Hemming device for wheel housing of vehicle

Abstract

The present invention provides a hemming device for a wheel housing of a vehicle where a hemming bed unit is attached to an installation frame at one side of the wheel housing, and where a worker can manually hem an inner panel and an outer panel by rotating a hemming roller unit for each process of which the lower portion is fixed to the upper center of the installation frame by a rotary clamper. The hemming device includes an installation frame that is formed by support beams supported by dampers at both sides on an installation plate with casters thereunder and an installation beam disposed at the center on the installation plate; and a hemming bed unit, where the hemming bed is fixed to the upper ends of the support beams on the installation frame. The wheel housing is supported by attaching the hemming bed to the outer surface of the outer panel of the wheel housing of the vehicle body. Also included are bed fixing members disposed at both sides of the installation beam of the installation frame, where the hemming bed is fixed to the outer panel of the wheel housing; and a hemming roller unit mounted to the upper end of the installation beam of the installation frame by a rotary clamper and hemming the outer panel with respect to the inner panel of the wheel housing by manually rotating two hemming rollers.

Description

technical field [0001] The invention relates to a hemming device for a wheel cover of a vehicle. More particularly, the present invention relates to a hemming device for a vehicle wheel well that is attached to one side of the vehicle body wheel well to enable a worker to manually hem inner and outer panels. Background technique [0002] When building a vehicle, automakers assemble 20,000 to 30,000 parts multiple times. [0003] The manufacture of the vehicle body is the first step in the vehicle manufacturing process. Typically, a body in white (B.I.W) is manufactured by producing the product panels by various pressing machines, transporting the product panels to the body factory, and then assembling the components of the product panels. [0004] To form such a panel, a forming process of press-forming the panel into a predetermined shape by various pressing machines is used, followed by cutting, hole forming, bending and bending in pressing processes such as trimming, pun...

AI Technical Summary

Problems solved by technology

[0008] When due to some reasons, such as when the manipulator fails, fatigue failure, friction and problems with the components of the roller hemming, damage to the system due to the stoppage of the worker's wrong operation on the production line, and wrong changes to the electrical program of the hemming, the When the production line stops, the current robotic roller hemming engineering method for the rear wheel housing of the car body takes a long time to return to normal

As a result, productivity decreases and economic loss results
