Shaping positioning tool for welding automobile positioning hook by robot

Abstract

The invention relates to a shaping positioning tool for welding an automobile positioning hook by a robot. A welding seam to be welded is arranged on the positioning hook, the positioning tool comprises a tool bottom plate, a positioning hook positioning mechanism, and a correcting, shaping and compressing mechanism, both the positioning hook positioning mechanism and the correcting, shaping and compressing mechanism are arranged on the tool bottom plate, and the correcting, shaping and compressing mechanism is arranged on the outer side of the positioning hook positioning mechanism. When the positioning hook is welded, the positioning hook is placed on the tool bottom plate through the positioning hook positioning mechanism, the correcting, shaping and compressing mechanism compresses the positioning hook, and the robot welds the welding seam on the positioning hook. Compared with the prior art, the shaping positioning tool has the advantages of simplicity in operation and maintenance, fine error detection performance, high stability and accuracy and the like.

Description

technical field [0001] The invention relates to a processing and positioning device, in particular to a shaping and positioning tool for robot welding of automobile positioning hooks. Background technique [0002] At present, the welding tooling of many automobile positioning hooks has strict requirements on the stamping process of the parts (and the part of the bending position or angle of the stamping part has unstable defects such as the stamping angle is not in place or the rebound is caused by the fluctuation of the positioning), and The existing tooling only plays the role of positioning the parts and has a single function, and has no correction or slight shaping effect on some angles or opening dimensions. Therefore, there must be corresponding special positioning correction and shaping positioning tooling during the welding process, which can further ensure the accuracy of the parts. The stability of the size of the assembly and the matching of this part with other p...

[0002] At present, the welding tooling of many automobile positioning hooks has strict requirements on the stamping process of the parts (and the part of the bending position or angle of the stamping part has unstable defects such as the stamping angle is not in place or the rebound is caused by the fluctuation of the positioning), and The existing tooling only plays the role of positioning the parts and has a single function, and has no correction or slight shaping effect on some angles or opening dimensions. Therefore, there must be corresponding special positioning correction and shaping positioning tooling during the welding process, which can further ensure the accuracy of the parts. The stability of the size of the assembly and the matching of this part with other parts during the loading process also reduce the precision requirements for the stamping die and make up for the defects caused by it

[0003] The existing parts welding tooling has strict requirements on the size of parts stamping parts (because the robot has strict requirements on the position accuracy of the weld seam), it only plays the role of pressing and positioning, and has the disadvantages of relatively complex structure.
