Description

TECHNICAL FIELD

[0001] The present application relates to the field of mechanical equipment, in particular to a magnetron anode antenna correction device. BACKGROUND

[0002] The anode of a magnetron is a complex resonant system, and the anode block is composed of many small resonant cavities. They are electromagnetically coupled with each other. The anode block is a frequency-selective magnetron. Electrons emitted from the cathode, under the action of a microwave direct current field, move in a cycloidal trajectory during the process of flowing from the cathode to the anode in an angular direction. Under the condition that the high-frequency field is synchronized with the electron cloud, the electron trajectory is lifted in the direction of the anode, forming an electron spoke. In the spoke, the electrons convert potential energy into high-frequency field energy when the high-frequency field is synchronized, so that the amplitude of the high-frequency field increases. After the magnetron is started, the direct current energy stored in the resonant cavity is converted into super-high frequency energy, which is output through a waveguide to provide a microwave energy source with sufficient power. The anode antenna and the anode cylinder of the magnetron need to be coaxial in the center during assembly to maintain the perpendicularity of the constant magnetic field and the constant electric field. However, during assembly, the anode antenna often deviates from the central axis of the anode cylinder, resulting in poor output frequency of the magnetron. Therefore, the anode antenna of the magnetron needs to be corrected during magnetron production.

[0036] Please refer to Figure 1 and Figure 12 Embodiments of the present application disclose a correction device 100 of a magnetron anode antenna 220.

[0037] In an embodiment, as shown in Figure 1 and Figure 5 , the correction device 100 is used to correct the antenna 220 of the anode assembly 200 of the magnetron, Figure 1 The schematic diagram of the antenna 220 before correction is shown in Figure 1 , the antenna 220 before correction is vertically offset from the anode cylinder 210, and is not concentric with the anode cylinder 210; Figure 2This is a schematic diagram of the corrected antenna 220, as shown below. Figure 2 As shown; after correction, the anode vertical antenna 220 is concentric with the anode cylinder 210 and has the same direction; the anode assembly 200 includes the anode cylinder 210, the antenna 220 is disposed on the anode cylinder 210, the correction device 100 includes a fixed frame 1 and a worktable 2 disposed on the fixed frame 1, and a correction component 3 slidably disposed on the fixed frame 1. The correction component 3 is used to correct the antenna 220 so that the corrected antenna 220 and the anode cylinder 210 are concentric.

[0038] The fixed frame 1 includes a base plate 10 and two columns. A connector is slidably mounted on the end of the two columns 11 away from the base plate 10. A rotary drive structure 30 is mounted on the first connector 32, allowing the rotary drive structure 30 to move up and down along the columns 11. Multiple clamping and correction structures 31 are mounted on columns 11. The two columns 11 are arranged side by side, and the base plate 10 is horizontally positioned between the two columns 11. The worktable 2 is vertically mounted on the base plate 10. The correction assembly 3 includes a first connector 32, a rotary drive structure 30, and multiple clamping and correction structures 31. The first connector 32 can be plate-shaped or strip-shaped. The multiple clamping and correction structures 31 can be rotatably mounted on the rotary drive structure 30, and each anode cylinder 210 is coaxially opposite to each clamping and correction structure 31. That is, the center of the clamping and correction structure 31 and the center of the anode cylinder 210 are on the same axis, and the clamping and correction structure 31 is located above the anode cylinder 210. This allows the rotation drive structure 30 to not only drive the clamping and correction structure 31 to move up and down along the column 11, that is, to drive the clamping and correction structure 31 to move down along the column 11 to the periphery of the antenna 220, so that the clamping and correction structure 31 can clamp and correct the antenna 220, but also drive the clamping and correction structure 31 to rotate, thereby driving the antenna 220 to rotate to eliminate the stress after the antenna 220 is corrected. This prevents the antenna 220 from being misaligned with the anode cylinder 210 due to stress rebound after being clamped and corrected, thereby improving the correction accuracy and improving the yield of the magnetron in the future.

[0039] In this embodiment, by arranging multiple clamping correction structures 31 on the rotary drive structure 30, the correction device 100 can not only perform one-to-one correction of the anode assembly 200, but also simultaneously correct multiple groups of anode assemblies 200, improving versatility and work efficiency. Furthermore, through the cooperation of the clamping correction structures 31 and the rotary drive structure 30, the correction device 100 does not need to use a CCD camera to photograph and confirm the correction range of the antenna 220, and then control the drive assembly to correct the antenna 220 based on that correction range. This results in a compact, simple, and highly efficient correction device 100 design.

[0040] like Figure 6As shown, in an embodiment, the correction assembly 3 further comprises a fixed pressing plate 33, which is arranged on the first connecting piece 32 and located in the range of the orthographic projection of the opening of the clamping correction structure 31, that is, the parallel projection line is perpendicular to the projection plane. The fixed pressing plate 33 is used to fix and press the anode cylinder 210. In operation, the second driving piece 4 drives the correction assembly 3 to move downward, and the correction assembly 3 drives the fixed pressing plate 33 to move downward until the fixed pressing plate 33 is pressed against the end face of the anode cylinder 210. In this way, during the correction process, the displacement of the anode cylinder 210 is avoided, so that the correction accuracy is not inaccurate.

[0041] In order to further improve the stability of the anode cylinder 210, the fixed pressing plate 33 is provided with a fixed end 330 and a pressing end 331 connected with each other. The fixed end 330 is fixed on the first connecting piece 32, so that the first connecting piece 32 can drive the fixed pressing plate 33 to move towards the antenna 220. The pressing end 331 is provided with an inwardly recessed recess 332 towards the end face of the side of the anode cylinder 210. The recess 332 is pressed against the end face of the anode cylinder 210 to fix the anode cylinder 210. The antenna 220 passes through the gap 333 of the pressing end 331, so that the clamping correction structure 31 can clamp the antenna 220.

[0042] Further, as shown, Figure 6 The clamping correction structure 31 comprises a fixed piece 310 and at least two correction pieces 311 arranged in opposite directions. One side of the fixed piece 310 is fixed on the output end of the rotating correction structure, so that the rotating correction structure can drive the clamping correction structure 31 to rotate. The two correction pieces 311 arranged in opposite directions are movably arranged on the other end of the fixed frame 1. The fixed piece 310 can be a cylindrical structure, a cuboid structure or a square structure. The correction piece 311 can be a block structure. In this embodiment, the cylindrical structure is preferred, which makes the structure design of the correction device 100 compact and simple, and reduces the volume and space occupation.

[0043] In order to further improve the accuracy and convenience of the correction device 100, the correction member 311 can be set to four, and two are set to move oppositely, so that the correction device 100 can correct the antenna 220 in multiple directions in front and back, left and right directions, so that when placing the anode assembly 200, it is not necessary to pay attention to which side the antenna 220 is deviated to, and only the anode antenna 220 is placed on the workbench 2. And no matter which direction the antenna 220 deviates to, the correction member 311 opens a space when the clamping and correcting structure 31 is in the open state, which is enough to be compatible with all deformation sizes, improving the versatility of the correction device 100. And by using positive pressure gas as the driving source of the clamping and correcting structure 31, only the intake hole 312 is arranged on the fixing member 310, and then the positive pressure gas is input into the intake hole 312 to drive the clamping and correcting structure 31, avoiding that each correction block or two correction blocks correspond to one driving member, and increasing the complexity and volume of the structure.

[0044] The fixing member 310 is provided with a plurality of intake holes 312, and each intake hole 312 corresponds to each correction member 311. During work, the intake hole 312 is communicated with the external air pressure equipment, so that the external air pressure equipment can input the positive pressure body into the intake hole 312, and the positive pressure body drives the two correction members 311 to move towards each other, Figure 7 The correction state diagram of the clamping and correcting device 100 is used to clamp and correct the antenna 220. Since the clamping and correcting structure 31 and the anode cylinder 210 are coaxially arranged, when the two correction members 311 clamp the antenna 220, the axis of the antenna 220 and the axis of the anode cylinder 210 are on the same axis, that is, the correction of the antenna 220 is completed. However, since the corrected antenna 220 has stress, the stress structure of the antenna 220 is changed by rotating, so as to eliminate the stress of the antenna 220, so that the antenna 220 will not rebound to cause the antenna 220 to be eccentric with the anode cylinder 210. Since the two correction members 311 can move to clamp, the clamping and correcting structure 31 can clamp various coaxial anode assemblies 200, so that the versatility of the correction device 100 is strong.

[0045] In an embodiment, as Figure 8 and Figure 9As shown, the correction device 100 further comprises a second driving member 4 and a sliding structure 5, one end of the second driving member 4 is fixed on the side of the fixed frame 1 away from the correction assembly 3, the output end of the second driving member 4 is fixed on the first connecting member 32, the sliding structure 5 comprises a guide rail 50 and a sliding block 51, the guide rail 50 is fixed on the stand column 11, the sliding block 51 is fixed on the first connecting member 32, and the sliding block 51 is slidingly connected to the guide rail 50, so that the correction assembly 3 is connected to the fixed frame 1 through the sliding structure 5, and thus the second driving member 4 drives the first connecting member 32 to move upward or downward along the direction of the guide rail 50, when it is needed to clamp the correction antenna 220, the second driving member 4 works to drive the first connecting member 32 to move downward along the stand column 11 towards the antenna 220.

[0046] Specifically, the second driving member 4 can be a cylinder or a motor.

[0047] In an embodiment, Figure 9 As shown, the correction device 100 further comprises a buffer 6, which is arranged on the fixed frame 1 and located in the orthographic projection range of the correction assembly 3, so that when the fixed pressing plate 33 is pressed against the anode cylinder 210, the oil pressure buffer 6 is contracted, buffered and limited, ensuring that the fixed pressing plate 33 is pressed against the anode cylinder 210 without causing damage to the anode cylinder 210. The buffer 6 can be an oil pressure buffer 6, which mainly consists of a body, an axis, a bearing, an inner tube, a piston, a hydraulic shaft and a spring. When the axis is impacted by external force, it will drive the piston to extrude the hydraulic oil in the inner tube. After the hydraulic oil is pressed, it will be discharged from the oil discharge hole of the inner tube, and at the same time, the hydraulic oil discharged from the inner tube will flow back to the inner tube through the oil return hole of the inner tube. When the external force disappears, the spring will push the piston back to the starting point and wait for the next action. According to this principle, the oil pressure buffer 6 can effectively balance and stop the moving object.

[0048] In an embodiment, the rotating driving structure 30 comprises a first driving member 301 and a rotating mechanism 302, the first driving member 301 is arranged on the first connecting member 32, the first connecting member 32 is slidingly arranged on the stand column 11 of the fixed frame 1, so that the first driving member 301 is slidingly arranged on the fixed frame 1 through the first connecting member 32, the output end of the first driving member 301 is arranged on the rotating mechanism 302, and a plurality of clamping correction mechanisms are rotatably arranged on the rotating mechanism 302, so that the rotating mechanism 302 can drive the clamping correction structure 31 to rotate, thereby driving the antenna 220 to rotate to eliminate the stress of the antenna 220 after correction, avoiding the rebound of the antenna 220 after the clamping correction structure 31 is loosened, and causing the antenna 220 to be eccentric to the anode cylinder 210.

[0049] In an embodiment, as Figure 10As shown, the rotating mechanism 302 can be a rack 303 and pinion 304 transmission mechanism, at this time, the first driving member 301 can be a cylinder or a linear motor; in the embodiment, the first driving member 301 is preferably a cylinder, and the rotating mechanism 302 includes the rack 303 and a plurality of pinions 304, the rack 303 is slidably arranged on the first connecting member 32 through cooperation of the guide rail 50 and the sliding block 51, the output end of the first driving member 301 is connected with the rack 303, Figure 10 A schematic view of the working state of the first driving member 301 when the correction device 100 is in correction is shown in FIG. 6, Figure 10 As shown, so that the first driving member 301 can drive the rack 303 to move, the plurality of pinions 304 are all connected in mesh with the rack 303, each clamping and correcting structure 31 is arranged on the output shaft of each pinion 304, so that the first driving member 301 drives the rack 303 to move, the rack 303 drives the pinions 304 to rotate, the pinions 304 drive the clamping and correcting structures 31 to rotate, after the clamping and correcting structures 31 clamp and correct the antenna 220, the antenna 220 generates deformation and has stress, the clamping and correcting structures 31 are rotated to twist and correct the antenna 220, so as to eliminate the stress of the antenna 220 after correction, and avoid that the antenna 220 rebounds to the original state after the clamping and correcting structures 31 are loosened, resulting in that the antenna 220 is not concentric with the anode cylinder 210. Through the design of the rack 303 and the pinions 304, not only can a plurality of anode assemblies 200 be simultaneously corrected by arranging a plurality of pinions 304 on the rack 303, to improve universality and working efficiency, but also the structure design of the correction device 100 is compact and simple.

[0050] Further, as shown in FIGS. 7 and 8, Figure 11 and Figure 12 As shown, the correction assembly 3 further includes a connecting block 34 and an adapter plate 35, one end of the connecting block 34 is connected with the output end of the first driving member 301, the other end of the connecting block 34 is connected with the adapter plate 35, the adapter plate 35 is provided with a sliding block (not shown in the figure), the first connecting member 32 is provided with a sliding rail guide 7 corresponding to the sliding block 51, the sliding block and the sliding rail guide 7 are slidably connected, and the rack 303 is arranged on the adapter plate 35, so that the first driving member 301 drives the connecting block 34 to move at the same time as driving the adapter plate 35 and the rack 303 to move.

[0051] As shown in FIG. 9, Figure 10As shown, during calibration by the calibration device 100, one or more anode cylinders 210 requiring calibration are manually placed on the designated position on the workbench 2. The second drive unit 4 drives the first connecting member 32 to move the fixed pressure plate 33 toward the antenna 220 until the fixed pressure plate 33 presses and fixes the anode cylinder 210 onto the workbench 2. At this time, the buffer 6 set on the first connecting member 32 retracts, buffers, and limits the pressure plate while pressing the anode cylinder 210, ensuring that the fixed pressure plate 33 presses the anode cylinder 210 but does not damage it. After the anode cylinder 210 is fixed, positive pressure is introduced into the air inlet 312. Gas, under positive pressure, drives the multiple correction elements 311 of the clamping and correction structure 31 to contract and clamp the antenna 220. At this time, the clamping and correction structure 31 clamps and corrects the antenna 220, and the anode cylinder 210 is in a fixed state and will not be displaced. The first driving element 301 drives the rotating mechanism 302 to rotate, and the rotating mechanism 302 drives the clamping and correction structure 31 to rotate, so that the clamping and correction structure 31 performs torsional correction on the antenna 220, changes the stress structure of the antenna 220, eliminates the stress of the corrected antenna 220, and prevents the antenna 220 from rebounding back after the clamping and correction structure 31 is released, which would cause the antenna 220 to be misaligned with the anode cylinder 210. If there is only clamping correction without rotational torsional correction, the antenna 220 will generate stress due to deformation after clamping and correction. The stress will cause the antenna 220 to rebound back when the clamping and correction structure 31 is released, which cannot guarantee that the antenna 220 is completely concentric with the anode cylinder 210. Therefore, the antenna 220 corrected by the correction device 100 of the present invention has a higher yield.

[0052] like Figure 11 As shown, after the calibration device 100 calibrates: the first driving member 301 stops working, thereby causing the clamping calibration structure 31 to stop rotating, the gear 304 or turbine approaches the left side of the calibration device 100, and the second driving member 4 drives the calibration assembly 3 to move upward, and is in the restoration state.

[0053] Compared to existing technologies, this invention, by setting multiple clamping and correction structures 31, not only achieves one-to-one correction but also allows for simultaneous correction of multiple groups, improving work efficiency. By setting the clamping and correction structure 31 in the form of a gripper, the opening space of the correction component 311 when the clamping and correction structure 31 is in the open state is sufficient to accommodate all deformation dimensions, improving the versatility of the correction device 100. By adopting pure mechanical correction using the clamping and correction structure 31 and the rotary drive structure 30, the correction yield is improved, and the correction device 100 has good stability and low maintenance costs. For the need to correct multiple coaxial magnetrons, there is no need to customize them one by one, which can greatly save costs.

[0054] The above examples are only used to illustrate the technical solutions of the present application, but not to limit the present application; the technical features in the above examples or different examples can also be combined, the steps can be implemented in any order, and there are many other changes of different aspects of the present application as described above, which are not provided in details for simplicity; although the present application has been described in detail with reference to the foregoing examples, it should be understood by those of ordinary skill in the art that the technical solutions recorded in the foregoing examples can be modified, or some technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
