Description

Technical Field

[0001] The utility model relates to an assembly structure, in particular to a novel assembly structure of a Halbach array magnet. Background Art

[0002] Halbach array is a magnet structure that arranges permanent magnets of different magnetization directions and specifications in a certain order, so that the magnetic field on one side of the array is significantly enhanced.

[0030] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0031] The utility model provides a novel assembly structure of Halbach array magnets to solve the problem in the prior art that since the magnets are connected only by glue, the magnets may fall off during heating and curing, resulting in inability to assemble and excessive flatness of the magnets.

[0032] For ease of understanding, the specific process in the embodiments of the present application is described below. Figures 1 to 4A new type of Halbach array magnet assembly structure in the embodiment of the present application includes a base 1, an embedded seat 2, a storage plate 3, a lateral pressure-maintaining portion 4 and an upper spring pressure head 5; a limiting groove 10 is opened on the upper surface of the base 1; the embedded seat 2 is limited in the limiting groove 10; the storage plate 3 is installed on the upper surface of the embedded seat 2, and a plurality of receiving grooves 30 for accommodating a plurality of linearly distributed magnets 7 are opened on one side of the storage plate 3; the lateral pressure-maintaining portion 4 is arranged on the base 1, and when the embedded seat 2 is limited to the limiting groove 10, one end of the lateral pressure-maintaining portion 4 will laterally maintain pressure and clamp the plurality of magnets 7 located in the accommodating groove 30; the upper spring pressure head 5 is arranged above the storage plate 3, and the plurality of magnets 7 located in the accommodating groove 30 are maintained and pressed in the Z direction through the limiting locking component 6.

[0033] The new Halbach array magnet assembly structure of the utility model places multiple magnets 7 linearly in one end of the accommodating groove 30 for limiting, and then the upper spring pressure head 5 and the lateral pressure holding part 4 are used to hold the magnets 7 in the Z direction and the lateral direction for pressure holding and clamping. In this way, the multiple magnets 7 are pressed together, so that the magnets 7 bonded together only by glue can be heated and cured synchronously, and the automatic assembly of the Halbach magnet is realized by automatic pressure holding throughout the process. The installation is efficient and convenient, and the flatness of the magnets 7 is also effectively guaranteed.

[0034] based on Figure 1 , Figure 3 and Figure 6 In this embodiment, the lateral pressure-maintaining portion 4 includes a positioning block 40, which is installed on the base 1 and is located on the opposite side of the limiting groove 10; a plurality of slots 41 are opened on the lower surface of the positioning block 40, and a transverse pressure-maintaining plate 42 is provided in the slot 41, and one end of the transverse pressure-maintaining plate 42 is connected to the positioning block 40 through a first spring 43, and the other end points to the corresponding receiving groove 30, and the transverse pressure-maintaining plate is used to press the magnet 7 located in the receiving groove 30 forward.

[0035] During operation, when the embedded seat 2 and the storage plate 3 are limited in the limiting groove 10, the position of the embedded seat 2 is fixed relative to the positioning block 40. At this time, a plurality of linearly placed magnets 7 are provided in the accommodating groove 30. Since the magnet 7 is arranged corresponding to one end of the transverse pressure maintaining plate 42, the transverse pressure maintaining plate 42 will be against one end of the plurality of magnets 7, so that the first spring 43 at the other end of the transverse pressure maintaining plate 42 is compressed, thereby realizing the transverse pressure maintaining and clamping of the magnet 7 by the transverse pressure maintaining plate 42, ensuring that the plurality of magnets 7 will not move in the transverse direction.

[0036] Specifically, in this embodiment, the transverse pressure maintaining plate 42 performs lateral pressure maintaining on the side of the magnet. Because the first spring 43 is always in a compressed state during the lateral pressure maintaining, the magnet 7 can be always in a pressed state during the heating and curing process, thereby preventing the repulsive force between the magnets 7 from causing the glue to be unable to bond the magnets, and the assembly is efficient and convenient.

[0037] based on Figure 4 The upper spring pressure head 5 includes an upper pressure plate 50; eight upper pressure columns 51 are arranged through the upper pressure plate 50, and the eight upper pressure columns 51 are grouped in pairs. The upper pressure columns 51 are elastically connected to the clamping block 53 through the second spring. The clamping block 53 is arranged below the upper pressure plate 50, and two upper pressure columns 51 correspond to one clamping block 53. The clamping block 53 is arranged along the direction corresponding to the accommodating groove 30, and covers the upper end of the magnet 7 located in the accommodating groove 30.

[0038] In addition, an adsorption plate 54 for adsorbing the magnet is provided at the bottom of the clamping block 53, so that when multiple magnets 7 are placed on one side of the accommodating groove 30 during installation, the magnets can be first pressed and adsorbed by the adsorption plate 54, thereby facilitating the subsequent clamping block 53 to press the upper plane of the magnet.

[0039] The limit locking component 6 includes a lower socket and an upper limit assembly; the two lower sockets are arranged on both sides of the base 1; the lower socket includes a connecting plate 60 arranged on the embedded seat 2, and the connecting plate 60 is provided with a card plate 61 arranged in a T shape with it, and the top of the card plate 61 has two protrusions 62 extending therefrom; the upper limit assembly is installed on the upper pressure plate 50 and is arranged opposite to the lower socket, and the upper limit assembly includes two upper limit blocks 63 arranged oppositely, and elastic steel balls 64 are arranged in the two upper limit blocks 63, the card plate 61 is arranged between the two elastic steel balls, and two protrusions 62 are arranged on the upper ends of the steel balls.

[0040] During installation, align the upper limit assembly on the entire upper spring pressure head 5 with the lower socket and insert it. At this time, the two protrusions 62 on the top of the card plate 61 are inserted between the two elastic steel balls 64. Since the elastic steel balls 64 are elastic, the elastic steel balls 64 are retracted. When the protrusions 62 exceed the elastic steel balls 64 and are located at the upper ends of the elastic steel balls, the elastic steel balls 64 extend out to press the two sides of the card plate, thereby achieving a fastened connection between the upper spring pressure head 5 and the base 1.

[0041] At this time, since the plurality of upper pressure columns 51 are elastically connected to the pressing block 53 , the second spring is compressed, thereby achieving Z-axis pressure-maintaining and pressing of the pressing block 53 on the magnet 7 .

[0042] Specifically, each clamping block 53 in the upper spring pressure head 5 and the corresponding second spring are designed separately to avoid uneven pressure caused by uneven surface of the magnet 7, and due to the pressure maintenance of the second spring, the pressure can directly act on the product body to achieve good pressure maintenance, and above the magnet, that is, the Z-direction pressure maintenance can always keep the magnet in a pressed state in the Z direction, so that the surface flatness of the magnet reaches no more than 0.05mm.

[0043] Furthermore, the number of the accommodating slots 30 in this embodiment is four, and the four accommodating slots 30 are arranged in parallel. Of course, the number can be set according to actual needs.

[0044] Furthermore, a bayonet 31 is provided at one end of the receiving groove for facilitating taking out the magnet 7 , so that after the magnet is heated and solidified, the assembled magnet can be conveniently taken out through the bayonet 31 .

[0045] Furthermore, an anti-mistake corner 20 is provided on the embedded seat 2 to prevent the magnet from being installed upside down. The anti-mistake corner 20 can distinguish the positive and negative poles of the magnet 7, so that the magnet assembly has an anti-mistake effect and avoids the magnet being installed with the wrong polarity, causing the customer to be unable to use it.

[0046] based on Figures 1 to 6 , the actual working process is as follows:

[0047] First, three magnets 7 are placed in the receiving groove 30 , and then glue is dispensed between the magnets 7 so that the three magnets are adsorbed together, and the adsorption plate 54 is installed on the upper surfaces of the three magnets so that the magnets adsorb the adsorption plate 54 .

[0048] Then, the lower socket is fixedly connected to the upper limit assembly, so that the upper spring pressure head 5 is fixed on the embedded seat 2, so that the clamping block 53 can press the three magnets in the Z direction through the adsorption plate 54 to maintain pressure.

[0049] The installed embedded seat 2 is fixed in the base 1 as a whole through the limiting groove 10. After the installation is completed, due to the action of the first spring 43, the lateral pressure-maintaining plate 42 corresponding to the accommodating groove 30 performs lateral pressure-maintaining and tightening on the three magnets.

[0050] Finally, after assembling the magnets, the assembly structure can be placed in a curing furnace for heating and curing, thereby automatically completing the assembly of the Hybel array magnet.

[0051] The new Halbach array magnet assembly structure of the utility model is easy to assemble and simple to operate. It can effectively and quickly assemble the Halbach array magnet, maintain the pressure of the magnet in the Z direction and the lateral direction throughout the whole process, has high processing efficiency, and has good flatness of the magnet.

[0052] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
