Abstract

The invention relates to an automatic straightening machine for a vehicle door assembly, which is characterized in that: a vehicle door positioning and clamping device consists of two movable positioning devices, four fixed positioning devices and six positioning and clamping devices, and is connected with a base through fasteners; the movable positioning devices and the positioning and clamping devices are connected with a pneumatic actuator, namely a cylinder through the fasteners; vehicle door window frame straightening devices are connected with the base of the straightening machine through fasteners, connected with an electrical system actuator, and positioned close to two ends of an upper window frame in the long side size direction; position sensors are arranged at two ends of an upper frame of a vehicle door window frame; and a human-computer interface is connected with a PLC circuit, and signals are input into the PLC which then outputs instructions to a servo drive unit, a servo motor, the human-computer interface, a detector switch and an electromagnetic valve. The automatic straightening machine solves the problem of predeformation of the vehicle door assembly, realizesautomatic straightening in batches, achieves the aim of reducing cost, reduces consumption of labor hours when manufactured by a single trolley and labor intensity of workers, improves productivity,and ensures consistency and reliable quality.

Description

Technical field: [0001] The invention relates to an automatic straightening machine for a car door assembly, which belongs to the technical field of automatic straightening. Background technique: [0002] At present, the door system includes four parts: door opening and closing system, glass lift system, door lock system, and door sealing system. The quality of the door has a great influence on the quality of the vehicle. Car doors are composed of door outer panels, door inner panels, door and window frames, door glass run channels, door hinges, door locks and door and window accessories. During the welding and forming process of the car door assembly, the welding stress causes the door and window frames of the car door to bend and deform to varying degrees, which produces variable stress on the car door assembly. [0003] The previous door correction technology relied on the door welding fixture to pre-deform the positioning and clamping of each welding process single pie...
