Description

Technical Field

[0001] This invention relates to the field of electron accelerator assembly, and more particularly to an electron accelerator tube bonding fixture. Background Technology

[0002] The accelerating tube is the core component of an electron accelerator, mainly used to accelerate electrons emitted from the electron gun. Currently, the accelerating tube is mainly made of multiple ceramic rings and multiple electrode plates stacked together. Depending on the requirements, the ceramic rings and electrode plates are fixed by two methods: welding and bonding. The bonding method uses bonding fixtures.

[0003] For example, CN108747910B discloses an electron accelerator tube bonding fixture for fixing and pressing the bonded ceramic ring and electrode sheet. It includes an upper mounting plate, a lower mounting plate, and support columns located between the upper and lower mounting plates. There are at least two support columns. A pressing device is provided between the upper and lower mounting plates. A positioning element for positioning the ceramic ring and a fixing element for fixing the movable ceramic ring are provided between the upper and lower mounting plates. The ceramic ring is fixed in its radial direction by the fixing element with the positioning element as a reference.

[0004] This patent uses positioning components to position ceramic rings or electrode sheets. When assembling the accelerator tube, if adhesive is applied to the tooling, the uniformity of the adhesive application cannot be ensured. Furthermore, since the accelerator tube is made of multiple ceramic rings and multiple electrode sheets stacked together, the tooling of this patent can only apply adhesive layer by layer upwards. There is a time difference in the bonding of the upper and lower layers of adhesive, which affects the bonding quality. If adhesive is applied first and then installed on the tooling, the assembly efficiency is affected, and it is easy to cause the ceramic rings and electrode sheets to shift. Summary of the Invention

[0005] In view of this, the purpose of this invention is to provide an electron accelerator tube bonding fixture to achieve bonding at the same time, thereby improving the bonding efficiency and quality of the accelerator tubes.

[0006] To achieve the above technical objectives, the present invention provides a fixture for bonding electron accelerator tubes:

[0007] It includes a clamping part and a positioning part. The positioning part includes: a ceramic ring positioning assembly, which is assembled on the clamping part and is used to position the ceramic ring; an electrode plate positioning assembly, which is distributed on both sides of the ceramic ring positioning assembly and is used to position the electrode plate; and an auxiliary assembly, which is used to assist in positioning the ceramic ring and to apply adhesive to the ceramic ring.

[0008] Preferably, the ceramic ring positioning assembly includes: two limiting plates; a guide rod with both ends fixedly connected to the two limiting plates respectively, and positioning blocks for positioning the ceramic ring are uniformly sleeved on the outer surface of the guide rod; and a spring sleeved on the guide rod, with the spring located between adjacent positioning blocks.

[0009] Preferably, the ceramic ring positioning assembly further includes: a drive rod, the end of which is rotatably connected to the limiting plate; a drive wheel is provided through the outer surface of the positioning block; the drive wheel is rotatably connected to the positioning block; and the outer surface of the drive rod abuts against the drive wheel; and a motor, fixed on the limiting plate, with the output end of the motor fixedly connected to the drive rod.

[0010] Preferably, the electrode positioning assembly includes: a fixing block fixed to a limiting plate; a connecting frame with its end hinged to the fixing block, and a torsion spring fixed at the hinge point between the connecting frame and the fixing block, the torsion spring being used to provide radial elastic force to the connecting frame; and a positioning rod with its end rotatably connected to the connecting frame.

[0011] Preferably, the auxiliary component includes: a connecting seat, fixedly connected to the outer surface of the limiting plate; a handrail, fixedly connected to the connecting seat; an auxiliary frame, fixed to the end of the handrail; and a conduit, the end of which passes through the auxiliary frame and is fixed, and the interior of the conduit communicates with the inner cavity of the auxiliary frame.

[0012] Preferably, the outer surface of the auxiliary frame is uniformly provided with ceramic ring positioning grooves and electrode plate positioning grooves, which are used to assist in positioning the ceramic ring and the electrode plate, respectively, and the outer surface of the ceramic ring positioning groove is provided with an adhesive outlet.

[0013] Preferably, a dispensing nozzle is embedded inside the dispensing port.

[0014] Preferably, the clamping part includes: a first fixed seat; a second fixed seat; a fixed rod, both ends of which are fixedly connected to the first fixed seat and the second fixed seat respectively; a movable pressure plate, which is slidably connected to the second fixed seat; a driving member, which is fixed on the second fixed seat, and the output end of the driving member is fixedly connected to the outer surface of the movable pressure plate; and a fixed pressure plate, which is slidably connected to the first fixed seat.

[0016] Preferably, a first rubber pad and a second rubber pad are uniformly fixed on the outer surface of the movable pressure plate, and the second rubber pad abuts against the outer surface of the positioning block.

[0017] As can be seen from the above technical solutions, this application has the following beneficial effects:

[0018] 1: By assembling auxiliary components on the ceramic ring positioning assembly, the ceramic ring can be positioned in an auxiliary manner, and glue can be applied to the ceramic ring at the same time. Each positioning block is rotatably connected to a drive wheel, which drives the ceramic ring to rotate uniformly, so that each ceramic ring can be evenly coated with glue at the same time.

[0032] The following description is exemplary in nature and is not intended to limit the scope, application, or use of this disclosure. It should be understood that in all these figures, the same or similar reference numerals indicate the same or similar parts and features. The figures are merely schematic representations of the concept and principles of embodiments of this disclosure and do not necessarily show the specific dimensions and scale of the various embodiments of this disclosure. Certain details or structures of embodiments of this disclosure may be exaggerated in particular portions of certain figures. Example 1

[0033] See Figure 1 and Figure 2 As shown, an electron accelerator tube bonding fixture includes a clamping part 1 and a positioning part 2. The positioning part 2 is used to position the ceramic ring and the electrode sheet. After applying adhesive to the ceramic ring, the clamping part 1 clamps the ceramic ring and the electrode sheet to complete the bonding. The positioning part 2 is independent of the clamping part 1, which is intended to facilitate the replacement of the positioning part 2 according to different specifications of accelerator tubes.

[0034] For details, please refer to Figure 2 As shown, the positioning part 2 includes a ceramic ring positioning assembly 21, an electrode plate positioning assembly 22, and an auxiliary assembly 23. The ceramic ring positioning assembly 21 is mounted on the clamping part 1 and is used to position the ceramic ring. The electrode plate positioning assembly 22 is distributed on both sides of the ceramic ring positioning assembly 21 and is used to position the electrode plate. The auxiliary assembly 23 is mounted on the ceramic ring positioning assembly 21 and is used to assist in positioning the ceramic ring and to apply adhesive to the ceramic ring.

[0035] For more details, please refer to Figure 2 , Figure 3 and Figure 6As shown, the ceramic ring positioning assembly 21 includes a limiting plate 211, a guide rod 212, a positioning block 213, a spring 214, a drive rod 215, and a motor 216. Two limiting plates 211 are provided, which are respectively fixed to the two ends of the guide rod 212. The outer surface of the guide rod 212 is uniformly fitted with positioning blocks 213 for positioning the ceramic ring. The surface shape of the positioning block 213 depends on the shape of the ceramic ring. The number of guide rods 212 depends on the number of ceramic rings in the acceleration tube. The spring 214 is fitted on the guide rod 212 and is located between adjacent positioning blocks 213. The spring 214 is used to provide a restoring force for the positioning block 213. For example, the ceramic ring is placed on the positioning block 213, and the electrode sheet is placed between adjacent ceramic rings. By applying pressure through the clamping part 1, multiple ceramic rings and positioning blocks 213 can be brought closer to each other, thereby making the ceramic ring and the electrode sheet adhere.

[0036] It is worth mentioning that the spring 214 is embedded in the positioning block 213, ensuring that the spring 214 has room to contract.

[0037] See Figure 3 As shown, the ceramic ring positioning assembly 21 also includes a drive rod 215 and a motor 216. The end of the drive rod 215 is rotatably connected to the limiting plate 211. A drive wheel 2131 is provided through the outer surface of the positioning block 213 to increase the friction between the surface of the drive wheel 2131 and the ceramic ring. The drive wheel 2131 is rotatably connected to the positioning block 213. The outer surface of the drive rod 215 abuts against the drive wheel 2131. The motor 216 is fixed on the limiting plate 211, and the output end of the motor 216 is fixedly connected to the drive rod 215. The surface of the drive wheel 2131 is made of a high-friction material, such as rubber or sponge material, which is not specifically limited here. The purpose is to increase the friction between the ceramic ring and the drive wheel 2131. For example, the motor 216 drives the drive wheel 2131 to rotate, and the drive wheel 2131 uses friction to drive the ceramic ring to rotate.

[0038] In some embodiments, rollers are uniformly embedded in the surface of the ceramic ring positioning component 21 to reduce the friction between the ceramic ring and the ceramic ring positioning component 21.

[0039] See Figure 2 , Figure 4 and Figure 6As shown, there are two electrode positioning assemblies 22, which are opposite each other. Each electrode positioning assembly 22 includes a fixing block 221, a connecting frame 222, and a positioning rod 223. The fixing block 221 is fixed on the limiting plate 211. The end of the connecting frame 222 is hinged to the fixing block 221, and a torsion spring (not shown) is fixed at the hinge point between the connecting frame 222 and the fixing block 221. The torsion spring is used to provide radial elastic force to the connecting frame 222. The end of the positioning rod 223 is rotatably connected to the connecting frame 222. For example, the outer periphery of the electrode sheet is currently provided with a groove. In this embodiment, the positioning rod 223 is used to lock the outer periphery groove of the electrode sheet to achieve positioning. The elastic force is applied to the connecting frame 222 by the torsion spring, and the connecting frame 222 drives the positioning rod 223 to lock the groove. Since the positioning rod 223 is arc-shaped and the connecting frame 222 can rotate on the limiting plate 211, it will not affect the removal of the electrode sheet from between the two electrode positioning assemblies 22.

[0040] See 5. Figure 6 and Figure 7 As shown, the auxiliary component 23 includes a connecting seat 231, a handrail 232, an auxiliary frame 233, and a conduit 234. The connecting seat 231 is fixedly connected to the outer surface of the limiting plate 211, the handrail 232 is fixedly connected to the connecting seat 231, the auxiliary frame 233 is fixed to the end of the handrail 232, the end of the conduit 234 passes through the auxiliary frame 233 and is fixed, and the interior of the conduit 234 communicates with the inner cavity of the auxiliary frame 233. The outer surface of the auxiliary frame 233 is evenly provided with ceramic ring positioning grooves 2331 and electrode plate positioning grooves 2332. The ceramic ring positioning grooves 2331 and electrode plate positioning grooves 2332 are used to assist in positioning the ceramic ring and the electrode plate, respectively. The outer surface of the ceramic ring positioning grooves 2331 is provided with an adhesive outlet. The other end of the conduit 234 away from the auxiliary frame 233 is connected to a device that provides adhesive through a solenoid valve. By controlling the opening and closing of the solenoid valve, the supply of adhesive to the auxiliary frame 233 can be controlled.

[0041] For example, the ceramic ring is placed on the positioning block 213 and inserted into the ceramic ring positioning groove 2331 to assist in positioning the ceramic ring. The electrode plate is stuck between the two positioning rods 223 and located in the electrode plate positioning groove 2332 to assist in positioning the electrode plate. When the solenoid valve is opened, the glue is discharged from the glue outlet. The motor 216 drives the drive rod 215 to rotate. The drive rod 215 drives the ceramic ring to rotate through the drive wheel 2131, so that the glue can be evenly applied to the surface of the ceramic ring.

[0042] Furthermore, the inside of the glue outlet is embedded with a glue nozzle 2333, which is made of rubber. The purpose of the glue nozzle 2333 is that it is elastic. Only when the solenoid valve is opened and the glue supplying device provides glue pressure, if the pressure is greater than the elasticity of the glue nozzle 2333 itself, will glue be dispensed, thereby avoiding glue leakage.

[0043] See Figure 1 , Figure 2 and Figure 3 As shown, the clamping part 1 includes a first fixed seat 11, a second fixed seat 12, a fixed rod 13, a movable pressure plate 14, a driving member 15, and a fixed pressure plate 16. The two ends of the fixed rod 13 are fixedly connected to the first fixed seat 11 and the second fixed seat 12, respectively. The movable pressure plate 14 is slidably connected to the second fixed seat 12. The driving member 15 is fixed on the second fixed seat 12, and the output end of the driving member 15 is fixedly connected to the outer surface of the movable pressure plate 14. The driving member 15 is a cylinder, a hydraulic cylinder, or an electric actuator, depending on the actual situation. The fixed pressure plate 16 is slidably connected to the first fixed seat 11.

[0044] For example, after the ceramic ring and electrode ring are installed in place and the adhesive is applied, the auxiliary frame 233 is moved away from the ceramic ring by pushing the handle 232, as follows: Figure 7 As shown, by activating the drive unit 15, the movable pressure plate 14 is moved towards the fixed pressure plate 16, thereby bonding the ceramic ring and the electrode sheet.

[0045] For further details, please refer to [link / reference]. Figure 2 As shown, a circular groove 161 is formed through the outer surface of the fixed pressure plate 16, and a locking bolt 162 is provided through the circular groove 161. The fixed pressure plate 16 is fixedly connected to the first fixed seat 11 by the locking bolt 162. The purpose is to adjust the position of the fixed pressure plate 16 on the first fixed seat 11 to adapt to different specifications of the positioning part 2. For example, in this embodiment, if the number of positioning blocks 213 is increased, the combined thickness of all positioning blocks 213 increases, and the distance between the movable pressure plate 14 and the fixed pressure plate 16 needs to be increased.

[0046] Specifically, the outer surface of the movable pressure plate 14 is uniformly fixed with a first rubber pad 141 and a second rubber pad 142. The second rubber pad 142 abuts against the outer surface of the positioning block 213, and the first rubber pad 141 abuts against the ceramic ring. The purpose is that the movable pressure plate 14 can simultaneously push the ceramic ring and the positioning block 213 toward the fixed pressure plate 16 through the first rubber pad 141 and the second rubber pad 142. Example 2

[0047] See Figure 8 As shown, an electron accelerator tube bonding fixture, based on Embodiment 1, has a pressure frame hinged to a limiting plate 211, and a pressure roller rotatably connected to the pressure frame, as shown. Figure 8 As indicated by A and A1 respectively, the purpose is to prevent the ceramic ring from slipping and failing to rotate normally. By rotating the pressure frame, the pressure roller presses against the surface of the ceramic ring. This, together with the drive wheel 2131, clamps the magnetic ring, which can increase the friction between the ceramic ring and the drive wheel 2131 and ensure that the ceramic ring can rotate normally. Example 3

[0048] See Figure 9 As shown, an electron accelerator tube bonding fixture, based on Embodiment 1, has a driven gear coaxially connected and fixed to the drive wheel 2131, as shown in the attached figure. Figure 9 At the marked location 2131a, a drive gear is uniformly fixed to the outer surface of the drive rod 215, as shown in the attached diagram. Figure 9 At the marked 215a, the driven gear meshes with the driving gear, improving the transmission efficiency between the drive rod 215 and the drive wheel 2131. Example 4

[0049] See Figure 10 As shown, an electron accelerator tube bonding fixture, based on embodiment 1, allows for the replacement of the positioning rod 223 with an arc-shaped block that does not match the outer shape of the electrode sheet if the produced electrode sheet does not have a groove on its outer periphery. The circular electrode sheet can also be positioned by using the opposing arc-shaped blocks.

However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, which is determined by the appended claims.
