In the process of using laser interferometer for measurement and compensation, not only is it very demanding on the surrounding environment, but it also requires the operator to be highly proficient in the layout and installation and calibration of the mirror group. In the actual operation process of using laser interferometer to measure the positioning error of each linear motion axis of CNC machine tools, a lot of time is often spent on mirror calibration.

[0003] According to a publicly disclosed laser interferometer measurement and alignment tool (Announcement No.: CN218723881U), the above application includes a base plate and an adjustment mechanism; the base plate includes a laser interferometer fixing area and a mirror group fixing area; the adjustment mechanism is connected to the base plate to support the base plate, and when the tool is arranged on a horizontal reference plane, the adjustment mechanism is also used to adjust the levelness of the base plate.

[0004] However, in actual use, the above-mentioned equipment needs to be repeatedly calibrated with a spirit level to see if the base plate is in a horizontal position. If the base plate is not horizontal, the adjustment bolt needs to be turned to make the spirit level. This takes a lot of time to ensure the levelness of the base plate, thereby reducing the time required to arrange the laser interferometer. In view of this, we proposed a laser interferometer measurement mirror tooling. Utility Model Content

The rotating shaft 301 and the rotating rod 401 are vertically arranged, and a gap is provided between the mounting arc plate 2 and the rotating sleeve 302, and a gap is provided between the rotating sleeve 302 and the movable hemisphere 403.

[0027] The limiting device 5 is arranged inside the movable hemisphere 403, and the limiting device 5 includes a second mounting frame 501, a through slot 502, a clamping slot 503, a movable column 504, a clamping block 505, a piercing cone 506, and a pull ring 507. The top of the second mounting frame 501 is provided with a through slot 502 and a clamping slot 503, and the inner wall of the second mounting frame 501 is sleeved with a movable column 504, the side wall of the movable column 504 is fixedly connected with the clamping block 505, the bottom end of the movable column 504 is fixedly connected with the piercing cone 506, the movable column 504 is socketed with the inner bottom surface of the movable hemisphere 403, and the end of the movable column 504 away from the piercing cone 506 is fixedly connected with the pull ring 507.

[0028] The rotating shaft 301 is hollow, and a threaded groove is provided on the inner wall of the rotating shaft 301. The rotating shaft 301 is threadedly connected to the bolt 1 303. The rotating rod 401 is hollow, and a threaded groove is provided on the inner wall of the rotating rod 401. The rotating rod 401 is threadedly connected to the bolt 2 402.

[0029] The structure and use method of the mirror tool body 6 are consistent with the structure and use method of the reference document cited in this application document (a laser interferometer measurement mirror tool, publication number CN218723881U). The linear reflector is installed according to the first direction measurement point and tightly connected to the second direction of the linear beam splitter through long fixing bolts. The linear beam splitter is fixed to the fixed area of ​​the mirror group through corresponding bolts. After installation, the laser interferometer emitting lens and the linear beam splitter are located in the same straight line. Thereafter, the tool is placed on a horizontal reference plane, the level is checked with a spirit level, the level is adjusted through the adjustment mechanism, and then another linear reflector is installed on the first direction axis to be measured, so that the light emitted by the laser interferometer can smoothly return to the emission point to achieve the mirror calibration operation.

[0030] Place the device flat on a horizontal reference plane. With the action of gravity, the rotating sleeve 302 rotates along the rotating shaft 301 and the movable hemisphere 403 rotates along the rotating rod 401, thereby rotating the mounting frame 404 to a horizontal position.

[0032] In addition, by using bolt 1 303 to fix rotating part 1 3 and bolt 2 402 to fix rotating part 2 4, the adjustment component can be completely fixed, further preventing accidental shaking of the adjustment component during transportation and use of the laser interferometer, ensuring that the adjustment component remains completely stable during use, avoiding measurement errors caused by accidental collisions or vibrations, and avoiding damage to the equipment caused by shaking, thereby ensuring the accuracy and integrity of the equipment.

[0033] In the present invention, when in use, the device is placed flat on a horizontal reference plane. As gravity acts, the mounting frame 404 rotates to a horizontal position, and the piercing cone 506 pierces the bottom plate of the frame body 1. Then, the rotating part 1 3 is fixed with the bolt 1 303, and the rotating part 2 4 is fixed with the bolt 2 402, so that the adjustment component can be completely fixed.
