Abstract

The invention discloses a foldable flexible lifting mechanism of a vehicle body correcting machine. The lifting mechanism comprises a rear lower arm, a rear upper arm, a front lower arm, a front upper arm, a parallelogram leveling mechanism, a rear oil cylinder and a front oil cylinder, wherein the rear lower arm and the rear upper arm are hinged with eawch other and have the same length; the front lower arm and the front upper arm are hinged with each other and have the same length; the distance from a hinged point of the leveling rod and the rear upper arm to a hinged point of the leveling rod and a platform is equal to that from the hinged point of the leveling rod and the rear upper arm to a hinged point of the rear upper arm and the platform; the rear oil cylinder and the front oil cylinder have the same working stroke and initial and final setting positions of the working stroke, work at the same speed and drive the platform to lift through a lever arm and front and rear upper support arms. By adopting the arrangement of the foldable support arms, not only can rigid fixed-point vertical lifting be achieved, but also flexible low-position tilt descending can be achieved.

Description

technical field

[0001] The invention relates to a stacked flexible lifting mechanism for an automobile body correction machine.

[0002] The stacked flexible lifting mechanism refers to two functional modes of parallel lifting and tilting lifting, which can perform rigid horizontal lifting when it is greater than or equal to the minimum horizontal height, and can perform flexible tilting lifting when it is less than the minimum horizontal height, and The conversion of the two modes is continuous; the shape and characteristics of the lifting arms are in the form of overlapping or opening during the lifting process. Background technique

[0003] The lifting mechanism is one of the main functional parts of the automobile body correction machine. The lifting mechanism of the automobile body correction machine in the prior art is a parallel four-bar mechanism or a scissor mechanism. The former realizes the lifting of the platform through the swing of the support arm, and its di...
