Before and after the measurement, the air-float slide rail 2 can be cleaned automatically, the transmission motor 29 drives the transmission screw rod 26 to rotate through the driving transmission shaft 30, thereby driving the movable sleeve rod 31 to move back and forth along the axial direction of the limiting guide rod 27 through the threaded sleeve 32, thereby driving the absorbent cotton cleaning pad 35 to clean the air-float slide rail 2, as shown in fig. 7, ensuring the surface cleaning of the air-float slide rail 2, reducing the influence on the sliding of the float block 3, enabling a plurality of cleaning agent storage bottles 36 to be loaded with cleaning agents such as alcohol and the like, dripping the cleaning agents into the surface of the absorbent cotton cleaning pad 35 through the dropper 37 and being absorbed and diffused by the absorbent cotton cleaning pad 35, improving the cleaning effect, and when the cleaning is carried out to the position of the float block 3, enabling the rotatable cleaning rod 33 to enable the absorbent cotton cleaning pad 35 to pass through the side part of the float block 3, and enabling the cleaning rod 33 to reset for cleaning, thereby cleaning the whole air-float slide rail 2, and being convenient and simple to operate.
After the absorbent cotton cleaning pad 35 is used for a long time, as shown in fig. 7, the limit sliding sleeves 40 on two sides of the sliding sleeve can be slid to release the limit of the mounting plate 38, then the lifting rod 43 is pulled to drive the limit pins 39 to be pulled out of the absorbent cotton cleaning pad 35 through the mounting plate 38, so that the limit of the absorbent cotton cleaning pad 35 is released, the absorbent cotton cleaning pad 35 can be removed for cleaning or replacement, and the absorbent cotton cleaning pad is quite convenient, meanwhile, the cleaning blower 42 moves along with the movable sleeve rod 31 in the cleaning process, so that impurities, dust or small parts on the air-float sliding rail 2 can be blown away by wind force, and the impurities are prevented from scratching the surface of the air-float sliding rail 2 or damaging the air-float sliding rail 2, so that the service life of the air-float sliding rail 2 is reduced.
Finally, it should be noted that: the foregoing description is only illustrative of the preferred embodiments of the present application, and although the present application has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described, or equivalents may be substituted for elements thereof, and any modifications, equivalents, improvements or changes may be made without departing from the spirit and principles of the present application.
