Windmill flexible positioning device for white car body welding production line

Abstract

The invention discloses a windmill flexible positioning device for a white car body welding production line. The windmill flexible positioning device for the white car body welding production line comprises a rotary table rack, wherein a vertically arranged and rotatable windmill rotary plate is arranged on one side of the rotary table rack; a drive device for driving the windmill rotary plate torotate is arranged on the rotary table rack; multiple positioning stations arranged uniformly are arranged on a plate body of the windmill rotary plate; detachable positioning mechanisms for clampingworkpieces are arranged on the positioning stations; a station switching mechanism for controlling a rotation position of the windmill rotary plate is arranged between the windmill rotary plate and the rotary table rack; and an automatic emergency stop mechanism is arranged between the rotary table rack and the windmill rotary plate. The windmill flexible positioning device for the white car bodywelding production line provided by the invention is simple in structure, easy to maintain, low in cost, easy to control, good in universality, and capable of being adaptable to flexible positioning of multiple platform multi-car switching.

Description

technical field [0001] The invention relates to the flexible production field of automatic welding of automobiles, more specifically, it relates to a windmill flexible positioning device used in a body-in-white welding production line. Background technique [0002] At present, the development trend of the world's automobiles is from mass production to multi-variety and small-batch production. In order to meet the extensive and diverse needs of automobile consumers and adapt to the fierce competition in the automobile market, major automobile manufacturers in the world continue to shorten the model change In order to adapt to this development trend, the body-in-white flexible welding production line that can produce multiple models in one production line has been widely adopted by major automobile companies. [0003] The key technology of the flexible body-in-white welding production line is positioning and clamping of different models. The traditional positioning method is f...

Problems solved by technology

[0003] The key technology of the flexible body-in-white welding production line is positioning and clamping of different models. The traditional positioning method is fixed, and the positioning holes of the body are positioned through the positioning mechanism fixed on the bottom plate, but the size of the positioning holes of this mechanism is fixed. , can only be applied to a single model platform with the same positioning hole size, the change of the next model needs to accommodate the position and size of the positioning hole, which is not conducive to the diversification of vehicle models

[0004] Now the most used positioning method is the switchable flexible positioning method. The multi-axis servo flexible positioning unit is used to position the vehicle body and its parts flexibly. This method has many types of vehicle platforms and can be positioned theoretically within the travel range. Vehicles with any size and position, but the multi-axis servo flexible positioning unit has complex structure, difficult control, high cost, difficult maintenance, and the diameter of the positioning hole for the vehicle body cannot be changed, so it cannot correspond to the production of multiple models with different apertures
