The invention discloses a static restraint shoulder
drill chuck
welding tool and a friction static restraint column implanting method, relates to a CGA device column implanting
welding tool and method, and aims at solving the problems that according to an existing mold-free column implanting method, the holding force between a
welding ball and a welding column is low, the welding ball and the welding column are likely to peel off, and the metallurgical effect is insufficient. The welding tool comprises a
drill chuck movement transmission mechanism, a
drill chuck clamping
assembly and a static pressure restraining mechanism, and the static pressure restraining mechanism and parts are fixed through a left side fixing plate with holes and a right side fixing plate with holes, wherein the left side fixing plate and the right side fixing plate are integrated with a drilling
machine spindle bearing cover. The method comprises the following steps: 1, manufacturing array spherical-crown-shaped
brazing filler metal solder balls; 2, determining the
diameter and depth of a static pressure restraint shoulder welding column containing through hole; 3, determining the sizes of a spherical-crown-shaped pressurizing working surface and a horizontal shaft
shoulder surface; 4, determining the length of the part, exposed out of a clamping jaw of a drill chuck, of the welding column; 5, determining the minimum
assembly distance between the clamping jaw of the drill chuck and a static pressure restraint shoulder; and 6, rotating an operating
handle to apply static restraint to perform friction static restraint column implanting on the single and array to-be-implanted welding columns. The static restraint shoulder drill chuck welding tool and the friction static restraint column implanting method are used for column implanting of a CGA device.
