Adjustable sensor installation platform

Abstract

The invention discloses an adjustable sensor installation platform. The adjustable sensor installation platform comprises a fixed base, a rotary platform, a sliding platform, a sensor fixing platform, a rotary platform push-pull rod, a sliding platform push-pull rod, a first micrometer head and a second micrometer head; a vertical panel of the fixed base and the rotary platform form a rotary pair to enable the rotary platform to rotate on the vertical surface around the fixed base; a fixed casing pipe of the first micrometer head is fixed on a side panel of the fixed base, a micrometric screw of the first micrometer head penetrates through the side panel of the fixed base and is fixedly connected with one end of the long edge of the rotary platform push-pull rod, and the rotary platform push-pull rod slides to drive the rotary platform to rotate; the rotary platform and the sliding platform form a movable pair, and a micrometric screw of the second micrometer head is connected with the sliding platform through the sliding platform push-pull rod and can drive the sliding platform to vertically move; the sensor fixing platform is horizontally fixed to the sliding platform. The adjustable sensor installation platform is simple in structure, convenient to install and capable of accurately adjusting the installation position and angle of a sensor.

Description

technical field [0001] The invention relates to a sensor installation platform, in particular to an adjustable sensor installation platform. Background technique [0002] The whirling vibration of ship propulsion shafting is an important form of ship propulsion shafting vibration. When the eddy current sensor is used to measure the whirling vibration of the ship shafting, according to the measurement principle, in order to reduce the error caused by the vibration of the hull, the eddy current sensor is generally used It is installed near the intermediate bearing at an angle of 45 degrees to the vertical direction. When the eddy current sensor is installed, it is necessary to ensure that the distance between the eddy current sensor and the measured axis is near the midpoint of the eddy current sensor's measurement linearity. [0003] At present, eddy current sensors are installed with custom-made tooling for specific conditions. Even so, due to the difference between the act...

Problems solved by technology

[0003] At present, eddy current sensors are installed with custom-made tooling for specific conditions. Even so, due to the difference between the actual contact surface and the design state and the installation state of the tooling, the installation angle of the eddy current sensor cannot be 45 degrees. It is guaranteed, and the design accuracy and installation accuracy of the tooling are high; in addition, when the eddy current sensor is installed, it is necessary to ensure that the sensor is at the midpoint of its working linearity. At present, the eddy current sensor is measured with a feeler gauge when the sensor is installed. The distance between the end face of the probe and the surface of the measured shaft, and then lock the nut on the eddy current sensor probe to realize the installation of the sensor, so that when the nut is locked, the pressure of the sensor probe on the feeler gauge may increase and react on the installation tool The tooling is elastically deformed, which causes the distance between the end face of the eddy current sensor probe and the measured shaft to decrease due to the recovery of the tooling deformation after the feeler gauge is pulled out, which affects the measurement accuracy, and the installation workload is large. The technical status of the installers is relatively high
