The lower screw rod 11 is arranged in the sliding groove 2 of the lower guide rail frame 9, the lower screw rod 11 is rotated by rotating the handle 2, the upper guide rail frame 1 is driven to move left and right in the sliding groove 2, so that the left and right positions of the grating ruler are adjusted. The vacuum pump 6 is arranged in the protective shell 5 on the installation plate 4, the vacuum pump 6 is connected with the negative pressure suction disc 7, the negative pressure suction disc 7 can adsorb and fix the grating ruler by starting the vacuum pump 6, so that the grating ruler is prevented from being damaged by the traditional clamp and the fixing efficiency is improved. The angle adjusting mechanism 14 at the lower part can adjust the overall angle of the device, the grating ruler can move in different directions, the installation accuracy is ensured, and the installation error is reduced.

[0028] The angle adjusting mechanism 14 comprises a supporting disc 1401, a limiting rod 1402 is fixedly connected to the lower surface of the supporting disc 1401, the supporting disc 1401 is rotatably connected to a base 1403 through the limiting rod 1402, a driving motor 1404 is fixedly connected to the inside of the base 1403, a guide circular groove 1405 is formed on the surface of the base 1403, when the driving motor 1404 works, the driving motor 1404 drives the supporting disc 1401 to rotate in the guide circular groove 1405 of the base 1403 through the limiting rod 1402, so that the adjustment of the angle of the whole device is realized.

[0034] A rubber support rod is fixedly connected to the lower surface of the support platform 15.

[0035] The implementation principle of the high-precision installation and positioning auxiliary device for grating rulers in this application embodiment is as follows: Personnel activate the vacuum pump 6 inside the protective shell 5. The vacuum pump 6 uses a negative pressure suction cup 7 to adsorb and fix the grating ruler, avoiding potential surface damage to the grating ruler caused by traditional clamps. Furthermore, unlike traditional clamps, it eliminates the need for position adjustment, improving fixing efficiency. When front-to-back position adjustment is required, personnel rotate handle 8 according to actual needs. The rotation of handle 8 causes the upper screw 3 to rotate on the inner wall of the slide groove 2. Since the mounting plate 4 is threadedly connected to the upper screw 3 and slidably connected inside the slide groove 2, the rotation of the upper screw 3 causes the mounting plate 4 to move along the inside of the slide groove 2. The movement of the mounting plate 4 causes the grating ruler adsorbed by the negative pressure suction cup 7 to adjust its front-to-back position until the desired position is achieved. When left-to-right position adjustment is required, personnel hold handle 12 and rotate it according to installation requirements. The rotation of handle 12 causes the lower screw 11 to rotate on the inner wall of the slide groove 10. Because the lower screw 11 is threaded... Connected inside the slider, the rotation of the lower screw 11 drives the upper guide rail 1 to move left and right along the slide groove 10. The movement of the upper guide rail 1 drives the grating ruler mounted on the negative pressure suction cup 7 to adjust its left and right position until it is adjusted to a suitable left and right position. When it is necessary to adjust the installation angle, the drive motor 1404 inside the base 1403 is started. When the drive motor 1404 is working, since its output end is fixedly connected to the lower surface of the support plate 1401, the drive motor 1404 will drive the support plate 1401. 1. Rotation: The support plate 1401 rotates within the guide groove 1405 on the surface of the base 1403 via the limiting rod 1402. Since the limiting rod 1402 and the guide groove 1405 are compatible, this compatibility ensures the tightness and accuracy of the limiting rod 1402 when rotating within the guide groove 1405, making the rotation of the support plate 1401 more stable and precise. This allows for the adjustment of the entire device angle. The adjustment of the device angle drives the grating ruler to move in different positions, ensuring the accuracy of the grating ruler installation and reducing installation errors.
