Abstract

The invention discloses a welding fixture for reinforcing ribs of a knee guard bar. The welding fixture comprises a base. Two grooves are formed in the upper surface of the base, wherein the two grooves correspond to through holes of the reinforcing ribs of the knee guar bar respectively. A first direction positioning block and second direction positioning blocks are arranged inside each groove, the first direction positioning blocks which are arranged in the two grooves respectively are locked through locking bolts and are used for positioning the reinforcing ribs of the knee guard bar in the first direction, at least two second direction positioning blocks are arranged in each groove, and the second direction positioning blocks which are arranged in the two grooves respectively are locked through locking bolts and are used for positioning the reinforcing ribs of the knee guard bar in the second direction. The welding fixture for the reinforcing ribs of the knee guard bar has the advantages that welding error is small when through holes are used for positioning, further, the locating reference can be adjusted so that the reference can be adjusted effectively after the reference is worn, and cost is reduced.

Description

technical field [0001] The invention relates to a tooling fixture, which belongs to the technical field of mechanical processing. Background technique [0002] The knee protection bar is a part of the car bumper, which is a safety device that absorbs and moderates external impact and protects the front and rear of the car body. The process of producing the knee protection bar includes a step of welding the reinforcing rib. Such as figure 1 As shown, the reinforcing rib 10 is a thin sheet. The rib 10 includes two through holes 11 . In the existing welding process, the short side 12 of the reinforcing rib 10 is the positioning side, and the long side 13 is the welding side. Since the short side 12 used as the positioning reference is also stamped and has burrs, when this is used as the positioning reference, the welding error is relatively large. Contents of the invention [0003] In view of the above-mentioned defects in the prior art, the object of the present inventi...
