Description

Technical Field

[0001] This utility model belongs to the field of magnet assembly technology, and in particular relates to a magnet positioning device. Background Technology

[0002] In the field of magnet assembly technology, magnets are assembled onto the circumferential inner wall of the housing. Traditional magnet positioning devices mostly adopt fixed structures or simple mechanical adjustment methods, which make it difficult to achieve precise radial dynamic adjustment. This results in poor fit and weak adaptability between the magnet and the housing, especially when dealing with irregular or non-standard housings, where there are problems with insufficient positioning accuracy and unstable installation. Utility Model Content

[0003] The purpose of this invention is to provide a magnetic positioning device that solves the technical problem of unstable magnetic installation in the prior art.

[0004] To achieve the above objectives, this utility model provides a magnetic positioning device, including a base assembly, a support assembly, and a drive assembly. The base assembly consists of a square base plate and an annular fence frame vertically fixed at its geometric center, forming an axially penetrating operating cavity. The support assembly includes four sets of vertical support columns, which are equidistantly distributed circumferentially within the operating cavity; magnets are fixedly installed on the outer walls of the support columns. The drive assembly includes four sets of movable drive seats, which are arranged diagonally on the outer walls of the square base plate. The drive seats penetrate the annular fence frame and are connected to the corresponding support columns to drive the support columns to move closer to or away from the square base plate along the diagonal direction. A housing for assembling with the magnets is fitted onto the support assembly. When the corresponding drive seats are activated, the four sets of support columns expand outwards, pressing the magnets tightly against the inner walls of the housing.

[0005] Furthermore, there is a gap between the operating cavity and the support column. The support column has a curved outer wall, the curvature of which complements the curvature of the inner wall of the annular fence frame.

[0006] Furthermore, the square base plate has an upwardly extending top column at its center end, and four sets of support columns are arranged around the top column in a circumferential manner; and in the initial state, the support columns are tightly attached to the top column.

[0007] Furthermore, adjustable abutment parts are provided on both sides of the drive seat for abutting against the outer wall of the ring fence frame. The abutment parts are nuts, and threaded holes are provided on both sides of the drive seat, with the nuts inserted into the threaded holes to form a threaded connection.

[0008] Furthermore, the square base plate has diagonal limiting grooves, and fasteners are fixed to these grooves to connect to the main body of the drive unit. A slidable guide rail is located on the upper side of the fastener, and the upper side of the guide rail is fixedly connected to the drive unit. A linear drive module is connected to the side of each drive unit away from the support column, and each linear drive module synchronously drives its corresponding drive unit to move in the corresponding direction.

[0009] The magnetic positioning device provided in this embodiment of the present invention has at least one of the following technical effects:

[0010] This invention utilizes four sets of diagonally synchronized drive seats to coordinate with circumferentially equidistant support columns, which expand radially outwards. This causes the magnets on the outer side of the support columns to form a uniform concentric expansion force on the inner wall of the housing. The symmetry of the diagonal drive ensures the synchronicity and consistency of the magnets' circumferential displacement, avoiding the problems of magnet skewing or localized loose contact caused by traditional unilateral pressure. Furthermore, the dynamic adjustment of the support columns allows the magnet surface to form a full circumferential surface contact with the inner wall of the housing, significantly improving the tightness of the fit. Especially for curved or irregularly shaped housings, the coordinated extension and retraction of the four sets of drive seats can adaptively adjust the contact angle and pressure distribution between the magnets and the inner wall of the housing, eliminating assembly gaps and achieving a stable fit between the magnets and the housing. This enhances the assembly reliability and operational stability of the magnet assembly. Attached Figure Description

The following description is based on the accompanying drawings. Figure 1-4 The described embodiments are exemplary and intended to explain embodiments of the present invention, and should not be construed as limiting the present invention.

They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0025] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0026] In one embodiment of this utility model, a magnetic positioning device is provided, including a base assembly 100, a support assembly 200, and a drive assembly 300. The base assembly 100 consists of a square base plate 110 and an annular fence frame 120 vertically fixed at its geometric center, forming an axially penetrating operating cavity 130. The support assembly 200 includes four sets of vertical support columns 210, which are equidistantly distributed circumferentially within the operating cavity 130; magnets are fixedly installed on the outer walls of the support columns 210. The drive assembly 300 includes four sets of movable drive seats 310, which are arranged diagonally on the outer side wall of the square base plate 110. The drive seats 310 pass through the annular fence frame 120 and are connected to the corresponding support columns 210 to drive the support columns 210 to move closer to or further away from the square base plate 110 along the diagonal direction. The support assembly 200 is fitted with a housing for assembling with the magnet. When the corresponding drive seats 310 are activated, the four sets of support columns 210 expand outward and press the magnet tightly against the inner side wall of the housing.

[0027] Specifically, by having four sets of drive seats 310 moving synchronously along the diagonal, and the support columns 210 distributed circumferentially at equal intervals expanding outward radially, the magnets on the outer side of the support columns 210 form a uniform concentric expansion force on the inner wall of the housing. This utilizes the symmetry of the diagonal drive to ensure the synchronicity and consistency of the circumferential displacement of the magnets, avoiding the problems of magnet skewing or localized loose contact caused by traditional unilateral pressure. Furthermore, the dynamic adjustment of the support columns 210 allows the magnet surface to form a full circumferential surface contact with the inner wall of the housing, significantly improving the tightness of the fit. Especially for curved or irregularly shaped housings, the coordinated extension and retraction of the four sets of drive seats 310 can adaptively adjust the contact angle and pressure distribution between the magnets and the inner wall of the housing, eliminating assembly gaps and achieving a stable fit between the magnets and the housing, thereby enhancing the assembly reliability and operational stability of the magnet assembly.

[0028] Furthermore, a gap exists between the operating cavity 130 and the support column 210. The support column 210 has a curved outer wall, the curvature of which complements the curvature of the inner wall of the annular fence frame 120. The curved surface fit provides guidance for radial movement, preventing the support column 210 from shifting or tilting upon contact, and ensuring uniform contact between the magnet and the inner wall of the housing.

[0029] Furthermore, the square base plate 110 has an upwardly extending top column 400 at its central end, and four sets of support columns 210 are arranged circumferentially around the top column 400; and in the initial state, the support columns 210 are tightly attached to the top column 400. The top column 400 serves as a central reference, ensuring that the four sets of support columns 210 are initially in the same position, maintaining symmetry during expansion, avoiding uneven adhesion caused by asymmetrical displacement of the magnets, and improving assembly accuracy.

[0030] Furthermore, the square base plate 110 has diagonally provided limiting grooves 111, and fasteners 112 are fixed on the limiting grooves 111. The fasteners 112 are used to connect to the body of the drive seat 310. The upper side of the fastener 112 is provided with a slidable guide rail 113, and the upper side of the guide rail 113 is fixedly connected to the drive seat 310. A linear drive module 320 is connected to the side of each drive seat 310 away from the support column 210. The linear drive module 320 synchronously drives the corresponding drive seat 310 to move in the corresponding direction. The drive seat 310 is slidably connected to the fastener 112 through the guide rail 113. When the drive seat 310 moves, it slides along the guide rail 113, and the guide rail 113 restricts its translation only along the diagonal direction.

[0031] Furthermore, both sides of the drive seat 310 are provided with adjustable abutment parts 410 for abutting against the outer wall of the ring fence frame 120. The abutment parts 410 are nuts, and both sides of the drive seat 310 are provided with threaded holes 420, through which the nuts are inserted to form a threaded connection. When a certain guide rail 113 is offset, causing an assembly error, the position of the drive seat 310 can be changed by adjusting the threads, which can be quickly adjusted without additional tools, improving the ease of operation and the adaptability of the device.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
