Technical Field

[0001] This utility model relates to the field of positioning tooling technology, specifically to a positioning tooling for a micro / nano pin. Background Technology

[0002] Micro / nano pins are specialized tools used in micro / nano fabrication and precision manipulation. Their structural dimensions are typically on the micrometer or nanometer scale, and their function is similar to a miniaturized version of a traditional pin. They are primarily used for support, positioning, or transmitting microforces, playing a crucial role in scenarios such as microelectromechanical systems (MEMS), semiconductor inspection, and biological micromanipulation.

[0003] When using traditional positioning fixtures to fix micro / nano ejectors, the current operating mode requires workers to hold the ejector with one hand and operate the fixture with the other to complete the centering and installation. This method, which occupies both hands, is not only cumbersome to operate, but also greatly affects the efficiency and convenience of installation. Utility Model Content

Then, the pressure roller located inside the bracket will fit tightly against the square frame, freeing the workers' hands and completing the positioning of the outer shell and the centering of the ejector pin, greatly improving the efficiency and convenience of installation.

[0008] In a preferred embodiment, the present invention can be further configured such that: the outer shell is composed of a hemispherical shell and a square frame, the square frame is integrally formed on the top of the hemispherical shell, and multiple pressure rollers are respectively attached to multiple outer walls of the square frame.

[0009] In a preferred embodiment, the present invention can be further configured such that a rubber sleeve is fixedly connected inside the tube body, and the length of the rubber sleeve is less than the length of the tube body.

[0010] In a preferred embodiment, the present invention can be further configured such that: a base plate is attached to the bottom of the outer shell, and the bottoms of the four support frames and the four cylinders are all fixedly connected to the top of the base plate in a matrix.

[0011] In a preferred embodiment, the present invention can be further configured such that two reinforcing ribs are fixedly connected between the support frame and the base plate, and the reinforcing ribs are configured as triangles.
