Problems solved by technology

In mass production, the time required by the offline programming method accounts for a small proportion of the total production time. The offline programming method is suitable for grinding and polishing of the same parts in large batches, but for small batches or single-piece free-form surface grinding and polishing, the offline programming method Disadvantages appear, it is difficult to realize automatic grinding and polishing of robots

Abstract

The invention relates to an automatic free-form surface grinding and polishing system with an industrial robot and a method. The system comprises an upper computer, the industrial robot, a robot controller, a force sensor, a signal collector, a grinding and polishing device and a work table. The upper computer is connected to the signal collector and the robot controller, the robot controller is connected to the industrial robot and the grinding and polishing device, and the signal collector is connected with the force sensor; the industrial robot is connected with the grinding and polishing device, the force sensor is arranged at the connection position of the grinding and polishing device and the industrial robot, and the work table is used for fixing workpieces. The system can directly polish and grind the free surfaces without off-line programming in advance, contact pressure can be constant and adjustable during free-form surface grinding and polishing, and control is simple while operation is easy to perform.

Description

technical field [0001] The invention relates to the field of automatic grinding and polishing of free-form surfaces, in particular to an automatic grinding and polishing system and method for industrial robots of free-form surfaces. Background technique [0002] At present, when grinding and polishing the free-form surface, due to the arbitrariness of the surface, it is difficult to complete the programming of the robot through manual teaching. The pose of the origin of the workpiece coordinate system in the robot coordinate system converts the grinding and polishing path to the robot coordinate system, generates motion commands for the robot, and imports them into the robot controller to realize the grinding and polishing operation of the robot. This method greatly simplifies the process of manual teaching. However, in the process of offline programming, since the coordinate system of the robot and the coordinate system of the workpiece do not coincide, it is necessary to ...
