnormal sound, comfortableness etc.
The trial production of new products stage, in the assembly process of patch weld of vehicle body cabin, for preventing easily occurring in process of patch weld that the left and right longeron in cabin is opened or contraction situation outward, usual employing front anticollision beam of automobile is fixed vehicle body cabin, realizing its constraint to vehicle body cabin assembly, reducing to a certain extent because welding the distortion caused.
Front anticollision beam of automobile is due to its reasons in structure, mainly through bolt, front anti-collision beam is fixed on the left-right longeron of vehicle body cabin, owing to front anticollision beam of automobile there being 4 installing holes, consider automobile body welding precision factor and assembling capacity, on front anticollision beam of automobile, 4 installing holes are compared with vehicle body cabin longeron installing hole about 2.0mm bigger than normal.Even if outer or the situation of contraction appear in the left and right longeron of vehicle body cabin assembly for various reasons (in manufacture process accumulated tolerance, holder status instability etc.), its front anti-collision beam all can be assemblied on the left-right longeron of vehicle body cabin.Thus be difficult to ensure that between the left-right longeron of cabin, size repair welding meets product design requirement after completing.There is following defect in prior art:
1, front anti-collision beam length is unadjustable, when the vehicle body cabin left and right girder space of assembly is bigger than normal or less than normal, cannot carry out length adjustment, makes the designing requirement of repair welding front left and right girder space size conforms.
2, front anti-collision beam assembly precision is lower, its installing hole tolerance is relatively loose, and fitting allowance is comparatively large, as long as longeron left and right spacing deviation controls within ± 4.0mm, front anti-collision beam all can realize assembling, and cabin left-right longeron spacing deviation wants control overflow within ± 1.5mm.This kind of fixed form effectively cannot control repair welding after engine room left-right longeron spacing dimension.
Utility model content
The purpose of this utility model is to provide a kind of adjustable welding auxiliary mould structure, non-adjustable to solving the front anti-collision beam length existed in prior art, and the problem that front anti-collision beam assembly precision is low.
To achieve these goals, the utility model provides a kind of adjustable welding auxiliary mould structure, and comprise double thread adjusting rod, the left end of described double thread adjusting rod is threaded connection left connecting rod, and the end of described left connecting rod connects left installing plate; The right-hand member of described double thread adjusting rod is threaded connection right connecting rod, and the end of described right connecting rod connects right installing plate; Described left installing plate and described right installing plate are respectively equipped with the alignment pin for installing front anti-collision beam.
Preferably, described double thread adjusting rod is multidiameter structure, and the little axle at two ends is provided with screw thread; The front end of described left connecting rod and the front end of described right connecting rod are equipped with the screw matched with described screw thread.
Preferably, be six diamond structures in the middle part of the macro-axis of described double thread adjusting rod.
Preferably, described alignment pin one group and keep at a certain distance away between two.
Preferably, the top of described alignment pin is fixed on left installing plate or right installing plate by nut, and the bottom of described alignment pin, through left installing plate or right installing plate, is fastened on the longeron front anti-collision beam installing plate of cabin.
Preferably, the bottom of described alignment pin is pyramidal structure.
Effect of the present utility model is: adopt scheme described in the utility model, by adopting adjustable structure, makes front anti-collision beam adjustable length, and structure is simple simultaneously, easy to operate, and can improve body cutout position precision preferably.Cabin after adopting this frock to weld, its position, hole precision is far longer than prior art.
