[0024] like Figure 1 As shown, an embodiment of the present application provides a cathode rod auxiliary installation mechanism 100, which is primarily used to assist in the horizontal insertion of a cathode rod in an electrochemical polishing device into a superconducting radio frequency cavity, and to prevent the cathode rod from contacting and damaging the inner surface of the superconducting radio frequency cavity during insertion. The cathode rod auxiliary installation mechanism 100 includes a cathode rod docking module 110 and a rigid guide rod docking module 120, which are spaced apart along a first direction D1. The superconducting radio frequency cavity is disposed between the cathode rod docking module 110 and the rigid guide rod docking module 120.

[0025] It should be noted that the first direction D1 is parallel to the extension direction of the cathode rod 200, the second direction D2 is the height direction perpendicular to the ground, and the third direction D3 is the width direction of the cathode rod docking module 110 or the hard guide rod docking module 120. The first direction D1, the second direction D2 and the third direction D3 are perpendicular to each other. For example, Figure 1 In the embodiment, the first direction D1 is the left-right direction, the second direction D2 is the up-down direction, and the third direction D3 is the front-back direction.

[0026] The cathode rod docking module 110 is used to support the cathode rod 200 and drive the cathode rod 200 to move toward the direction close to the hard guide rod docking module 120; the hard guide rod docking module 120 is used to drive the hard guide rod 122 to move toward the direction close to the cathode rod docking module 110. After completing the docking of the hard guide rod 122 and the cathode rod 200, the hard guide rod 122 assists the cathode rod 200 to safely pass through the superconducting radio frequency cavity.

[0027] To reduce the footprint of the cathode rod auxiliary installation mechanism 100, a cathode rod docking module 110 and a rigid guide rod docking module 120 are respectively arranged on both sides of the superconducting RF cavity. In the first direction D1, dynamic seals are provided at both ends of the superconducting RF cavity along the first direction D1, one dynamic seal facing the cathode rod 200 and the other dynamic seal facing the rigid guide rod 122. The dynamic seals are provided with insertion holes connected along the first direction D1. The rigid guide rod 122 is inserted into the superconducting RF cavity through the corresponding dynamic seal and exits from the insertion hole of the opposite dynamic seal. The docking operation of the cathode rod 200 and the rigid guide rod 122 is completed outside the superconducting RF cavity.

[0028] The cathode rod 200 is a hollow rod made of a material with excellent electrical conductivity and high-temperature resistance, such as aluminum. It is a key component used to support the cathode and provide electrical connections. It secures the cathode, maintaining a precise distance between the cathode and the anode (superconducting RF cavity), and provides a stable current input to the cathode, enabling electrochemical polishing.

[0029] The hard guide rod 122 is made of a material with high strength and not easy to deform, such as carbon fiber. The end of the hard guide rod 122 close to the cathode rod docking module 110 is tapered (such as Figure 8 ), it is convenient to insert the end of the hard guide rod 122 into the end of the cathode rod 200 and dock with the cathode rod 200.

[0030] In one embodiment, the cathode rod docking module 110 includes a first guide rail frame 111 and a first guide rail 112 provided on the first guide rail frame 111, a cathode rod fixing assembly 113 and a support assembly 114; the rigid guide rod docking module 120 includes a second guide rail frame 121 and a second guide rail 123 provided on the second guide rail frame 121, a rigid guide rod fixing assembly 124 and a rigid guide rod 122, and the first guide rail frame 111 and the second guide rail 123 are respectively arranged at intervals from the superconducting radio frequency cavity.

[0031] The first guide rail 112 and the second guide rail 123 are spaced apart and arranged on the same straight line, so that the cathode rod 200 and the hard guide rod 122 move on the same straight line, thereby improving the docking efficiency of the cathode rod 200 and the hard guide rod 122.

[0032] The cathode rod fixing assembly 113 and the support assembly 114 are slidably mounted on the first guide rail 112, with the support assembly 114 located on a side of the cathode rod fixing assembly 113 away from the second guide rail 123. The cathode rod fixing assembly 113 secures the cathode rod 200 and provides thrust for the cathode rod 200 to move in the first direction D1, while the support assembly 114 supports the cathode rod 200. This significantly reduces the end droop of the cathode rod 200 due to gravity, allowing the cathode rod 200 to pass through the superconducting RF cavity in a well-aligned configuration.

[0033] The rigid guide rod 122 is connected to the rigid guide rod fixing assembly 124 and is arranged parallel to the second guide rail 123. The rigid guide rod fixing assembly 124 is slidably arranged on the second guide rail 123. Before the cathode rod 200 is inserted into the superconducting RF cavity, the rigid guide rod 122 is moved to the peripheral side close to the superconducting RF cavity by the rigid guide rod fixing assembly 124, so that the rigid guide rod 122 is inserted into the superconducting RF cavity through the corresponding dynamic seal and passes through the insertion hole of the dynamic seal on the opposite side, so that the end of the rigid guide rod 122 is close to the cathode rod 200, and then the cathode rod fixing assembly 113 and the support assembly 114 are moved to insert the end of the rigid guide rod 122 into the cathode rod 200 to complete the docking. After docking, the end of the cathode rod 200 is fixed by the hard guide rod 122, so that the cathode rod 200 as a whole maintains a high degree of alignment when entering and exiting the superconducting RF cavity, avoiding the cathode rod 200 from colliding with the inner surface of the superconducting RF cavity due to gravity deformation.

[0034] In some embodiments, as Figure 1 As shown, the first guide rail 112 and the second guide rail 123 both extend along the first direction D1, so that the cathode rod 200 and the hard guide rod 122 both move toward each other along the first direction D1, thereby improving docking efficiency.

[0035] like Figure 2 As shown, the support assembly 114 includes a support member 1141 , a moving member 1142 and a first sliding seat 1143 .

[0036] The first sliding seat 1143 is slidably arranged on the first guide rail 112. The first sliding seat 1143 is used to enable the support assembly 114 to move along the first guide rail 112 as a whole, so as to better support the cathode rod 200. For example, when the cathode rod 200 is not inserted into the superconducting radio frequency cavity and the cathode rod 200 is stationary on the first guide rail 112, the support assembly 114 is moved to the middle area of ​​the cathode rod 200 to serve as a placement rack for the cathode rod 200, thereby reducing deformation of the cathode rod 200; when the cathode rod 200 needs to be inserted into the superconducting radio frequency cavity, the support assembly 114 is moved to the end of the first guide rail 112 near the second guide rail 123, and the end of the cathode rod 200 is straightened so that the part to be inserted into the cathode rod 200 is inserted into the cavity in a well-aligned form, thereby improving docking efficiency.

[0037] It should be noted that after the cathode rod 200 and the hard guide rod 122 are docked, the cathode rod fixing assembly 113 continues to push toward the second guide rail 123, so that the end of the cathode rod 200 passes through the superconducting radio frequency cavity. Figure 1 The cathode rod fixing assembly 113 and the support assembly 114 gradually become smaller, until the support member 1141 blocks the forward movement of the cathode rod fixing assembly 113 , shortening the moving stroke of the cathode rod fixing assembly 113 on the first guide rail 112 .

[0038] In response to the above issues, please refer to Figure 2 and Figure 3 A moving member 1142 is movably connected to the first sliding seat 1143 so that the moving member 1142 moves relative to the first sliding seat 1143 along the second direction D2. The support member 1141 is connected to the moving member 1142. The moving member 1142 drives the support member 1141 to move along the second direction D2, thereby avoiding the movement of the cathode rod fixing assembly 113, extending the movement stroke of the cathode rod fixing assembly 113 on the first guide rail 112, and avoiding interference between the support member 1141 and the cathode rod fixing assembly 113.

[0039] In some embodiments, as Figure 2 and Figure 3 As shown, the moving member 1142 includes a third guide rail 11421 , a mounting plate 11422 and a latch 11424 .

[0040] Among them, the third guide rail 11421 is arranged on the side of the first sliding seat 1143 away from the first guide rail 112, the third guide rail 11421 extends along the second direction D2, the mounting plate 11422 is slidably arranged on the third guide rail 11421, and the support member 1141 is connected to the side of the mounting plate 11422 away from the first guide rail 112.

[0041] The mounting plate 11422 is provided with a first through hole 11423 that is connected along the third direction D3. A limiting hole 11431 is provided on a side of the first sliding seat 1143 that is away from the first guide rail 112. A latch 11424 is movably inserted into the first through hole 11423, allowing the latch 11424 to be inserted into or removed from the limiting hole 11431. When the latch 11424 is inserted into the first through hole 11423 and the limiting hole 11431, the latch 11424 retains freedom only in the third direction D3 and is constrained and fixed in both the first direction D1 and the second direction D2, thereby securing the mounting plate 11422 to the first sliding seat 1143. The support member 1141 is positioned entirely below the cathode rod 200 to support the cathode rod 200.

[0042] When the cathode rod fixing assembly 113 needs to be avoided, the pin 11424 is pulled out of the limiting hole 11431, so that the mounting plate 11422 and the first sliding seat 1143 are staggered in the second direction D2, and the support member 1141 deviates from the first guide rail 112, leaving space for the cathode rod fixing assembly 113 to move forward.

[0043] In some embodiments, a support groove 11411 is formed on one side of the support member 1141 away from the first guide rail 112. Figure 2 As shown, the support member 1141 is roughly rectangular, including a first connecting plate 11412 arranged along the first direction D1, two second connecting plates 11413 arranged along the second direction D2 and a support plate 11414 arranged along the first direction D1, and the support groove 11411 is provided on the support plate 11414.

[0044] A sliding groove 11415 is formed on one side of the second connecting plate 11413 close to the first connecting plate 11412 and extends through the third direction D3. The sliding groove 11415 facilitates leveling of the support plate 11414 so that the support groove 11411 is parallel to the first direction D1.

[0045] The support member 1141 further includes two connecting bolts 11416 . The first connecting plate 11412 and the second connecting plate 11413 are formed with overlapping holes. The connecting bolts 11416 are passed through the overlapping holes to fix the first connecting plate 11412 and the second connecting plate 11413 .

[0046] In one embodiment, if Figure 2 As shown, the support groove 11411 penetrates the support plate 11414 along the first direction D1. The support groove 11411 has an opening facing away from the first guide rail 112, so that the cross-section of the support groove 11411 is inverted triangular, semicircular, or U-shaped. Such a concave shape can limit the freedom of the cathode rod 200, making it less likely to fall from the support plate 11414, and also ensure smooth movement of the cathode rod 200 in the first direction D1.

[0047] In some embodiments, the support assembly 114 further includes a first longitudinal moving member 1144 and a first transverse moving member 1145 .

[0048] In one embodiment, if Figure 2As shown, the first longitudinal moving member 1144 is connected to the side of the mounting plate 11422 away from the first guide rail 112, and can move along the third direction D3 relative to the mounting plate 11422, the first transverse moving member 1145 is connected to the first longitudinal moving member 1144, and can move along the second direction D2 relative to the mounting plate 11422, and the support member 1141 is connected to the first transverse moving member 1145, so that the support member 1141 can realize movement in the first direction D1, the third direction D3 and the second direction D2 through the first sliding seat 1143, the first longitudinal moving member 1144 and the first transverse moving member 1145.

[0049] In one embodiment, Figure 4 As shown, the first longitudinal moving member 1144 includes a driving rod 11441, a first bottom plate 11442, a top plate 11443 and a cross rod 11444. The first bottom plate 11442 is set on the mounting plate 11422, the top plate 11443 is set above the first bottom plate 11442 at intervals, and the cross rod 11444 is formed by two rods cross-hinged. The cross rod 11444 has four corners, Figure 4 In the embodiment, the right corner of the cross bar 11444 is hinged to the first bottom plate 11442 or the top plate 11443, and the left corner of the cross bar 11444 is hinged to the driving rod 11441. The driving rod 11441 drives the cross bar 11444 to move along the second direction D2 to increase or decrease the distance between the top plate 11443 and the first bottom plate 11442, thereby adjusting the position of the support member 1141 in the third direction D3.

[0050] In one embodiment, Figure 5 As shown, the first transverse moving member 1145 includes a second base plate 11451, a screw rod 11452, and a sleeve 11453. A guide rail is provided on the second base plate 11451. The screw rod 11452 is disposed on the second base plate 11451 and extends in the second direction D2. The sleeve 11453 is sleeved on the screw rod 11452 and slides on the guide rail. Forward and reverse rotation of the screw rod 11452 drives the sleeve 11453 to move in the second direction D2. The support member 1141 is fixedly connected to the sleeve 11453, enabling adjustment of the support member 1141 in the second direction D2.

[0051] In some embodiments, as Figure 6 As shown, the cathode rod fixing assembly 113 includes an extension plate 1131 , a first clamping jaw 1132 , a second sliding seat 1133 , a second longitudinal moving member 1134 and a second transverse moving member 1135 .

[0052] In one embodiment, Figure 2 and Figure 6As shown, the second longitudinal moving member 1134 has the same structure as the first longitudinal moving member 1144 , and the second transverse moving member 1135 has the same structure as the first transverse moving member 1145 , which simplifies the structure and reduces the cost.

[0053] like Figure 6 The extension plate 1131 is strip-shaped and extends along the first direction D1. The second transverse moving member 1135 is connected to one end of the extension plate 1131. The first clamping jaw 1132 is connected to the other end of the extension plate 1131. The first clamping jaw 1132 is arranged close to the supporting assembly 114.

[0054] The first clamping jaw 1132 is used to clamp the end of the cathode rod 200. The first clamping jaw 1132 includes two clamping blocks that open and close along the second direction D2. In one embodiment, the clamping blocks and the aforementioned support plate 11414 are made of plastic, allowing the first clamping jaw 1132 to more stably clamp the cathode rod 200.

[0055] like Figure 6 As shown, the second sliding seat 1133 is slidably arranged on the first guide rail 112, the second longitudinal moving member 1134 is connected to the second sliding seat 1133 and can move relative to the second sliding seat 1133 along the third direction D3, the second transverse moving member 1135 is connected to the second longitudinal moving member 1134 and can move relative to the second sliding seat 1133 along the second direction D2, and the first clamping jaw 1132 is connected to the second transverse moving member 1135, so that the first clamping jaw 1132 can move along the first direction D1, the third direction D3 and the second direction D2 through the second sliding seat 1133, the second longitudinal moving member 1134 and the second transverse moving member 1135. Generally, as Figure 7 As shown, during the docking installation of the cathode rod 200 and the superconducting RF cavity, an end cap 300 is also mounted on the end of the cathode rod 200 away from the rigid guide rod 122. The end cap 300 is located on the side of the first clamping jaw 1132 near the support member 1141 and is used to cover the outer surface of the dynamic seal of the superconducting RF cavity. Therefore, after the end of the cathode rod 200 passes through the superconducting RF cavity, it still needs to move forward a certain distance to allow the end cap 300 to be installed on the outer surface of the dynamic seal.

[0056] In view of the above situation, the present application moves the support member 1141 out of the first guide rail 112, thereby reserving a sufficiently long distance so that the end cover 300 can cover the outside of the dynamic seal.

[0057] Specifically, such as Figure 1 、 Figure 2 and Figure 6As shown, when the support member 1141 blocks the forward movement of the first clamping jaw 1132, the first longitudinal movable member 1144 is first adjusted to lower the support member 1141, thereby separating the cathode rod 200 from the support member 1141. The latch 11424 is then pulled out of the limiting hole 11431, allowing the mounting plate 11422 to move in the second direction D2. This allows the mounting plate 11422 and the support member 1141 disposed above the mounting plate 11422 to at least partially move to an edge extending beyond the mounting plate 11422, thereby offsetting the support member 1141 and the first clamping jaw 1132 in the second direction D2. At this point, the second sliding seat 1133 is further pushed, causing the extension plate 1131 and the first clamping jaw 1132 to pass above the first sliding seat 1143, thereby extending the travel of the cathode rod 200 and allowing the end cap 300 to cover the outside of the dynamic seal.

[0058] In one embodiment, referring to Figure 6 and Figure 11 , Figure 6 The number of the extension plate 1131 is one, and the length of the extension plate 1131 is fixed. Figure 11 The extension plate 1131 shown in the figure is a telescopic structure. The length of the extension plate 1131 in the first direction D1 can be changed to extend the movable stroke of the cathode rod 200 so that the end cover 300 can cover the outer side of the dynamic seal.

[0059] In some embodiments, as Figure 8 and Figure 9 As shown, the rigid guide rod fixing assembly 124 includes a telescopic guide rail 1241 and two movable members 1242 . The two movable members 1242 are respectively slidably disposed on the telescopic guide rail 1241 . The movable members 1242 are used to fix the rigid guide rod 122 .

[0060] It should be noted that the electrochemical polishing device for the superconducting RF cavity includes a rotation mechanism that drives the superconducting RF cavity to rotate within a plane perpendicular to the first direction D1. Therefore, sufficient rotational space must be reserved during the rotation of the superconducting RF cavity. When the cathode rod 200 is docked, the rigid guide rod fixing assembly 124 is brought closer to the superconducting RF cavity, and the end of the rigid guide rod 122 is brought closer to the cathode rod 200 in preparation for docking.

[0061] In response to the above requirements, such as Figure 9As shown, the telescopic guide rail 1241 is slidably disposed on the second guide rail 123 and extends at least partially beyond the end of the second guide rail 123 near the first guide rail 112. Thus, when rotation is required, the telescopic guide rail 1241 is completely moved onto the second guide rail 123, effectively folding the second guide rail 123 to create space. When docking is required, the telescopic guide rail 1241 extends beyond the second guide rail 123, effectively extending the second guide rail 123, allowing the two movable members 1242 to be closer to the superconducting RF cavity and the rigid guide rod 122 to be closer to the cathode rod 200 before docking, thereby improving docking efficiency.

[0062] It can be understood that when rotation is required, the first clamping jaw 1132 and the support member 1141 are also moved away from the second guide rail 123, so that the first clamping jaw 1132 and the support member 1141 are both accommodated above the first guide rail 112, forming an avoidance and leaving rotation space.

[0063] In some embodiments, as Figure 8 As shown, the movable member 1242 includes a second clamping jaw 12421 , a third sliding seat 12422 , a third longitudinal moving member 12423 and a third transverse moving member 12424 .

[0064] In one embodiment, if Figure 8 The third longitudinal moving member 12423 has the same structure as the first longitudinal moving member 1144, and the third transverse moving member 12424 has the same structure as the first transverse moving member 1145, which simplifies the structure and reduces costs.

[0065] The third sliding seat 12422, the third longitudinal moving member 12423, the third transverse moving member 12424, and the second clamping jaw 12421 are connected in sequence. The third sliding seat 12422 is also slidably arranged on the second guide rail 123. The third transverse moving member 12424 drives the third sliding seat 12422 to move in the second direction D2 relative to the third sliding seat 12422. The third longitudinal moving member 12423 can move in the third direction D3 relative to the third sliding seat 12422. The hard guide rod 122 is connected to the second clamping jaw 12421. The second clamping jaw 12421 can move in the first direction D1, the third direction D3, and the second direction D2 through the third sliding seat 12422, the third longitudinal moving member 12423, and the third transverse moving member 12424.

[0066] It should be noted that by providing the two second clamping jaws 12421 , the connection of the rigid guide rod 122 is made more stable, and the rigid guide rod 122 can better maintain the aligned posture extending along the first direction D1 , thereby providing a stronger supporting force.

[0067] In one embodiment, the movable member 1242 adjacent to the first guide rail 112 may be replaced with the support assembly 114 .

[0068] In one embodiment, Figure 10 and Figure 12 As shown, Figure 12 Shown in Figure 1 The movable parts 1242 of different structures are shown. Figure 12 As shown, the movable member 1242 near the first guide rail 112 includes a vertical plate 12427 and a horizontal clamping plate 12428. The vertical plate 12427 extends along the third direction D3 and is connected to the third sliding seat 12422. The horizontal clamping plate 12428 is connected to the end of the vertical plate 12427 away from the third sliding seat 12422. The horizontal clamping plate 12428 extends along the first direction D1 and defines a second through hole 12429 that communicates along the first direction D1. The provision of the horizontal clamping plate 12428 increases the support force for the rigid guide rod 122, making the rigid guide rod 122 more stable during movement and less prone to displacement.

[0069] like Figure 8 As shown, the second clamping jaw 12421 includes a lower clamping plate 12425 and an upper clamping plate 12426. The lower clamping plate 12425 is connected to the third transverse moving member 12424, and the upper clamping plate 12426 is openably connected to the lower clamping plate 12425. When the upper clamping plate 12426 and the lower clamping plate 12425 are closed, a clamping hole is formed, and the end of the hard guide rod 122 is passed through and fixed to the clamping hole.

[0070] like Figure 10 and Figure 12 As shown, the cathode rod auxiliary installation mechanism 100 further includes two guide members 130. The guide members 130 straighten and guide the rod body that is about to enter the RF superconducting cavity, thereby improving the coaxiality of the cathode rod 200, the hard guide rod 122 and the two insertion holes on the RF superconducting cavity.

[0071] The guide member 130 is detachably connected to the electrochemical polishing device. One guide member 130 is arranged on the side of the electrochemical polishing device close to the first guide rail 112, and the other guide member 130 is arranged on the side of the electrochemical polishing device close to the second guide rail 123. The guide member 130 is provided with a guide hole 131 connected along the first direction D1, and the hard guide rod 122 or the cathode rod 200 is passed through the guide hole 131.

[0072] See Figure 1 The installation process of inserting the cathode rod 200 into the superconducting radio frequency cavity is as follows: Adjust the posture of the superconducting radio frequency cavity so that the insertion holes on the two dynamic seals are connected along the first direction D1; Connect the hard guide rod 122 to the second clamping jaw 12421 , connect the end of the cathode rod 200 to the first clamping jaw 1132 , and place the rod body on the support groove 11411 of the support member 1141 ; Adjust the first transverse moving member 1145, the first longitudinal moving member 1144, the second transverse moving member 1135, the second longitudinal moving member 1134, the third transverse moving member 12424, and the third longitudinal moving member 12423 so that the axis of the hard guide rod 122, the axis of the insertion hole, and the axis of the cathode rod 200 are aligned. Move the movable member 1242 along the second guide rail 123 so that the end of the rigid guide rod 122 passes into and out of the superconducting radio frequency cavity. The movable member 1242 is as close to the superconducting radio frequency cavity as possible so that the end of the rigid guide rod 122 is closer to the cathode rod 200. Move the support member 1141 to the end of the first guide rail 112, and then move the first clamping jaw 1132 to move the cathode rod 200 toward the hard guide rod 122, so that the tapered end of the hard guide rod 122 is inserted into the cathode rod 200 to complete the docking; Continue to push the first clamping jaw 1132 toward the second guide rail 123, so that the end of the cathode rod 200 passes through the adjacent dynamic seal and passes through the other dynamic seal; The first clamping jaw 1132 is continuously pushed in the direction close to the second guide rail 123 so that the end cover 300 on the cathode rod 200 is connected to the outer side surface of the dynamic seal, and the installation of the cathode rod 200 is completed.

[0073] When the cathode rod 200 penetrates the dynamic seal until the end cover 300 on the cathode rod 200 is connected to the outer side of the dynamic seal, the support member 1141 prevents the first clamping jaw 1132 from continuing to advance in the direction close to the second guide rail 123, the first longitudinal moving member 1144 is adjusted to lower the support member 1141 to separate the cathode rod 200 and the support member 1141, and then the pin 11424 is pulled up to make the pin 11424 leave the limiting hole 11431, and the pin 11424 is pulled along the second direction D2 to stagger the mounting plate 11422 and the support member 1141 with the first guide rail 112 in the second direction D2, so that the first clamping jaw 1132 drives the cathode rod 200 to continue to advance in the direction close to the second guide rail 123.
