The welding and positioning jig for the pneumatic spring handle shown in fig. 1 comprises a jig substrate 100, a first limiting enclosing plate 200 and a second limiting enclosing plate 300, the first and second limiting enclosing

plates

200 and 300 are fixed on the jig substrate 100, the first retaining fence 200 includes a front retaining plate 220, a left retaining plate 230 and a rear retaining plate 240, the front limiting plate 220 and the rear limiting plate 240 are parallel and both ends of the left limiting plate 230 are respectively vertically connected with the left end of the front limiting plate 220 and the left end of the rear limiting plate 240, the front and rear distances of the front and

rear stoppers

220 and 240 are the same as the front and rear widths of the one end U-bent metal handle to be welded, the front and back width of the inner periphery of the second limiting coaming 300 is the same as the front and back width of the welded lower block of the right-angle combined metal block, the first limiting enclosing plate 200 and the second limiting enclosing plate 300 are respectively provided with a first pressing device 210 and a second pressing device 310 which are used for aligning and pressing the metal handle and the right-angle combined metal block. Put right angle combination metal block counterpoint on the inner wall breach of second spacing bounding wall 300 and remove the breach rightmost before the welding, rethread second collet 310 compresses tightly right angle combination metal block, then place metal handle counterpoint between preceding limiting plate 220 and back limiting plate 240, move metal handle right and remove the welding point contact of welded cylinder end and right angle combination metal block, rethread first collet 210 compresses tightly metal handle and can carry out welding operation. The welded metal handle and the right-angle combined metal block are accurately aligned and fixed, so that the welding operation difficulty is reduced, and the yield is improved.
