Description

Technical fields: This invention relates to neutron conduit manufacturing and control technology in the field of nuclear technology, specifically a high-precision full-size conical neutron conduit control system and its integration method. Background Technology

[0001] As a key instrument for studying the microstructure and dynamics of matter, the splicing quality of the neutron conduit, a core component of the neutron spectrometer, directly affects the transmission efficiency and neutron flux of the neutron beam. Current neutron conduit splicing techniques suffer from the following limitations: Insufficient integration: Among the existing technologies searched, patent CN108511101B only adjusts the catheter support component and requires external structural assistance for splicing, and cannot complete the entire process independently; although the splicing platform CN116638485A achieves centralized assembly, it uses fixed-size tooling fixtures and is only suitable for straight catheter splicing, and cannot meet the needs of tapered catheters or variable-size catheters.

[0002] Limited applicability: Existing technologies lack splicing solutions for tapered neutron conduits, and the equipment specifications are limited. Changing the conduit size requires redesigning the tooling, resulting in high costs and long cycles.

[0003] Insufficient precision control: Traditional splicing methods rely on mechanical positioning and lack real-time precision feedback and fine-tuning mechanisms. Accumulated errors are difficult to control and cannot meet the stringent requirements of high-precision neutron spectrometers for the form and position tolerances of the conduit splicing (≤20μm).

[0004] Material and process defects: Metal-based splicing platforms are susceptible to deformation due to temperature, and traditional assembly processes cannot guarantee the precision coordination of multiple links, further aggravating splicing errors. Summary of the Invention

The titanium alloy positioning and adsorption unit undergoes multiple heat treatments to relieve stress, balancing strength and lightweight, and reducing cantilever load. The internal air path design and surface finishing (Ra≤0.8μm) of the positioning and adsorption unit ensure adsorption stability and splicing surface fit. The system components adopt a standardized interface design, which can be quickly disassembled and maintained. The drive handwheel and lead screw guide rail linear motion components enable manual fine control, making operation intuitive and lowering the technical threshold. Attached Figure Description

Detailed Implementation

[0022] This invention provides a high-precision full-size conical neutron catheter control system and its integration method, aiming to achieve high-precision splicing and control of conical neutron catheters through precise structural design and control mechanisms. The technical solution of this invention will be described in detail below with reference to specific embodiments and accompanying drawings.

[0023] like Figure 1-10 As shown, where Figure 1 and Figure 2The images show the overall structure diagram and side view diagram of the high-precision full-size conical neutron conduit control system, illustrating the overall layout of the system and the relative positions of each component. Figure 3 This is a schematic diagram of the bottom positioning component, which shows in detail the structure and connection method of the bottom marble pad block (30) and the substrate positioning adsorption unit component (31).

Figure 8 , Figure 9 and Figure 10 The figures show the overall structure, exploded structure, and cross-sectional structure of the neutron conduit assembly sample, illustrating its complete form and internal structure. The specific structure is described below: like Figures 1 to 10 As shown, the high-precision full-size conical neutron conduit control system of the present invention mainly includes a bottom storage cabinet (1), a marble base (2), a bottom positioning component (3), two sets of horizontal feed control components (4), a top feed control component (5), and a set number of positioning blocks (6). The components are precision-machined and assembled to form a stable control system. The bottom storage cabinet (1) is equipped with a pneumatic system (10) to provide necessary pneumatic support for the system.

[0024] The marble base (2) serves as the system's installation reference surface, and its top must be precision machined to ensure that the flatness meets design requirements. Marble material has good thermal stability and rigidity, which helps to reduce the impact of temperature changes on system accuracy.

[0025] The bottom positioning component (3) includes a bottom marble support block (30) and a substrate positioning and adsorption unit component (31). The positioning and adsorption component (31) is composed of a set number of positioning and adsorption units (310). Each positioning and adsorption unit (310) is machined with a set taper and is made of titanium alloy, which ensures strength while reducing weight and cantilever load. The positioning and adsorption unit (310) has an internal air passage, which generates negative pressure through a pneumatic system to achieve adsorption and fixation of the glass substrate. Multiple heat treatments are required during processing to relieve stress and ensure material stability.

[0026] The horizontal feed control component (4) includes a marble mounting base plate (40), on which a lead screw guide rail linear motion component (41) and a measurement system component (42) are mounted. The lead screw guide rail linear motion component (41) drives the marble motion platform (43) to move along the linear guide rail (410) to achieve precise horizontal positioning. A substrate positioning adsorption component (44) is provided at the end of the marble motion platform (43), which has a similar structure to the bottom positioning component (31) and is used to adsorb and fix the glass substrate. The measurement system component (42) includes an encoder system component (420), a contact sensor component (421), and a micrometer component (422) for fine-tuning of accuracy.

[0027] The top feed control assembly (5) has a similar structure to the horizontal feed control assembly (4), including a marble mounting plate (50), a lead screw guide rail linear motion assembly (51), and a measurement system assembly (52). The lead screw guide rail linear motion assembly (51) drives the marble motion platform (53) to move along the linear guide rail (510) to achieve precise vertical positioning. The end of the marble motion platform (53) is also equipped with a substrate positioning adsorption assembly (54) for adsorbing and fixing the glass substrate. The measurement system assembly (52) works in conjunction with the top pull bracket (55) to achieve fine-tuning of precision.

[0028] The positioning block (6) is used for auxiliary positioning and locking. After preliminary machining, it is locked onto the marble tabletop with a margin on the positioning edge. Finally, it is machined to the positioning dimensions according to the drawing requirements. A groove or chamfer is set at the bottom to avoid affecting the assembly accuracy. The tapered standard sample block (7) has all surfaces that are precision machined. It is only used as a calibration scale during installation and debugging. 440C with a small coefficient of linear expansion is selected as the machining material to reduce the impact of ambient temperature changes on accuracy.

[0029] Example 1: Installation and Debugging Process Preparations before installation and debugging in this embodiment: S1. In this embodiment, the tapered standard sample block (7) is precision machined with a set machining accuracy; S2. In this embodiment, the initial machining of the marble base (2) and the positioning block (6) is completed with the set machining accuracy. The top of the marble base (2) needs to be machined a second time according to the set flatness requirements. After the above work is completed, the positioning block (6) is locked on the marble base (2). The two are machined as a whole according to the set assembly accuracy, and the allowance of the positioning block (6) on the positioning edge is reduced to the set positioning size. S3. In this embodiment, the initial machining of the bottom marble shim block (30) and the positioning adsorption unit (310) is completed with the set machining accuracy. The bottom shim block (30) is locked on the marble base (2), and the assembled positioning adsorption assembly (31) is locked on the bottom shim block (30). After completing the above work, the bottom positioning assembly (3) together with the marble base (2) and the positioning block (6) are put on the machine tool for final precision machining. S4. In this embodiment, the initial machining of the marble mounting base plate (40), marble movement platform (43) and positioning adsorption unit (440) is completed with the set machining accuracy. The bottom surfaces of the marble mounting base plate (40) and marble movement platform (43) are used as reference surfaces for machining and installation and need to ensure a certain form and position accuracy. The top surface of the marble mounting base plate (40) and the bottom surface of the marble movement platform (43) are evenly distributed with steps at the set position. The inner side is taken as the positioning reference surface for the installation of the linear guide rail (410) and the slider (411). After the above machining is completed, the positioning adsorption assembly (44) is assembled and it is finally finished with the marble movement platform (43) as a whole. S5. In this embodiment, the initial machining of the marble mounting plate (50), marble moving platform (53) and positioning adsorption unit (540) is completed with the set machining accuracy. The bottom surface of the marble mounting plate (50) and marble moving platform (53) is used as the reference surface for machining and installation and needs to ensure a certain shape and position accuracy. The top surface of the marble mounting plate (50) and the bottom surface of the marble moving platform (53) are evenly distributed with steps at the set position. The inner side is taken as the positioning reference surface for the installation of linear guide rail (510) and slider (511). After the above machining is completed, the positioning adsorption component (54) is assembled and it is finally finished with the marble moving platform (53) as a whole. S6. In this embodiment, the horizontal feed control component (4) and the top feed control component (5) are assembled to ensure the normal operation of the lead screw guide linear motion component (41) (51). The measurement system component (42) (52) will be installed during the formal installation and debugging process. The specific assembly process of the lead screw guide linear motion component (41) (51) is not described here.

[0030] The installation and debugging process in this embodiment is as follows: Step 1: Since the secondary precision machining of the bottom positioning component (3) is completed on the marble base (2), the marble base (2), positioning block (6) and bottom positioning component (3) that have been precision machined with the set assembly precision should be cleaned together before installation and then installed. Step 2: Install and fix the conical standard sample block (7) on the bottom positioning component (3), with its four sides aligned with the four sides of the positioning adsorption component (31); Step 3: Install the two sets of horizontal feed control components (4) to the set position. After the positioning point is close, lock the mounting bolt. At this time, drive the screw (414) by rotating the end drive handwheel (416), thereby driving the screw guide rail linear motion component (41) to drive the positioning adsorption component (44) to slowly approach the conical standard sample block (7). Observe the fit. There may be a small error at this time, which will be dealt with later. Step 4: Install the top feed control component (5) onto the marble base and press it against the positioning block (6). At this time, it is necessary to check the perpendicularity of the mounting surface of the linear guide rail (510) of the top marble motion platform (53) and the top surface of the marble base (2) on the coordinate measuring machine. If the perpendicularity does not meet the standard, it is necessary to use micron-level shims to fine-tune it until it is qualified, and finally lock it. Step 5: Loosen the locking screw in the locking nut (517) of the lead screw (514), slowly rotate the end drive handwheel (516) to drive the lead screw (514) to rotate, thereby driving the linear motion assembly (51) of the lead screw guide rail to drive the positioning adsorption assembly (54) to slowly approach the conical standard sample block (7), observe the fit. Since it is processed as a whole, the error will not be too large. Fine adjustment will be made by adjusting the micrometer assembly (522) later. Step 6: Install all micrometer components (422) and (522) into place for subsequent fine-tuning. Step 7: Fine-tune the horizontal feed control component (4): Slightly loosen the mounting screws of the marble motion platform (43) in the horizontal feed control component (4), adjust the micrometer component (422) to make the positioning adsorption unit (440) and the conical standard sample block (7) fit tightly together, use a 5μm feeler gauge to check and confirm, lock the mounting bolts after they are tightly fitted, check again, and after confirming that there are no errors, adjust the next control component; Step 8: Complete the fine-tuning of the top feed control component (5) in the same manner; Step 9: After all the control components are finely adjusted to their positions, in order to monitor the position dimensions in real time, except for the bottom positioning component (3), which is a fixed positioning device and does not need to be monitored, the other three control components are equipped with micron-level precision contact sensor components (421) (521) at symmetrical positions on both sides of the rear end of the marble motion platform (43) (53) to reduce the sway error between the actual position and the set position of the motion platform. Step 10: To cope with the splicing of tapered neutron conduits of different specifications and sizes, an encoder system component (420) (520) is added to the side of each control component as a tool for calibration, and at the same time to understand the real-time position and size of the neutron conduit during splicing. The specific assembly process of the encoder system component (420) (520) will not be described here. Step 11: Loosen the micrometer assembly (422) (522), remove the top pull bracket (55), take away the conical standard sample block (7), and use a coordinate measuring machine to check the positioning surface size of the conical inner cavity formed by each positioning adsorption assembly.

[0031] The installation and commissioning of the cone-shaped neutron catheter control system are now complete. The next step is to assemble the catheter prototype.

[0032] Example 2: Catheter splicing process Step 1: Measure the thickness of the glass substrates to be spliced, determine the error between the thickness and the theoretical thickness, use an encoder system to compensate for the thickness, and calibrate the actual target position. Step 2: Use a dispensing machine to apply adhesive to the bonding area of ​​the substrate, being careful to control the amount of adhesive applied. Step 3: Place the bottom glass on the bottom positioning adsorption unit assembly (31) and align it with the surrounding area. At this time, turn on the pneumatic system (10) and use the vacuum generator to generate negative pressure to adsorb and fix the bottom glass substrate. Step 4: Apply adhesive to the joint surfaces of the two steps of the side glass substrate and place it on the positioning surface of the front positioning adsorption assembly (44). The bottom and top edges are temporarily positioned by auxiliary positioning blocks to make the four sides aligned. At this time, turn on the pneumatic system (10) and generate negative pressure by the vacuum generator to adsorb and fix the side glass substrate. Release the auxiliary positioning blocks and slowly rotate the end drive handwheel (416) to drive the lead screw (414) to rotate, thereby driving the lead screw guide rail linear motion assembly (41) to drive the positioning adsorption assembly (44) to slowly approach the target position until it moves to the target position. Finally, lock the locking nut (417). The method on the other side is the same as above. Step 5: Place the top glass on the top positioning adsorption unit assembly (54) and align it with the surrounding area. At this time, turn on the pneumatic system (10) and use the vacuum generator to generate negative pressure to adsorb and fix the top glass substrate. Slowly rotate the end drive handwheel (516) to drive the lead screw (514) to rotate, thereby driving the lead screw guide rail linear motion assembly (51) to drive the positioning adsorption assembly (54) to slowly approach the target position until it moves to the target position. Finally, lock the locking nut (517).

[0033] Since the glass substrate is also precision processed, each side of the substrate can also be used as a positioning reference. Therefore, in this step, the top glass substrate can be placed on the positioning steps set by the two side glass so that the substrate is flush with the positioning surface. Then, the linear motion component (51) of the screw guide rail is driven to move the positioning adsorption component (54) to the target position and lock the locking nut (517). Finally, the top glass substrate is adsorbed and positioned by negative pressure. Step 6: Wait for it to cure; Step 7: After curing, turn off the pneumatic system (10) to release the negative pressure, take out the spliced ​​sample of the neutron conduit, and measure the size. The relevant dimensions and geometric tolerances must be less than 20μm. Step 8: Observe the bonding strength of the adhesive. If necessary, add more adhesive from the outside to cure and strengthen it. After curing, test and put it into storage.

[0034] This completes the assembly of the cone-shaped neutron conduit sample.

[0035] Through the above specific embodiments, the high-precision full-size conical neutron conduit control system of the present invention can achieve high-precision neutron conduit splicing and control, meeting the needs of scientific research and industrial applications. More specifically, the conical neutron conduit samples spliced ​​by this system, verified by a coordinate measuring machine, show that the dimensional tolerances of the positioning surfaces are all controlled within ±15μm, verifying high precision and reliability. This provides a scalable and highly adaptable conduit splicing solution for neutron spectrometers, significantly improving scientific research efficiency and data accuracy.
