Turning course:
The major function of workpiece revolution positioner 1 is to realize workpiece turning positioner 5 and turn around mounted in workpiece thereon
Positioner 4, fixture assembly 3 are turned round, and then drive workpiece revolution.Rotary disk 105 is driven to rotate by first rotating shaft 101,
Rotary disk 105 drives L shaped plate 106 to rotate, so that workpiece be driven to carry out revolution displacement.
Switching process:
The major function of workpiece turning positioner 5 is to realize that workpiece turns around the tumbling of positioner 4 and fixture assembly 3, in turn
Realize tumbling for workpiece.The rotation of the second shaft 503 is driven by the second motor 504, positioner 4 and fixture are total so that workpiece turns around
Overturning movement is done at 3, realizes tumbling for workpiece.
It turns around to conjugate:
The turn around effect of positioner 4 of workpiece is to realize the transformation of the location of workpiece after the completion of the 45 ° of welding in workpiece one end, with
Convenient for the welding of 45 ° of bend pipes of the other end.Third motor 405 is driven, third worm speed reducer 404 is driven to rotate, is turned by third
Axis 402 drives the rotation of turntable 401 of turning around, and 180 ° of rotation is realized, so that the location of workpiece be made to convert.
Workpiece is tumbled while revolution, guarantees that the pad of welding gun is constantly in horizontal position, and welding gun is in order to allow
It opens elbow internal wall to rotate together also with workpiece, rifle point is motionless while rotation, completes the heap postwelding of single-ended 45 ° of bend pipes, welding gun
It returns to outside workpiece.The built-up welding operation that 45 ° of bend pipes of other side are realized after displacement, realizes that 90 ° of elbow internal wall entirety heaps are welded into
Type.
The process for carrying out 90 elbow internal wall built-up welding welding using the present invention is as follows:
Step 1 adjusts Y-axis guide rail 313 and positions the specific location of slide 307 according to workpiece concrete shape and size,
Workpiece is packed into fixture assembly 3, and workpiece is compressed;
Step 2 drives the second motor 504 in workpiece turning positioner 5, so that tipping pitman is driven, by the single-ended of workpiece
It tumbles to horizontal position, positioner 1 is turned round by workpiece and realizes workpiece itself revolution, starts the motor for starting welding robot 6
Built-up welding is carried out to the straight-tube portion of bend pipe;
Step 3 then carries out first 45 ° of bend pipe built-up welding when the straight-tube portion heap of bend pipe is soldered;Workpiece turning positioner 5
Synchronous working, workpiece are tumbled while revolution, guarantee that pad is constantly in horizontal position, in welding robot 6
Welding gun rotates together to get out of the way elbow internal wall also with workpiece, and rifle point is motionless while rotation;
After heap is welded into single-ended 45 ° of bend pipes, welding gun is returned to outside workpiece for step 4;
Step 5 is resetted workpiece using workpiece turning positioner 5, and the positioner that turns around turns round reality by the turntable 401 that turns around
Existing location of workpiece transformation, prepares the welding of the bend pipe other end;
Step 6 repeats the built-up welding that step 2 realizes the other one end of bend pipe to these steps of step 4.
Step 7 is resetted workpiece using workpiece turning positioner 5, and entire 90 ° of bend pipe built-up welding are completed.
The invention patent for 90 ° of elbow internal wall built-up welding displacement devices design a kind of output torque sufficiently, can be with welding
Robot 6 does coordination and realizes that the three axis positioners of 90 ° of elbow internal wall built-up welding and XY axial adjustment realize the straight, curved of different-diameter
Pipe transformation has high accuracy positioning clamping tool.Entire weld deposit process realizes the continuous productive process of welding, can sufficiently reduce
Operator's labor intensity sufficiently improves working efficiency.
