As shown in FIGS. 1-2; a feeding device of a welding machine comprises: frame 1, base 3. A beam of the frame 1 is provided with a spot welding rod 2, and the spot welding rod 2 can slide up and down on the beam in a reciprocating manner through a vertical sliding rail mechanism;
a supporting plate 5 fixedly connected with the frame 1 is arranged below the cross beam, the supporting plate 5 is connected with the spot welding rod 2 in a sliding manner, and an incomplete gear 51 is rotatably connected to the base 3;
one end of a linkage rod 6 is hinged on the spot welding rod 2, the other end of the linkage rod 6 is hinged with a connecting rod 53 on the end face of the incomplete gear 51, and the incomplete gear 51 is driven to rotate by the up-and-down reciprocating sliding of the spot welding rod 2;
the base 3 is connected with a material conveying platform 4 in a sliding way, and the material conveying platform 4 is horizontally provided with a pair of racks 41 which can be meshed with the incomplete gear 51;
the racks 41 are symmetrically arranged above and below the incomplete gear 51;
the rotation of the incomplete gear 51 can drive the rack 41 to horizontally slide back and forth;
the incomplete gear 51 is located below the middle position of the spot welding rod 2.
Specifically, fixed connection backup pad 5 on frame 1, the top of backup pad 5 is equipped with the through-hole for cup joint on the upper portion of spot welding pole 2, guarantees that the up-and-down motion of spot welding pole 2 is more steady. The spot welding rod 2 reciprocates up and down by a lifting mechanism, which is common knowledge in the art and will not be described herein. The lower part of the spot welding rod 2 is hinged with the linkage rod 6 which is horizontally placed, the incomplete gear 51 is also vertically fixed with a horizontal connecting rod 53, and the spot welding rod 2, the linkage rod 6, the connecting rod 53 and the incomplete gear 51 form a crank-link mechanism.
The material conveying platform 4 and the base 3 slide through horizontal slide rails, and the number of the slide rails is at least two. The material conveying platform is preferably a hollow cuboid structure which is penetrated in the front and back direction, the top surface of the material conveying platform is provided with a plane for spot welding operation, and the upper surface and the lower surface of the hollow inner part of the material conveying platform are oppositely provided with a rack 41 which is meshed with the incomplete gear 51.
