Double-face polishing arm device for polishing propeller of large-sized ship

Abstract

The invention belongs to the field of manufacturing industry polishing and machining, and particularly relates to a double-face polishing robot arm device for polishing a propeller blade of a large-sized ship. The double-face polishing arm device comprises a power module, and two sets of polishing components which are arranged symmetrically. Each set of polishing component comprises a belt transmission module, a polishing head telescopic mechanism module and a self-adaption polishing head module. The double-face polishing device can achieve corresponding and simultaneous polishing of two side positions in the polishing process of the propeller blade of the large-sized ship, so that the vibration when the edge of the blade of the propeller is polished is reduced effectively. By adoption of a self-adoption attaching mechanism, rapid response to change of the surface shape of a workpiece can be made, and the working period of a polishing robot is shortened; and compared with single-face polishing, the double-face polishing arm device improves the polishing efficiency.

Description

technical field [0001] The invention belongs to the field of manufacturing grinding and processing, and in particular relates to a double-sided grinding robot arm device for grinding large-scale marine propeller blades. Background technique [0002] With the advancement of shipbuilding technology and the development of large-scale and high-speed ships, the size of marine propellers is getting larger and higher, and the speed is getting higher and higher. high demands. For a long time, most of the grinding of large and large marine propeller blades has been done manually, but the surface quality of manually polished blades is generally poor and the blade surface consistency is low. In addition, workers who have been engaged in manual grinding for a long time will also affect their health due to inhaling too much dust. [0003] With the development of modern production and science and technology, the manufacturing industry puts forward higher and higher requirements for auto...

Patent CN204366659U, patent CN104511815A, and patent CN205600476U are all ideas for double-sided grinding. The basic principle is to use the method of simultaneously grinding corresponding positions on both sides of the workpiece to reduce the vibration during grinding, but the device structure of these three inventions is simple. It is only suitable for simple flat double-sided grinding, and it is difficult to complete double-sided grinding of complex surface workpieces
