Description

Technical Field

[0001] This invention relates to the field of electromagnetic acceleration technology, and in particular to a mover supply device for a magnetoresistive accelerator and a magnetoresistive accelerator. Background Technology

[0002] A magnetoresistive accelerator mainly consists of a drive coil, a ferromagnetic mover, a guide tube, and auxiliary components. Its working principle is that the change in magnetic flux between the drive coil and the ferromagnetic mover provides power to the mover, converting electrical energy into the mover's kinetic energy. The mover supply mechanism of a magnetoresistive accelerator typically needs to deliver the movers stored in the mover chamber to a designated position at the beginning of the guide tube.

[0003] Due to the influence of the magnetic flux conversion position, the mover of a magnetoresistive accelerator has an optimal initial position. However, since the mover compartment usually needs to be easy to disassemble and replace, it is often not connected to the guide tube as a whole. This makes it difficult to guarantee the coaxiality between the mover compartment outlet and the guide tube. During the replacement and installation of the mover compartment, if a slight misalignment occurs, it can easily cause the mover to get stuck when it moves from the mover compartment outlet to the guide tube. This will seriously affect the mover supply efficiency or even prevent the mover from being supplied normally. Summary of the Invention

[0004] In view of this, the present invention aims to provide a mover supply device for a magnetoresistive accelerator and a magnetoresistive accelerator, so as to solve the problem in the prior art that it is difficult to ensure the coaxiality between the mover compartment outlet and the guide tube during the installation and replacement of the mover compartment.

[0005] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0006] A mover supply device for a magnetoresistive accelerator includes a mover compartment, a transition seat, and a pushing device. At least a portion of the mover compartment is capable of being inserted into or removed from the transition seat. The interior of the mover compartment is used to store movers. The transition seat is connected to the guide tube of the magnetoresistive accelerator. The transition seat is provided with a mover compartment limiting part for limiting the mover compartment when it is inserted into the transition seat, and for ensuring that the central axis of the mover compartment's outlet is collinear with the central axis of the guide tube. The pushing device is used to push the mover from the outlet of the mover compartment to a set position within the guide tube.

[0007] Preferably, the transition seat is provided with a transition tube, one end of the guide tube passes through the transition tube and is directly opposite the outlet of the moving part compartment.

[0008] Preferably, the moving part is provided with an outlet section at the outlet, and a guide notch is formed on the upper side of the outlet section. One end of the guide tube is disposed in the transition tube and is provided with an inlet section. The inlet section passes through the transition tube and extends into the guide notch in a direction close to the moving part.

[0009] Preferably, the pushing device includes a driving unit and a lever. One end of the lever is connected to the output end of the driving unit, and the other end can move along an arc-shaped trajectory to push the mover from the outlet of the mover compartment to a set position in the guide tube.

[0010] Preferably, the moving part includes a moving part base, a moving part body, a spring, and a bracket. The bottom of the moving part body is connected to the moving part base, and a moving part cavity is formed between the moving part body and the moving part base. The spring and the bracket are both disposed in the moving part cavity. The lower end of the spring is connected to the moving part base, and the upper end is connected to the bracket.

[0011] Preferably, the upper part of the moving part housing is provided with a moving part limiting part and a discharge section, the moving part limiting part and the discharge section are arranged adjacent to each other, and the moving part limiting part is located on the side of the discharge section away from the outlet.

[0015] Furthermore, the magnetoresistive accelerator also includes a power supply and a drive coil assembly. The drive coil assembly includes a guide tube, and multiple isolation plates are provided on the outer wall of the guide tube. A wire is provided between any two isolation plates, and the wire is wrapped around the outer wall of the guide tube and connected to the power supply.

[0016] Compared with the prior art, the mover supply device and magnetoresistive accelerator of the present invention have the following advantages:

[0017] The present invention discloses a mover supply device for a magnetoresistive accelerator and a magnetoresistive accelerator. By setting a transition seat, the mover chamber is assembled with the guide tube through the transition seat. On the one hand, this does not cause spatial obstruction to the assembly and disassembly of the mover chamber, making it convenient for the assembly, disassembly, and replacement of the mover chamber. On the other hand, when the mover chamber is installed in the transition seat, the mover chamber can be limited by the mover chamber limiting part to ensure that the central axis of the mover chamber's outlet is collinear with the central axis of the guide tube. This ensures the coaxiality of the mover chamber's outlet and the guide tube and avoids the movement jamming of the mover caused by misalignment between the mover chamber and the guide tube during installation.

[0028] The inventive concepts of this application will be described below using terminology commonly used by those skilled in the art to communicate the essence of their work to others skilled in the art. However, these inventive concepts may be embodied in many different forms and should not be construed as limited to the embodiments described herein.

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0030] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] To address the issue of ensuring coaxiality between the mover compartment outlet and the guide tube during installation and replacement in existing technologies, this embodiment proposes a mover supply device for a magnetoresistive accelerator, as shown in the attached figure. Figure 1-7 As shown, the mover supply device includes a mover compartment 1, a transition seat 2, and a pushing device 4. At least a portion of the structure of the mover compartment 1 can be inserted into or removed from the transition seat 2. The interior of the mover compartment 1 is used to store the mover 3, which is accelerated. The transition seat 2 is connected to the guide tube 51 of the magnetoresistive accelerator. The transition seat 2 is provided with a mover compartment limiting part 22, which is used to limit the mover compartment 1 when it is inserted into the transition seat 2, and to make the central axis of the outlet 15 of the mover compartment 1 collinear with the central axis of the guide tube 51. The pushing device 4 is used to push the mover 3 from the outlet 15 of the mover compartment 1 to a set position in the guide tube 51.

[0032] This application provides a transition seat 2, which allows the moving chamber 1 to be assembled with the guide tube 51 via the transition seat 2. On the one hand, this does not obstruct the disassembly and assembly of the moving chamber 1, making it easy to disassemble, assemble, and replace the moving chamber 1. On the other hand, when the moving chamber 1 is installed in the transition seat 2, the moving chamber 1 can be limited by the moving chamber limiting part 22, ensuring that the central axis of the outlet 15 of the moving chamber 1 is collinear with the central axis of the guide tube 51. This ensures the coaxiality of the outlet 15 of the moving chamber 1 and the guide tube, and avoids the movement of the moving part 3 from being stuck due to misalignment between the moving chamber 1 and the guide tube 51 during installation.

[0033] The mover 3 is a conventional ferromagnetic mover, which can be directly adopted using existing technology, and will not be described in detail.

[0034] Specifically, the transition seat 2 is provided with a transition tube 24, and one end of the guide tube 51 passes through the transition tube 24 and is directly opposite the outlet 15 of the moving chamber 1. Thus, the transition seat 2 not only limits the moving chamber 1, but also limits the assembly and orientation of the guide tube 51, so that the transition seat 2 can assemble and limit the moving chamber 1 and the guide tube 51 together, avoiding any offset or misalignment of the moving chamber 1 or the guide tube 51, and further ensuring the coaxiality of the outlet 15 of the moving chamber 1 and the guide tube.

[0035] Preferably, the diameter of the circular hole corresponding to the outlet 15 is the same as the inner diameter (i.e., inner wall diameter) of the guide tube 51. Based on the coaxiality of the outlet 15 of the mover compartment 1 and the guide tube, the spatial attitude of the mover 3 will not change during the process of being pushed from the outlet 15 into the guide tube 51, and there will be no deflection or misalignment, further eliminating the problem of movement jamming of the mover 3.

[0036] The transition seat 2 has an assembly cavity 21, and at least a portion of the structure of the moving part 1 (such as the upper part) can be inserted into and removed from the assembly cavity 21 to facilitate the disassembly and replacement of the moving part 1. For ease of description, this application is based on the direction in which the moving part 1 is inserted into the transition seat 2 from bottom to top. Accordingly, the bottom of the transition seat 2 (assembly cavity 21) is open downwards for the disassembly and assembly of the moving part 1 in the assembly cavity 21.

[0037] The moving part 1 has an outlet section 19 at the outlet 15. A guide notch 17 is formed on the upper side of the outlet section 19. One end of the guide tube 51 is located inside the transition tube 24 and has an inlet section 511. The inlet section 511 penetrates the transition tube 24 and extends towards the moving part 1 into the guide notch 17. This allows the transition tube 24 to support and fix the guide tube 51. Furthermore, without obstructing the disassembly and assembly of the moving part 1, the outlet section 19, inlet section 511, and outlet 15 together form a guiding channel for the moving part 3. This ensures that the moving part 3, when pushed from the moving part 1 into the guide tube 51, smoothly enters the guide tube 51 under the guidance of the inlet section 511, preventing displacement or misalignment and further eliminating movement jamming. Preferably, the moving part 3 moves along the inlet section 511 to ensure its guiding effect. The inlet section 511 can fill the guide gap 17 formed on the upper side of the outlet section 19, so that the inlet section 511 and the outlet 15 can form a channel that matches the size of the mover 3, so as to ensure that the mover 3 itself will not be offset or misaligned.

[0038] It should be noted that due to the setting of the guide notch 17, the outlet 15 is not a complete circular hole. To avoid ambiguity, the diameter of the outlet 15 will only be referred to as the diameter of the circular hole corresponding to the outlet 15 in this application. At the same time, the inlet section 511 can be regarded as a section of arc-shaped sidewall extending from the end of the guide tube 51, and is not a complete circular tube.

[0039] The pushing device 4 includes a drive unit 41 and a lever 42. One end of the lever 42 is connected to the output end of the drive unit 41, and the other end is used to push the mover 3 from the outlet 15 of the mover compartment 1 to a set position in the guide tube 51. The drive unit 41 can be a small motor or servo motor. During mover supply, its output shaft drives the lever 42 to move, thereby pushing the mover 3. Preferably, the lever 42 is an L-shaped lever. The drive unit 41 is connected to one end of the lever 42 and drives the lever 42 to rotate, causing the other end of the lever 42 to move along an arc-shaped trajectory. For example, according to actual mover supply needs, the other end of the lever 42 can reciprocate along an arc-shaped trajectory. That is, after the drive unit 41 rotates a certain angle and the lever 42 pushes the current mover 3 into place, the drive unit 41 reverses and resets to facilitate pushing the next mover 3. At the same time, this arc-shaped trajectory will cause the push force of the lever 42 on the mover 3 to tilt upward, ensuring that the mover 3 remains in contact with the guide section 511 and moves along the guide section 511 to the optimal initial position, further ensuring the guiding effect of the guide section 511 on the mover 3.

[0040] The moving part compartment 1 includes a moving part compartment base 11, a moving part compartment body 12, a spring 13, and a bracket 14. The bottom of the moving part compartment body 12 is connected to the moving part compartment base 11. For example, the moving part compartment base 11 is inserted into the moving part compartment body 12 through a slot, which serves to fix the bottom of the entire moving part compartment 1. A moving part compartment cavity is formed between the moving part compartment body 12 and the moving part compartment base 11. The spring 13 and the bracket 14 are both disposed in the moving part compartment cavity. The lower end of the spring 13 is connected to the moving part compartment base 11, and the upper end is connected to the bracket 14. The side of the bracket 14 away from the spring 13 is used to support the moving part 3, and under the action of the spring 13, it can push the moving part 3 to move upward. Preferably, the side of the bracket 14 away from the spring 13 is provided with a semi-circular groove so as to fit with the outer contour of the moving part 3. At the same time, under the support of the bracket 14, multiple moving parts 3 can be sequentially inserted into the moving part compartment cavity from top to bottom. It should be noted that the outlet 15 is for the purpose of understanding the supply process of the mover 3. If the mover 3 is to be loaded into the mover compartment 1, it can be loaded at the outlet 15.

[0041] The upper part of the mover compartment body 12 is provided with a mover limiting part 16 for limiting the mover 3 in the mover compartment cavity. Preferably, the upper part of the mover compartment body 12 is provided with a mover limiting part 16 and a discharge section 19. The mover limiting part 16 and the discharge section 19 are arranged adjacent to each other, and the mover limiting part 16 is located on the side of the discharge section 19 away from the outlet 15. In this way, while realizing the limiting of the mover 3 in the mover compartment cavity and the cooperation between the discharge section 19 and the inlet section 511, the structural complexity of the mover compartment body 12 can be simplified, and it is also convenient to replace or fill the mover 3. Correspondingly, the discharge section 19 can also be regarded as a section of the mover limiting part 16, and part of the structure can be omitted to form the guide notch 17 to achieve cooperation with the inlet section 511.

[0042] Specifically, regarding the limiting of the moving chamber 1 by the transition seat 2, the size of the assembly cavity 21 of the transition seat 2 is slightly larger than the size of the moving chamber 1 to facilitate the insertion of the moving chamber 1. Based on this, a moving chamber limiting part 22 is provided on the upper part of the transition seat 2. The inner wall size and outline of the moving chamber limiting part 22 are the same as the outer wall size and outline of the moving chamber limiting part 16 on the top of the moving chamber body 12. When the moving chamber 1 is inserted into the transition seat 2, the inner wall of the moving chamber limiting part 22 and the outer wall of the moving chamber limiting part 16 are completely fitted together to form an abutment, thereby providing guidance and limiting for the installation of the moving chamber 1.

[0043] Preferably, the pushing device 4 is positioned above the transition seat 2 to avoid obstructing the space for disassembling and assembling the moving part 1. Simultaneously, a first clearance opening 18 is provided on the upper part of the moving part limiting part 16, which communicates with the guide notch 17; a second clearance opening 23 is provided on the upper part of the moving part limiting part 22, located above the first clearance opening 18 and the guide notch 17. This ensures that during the movement of the lever 42 along an arc-shaped trajectory and the pushing of the moving part 3, there will be no spatial interference between the pushing device 4 and the transition seat 2 and the moving part 1, guaranteeing the normal operation of the pushing device 4.

[0044] Based on the aforementioned mover supply device, this application further proposes a magnetoresistive accelerator, including a power supply (not shown), a drive coil assembly 5, and the aforementioned mover supply device. The drive coil assembly 5 includes a guide tube 51, with multiple isolation plates 52 disposed on the outer wall of the guide tube 51. A wire 53 is disposed between any two isolation plates 52, and the wire 53 is wrapped around the outer wall of the guide tube 51 and connected to the power supply. Thus, the power supply discharges to the wire 53 to generate electromagnetic force, which pulls the mover 3 inside the guide tube 51 to gradually accelerate along the guide tube 51, achieving the accelerated movement of the mover 3. Preferably, the power supply is a pulse power supply, such as a pulse capacitor, which can directly adopt existing technology and will not be elaborated further.

[0045] The isolation plate 52 and the wire 53 can be glued to the outer wall of the guide tube 51. The isolation plate 52 is a non-metallic insulating material. The spacing between two adjacent isolation plates 52 is used to determine the length of the wire 53 and to create a gap between adjacent wires 53.

[0046] In addition, the magnetoresistive accelerator also includes a housing 6. The transition seat 2, the pushing device 4, and the drive coil assembly 5 are all fixedly connected to the housing 6, for example, by fasteners such as screws, so as to ensure that the positions of each component are relatively fixed. In particular, it ensures that the positions of the transition seat 2 and the guide tube 51 are fixed, so that the moving chamber 1 is installed in the transition seat 2. Through the assembly and limiting of the transition seat 2, it avoids that either the moving chamber 1 or the guide tube 51 will be offset or misaligned, and can further ensure the coaxiality of the outlet 15 of the moving chamber 1 and the guide tube.

[0047] For the mover supply device and the entire magnetoresistive accelerator, the mover compartment 1 is mainly used for storing and continuously driving the mover 3. It is recommended that the mover compartment 1 be made of non-metallic material. The advantages of using a mover compartment for mover supply are its relatively simple structure, reliable mover supply, and convenient and quick mover replacement. The transition seat 2 is recommended to be designed as a frame structure to guide and limit the movement of the mover compartment 1, and to connect and assemble with the guide tube 51. This allows the inlet section 511 of the guide tube 51 to guide and engage with the outlet section 19 (guide notch 17) of the mover compartment 1, providing a transitional connection for the mover 3 to smoothly enter the drive coil assembly 5 from the mover compartment 1. The functions of the drive coil assembly are as follows: the mover 3 is a moving part that can generate kinetic energy under the action of the drive coil assembly 5; the main function of the pusher 4 is to push the mover 3 forward to the optimal initial position; the drive coil assembly 5 is the core component for generating a magnetic field, which generates a change in magnetic field by discharging the pulse capacitor to the drive coil assembly 5 in stages, thereby driving the mover 3 to move; at the same time, the guide tube 51 in the drive coil assembly 5 can provide guidance for the mover 3; the outer shell 6 can be made of non-metallic material and formed by 3D printing or injection molding process, and its main function is to provide support and fixation for components such as the transition seat 2, the pusher 4, and the drive coil assembly 5.

[0048] In this application, the mover exit tube of the magnetoresistive accelerator is a smoothbore type. For the working process of the magnetoresistive accelerator, the movers 3 are inserted one by one into the mover chamber body 12 through the upper end hole structure (i.e., outlet 15 and guide notch 17) of the mover chamber 1. The spring 13 is compressed, and the mover chamber 1 is inserted into the transition seat 2. At this time, the inlet section 511 of the guide tube 51 contacts the uppermost mover 3, providing guidance for the mover 3. After the pushing device 4 is energized, the lever 42 rotates. After the lever 42 pushes the mover 3, the lever returns to its initial position. Because the lever 42 pushes the lower part of the mover 3, the thrust is tilted upwards, ensuring the movement... Mover 3 remains in contact with the inlet section 511 and moves along the inlet section 511 to reach the optimal initial position. At this time, the uppermost mover 3 still has partial contact with the other mover 3 below it, ensuring that the position of the uppermost mover 3 will not slip under the elastic force of the spring 13. When the power supply discharges to the drive coil assembly 5, an electromagnetic force is generated and pulls the uppermost mover 3 to gradually accelerate along the guide tube 51. At the same time, the lower mover 3 will move upward under the action of the spring 13, repeating the same process to realize the mover supply and acceleration movement, which can ensure the continuity and smoothness of the mover supply process.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
