Abstract

The invention discloses an electromagnetic-type generation device with high precision and super-micro force. The device comprises an annular end cover, a cantilever beam component and a base body which are connected from top to bottom in sequence, the base body is arranged to be in a cylindrical shape with an axial cavity, an annular groove is formed in the outer wall of the base body along the circumference, and a winding coil winds the interior of the annular groove; the cantilever beam component comprises an annular fixing base, a cantilever is connected to the inner circle of the fixing base, and a mounting sheet is connected to the cantilever; the fixing base, the cantilever and the mounting sheet are arranged to be an integrated structure, and a columnar permanent magnet is arrangedon the bottom of the mounting sheet. According to the electromagnetic-type generation device, the micro-Newton level and nano-Newton level applied force can be precisely generated, and the device hasthe advantages of high precision, high response speed and the like and is suitable for a system driven by precise super-micro force.

Description

technical field [0001] The invention designs a device, more specifically, relates to an electromagnetic high-precision ultra-micro force generating device. Background technique [0002] With the development of science and technology, the emergence of new materials and new products, the application of nano-measurement experimental instruments is becoming more and more extensive. The research on the mechanical characteristics of micro-scale components in micro-electromechanical systems (MEMS) requires a high-precision micro-force generation and measurement system. However, at present, the measurement system of micro-force values ​​has not yet formed a unified traceability standard, so it is urgent to research and invent a high-precision ultra-micro-force generating device. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide an electromagnetic high-precision ultra-micro force generating device, ...
