[0036] When in use, place the adjusting tool as a whole on an operable machine tool workbench, first use a spirit level to level the T-frame 3 by placing a spirit level on the two front supporting raised surfaces 5 at the same time, and placing another spirit level on the two rear supporting raised surfaces 4 at the same time, and adjust the lengths of the first rear telescopic adjustment mechanism, the second rear telescopic adjustment mechanism, and the front telescopic adjustment mechanism until the lengths of the spirit levels are level, which means that the T-frame 3 is considered to be leveled.

[0037] Assuming that the angle to be adjusted is α°, calculate it with tanα, take the horizontal coordinate 100 as the unit, H=tanα*100, and run H upward in the longitudinal coordinate of the machine tool. After the T-frame 3 is leveled, use a micrometer to hit the upper surface of the T-frame 3, and the reading is 0. After running a height H upward in the longitudinal direction, adjust the front telescopic adjustment mechanism so that the micrometer reading in the vertical direction of the horizontal coordinate 100 is still 0, and then fix it with the top screw 13. This adjustment angle is α.

[0038] Place the adjusted T-frame 3 on the machine tool workbench whose angle needs to be adjusted, place two spirit levels on the two front supporting raised surfaces 5 and the two rear supporting raised surfaces 4 of the T-frame 3 respectively, and then use a jack to support the tilting turntable until the spirit level is level, that is, the inclination angle of the workbench has been adjusted to α.

[0039] Install the processed wedge iron into the support position at the bottom of the workbench, detect its contact rate with the workbench, and make the supporting wedge iron match the inclination angle α of the workbench through matching grinding and scraping, and complete the angle adjustment of the tilting turntable.
