Rather, these examples are described so that this disclosure will be thorough and complete and will fully convey the scope of this disclosure to those skilled in the art.

[0029] See Figure 1-2 , which shows the positioning part auxiliary adjustment and installation tooling of the present invention, including a bottom plate 1, an adjustment support block 3, an adjustment cushion block 4, a fixing screw 5, an adjustment screw 6 and a connecting screw 7. The adjustment cushion block 4 is placed below the positioning part 2. During actual use, multiple adjustment cushion blocks 4 need to be fixed into a whole through the connecting screw 7 and the first horizontal threaded hole 402. See Figure 4 , the standard height of the adjustment cushion block 4 is 10 mm, and there is a step difference of 0.02 mm in the thickness of the adjustment cushion block 4. The conventional replaceable specifications are 9.9 mm to 10.1 mm. It also includes two first vertical threaded holes 401 in the vertical direction for connecting the positioning part 2 with the threaded holes of the bottom plate 1. The adjustment support block 3 is placed in the horizontal orthogonal direction of the positioning part, in pairs. The adjustment support block 3 is placed on the bottom plate 1 through the fixing screw 5 and the second vertical threaded hole 301. The second horizontal threaded hole 302 on the upper side is used to install the adjustment screw 6. The cross-section of the adjustment support block 3 is a square structure. See Figure 3, there are second vertical threaded holes 301 and second horizontal threaded holes 302 with the same spacing but misaligned with each other in the horizontal plane and the vertical direction. Third horizontal threaded holes 303 for connecting adjacent adjusting support blocks 3 are arranged at both ends in the cross-section direction. The adjusting support blocks 3 can select a suitable placement method according to the size of the positioning part, and the stability of the XY direction adjustment process is ensured by increasing the control range of the adjusting screw 6.

[0030] During operation, the adjustment method includes: controlling the XYZ directions through this auxiliary adjustment tooling. First, one adjusting pad 4 with a standard height of 10 mm needs to be placed at both ends of the lower side of the positioning part. The height difference of the reference hole of the positioning part in the Z direction is measured by using a laser tracker. According to the height difference and the size of the bottom surface of the positioning part, multiple adjusting pads 4 of corresponding specifications are replaced, and they are paved and supported on the lower side of the positioning part 2 through the connecting screw 7.

[0031] The adjusting support blocks 3 are placed in pairs, one on top of the other, and placed around the adjusting pad 4 in the orthogonal direction. The fixing screw 5 passes through the second vertical threaded hole 301 and is connected to the bottom plate 1. The adjusting screw 6 is installed in the second horizontal threaded hole 302 on the upper side, which is used to adjust the transverse reference plane 201 and the longitudinal reference plane 202 of the positioning part, and control the micro-movement of the positioning part in the XY direction;

[0032] After adjusting the positions of the three axes, fix them through the fixing screw 5 and the positioning pin.

[0033] In summary, the present invention realizes the precise movement of the positioning part in the XY direction by adjusting the adjusting screws in all horizontal directions of the adjusting support block, and realizes the compensation in the Z direction by replacing the adjusting pads. Aiming at the uneven force and difficult direction control of the positioning part during the adjustment and installation process, it is converted into the rotation and tightening of the adjusting screw, and it can be recycled and reused, completing the standardized and modular design, and improving the installation work efficiency.
