Description

Technical Field

[0001] This invention relates to the field of synchrotron radiation and free-electron laser undulator technology, and more particularly to an auxiliary mounting mechanism and mounting method for a permanent magnet block of an undulator. Background Technology

[0002] In the fields of synchrotron radiation and free-electron lasers, most light sources originate from an insert—an undulator consisting of periodically arranged permanent magnets. Depending on the function of the undulator, the magnet array is divided into two rows (planar undulator) or four rows (elliptical polarized undulator). The array length ranges from approximately 1000 mm to 5000 mm. There is a magnetic force between the permanent magnets and adjacent magnets in the undulator array. Due to differences in the magnetic field strength and position of the magnets, the magnitude and direction of the magnetic force vary, with the largest force reaching tens of kilograms.

[0003] In a quasi-periodic magnetic field oscillator, some magnetic blocks are positioned at a lower height than their adjacent blocks. Currently, the installation method involves first installing all magnetic blocks as normal, then adjusting with padding. Once the magnetic field configuration meets the requirements, these magnetic blocks, along with their supports, are removed. The supports are then replaced with lower-position supports before being reinstalled in their original positions.

[0004] Due to the presence of magnetism, installing and replacing magnetic blocks is an extremely difficult and dangerous task. Without the assistance of an installation mechanism, installers must be exceptionally careful to slowly push the magnetic blocks and brackets into the designated positions along a specific direction. Even the slightest mistake can easily result in collisions and damage to the magnetic blocks, and could also cause personal injury. This is especially true for oscillators with strong magnetic forces, which may be impossible to install and replace manually.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0032] In another aspect of the present invention, a method for installing a permanent magnet block of an undulator is also provided, which uses an auxiliary installation mechanism as described in any of the above technical solutions for installation, and includes the following steps:

[0033] Step 1) Secure the auxiliary installation mechanism:

[0034] The auxiliary mounting mechanism, which does not have the magnetic block adjustment bracket installed, is fixed to the magnetic block mounting base plate;

[0035] Step 2) Adjust the working position of the auxiliary installation mechanism:

[0036] The horizontal drive assembly and the vertical drive assembly are used to move the magnetic block gripping plate away from the installed magnetic block array;

[0037] Step 3) Fix the magnetic block adjustment bracket:

[0038] The magnetic block adjustment bracket, on which the magnetic block to be installed is fixed, is fixed to the magnetic block gripping plate;

[0039] Step 4) Install the magnetic block adjustment bracket:

[0040] Then, through the horizontal drive assembly and the vertical drive assembly, the magnetic block adjustment bracket and the magnetic block to be installed are transported to the magnetic block mounting base plate of the undulator for positioning and installation.

[0041] Step 5) Reset the auxiliary installation mechanism:

[0042] Release the fixed connection between the magnetic block gripping plate and the installed magnetic block adjustment bracket, and use the horizontal drive component and the vertical drive component to move the magnetic block gripping plate away from the installed magnetic block array again. Then repeat steps 3) and 4) to continue installing the remaining magnetic blocks.

[0043] In some embodiments, the installation method specifically includes:

[0044] In step 1), fixing holes are machined at intervals on the horizontal guide rail base plate according to the screw hole positions on the magnetic block mounting base plate, and the auxiliary mounting mechanism is fixed to the magnetic block mounting base plate by fixing screws at the fixing holes;

[0045] In step 2), the vertical drive assembly is first manually driven by the vertical drive handwheel to raise the magnetic block gripping plate to the highest position; then the linear motor is started, and the vertical drive assembly and the magnetic block gripping plate are moved by the horizontal drive assembly to a position away from the installed magnetic block array on the magnetic block mounting base.

[0046] In step 3), the required number of magnetic block adjustment brackets are fixed to the magnetic block gripping plate at the mounting holes using mounting screws.

[0047] In step 4), the linear motor is first started, and the magnetic block adjustment bracket is moved above the installation position by the horizontal drive assembly. Then, the vertical drive assembly is manually driven by the vertical drive handwheel to lower the magnetic block adjustment bracket to the installation position. When the magnetic block adjustment bracket is not completely aligned with the installation position of the magnetic block mounting base, the horizontal drive assembly is manually driven by the manual drive disc to finely adjust the front and rear position of the magnetic block bracket. At the same time, the vertical drive assembly is manually driven by the vertical drive handwheel to press the magnetic block adjustment bracket into place. After positioning, the magnetic block adjustment bracket is fixed to the magnetic block mounting base with mounting screws through the through holes on the magnetic block gripping plate.

[0048] In step 5), loosen the mounting screws at the mounting holes on the magnetic block gripping plate, manually drive the vertical drive assembly to lift the magnetic block gripping plate to its highest position, and start the linear motor to move the magnetic block gripping plate to a position away from the installed magnetic block array, thus completing the reset; when repeatedly installing the remaining magnetic blocks, according to the thickness of the magnetic blocks, after every 3 to 5 blocks are installed, reposition the entire auxiliary mounting mechanism on the fixed position on the magnetic block mounting base plate.

[0049] According to the auxiliary installation mechanism and method for undulator permanent magnets of the present invention, on the one hand, the magnetic block gripping plate can be pulled further and higher using horizontal and vertical drive components, and then the magnetic block adjusting bracket can be fixed on the magnetic block gripping plate, so that the magnetic block to be installed can be freed from the strong attraction of the undulator magnet array, making the installation of the undulator permanent magnet safer and more convenient. On the other hand, by using horizontal and vertical drive components to transport the magnetic block adjusting bracket to the undulator's magnetic block mounting base plate for positioning and installation after the magnetic block adjusting bracket is fixed, the installation efficiency and accuracy of the undulator permanent magnet are greatly improved, especially suitable for large quasi-periodic undulator magnets.

[0103] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0104] In related technologies, when installing permanent magnets for undulators, the lack of auxiliary mechanisms often leads to difficulties in accurately installing the magnets in the required positions due to the strong attraction between the magnets being installed and adjacent magnets. This can easily damage the magnets or cause injury to workers.

[0105] In view of this, the embodiments of this application aim to provide an auxiliary installation mechanism 10 and installation method for undulator permanent magnets, by setting up a horizontal drive component 11, a vertical drive component 12, a magnet gripping plate 13, and a magnet adjusting bracket 14. Firstly, the horizontal drive component 11 and the vertical drive component 12 are used to pull the magnet gripping plate 13 further away and higher, and then the magnet adjusting bracket 14 carrying the magnet to be installed 31 is fixed on the magnet gripping plate 13, allowing the magnet to be installed 31 to escape the strong attraction of the undulator magnet array, thus improving the safety and convenience of undulator permanent magnet installation. Secondly, after the magnet adjusting bracket 14 is fixed, the horizontal drive component 11 and the vertical drive component 12 continue to transport the magnet adjusting bracket 14 to the undulator's magnet mounting base plate 20 for positioning and installation, thereby greatly improving the installation efficiency and accuracy of the undulator permanent magnets, especially suitable for large quasi-periodic undulator magnets. Therefore, the above-mentioned problems are solved.

[0106] The following is based on Figures 1-19 The auxiliary mounting mechanism 10 for the undulator permanent magnet of the present invention will be described in detail.

[0107] Please refer to Figure 1-4 An auxiliary mounting mechanism 10 for a permanent magnet of an undulator provided in this embodiment of the invention includes a horizontal drive assembly 11, a vertical drive assembly 12, a magnet gripping plate 13, and a magnet adjusting bracket 14. Specifically: the horizontal drive assembly 11 is detachably fixed to the magnet mounting base 20 of the undulator; the vertical drive assembly 12 is fixed to the horizontal drive assembly 11 and can move closer to or further away from the mounted magnet array 32 on the magnet mounting base 20 in the horizontal direction as the horizontal drive assembly 11 moves relative to the mounted magnet array 32 on the magnet mounting base 20; the magnet gripping plate 13 is fixed to the vertical drive assembly 12 and can move closer to or further away from the mounted magnet array 32 on the magnet mounting base 20 in the vertical direction as the vertical drive assembly 12 moves relative to the mounted magnet array 32 on the magnet mounting base 20; and the magnet adjusting bracket 14 is used to load the mounted magnet 31 and is detachably fixed to the magnet gripping plate 13.

[0108] In use, the auxiliary installation mechanism 10 of this embodiment utilizes the coordinated operation of the horizontal drive component 11 and the vertical drive component 12: first, the auxiliary installation mechanism 10 is moved away from the installed magnetic block array 32 of the oscillator, and the installation of the magnetic block 31 along with the magnetic block adjustment bracket 14 on the magnetic block gripping plate 13 is completed at this position; then, the auxiliary installation mechanism 10 is moved closer to the magnetic block installation position on the magnetic block mounting base plate 20 of the oscillator, and the positioning and installation of the magnetic block 31 along with the magnetic block adjustment bracket 14 on the magnetic block mounting base plate 20 is completed at this position.

[0109] Reference Figures 5 to 8 The horizontal drive assembly 11 of this embodiment may include a horizontal guide rail base plate 111, a non-magnetic horizontal guide rail pair 112, a horizontal slide plate 113, a drive connecting plate 114, a limit switch 115, a limit switch toggle block 116, a linear motor 117, and a manual drive disk 118; wherein,

[0110] The horizontal guide rail base plate 111 is detachably fixed to the magnetic block mounting base plate 20;

[0111] The horizontal slide plate 113 is slidably mounted on the horizontal guide rail base plate 111 via the non-magnetic horizontal guide rail pair 112, and the vertical drive assembly 12 is fixedly mounted on the horizontal slide plate 113;

[0112] The fixed end of the linear motor 117 is fixedly connected to the horizontal guide rail base plate 111 via the motor bracket 11711, and the movable end of the linear motor 117 is fixedly connected to the horizontal slide plate 113 via the drive connecting plate 114.

[0113] Limit switch 115 is fixedly mounted on horizontal guide rail base plate 111 and arranged along the direction of movement, and is controlled and connected to linear motor 117. Limit switch lever 116 is fixedly mounted on horizontal slide plate 113 and arranged corresponding to limit switch 115. Manual drive disk 118 is synchronously driven and connected to linear motor 117.

[0114] Furthermore, the linear motor 117 can be a Hayden-Korck linear motor assembly, including a motor body 1171, a non-magnetic lead screw 1172, and a backlash-free nut 1173; wherein,

[0115] The motor body 1171 is fixedly mounted as the fixed end via the motor bracket 11711. The non-magnetic lead screw 1172 is the movable end of the motor body 1171, and is fixedly connected to the horizontal slide plate 113 via the connector 1172-1. The backlash-free nut 1173 is threadedly connected to the non-magnetic lead screw 1172. Both the motor body 1171 and the manual drive disk 118 are driven by the backlash-free nut 1173. Starting the motor body 1171 or operating the manual drive disk 118 can move the horizontal slide plate 113 back and forth.

[0116] In practice, the manual drive disc 118 is mounted on the backlash-free nut 1173. Therefore, in addition to operating the limit switch 115 to drive the motor, manually rotating the manual drive disc 118 can also drive the non-magnetic lead screw 1172 forward or backward. More specifically, when the motor body 1171 is running, it can drive the horizontal slide plate 113 to move axially through the lead screw-nut transmission structure; at the same time, it can also drive the backlash-free nut 1173 to rotate through the manual drive disc 118, thereby realizing the movement of the horizontal slide plate 113.

[0117] In some embodiments, the non-magnetic horizontal guide rail assembly 112 can be a non-magnetic guide rail component (e.g., IGUS brand or similar commercially available products), including a horizontal aluminum guide rail 1121, a horizontal aluminum slider 1122, and a first nylon anti-friction bushing 1123; wherein...

[0118] A horizontal aluminum guide rail 1121 is fixedly mounted on the top of the horizontal guide rail base plate 111, a horizontal aluminum slider 1122 is fixedly mounted on the bottom of the horizontal slide plate 113, the horizontal aluminum slider 1122 is slidably connected to the horizontal aluminum guide rail 1121, and a first nylon anti-friction bushing 1123 is disposed between the horizontal aluminum slider 1122 and the horizontal aluminum guide rail 1121.

[0119] In practice, the horizontal slide plate 113 slides back and forth on the non-magnetic horizontal guide rail pair 112. During operation, the linear motor 117 or the manual drive disc 118 can be started to drive the horizontal slide plate 113 to move back and forth on the non-magnetic horizontal guide rail. The first nylon anti-friction bushing 1123 can reduce friction loss during sliding and ensure smooth sliding.

[0120] Reference Figures 9 to 11 The vertical drive assembly 12 of this embodiment may include a vertical guide rail base plate 121, a non-magnetic vertical guide rail pair 122, a vertical slide plate 123, an upper slewing bearing 124, a lower slewing bearing 125, a vertical drive screw 126, a vertical drive block 1271, a vertical drive nut 127, a slewing bearing seat 1241, and a vertical drive handwheel 128.

[0121] The vertical guide rail base plate 121 is fixedly mounted on the side of the horizontal slide plate 113 facing the installed magnetic block array 32. The vertical slide plate 123 is slidably mounted on the vertical guide rail base plate 121 via the non-magnetic vertical guide rail pair 122. The magnetic block gripping plate 13 is detachably fixedly mounted on the vertical slide plate 123.

[0122] On the side of the vertical guide rail base plate 121 opposite to the installed magnetic block array 32, the vertical drive nut 127 is fixedly mounted on the vertical slide plate 123 after passing through the vertical drive block 1271 through a clearance groove extending in the vertical direction on the vertical guide rail base plate 121 (that is, a clearance groove is pre-cut in the vertical guide rail base plate to leave space for the vertical drive block 1271 to move vertically and avoid structural interference between the vertical drive block 1271 and the vertical guide rail base plate 121 when it moves). The upper rotary bearing 124 is fixedly mounted on the vertical guide rail base plate 121 through the rotary bearing seat 1241, and the lower rotary bearing 125 is directly installed by drilling holes in the horizontal slide plate 113. The upper end of the vertical drive screw 126 is fixedly connected to the vertical drive handwheel 128, and the lower end of the vertical drive screw 126 is sequentially connected to the upper rotary bearing 124, the vertical drive nut 127, and the lower rotary bearing 125. Rotating the vertical drive handwheel 128 can drive the vertical slide plate 123 to move up and down.

[0123] Furthermore, the non-magnetic vertical guide rail pair 122 in this embodiment of the invention can also be a non-magnetic guide rail assembly (e.g., IGUS brand or similar commercially available products), including a vertical aluminum guide rail 1221, a vertical aluminum slider 1222, and a second nylon anti-friction bushing 1223; the vertical aluminum guide rail 1221 is fixedly mounted on the vertical guide rail base plate 121, the vertical aluminum slider 1222 is fixedly mounted on the vertical slide plate 123, the vertical aluminum slider 1222 is slidably connected to the vertical aluminum guide rail 1221, and the second nylon anti-friction bushing 1223 is disposed between the vertical aluminum slider 1222 and the vertical aluminum guide rail 1221, preferably embedded in the inner wall surface of the vertical aluminum slider 1222 and slidingly contacting it. The second nylon anti-friction bushing 1223 is an anti-friction component made of self-lubricating engineering plastic (such as polytetrafluoroethylene (Teflon) or nylon). It reduces the coefficient of friction without the need for additional lubricant, thereby reducing the movement resistance of the vertical slide plate 123 during lifting and lowering, and ensuring the ease and smoothness of vertical adjustment. In addition, the surface of the vertical aluminum guide rail 1221 is anodized to improve its surface hardness and wear resistance.

[0124] In practice, the vertical slide plate 123 slides up and down using the non-magnetic vertical guide rail pair 122. During operation, rotating the vertical drive handwheel 128 manually drives the vertical drive screw 126, causing the vertical slide plate 123 to move up and down within the vertical guide rail. The second nylon anti-friction bushing 1223 reduces friction loss during sliding, ensuring smooth sliding.

[0125] Reference Figure 12 and Figure 13The magnetic block gripping plate 13 of this embodiment may include an L-shaped magnetic block gripping plate body 131. The longitudinal plate 1311 of the magnetic block gripping plate body 131 has a connection hole 1311-1 for fixed connection with the vertical slide plate 123. The transverse plate 1312 of the magnetic block gripping plate body 131 has a U-shaped notch 1312-1 in the middle. The U-shaped notch 1312-1 provides three positioning surfaces for the placement and positioning of the magnetic block adjustment bracket 14. On the transverse plate 1312, two sets of mounting holes 1312-2 and two sets of through holes 1312-3 are symmetrically provided on both sides of the U-shaped notch 1312-1. The mounting holes 1312-2 are used for fixed connection with the magnetic block adjustment bracket 14. The through holes 1312-3 are used for the mounting screws 143 of the magnetic block adjustment bracket 14 to pass through and fix the magnetic block adjustment bracket 14 to the magnetic block mounting base plate 20.

[0126] When the magnetic block adjustment bracket 14 is loaded onto the magnetic block mounting base plate 20, the three positioning surfaces provided on the magnetic block gripping plate 13 can ensure that the magnetic block is installed in the correct position.

[0127] Reference Figure 14-18 The magnetic block adjustment bracket 14 provided in this embodiment of the invention mainly includes a magnetic block bracket 141, a fixing plate 142, mounting screws 143, a vertical adjustment wedge 144, and a horizontal adjustment screw 145. The magnetic block bracket 141 is detachably fixed to the magnetic block gripping plate 13 on the side facing the magnetic block gripping plate 13, and its side facing the magnetic block mounting base plate 20 is fixedly connected to the magnetic block mounting base plate 20 via mounting screws 143. The magnetic block 31 to be installed is detachably fixed to the magnetic block bracket 141 via the fixing plate 142. Furthermore, the vertical adjustment wedge 144 is provided between the magnetic block bracket 141 and the magnetic block mounting base plate 20, and the horizontal adjustment screw 145 is disposed between the magnetic block bracket 141 and the vertical adjustment wedge 144. The magnetic block adjustment bracket 14, through the cooperation of the vertical adjustment wedge 144 and the horizontal adjustment screw 145, realizes stepless adjustment of the magnetic block position. It has high adjustment efficiency and can continuously and accurately change the spatial attitude of the magnetic block, thereby significantly improving the overall design performance of the undulator.

[0128] A positioning pin 21 is fixedly provided on the magnetic block mounting base plate 20, and a positioning pin groove 141-1 is provided on the vertical adjustment wedge 144. The positioning pin 21 cooperates with the positioning pin groove 141-1 to position the magnetic block adjustment bracket 14 during installation.

[0129] Specifically, refer to Figure 14 and Figure 15 The adjustment mechanism of the magnetic block adjustment bracket 14 is as follows:

[0130] Vertical adjustment:

[0131] The wedge screw passes through the first tail through hole 141-2-1 of the magnetic block bracket 141 and is screwed into the end screw hole 144-1 of the vertical adjustment wedge 144; simultaneously, the wedge tightening screw is screwed into the first tail screw hole 141-3-1 of the magnetic block bracket 141 and abuts against the end face of the vertical adjustment wedge 144. By coordinating the adjustment of the wedge screw and the wedge tightening screw, the vertical adjustment wedge 144 can be driven to slide relative to each other, thereby driving the magnetic block bracket 141 together with the magnetic block 31 to be installed to achieve precise vertical adjustment.

[0132] Horizontal adjustment:

[0133] The upper horizontal adjustment screw passes through the second tail through hole 141-2-2 of the magnetic block bracket 141 and is screwed into the side screw hole of the magnetic block mounting base 20; the lower horizontal adjustment screw is screwed into the second tail screw hole 141-3-2 of the magnetic block bracket 141 and abuts against the side of the magnetic block mounting base 20.

[0134] When making horizontal inward adjustment, first pull the lower horizontal adjustment screw back to leave a movement gap, then tighten the upper horizontal adjustment screw, and the magnetic block bracket 141 can be pulled inward.

[0135] When adjusting the horizontal movement outward, first loosen the upper horizontal adjustment screw by a certain gap, and then tighten the lower horizontal adjustment screw. The reaction force generated by the lower horizontal adjustment screw against the magnetic block mounting base plate 20 can push the magnetic block support 141 and the magnetic block 31 to be installed outward.

[0136] Reference Figure 19 This invention also provides a method for installing a permanent magnet block for an undulator, using an auxiliary installation mechanism 10 for a permanent magnet block for an undulator according to the above embodiments of this invention, comprising the following steps:

[0137] 1) Fixed auxiliary installation mechanism 10:

[0138] The auxiliary mounting mechanism 10, which does not have the magnetic block adjustment bracket 14 installed, is fixed to the magnetic block mounting base plate 20.

[0139] More specifically, step 1) includes: fixing holes 111-1 are machined on the horizontal guide rail base plate 111 at intervals according to the position of the screw holes 20-1 on the magnetic block mounting base plate 20, and the auxiliary mounting mechanism 10 is detachably fixed to the magnetic block mounting base plate 20 at the fixing holes 111-1 by fixing screws.

[0140] 2) Adjust the working position of the auxiliary installation mechanism 10:

[0141] The magnetic block gripping plate 13 is moved away from the installed magnetic block array 32 by the horizontal drive component 11 and the vertical drive component 12.

[0142] More specifically, step 2) includes: first, manually driving the vertical drive assembly 12 to raise the magnetic block gripping plate 13 to the highest position by using the vertical drive handwheel 128; then, starting the linear motor 117, which drives the vertical drive assembly 12 and the magnetic block gripping plate 13 to a position away from the installed magnetic block array 32 on the magnetic block mounting base plate 20 by using the horizontal drive assembly 11.

[0143] 3) Fixed magnetic block adjustment bracket 14:

[0144] The magnetic block adjustment bracket 14, which is loaded with the installed magnetic block 31, is fixed to the magnetic block gripping plate 13.

[0145] More specifically, step 3) includes: fixing the required number of magnetic block adjustment brackets 14 to the magnetic block gripping plate 13 at one time using mounting screws in the mounting holes 1312-2. Specifically, whether one or two sets of magnetic block adjustment brackets 14 are installed at one time usually depends on the number of columns of magnetic blocks in the undulator, such as one or two columns.

[0146] 4) Install the magnetic block adjustment bracket 14:

[0147] The magnetic block adjustment bracket 14 and the magnetic block 31 to be installed are then transported to the magnetic block mounting base plate 20 of the oscillator by the horizontal drive component 11 and the vertical drive component 12 for positioning and installation.

[0148] More specifically, step 4) includes: first, starting the linear motor 117, moving the magnetic block adjustment bracket 14 above the installation position via the horizontal drive assembly 11, and then manually driving the vertical drive assembly 12 via the vertical drive handwheel 128 to lower the magnetic block adjustment bracket 14 to the installation position; when the magnetic block adjustment bracket 14 is not fully aligned with the installation position of the magnetic block mounting base 20 (for example, the positioning pin groove 141-1 on the vertical adjustment wedge 144 is not fully aligned with the positioning pin 21 on the magnetic block mounting base 20), manually driving the horizontal drive assembly 11 via the manual drive disc 118 to manually fine-tune the front and rear position of the magnetic block bracket 141, and simultaneously manually driving the vertical drive assembly 12 via the vertical drive handwheel 128 to press the magnetic block adjustment bracket 14 into place; after positioning, fixing the magnetic block adjustment bracket 14 to the magnetic block mounting base 20 with mounting screws 143 through the through hole 1312-3 on the magnetic block gripping plate 13.

[0149] 5) Reset auxiliary installation mechanism 10:

[0150] Release the fixed connection between the magnetic block gripping plate 13 and the installed magnetic block adjustment bracket 14, and move the magnetic block gripping plate 13 away from the installed magnetic block array 32 again through the horizontal drive assembly 11 and the vertical drive assembly 12. Then repeat steps 3) and 4) to continue installing the remaining magnetic blocks.

[0151] More specifically, step 5) includes: loosening the mounting screws at the mounting holes 1312-2 on the magnetic block gripping plate 13, manually driving the vertical drive assembly 12 to lift the magnetic block gripping plate 13 to the highest position, starting the linear motor 117 to move the magnetic block gripping plate 13 to a position away from the installed magnetic block array 32, thus completing the reset; when repeatedly installing the remaining magnetic blocks, depending on the thickness of the magnetic blocks, every 3 to 5 blocks installed, the fixed position of the entire auxiliary mounting mechanism 10 on the magnetic block mounting base plate 20 should be moved back and repositioned.

[0152] It should be noted that, in this embodiment of the invention, the upper slewing bearing 124 and the lower slewing bearing 125 are made of bronze, the non-magnetic lead screw 1172 is made of stainless steel, and other materials not specified (including the vertical guide rail base plate, vertical slide plate, bearing seats, and fixing connectors, etc.) are all made of 6061-T6 aluminum. The selection of the above materials follows the overall design principle of this invention, namely, all components adjacent to the magnetic block installation area or potentially entering the magnetic field zone are made of non-magnetic materials to avoid interference with the positioning accuracy of the magnetic block due to magnetic attraction of ferromagnetic materials during installation, or even safety accidents such as magnetic block collisions or personnel injuries caused by sudden increases in magnetic force.
