Automatic grounding wire mechanism for main welding wire station

The utility model provides an automatic grounding wire mechanism for a main welding wire station, which comprises a base and a connecting rod hinged on the base, the connecting rod is respectively provided with a first end and a second end at two sides of a hinge point, the second end is elastically connected with the base to keep the first end inclined upwards, and the first end is used as a touch end to be contacted with a body in white. When the body-in-white moves to the first end, the body-in-white contacts with the first end to realize grounding. The grounding wire mechanism can automatically realize grounding operation before welding of the body-in-white, can reduce action waste of operators, and avoids poor lapping and accidental quality problems caused by lapping of the grounding wire. 本实用新型提供了一种主焊线工位自动接地线机构，包括底座和铰接在底座上的连杆，连杆位于铰接点两侧分别具有第一端和第二端，其中第二端与底座弹性相连以保持第一端倾斜向上，所述第一端作为触碰端用于与白车身接触，当白车身移动到第一端时与第一端接触实现接地。该接地线机构可自动实现白车身进行焊接前的接地操作，可以减少操作人员动作浪费，避免在搭地线产生的搭接不良现象及意外质量问题。
