The inner wall of the upper seat body 1 is provided with an inner hole, and the upper seat body 1 is installed with a lifting column 3 through the inner hole. The bottom end of the outer side of the lower seat body 2 is provided with a groove, and the lower seat body 2 is installed with a limit block 9 through the groove. The lower seat body 2 fixes the limit block by the third hexagon socket screw 11, and the bottom end of the lower seat body 2 is provided with a guide To the groove, the lower seat body 2 is installed with a wedge block 8 through the guide groove, the bottom end of the jacking column 3 is the wedge block 8, the bottom end of the jacking column 3 is a first inclined surface inclined downward, and the top of the wedge block 8 is a second inclined surface inclined upward, the first inclined surface and the second inclined surface are fitted together, one side of the wedge block 8 is the inner wall of the lower seat body 2, and the other side of the wedge block 8 is provided with a threaded hole, and the wedge block 8 is installed with a hexagonal screw 14 through the threaded hole, and the other side of the lower seat body 2 is provided with a screw hole, and the hexagonal screw 14 passes through the lower seat body 2 through the screw hole, and a locking nut 18 is installed between the hexagonal screw 14 and the inner wall of the lower seat body 2, and a set screw 19 is installed in the locking nut 18, and the other side of the hexagonal screw 14 is connected to the extended sleeve wrench 15 through a tightening screw, and the bottom end of the extended sleeve wrench 15 is a sleeve wrench bracket 16, and the bottom end of the sleeve wrench bracket 16 is the ground.

[0032] In this embodiment, before the large turntable A is started, the original height of the equal-height shims B is adjusted by processing the cross-section of the copper flange 4, so that the four equal-height shims B can be kept in an equal-height state; after the large turntable A is started, when the height is not enough for use or the equal-height state needs to be ensured, the extended sleeve wrench 15 is rotated, and the extended sleeve wrench 15 drives the hexagonal screw 14 to rotate synchronously, and the hexagonal screw 14 synchronously drives the wedge block 8, and the wedge block 8 slides forward through the guide groove of the lower seat body 2, and the sliding distance of the wedge block 8 is limited by the limit block 9.

The initial heights of the contour shims are adjusted by means of a copper flange, and the distances between the contour shims are adjusted by rotating an extended sleeve wrench. This allows the contour shims of the large turntable to not only have an initial state of equal heights, but also to have their heights adjustable as needed. This has the advantage that, while ensuring the accuracy of the workpiece being processed, the adjustment time before processing is greatly shortened, the labor intensity of the operator is reduced, and the processing efficiency of the large turntable is improved.
