Detailed Implementation
[0022] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.
[0023] like Figure 1-3 As shown, in one embodiment of this utility model, the magnet attaching device 100 includes a bracket 10, a drive assembly 20, and a magnet positioning fixture 50. The magnet positioning fixture 50 is provided with a limiting groove 51 for placing a magnet 42. The bracket 10 includes an operating plate 11, the surface of which is used to fix the magnetic yoke 41, and an opening is made in the operating plate 11 for the magnet positioning fixture 50 to pass through. When the magnetic yoke 41 is fixed to the operating plate 11, it is coaxial with the opening of the operating plate 11. The drive assembly 20 is mounted on the bracket 10, and it connects to and drives the magnet positioning fixture 50 to pass through the opening from below the operating plate 11 and move to above the operating plate 11 to enter the magnetic yoke 41.
[0024] The shape of the limiting groove 51 is the same as the shape of the magnet 42, for example... Figure 1 and 2In the design, the limiting groove 51 is a strip-shaped groove with a width equal to (or slightly greater than) the width of the magnet 42, and open at both ends to allow the magnet 42 to enter and exit. When attaching the magnet 42, the magnetic yoke 41 is first fixed to the operating plate 11, and then structural adhesive is applied to the inner wall of the magnetic yoke 41. At this time, the magnet positioning fixture 50 is located below the operating plate 11. After the structural adhesive is applied, the drive assembly 20 drives the magnet positioning fixture 50 upward to the inside of the magnetic yoke 41 above the operating plate 11. The space between the limiting groove 51 and the magnetic yoke 41 is the attachment position for the magnet 42. The magnet 42 is then inserted between the limiting groove 51 and the inner wall of the magnetic yoke 41. After the structural adhesive has solidified, the drive assembly 20 drives the magnet positioning fixture 50 downward to the bottom of the operating plate 11.
[0025] The magnet attaching device 100 has a simple structure, allowing operators to quickly attach magnets 42. The magnet positioning fixture 50 is driven to move by the drive assembly 20, thus avoiding situations where the magnet 42 gets stuck in the limiting groove 51 or even detaches from the surface of the yoke 41 due to improper control of the moving angle during manual movement. This further improves the stability of the attachment process and ensures production rhythm and efficiency.
[0026] In other embodiments, the limiting groove 51 may also be configured to be open at the top and closed at the bottom to prevent the magnet 42 from detaching from the preset attachment position when inserted.
[0027] Preferably, the bracket 10 also includes a magnetic yoke positioning plate 13 that can be detachably fixed to the operating plate 11. The magnetic yoke positioning plate 13 also has openings for the magnetic steel positioning fixture 50 to pass through. When fixed to the operating plate 11, the openings on the magnetic yoke positioning plate 13 are coaxial with the openings on the operating plate 11. When fixing the magnetic yoke 41, the magnetic yoke positioning plate 13 can be removed from the operating plate 11, the magnetic yoke 41 can be fixed to the magnetic yoke positioning plate 13, and then the magnetic yoke positioning plate 13 can be fixed to the operating plate 11, thus making it easier for the operator to operate.
[0028] Furthermore, a handle is installed on the magnetic yoke positioning plate 13, which makes it easier and less strenuous to move the magnetic yoke positioning plate 13 and the magnetic yoke 41, thereby improving production efficiency and preventing operators' fingers from being pinched.
[0029] In one embodiment, the magnet positioning fixture 50 includes a fixture fixing plate 52 and an attachment sleeve 53 detachably fixed to the fixture fixing plate 52, with a limiting groove 51 formed on the outer wall of the attachment sleeve 53. When replacing magnets 41 and magnets 42 of different sizes and specifications, quick adaptation can be achieved by replacing the corresponding magnet positioning plate 13 (the opening diameter of the magnet positioning plate 13 is not less than the inner diameter of the magnet 41) and the attachment sleeve 53 (the outer diameter is adapted to the inner diameter of the magnet 41, and the width of the limiting groove 51 is adapted to the width of the magnet 42), which provides greater flexibility.
[0030] The bracket 10 also includes a drive plate 14 and a base plate 15 sequentially disposed below the operation panel 11, the base plate 15 and the operation panel 11 being fixedly connected (e.g.) Figure 1 (As shown in the diagram, the two are connected at their corners by a support rod). A first bearing seat 16 with a built-in bearing is provided on the base plate 15, and a threaded sleeve 17 with built-in threads is provided on the drive plate 14. The drive assembly 20 includes a lead screw 21, a handwheel 22, and a drive rod 23. The lead screw 21 passes through the threaded sleeve 17, and one end of it is fixed to the bearing in the first bearing seat 16. The handwheel 22 is fixed to the end of the lead screw 21 away from the threaded sleeve 17. The tooling fixing plate 52 is fixed to the drive plate 14. By rotating the handwheel 22, the drive plate 14 moves up and down under the action of the thread, thereby driving the magnetic positioning tooling 50 to move up and down on both sides of the operating plate 11.
[0031] Preferably, the bracket 10 further includes a support plate 18 disposed between the drive plate 14 and the operation plate 11. The support plate is also fixedly connected to the operation plate 11 by a support rod at its corner position. A second bearing seat 12 with a built-in bearing is provided on the support plate 18. The other end of the lead screw 21 is fixed to the bearing in the second bearing seat 12, while the drive rod 23 passes through the support plate 18 and is connected to the tooling fixing plate 52. The support plate 18 is used to limit the movement of the drive rod 23 to the vertical direction only, avoiding swaying in other directions. At the same time, the second bearing seat 12 cooperates with the first bearing seat 16 to prevent the lead screw 21 from swaying, ensuring that the magnetic positioning tooling 50 moves only in the vertical direction, thereby further improving stability.
[0032] Preferably, there are two drive rods 23, which are respectively located on both sides of the lead screw 21 to ensure that the magnet positioning fixture 50 moves in a horizontal position and prevents tilting.
[0033] In one embodiment, the lead screw 21 has a three-section design, including a threaded section in the middle and smooth sections at both ends. The smooth sections at both ends can be better fixed to the bearings in the first bearing housing 16 and the second bearing housing 12 to avoid the surface threads from sliding directly with the bearings.
[0034] In other embodiments, in addition to the driving method described above, a cylinder can be installed on the base plate 15 to directly drive the magnetic positioning fixture 50 to move, or a motor can drive the lead screw 21 to rotate, in order to replace manual operation.
[0035] Preferably, the bottom surface of the base plate 15 is provided with a plurality of support blocks 31, and the height of the support blocks 31 is greater than the maximum distance between the handwheel 22 and the base plate 15. The support blocks 31 are used to raise the base plate 15 to provide sufficient operating space for the handwheel 22.
[0036] Preferably, each support block 31 is provided with a wheel 32, so that the magnet attaching device 100 in this embodiment can be easily and quickly moved to the target position. Secondly, each support block 31 is also provided with a foot support 33, and the fixed position of the foot support 33 in the vertical direction is adjustable. That is, after moving to the target position, the entire device can be supported by the foot support 33, so that the wheels 32 are off the ground. The entire device is supported only by the foot support 33 to prevent unnecessary movement, thereby improving the stability during attachment.
[0037] The above embodiment describes the case where the magnet 42 is attached to the inner wall of the yoke 41. When it is necessary to attach the magnet 42 to the outer wall of the yoke 41, the positions of the yoke 41 and the attachment sleeve 53 can be interchanged. That is, the yoke 41 is first fixed on the tooling fixing plate 52 and structural adhesive is applied. Then the attachment sleeve 53 (the limiting groove 51 is opened on the inner wall) is fixed on the operating plate 11 or the yoke positioning plate 13. The driving assembly 20 drives the tooling fixing plate 52 to move up to above the operating plate 11 and inserts the magnet 42 into the space between the limiting groove 51 and the outer wall of the yoke 41.
[0038] It will be apparent to those skilled in the art that this disclosure is not limited to the details of the exemplary embodiments described above, and that this disclosure can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of this disclosure is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this disclosure.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
