A nut that can display the pressure value

Abstract

The invention belongs to the field of nuts, in particular to a nut capable of displaying pressure values, which includes a ring sleeve A, a ring sleeve B, a guide rod A, a limit block A, a ring sleeve D, a guide rod B, a limit block B, a screw Sleeve, ring sleeve E, spring A, spring B, limit mechanism, wherein the ring sleeve A that matches the side of the part to be connected is rotated and fitted with ring sleeve B, and the end surface of ring sleeve B is evenly installed with three guide rods A in the upper direction ; The present invention does not need to use a torque wrench when connecting equipment or parts in the high-end manufacturing industry to generate the required fastening pressure as required, and the size of the fastening pressure is the indicated value of the end face of the ring sleeve E on the guide rod B, thereby Reach the tightening pressure when the bolts and nuts advance to the equipment or components, so that the tightening pressure of the bolts on the equipment or components is moderate without causing damage to the equipment or components.

Description

technical field [0001] The invention belongs to the field of nuts, in particular to a nut capable of displaying pressure values. Background technique [0002] High-end manufacturing refers to newly emerging industries with high technology content, high added value and strong competitiveness in the manufacturing industry. The requirements for the bolts and nuts used in the high-end manufacturing industry are also relatively high, and the bolts and nuts in the high-end industry have moderate tightening pressure on the two connected devices or components. If the fastening pressure is too large, it will cause damage to the two connected devices or components; if the fastening pressure is too small, it will not be able to play the role of connecting and fastening the two devices or parts. [0003] In high-end manufacturing industries, torque wrenches are usually used to install bolts and nuts to provide moderate tightening pressure. However, the torque wrench cannot be fully ap...

AI Technical Summary

Problems solved by technology

However, the torque wrench cannot be fully applied to different installation environments due to its small shape and variety.

At this time, the bolts and nuts can only be installed with corresponding ordinary wrenches, which leads to the fact that the tightening pressure of the bolts and nuts after tightening cannot be guaranteed to be moderate.

At the same time, in order to prevent the traditional bolts and nuts from loosening or even falling off due to the vibration of equipment or components during use, auxiliary anti-loosening and anti-loosening auxiliary parts are usually added, or the nuts are specially designed for self-locking and anti-loosening Detachment, resulting in low efficiency of bolt and nut installation and increased cost of nut design and production
