Description

Technical Field

[0001] The invention relates to a mechanical device for adjusting the angle of a device, and in particular to a non-magnetic insulation angle fine-tuning mechanism suitable for a high-temperature chamber. Background Art

[0002] In some scientific experiments, it is necessary to adjust the angle of the electromagnetic coil located inside the closed non-magnetic heating chamber. For example, in the in-situ optically pumped helium-3 neutron polarization device, it is necessary to ensure that the free induction decay (FID) coil is perpendicular to the adiabatic fast path (AFP) coil and the system axis. The degree of verticality determines the resolution of some measurement functions of the system. The verticality required in use is much higher than the tolerance that can be achieved during the preparation and assembly process, and it is necessary to achieve this verticality through an adjustment mechanism. In addition to realizing the function of fine angle adjustment, the adjustment mechanism also needs to have the following characteristics: 1. To avoid helium-3 depolarization, ferromagnetic materials such as iron and nickel are not used; 2. To avoid interfering with the RF magnetic field configuration, conductive materials should be used as little as possible; 3. The adjustment mechanism is installed in a high-temperature chamber, can continuously withstand an operating temperature of 260°C, and can be adjusted from outside the chamber; 4. No electromagnetic interference should be actively generated.

[0003] Commercially available adjustment mechanisms of this type, such as the Thor labs KM series and the Edmund Optics 34-723 mirror mount, can achieve angle adjustment, but they contain ferromagnetic springs, a large amount of aluminum alloy, and cannot be adjusted from the outside, which does not meet the requirements. Commercially available electric adjustment mounts, such as the Thorlabs KS1-Z9, can be adjusted from the outside of the device, but the circuits and motors contained therein not only generate electromagnetic field interference, but also cannot work at high temperatures, which also does not meet the requirements.

[0004] In order to meet the needs of in-situ optically pumped helium-3 neutron polarization devices and other similar devices, a coil angle adjustment mechanism is required, which is made of insulators as much as possible and can also achieve angle adjustment function. Moreover, the adjustment input of the mechanism should be able to be easily led out of the closed high-temperature chamber, so as to achieve the requirement of external adjustment under high-temperature conditions. Summary of the invention

[0005] The purpose of the present invention is to address the deficiencies in the prior art and provide a non-magnetic insulation angle fine-tuning mechanism suitable for a high-temperature chamber, thereby achieving the purpose of being able to adjust the pointing angle of an electromagnetic coil or other optical or electrical components located in the chamber from outside the high-temperature chamber.

[0006] To achieve the above object, the technical solution of the present invention is as follows:

[0007] A non-magnetic insulated angle fine-tuning mechanism suitable for a high-temperature chamber comprises a base installed inside the chamber and capable of adjusting the installation angle, a fine-tuning element capable of elastic deformation is fixedly arranged on the base, the fine-tuning element is connected to a component to be adjusted, a traction rope is connected to the component to be adjusted, the traction rope is extended to the outside of the chamber and connected to a fine-tuning actuating mechanism outside the chamber, the tensile stress on the traction rope is adjusted by the fine-tuning actuating mechanism, so that the fine-tuning element is elastically deformed, thereby achieving adjustment of the angle and / or position of the component to be adjusted.

[0008] Furthermore, in a specific embodiment, the traction rope is one or more ropes, which are respectively connected to different parts of the components to be adjusted; the traction rope is made of high temperature resistant insulating fiber material.

[0009] Furthermore, as described above, the non-magnetic insulated angle fine-tuning mechanism suitable for a high-temperature chamber is provided with one or more traction rope guide rings around the fine-tuning element, and the traction rope passes through the holes of the traction rope guide rings, is led to different parts of the component to be adjusted, and is connected to the traction rope fixing buckle on the component to be adjusted.

[0010] Furthermore, a clamping component is provided on the base, and the fine-tuning element and the traction rope guide ring are both fixed on the clamping component.

[0011] Furthermore, in a specific embodiment, a tensioner is provided on the traction rope, and the tensioner is composed of a screw and a nut, the traction rope is fixed on the screw and the nut respectively, and the length of the traction rope is adjusted by rotating the screw, so that the traction rope is tensioned in the working state.

[0012] Furthermore, in a specific embodiment, the fine-tuning element is a thin straight rod or a spiral rod made of non-ferromagnetic material.

[0013] Furthermore, the fine-tuning element is a glass thin straight rod or an aluminum alloy thin spiral rod.

[0014] Furthermore, in a specific implementation, the component to be adjusted is an electromagnetic coil or other optical or electrical component.

[0015] Furthermore, in a specific embodiment, a slot-shaped mounting hole is provided on the base, so that the base can be eccentrically mounted as required.

[0016] Furthermore, the shape of the base is adapted to the structure of the mounting surface inside the high temperature chamber.

[0017] Further, in a specific embodiment, the fine-tuning actuating mechanism is a manual fine-tuning actuating mechanism or an electric fine-tuning actuating mechanism; the manual fine-tuning actuating mechanism is composed of a threaded connecting member, and the traction rope is pulled by manually rotating the threaded connecting member; the electric fine-tuning actuating mechanism can use a stepper motor or a servo to pull the traction rope.

[0018] Furthermore, in a specific embodiment, the base, the clamping component, and the traction rope guide ring are all made of high temperature resistant plastic.

[0030] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0031] The present invention provides a non-magnetic insulating angle fine-tuning mechanism suitable for a high-temperature chamber, which extends a traction rope connected to a component to be adjusted to the outside of the high-temperature chamber, and adjusts the tensile stress on the traction rope outside. Since the component to be adjusted is fixed on an elastically deformable fine-tuning element, the pulling of the traction rope will cause the component to be adjusted to tilt or translate accordingly, thereby achieving the purpose of adjusting the pointing vector of the component.

[0032] The basic structure of the present invention includes a base installed inside the chamber and capable of adjusting the installation angle. The shape of the base is adapted to the structure of the installation surface inside the high-temperature chamber. A fine-tuning element capable of elastic deformation is fixedly arranged on the base. The fine-tuning element can be designed as a very thin rod-shaped structure and is made of non-ferromagnetic material. The fine-tuning element is connected to the component to be adjusted. A traction cable is connected to the component to be adjusted. The traction cable is guided by a traction cable guide ring. Different traction cables are connected to different parts of the component to be adjusted. Theoretically, when there is only one traction cable, the function of adjusting the angle of the component can be achieved to a certain extent. However, under this configuration, the adjustable degree of freedom dimension is only one dimension, and the adjustment target point may not fall within the adjustment range, resulting in poor adjustment flexibility and achievable accuracy. A more preferred solution is to use two or three traction cables. Two traction cables can achieve two-axis directional angle adjustment, and three traction cables can achieve single-axis translation adjustment on the basis of two-axis directional angle adjustment. Of course, a higher-dimensional adjustment method can also be achieved by setting more traction cables. The traction rope can be made of high-temperature resistant fiber material. The traction rope is led out to the outside of the chamber through a traction rope guide hole on the chamber wall and connected to a fine-tuning actuator outside the chamber. The tensile stress on the traction rope is adjusted by the fine-tuning actuator mechanism to cause the fine-tuning element to produce elastic deformation, thereby achieving adjustment of the angle and / or position of the component to be adjusted.

[0033] The components to be adjusted in the present invention may be electromagnetic coils or other optical or electrical components. The following takes the electromagnetic coil of an in-situ optically pumped helium-3 neutron polarization device as an example to specifically describe the non-magnetic insulation angle fine-tuning mechanism and its fine-tuning method of the present invention.

[0034] like Figure 1 As shown, the electromagnetic coil angle fine-tuning mechanism of this embodiment includes a base 100, a fine-tuning element 200, a coil winding bracket 300, and a traction rope 401. The base 100, the fine-tuning element 200 and the coil winding bracket 300 are combined into a whole by means of threads or bonding, and the end of the fine-tuning element 200 is vertically connected to the axis position of the coil winding bracket 300. The electromagnetic coil is wound in the winding groove 301 of the coil winding bracket 300, and the edge of the coil winding bracket 300 is provided with a traction rope fixing buckle 302. Among them, the design of the high-temperature cavity matching surface 101 of the base 100 should be selected according to the shape and size of the internal mounting surface of the high-temperature cavity. In this embodiment, it is an arc shape that matches the cylindrical cavity. In this embodiment, a slot-type mounting hole 104 is opened on the base 100, which is convenient for intentional eccentric installation during installation, so that the elastic adjustment range includes the adjustment target point. A clamping component 102 is fixed on the base 100 to clamp the fine-tuning element 200.

[0035] The fine-tuning element 200 is a thin rod-shaped structure, which can undergo reversible elastic deformation within the adjustment range, and the cross-section is much smaller than other components, which causes structural deformation to occur mainly on this element. In order to avoid helium-3 depolarization, non-ferromagnetic materials should be used, and ferromagnetic materials such as spring steel cannot be used. In this embodiment, the fine-tuning element 200 can be prepared with materials such as glass or hard aluminum alloy, and can be made into a thin glass straight rod or a spiral aluminum alloy rod (similar to the shape of a spring). The former is suitable for two-degree-of-freedom adjustment, and the latter is suitable for three-degree-of-freedom adjustment. The bottom end of the fine-tuning element 200 is fixedly connected to the clamping part 102 on the base 100, and the top end is fixedly connected to the axis of the coil winding support 300. The coil winding support 300 can be tilted around the fine-tuning element 200 under the action of external force, or when the fine-tuning element 200 is a spiral rod, it can also be translated in the vertical direction while tilting.

[0036] The coil winding support 300 is provided with a winding slot structure for winding the coil, and also with a traction rope fixing buckle 302 structure for fixing the traction rope 401. In this embodiment, the structure is realized by a small hole and a corresponding groove. The spatial position of the traction rope fixing buckle 302 should be set corresponding to the traction rope guide ring 103. In this embodiment, a plurality of traction rope guide rings 103 are provided around the fine-tuning element 200. The traction rope 401 passes through the holes of the traction rope guide ring 103, is led to different parts of the coil winding support 300, and is connected with the traction rope fixing buckle 302 on the coil winding support 300. The coil winding support 300 is pulled by the traction rope 401 through the traction rope guide ring 103, causing it to tilt around the fine-tuning element 200, thereby achieving the purpose of adjusting its angle. The traction rope guide ring 103 has a small hole through which the traction rope 401 can pass, and the bottom of the traction rope guide ring 103 is fixed to the clamping component 102 by screw thread or bonding. The characteristic of the traction cable guide ring 103 is that the force vector acting on the traction cable guide ring 103 starting from the traction cable fixing buckle 302 can generate a significant torque on the fine-tuning element 200. The position selection of the traction cable guide ring 103 should meet the following characteristics: when the corresponding traction cable is tensioned, the torque vector generated on the fine-tuning element 200 should be reasonably distributed in space so that the adjustment target point falls within the adjustment range.

[0037] The traction rope 401 should be made of fiber materials that can withstand the working temperature of the equipment (such as 260°C), such as aromatic polyamide fiber (Kevlar). The traction rope 401 should have a large elastic modulus, and its length does not change significantly when it is tensioned. In this embodiment, a tensioner 402 is provided on the traction rope 401. The tensioner 402 is composed of a screw and a nut. The traction rope 401 is fixed on the screw and the nut respectively. The length of the traction rope can be adjusted by rotating the screw, so that the traction rope is tensioned in the working state. At the same time, the traction rope 401 can be simply disconnected by removing the screws on the tensioner 402, which is convenient for equipment disassembly and maintenance.

[0038] like Figure 2 As shown, the traction rope 401 is led out to the outside of the chamber through a traction rope guide hole 502 processed on the chamber wall or the end cover, and is connected to the fine-tuning actuator 501 outside the chamber. The fine-tuning actuator 501 can be a manual fine-tuning actuator or an electric fine-tuning actuator. The manual fine-tuning actuator used in this embodiment is composed of a threaded connector. The traction rope is tightened by manually rotating the threaded connector. The traction rope pulls the coil winding bracket through the traction rope guide ring, causing the fine-tuning element to deform, thereby causing the coil winding bracket to tilt in the direction of the corresponding traction rope guide ring, and finally causing the axis of the coil winding bracket to coincide with the adjustment target point. For the sake of simplicity, Figure 2 Only one manual fine-tuning actuator is shown in the figure. In actual design, the number of manual fine-tuning actuators should be equal to the number of traction cables.

[0039] In addition, electric fine-tuning actuators such as stepper motors and servos can also be used instead. Figure 2 The manual fine-tuning actuation mechanism shown in the figure realizes the automatic operation of the system. In order to avoid interfering with the electromagnetic field in the cavity, any electric adjustment mechanism should be installed away from the cavity and electromagnetic shielding measures should be taken.

[0040] In addition to the fine-tuning element 200 and the traction rope 401, other components of the present invention can be made of high-temperature resistant plastics, such as polyetheretherketone (PEEK), so as to avoid interfering with the radio frequency magnetic field configuration and can also adapt to the working environment in the high-temperature chamber.

[0041] The fine-tuning method of the electromagnetic coil angle fine-tuning mechanism provided in this embodiment includes:

[0042] First, the fine-tuning mechanism is installed in a high-temperature chamber, the traction rope passes through the traction rope guide ring and is connected to the traction rope fixing buckle on the coil winding bracket, the installation angle of the base is adjusted so that the elastic adjustment range includes the adjustment target point, and the traction rope is extended to the outside of the chamber and connected to the fine-tuning actuator mechanism.

[0043] Then, the fine-tuning actuator mechanism is adjusted to tighten the traction rope. The traction rope pulls the coil winding bracket through the traction rope guide ring, causing the fine-tuning element to deform, thereby tilting the coil winding bracket in the direction of the corresponding traction rope guide ring, and finally making the axis of the coil winding bracket coincide with the adjustment target point.

[0044] Furthermore, in the above-mentioned fine-tuning method, when the fine-tuning element is a vertically compressible spiral structure, such as a spiral aluminum alloy rod, by adjusting the tensile stress of the three traction ropes, the coil winding bracket is tilted and translated in the vertical direction at the same time, and finally the axis center of the coil winding bracket coincides with the adjustment target point.

[0045] In an example using two traction ropes 401, Figure 2 When the external fine-tuning actuating mechanism 501 is tensioned, the traction rope 401 pulls the coil winding support 300 through the traction rope guide ring 103, causing the fine-tuning element 200 to deform (the fine-tuning element 200 can be a thin glass straight rod), so that the coil winding support 300 tilts in the direction of the corresponding guide ring, thereby achieving the purpose of adjusting the pointing vector of the coil winding support 300. The effect caused by this action is as follows Figure 3 As shown in (a), X B is the offset vector introduced by intentionally eccentric installation during installation, and X1 and X2 are the offset vectors introduced by tensioning the traction rope. By tensioning the traction rope 401, the magnitudes of the offset vectors X1 and X2 change. At this time, the orientation vector X of the coil winding support 300 is X B+X1+X2. It can be seen that the orientation of X can be adjusted arbitrarily within the deformation range allowed by the fine-tuning element 200, and the adjustment range is the maximum value of vectors X1 and X2 and the maximum value of vector X2. B The intersection of the triangle formed by the fine-tuning element 200 and the dotted circle determined by the elastic limit of the fine-tuning element 200 is shown in FIG. Figure 3 (a) is the shaded area. Based on this, when installing the fine-tuning mechanism, the offset vector X should be adjusted. B (ie, adjusting the installation angle of the base 100 by the slot-shaped installation hole 104), so that the elastic adjustment range includes the adjustment target point P0.

[0046] In another example using three traction ropes 401, Figure 3 As shown in (b), if the system includes three traction ropes instead of two, and the fine-tuning element 200 is changed from a straight line to a spiral shape (in this case, the fine-tuning element 200 can be a spiral aluminum alloy rod), the two-dimensional vector diagram becomes a three-dimensional vector diagram, in which the horizontal dimension represents the angle adjustment of the coil winding support 300, and the vertical dimension represents the translation of the coil winding support 300 in the vertical direction. At this time, the adjustment range is the maximum value that the vectors X1, X2, and X3 can take and the vector X B The intersection between the tetrahedron formed and the ellipsoid determined by the elastic limit of the fine-tuning element 200 is as follows: Figure 3 (b) is the shaded area. B The size of the elastic adjustment range includes the adjustment target point P0.

[0047] The electromagnetic coil angle fine-tuning mechanism provided in this embodiment can achieve two-axis pointing angle adjustment within a range of about 1° of the electromagnetic coil pointing vector, or achieve single-axis translation adjustment on the basis of achieving two-axis pointing angle adjustment. The device does not contain any ferromagnetic materials, and uses as little or no conductive materials as possible, avoiding helium-3 depolarization and interference with the RF magnetic field configuration. The mechanism can work for a long time at a temperature of 260°C, and the traction rope is adjusted outside the chamber. In the working state, there is an elastic preload to eliminate the clearance.
