Problems solved by technology

[0003] Although the use of precision nuts can achieve good locking requirements compared with ordinary nuts, precision nuts may still loosen due to vibration or other external influences generated during the operation of the equipment
After the precision nut is loose, the user has no way of knowing that the precision nut has been loose, which leads to a decrease in the accuracy of the equipment, and more serious cases may further lead to equipment failure or even industrial safety accidents.

Embodiment Construction

[0041] In order to illustrate the present invention more clearly, preferred embodiments and drawings are given in detail as follows. Please refer to Figure 1 to Figure 3 As shown, the precision nut 1 according to the first preferred embodiment of the present invention includes a body 10 , a vibration sensor 20 , a closure 30 , a readout circuit 40 and a power supply device 50 .

[0042] The body 10 has a screw hole 12 and a recess 14, wherein the screw hole 12 runs through the opposite end surfaces 10a of the body 10, and the screw hole 12 is screwed with a screw (not shown) of the device (not shown). The cavity 14 is formed by indenting from the outer peripheral surface of the body 10 , and is not limited thereto, and may also be formed by indenting from one end surface 10 a of the body 10 .

[0043] The shock sensor 20 is disposed in the cavity 14 and electrically connected to the readout circuit 40 . When the shock sensor 20 detects the vibration of the main body 10 , the...

Abstract

The invention discloses a precise screw cap. The precise screw cap comprises a body; and the body is provided with a screw hole, moreover, the body comprises a vibration sensor which is arranged on the body, wherein the vibration sensor is used for detecting the vibration of the body and outputting an electric signal corresponding to the vibration sensor. Therefore, when the body vibrates, the electric signal of the vibration sensor can reflect the vibration degree for subsequent judgment.

Description

technical field [0001] The present invention relates to precision nuts; in particular, it refers to a precision nut capable of sensing vibration. Background technique [0002] Precision nuts are widely used in various equipment, such as processing machines, precision machinery, instruments and other objects that need to be locked. Among them, the aforementioned equipment has certain assembly requirements for the joint parts to ensure the reliability of the equipment and Precision, therefore, requires the use of precision nuts to secure the device. [0003] Although the use of precision nuts can achieve good locking requirements compared with ordinary nuts, the precision nuts may still be loosened due to vibration or other external influences generated during the operation of the equipment. After the precision nut is loosened, the user has no way of knowing that the precision nut has been loosened, which leads to a decrease in the accuracy of the equipment, and more serious ...
