[0037] When in use, place the entire adjusting tool on a workbench of an operable machine tool. First, level the T-frame 3 with a spirit level by placing a spirit level on the two front support raised surfaces 5 at the same time, and another spirit level on the two rear support raised surfaces 4 at the same time. Adjust the lengths of the first rear telescopic adjustment mechanism, the second rear telescopic adjustment mechanism, and the front telescopic adjustment mechanism until they are level with each spirit level. This means that the T-frame 3 is considered to be leveled.

[0038] Assume the required adjustment angle is α°. Calculate it using tanα, with the horizontal coordinate at 100° as the unit, H = tanα * 100. Run H upward in the machine's longitudinal coordinate. After leveling the T-frame 3, use a dial indicator on its upper surface to read 0. Run a height H upward in the longitudinal direction, then adjust the front telescopic adjustment mechanism so that the dial indicator reading in the vertical direction of the horizontal coordinate at 100° remains 0. Secure it with the jackscrew 13. This adjustment angle is α.

[0039] Place the adjusted T-frame 3 on the machine tool workbench whose angle needs to be adjusted, and 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. Then use a jack to support the tilting turntable until it is level with the spirit level, that is, the workbench inclination angle has been adjusted to α.

[0040] 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 fit the inclination angle α of the workbench through matching grinding and scraping, and complete the angle adjustment of the tilt turntable.

Ordinary technicians in this field should understand that the present invention can still be modified or replaced by equivalents to achieve the same technical effects; as long as the use requirements are met, they are within the scope of protection of the present invention.
