[0002] The SHINE superconducting cavity is the core accelerating component of the Shanghai Hard X-ray Free Electron Laser Facility. It is used to accelerate electron beams in a low-temperature environment to generate high-brightness X-rays. The main structure is made of high-purity niobium plate by stamping and welding to ensure ultra-high precision and smoothness of the inner surface.

[0003] Existing positioning devices for superconducting cavity surface treatment are prone to causing the positioning position to shift when clamping and positioning the superconducting cavity, making it difficult for operators to quickly and accurately fix the superconducting cavity in the center of the clamping and positioning device.

[0004] In view of this, it is necessary to develop a positioning device for superconducting cavity surface treatment, so that the superconducting cavity can be quickly and accurately clamped in the center position of the positioning device. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this invention, when the superconducting cavity is clamped by the first clamping and positioning assembly and the second clamping and positioning assembly, the laser ranging sensors in the first and second laser ranging assemblies emit lasers to measure the distance between the two ends of the superconducting cavity. If the measured distances are equal, it indicates that the superconducting cavity is fixed in the center of the device.

During the clamping process, the laser ranging sensors measure the distance between the two ends of the superconducting cavity, allowing the operator to know whether the fixed superconducting cavity is in the center position, which facilitates the operator to make adjustments.

[0022] Example 1: Please refer to Figures 1-4 Positioning device for surface treatment of superconducting cavity;

[0023] The device includes: a fixed base 1, on which a first clamping and positioning component 2 and a second clamping and positioning component 3 are symmetrically mounted by bolts. The first clamping and positioning component 2 and the second clamping and positioning component 3 are symmetrically mounted at the center of the top of the fixed base 1. On the top of the fixed base 1, a first laser ranging component 4 and a second laser ranging component 5 are symmetrically mounted by bolts. The first laser ranging component 4 is located on one side of the first clamping and positioning component 2, and the second laser ranging component 5 is located on the other side of the second clamping and positioning component 3. The distance between the first laser ranging component 4 and the first clamping and positioning component 2 is equal to the distance between the second laser ranging component 5 and the second clamping and positioning component 3. The second laser ranging component 5 includes a mounting rod 13, a mounting platform 14, and a laser ranging sensor 15. The mounting rod 13 is fixed to the top of the fixed base 1 by screws, the mounting platform 14 is fixed to the top of the mounting rod 13, and the laser ranging sensor 15 is fixed to the top of the mounting platform 14 by screws.

[0024] The fixed base 1 provides installation positions for the first clamping and positioning component 2, the second clamping and positioning component 3, the first laser ranging component 4, and the second laser ranging component 5 at the top. The first clamping and positioning component 2 and the second clamping and positioning component 3 are used to clamp the superconducting cavity that needs surface treatment. The first laser ranging component 4 and the second laser ranging component 5 are used to position the superconducting cavity. When the superconducting cavity is clamped by the first clamping and positioning component 2 and the second clamping and positioning component 3, the laser ranging sensor 15 in the first laser ranging component 4 and the second laser ranging component 5 emits a laser to measure the distance between the two ends of the superconducting cavity. If the measured distances are equal, it indicates that the superconducting cavity is fixed in the center position of the device. If the measured distances at the two ends are different, it indicates that the fixed position of the superconducting cavity has shifted, and the operator needs to move the superconducting cavity to make it fixed in the center position of the device for use. The laser ranging sensor 15 is installed on both ends of the fixed superconducting cavity through the mounting rod 13 and the mounting platform 14 to facilitate the measurement of the distance between the two ends of the superconducting cavity.

[0025] Example 2: Please refer to Figure 1 and Figure 4 Positioning device for surface treatment of superconducting cavity;

[0026] A connecting rod 16 is installed on the top of one side of the mounting platform 14, and an indicator light 17 is installed on the top of the connecting rod 16.

[0027] The laser rangefinder 15 is connected to the data processing module of the system. After measuring the distance, the laser rangefinder 15 transmits the signal to the data processing module. After the data processing module analyzes the distance, if the distances on both sides are the same, the control module connected to the indicator light 17 controls the indicator light 17 to light up simultaneously. If the distances are different, the indicator light 17 on the side with the larger distance lights up to remind the staff that the superconducting cavity is shifted to that side, making it convenient for the staff to make adjustments.

[0028] Example 3: Please refer to Figure 1 , Figure 2 and Figure 3 Positioning device for surface treatment of superconducting cavity;

[0029] The second clamping and positioning assembly 3 includes a mounting post 6, a bottom clamping half ring 7, and a top clamping half ring 9. The mounting post 6 is fixed to the top of the fixed base 1 by bolts. The bottom clamping half ring 7 is installed at the top of the mounting post 6, and the top clamping half ring 9 is installed at the top of the bottom clamping half ring 7. A bottom clamping pad 8 is installed on the bottom inner wall of the bottom clamping half ring 7, and a top clamping pad 10 corresponding to the bottom clamping pad 8 is installed on the inner wall of the top clamping half ring 9. A threaded seat 11 is installed on the outer top of the top clamping half ring 9. A fixing screw 12 is threaded through the top of the threaded seat 11, and the thread of the fixing screw 12 passes through the outer bottom of the bottom clamping half ring 7.

[0030] When clamping the two ends of the superconducting cavity, firstly, the top clamping half-ring 9 of the first clamping positioning assembly 2 and the second clamping positioning assembly 3 is removed. The two ends of the superconducting cavity are placed inside the bottom clamping half-ring 7 and supported by the bottom clamping pad 8. Then, the top clamping half-ring 9 is installed on top of the bottom clamping half-ring 7, thereby clamping the two ends of the superconducting cavity in the middle. Then, the operator rotates the clamping fixing screw 12 so that one end of the fixing screw 12 connects with the corresponding screw hole on the bottom clamping half-ring 7. By rotating the fixing screw 12, the top clamping half-ring 9 moves downward. The top clamping pad 10 applies pressure to the top of the two ends of the superconducting cavity, thereby clamping the superconducting cavity. Since the pressure gradually increases as the fixing screw 12 rotates, the pressure can be controlled by the fixing screw 12. After the laser ranging sensor 15 measures the distance, the operator can adjust the pressure. After the adjustment is completed, continue to rotate to fully clamp and fix the cavity.

[0031] The working principle is as follows: First, the first clamping and positioning component 2 and the second clamping and positioning component 3 of the superconducting cavity are clamped and positioned. During positioning, the top clamping half ring 9 located at the top is moved downward by rotating the fixing screw 12 to apply pressure to both ends of the superconducting cavity, thereby clamping and fixing the superconducting cavity. During clamping, the top clamping pad 10 and the bottom clamping pad 8 are in contact with the superconducting cavity. The top clamping pad 10 and the bottom clamping pad 8 are rubber pads, which will not damage the superconducting cavity. During the clamping process, the laser ranging sensor 15 will measure the distance between the two ends of the superconducting cavity, so that the staff can know whether the fixed superconducting cavity is in the center position, which is convenient for the staff to make adjustments.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
