Processing method and device for flexible structural component

Abstract

The invention discloses a processing method and device for a flexible structural component. The processing method comprises the following steps that an electrode is processed to enable the surface shape and the accuracy of the discharge surface of the electrode to be matched with those of the flexible structural component; the electrode is installed on a machine tool with the functions of rotation and vertical displacement to enable the electrode to be coaxial with a Z shaft of the machine tool; a workpiece is clamped on a workbench and is coaxial with the Z shaft of the machine tool; the discharge surface of the electrode and the workpiece are submerged into an electrolyte; the electrode is connected with a cathode of a direct-current power supply, the workpiece is connected with an anode of the direct-current power supply, and the machine tool is controlled to enable the electrode to rotate at a certain constant speed; the Z shaft of the machine tool is controlled to enable the discharge surface of the electrode to gradually approach the workpiece and generate the electrochemical corrosion effect; and the surface of the workpiece is continuously electrolysed until the shape of the surface of the workpiece is consistent to that of the discharge surface of the electrode so as to obtain the flexible structural component. According to the processing method, the flexible structural component can be processed with high accuracy.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a processing method and device for a flexible structural member. Background technique [0002] Compared with the traditional rigid structure, the flexible structure has the advantages of reducing the number of components, no friction, wear and transmission gap, small invalid stroke, high-precision movement, elastic energy storage, self-return reaction force, small assembly stress, etc. advantage. This makes it widely used in microelectromechanical systems (MEMS), precision motion regulation, stress-free assembly, and bionic machinery. Especially in the optical projection objective lens system, in order to meet the requirements of small support stress and high precision of the motion mechanism, a large number of flexible structures are used. But at the same time, due to the low stiffness of the flexible structure itself, there are currently disadvantages such as manufacturin...

Problems solved by technology

But at the same time, due to the low stiffness of the flexible structure itself, there are currently disadvantages such as manufacturing difficulties and machining accuracy, which seriously limit the performance and application fields of the flexible structure.

[0003] When traditional milling and turning processes are used in the early stage, and due to the large cutting force generated by milling and turning, large processing stress will be introduced into the structure. , there is a large deformation, which affects the accuracy of the flexible element
