Background

The body in white of an automobile is generally supported by a carrier, such as a skid, a sling, etc., through a fulcrum hole at the bottom of the automobile. The fulcrum hole usually has a standard position, but the fulcrum position of a special vehicle type such as an electric vehicle can be changed, so that the existing carrier fulcrum cannot be directly used.

If a new pivot is added on the carrier only for a new vehicle body pivot hole, the simultaneous production of multiple vehicle types can be influenced, for example, the situation that the pivot of the vehicle type A interferes with the vehicle type B, and the like. Chinese patent application CN107350131A discloses an automatic switching device for positioning pivot of multi-platform coating skid, which can automatically switch the positioning pivot of the skid. But the technical scheme has obvious defects: 1. each pivot is driven by a motor, the cost is huge, a workshop with 1200 vehicle bodies produced in China is taken as an example, 400-450 skids are usually needed, and 400 motors are needed according to the design; 2. the motor can not resist the high temperature of 200 degrees, and can not pass through a drying furnace, so that the application of the motor in a coating workshop is limited; 3. due to the complex structure, when glue is sprayed to the vehicle body bottom plate part, the glue spraying robot is difficult to avoid the mechanism, and certain parts of the vehicle body cannot be automatically sprayed.

Therefore, a position-adjustable fulcrum structure is needed to realize flexible production of various vehicle types, and meanwhile, the robot capable of facilitating subsequent operation can avoid the position-adjustable fulcrum structure, and the cost is low.
