Description

Technical Field

[0001] This application relates to the field of magnetic track technology, and more particularly to a mover assembly and a magnetic track. Background Technology

[0002] In the design of existing linear motor module mover assemblies, the conventional approach is to integrate the slider assembly and the slide table into a single unit. While this integrated structure contributes to overall compactness, it also presents challenges in achieving the performance of key moving components. Specifically, the roller assembly in the slider unit typically employs a multi-row ball bearing layout. When applying preload, it is necessary to ensure that the preload force of each row of balls is uniform and consistent. However, due to the complex structural constraints and interactions, the difficulty of preload control during actual adjustment is significantly increased. Furthermore, to ensure smooth motion and rigidity, the relative positional accuracy requirements of the multi-row ball bearing guide groove profiles are extremely stringent. Utility Model Content

[0003] In view of this, the purpose of this application is to overcome the shortcomings of the prior art and provide a mover assembly and magnetic rail to alleviate the problems of difficult preload adjustment of the mover assembly and high requirements for the machining accuracy of the guide rail in the prior art.

[0004] This application provides the following technical solution: In a first aspect, embodiments of this application provide a moving part assembly for a magnetic track, the moving part assembly comprising: A slide assembly, the slide assembly including a first positioning end face and a plurality of positioning parts, wherein each of the positioning parts is spaced apart on the first positioning end face; At least one slider assembly, each slider assembly being detachably disposed on the slider assembly, the slider assembly including at least one roller assembly, a first positioning mating end face and a plurality of positioning holes, the first positioning mating end face and the first positioning end face being parallel and abutting each other, the positioning holes being spaced apart on the first positioning end face, each positioning hole being respectively disposed corresponding to each positioning part, so that each positioning hole is provided with a corresponding positioning part and a positioning fit is formed.

[0005] In some embodiments of the first aspect, the slide assembly further includes a sliding table plate and a linear motor mover, the first positioning end face is disposed on the sliding table plate, the first positioning end face forms a receiving groove, the linear motor mover is received in the receiving groove, the linear motor mover abuts against each of the groove side walls and the groove bottom wall of the receiving groove respectively, and an adhesive injection channel is formed between the linear motor mover and each of the groove side walls and / or the groove bottom wall.

[0006] In some embodiments of the first aspect, at least a portion of the dispensing channel extends along the length of the moving part assembly.

[0007] In some embodiments of the first aspect, the inner wall of the receiving groove has a guide groove, one end of which is connected to one of the glue injection channels, and the other end extends to the portion of the groove sidewall that abuts against the linear motor mover.

[0008] In some embodiments of the first aspect, the glue injection channel is formed between the corner of the receiving groove and the linear motor mover.

[0009] In some embodiments of the first aspect, the sliding plate has a plurality of through holes, each of the through holes corresponding to a respective positioning hole, the positioning part has a limiting end and a threaded end, the threaded end passes through the through hole and is threadedly connected to the hole wall of the positioning hole, and the limiting end and the end of the sliding plate opposite to the sliding assembly abut against the limiting end.

[0010] In some embodiments of the first aspect, the positioning part and the positioning hole are tapered.

[0011] In some embodiments of the first aspect, the slide assembly includes a second positioning end face, the slider assembly includes a second positioning mating end face, the second positioning end face and the second positioning mating end face are parallel and abut against each other, and the plane where the second positioning end face is located intersects with the plane where the first positioning end face is located.

[0012] In some embodiments of the first aspect, the slider assembly further includes a slider, the roller assembly and the slider are detachably connected, the slider has a positioning groove, the roller assembly is at least partially located in the positioning groove, and forms a positioning engagement.

[0013] Secondly, embodiments of this application also provide a magnetic track, the magnetic track including a mover assembly as described in any of the above embodiments.

[0014] The embodiments of this application have the following advantages: This application provides a mover assembly. The slide assembly is mainly responsible for mounting and bearing external loads, and its core function is to provide a robust mounting reference and bearing surface. The slider assembly is an independent functional unit, integrating multiple rows of roller assemblies, specifically responsible for achieving high-precision linear motion on the magnetic track. When the slider assembly needs to be mounted onto the slide assembly, the first positioning mating end face of the slider assembly abuts parallel to the first positioning end face of the slide assembly. This first establishes the reference of the two components in the vertical direction (or normal direction), ensuring the flatness and coplanarity of the installation. Multiple positioning parts (which can be understood as positioning pins or bosses) on the slide assembly are precisely inserted into the corresponding positioning holes on the slider assembly. This positioning method completely restricts the degrees of freedom of the two components in all directions in the horizontal plane, ensuring the precise and repeatable installation position of the slider assembly relative to the slide assembly. After precise positioning is achieved through the positioning end face and positioning parts, the two components are locked and fixed using fasteners such as screws (which may be mentioned in the full text of the patent), thereby forming a complete, high-rigidity mover assembly.

[0015] Therefore, this application significantly reduces the difficulty and complexity of preload adjustment. Since the slider assembly is an independent module, the preload of its internal roller assembly can be finely adjusted individually on a dedicated tooling or platform before assembly with the slide table assembly. This avoids the difficulty of simultaneously coordinating the slide table load and the preload of multiple rows of steel balls in a space-constrained overall machine configuration. Independent adjustment allows operators to focus more on the performance of the slider assembly itself, ensuring uniform preload force across each row of steel balls, thus making it easier to achieve optimal motion smoothness and rigidity. Furthermore, it significantly reduces the machining accuracy requirements of the guide rail (rail). Traditional integrated designs require extremely high relative positional accuracy between the slide table mounting surface and the guide rail raceways. In this design, the slide table assembly and guide rail no longer have a direct and stringent relationship. The slider assembly itself guarantees the relationship between the rollers and the mounting surface. As long as the slider assembly is precisely positioned on the slide table, motion accuracy can be transferred. This allows for a more relaxed machining tolerance requirement for the raceways of long-length magnetic rails, reducing manufacturing costs. Furthermore, when the rollers in the slider assembly need to be replaced due to wear and tear from long-term use, it is not necessary to replace the entire expensive mover; only the individual slider module needs to be disassembled and replaced, greatly reducing maintenance costs and time. Slider assemblies of the same specification can be flexibly matched with slide table assemblies of different shapes and sizes to adapt to different loads and application scenarios, improving design flexibility.

[0025] In related technologies, the conventional approach in the design of the mover assembly of existing linear motor modules is to integrate the slider assembly and the slide table. While this integrated structure contributes to overall compactness, it also presents challenges to achieving the performance of key moving components. Specifically, the roller assembly in the slider unit typically employs a multi-row ball bearing layout. When applying preload, it is necessary to ensure that the preload force of each row of balls is uniform and consistent. However, due to the complexity of structural constraints and interactions, the difficulty of preload control during actual adjustment is significantly increased. Furthermore, to ensure smooth motion and rigidity, the relative positional accuracy requirements of the multi-row ball bearing guide groove contours are extremely stringent.

[0026] As shown in Figure 1, Figure 2 and Figure 3 As shown, in order to solve the above-mentioned technical problems, this application provides a moving part assembly 100 for a magnetic track 10. The moving part assembly 100 includes a slide assembly and at least one slider 120 assembly. The slide assembly includes a first positioning end face 111 and a plurality of positioning parts, and the positioning parts are distributed at intervals on the first positioning end face 111.

[0027] Each slider 120 assembly is detachably mounted on the slider 120 assembly. The slider 120 assembly includes at least one roller assembly 140, a first positioning mating end face 121, and a plurality of positioning holes 123. The first positioning mating end face 121 and the first positioning end face 111 are parallel and abut against each other. The positioning holes 123 are spaced apart on the first positioning end face 111. Each positioning hole 123 is respectively provided with a corresponding positioning part, so that a corresponding positioning part passes through each positioning hole 123 and forms a positioning fit.

[0028] In these embodiments, a mover assembly 100 for a linear motor module is provided, which includes a slide assembly and at least one slider assembly 120. The slide assembly and slider assembly 120 adopt a detachable, separate structure design, effectively solving the problems of difficult preload adjustment and excessively high guide rail machining precision requirements in traditional integrated structures.

[0029] The slide assembly has a plate-like or frame-like structure, and a first positioning end face 111 is provided on the side facing the stator assembly. Multiple positioning portions are distributed at intervals on the first positioning end face 111. In this embodiment, the positioning portions are four cylindrical bosses extending perpendicular to the first positioning end face 111, arranged in a rectangular array at the four corners of the first positioning end face 111.

[0030] The slider 120 assembly includes a housing, at least one roller assembly 140, a first positioning mating end face 121, and a plurality of positioning holes 123. The roller assembly 140 may be a multi-row circulating ball structure, such as a two-row or four-row steel ball layout, installed in a guide groove inside the housing for achieving low-friction linear motion on the magnetic track 10.

[0031] The first positioning mating end face 121 is located at the bottom of the slider 120 assembly (i.e., the side closest to the slide assembly) and is parallel to and in close contact with the first positioning end face 111 of the slide assembly. Multiple positioning holes 123 are provided on the first positioning mating end face 121, corresponding to the positioning part of the slide assembly. The positioning holes 123 are through holes, with an inner diameter slightly larger than the outer diameter of the positioning part, allowing the positioning part to be smoothly inserted into the positioning holes 123, forming a high-precision positioning mating pair.

[0032] During assembly, the slider 120 assembly is first placed above the slide assembly, so that the first positioning mating end face 121 is in contact with the first positioning end face 111. Then, the positioning parts on the slide assembly are respectively inserted into the corresponding positioning holes 123 of the slider 120 assembly. Due to the precise fit between the positioning parts and the positioning holes 123, the position of the slider 120 assembly in the X and Y directions in the horizontal plane is precisely defined, and its attitude relative to the slide assembly is also constrained, avoiding uneven ball preload caused by assembly errors.

[0033] More importantly, since the slider 120 assembly and the slide table assembly are detachably connected (they can be further fixed by screws, clips, etc., but do not necessarily rely on welding or integral molding), each slider 120 assembly can be pre-pressed and adjusted individually.

[0034] Furthermore, since the slider 120 assembly itself has a complete raceway structure and positioning reference, the relative positional accuracy requirement between the guide grooves of the magnetic track 10 no longer depends on the overall machining accuracy of the slide assembly, thereby relaxing the overall machine manufacturing tolerance and reducing costs.

[0035] In another embodiment, the positioning part can be designed as a tapered pin, a keyway structure, or a threaded positioning post. Correspondingly, the positioning hole 123 can be a tapered hole, a keyway hole, or a threaded hole to adapt to different assembly requirements. The number of positioning parts can also be adjusted to two, three, or more according to the size of the slider 120 and the load requirements, as long as it can achieve effective constraint of six degrees of freedom in the plane.

[0036] In the mover assembly 100 containing multiple slider 120 components (such as a dual slider 120 or quad slider 120 layout), each slider 120 component can be installed and adjusted independently without rigid coupling between them, further improving the maintainability and modularity of the system.

[0037] As can be seen from the above specific implementation, by designing the slide table assembly and the slider 120 assembly separately and introducing a positioning part and positioning hole 123 matching structure, not only is high-precision assembly positioning achieved, but the ball preload can also be adjusted independently, effectively alleviating the problems of difficult preload adjustment and excessively high requirements for guide rail machining accuracy in the prior art.

[0038] In some embodiments, the slide assembly further includes a sliding plate 110 and a linear motor mover 130. A first positioning end face 111 is disposed on the sliding plate 110, and a receiving groove 114 is formed on the first positioning end face 111. The linear motor mover 130 is received in the receiving groove 114. The linear motor mover 130 abuts against each side wall and bottom wall of the receiving groove 114, and an adhesive injection channel 115 is formed between the linear motor mover 130 and each side wall and / or bottom wall of the groove.

[0039] In these embodiments, the first positioning end face 111 is disposed on the lower surface (or upper surface, depending on the installation direction) of the sliding platform 110 for docking with the first positioning mating end face 121 of the slider 120 assembly.

[0040] A receiving groove 114 is formed in the central region of the first positioning end face 111. The receiving groove 114 is surrounded by a bottom wall and multiple side walls, and has an overall rectangular or U-shaped cavity structure. The linear motor mover 130 is precisely fitted into the receiving groove 114, and its outer contour matches the receiving groove 114. Specifically, the outer peripheral side of the linear motor mover 130 is in close contact with each side wall of the groove, and its bottom surface is in contact with the bottom wall of the groove, thereby achieving good mechanical positioning and heat conduction path.

[0041] Crucially, a small gap is provided between the linear motor mover 130 and at least one side wall and / or bottom wall of the receiving groove 114, which forms the glue injection channel 115. For example, in this embodiment, the gap left between the non-contacting parts of the linear motor mover 130 and the side wall or bottom wall of the receiving groove 114 forms the glue injection channel 115.

[0042] The colloid is evenly filled into the space between the linear motor mover 130, the side wall of the groove, and the bottom wall of the groove through the glue injection channel 115. After curing, it not only plays a fixing role to prevent the mover from loosening during high-speed movement, but also provides an efficient heat conduction path to quickly conduct the heat generated by the linear motor mover 130 during operation to the sliding platform 110, and then dissipate it into the environment, effectively improving the thermal stability and long-term operational reliability of the system.

[0043] In other variant embodiments, the glue injection channel 115 may be provided only between one side of the groove wall and the mover, or only at the bottom; the gap size may also be actively controlled by machining micro-protrusions on the outer surface of the mover or by setting limiting ribs on the groove wall to ensure that the glue injection amount is controllable and evenly distributed.

[0044] Through the above structural design, not only is the modular and high-precision assembly of the slider 120 component and the slide table realized, but also the integrated solution of the receiving groove 114 and the glue injection channel 115 takes into account the three major requirements of precise positioning, reliable fixation and efficient heat dissipation of the linear motor mover 130, which significantly improves the overall performance and manufacturing yield of the linear motor module.

[0045] In some embodiments, at least a portion of the dispensing channel 115 extends along the length of the mover assembly 100.

[0046] In these embodiments, at least a portion of the injection channel 115 extends along the length of the mover assembly 100 (i.e., the direction of movement of the linear motor module). Specifically, when the linear motor mover 130 is installed in the receiving groove 114, the gap between it and one or both sides of the groove sidewall is not limited to a local area, but extends continuously along the entire effective magnetic pole length, thereby forming a longitudinally extending injection channel 115.

[0047] For example, in this embodiment, the width of the linear motor mover 130 is slightly smaller than the inner width of a portion of the receiving groove 114, and this dimensional difference remains consistent throughout the entire length direction, resulting in two narrow gaps parallel to the length direction between the mover and the left and right sidewalls of the groove. These two gaps constitute the glue injection channel 115 extending along the length direction. Alternatively, a central glue injection channel 115 extending along the length direction can be provided between the bottom of the mover and the bottom wall of the groove, or the glue flow can be guided by creating an axial groove on the bottom surface.

[0048] This length-extending adhesive channel 115 allows the adhesive to be injected from one end or the middle, flowing naturally along the entire length of the mover, avoiding local voids or air bubbles and ensuring consistent bonding and thermal conductivity. The cured adhesive layer is continuously distributed along the direction of movement, effectively resisting shear stress caused by high-speed start-stop or vibration, preventing axial displacement of the mover. The continuous thermally conductive adhesive layer along its length can more evenly conduct heat generated in each segment of the mover to the sliding platform 110, avoiding localized hotspot accumulation and improving thermal management efficiency.

[0049] In other variant embodiments, a glue injection channel 115 extending along the length direction may be provided only on one side, while the other side is fixed by interference fit or dispensing; or a glue injection inlet may be provided at the end of the mover, with the middle connected by a microgroove to achieve controllable filling.

[0050] In some embodiments, the inner wall of the receiving groove 114 has a flow guide groove, one end of which is connected to one of the glue injection channels 115, and the other end extends to the part of the groove sidewall that abuts against the linear motor mover 130.

[0051] To further improve the controllability and filling integrity of the adhesive, in some embodiments, at least one flow guide groove is provided on the inner wall of the receiving groove 114. The flow guide groove can be machined on the surface of the side wall or bottom wall of the groove, and has a recessed channel structure.

[0052] Specifically, one end of the guide groove is connected to the aforementioned glue injection channel 115 (e.g., a lateral glue injection channel 115 extending along the length direction), serving as the glue inflow path. It is close to the linear motor rotor and the groove wall extrusion part. The glue flows into the glue injection channel 115 along the guide groove, avoiding accumulation between the linear motor rotor and the groove wall, which is conducive to the installation of the linear motor mover 130.

[0053] Furthermore, the flow channel can be connected to multiple glue injection channels 115 to form a mesh flow guidance system. For example, in a long-stroke mover, a main glue injection port can be set in the middle, and the flow channels on both sides can be used to guide the glue to the two end contact areas to achieve bidirectional filling, significantly reducing air bubble residue and filling blind areas.

[0054] In some embodiments, the glue injection channel 115 is formed between the corner of the receiving groove 114 and the linear motor mover 130.

[0055] In some embodiments, a local gap is naturally formed between the corner area of ​​the receiving groove 114 (i.e., the intersection of two adjacent groove sidewalls, or the inner angle formed by the intersection of the groove sidewall and the groove bottom wall) and the corresponding outer angle of the linear motor mover 130, and this gap constitutes an additional glue injection channel 115.

[0056] Specifically, since the linear motor mover 130 is usually a rectangular or chamfered prism structure, and the inner cavity of the receiving groove 114 also has a corresponding shape, in actual processing, to avoid stress concentration or facilitate demolding, the inner corners of the receiving groove 114 are often designed as small rounded corners, while the outer corners of the linear motor mover 130 may be right angles or smaller chamfers. This geometric difference results in the inability to achieve complete fit at the corners, thus forming small but connected gaps at the four inner corner positions (or some corner positions), namely the corner glue injection channels 115.

[0057] During the adhesive injection process, the adhesive can flow along the main injection channel 115 and diffuse into corner areas through the corner injection channels 115, effectively filling the inner corner areas that are prone to dead zones in traditional processes, reducing air bubbles and voids. Corners are potential pathways for contaminants and moisture to enter; filling the corner channels with adhesive can achieve full circumferential sealing and improve environmental adaptability. Under conditions of thermal expansion and contraction or vibration, stress concentration is prone to occur in corner areas; after filling with adhesive, it can act as a buffer, preventing the mover or sliding platform 110 from cracking or deforming at the corners.

[0058] In some embodiments, the sliding plate 110 has a plurality of through holes 113, each through hole 113 corresponding to each of the positioning holes 123. The positioning part has a limiting end and a threaded end. The threaded end passes through the through hole 113 and is threadedly connected to the hole wall of the positioning hole 123. The limiting end and the end of the sliding plate 110 away from the sliding assembly abut against each other for limiting.

[0059] In these embodiments, the sliding platform 110 has multiple through holes 113, and the position of each through hole 113 corresponds one-to-one with the positioning hole 123 on the slider 120 assembly. Accordingly, the positioning part is not a simple cylindrical boss, but is designed as a stepped positioning bolt structure with a limit end and a threaded end.

[0060] The specific assembly process is as follows: The slider 120 assembly is placed below the sliding platform 110, with its first positioning mating end face 121 initially aligned with the first positioning end face 111 of the sliding platform 110. From above the sliding platform 110 (i.e., the side opposite to the slider 120 assembly), the threaded end of the positioning part is sequentially passed through the corresponding through holes 113. The threaded end continues to be screwed downwards into the positioning hole 123 on the slider 120 assembly, where the inner wall of the positioning hole 123 has an internal thread matching the threaded end, forming a threaded connection pair. As the thread is tightened, the limiting end of the positioning part (usually a head or flange structure) finally abuts tightly against the upper surface of the sliding platform 110 (i.e., the end face opposite to the mounting side of the sliding platform assembly), achieving axial limiting.

[0061] The positioning section simultaneously performs the functions of precise positioning (through the coaxiality and clearance control of the threaded pair) and mechanical fastening (through the threaded locking force). Due to the self-centering characteristic of the threaded connection itself, and in conjunction with the coaxiality control of the through hole 113 and the positioning hole 123, it can be ensured that the position height of the slider 120 assembly relative to the sliding platform 110 is consistent after each disassembly and assembly, which is conducive to modular maintenance and replacement.

[0062] In this embodiment, the through hole 113 is a smooth hole with a diameter slightly larger than the major diameter of the threaded end to avoid interference; the limiting end is a hexagonal head or countersunk head structure for easy operation with a wrench or Allen wrench. The thread depth of the positioning hole 123 is designed according to the thickness of the slider 120 housing to ensure sufficient engagement length.

[0063] In some embodiments, the positioning part and the positioning hole 123 are taper-fitted.

[0064] In these embodiments, a tapered fit structure is adopted between the positioning part and the positioning hole 123 to further improve the positioning accuracy and eliminate the fit gap.

[0065] Specifically, the outer peripheral surface of the positioning part (which can be the entire rod or a partial section) is designed as an outer conical surface, with a taper preferably between 1:50 and 1:100 (e.g., Morse taper or a custom small taper), while the inner wall of the corresponding positioning hole 123 is machined into a matching inner conical surface. When the positioning part is inserted into the positioning hole 123, the axial force generated by axial pressing or thread tightening causes the inner and outer conical surfaces to fit tightly together, forming a gapless interference or transition fit.

[0066] In a preferred embodiment, the positioning part retains the aforementioned limiting end and threaded end structure, but the threaded end has a tapered guide section (i.e., an outer tapered surface) near the head, while the upper part of the positioning hole 123 has a corresponding inner tapered surface. When the threaded end is screwed into the positioning hole 123, the tapered guide section first contacts the inner tapered surface and automatically centers. Subsequently, as the thread continues to tighten, the axial force causes the tapered surface to fully fit, achieving self-centering, zero-backlash precision positioning.

[0067] In some embodiments, the slide assembly includes a second positioning end face 112, and the slider 120 assembly includes a second positioning mating end face 122. The second positioning end face 112 and the second positioning mating end face 122 are parallel and abut against each other. The plane where the second positioning end face 112 is located intersects with the plane where the first positioning end face 111 is located.

[0068] In these embodiments, the slide assembly not only has the aforementioned first positioning end face 111, but also a second positioning end face 112. Correspondingly, the slider 120 assembly, in addition to having the first positioning mating end face 121, also has a second positioning mating end face 122.

[0069] The first positioning end face 111 and the first positioning mating end face 121 are parallel to each other and are mainly used to constrain the position of the slider 120 assembly in the Z direction (perpendicular to the motion plane) and restrict the rotation around the X and Y axes; while the second positioning end face 112 and the second positioning mating end face 122 are also parallel to each other and are used to constrain the translational degree of freedom of the slider 120 assembly in the Y direction (or X direction, depending on the layout) and the rotational degree of freedom around the Z axis.

[0070] The plane containing the second positioning end face 112 intersects with the plane containing the first positioning end face 111. In a preferred embodiment, the two are perpendicular to each other, forming an L-shaped or right-angled combination of positioning reference surfaces. For example: The first positioning end face 111 is the bottom surface (XY plane) of the sliding table 110. The second positioning end face 112 is its side elevation (YZ plane).

[0071] The housing of the slider 120 assembly has a corresponding bottom surface (first positioning and mating end surface 121) and a side surface (second positioning and mating end surface 122).

[0072] During assembly, the slider 120 assembly is pushed in from below at an angle, so that its first positioning mating end face 121 fits against the first positioning end face 111, while its second positioning mating end face 122 fits against the second positioning end face 112. Then, the aforementioned positioning part (such as a tapered threaded positioning pin) passes through the through hole 113 and is screwed into the positioning hole 123 to achieve final locking.

[0073] In some embodiments, the slider 120 assembly further includes a slider 120, the roller assembly 140 and the slider 120 are detachably connected, the slider 120 has a positioning groove, and the roller assembly 140 is at least partially located in the positioning groove and forms a positioning fit.

[0074] In these embodiments, the slider 120 assembly further includes a slider 120 body and a roller assembly 140, which are assembled in a detachable connection manner.

[0075] Specifically, a positioning groove is provided inside the slider 120 body. This positioning groove is typically a U-shaped or rectangular cavity extending along the length of the slider 120 (i.e., the direction of movement of the mover assembly 100), and its contour matches the shape of the roller assembly 140. The roller assembly 140 (e.g., a complete unit including a cage, multiple rows of circulating steel balls, and end caps) is integrally fitted into the positioning groove, with at least part of the structure (such as the outer ring or mounting flange) completely accommodated in the groove, forming a precise positioning fit with the groove wall (including the side walls and bottom wall).

[0076] In one implementation, the outer periphery of the roller assembly 140 is provided with a positioning flange, and the corresponding position of the positioning groove is provided with a step or a limiting shoulder. After the two abut against each other, the displacement of the roller assembly 140 in the Z direction is restricted. At the same time, the width of the positioning groove and the width of the roller assembly 140 are fitted with a small clearance to ensure positioning accuracy in the X direction. In addition, the roller assembly 140 can be fixed to the slider 120 body by at least one fastener (such as a countersunk screw or a spring clip) to achieve a detachable connection.

[0077] like Figure 4 As shown, in some embodiments, this application also provides a magnetic track 10, which includes any of the moving parts 100 described in the above embodiments.

[0078] Since the aforementioned mover assembly 100 has the above-mentioned technical effects, the magnetic track 10 including the mover assembly 100 should have the same technical effects, which will not be described in detail here.

[0079] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limitations; therefore, other examples of exemplary embodiments may have different values.
