Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0021] figure 1 It is a structural schematic diagram of an embodiment of the robot grinding system based on force feedback of the present invention. Such as figure 1 As shown, the system is used for grinding a workpiece 7, and the system includes a robot 1, a workpiece contour detection unit 2, an electric spindle unit 3, a grinding wheel wear detection unit 4, a grinding force detection unit 5 and a system control host 6.

[0022] Wherein, the robot 1 is used for installing the electric spindle unit 3 and controlling the electric spindle unit 3 to perform translation so as to reach a predetermined position for grinding the workpiece 7 . The robot 1 may adopt an existing robot, such as the robot IRB4400 of ABB Company. ...

Abstract

The invention discloses and relates to a robot grinding system based on feedback of a sensor. The robot grinding system based on the feedback of the sensor is capable of detecting an contour of a workpiece and regulating grinding tracks in real time and comprises a robot (1), a workpiece contour detection unit (2), an electro-spindle unit (3), a grinding wheel wear detection unit (4), a grinding force detection unit (5) and a system control host (6). The robot grinding system based on the feedback of the sensor achieves automatic grinding on workpiece surface by detecting the grinding force between a grinding wheel and a workpiece, the three-dimensional measuring data of the outline of the workpiece and wear degree of the grinding wheel and controlling feed speed and rotating speed of the grinding wheel through a control algorithm.

Description

technical field [0001] The invention relates to a robot grinding system for grinding workpieces, belonging to the field of robot grinding. Background technique [0002] Grinding has a wide range of applications, and the quality of grinding often determines the final quality of the product. With the wide application of materials such as special low-carbon steel, aluminum alloy or nickel alloy in aerospace, national defense, electric power, ships and other fields, such as aeroengines, large steam turbines, gas turbines, ship propellers, wind turbine blades, etc. The manufacture of the above materials puts challenging requirements on the grinding and polishing technology. [0003] The traditional grinding of large workpieces mainly includes manual grinding, special machine tool grinding and CNC machine tool grinding. The manual grinding method has a large workload and low efficiency, and the quality of workpiece processing cannot be guaranteed; special machine tools are not v...
