Slide 23 is retracted to initial position, and completion is once welded.
Step 8: being placed again into magnetic conduction bar in locating slot 34, motor 11, which is rotated, once makes stator casing second to be welded
Connect position to be in topmost, then repeat step three, four, five, six, seven.
Step 9: process in repeat step eight, until welding is completed, removes stator casing；Due to being positioned in welding process
Block 33 is not contacted with stator casing, will not be welded and is connected to together, thus can directly extract the stator casing being welded out.
It should be noted that during with a batch of welding processing, because process is identical, thus without entering again
Setting work in row step one, multiple operation sequences can be set in the controls in practical operation, for containing different
The stator casing of number magnetic conduction bar can directly enter line program selection.
The welding method of the present invention, by mutual between drive mechanism, welding mechanism, propulsion positioning mechanism and hold-down mechanism
Coordinate to be automatically performed the welding processing of stator casing, reduce labor strength, and accurate positioning, welding effect is good,
Substantially increase the welding processing quality and processing efficiency of stator casing.
Schematical above that the present invention and embodiments thereof are described, the description does not have restricted, institute in accompanying drawing
What is shown is also one of embodiments of the present invention, and actual structure is not limited thereto.So, if the common skill of this area
Art personnel are enlightened by it, without departing from the spirit of the invention, are designed and the technical scheme without creative
Similar frame mode and embodiment, all should belong to protection scope of the present invention.
