Description

Technical Field

[0001] This utility model relates to the field of accelerator assembly equipment technology, and in particular to a positioning device for ceramic electrodes in accelerator tubes. Background Technology

[0002] Early BNCT accelerators often used adhesive-bonded accelerator tubes. In some accelerator tube designs where other connection methods are inconvenient, adhesive bonding is also considered. Adhesive-bonded accelerator tubes use glass rings and stainless steel electrodes bonded together with adhesive. This method achieves good sealing at room temperature. Due to the pressure difference between the inside and outside of the accelerator tube, as well as assembly and usage considerations, the accelerator tube must also possess sufficient mechanical strength. When considering complex load conditions, high operating temperatures, and reliability factors, ceramic / metal welding is usually the only viable connection method.

[0003] Before welding in the accelerator tube process, all components must be assembled. Traditional assembly processes can only perform precise positioning on some components of the accelerator tube. However, the accelerator tube is composed of multiple layers of welded components, and the overall coaxiality and alignment of the accelerator tube are extremely important for subsequent use. Components that are not precisely positioned result in significant differences in coaxiality and alignment, failing to meet actual usage requirements, leading to low production efficiency and high production costs. Therefore, this invention proposes a positioning device for the ceramic electrode of an accelerator tube, which provides precise positioning of multiple layers of components, improving assembly and welding accuracy and production efficiency. Utility Model Content

[0004] The purpose of this invention is to address the problem in the background technology that when assembling ceramic and metal welded accelerator tubes, traditional processes can only position some parts, resulting in large coaxiality and centering deviations after multi-layer part assembly, which cannot meet the usage requirements, and also leads to low production efficiency and high production costs. The invention proposes a positioning device for ceramic electrodes in accelerator tubes.

[0005] The technical solution of this utility model is: a positioning device for ceramic electrodes of an accelerator tube, including a template angle ruler. A ceramic template for constraining the uppermost ceramic ring of the accelerator tube is fixedly installed at the top of the template angle ruler. Multiple sets of ceramic electrode templates are also arrayed along the height direction of the template angle ruler. A base is provided below the template angle ruler.

[0006] A longitudinal adjustment plate is fixedly installed at the rear of the base for longitudinally limiting the template angle ruler;

[0007] The base is also equipped with two sets of lateral adjustment plates on both sides to laterally limit the guide square.

[0008] Optionally, the ceramic electrode template is configured in several groups, and each group of ceramic electrode templates is detachably connected to the template square by two bolts and two pins, which is used to position the ceramic ring and electrode of the accelerator tube.

[0009] Optionally, the side of the template angle ruler away from the ceramic electrode template is fixedly connected with reinforcing ribs to prevent deformation of the template angle ruler during processing.

[0010] Optionally, the template square is detachably connected to the base by bolts.

[0011] Optionally, the positioning surface of the ceramic template is an arc-shaped structure adapted to the outer circle of the ceramic ring of the accelerator tube.

[0012] Optionally, the limiting surface of the ceramic electrode template is provided with a positioning groove that matches the shape of the accelerator tube ceramic ring and the electrode.

[0013] Optionally, the base is provided with a U-shaped mounting hole for adjusting the installation position of the template square, and a bolt passes through the U-shaped mounting hole and is threadedly connected to the template square.

[0014] In summary, this application includes at least one of the following beneficial technical effects:

[0015] This utility model uses a ceramic template at the top of a template square to precisely limit the position of the uppermost ceramic ring of the accelerator tube, directly constraining the installation reference of the core component, effectively reducing the coaxiality deviation between the ceramic ring and the lower multi-layer ceramic electrode accessories, and ensuring that the overall alignment of the accelerator tube meets the requirements for welding and subsequent use.

[0016] Furthermore, by using several ceramic electrode templates distributed along the template angle, the multi-layer ceramic components and electrodes of the accelerator tube can be positioned and limited simultaneously, avoiding the cumulative error caused by single-layer positioning, greatly improving the assembly consistency of multi-layer parts, and the reinforcing ribs behind the template angle significantly enhance the overall rigidity of the structure.

[0017] Furthermore, the U-shaped groove in the base provides adjustable movement space for the template square. Combined with the longitudinal adjustment plate to calibrate the longitudinal assembly accuracy of the template square and the base, and the transverse adjustment plate to optimize the transverse installation accuracy of the base, a multi-dimensional adjustment system is formed. This system can not only adapt to the assembly requirements of different specifications of accelerator tubes, but also further improve the overall positioning accuracy through precise fine-tuning.

[0018] In summary, the high-precision and high-efficiency positioning achieved by the coordinated operation of the various components of this utility model reduces the repeated adjustments and rework in traditional mounting processes, shortens the assembly cycle, and improves production efficiency. Precise positioning reduces the scrap rate of parts caused by coaxiality and centering deviations, indirectly reducing production costs, and thus possessing both technical and economic value.

[0023] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0024] The components of the present invention embodiments described and shown in the accompanying drawings can typically be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0025] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Example: Figure 1 and Figure 2 As shown, this utility model proposes a positioning device for ceramic electrodes in an accelerator tube, including a template angle ruler 3. A ceramic template 1, which constrains the uppermost ceramic ring of the accelerator tube, is fixedly installed at the top of the template angle ruler 3. The positioning surface of the ceramic template 1 is an arc-shaped structure adapted to the outer circle of the ceramic ring of the accelerator tube. Multiple sets of ceramic electrode templates 2 are also arrayed along the height direction of the template angle ruler 3. The limiting surface of the ceramic electrode template 2 is provided with a positioning groove adapted to the shape of the ceramic ring and electrode of the accelerator tube. A reinforcing rib 4 is fixedly connected to the side of the template angle ruler 3 away from the ceramic electrode template 2 to prevent deformation of the template angle ruler 3 during processing. The reinforcing rib 4 on the side of the template angle ruler 3 is made of the same metal material as the template angle ruler 3 and is fixed by welding. It can effectively distribute the load borne by the template angle ruler 3 and avoid bending or deformation under the heat of processing, assembly or welding, thus ensuring the long-term stability of the positioning reference.

[0027] The ceramic electrode template 2 is set into several groups. Each group of ceramic electrode template 2 is detachably connected to the template square 3 by two bolts 8 and two pins 9, which is used to position the ceramic ring and electrode of the acceleration tube.

[0028] Combination Figure 1 As shown, a base 6 is located below the template square 3. A longitudinal adjustment plate 5 is fixedly installed behind the base 6 to limit the longitudinal movement of the template square 3. Specifically, a transverse adjustment plate 7 is precisely fitted with the rear end face of the template square 3 to form a longitudinal positioning reference surface, preventing the template square 3 from shifting longitudinally. The template square 3 and the base 6 are detachably connected by bolts 8. The base 6 has U-shaped mounting holes for adjusting the installation position of the template square 3. The bolts 8 pass through the U-shaped mounting holes and are threadedly connected to the template square 3. Two sets of transverse adjustment plates 7 are also provided on both sides of the base 6 to limit the transverse movement of the template square 3. The transverse adjustment plates 7 limit the transverse displacement of the template square 3 by tightly fitting with the side of the template square 3, ensuring the transverse stability of the positioning reference.

[0029] In this embodiment, the core positioning reference is the template angle ruler 3, which, together with the ceramic template 1, multiple sets of ceramic electrode templates 2, and multi-dimensional adjustment components, enables the precise installation of the multi-layer ceramic ring and electrodes of the accelerator tube. The installation process is as follows:

[0030] First, fix the base 6 on the assembly platform. Then, calibrate the horizontal accuracy of the base 6 using the two side horizontal adjustment plates 7. Next, use the rear longitudinal adjustment plate 5 to longitudinally limit and calibrate the position of the template square 3. Then, install the template square 3 at the U-shaped mounting hole of the base 6 using bolts 8. Fine-tune the horizontal position of the template square 3 according to the accelerator tube assembly requirements, and tighten the bolts 8 to complete the reference fixation. Next, according to the accelerator tube specifications, fix multiple sets of ceramic electrode templates 2 in an array along the height direction of the template square 3 using bolts 8 and pins 9, ensuring that the positioning grooves of each set of templates are on the same axis. Bolts 8 are responsible for aligning the ceramic electrode templates 2 with the template square 3. The fastening connection is achieved by pin 9, which precisely positions the relative positions of the two parts to prevent circumferential rotation or displacement during assembly. This ensures that the positioning grooves of each set of templates are on the same axis. Then, the electrodes of each layer of the accelerator tube and the ceramic ring are placed into the positioning grooves of the ceramic electrode template 2 in sequence. The precise fit between the positioning grooves and the shape of the parts provides dual constraint on the parts from both radial and circumferential directions, preventing the parts from loosening during assembly or welding. Finally, the uppermost ceramic ring is fitted to the arc-shaped positioning surface of the ceramic template 1 to complete the positioning. Through the coordinated constraint of each template, the coaxiality and centering positioning of all parts are achieved, preparing for the subsequent welding process.

[0031] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
