The application method and the working principle of the device are as follows: in use, first the first screw 602 is driven to rotate by operating the second handle 603, so that the first slide 605 moves leftwards, thereby driving the first cursor 607 to synchronously move until the first cursor 607 is aligned with the zero reference line on the first scale 17, then the second screw 706 is driven to rotate by operating the third handle 707, thereby enabling the second slide 704 to move upwards or downwards, when the second slide 704 moves, the cooperating extension plate 709 can drive the meter frame mechanism 8 to synchronously move, thereby playing a role in adjusting the height of the meter frame mechanism 8, By adjusting the height of the dial frame mechanism 8 to be approximately the same as the height of the reference surface 16, then installing the dial gauge 3 into the dial frame mechanism 8, and calibrating, when installing the dial gauge 3, firstly, by unscrewing the fixing bolt 805, the first arc-shaped groove 802 and the second arc-shaped groove 804 generate a gap, so that the dial rod of the dial gauge 3 can be conveniently inserted through the gap, and it is noted that the dial face is an angle convenient for people to observe, then, the pointer of the dial gauge 3 is contacted with the surface of the reference surface 16, and is slowly extruded, so that the pointer in the dial gauge 3 is in a zero position, and then the fixing bolt 805 is locked, thereby fixing the dial gauge 3, Since the position of the reference surface 16 is fixed with the position of the axis of the reference hole 13, the calibration of the dial indicator 3 can be completed by converting the positions of the reference surface 16 and the reference hole 13 and compensating to the actual value of the first cursor 607 on the first scale 17, and the position compensation is positive compensation, the worm wheel shaft of the booster is installed after the position compensation, the worm wheel rod 9 is penetrated to the lower side from the reference hole 13 through the plane bearing 2, the bottom end of the worm wheel head 91 is attached to the top end of the plane bearing 2, the bidirectional threaded rod 404 is driven to rotate by operating the first handle 405, The two fixing blocks 407 are made to approach each other, so that the worm wheel rod 9 can be clamped and fixed, meanwhile, under the action of the V-shaped groove 408, the worm wheel rod 9 is drawn toward the center, so that the worm wheel rod 9 and the reference hole 13 are in a coaxial position relationship, and the accuracy of measurement is improved, then, the dial gauge 3 is adjusted to be suitable for measuring the meridian plane 93 by operating the vertical adjusting mechanism 7 and by referring to the mutual cooperation reference of the second scale marks 711 on the third side plate 702, then, the dial gauge 3 is moved leftwards by the horizontal adjusting mechanism 6 until the measuring head of the dial gauge 3 contacts with any meridian plane 93, then, the horizontal adjusting mechanism 6 is slowly controlled, so that the dial indicator 3 extrudes the meridian plane 93, the scale on the dial indicator 3 is in a zero position, and then the position size of the meridian plane 93 relative to the axis can be measured through conversion, and the conversion mode is as follows: the actual position value of the first cursor 607 on the first scale line 17, plus the value from the reference plane 16 to the axis of the reference hole 13, that is, the current position degree of the meridian plane 93, then operates the crank 504 to drive the worm 503 to rotate, and cooperates with the worm wheel 502 to rotate the rotating shaft 501, when the rotating shaft 501 rotates, the movable plate 401 can be driven to synchronously rotate, the centering mechanism 4 can be driven to integrally rotate and clamped on the fixed block 407 by the worm gear rod 9, so that the worm gear rod 9 is driven to rotate, the angle of the worm gear shaft of the supercharger is adjusted, the rest meridian plane 93 is conveniently measured, the rest meridian plane 93 can be rapidly measured, the measuring efficiency is greatly improved, when the meridian plane 93 needs to measure the data of different heights, the height or position of the dial indicator 3 is adjusted by the mutual matching of the vertical adjusting mechanism 7 and the horizontal adjusting mechanism 6, the position and the size of other heights of the meridian plane 93 can be measured, the universality is better, the method is suitable for the detection of worm gear shafts of superchargers with different specifications, the tool has higher compatibility, improves the working efficiency, has simple structure, and is easy to manufacture because the related parts are all made of conventional materials, thereby reducing the input cost and facilitating the later maintenance.
Although the present invention has been described 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 and changes may be made without departing from the spirit and principles of the present invention.
