Problems solved by technology

[0006] In view of the above analysis, the present invention aims to provide a method for installing a linear displacement sensor to solve the problem that the existing linear displacement sensor is installed in a sleeve-type ball screw pair and usually relies on brush gravity to overcome friction, but when When the fit between the brush installation shaft and the lead screw sleeve is a small gap or a transition fit, the above method of relying on gravity to achieve installation will fail and cause the problem that the sensor cannot be installed

Abstract

The invention relates to an installation method of a linear displacement sensor, belongs to the technical field of sensor installation, and solves the problem that small clearance fit or interference fit between an electric brush installation shaft and a lead screw sleeve cannot be realized due to the fact that the linear displacement sensor is installed in a sleeve type ball screw pair in a manner of overcoming friction by virtue of the gravity of an electric brush in the prior art. According to the invention, the long screw is arranged at the end part of the electric brush so that the length extension of the electric brush is realized, the electric brush and the sleeve nut are matched in place, the outer hexagonal nut is screwed on the electric brush through the inner hexagonal sleeve, the electric brush and the sleeve nut are fixedly connected through the outer hexagonal nut, and the long screw is convenient to disassemble; and the method can adapt to small clearance fit or transition fit between the electric brush and the sleeve nut, enables the electric brush to be rapidly installed in place, can overcome the reverse force of nut screwing through the long screw, and achieves the rapid installation of a linear displacement sensor and a lead screw nut pair.

Description

technical field [0001] The invention relates to the technical field of sensor installation, in particular to a method for installing a linear displacement sensor. Background technique [0002] The linear displacement sensor is composed of a brush and a conductive substrate. The conductive substrate brush can slide along the surface of the conductive substrate and output a displacement signal. During installation, the brushes are fixedly connected to the moving parts, and the conductive substrate is fixedly connected to the base. [0003] The sleeve type ball screw pair is composed of a screw and a sleeve nut. When the screw rotates, the sleeve nut moves linearly under the action of the guide device. In order to make the structure compact and save space, the linear displacement sensor is usually installed inside the lead screw, and a hole is opened in the center of the lead screw, and the linear displacement sensor is installed in it. The top of the linear displacement sens...
