Description
Technical Field
The invention discloses a terminal hole making actuator, particularly relates to a terminal hole making actuator for lamination assembly of airplane body components, and belongs to the field of automatic hole making of airplane digital assembly.
Background
efficient and precise hole making for laminated assembly of a machine body is always a very difficult problem in automatic hole making for airplane digital assembly. In recent years, the application of a robot hole making technology in the assembly and hole making of the modern airplane body is continuously promoted by the comprehensive advantages of high flexibility, automation, high efficiency and the like. Various novel robotized hole making and hole making systems are emerging continuously.
For example, the american company Electroimpact a flexible rail drilling system, in which a flexible rail robot carrying a drilling end effector is attached to a workpiece by a vacuum cup of the flexible rail during operation. Further, the company Fatronic Tecnalia, Spain has also developed an automated hole making system based on a crawling robot that delivers hole making end effectors to designated locations by an autonomous crawling robot with vacuum suction cups. The two automatic hole making systems adopt a vacuum adsorption technology, and require that the axial force for hole making is not too large, so the two automatic hole making systems are mainly used for processing small hole diameters of airplane bodies. In addition, chinese application (patent) No. 200810121353.1 discloses an industrial robot cutting system and method for aircraft auxiliary assembly, which is not suitable for bearing excessive hole-making axial force due to the weak rigidity of the serial body structure of the industrial robot.
The three types of automatic hole making systems have a certain promotion effect on improving the quality and the efficiency of laminated assembly hole making of the airframe, but due to the special composition structures of the three types of automatic hole making systems, the self bearing capacity is limited to a certain extent, a drilling end effector which needs to be provided with a tool magazine is difficult to attach, a large amount of offline tool changing operations and excessive drilling axial force can seriously affect the efficiency and the quality of laminated hole making of the aviation. With the wider and wider application of difficult-to-machine materials such as titanium alloy, carbon fiber composite materials and the like in structural members of wings and fuselages, the traditional drilling method is very easy to cause the hole making defect of workpieces made of the materials due to the overlarge hole making axial force. Therefore, the development of an end drilling actuator with small cutting force and high automation degree is a better choice for realizing efficient and precise drilling of the current aviation laminated component.
