[0037] refer to Figure 1-Figure 3 The rotation adjustment assembly 31 includes a sliding seat 311, a cover plate 312, a rotation adjustment seat 313 and a rotation screw 314. The sliding seat 311 is slidably matched with the base plate 11. The cover plate 312 is detachably connected to the sliding seat 311 with a screw. An end of the horizontal adjustment plate 12 close to the sliding seat 311 is extended with a connecting buckle 121 connected to the sliding seat 311, so that one end of the horizontal adjustment plate 12 is connected to the sliding seat 311 through the connecting buckle 121, and the other end of the horizontal adjustment plate 12 is rotationally connected to the base plate 11 through a rotating pin 122. The rotation adjustment seat 313 is bolted to the base plate 11, and one end of the rotating screw 314 is rotationally connected to the sliding seat 311 and connected to the rotation adjustment seat 313, so that when the rotating screw 314 rotates, the sliding seat 311 is pushed to move, so that the horizontal adjustment plate 12 rotates;
[0038] When the rotation angle of the mounting plate 15 needs to be adjusted, the bolts connecting the horizontal adjustment plate 12 and the base plate 11 are loosened, and the operator rotates the rotating screw 314, so that the rotating screw 314 pushes or pulls the sliding seat 311 to move, and then the sliding seat 311 synchronously drives the horizontal adjustment plate 12 to rotate around the rotating pin 122, thereby adjusting the rotation angle of the mounting plate 15, and the adjustment range is ±1°.
[0039] refer to Figure 1-Figure 3 The longitudinal adjustment assembly 32 includes a longitudinal connection block 321, a longitudinal adjustment seat 322 and a longitudinal screw 323. The longitudinal adjustment seat 322 is bolted to the base plate 11. The longitudinal screw 323 is threadedly connected to the longitudinal adjustment seat 322 and is rotatably connected to the longitudinal connection block 321. The longitudinal connection block 321 is connected to the horizontal adjustment seat, so that the longitudinal screw 323 is connected to the horizontal adjustment plate 12 through the longitudinal connection block 321 and drives the position of the horizontal adjustment plate 12. When the longitudinal screw 323 is rotated, the longitudinal screw 323 drives the longitudinal connection block 321 to move synchronously, so that the horizontal adjustment plate 12 moves synchronously;
[0040] When it is necessary to adjust the longitudinal position of the mounting plate 15 (i.e. the position of the mounting plate 15 in the left and right directions), loosen the bolts connecting the horizontal adjustment plate 12 and the base plate 11, and the operator rotates the longitudinal screw 323, so that the longitudinal screw 323 pushes or pulls the position of the horizontal adjustment plate 12 on the base plate 11 through the longitudinal connecting block 321, thereby adjusting the longitudinal position of the mounting plate 15, and the adjustment range is ±10mm. The horizontal adjustment plate 12 is provided with a long waist hole 4 along its moving direction to avoid interference with the bolts connecting it and the base plate 11 after it moves.
[0041] refer to Figure 1-Figure 3 In order to make the horizontal adjustment plate 12 better drive the height adjustment plate 13 to move, a first connecting protrusion extends from the horizontal adjustment plate 12, and a first connecting groove is opened on the side of the height adjustment plate 13 facing the horizontal adjustment plate 12, and the first connecting protrusion is engaged with the first connecting groove.
[0042] refer to Figure 1 and Figure 3 The lateral adjustment assembly 33 includes a lateral adjustment seat 331 and a lateral screw 332. The lateral adjustment seat 331 is screwed to the horizontal adjustment plate 12. The lateral screw 332 is rotationally matched with the side of the height adjustment plate 13 and is threadedly connected to the lateral adjustment seat 331. When the lateral screw 332 is rotated, the lateral screw 332 pushes or pulls the height adjustment plate 13 to move laterally (i.e., the height adjustment plate 13 moves forward and backward), thereby synchronously driving the mounting plate 15 to move forward and backward laterally.
[0043] When it is necessary to adjust the lateral position of the mounting plate 15 (i.e. the front-to-back position of the mounting plate 15), loosen the bolts connecting the height adjustment plate 13 and the horizontal adjustment plate 12, and the operator rotates the transverse screw 332, so that the transverse screw 332 pushes or pulls the front-to-back position of the height adjustment plate 13 on the horizontal adjustment plate 12, thereby adjusting the front-to-back lateral position of the mounting plate 15, and the adjustment range is ±10mm.
[0044] refer to Figure 1-Figure 3 In order to enable the height adjustment plate 13 to better drive the tilt adjustment plate 14 to move when moving, a second connecting protrusion 131 is provided on the height adjustment plate 13, and a second connecting groove is opened on the side of the tilt adjustment plate 14 facing the height adjustment plate 13, and the second connecting protrusion 131 is engaged with the second connecting groove.
[0045] refer to Figure 1 and Figure 3 The height adjustment component includes a wedge-shaped groove 341 provided on the height adjustment plate 13 and a wedge-shaped block 342 that slides with the wedge-shaped groove 341, so that the wedge-shaped block 342 can slide back and forth in the wedge-shaped groove 341, and the lower side surface of the tilt adjustment plate 14 fits with the upper side surface of the wedge-shaped block 342, so that the height of the tilt adjustment plate 14 relative to the height adjustment plate 13 is controlled by the position of the wedge-shaped block 342 in the wedge-shaped groove 341; the thickness of the two ends of the wedge-shaped block 342 is different and changes linearly, so that one end of the wedge-shaped block 342 is thicker than the other end, and the wedge-shaped groove 341 is the same, that is, one end of the wedge-shaped groove 341 is deeper than the other end and the depth transition is linear; the wedge-shaped block 342 is provided with a long waist hole 4 along its moving direction;
[0046] When the height of the mounting plate 15 needs to be adjusted, the bolts connecting the tilt adjustment plate 14 and the height adjustment plate 13 are loosened, and the wedge block 342 is pushed or pulled, so that the horizontal height of the upper side of the wedge block 342 is raised or lowered through the cooperation between the wedge block 342 and the wedge groove 341, thereby causing the horizontal height of the tilt adjustment plate 14 to rise or fall, thereby causing the horizontal height of the mounting plate 15 to rise or fall.
[0047] refer to Figure 1-Figure 3 At least two wedge blocks 342 are provided and are distributed at both ends of the tilt adjustment plate 14. The tilt adjustment assembly 35 includes a tilt adjustment seat 351 and a tilt screw 352. The tilt adjustment seat 351 is connected to the end face screw of one side of the tilt adjustment plate 14.

The tilt adjustment assembly 35 is provided with a number of groups corresponding to the number of wedge blocks 342. The two groups of tilt adjustment assemblies 35 are respectively distributed on the left and right sides of the same side of the tilt adjustment seat 351.
[0048] refer to Figure 1-Figure 3When the height of the mounting plate 15 needs to be adjusted, the tilt screws 352 in the left and right sets of tilt adjustment assemblies 35 simultaneously push or pull the wedge blocks 342 at both ends to achieve the increase or decrease of the horizontal height of the tilt adjustment plate 14, thereby achieving the increase or decrease of the horizontal height of the mounting plate 15, and the adjustment range is ±1mm; the long waist hole 4 on the wedge block 342 prevents the wedge block 342 from interfering with the bolts on the tilt adjustment plate 14 when moving, and plays a role of giving way.
[0049] refer to Figure 1-Figure 3 When the mounting plate 15 needs to be tilted to the left, only the tilt screw 352 of the left tilt adjustment assembly 35 is rotated, while the right tilt adjustment assembly 35 does not move, so that only the left wedge block 342 moves, thereby making only the left end of the mounting plate 15 tilted, and the adjustment range is ±0.5°;
[0050] When the mounting plate 15 needs to be tilted to the right, the operation is the same as that for tilting to the left, and the adjustment range is ±0.5°, which will not be described in detail here.
[0051] refer to Figure 1-Figure 3 , additionally explained, in order to realize the action of the screw rod pulling the corresponding component, the protruding round block connected to the outer edge of one end of the screw rod can be extended into the hole of the component connected to the screw rod, and then the hole on the component is covered by a cover sheet to restrict the corresponding screw rod to the corresponding component. This is a conventional technical means for those skilled in the art to realize the pulling action, which will not be elaborated here.
[0052] refer to Figure 1-Figure 4 The substrate 11 can be arranged on the bottom plate 16 , so as to be conveniently installed on the test platform. In order to facilitate the installation of the test piece 22 on the mounting plate 15 , a T-slot can be provided on the mounting plate 15 .
[0053] In order to make those skilled in the art more clearly understand the situation of the present invention in practical application, the following is combined with Figure 1 and Figure 4 The test piece 22 is fixed on the mounting plate 15 by the front support 21 and the rear support 23, and then the test platform is adjusted according to the actual situation to improve the coaxiality of the test piece 22, the bearing seat assembly 24 and the high-speed motor 25.
