Special wheel cake loading and unloading robot for automatic production line

Abstract

The invention belongs to the technical field of handling equipment and relates to a special wheel cake loading and unloading robot for an automatic production line. A rotating arm of the robot is connected with a machine body through a gear pair and is connected with paws through guide pillars; a rotating servo motor is connected with the rotating arm through the gear pair and drives the rotating arm to rotate, and a paw lifting oil cylinder is connected with the paws through a steel wire rope; the steel wire rope changes in direction twice through a pulley block so as to drive the paws to ascend and descend; a paw opening and closing oil cylinder drives the paws to open and close through a connecting rod group so as to clamp a wheel cake workpiece; and a rotating flashing light is fixed on the rotating arm through a screw. The special wheel cake loading and unloading robot has the advantages of being high in repeated positioning accuracy, more accurate and stable in running, higher in rotating speed and easier to control, reaching a max rotating angel speed of 0.25rad / s, reducing power dissipation substantially, and having a stable clamping effect and a self-locking function.

Description

technical field [0001] The invention belongs to the technical field of handling equipment, and relates to a special loading and unloading robot for wheel cakes on an automatic production line. Background technique [0002] In today's my country's railway vehicle manufacturing industry, for many years, the method of transporting wheel cakes with a mass greater than 300kg has been used for many years, and it is extremely inconvenient to enter and exit the processing center. In recent years, with the development of modern manufacturing industry, various enterprises are scrambling to set up automated production lines. Some factories have also begun to import foreign advanced logistics handling systems, such as Cartesian coordinate robots and joint robots. Due to the performance limitations of components, the design lifting weight or slewing speed cannot be achieved. Contents of the invention [0003] The technical solution of the present invention is to overcome the disadvant...
