This invention discloses a welding fixture and method for transition elbows, including a welding platform and a positioning component. The positioning component is set on the welding platform and includes a clamping device, a clamping device, a support block, and a positioning block. The positioning block has a rectangular structure. One end of the clamping device is set on the welding platform, and the other end of the clamping device is located above the lowest positioning platform. The two clamping ends of the clamping device are located on both sides of the lowest positioning platform. This application achieves simultaneous fixing of plate 1, plate 2, plate 3, and plate 4 by coordinating the welding platform and the positioning component, thereby realizing a one-time welding forming operation, ensuring welding stability and welding accuracy, improving work efficiency, and ensuring the quality of the transition elbow.

The application discloses a kind of displacement-resistant patch devices for SMT chip mounter, specifically relates to SMT chip mounter technical field, including conveying belt, fixedly installed in the top surface of conveying belt chip mounter, fixedly installed in the operation panel of chip mounter front, two front and rear symmetrical clamps in the upper of conveying belt.It is synchronous translation by motor drive double-end threaded rod to drive both sides slider and clamp through displacement-resistant component, cooperate with the guidance of first slide rod, let clamp be stable to the patch and draw close, realize the close gapless clamping of patch front and rear side, eliminate horizontal direction displacement;Clamping simultaneously, patch extrusion push plate triggers gas transmission structure, promotes second slide rod and drives pressure plate to descend, so that rubber plate forms flexible extrusion to patch top surface, spring can be adapted to different thickness patch, realize non-injury pressure solid, form the double fixing effect of front and rear clamping+top surface pressure solid, avoid patch to appear deviation, warping etc. in the process of mounting, guarantee mounting precision.
