Abstract

The present invention relates to a high-precision sensing pushrod, comprising a housing, a first sensing element, a second sensing element, a fixed post, a connecting shaft, and a contact block. The high-precision sensing pushrod of the present invention contacts a test object directly through the contact block to fully and accurately convey the vibration state of the test object. This design can: 1. avoid interference between different signals caused by the reaction force generated when the first and second sensing elements traditionally contact the test object directly, thereby eliminating measurement errors and achieving high-precision micro-vibration detection; and 2. actively or passively suppress the vibration of the test object to achieve precise force and displacement control.

Dependent claims

A high-precision sensing pushrod, comprising:

a housing;
a first sensing element configured within the housing;
a second sensing element configured within the housing;
a fixed post for securing the first sensing element;
a connecting shaft, wherein one end of the connecting shaft is connected to the first sensing element;
and
a contact block configured at the other end of the connecting shaft;
wherein the second sensing element is connected to the connecting shaft, positioned between the first sensing element and the contact block through the connecting shaft, and affixed to the contact block;
wherein the contact block is designed to directly contact a test object, to avoid an impact of a reaction force generated when the first sensing element and the second sensing element directly contact the test object, thereby enabling the first sensing element and second sensing element to achieve high-precision detection of micro-vibrations of the test object through the contact block.
