[0002] As a common high-precision measurement substance, gratings are widely used in the precision measurement fields of physical quantities such as displacement, speed, and angle. With the development of optical technology, higher requirements have been put forward for grating technology in terms of high precision, stability, and measurement range. The structures of existing grating clamping devices are diverse and extensive, but most of the adjustment and installation structures need to be customized according to the size of the grating, and the clamping space cannot be flexibly adjusted, with poor universality. At the same time, due to structural limitations, the grating can usually only be adjusted in two degrees of freedom. For a few grating clamping devices with three-degree-of-freedom adjustment, either the clamping device itself has a complex structure, with large processing and assembly difficulties, or the adjustment operation steps are numerous, or the positioning accuracy is poor and it is not easy to operate. In addition, since the existing adjustment device is only for conveniently fixing the grating and adjusting it in the same direction, it cannot make the grating have a rotational degree of freedom and precisely control the angle, resulting in that the grating system usually needs to be disassembled and reinstalled during adjustment, which is very complex and cumbersome. Summary of the Invention

The ball head knob 19 on the middle side of the back surface of the external part controls the internal part 11 to drive the grating to adjust the pitching angle along the X axis through the stretching of the hook-shaped spring 16. The ball head knob 19 on the top surface controls the grating to adjust the rolling angle along the Y axis.

After the grating three-axis adjustment device 2 is inserted into the fixed disk 22, a hexagonal pin rod 27 is inserted through and locked with a threaded knob 28 at the other end. Disk threaded holes 29 corresponding to the fixed disk 22 are provided at the four corners of the rotary disk 23, and the two are fixed by fastening screws 30. A circular through hole matching the diameter of the assembly hole at the center of the bottom surface of the fixed disk 22 is provided at the center of the rotary disk 23. A fixed cylinder 34 matching the diameter of the circular through hole is provided at the center of the upper surface of the bottom support base 24. Two or more elastic connection beads 31 are evenly distributed on the upper part of the side wall of the fixed cylinder 34.

During rotation, the grating clamped on the telescopic grating fixture 1 can be accurately adjusted and positioned by observing the auxiliary angle scale line 32 corresponding to the 360° angle scale line 35.
[0032] According to the attached Figures 1 to 12 , in this embodiment, the specific assembly and adjustment process of the grating angle control device with a rotary base is as follows:
[0033] First, the inverted "L"-shaped telescopic block 4, the "L"-shaped telescopic block 5 and the buckle cylinder 8 are spliced, and the hexagonal loose bolt 9 is tightened to realize the assembly of the telescopic grating fixture 1. Then, the inner part 11 and the outer part 12 are connected through the cross slot 15 by the hook spring 16, and the short pin rod 17 is used to hook and fix the notch at one end of the inner part 11 and the notch at one end of the outer part 12, and the elliptical groove 18 and the circular threaded hole on the left side, the middle side of the back surface, and the right side of the protruding part of the top surface of the inner part 11 and the outer part 12 are aligned, and the ball head knob 19 is rotated and inserted into the three positions of the elliptical groove 18 until the ball head 194 is tangent to the three semicircular pads 20, and the splicing of the grating three-axis adjustment device 2 is completed. Then, the embedded structure 10 of the buckle cylinder 8 of the telescopic grating fixture 1 is completely embedded in the fixture installation hole 15 of the inner part 11, and the assembly of the telescopic grating fixture 1 and the grating three-axis adjustment device 2 is completed. For different grating sizes, the clamping size of the telescopic grating clamp 1 can be adjusted by moving the hexagonal tension bolt 9 up and down, and the pitch, roll and yaw angles of the grating three-axis freedom can be adjusted by rotating the ball head knob 19 corresponding to the three-axis direction on the grating three-axis adjustment device 2.
[0034] Further, the fixed cylinder 34 on the bottom support seat 24 is inserted into the assembly hole of the fixed disk 22 through the circular through hole of the rotating disk 23, and the elastic connection bead 31 on the upper side wall of the fixed cylinder 34 is pressed against the bead groove on the inner wall of the assembly hole of the fixed disk 22, so that the rotary angle control base 3 remains stable and complete, and the fixed cylinder 34 does not affect the relative rotation of the rotating disk 23 and the fixed disk 22. When there is a need for disassembly, a separation force is applied to the bottom support seat 24, the rotating disk 23 and the fixed disk 22, and the elastic connection bead 31 is separated from the bead groove, and the three-layer structure of the rotary angle control base 3 can be disassembled in sequence. The circular hole of the splicing cylinder 21 on the bottom surface of the outer part 12 is aligned with the splicing groove 25 and the splicing cylinder 26, and then aligned along a straight line with the cross-section of the outer circle of the fixed disk 22 as the reference, and the through hole opened along the diameter of the disk is inserted from the incision at one end and pressed against, and the threaded line extending at the other end is locked with a threaded knob 28.

By inserting the splicing cylinder into the splicing column body and at the same time inserting the splicing column body into the splicing groove, the grating three-axis adjustment device is connected to the rotary angle control base. A through hole is provided on the side wall of the fixed disk body and penetrates through the splicing cylinder in the diameter direction of the circular surface of the fixed disk. At the same time, a through hole is also provided at the corresponding position perpendicular to the median line on the splicing column body through penetration cutting. After the grating three-axis adjustment device is inserted into the fixed disk, a hexagonal pin rod is inserted through and locked with a threaded knob at the other end. Disc threaded holes corresponding to the fixed disk are provided at the four corners of the rotating disk, and the two are fixed with fastening screws. A circular through hole that matches the diameter of the assembly hole at the center of the bottom surface of the fixed disk is provided at the center of the rotating disk. A fixed cylinder that matches the diameter of the circular through hole is provided at the center of the upper surface of the bottom support base. Elastic connection beads are evenly distributed on the upper part of the side wall of the fixed cylinder. A matching bead groove is provided on the inner wall of the assembly hole provided at the center of the bottom surface of the fixed disk. The fixed cylinder is inserted into the assembly hole at the center of the bottom surface of the fixed disk through the circular through hole of the rotating disk, and the elastic connection beads are embedded in the bead groove to connect the bottom support base, the fixed disk, and the rotating disk into one body.
7. The grating angle adjustment device with a rotating base according to claim 6, characterized in that: Two or more elastic connection beads are evenly distributed on the upper part of the side wall of the fixed cylinder.
8. A grating angle adjustment device with a rotating base according to claim 6, characterized in that: Auxiliary angle scale lines and a handle are provided on the outer circumferential surface of the rotating disk. 360° angle scale lines are provided on the outer circumferential surface of the bottom support base. The fixed disk and the rotating disk are relatively fixed, and the two disks and the grating three-axis adjustment device are driven to rotate synchronously by operating the handle.
