Floating positioning module

Abstract

The invention discloses a floating positioning module. The floating positioning module comprises a cover plate, a positioning block, a shell body and a connection plate, wherein the cover plate, the positioning block, the shell body and the connection plate are arranged in a stack-up manner in sequence. The cover plate is fixedly connected with the positioning block, the positioning block is fixedly connected with the shell body, and a first storage space is enclosed by the positioning block, the shell body and the connection plate. The first storage space is internally provided with a floating block, a floating gap is reserved between the floating block and the shell body in the periphery direction of the floating block, and the floating block is fixedly connected with the connection plate. The floating positioning module further comprises a locking mechanism so that the relative position between the floating block and the shell body can be fixed or the floating block can float relative to the shell body. The floating positioning module is high in bearing capacity; the locking mechanism is arranged, shaking and vibration of objects in the movement and carrying processes are avoided, and no noise is generated; meanwhile, the stability of a mechanical arm is improved, the service life of the mechanical arm is prolonged, and the maintenance cost is lowered; angular floating is added based on planar floating, and thus tool damage and damage to the positioning faces of the objects caused by inaccurate positioning are avoided; and meanwhile, damage, caused by horizontal and angular stress in the workpiece grabbing process, of the mechanical arm is lowered.

Description

technical field [0001] The invention relates to the technical field of automatic loading, unloading and handling equipment, in particular to a floating positioning module. Background technique [0002] With the continuous promotion of automation technology, the market has higher and higher requirements for automation equipment, especially for automatic loading, unloading and handling equipment, most of them require manipulators to be able to position accurately, especially when handling objects that require accurate positioning. , such as: the object to be transported requires two pin positioning, etc., not only requires accurate plane positioning, but also accurate angular positioning. However, since the movement of the manipulator has precision errors, it cannot meet the requirements. If the movement of the seventh axis of the manipulator is added, the error will increase. Larger, resulting in failure to meet positioning requirements during loading, unloading or handling o...

Problems solved by technology

[0005] 1. Due to the wrong use of the load-bearing direction of the guide rail and slider, the load-bearing capacity is poor;

[0006] 2. Since there is no locking mechanism, during the movement of the manipulator, the object drives the slider to shake, and the resulting collision can easily damage the slider, which increases maintenance costs. At the same time, the moving collision noise is large, and the shaking caused by the movement reduces the manipulator. stability and service life;

[0007] 3. Although the floating in the horizontal direction is satisfied, it cannot satisfy the floating and correction of the upward angle. When the object to be carried needs two pins to be positioned, it cannot float in the angular direction, which will cause jamming, damage the connecting pin of the object or the connection on the object hole, and the slider on the floating positioning structure is also easily damaged
