the bracket body is a plate-type bracket or an L-shaped bracket or a shaft displacement main bracket, the second fastening piece and the first fastening piece are of block structures, and the first fastening piece and the bracket main body are integrally formed;
specific example 1:
2-4, the novel bracket of the eddy current sensor comprises a bracket main body 1 and a fastener 2; the fastening piece 2 comprises a first fastening piece (2-1) and a second fastening piece (2-2), the support main body 1 is a plate-type support, the first fastening piece (2-1) and the second fastening piece (2-2) are of a block structure, the first fastening piece (2-1) and the support main body 1 are integrally formed, the second fastening piece (2-2) and the first fastening piece (2-1) are in butt joint to form a screw hole 3 with a complete middle part, and the first fastening piece (2-1) and the second fastening piece (2-2) limit the sensor in the screw hole 3 and fix the sensor through a screw 4.
The present embodiment is suitable for mounting a PR6423 sensor.
Or the whole fastening piece is of a hoop body structure and comprises a fastening part and an inserting part, the fastening part comprises a first fastening piece and a second fastening piece which are arranged in two halves, the first fastening piece and the inserting part are integrally formed, the inserting part and the bracket main body are welded into a whole, the second fastening piece and the fastening piece are butted to form a screw hole, and the sensor is limited in the screw hole through screw fixation;
more specifically, the bracket body is a plate bracket or an L-shaped bracket or a shaft displacement main bracket, and the second fastening piece and the first fastening piece are of block structures;
specific example 2:
the novel support of the eddy current sensor comprises a support body 1 and a fastener 2; the bracket body 1 is an L-shaped bracket, and the bracket body 1 is provided with a mounting hole; the whole fastener 2 is of a hoop body structure, and is inserted into the mounting hole of the body 1 and then welded into a whole, see fig. 5.
The fastener 2 is of a two-half hoop body structure, one half is an insertion part, and the other half is a fastening part; the two parts are butted to form a complete screw hole 3 for mounting the eddy current sensor and are locked by a screw 4.
The bracket shown in fig. 5 is suitable for mounting a PR6423 sensor and the bracket shown in fig. 6 is suitable for mounting a PR6424 sensor.
Or the whole fastener is an external thread pipe with an opening on the side surface, the mounting hole is provided with internal threads matched with the external thread pipe, two locking nuts are sleeved outside the external thread pipe, and the sensor is locked by the locking nuts after being inserted into the external thread pipe;
