The utility model discloses a kind of wear-resistant PCB board selection
welding jigs, comprising: substrate, its corner is equipped with
assembly slot;Wear plate, its split positioning is on
assembly slot;Bump, its positioning is at the bottom of wear plate, it is engaged with chain for jig conveying;Guide strip, it is set to the side of wear plate, it is abutted with the side of chain.The utility model's selection
welding jig can greatly slow down the wear rate of corner after jig use, improve its service life, so that the conveying of chain to jig is more stable.Through bump and chain engagement
butt joint, guide strip and chain side abut, to replace the synchronous driving conveying mode of traditional jig by the
friction force of bottom and chain with multi-
surface friction fit structure direct pushing composite
driving mode, to further reduce jig wear, wear plate can be disassembled, replace, to reduce jig use cost, ensure the stability of its conveying.
