Turning course:
The major function of workpiece revolution positioner 1 is to realize workpiece turning positioner 5 and turned 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 as to drive workpiece 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, and then
Realize tumbling for workpiece.By the second motor 504 drive the second rotating shaft 503 rotate so that workpiece turn around positioner 4 and fixture it is total
Overturning movement is done into 3, tumbling for workpiece is realized.
Turn around to conjugate:
The turn around effect of positioner 4 of workpiece is after the completion of the welding of 45 ° of workpiece one end, to realize the conversion of the location of workpiece, with
It is easy to the welding of 45 ° of bend pipes of the other end.The 3rd motor 405 is driven, drives the 3rd worm speed reducer 404 to rotate, passes through the 3rd turn
Axle 402 drives the rotating disk 401 that turns around to rotate, and 180 ° of rotation is realized, so that the location of workpiece is converted.
Workpiece is tumbled while revolution, it is ensured that the pad of welding gun is constantly in horizontal level, and welding gun is in order to allow
Open elbow internal wall to rotate together also with workpiece, rifle point is motionless while rotation, complete the heap postwelding of single-ended 45 ° of bend pipes, welding gun
Return to outside workpiece.The built-up welding operation of 45 ° of bend pipes of other side is realized after displacement, realizes that the overall heap of 90 ° of elbow internal walls is welded into
Type.
The process for carrying out 90 elbow internal wall built-up welding welding using the present invention is as follows:
Step one, according to workpiece concrete shape and size, the particular location of adjustment Y-axis guide rail 313 and positioning slide 307,
Workpiece is loaded into fixture assembly 3, and workpiece is compressed;
The second motor 504 in step 2, driving workpiece turning positioner 5, so that tipping pitman is driven, by the single-ended of workpiece
Tumble to horizontal level, positioner 1 is turned round by workpiece and realizes that workpiece itself is turned round, starts to start the motor of welding robot 6
Built-up welding is carried out to the straight-tube portion of bend pipe;
Step 3, when the straight-tube portion heap of bend pipe is soldered, then carries out first 45 ° of bend pipe built-up welding;Workpiece turning positioner 5
Synchronous working, workpiece is tumbled while revolution, it is ensured that pad is constantly in horizontal level, welding robot 6
Welding gun is rotated together in order to get out of the way elbow internal wall also with workpiece, and rifle point is motionless while rotation;
Step 4, heap is welded into after single-ended 45 ° of bend pipes, and welding gun is returned to outside workpiece;
Step 5, is resetted workpiece using workpiece turning positioner 5, and the positioner that turns around turns round reality by the rotating disk 401 that turns around
Existing location of workpiece conversion, prepares the welding of the bend pipe other end;
Step 6, these steps of repeat step two to step 4 realize the built-up welding of the other one end of bend pipe.
Step 7, is resetted workpiece using workpiece turning positioner 5, and whole 90 ° of bend pipe built-up welding are completed.
Patent of the present invention for 90 ° of elbow internal wall built-up welding displacement devices design a kind of output torques fully, can be with welding
Robot 6 does coordination and realizes that the straight, curved of different-diameter is realized in three axle positioners of 90 ° of elbow internal wall built-up welding and XY axial adjustment
What pipe was converted has high accuracy positioning clamping tool.Whole weld deposit process realizes the continuous productive process of welding, can fully reduce
Operator's labor intensity, fully improve operating efficiency.
