[0024] The present utility model will be further described below in conjunction with the accompanying drawings and specific implementation modes.

[0025] This embodiment provides a continuous pressure maintaining device for a Halbach magnetic component 6, as Figures 1 to 7 shown, which includes a bottom plate 1, a first pusher device 2, a second pusher device 3, a locking device 4, and a jig 5 for placing the Halbach magnetic component 6; the first pusher device 2 is slidably arranged on one side of the bottom plate 1, the second pusher device 3 is slidably arranged on the other side of the bottom plate 1, the first pusher device 2 and the second pusher device 3 are respectively provided with a locking device 4, the jig 5 is placed between the first pusher device 2 and the second pusher device 3, and the first pusher device 2 and the second pusher device 3 are used to respectively slide and push against both ends of the Halbach magnetic component 6 abutted against the jig 5, and the locking device 4 is used for limiting to realize the continuous pressure maintaining of the Halbach magnetic component 6.

[0026] In this embodiment, through the first pusher device 2 and the second pusher device 3, the pushing against both ends of the Halbach magnetic component 6 can be accurately and quickly realized. Since the first pusher device 2 and the second pusher device 3 are respectively provided with a locking device 4, when the first pusher device 2 and the second pusher device 3 respectively slide and push against both ends of the Halbach magnetic component 6 abutted against the jig 5, the locking device 4 can be used for limiting to realize the continuous pressure maintaining of the Halbach magnetic component 6, ensuring that the Halbach magnetic component 6 can maintain a stable shape and position during the subsequent glue curing process and guaranteeing the product quality. The first pusher device 2 and the second pusher device 3 in this embodiment are slidably arranged, so they can be pushed by the operator's both hands or additionally pushed by automated equipment. The structure is simple, and because of the small volume, the whole device can be placed in equipment such as an oven to accelerate the glue curing and improve the production efficiency.

[0027] As Figure 2As shown in the figure, the first material pushing device 2 of this embodiment includes a first fixing block 21, a first push plate 22, a limiting strip 23 and a first return spring 24. The first fixing block 21 is horizontally slidably arranged on the left side of the bottom plate 1. The first push plate 22 is fixedly arranged on the first fixing block 21. A plurality of first push rods 221 are arranged on the side of the first push plate 22 close to the jig 5. The first push rods 221 of the first push plate 22 are driven by the horizontal sliding of the first fixing block 21 to abut against one end of the Halbach magnetic assembly 6 on the jig 5, so as to realize the pressure holding of one end of the Halbach magnetic assembly 6. Since the jig 5 is placed between the first material pushing device 2 and the second material pushing device 3, a first push plate 22 is provided in this embodiment. Six first push rods 221 are arranged on the right side of the first push plate 22, but not limited to this. Each first push rod 221 corresponds to a group of Halbach magnetic assemblies 6 on the jig 5. A limiting strip 23 is longitudinally arranged between the first fixing block 21 and the jig 5, and the first return spring 24 is arranged between the first fixing plate and the limiting strip 23. The first return spring 24 is arranged at both the front and rear ends of the first fixing block 21 in this embodiment. The function of the first return spring 24 is to ensure the automatic reset of the first push rod 221. When the first fixing block 21 slides horizontally to drive the first push rods 221 of the first push plate 22 to abut against one end of the Halbach magnetic assembly 6 on the jig 5 and is limited by the locking device 4 to realize continuous pressure holding, the two first return springs 24 are compressed. When the locking device 4 is unlocked, the elastic force of the two first return springs 24 can push the first fixing block 21 together with the first push rods 221 back to the original position, without the need for the operator to manually slide the first fixing block 21, which is convenient to operate and simple to use.

[0028] As Figure 2 shown, it further includes a first slide rail 25 and a first slider 26. The first slide rail 25 is horizontally fixedly arranged on the left side of the bottom plate 1. The first slider 26 is horizontally slidably arranged on the first slide rail 25. The first fixing block 21 is fixedly arranged on the first slider 26. The first fixing block 21 horizontally slides on the bottom plate 1 along the first slide rail 25 through the first slider 26. The first slide rail 25 of this embodiment provides a stable sliding track for the first slider 26, ensuring that the first fixing block 21, the first push plate 22 and the first push rods 221 thereon can slide along a predetermined straight line direction, reducing the deviation and jitter during the sliding process, so that the first push rods 221 can more accurately abut against the Halbach magnetic assembly 6. And the sliding mechanism of the first slider 26 cooperating with the first slide rail 25 is simple and clear, and the operator can easily operate it.

[0029] As Figure 1 、 Figure 2 、 Figure 4 and Figure 5As shown, the locking device 4 in this embodiment is a plunger 41. One end of the plunger 41 is provided with a spring pin 42, and the other end of the plunger 41 is provided with a pull ring 43. The pull ring 43 is used to control the telescopic movement of the spring pin 42. When the pull ring 43 is lifted upward, the spring pin 42 retracts into the interior of the plunger 41. A first through hole 211 is formed in the first fixing block 21, and a first limiting blind hole 11 is formed in the bottom plate 1 at a position matching the first through hole 211. The plunger 41 passes through the first through hole 211. When the first fixing block 21 drives the first push rod 221 of the first push plate 22 to abut against one end of the Halbach magnetic assembly 6 on the jig 5, limiting is performed to achieve continuous pressure maintenance. After the glue of the Halbach magnetic assembly 6 is cured, only by lifting the pull ring 43 upward, the spring pin 42 retracts into the interior of the plunger 41, and the elastic force of the two first return springs 24 can push the first fixing block 21 together with the first push rod 221 back to the original position, with a clever design. In this embodiment, a plunger 41 is arranged in the middle of the first fixing block 21 for limiting. In other embodiments, the arrangement position and number of the plungers 41 can also be adjusted according to actual needs.

[0030] As Figure 3As shown, the second pushing device 3 includes a second fixing block 31, a second pushing plate 32, a limiting block 33, a buffer spring 34 and a second return spring 35. The second fixing block 31 is horizontally slidably arranged on the right side of the bottom plate 1. Different from the first pushing device 2, in this embodiment, the second pushing plate 32 is horizontally slidably arranged on the second fixing block 31. On the side of the second pushing plate 32 close to the fixture 5, there are several second push rods 321. The buffer spring 34 is arranged between the side of the second pushing plate 32 away from the fixture 5 and the second fixing block 31. The second fixing block 31 drives the second push rods 321 of the second pushing plate 32 to abut against the other end of the Halbach magnetic assembly 6 on the fixture 5, so as to realize the pressure holding of the other end of the Halbach magnetic assembly 6. The buffer spring 34 can ensure that the second push rod 321 and the magnet at the other end of the Halbach magnetic assembly 6 are fully squeezed in place, avoiding the influence of tolerance on the pressure holding effect of the Halbach magnetic assembly 6. Since the fixture 5 is placed between the first pushing device 2 and the second pushing device 3, three second pushing plates 32 are provided in this embodiment. On the left side of each second pushing plate 32, two second push rods 321 are provided, but not limited to this. Each second push rod 321 corresponds to a group of Halbach magnetic assemblies 6 on the fixture 5. And the bottom plate 1 is respectively provided with limiting blocks 33 at both ends of the fixture 5, and the second return spring 35 is arranged between the second fixing plate and the limiting block 33. In this embodiment, the second return spring 35 is provided at both the front and rear ends of the fixture 5. The function of the second return spring 35 is to ensure the automatic reset of the second push rod 321. When the second fixing block 31 slides horizontally to drive the second push rods 321 of the second pushing plate 32 to abut against the other end of the Halbach magnetic assembly 6 on the fixture 5 and is limited by the locking device 4 to realize continuous pressure holding, the two second return springs 35 are compressed. When the locking device 4 is unlocked, the elastic force of the two second return springs 35 can push the second fixing block 31 together with the second push rods 321 back to the original position, without the need for an operator to manually slide the second fixing block 31, which is convenient to operate and simple to use.

[0031] As Figure 3As shown, this embodiment further includes a second slide rail 311, a second slider 312, a third slide rail 36 and a third slider 37. The second slide rail 311 is horizontally and fixedly arranged on the second fixed block 31. The second push plate 32 is fixedly arranged on the second slider 312. The second push plate 32 slides horizontally on the second fixed block 31 along the second slide rail 311 through the second slider 312. Since the buffer spring 34 is arranged between the side of the second push plate 32 away from the jig 5 and the second fixed block 31, the second push plate 32, in cooperation with the second slide rail 311 and the second slider 312, can ensure that the second push rod 321 fully presses against the magnet at the other end of the Halbach magnetic assembly 6. The third slide rail 36 is horizontally and fixedly arranged on the right side of the bottom plate 1. The third slider 37 is horizontally slidably arranged on the third slide rail 36. The second fixed block 31 is fixedly arranged on the third slider 37. The second fixed block 31 slides horizontally on the bottom plate 1 along the third slide rail 36 through the third slide. The third slide rail 36 of this embodiment provides a stable sliding track for the third slider 37, ensuring that the second fixed block 31, the second push plate 32 and the second push rod 321 thereon can slide along a predetermined straight line direction, reducing the deviation and jitter during the sliding process, so that the second push rod 321 can more accurately abut against the Halbach magnetic assembly 6.

[0032] As Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the locking device 4 is a plunger 41. One end of the plunger 41 is provided with a spring pin 42, and the other end of the plunger 41 is provided with a pull ring 43. The pull ring 43 is used to control the expansion and contraction of the spring pin 42. A second through hole 313 is opened on the second fixed block 31. A second limit blind hole 12 is opened on the bottom plate 1 at a position matching the second through hole 313. The plunger 41 passes through the second through hole 313. When the second push rod 321 of the second fixed block 31 driving the second push plate 32 abuts against the other end of the Halbach magnetic assembly 6 on the jig 5, the spring pin 42 at one end of the plunger 41 is embedded in the second limit blind hole 12 for limiting to achieve continuous pressure holding. After the glue of the Halbach magnetic assembly 6 is cured, only need to lift the pull ring 43 upward, the spring pin 42 retracts into the plunger 41, and the elastic force of the two second return springs 35 can push the second fixed block 31 together with the second push rod 321 back to the original position, with a clever design. In this embodiment, plungers 41 are arranged for limiting at both the front and rear positions of the second fixed block 31. In other embodiments, the arrangement position and quantity of the plungers 41 can also be adjusted according to actual requirements.

[0033] As Figure 4As shown in the figure, a positioning groove 13 matching the fixture 5 is longitudinally opened in the middle of the bottom plate 1 of this embodiment. The fixture 5 is placed in the positioning groove 13. The design of the positioning groove 13 enables the fixture 5 to be accurately placed at the specified position on the bottom plate 1, avoiding the sliding or offset of the fixture 5 on the bottom plate 1, and ensuring the stability of the magnetic component during the pressure holding process. Step surfaces 14 are respectively provided at the front and rear ends of the positioning groove 13, and the limiting blocks 33 are fixedly arranged in the step surfaces 14.

[0034] As Figure 6 shown in the figure, this embodiment further includes a fixture cover plate 7. A rib 71 is provided at the position of the fixture cover plate 7 that matches the Halbach magnetic component 6. The fixture cover plate 7 covers the fixture 5, and the rib 71 is used to press the Halbach magnetic component 6. The rib 71 on the cover plate can further hold the pressure on the Halbach magnetic component 6 on the fixture 5, improving the quality of the product.

[0035] The usage process of the present utility model is as follows:

[0036] The operator places the side of the Halbach magnetic component 6 bonded with the iron part facing upwards, and successively places it in the fixture 5. Then, the fixture 5 is placed in the positioning groove 13 of the bottom plate 1, and the fixture cover plate is covered. The rib 71 on the fixture cover plate abuts against the Halbach magnetic component 6. The operator pushes the first fixing block 21 and the second fixing block 31 with both hands respectively, as Figure 7 shown in the figure.

[0037] Since the first slide rail 25 is horizontally fixedly arranged on the left side of the bottom plate 1, the first slider 26 is horizontally slidably arranged on the first slide rail 25, the first fixing block 21 is fixedly arranged on the first slider 26, and when the first push rod 221 of the first push plate 22 driven by the first slider 26 along the first slide rail 25 horizontally slides on the bottom plate 1 and abuts against one end of the Halbach magnetic component 6 on the fixture 5, the spring pin 42 at one end of the plunger 41 is embedded in the first limiting blind hole 11, realizing the pressure holding on one end of the Halbach magnetic component 6.

[0038] Since the third slide rail 36 is horizontally fixedly arranged on the right side of the bottom plate 1, the third slider 37 is horizontally slidably arranged on the third slide rail 36, the second fixing block 31 is slidably arranged on the third slider 37, and when the second push rod 321 of the second push plate 32 driven by the second fixing block 31 along the third slide rail 36 horizontally slides on the bottom plate 1 and abuts against the other end of the Halbach magnetic component 6 on the fixture 5, the spring pin 42 at one end of the plunger 41 is embedded in the second limiting blind hole 12, realizing the pressure holding on the other end of the Halbach magnetic component 6. And, the second push plate 32 is horizontally slidably arranged on the second fixing block 31, and the buffer spring 34 is arranged between the side of the second push plate 32 away from the fixture 5 and the second fixing block 31, enabling the second push rod 321 to fully press the other end of the Halbach magnetic component 6.

[0039] After the pressure-holding operation is completed, the operator can place the entire device in an oven or other equipment to accelerate the curing of the glue. After the glue is cured, the operator only needs to lift the pull rings 43 on the first pushing device 2 and the second pushing device 3, so that the ejector pin 42 retracts into the plunger 41. Under the action of the first return spring 24 and the second return spring 35, the first fixing block 21 and the second fixing block 31 will be pushed back to their original positions together with the first push rod 221 and the second push rod 321 respectively, and thus all operations are completed.

They are relative concepts, and thus may change accordingly depending on their different positions and different usage states. Therefore, these or other orientation terms should not be construed as restrictive terms.
