Description
Technical field
The present invention relates to welding tooling technical field, especially a kind of frame assembly welding error prevention device.
Background technology
Carbon dioxide gas arc welding is a kind of common welding manner, and it is carried out by protective gas of carbon dioxide gas
The method of welding, and robot carbon dioxide gas arc welding is because flexibility ratio is high, welding precision is high, product quality is relatively stablized and produces
Can be big the characteristics of, it is used for the welding of the large-scale weldment such as frame assembly.Vehicle frame sheet metal component is passed through into multiple clamp body clampings in weldering
Connect on the base plate of workbench, clamp body includes installing plate, positioning support, chuck and retaining mechanism, chuck is fixedly installed in positioning
On bearing, positioning support is connected by installing plate with the base plate of welding bench, by between the sheet metal component insertion chuck of vehicle frame, is used
After retaining mechanism locks sheet metal component, weld job is carried out, but there is following deficiency in this technical scheme：Welding heat is big, and zero
The part effect of being expanded with heat and contract with cold is yielding.And error-proofing technique is one of important content of Fixture Design, it is then anti-to prevent machining deformation
A part for wrong technology, further reduces welding deformation, is the problem that welding processing is constantly studied.
The content of the invention
It is an object of the invention to provide a kind of frame assembly welding error prevention device, it is total that this device can solve existing vehicle frame
The problem of deformation is also easy to produce into weldment present in welding.
In order to solve the above problems, the technical solution adopted by the present invention is：This frame assembly welding error prevention device includes
Clamp body, the clamp body includes installing plate, positioning support, chuck and retaining mechanism, the positioning support and the installing plate
Connection, the chuck is fixedly installed on the positioning support, the chuck be fixedly connected on it is many on the positioning support
Individual clamping limb, is provided with profiling block between the multiple clamping limb, the retaining mechanism is the lock being installed on the clamping limb
Tight bolt.
In the technical scheme of above-mentioned frame assembly welding error prevention device, more specifically technical scheme can also be：The folder
Gripping arm includes two the first clamping limbs being oppositely arranged and second clamping limb, second clamping limb and the profiling block
Clamping direction is vertical with the clamping direction of first clamping limb and the profiling block, is respectively mounted on first clamping limb
Clamping screw is stated, second clamping limb has the alignment pin protruded to clamping direction.
Further, the profiling block includes that the first profiling block being installed on positioning support is imitated with being connected to described first
Two the second profiling blocks of shape block both sides, the second profiling block located at the first profiling block and first clamping limb it
Between, the second profiling block has spacing shoulder.
Further, it is provided with pad between the second profiling block and the first profiling block.
By adopting the above-described technical solution, the present invention has the advantages that compared with prior art：Using profiling
Block can efficiently reduce sheet metal component and expand with heat and contract with cold deformation, and positioning is reliable, improves the stability of welding product quality, reduces and does over again
With the waste of resource, beneficial to improve production capacity.
Brief description of the drawings
Fig. 1 is the structural representation that this frame assembly welds error prevention device.
Fig. 2 is the right view of Fig. 1.
Fig. 3 is the schematic diagram that this frame assembly welding error prevention device clamps vehicle frame sheet metal component.
Specific embodiment
The invention will be further described for embodiment below in conjunction with the accompanying drawings：
Frame assembly welding error prevention device shown in Fig. 1 and Fig. 2 is the part in large-scale soldering set, and it is a clamp body,
The clamp body mainly includes installing plate 1, positioning support 2, clamping limb and clamping screw 6, and installing plate 1 is used to be installed on clamp body
On the base plate of welding bench, positioning support 2 is flexibly connected with installing plate 1, and clamping limb is fixedly installed on positioning support 2, folder
Gripping arm is the first clamping limb 5 and second clamping limb 7 that two be fixedly connected on positioning support 2 are oppositely arranged, at this
It is provided with the profiling block matched in welding workpiece between a little clamping limbs, the clamping direction of the second clamping limb 7 and profiling block and the
The clamping direction of one clamping limb 5 and profiling block is vertical, and clamping screw 6, the second clamping limb are mounted on two the first clamping limbs 5
7 have the alignment pin 8 protruded to clamping direction；Profiling block includes the first profiling block 3 being installed on positioning support 2 and is connected to
Two the second profiling blocks 4 of the both sides of the first profiling block 3, the first profiling block 3 is removably installed on positioning support 2, so as to
It is replaced according to different welding workpieces；Second profiling block 4 is located between the first profiling block 3 and the first clamping limb 5, and second
Profiling block 4 is provided with the limited location shoulder 4-1 for supporting workpiece, is additionally provided between the second profiling block 4 and the first profiling block 3
Pad 9, places the pad 9 of different-thickness, can adjust the position of the second profiling block 4.
As shown in figure 3, during work, it would be desirable to which the sheet metal component 10 of the frame assembly of welding inserts the first clamping limb 5 and first
Between the clamping limb 7 of profiling block 3. and second and the second profiling block 4, clamping screw 6, locking are screwed in the direction of the second profiling block 4
After sheet metal component 10, you can proceed by weld job, in welding process, the restriction effect of profiling block, it is to avoid the heat of sheet metal component 10
Swollen shrinkage deformation.
