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 fills solder (liquid indium or tin) into the gap between the target and the back tube, cools it, and achieves the binding of the target and the back tube.

[0003] During the binding process, the rotating target is easily moved due to external forces, the axis lines of the rotating target and the back tube are offset, and the spacing between the rotating target and the back tube is uneven, resulting in uneven distribution of solder, which affects the binding effect of the target.

[0004] CN214161369U discloses a rotating target binding and fixing device, including a bottom plate, two fixing plates fixedly connected to the upper wall of the bottom plate, a back tube fixedly connected to the upper wall of the bottom plate, a rotating target material is arranged above the bottom plate, a liquid injection tube is fixedly connected to the upper wall of the bottom plate, and a clamping mechanism for clamping the rotating target material is arranged above the bottom plate, the clamping mechanism includes two clamping plates, and the side walls of the two clamping plates are provided with arc surfaces. When using the above device, it is necessary to first move the back tube to the clamping area of ​​the bottom plate, and then sleeve the rotating target material on the back tube. The clamping mechanism can only position the rotating target material, but does not limit the back tube, and cannot ensure that the rotating target material and the back tube are concentric, that is, it cannot solve the problem of uneven distribution of solder.

[0007] Preferably, the number of the positioning portions is two; the two positioning portions are symmetrically arranged.

[0008] Preferably, the width of the step is equal to the difference between the outer diameters of the rotary target and the backing tube.

[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 meaning 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 binding auxiliary tooling, referring to Figure 1 , comprising two or more positioning parts 1, the lower part of the positioning part 1 is fixedly connected with a step 2, the step 2 is perpendicular to the positioning part 1, the width of the step 2 is equal to the difference in the outer diameter of the rotating target and the back tube, and the two or more positioning parts 1 are enclosed to position the rotating target. The inner side surface formed by the two or more positioning parts 1 is a first positioning surface 4, and the side of the step 2 away from the positioning part 1 is a second positioning surface 5, and the inscribed circle of the cross section of the first positioning surface 4 and the second positioning surface 5 is concentric.

[0026] In this embodiment, for the convenience of operation, two positioning parts 1 are provided, and the two positioning parts 1 can enclose a circular ring structure, and the cross-section of the first positioning surface 4 and the second positioning surface 5 is circular. The first positioning surface 4 is adapted to the outer surface of the rotating target, and the second positioning surface 5 is adapted to the outer surface of the back tube, so as to increase the contact area between the positioning part 1 and the rotating target, and between the positioning part 1 and the back tube, and improve the positioning effect.

[0027] Both ends of the positioning part 1 are provided with mounting grooves 6, and spring washers 7 are fixedly connected in the mounting grooves 6. It should be noted that the spring washers 7 can be block-shaped or strip-shaped washers made of elastic material; the connection methods of the spring washers 7 include but are not limited to common matching methods such as glue bonding, screw connection, and clamping.

[0028] A seal is fixedly connected to the top surface of the step 2. The seal is a sealing strip, which is arranged along the circumferential direction of the rotating target. When the bottom of the rotating target abuts against the step 2, the sealing strip is located between the rotating target and the step 2, thereby enhancing the sealing and reducing the possibility of leakage of the welding liquid.

[0029] In the soldering liquid commonly used for binding the rotating target and the back tube, the temperature of the indium liquid is 156.6°C, the temperature of the tin liquid is 231.9°C, and the spring pad 7 and the sealing ring are made of elastic materials such as Teflon, PP, LCP and high-temperature nylon that can work normally at a high temperature of 260°C.

[0030] Two adjacent positioning parts 1 are fixed by a fixing structure, and a fixing structure 3 is provided to make the positioning part 1 and the back tube have an interference fit. The fixing structure 3 includes a fixing screw, and threaded holes adapted to the fixing screw are provided on both sides of the positioning part 1.

[0031] In other embodiments, the fixing structure 3 may be a commonly used connection structure such as a snap-on connector, a plug-in connector, etc.

[0032] Before binding the rotating target and the back tube, first make the back tube horizontal, then put the rotating target on the designated position of the back tube, and then install the positioning part 1 on the bottom end of the rotating target, and then use the fixing structure 3 to fix the positioning part 1 on the back tube. The two positioning parts 1 are fixed on the back tube by the action of friction, and the two positioning parts clamp the rotating target. At this time, the first positioning surface 4 abuts against the outer wall of the rotating target, the second positioning surface 5 abuts against the outer wall of the back tube, and the back tube and the rotating target are coaxial. Before injecting the welding liquid between the back tube and the rotating target, rotate the back tube so that the back tube is in a vertical state, and the bottom of the rotating target is located on the step 2, and the step 2 supports the rotating target.

[0033] The first positioning surface 4 and the second positioning surface 5 cooperate to ensure that the rotating target and the back tube are coaxial, so that the welding liquid is evenly distributed between the rotating target and the back tube, thereby improving the welding effect. At the same time, the installation position of the rotating target can be adjusted according to actual conditions. The installation position of the rotating target can be adjusted by simply adjusting the installation position of the auxiliary tooling on the back tube.

[0034] Embodiment 2:

[0035] The difference from the first embodiment is that the cross-sections of the first positioning surface 4 and the second positioning surface 5 are elliptical, and after the two positioning parts 1 are enclosed, the inscribed circle of the first positioning surface 4 and the inscribed circle of the second positioning surface 5 are concentric.

[0036] In other embodiments, the cross-sections of the first positioning surface 4 and the second positioning surface 5 may be square, regular hexagonal, or other structures. It is only necessary to ensure that the inscribed circles of the first positioning surface 4 and the second positioning surface 5 are concentric to ensure that the rotating target and the back tube are coaxial after positioning, and the gaps between the rotating target and the back tube are equal at all locations, so that the welding liquid is evenly distributed between the rotating target and the back tube.

[0037] Embodiment 3:

[0038] The difference from Example 1 is that, in order to further improve the positioning effect, a first anti-skid pad can be provided on the first positioning surface 4, and a second anti-skid pad can be provided on the second positioning surface 5. Anti-skid pad installation grooves are provided on the first positioning surface 4 and the second positioning surface 5, and the first anti-skid pad is installed in the anti-skid pad installation groove on the first positioning surface 4, and the second anti-skid pad is installed in the anti-skid pad installation groove on the second positioning surface 5, and the surface of the anti-skid pad is provided with anti-skid patterns.
