Description

Technical Field

[0001] This utility model belongs to the field of magnet assembly technology, specifically relating to an mounting bracket for assembling strong magnetic blocks. Background Technology

[0002] The current method for magnetizing and assembling magnets involves first cutting non-magnetic raw materials to the required shape and size, and then feeding them into a magnetizer for magnetization. However, due to the limited volume of the magnetizer's working area, it is impossible to magnetize large materials at once. If a magnet exceeding the volume of the magnetizer's working area is required, several non-magnetic raw materials must be magnetized separately before being assembled with magnets.

[0003] The following problems exist with magnetic assembly:

[0004] 1. Strong magnets have strong magnetism, but the material is brittle and has a smooth surface. When using tools to hold strong magnets during assembly, excessive clamping force can damage the magnets, while insufficient clamping force will result in unstable holding. This is because when two strong magnets are brought close together, they are attracted to each other by the magnetic field, causing the magnets to easily slip out of the tool's grip and collide and stick together, leading to cracks and damage to the edges of the magnets. Similarly, when assembling strong magnets manually, there is a risk that two magnets will collide and pinch fingers, or damage the magnets. Furthermore, collisions between strong magnets can cause them to shatter, scattering debris and posing a safety hazard.

[0005] 2. Because it is not possible to drill holes in strong magnets, how to stably clamp strong magnets is a challenge in assembling with magnets.

[0006] 3. Due to the influence of magnetic force and friction, it is difficult to separate two strong magnets that are tightly attracted together. Utility Model Content

[0007] The technical problem to be solved by this utility model is to provide a mounting bracket for splicing strong magnetic blocks, so that strong magnetic blocks can be spliced ​​or separated safely and controllably, in light of the current state of the technology.

[0008] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a mounting bracket for splicing strong magnetic blocks, comprising:

[0009] The installation platform has an upward-facing countertop;

[0010] Its features are:

[0011] The platform is provided with a slide rail, and the extension direction of the slide rail is defined as the left and right direction;

[0012] The mounting bracket also includes:

[0013] Two supports are provided: a fixed support and a movable support. The fixed support is located on one side of the slide rail, and its interior is hollow, forming a first chamber for constraining a first strong magnetic block to be assembled. The first chamber has a first opening on the side facing the slide rail to expose the magnetic pole surface of the first strong magnetic block. The movable support is movably mounted on the slide rail, and its interior is hollow, forming a second chamber for constraining a second strong magnetic block to be assembled. The second chamber has a second opening on the side facing the first chamber to expose the magnetic pole surface of the second strong magnetic block.

[0014] The drive mechanism, whose output end acts on the movable bracket, is used to drive the movable bracket to move left and right to a first position or a second position. In the first position, the second opening of the second chamber is opposite to and adjacent to or fits with the first opening of the first chamber, so that the magnetic pole surface of the second strong magnet in the second chamber can be magnetically attracted to the magnetic pole surface of the first strong magnet in the first chamber. In the second position, the second opening of the second chamber is offset from the first opening of the first chamber.

[0015] During assembly, a lateral advancement method is used to constrain the first strong magnetic block to a fixed position on the fixed bracket. The movable bracket, carrying the second strong magnetic block, moves along the extension direction of the magnetic pole surface of the first strong magnetic block, gradually approaching it. As the movable bracket moves further, the magnetic pole surface of the second strong magnetic block within the movable bracket moves in contact with the magnetic pole surface of the first strong magnetic block, until the movable bracket moves to the first position, at which point the second strong magnetic block within the movable bracket aligns with the first strong magnetic block within the fixed bracket, completing the assembly of the two strong magnetic blocks. During the assembly process, the design of the first chamber within the fixed bracket, the second chamber within the movable bracket, and the direction of movement of the movable bracket stably constrain the strong magnets, preventing them from rotating and flying out of their brackets due to magnetic force. This allows for the safe and controllable assembly of strong magnets using this invention.

[0016] Conversely, when it is necessary to separate two strong magnets that are attracted together, simply move the movable support from the first position away from the fixed support to the second position for easy operation.

[0017] The strong magnetic block described in this invention refers to a magnet with a large magnetic force (such as a magnet with a magnetic force of 2000 gauss or more), making it impossible for a person to assemble it manually by hand. To further prevent the strong magnet from rotating and flying out of its support during assembly due to magnetic force, preferably, a vertically arranged, left-right extending fixed baffle is also included. This baffle and the fixed support are arranged side-by-side on the mounting platform, and the baffle's surface blocks the second opening of the second chamber in the second position. That is, the fixed baffle prevents the second strong magnetic block in the second chamber from flying out of the second opening. Since the fixed baffle and the fixed support are arranged to the left and right, the design of the fixed baffle does not affect the alignment of the second opening of the movable support with the first opening of the fixed support.

[0018] More preferably, it also includes a vertically arranged, left-right extending movable baffle, which is arranged side-by-side with the movable support in the left-right direction on the slide rail and can move with the movable support. In the second position, the movable baffle is located between the movable support and the fixed support and can block the first opening of the first chamber as the movable support moves towards the first position. That is, the movable baffle can prevent the first strong magnetic block in the first chamber from flying out of the first opening. And because the movable support and the movable baffle are arranged on the left and right, the design of the movable baffle does not affect the alignment of the second opening of the movable support and the first opening of the fixed support.

[0019] Furthermore, the surface of the fixed baffle is substantially on the same vertical plane as the edge of the first opening of the first chamber;

[0020] In the second position, the surface of the fixed baffle and the surface of the corresponding movable baffle are in contact;

[0021] The surface of the movable baffle is substantially on the same vertical plane as the edge of the second opening of the second chamber.

[0022] The term "basic" means that the two surfaces can be on the same vertical plane or slightly deviate from each other in the front-back direction.

[0023] In the above scheme, in order to better constrain the strong magnetic block, preferably, each of the brackets includes:

[0024] Top wall;

[0025] The side walls extending downward from the left and right sides of the top wall have their lower edges folded in opposite directions to form folded edges. When the bracket is a fixed bracket, the folded edges are constrained to the table surface by the first fastener. When the bracket is a movable bracket, the folded edges are constrained to the slide plate by the first fastener. The slide plate is movably mounted on the slide rail.

[0026] The back plate is positioned between the two side walls in a way that allows it to move back and forth, so as to form a cavity with one side open and the other side closed in the front-back direction with the top wall and the side walls.

[0027] In this invention, the back plate can be adjusted in position according to the thickness of the strong magnetic block in the front-back direction, so that the magnetic pole face of the strong magnetic block is just exposed at the opening of the chamber. At the same time, it can also constrain the position of the strong magnetic block.

[0028] Furthermore, the back panel includes an L-shaped arrangement of vertical and horizontal plates. The surfaces of the vertical plates are arranged one in front of the other between two side walls. The horizontal plate is provided with a limiting hole extending forward and backward. When the support is a fixed support, the horizontal plate passes downward through the limiting hole via a second fastener and is connected to the platform. When the support is a movable support, the horizontal plate passes downward through the limiting hole via a second fastener and is connected to the slide plate.

[0029] In the above solutions, the driving mechanism can be an existing telescopic mechanism such as a hydraulic cylinder or an electric cylinder. Preferably, the driving mechanism includes:

[0030] A lead screw and nut assembly, wherein the lead screw extends to the left and right, and the first end of the lead screw is constrained to the movable bracket in a manner that allows it to rotate about its central axis; the nut in the lead screw and nut assembly is constrained to the mounting platform.

[0031] A handwheel connected to the second end of the lead screw for driving the lead screw to rotate.

[0032] Preferably, it also includes a vertically arranged, front-to-back extending mounting plate, the mounting plate being located outside the second cavity of the movable bracket and constrained together with the movable bracket, and the mounting plate having mounting holes penetrating the plate thickness;

[0033] The first end of the lead screw passes through the mounting hole, and two nuts are threaded to the outer circumference of the first end of the lead screw. The two nuts are located on the left and right sides of the mounting plate.

[0034] Furthermore, the nut is configured to rotate about a pivot extending back and forth about its lower side;

[0035] The mounting plate has a top opening for the mounting hole and is provided with a valve stem that can open or close the opening.

[0036] When the movable bracket is far from the fixed bracket, it can be manually pushed to move. When the movable bracket is close to the fixed bracket, the screw is rotated to constrain the first end of the screw into the mounting hole of the mounting plate through two nuts. Then, the top opening of the mounting hole is closed by the valve stem. The movable bracket can be moved by rotating the handwheel. The cooperation structure between the mounting plate and the screw allows the drive mechanism to stably drive the movable bracket to move.

[0037] In the above solutions, the slide can be an existing track structure. Preferably, the slide is a strip-shaped hole extending to the left and right; the screw rod passes through the strip-shaped hole and is connected to the movable bracket.

[0038] Compared with existing technologies, the advantages of this invention are as follows: Through the design of the fixed bracket, movable bracket, and driving mechanism, during assembly, a lateral thrust method is used to constrain the first strong magnetic block to a fixed position on the fixed bracket. The movable bracket, carrying the second strong magnetic block, moves along the extension direction of the magnetic pole surface of the first strong magnetic block, gradually approaching it. As the movable bracket moves further, the magnetic pole surface of the second strong magnetic block within the movable bracket moves in contact with the magnetic pole surface of the first strong magnetic block until the movable bracket reaches the first position, at which point the second strong magnetic block within the movable bracket aligns with the first strong magnetic block within the fixed bracket, completing the assembly of the two strong magnetic blocks. During the assembly process, the design of the first chamber within the fixed bracket, the second chamber within the movable bracket, and the direction of movement of the movable bracket stably constrain the strong magnets, preventing them from rotating and flying out of their brackets due to magnetic force. This allows the present invention to safely and controllably assemble strong magnets.

[0039] Conversely, when it is necessary to separate two strong magnets that are attracted together, simply move the movable support from the first position away from the fixed support to the second position for easy operation. Attached Figure Description

[0045] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0046] like Figures 1-5As shown, this is a preferred embodiment of a mounting frame for splicing strong magnetic blocks according to the present invention. The mounting frame includes a mounting platform 1, a bracket 2, a drive mechanism 3, a fixed baffle 4, a movable baffle 5, a sliding plate 6, and a mounting plate 7.

[0047] The mounting platform 1 has an upward-facing tabletop 10, and the tabletop 10 has a horizontally extending strip hole in the center as a slide 11.

[0048] The aforementioned slide plate 6 is placed flat on the tabletop 10, and the rods of the two screws 8, one on the left and one on the right, pass through the strip holes and are connected to the slide plate 6, so that the slide plate 6 is constrained on the tabletop 10 in a way that allows it to move left and right.

[0049] There are two supports 2: a fixed support 21 and a movable support 22. The fixed support 21 is mounted on the platform 10 and located behind the slide rail 11 and the slide plate 6. The fixed support 21 has a hollow interior forming a first chamber 210 for constraining the first strong magnetic block 91 to be assembled. The front of the first chamber 210 has a first opening 211 to expose the magnetic pole face of the first strong magnetic block 91. The movable support 22 is mounted on the slide plate 6. The movable support 22 has a hollow interior forming a second chamber 220 for constraining the second strong magnetic block 92 to be assembled. The rear of the second chamber 220 has a second opening 221 to expose the magnetic pole face of the second strong magnetic block 92. In this embodiment, the two supports 2 have the same structure, each including a top wall 23, two side walls 24, and a back plate 25. The top wall 23 extends to the left and right. Two side walls 24 extend downward from the left and right sides of the top wall 23, respectively. The lower edges of the two side walls 24 are folded and extended in opposite directions to form folded edges 240. When the bracket 2 is a fixed bracket 21, the two folded edges 240 are constrained to the table surface 10 by their respective first fasteners 241 (existing screws). When the bracket 2 is a movable bracket 22, the two folded edges 240 are constrained to the slide plate 6 by their respective first fasteners 241 (existing screws). The back plate 25 is disposed between the two side walls 24 in a way that allows it to move back and forth, so as to form a cavity with one side open and the other side closed in the front-back direction between the top wall 23 and the side walls 24. The back plate 25 includes an L-shaped vertical plate 251 and a horizontal plate 252. The vertical plate 251 is arranged one in front of the other between the two side walls 24. The horizontal plate 252 is provided with a limiting hole 253 extending forward and backward. When the bracket 2 is a fixed bracket 21, the horizontal plate 252 passes downward through the limiting hole 253 through the second fastener 254 (which is an existing screw) and is connected to the table surface 10. When the bracket 2 is a movable bracket 22, the horizontal plate 252 passes downward through the limiting hole 253 through the second fastener 254 (which is an existing screw) and is connected to the slide plate 6, so that the back plate 25 is constrained on the slide plate 6 or the table surface 10 and its position can be adjusted forward and backward.

[0050] The aforementioned fixed baffle 4 extends left and right and is vertically installed on the platform 10 of the mounting platform 1 (the fixed baffle 4 is constrained to the platform 10 of the mounting platform 1 by screws or other fasteners) on the right side of the fixed bracket 21. The front surface of the fixed baffle 4 is substantially on the same vertical plane as the edge of the first opening 211 of the fixed bracket 21, and the left edge of the front surface of the fixed baffle 4 is located adjacent to the edge of the first opening 211 of the fixed bracket 21.

[0051] The aforementioned movable baffle 5 extends to the left and right and is vertically installed on the slide plate 6, on the right side of the movable bracket 22, and the rear side panel of the movable baffle and the edge of the second opening 221 of the movable bracket 22 are basically on the same vertical plane.

[0052] The output end of the aforementioned drive mechanism 3 acts on the movable bracket 22, driving the movable bracket 22 to move left or right to the first position or the second position. For example... Figure 4 , 5 As shown, in the first position, the second opening 221 of the second chamber 220 is opposite to the first opening 211 of the first chamber 210, causing the magnetic pole face of the second strong magnet 92 in the second chamber 220 to be magnetically attracted to the magnetic pole face of the first strong magnet 91 in the first chamber 210. Figures 1-3 As shown, in the second position, the movable support 22 is located to the right of the fixed support 21. The second opening 221 of the second chamber 220 is offset from the first opening 211 of the first chamber 210, and the second opening 221 of the second chamber 220 is blocked by the front side panel of the fixed baffle 4. The movable baffle 5 is located between the movable support 22 and the fixed support 21, and the rear side panel of the movable baffle 5 is in contact with the front side panel of the fixed baffle 4. As the movable support 22 moves from the second position to the first position, the movable baffle 5 first gradually blocks the first opening 211 of the fixed support 21, and then gradually exposes the first opening 211 of the fixed support 21. At the same time as it is exposed, the second opening 21 of the movable support 21 gradually aligns with the first opening 211 of the fixed support 21, thereby realizing the splicing of the strong magnetic blocks 92 in the two supports 2.

[0053] To stably drive the sliding plate 6, in this embodiment, the mounting plate 7 extends forward and backward and is vertically mounted on the sliding plate 6, in front of the movable bracket 22. The mounting plate 7 has a mounting hole 70 that penetrates the plate thickness. The top of the mounting hole 70 is open and has a valve stem 71 that can open or close the opening. The valve stem 71 can be a screw extending forward and backward. Fastening nuts connected to the screw are threaded on both sides of the opening. Rotating the screw allows it to disengage from the fastening nuts and open the opening. In addition, one end of the valve stem 71 is rotatably connected to one side of the opening, and the other end is a free end, which is detachably constrained to the other side of the opening. Rotating the valve stem 71 opens the opening. The drive mechanism 3 includes a screw and nut assembly and a handwheel 33. The screw 31 in the screw and nut assembly extends left and right. The first end of the screw 31 passes through the mounting hole 70, and two nuts 34 are threadedly connected to the outer circumference of the first end of the screw 31. The two nuts 34 are located on the left and right sides of the mounting plate 7. The nut 32 in the lead screw and nut assembly is mounted on the mounting platform 1 in a manner that allows it to rotate about its lower side and extend back and forth. A handwheel 33 is connected to the second end of the lead screw 31 to drive its rotation. Thus, the rotation of the nut 32 causes the lead screw 31 to rotate up and down, thereby allowing the first end of the lead screw 31 to enter and exit the mounting hole 70. Once the first end of the lead screw 31 enters the mounting hole 70 through the top opening, the top opening can be closed by the valve stem 71, thereby constraining the first end of the lead screw 31 within the mounting hole 70 so that it can rotate about its own axis.

[0054] The steps for assembling the strong magnetic blocks in this embodiment are as follows:

[0055] 1. First, rotate the first end of the lead screw 31 upward to disengage it from the mounting hole 70, and then move the movable bracket 22 to the farthest point to the right;

[0056] 2. Fix the slide plate 6 relative to the table surface 10 of the mounting platform 1 by tightening the screws 8. Then place the first and second strong magnetic blocks to be spliced ​​into the fixed bracket 21 and the movable bracket 22 respectively (the strong magnetic blocks can enter the corresponding chamber through the opening, or the chamber can be opened by moving the back plate 25 outward to allow the strong magnetic blocks to enter the chamber).

[0057] 3. Loosen screw 8, move slide plate 6 to the left so that the first end of screw 31 is inserted into mounting hole 70 of mounting plate 7 through top opening, and then close top opening of valve stem 71.

[0058] 4. Rotate handwheel 33 to move movable bracket 22 to the left and gradually approach fixed bracket 21 until movable bracket 22 moves to the first position, thus completing the splicing of the two strong magnetic blocks. The spliced ​​strong magnetic blocks can be removed from the chamber by removing one of the back plates 25.

[0059] By reversing the steps described above, the two strong magnets that are attracted to each other can be separated.

[0060] The mounting bracket in this embodiment can be used to connect multiple strong magnetic blocks. Taking the connection of four strong magnetic blocks as an example:

[0061] The first and second strong magnetic blocks can be constrained within two supports respectively, and the first and second strong magnetic blocks can be spliced ​​together according to the above operation steps. Then, the spliced ​​first and second strong magnetic blocks and the third strong magnetic block to be spliced ​​together can be constrained within two supports respectively, and the splicing of the three strong magnetic blocks can be completed according to the above operation steps. Finally, the spliced ​​three strong magnetic blocks and the fourth strong magnetic block to be spliced ​​together can be constrained within two supports respectively, and the splicing of the four strong magnetic blocks can be completed according to the above operation steps.

[0062] Alternatively, the first and second strong magnetic blocks can be constrained within two supports respectively, and the assembly of the first and second strong magnetic blocks can be completed following the steps above. Then, the third and fourth strong magnetic blocks can be constrained within two supports respectively, and the assembly of the third and fourth strong magnetic blocks can be completed following the steps above. Finally, the assembled first and second strong magnetic blocks, as well as the assembled third and fourth strong magnetic blocks, can be constrained within two supports respectively, and the assembly of all four strong magnetic blocks can be completed following the steps above. Figure 3 As shown, Figure 3 The magnets with different cross-sections inside each bracket 2 can be understood as two strong magnetic blocks spliced ​​together, or as the two magnetic poles of a strong magnetic block.

[0063] In this embodiment, the back plate 25 of the bracket 2 can be adjusted according to the overall thickness of the strong magnetic blocks before and after splicing.

[0064] In the specification and claims of this utility model, terms indicating direction, such as "front," "rear," "upper," "lower," "left," "right," "side," "top," and "bottom," are used to describe various exemplary structural parts and elements of this utility model. However, the use of these terms is merely for the purpose of explanation and is based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this utility model can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0065] The term "vertical" is also used in the specification and claims of this utility model, meaning basically along the up and down direction, and is not limited to just the vertical direction, but can also be slightly deviated from the vertical direction.
