AI Technical Summary

Technical Problem

In the existing technology, it is difficult to ensure that the axis of the sensor bracket and the measuring hole are aligned during the installation process of the deep hole sensor bracket, which leads to wear and installation difficulties.

Method used

The sensor bracket employs a circumferential support, a laser emitting unit, a support guide tube, and an adjustment mechanism. The laser emitting unit calibrates the axis of the measuring hole, and the adjustment mechanism adjusts the support guide tube to make it coaxial with the measuring hole. Combined with a ball joint structure and a sliding support, the sensor bracket can be precisely aligned and installed.

Benefits of technology

This method enables coaxial installation of the sensor bracket and the measuring hole axis, avoiding wear and deformation, ensuring the stability and accuracy of the installation process, and reducing the difficulty of implementation.

Abstract

This invention discloses a deep-hole sensor bracket mounting device with a centering function, solving the problem in existing technologies where it is difficult to ensure that the axis of the sensor bracket and the measuring hole are aligned when installing the sensor bracket with the deep-hole sensor into the measuring hole, leading to wear of the deep-hole sensor. Specifically, it includes a circumferential support, a laser emitting unit, a bracket guide tube, and an adjustment mechanism. The laser emitting unit is mounted at one end of the circumferential support, and the other end is used to support the sensor within the measuring hole to calibrate the hole axis. The light emitted by the laser emitting unit is aligned with the axis of the circumferential support. One end of the bracket guide tube is hinged to one end of the circumferential support. The adjustment mechanism is rotatably connected to the bracket guide tube for adjusting the position and angle of the bracket guide tube. This invention ensures that the sensor bracket and the measuring hole are coaxial, avoiding rubbing and wear of the deep-hole sensor due to misalignment between the sensor bracket and the measuring hole axis.
