A first mounting through hole is provided on one side wall of the through groove, and a second mounting through hole is provided on the other side wall of the through groove. The first mounting through hole and the second mounting through hole are arranged opposite to each other.
[0038] Mounting base 7; The first end of the mounting base 7 is provided with an adjustment through hole, the second end of the mounting base 7 is used for measuring components, and the first end of the mounting base 7 is set in the through groove;
[0039] The transverse adjusting bolt 9 has its threaded end passing through the first mounting through hole, the adjusting through hole, and the second mounting through hole in sequence. The inner wall of the second mounting through hole is provided with a thread that mates with the transverse adjusting bolt 9. The mounting seat 7 is rotatably mounted on the transverse adjusting bolt 9.
[0040] Lateral damping compensation mechanism; the lateral damping compensation mechanism is set between the nut end of the lateral adjusting bolt 9 and the first end of the mounting base 7. The lateral damping compensation mechanism is used to provide continuous lateral elastic potential energy to the mounting base 7.
[0041] In this embodiment, the mechanical structure of this application is closely integrated with the longitudinal damping compensation mechanism and the transverse damping compensation mechanism, which can achieve stability and accuracy during multi-angle rotation. The longitudinal damping compensation mechanism and the transverse damping compensation mechanism can provide continuous longitudinal and transverse elastic potential energy to the rotating structural component of this application, thereby effectively compensating for small displacements or deviations caused by angle changes or external forces. When this application rotates at different angles, the longitudinal and transverse elastic potential energy can absorb vibration and impact, and can also accurately adjust and stabilize the rotation angle and position. This design not only improves the dynamic performance of this application, but also significantly enhances its reliability and accuracy in complex measurement environments.
[0042] Example 2: The difference between this example and Example 1 is that, as Figure 1 , Figure 2 As shown, the adaptive compensation mechanism also includes a self-lubricating friction disk 13. The stepped hole is a three-step hole. An insertion shaft is provided at the center of the top surface of the self-lubricating friction disk 13. The self-lubricating friction disk 13 is fixedly installed in the first step of the three-step hole. The insertion shaft is set in the second step of the three-step hole. The self-lubricating friction disk 13 is provided with a through hole that passes through its own center and the insertion shaft. The top surface of the rotating disk of the shaft disk assembly 12 is in contact with the bottom surface of the self-lubricating friction disk 13.

The large diameter end is set in the through hole and is in contact with the through hole. The top of the small diameter end passes through the third step of the three-step hole and is set in the blind hole.
[0043] In this embodiment, the self-lubricating friction disc 13 generates a lubricating effect through friction, reducing frictional loss and extending service life. Its core principle is the generation of heat through contact between the friction surfaces. This heat is further converted into lubricating oil or grease, thereby forming a lubricating film between the friction surfaces, reducing direct metal-to-metal contact, and lowering wear and energy consumption. This design not only improves the service life of mechanical components but also optimizes the overall performance and efficiency of the mechanical system.
[0044] Example 3: The difference between this example and Example 1 is that, as Figure 1 , Figure 2 As shown, the longitudinal damping compensation mechanism includes:
[0045] Adjust the locking nut 2; the adjusting locking nut 2 is fitted onto the top of the rotating shaft, and a screw passes through the side wall of the adjusting locking nut 2 and the side wall of the rotating shaft in sequence to fix the locking nut 2;
[0046] A set of first disc springs 3; a set of first disc springs 3 consists of three first disc springs 3 connected in series. The set of first disc springs 3 is mounted on the rotating shaft. The top end of the set of first disc springs 3 is in contact with the adjusting locking nut 2, and the bottom end is in contact with the shaft ring of the thrust bearing 4.
[0047] In this embodiment, when there is a slight longitudinal displacement or deviation of the rotating shaft caused by angle change or external force, the first disc spring 3 will be squeezed or stretched relative to its initial state. After the external force or the angle change of the rotating shaft ends, the first disc spring 3 will return to its initial state under the action of its own elastic potential energy, thereby correcting the slight displacement or deviation of the rotating shaft.
[0048] Example 4: The difference between this example and Example 1 is that, as Figure 1 As shown, the lateral damping compensation mechanism is a set of second disc springs 8, which consists of three second disc springs 8 connected in series. The nut end of the lateral adjusting bolt 9 is set in the first mounting through hole. The set of second disc springs 8 is fitted on the lateral adjusting bolt 9. One end of the set of second disc springs 8 is in pressing contact with the nut end of the lateral adjusting bolt 9, and the other end is in pressing contact with the first end of the mounting base 7. At this time, the pressure on the first end of the mounting base 7 can counteract the sum of the gravity of the mounting base 7 and the measuring element set on it, so that the mounting base 7 will not rotate relative to the lateral adjusting bolt 9 under the influence of gravity alone.
[0049] In this embodiment, when there is a slight lateral displacement or deviation of the mounting base 7 due to angle change or external force, the second disc spring 8 will be squeezed or stretched relative to its initial state. After the external force or the shaft angle change process ends, the second disc spring 8 will return to its initial state under the action of its own elastic potential energy, thereby correcting the slight displacement or deviation of the shaft.
[0050] Example 5: The difference between this example and Example 4 is that, as Figure 1 As shown, the adaptive compensation mechanism also includes a set of first washers and a set of second washers 5 fitted on the transverse adjusting bolt 9. The set of first washers includes three first washers, and the set of second washers 5 includes two second washers 5. The second mounting through hole is a countersunk hole. The set of first washers simultaneously press against the first end of the mounting base 7 and a set of second disc springs 8. The second washers 5 are disposed in the countersunk hole and simultaneously press against the first end of the mounting base 7 and the stepped surface of the countersunk hole.
[0051] Example 6: The difference between this example and Example 5 is that both the first gasket and the second gasket 5 are brass gaskets.
[0052] In this embodiment, the brass gasket possesses excellent wear resistance and tensile strength, enabling it to function as a shock absorber and buffer in mechanical equipment, thereby improving equipment stability and service life. Furthermore, the brass gasket also exhibits good corrosion resistance, allowing for long-term use in various environments without easily rusting or being damaged.
[0053] Example 7: The difference between this example and Example 1 is that, as Figure 1 As shown, the mounting base 7 is provided with a fixing through hole that connects the second mounting through hole to the outside. The fixing through hole is provided with a set screw 6 for fixing the lateral adjustment bolt 9.
[0054] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
