Abstract

Present invention provides a handy tool that can be used to facilitate welding job, where (second) work objects can be held on by the holding surfaces of the first positioning frame of the welding bracket; the first positioning frame is used to hold on to another (first) work piece between the generally v-shaped swinging foot pieces on the v-frame; the two swinging foot pieces can pivot on respective axle, allowing for adjustment to different size/diameter of first work piece, and the bolt and butterfly nut structure allows adjustment to be made between first positioning piece and the v-frame, for purpose of adapting to welding object of different thickness held on by the holding surfaces on the positioning frame.

Claims

1. A tab welding bracket, comprising a positioning frame used to hold on or attach to work pieces, said positioning frame further having guide ear pieces for slidably engaging and limiting the relative travel to a v-frame which further comprising a base and two swinging foot pieces affixed to respective swing axles at two ends of said base whereby said two swinging foot pieces generally form a v-angle as defined by the foot surfaces of said swinging foot pieces.

2. The tab welding bracket of claim one, wherein said positioning frame has a generally flat base plate with two holding surfaces formed on the two ends of said base plate wherein said two holding surfaces are folded in a 90-degree fashion to the surface of base plate.

3. The tab welding bracket of claim two, wherein said two holding surfaces are oriented at a 90-degree fashion relative to each other, in addition to being at a 90-degree angle to the flat base plate of said positioning frame.

4. The tab welding bracket of claim one, wherein the two holding surfaces formed on the two ends of said base plate may have angles of 30, 45 or 60 degrees relative to the surface of said base plate, as desired by specific implementations.

5. The tab welding bracket of claim one, wherein the sliding and limiting-travel arrangement between said positioning frame and v-frame are provided by a slot on said positioning frame, a butterfly nut and a bolt, so that users can fix the position of said holding surface, according to the thickness of the work piece being attached to said holding surface.

6. The tab welding bracket of claim one, further having clamping extenders made to the outer ends of said holding surfaces, so that additional clamping devices can be used when non-magnetic adhesion is needed to hold/align work pieces.

7. The tab welding bracket of claim one, further having two saddle spring pieces on each of the swing axel, providing some resisting damping effect to the pivoting action of each swinging foot piece.

8. The tab welding bracket of claim one, wherein each of said holding surface contains one or more magnetic pieces for purpose of holding on or securing to work objects that have magnetic workability.

9. The tab welding bracket of claim one, wherein each of said foot surface of said swinging foot contains one or more foot magnets for purpose of holding on or securing to work objects that have magnetic workability.
