Turning lifting appliance suitable for two models of parts

Abstract

The invention discloses a turning lifting appliance suitable for two models of parts. The lifting appliance comprises a frame body, wherein the frame body is connected with a first vertical beam and a second vertical beam; symmetrical turning mechanisms are arranged at the lower ends of the first vertical beam and the second vertical beam; each turning mechanism is provided with symmetrical grippers for clamping a workpiece; one turning mechanism is provided with a turning limit piece; the first vertical beam is connected with the frame body in a sliding mode; a manual limit shaft is arranged on the first vertical beam; the upper end of the limit shaft is matched with limit supports; the limit supports are fixedly arranged relative to the frame body; two limit supports are arranged separately; and the second vertical beam is fixedly connected with frame body. The lifting appliance has a simple structure, switches models conveniently, is easy to operate, and is suitable for various models; and the lifting appliance is not required to be replaced when the models are switched, so that the processing cost and tooling cost of the workpiece are reduced, work efficiency is improved, and the labor intensity of operating personnel is reduced.

Description

technical field [0001] The invention relates to an overturning sling suitable for parts of two types of vehicles, which is mainly used in the manual welding area during the welding process of automobile body-in-white, and can lift and overturn the welded workpieces of the two types of vehicles respectively. Background technique [0002] With the continuous development of the automobile industry, major automobile manufacturers have shortened the production cycle and increased the output of models with considerable sales volume, so sometimes two or more models with similar appearances need to be produced on the same line, making the structure of automobile welding tools It is also constantly improving, and various complex and large-scale tooling are also emerging. However, the collinear production of the car models made the turning spreader of a car model used in the manual welding area unable to meet the needs of production and transportation in the workshop, because although...

Problems solved by technology

However, the collinear production of the car models made the turning spreader of a car model used in the manual welding area unable to meet the needs of production and transportation in the workshop, because although the two car models are similar, the specific dimensions of the cars, especially the length dimensions, will not be exactly the same , if you use the original type of spreader, you need at least two spreaders, because each model needs to be equipped with a spreader, which not only occupies the operating space, but also increases the input of manpower and material resources, resulting in production efficiency. reduce

The existing overturning spreader structure for hoisting a vehicle type is that there is a frame body with a suspension ring on the top, and two vertical vertical beams parallel to each other are fixedly connected below the frame body, and at the lower end of each vertical beam An overturning mechanism is installed, and each overturning mechanism is equipped with symmetrical grippers for clamping workpieces, forming four grippers arranged symmetrically with each other, and one overturning mechanism is provided with overturning limiters, two of which The distance between the vertical beams is fixed and cannot be changed, which can only meet the needs of one type of vehicle
