Problems solved by technology

The assembly sequence is the fixed assembly on the front seat belt slide → the body of the B-pillar inner panel → the front retractor installation plate. The current production mode of the assembly mainly has the following problems: the fixed assembly on the front seat belt slide is replaced by the B-pillar The inner plate is covered by the main body. When the seat belt slide plate is missing welded nuts, it cannot be visually inspected normally and flows into the subsequent process. Only when the retractor high-profile device is assembled in the final assembly and it is found that it cannot be tightened can the nuts be leaked welded. At this time, the production line is blocked. Sudden interruption, the whole vehicle is scrapped or downgraded, resulting in relatively large economic losses

Abstract

The invention provides a projection welding nut leakage resistance and positioning welding mechanism. With the projection welding nut leakage resistance and positioning welding mechanism, the problemsabout positioning and leakage resistance of projection welding nuts can be solved at the same time. The projection welding nut leakage resistance and positioning welding mechanism comprises a base. Aguide rod mechanism is arranged beside the base. A positioning guide mechanism is arranged above the guide rod mechanism. The positioning guide mechanism comprises a positioning guide block and a positioning pilot pin. The upper surface of the positioning guide block is a profile conforming face of an assembly part used for being attached to an installation nut. The upper end of the positioning pilot pin is connected with the positioning guide block and penetrates through the profile conforming face. The part, penetrating out of the profile conforming face, of the positioning pilot pin is provided with a circular-truncated-cone-shaped positioning portion with the reducing diameter. An inclined face with an adjustable inclination angle is arranged at the bottom of the lower end of the positioning pilot pin. A guide rod on the upper part of the guide rod mechanism is provided with a connecting plate. A mechanical valve is arranged beside the connecting plate. The mechanical valve is arranged below the inclined face. A positioning stop dog is arranged beside the connecting plate. A shape conforming positioning stop dog used in cooperation with the positioning stop dog in the travel of the guide rod mechanism is arranged on the base.

Description

technical field [0001] The invention relates to the technical field of auxiliary equipment for automobile production, in particular to a projection welding nut leakage prevention and positioning welding mechanism. Background technique [0002] In the general car body welding process, the B-pillar inner panel body assembly, the front safety belt slide plate fixing assembly, and the front retractor mounting plate are welded together to form the B-pillar inner panel assembly. The assembly sequence is the fixed assembly on the front seat belt slide → the body of the B-pillar inner panel → the front retractor installation plate. The current production mode of the assembly mainly has the following problems: the fixed assembly on the front seat belt slide is replaced by the B-pillar The inner plate is covered by the main body. When the seat belt slide plate is missing welded nuts, it cannot be visually inspected normally and flows into the subsequent process. Only when the retracto...
