Description

Technical Field

[0001] The utility model relates to the field of target material production equipment, in particular to an auxiliary tooling for producing target materials, and in particular to an auxiliary tooling for binding rotating target materials. Background Art

[0002] When the rotating target is in use, it is necessary to bind the rotating target to the back tube to meet the installation, conductivity and heat dissipation requirements of the production equipment. The existing technology usually completes the binding of the target to the back tube by pouring solder (liquid indium or tin) into the gap between the target and the back tube and cooling it.

[0003] Before binding the rotating target and the back tube, install the back tube in a horizontal state on the mounting column of the rotating seat, use the auxiliary tooling to fix the back tube on the mounting column, then put the rotating target on the back tube, and then install the limit pad between the rotating target and the back tube to ensure that the rotating target and the back tube are coaxial. Then start the rotating seat to drive the back tube to rotate, so that the back tube is in a vertical state, and inject the solder liquid from the gap above the back tube and the rotating target. Because the gap between the back tube and the rotating target is small, bubbles are easily sealed when the solder is injected, resulting in uneven distribution of the solder.

[0004] In the prior art, in order to reduce the possibility of bubbles, bubbles in the soldering liquid are removed by vibration. When the rotating target and the backing tube are vibrated, the limit pad may fall off or shift, causing the axis of the rotating target and the backing tube to shift, and the gap between the rotating target and the backing tube to be uneven, resulting in uneven distribution of the soldering liquid, which affects the quality of the finished target.

[0022] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, they will be described in detail below in conjunction with specific examples, but the protection scope of the present invention is not limited to the following specific embodiments.

[0023] Unless otherwise defined, all professional terms used below have the same meanings as those generally understood by those skilled in the art. The professional terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the scope of protection of the present utility model.

[0024] Embodiment 1:

[0025] A rotating target material 3 binding auxiliary tooling, reference Figure 1 and Figure 2 , including a hollow cylindrical structure, the hollow cylindrical structure is formed by enclosing more than two clamping parts 1. In this embodiment, for the convenience of operation, the clamping parts 1 are set to two, and the two clamping parts 1 are symmetrically arranged. Preferably, the cross-section of the inner side of the hollow cylindrical structure is circular, and the two clamping parts 1 are enclosed to form a hollow cylindrical structure. The lower part of the inner side of the clamping part 1 is fixedly connected with a support part 1 9, and the support part 1 9 is perpendicular to the clamping part 1. The side of the support part 1 9 away from the clamping part 1 is adapted to the outer wall of the mounting column 14. The top of the clamping part 1 is fixedly connected with a support part 2 10, and the support part 2 10 is arranged perpendicular to the clamping part 1. When the two clamping parts 1 are enclosed, the two support parts 1 9 and the support part 2 10 are enclosed to form a circular ring structure. In the embodiment of the present application, the inner diameter of the circular ring is greater than the outer diameter of the back tube 4, and the outer diameter of the circular ring is smaller than the inner diameter of the back tube 4.

[0026] Reference Figure 1 The inner wall of the clamping part 1 is provided with an arc groove 8 along the circumferential direction of the rotating target 3. The arc grooves 8 on the two clamping parts 1 are connected. The clamping part 1 is provided with a liquid injection hole 6, and the liquid injection hole 6 is located in the arc groove 8. After the two clamping parts 1 are enclosed, the arc grooves 8 on the two clamping parts 1 are connected to form an annular groove. When the soldering liquid is injected into the liquid injection space 2 through the liquid injection hole 6, the soldering liquid flows along the annular groove, and overflows into the liquid injection space 2 after filling the annular groove, so that the soldering liquid can enter the gap 5 between the rotating target 3 and the back tube 4 along the circumferential direction of the rotating target 3, thereby reducing the possibility of bubbles in the soldering liquid.

[0027] When the back tube 4 and the rotating target material 3 are matched with the auxiliary tooling, the back tube 4 is located on the support part 1 9, and the contact position between the support part 1 9 and the back tube 4 is the support position 1; the rotating target material 3 is located on the support part 2 10, and the contact position between the support part 2 10 and the rotating target material 3 is the support position 2; an annular liquid injection space 2 is formed between the back tube 4 and the clamping part 1, and there is a gap 5 between the support part 2 10 and the back tube 4, and the gap 5 is the liquid injection channel 15; the arc groove 8 is connected with the gap 5 between the back tube 4 and the rotating target material 3 through the liquid injection channel 15.

[0028] Reference Figure 2The side of the support part 10 away from the clamping part 1 is adapted to the mounting column 14, increasing the contact area between the support part 10 and the mounting column 14, and improving the stability of the tooling during operation. A sealing member 11 is provided at the top of the support part 10.

[0029] Reference Figure 2 The inner wall of the clamping part 1 is fixedly connected with a sealing member 12 along the circumferential direction of the hollow cylindrical structure, and the sealing member 12 is located below the arc groove 8 and above the supporting part 9. In this embodiment, the sealing member 12 can be arranged in multiple intervals to improve the sealing effect and prevent the welding liquid from leaking from the bottom of the back tube 4.

[0030] Both the seal 11 and the seal 2 12 are sealing strips. In order to improve the sealing effect, sealing gaskets 13 can be set at both ends of the positioning part. In the soldering liquid commonly used to bind the rotating target 3 and the back tube 4, the temperature of the indium liquid is 156.6°C, and the temperature of the tin liquid is 291.9°C. The sealing strip and the sealing gasket 13 are made of elastic materials such as Teflon, LCP and high-temperature nylon that can work normally at a high temperature of 260°C. For ease of installation, a mounting groove 1 for mounting the seal 1 11 can be opened at the top of the support part 2 10, and a mounting groove 2 for mounting the seal 2 12 can be opened on the inner wall of the clamping part 1. The connection method between the seal 1 11 and the mounting groove 1, and the connection method between the seal 2 12 and the mounting groove 2 can be a common connection method such as snap-on connection and glue bonding.

[0031] Reference Figure 1 The fixing structure 7 includes fixing bolts, and threaded holes adapted to the fixing bolts are provided on both sides of the clamping portion 1. In other embodiments, the fixing structure 7 can be a commonly used connection structure such as a snap-on joint, a plug-in joint, etc.

[0032] Before binding the rotating target 3 and the back tube 4, the back tube 4 is installed on the mounting column 14 in a horizontal state, and the two clamping parts 1 are used to clamp the mounting column 14 and fix the back tube 4, and then the rotating target 3 is sleeved on the back tube 4, so that one end of the rotating target 3 abuts the supporting part 2 10, and then a limit pad is installed between the rotating target 3 and the back tube 4 to ensure that the rotating target 3 and the back tube 4 are coaxial. Start the rotating seat to drive the back tube 4 to rotate to a vertical state. At this time, the supporting part 1 9 supports the back tube 4, and the supporting part 2 10 supports the rotating target 3. Insert the solder pipe into the injection hole 6, inject the solder liquid into the injection space 2, and the solder liquid slowly overflows from the arc groove 8 and flows into the injection space 2. After filling the injection space 2, the solder liquid flows from the injection space 2 to the gap 5 between the rotating target 3 and the back tube 4, and slowly fills the solder liquid from bottom to top.

[0033] It should be noted that a common opening and closing structure such as a valve can be installed on the injection hole 6. After the solder liquid is filled, the solder liquid pipeline is drawn out, the valve is closed to prevent the solder liquid from flowing out, and the target material is left to stand until the solder liquid cools down. The solder liquid pipeline can be used to fill other target materials with solder liquid.

[0034] Embodiment 2:

[0035] The difference from Example 1 is that the two support parts 1010 are combined to form a circular ring structure, the inner side of the ring is adapted to the back tube, and a through hole is opened on the support part 1010, which serves as an injection channel 15 to connect the arc groove 8 with the gap 5 between the back tube 4 and the rotating target material 3.

[0036] In other embodiments, the cross-section of the inner side surface of the structure enclosed by the two support portions 10 can be a variety of shapes such as square, pentagon, hexagon, etc. It is only necessary to ensure that when the back tube 4 is installed between the two clamping portions 1, there is a gap (i.e., the injection channel 15) between the inner side surface of the support portion 10 and the back tube 4, so that the welding liquid can flow from the arc groove 8 to the gap 5 between the back tube 4 and the rotating target material 3, and the possibility of leakage of the welding liquid can be reduced by the provision of the sealing member 1.

[0037] Embodiment 3:

[0038] The difference from the first embodiment is that the cross section of the inner side of the hollow cylindrical structure is a square, and the two clamping parts 11 enclose to form a hollow cylindrical structure.

[0039] In other embodiments, the cross-section of the inner side of the hollow cylindrical structure can be any structure such as a rhombus, a regular pentagon, a regular hexagon, etc. It is only necessary to ensure that there is a liquid injection space 2 between the inner side of the hollow cylindrical structure and the back tube 4, so as to ensure that the welding liquid can flow from the annular groove into the gap 5 between the back tube 4 and the rotating target material 3, thereby realizing liquid injection from bottom to top and reducing the possibility of bubbles in the welding liquid.
