Referring to FIG. 1, a partial block diagram of a vehicle instrument is provided.

In manufacturing, an operator assembles the upper bearing 120 and the first nut 130 in sequence, but during the assembly process, the upper bearing 120 is likely to rotate together with the first nut 130, and thus, it is difficult to precisely control the position of the upper bearing 120, and thus, it is difficult to control the gap between the middle shaft 110 and the lower bearing 140.
In measurement, the protruding height of the middle shaft 110 is detected, and then the gap between the middle shaft 110 and the lower bearing 140 is calculated through the specification and the size of the upper bearing 120 and the middle shaft 110, but the upper bearing 120 and the middle shaft 110 have deviation in manufacturing, and the calculated gap has deviation from the actual situation.

In summary, the working principle of the embodiment is as follows:
1. in assembly, the bracket 100, the upper bearing 120 and the first nut 130 are fixed by the rotation of the outer tube 310 and the middle tube 320, the number of rotation turns of the middle tube 320 is controlled by the second motor 350, thereby defining the installation position of the upper bearing 120, specifically, the upper bearing 120 can be rotated to the bottom, then the upper bearing 120 is retracted for the corresponding number of rotation turns, the distance that the upper bearing 120 is raised when the upper bearing 120 is retracted is equal to the maximum gap between the middle shaft 110 and the lower bearing 140, and then, the outer tube 310 is rotated, so that the first nut 130 fixes the bracket 100 and the upper bearing 120.
The specific assembly method is as follows:
① the third cylinder 280 drives the lifting frame 300 to descend, so that the buffer column 366 and the positioning block 210 cooperate to fix the support 100, and at the same time, the outer tube 310 is pressed tightly against the first nut 130, and the middle tube 320 is pressed tightly against the upper bearing 120.
② the first motor 340 rotates to drive the outer tube 310 to rotate, so that the first nut 130 rotates and descends, and the first nut 130 is completely sleeved on the upper bearing 120 to prevent the first nut 130 from loosening when the upper bearing 120 rotates.
③ the first motor 340 rotates in a reverse direction to lift the first nut 130, so that the first nut 130 and the bracket 100 have a gap therebetween without affecting the rotation of the upper bearing 120.
④ the first motor 340 stops and the second motor 350 rotates, causing the upper bearing 120 to rotate downward until the upper bearing 120 cannot rotate any further, at which point the gap between the central shaft 110 and the lower bearing 140 is zero.
⑤ the second motor 350 rotates in reverse to lift the upper bearing 120 by a distance equal to the maximum clearance between the central shaft 110 and the lower bearing 140.
⑥ the second motor 350 is stopped and the first motor 340 is rotated to raise the first nut 130 to ensure that the first nut 130 does not become jammed.
⑦ the first motor 340 is rotated in the opposite direction and the first nut 130 is lowered to secure the bracket 100 and the upper bearing 120 together, completing the assembly.
⑧ the third cylinder 280 drives the lifting frame 300 to rise, so that the outer tube 310 is separated from the first nut 130, the middle tube 320 is separated from the upper bearing 120, then the first cylinder 240 drives the positioning block 210 to return, and the operator unloads the materials.
2. In detection, the center shaft 110 is jacked, so that the center shaft 110 jacks up the inner core 330 and the measuring arm of the micrometer 360, the actual gap is determined through reading change, the conversion error is reduced, and especially, the influence caused by the manufacturing difference of the upper bearing 120 is avoided.
