[0002] A fine-tuning platform is a mechanical device capable of high-precision, small-range displacement in one or more directions. Its core objective is to achieve precise position control. A typical platform consists of a high-rigidity platform body and a precision guiding mechanism that determines the degrees of freedom of motion. Based on the degrees of freedom of motion, it is mainly divided into single-axis, dual-axis (XY, XR, etc.), three-axis (XYR or XYZ) and tilt adjustment platforms. The application of this platform is extremely wide, covering almost all fields that require precise positioning. In short, the precision fine-tuning platform is a key basic component for achieving "perfect" position control in modern high-end manufacturing and scientific research.
[0003] When existing XR axis fine-tuning platforms experience malfunctions in the electric drive section, such as motor step loss, driver damage, or power failure, operators cannot intervene in time to manually adjust or urgently reset the equipment. This may lead to equipment jamming, workpiece damage, or even safety accidents. To address these issues, the inventors have proposed a multi-angle electric fine-tuning platform. Utility Model Content

In conjunction with this, a switching assembly is provided at one end of both the linkage screw 3 and the drive screw 6. The switching assembly includes an extension platform 8 and a connecting seat 9. The extension platform 8 is detachably mounted on one side of the base 1 and the X-axis moving stage 2. The output motor 31 is slidably mounted on the extension platform 8. The connecting seat 9 is fixed to the end of the drive screw 6 and the linkage screw 3 near the output motor 31. A spring collet 10 is provided in the middle of the connecting seat 9. A locking nut 11 is threadedly connected to the end of the connecting seat 9 near the output motor 31. The drive shaft of the output motor 31 is detachably connected to the spring collet 10. A manual adjustment disc 12 is provided at the end of both the drive screw 6 and the linkage screw 3 away from the spring collet 10.
[0013] The rotary disk 5 is provided with a connecting end 13 at one end near the linkage slide 7. The top surface of the linkage slide 7 is provided with a trajectory adaptation slide 14. A reversing turntable 15 is rotatably provided on the trajectory adaptation slide 14. The reversing turntable 15 is fixedly connected to the bottom surface of the connecting end 13. A sliding guide rail 32 is fixedly provided on the side wall of the X-axis moving stage 2 near the linkage slide 7. A slider 16 that slides with the sliding guide rail 32 is provided on the side wall of the linkage slide 7 near the sliding guide rail 32.
[0014] The end of the spring collet 10 near the connecting seat 9 adopts a long conical sleeve structure, and the end of the spring collet 10 away from the connecting seat 9 adopts a short conical sleeve structure. The middle part of the connecting seat 9 is provided with a receiving groove 17 that matches one end of the long conical sleeve of the spring collet 10. The middle part of the spring collet 10 is provided with a connection position 18 that matches the drive shaft of the output motor 31. Elastic grooves 19 are evenly distributed along the axial direction on the outer surface of the spring collet 10. The elastic grooves 19 extend in the direction of the connection position 18.
[0015] The connecting seat 9 is provided with an external thread 20 at one end near the locking nut 11, and an internal conical step 21 is provided at the middle part of the locking nut 11 away from the external thread 20. The conical surface on the internal conical step 21 abuts against one end of the short conical sleeve of the spring collet 10. Both ends of the outer side of the locking nut 11 are provided with a lever block 22. The output motor 31 is slidably mounted on the extension platform 8 via the guide rail 23 and the mounting platform 24. The mounting platform 24 is provided with a positioning block 25 near the extension platform 8. The positioning block 25 is provided with a positioning hole 26 in the middle.

[0017] The operation process of this utility model is as follows: When it is necessary to manually adjust the platform, the operator can turn the locking nut 11 by turning the lever 22. While the locking nut 11 moves along the external thread 20, the conical surface on the inner conical step 21 of the locking nut 11 gradually separates from one end of the short conical sleeve of the spring collet 10. During the separation process, after the one end of the short conical sleeve of the spring collet 10 loses the axial clamping force caused by the locking nut 11, the spring collet 10 will start to generate axial displacement away from the connecting seat 9 due to its own elastic restoring force. During the movement, the elastic groove 19 that is closed by the axial clamping force will expand. At this time, the clamping effect on the drive shaft of the output motor 31 will be loosened. Finally, the positioning bolt 28 is turned out from the threaded hole 27. After turning it out, the output motor 31 can be moved away by the mounting table 24 and the guide rail 23. After being moved away, the drive screw 6 and the linkage screw 3 can be actively controlled by the manual adjustment disc 12.
