Adjustable sensor fastening device

Abstract

The invention discloses an adjustable sensor fastening device, which includes a base fixed on a protective sleeve, a hollow fixing sleeve fixed to the base by a No. 1 fastening screw, and a hollow fixing sleeve fixed to the base by a No. Sealing plate; No. 1 sealing gasket is set between the base and the fixing sleeve, and No. Ⅱ sealing gasket is set between the fixing sleeve and the sealing plate. The sensor is installed in the cavity of the fixing sleeve and is threadedly connected with the inner wall of the fixing sleeve. The wire end of the sensor is locked and fixed by a lock nut, and the lock nut is threadedly connected with the inner wall of the fixing sleeve. The invention has the advantages of convenient adjustment and operation of the double-layer seal, simple locking structure, small operating space requirement and non-interference, which can ensure high sealing performance and meet the high-vacuum environment for the normal operation of high-speed rotating electromechanical equipment, and the position in the fixed sleeve can be passed through The thread is adjusted and locked by the lock nut, the position is adjustable, the operation is convenient, and the sensor wire will not be damaged.

Description

technical field [0001] The invention belongs to a sensor fastening device, in particular to an adjustable sensor fastening device. Background technique [0002] Some high-speed rotating electromechanical equipment is driven by the motor to rotate the rotor at ultra-high speed in the protective sleeve, and this equipment has high requirements for high vacuum. Since the rotor rotates at high speed during normal operation of the high-speed rotating electromechanical equipment, the amplitude fluctuation of the rotor directly affects the service life of the entire equipment. very high. However, for distance measuring sensors with small structures, corresponding fixing sleeves must be designed, which requires that the sensors not only be able to be locked firmly, but also have a certain adjustment range. Vacuum requirements, and easy to operate. [0003] In the prior art, after the position of the sensor in the fixing sleeve is adjusted, it is fixed by pressing the sealing plat...

AI Technical Summary

Problems solved by technology

Its defect is that the thickness of the two layers of rubber pads must be appropriate in the actual operation process, otherwise there may be problems such as the compression rubber pad is too thick and the sealing performance cannot be guaranteed, or the compression rubber pad is too thin and the sensor is not compressed.

In addition, the sealing between the fixed sleeve and the protective sleeve wall and the sealing between the sealing plate and the fixed sleeve require a large and inconvenient operating space.
