Description

Technical Field

[0001] The utility model relates to the technical field of permanent magnets, in particular to an assembly structure of a radial permanent magnet component. Background Art

[0002] Permanent magnet assembly can be spliced ​​into a 360° ring by using glue (glue type: epoxy glue, high-temperature glue, etc.) through segmented permanent magnets (permanent magnet types: NdFeB, SmCo, AlNiCo or ferrite) at a certain angle (radial, oblique magnetization direction). The outer circle is fixed by a fixing ring (magnetic conductive material or non-magnetic conductive material, magnetic conductive material grades 1010, DT4, etc., non-magnetic conductive material grades titanium alloy, stainless steel 304, etc.). In specific applications, the spatial magnetic field in the inner circle is mainly used.

[0003] However, when assembling the permanent magnet assembly, since this type of permanent magnet assembly cannot be magnetized after assembly, the non-magnetic assembly method cannot be used. Therefore, the magnetic assembly of the permanent magnet is difficult. The permanent magnets have strong repulsive forces with each other under strong magnetism, and the radial and axial positioning accuracy of the permanent magnet assembly is high, so it is difficult to ensure the accuracy by direct bonding. In the absence of tooling to assist in assembly, the assembly efficiency is low and it is easy to be damaged. Therefore, a radial permanent magnet assembly structure is proposed. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies of the prior art, the utility model provides an assembly structure of a radial permanent magnet assembly, which solves the problems raised in the above background technology.

[0006] (II) Technical solution

[0007] To achieve the above purpose, the utility model is implemented through the following technical solutions: a radial permanent magnet component assembly structure, including a frame, a detachable placement frame assembly is provided in the frame, the placement frame assembly can be used to place the radial permanent magnet structure, the radial permanent magnet structure includes a long fixed ring and a permanent magnet group, the permanent magnet group is arranged in the long fixed ring, the long fixed ring is also provided with a fixing column for positioning the permanent magnet group, the outside of the long fixed ring is provided with a short fixed ring that can be connected to the long fixed ring, the frame is provided with a pressure plate that can move up and down along the frame, and the radial permanent magnet structure can be provided with a pressing block for pressing the radial permanent magnet structure.

[0008] Furthermore, the placement rack assembly includes an arc-shaped support plate, and the arc-shaped support plate is arranged in the frame at intervals in a ring shape.

[0009] Furthermore, the arc-shaped support plates arranged at intervals in a ring shape can be detachably installed in the frame and are used to support the radial permanent magnet structure.

[0010] Furthermore, the radial permanent magnet structure may be provided with a permanent magnet group replacement module for replacing the permanent magnet group, and the outside of the short fixing ring may be provided with locking bolts for positioning and locking the permanent magnet group or the permanent magnet group replacement module.

[0011] Furthermore, the locking bolts are arranged in a one-to-one correspondence with the permanent magnet groups or permanent magnet group replacement modules.

[0012] Furthermore, the permanent magnet group is composed of permanent magnet blocks that are continuously arranged in sequence, and the permanent magnet blocks that are continuously arranged in sequence can be spliced ​​into a 360° annular shape and form a circular ring. The permanent magnet group replacement module is composed of permanent magnet replacement modules that are continuously arranged in sequence, and the permanent magnet replacement modules that are continuously arranged in sequence can be spliced ​​into a 360° annular shape and form a circular ring.

[0013] Furthermore, a pressing plate control rod for controlling the pressing plate to move up and down is provided on the frame, and a handle is provided on the top of the pressing plate control rod.

[0014] Radial permanent magnet structure assembly instructions:

[0015] This solution can splice permanent magnet group replacement modules that are similar in shape to the permanent magnet group into a 360° circumferential shape. By placing fixing columns in the magnet group replacement module, the inner circle accuracy of the subsequent permanent magnet group assembly can be guaranteed. The long fixing ring set on the outer surface of the magnet group replacement module can ensure the outer circle accuracy of the subsequent permanent magnet group. Installing a short fixing ring on the outer surface of the long fixing ring can control the deformation of the long fixing ring of the permanent magnet group, which is convenient for the installation of the permanent magnet group. By setting locking bolts on the outside of the short fixing ring, the accuracy of the permanent magnet group in the radial direction can be guaranteed.

[0016] By installing the placement frame assembly in the frame, the overall structure of the radial permanent magnet structure replaced by the permanent magnet group replacement module can be placed in the frame, and then glue can be applied to the outer cylindrical surface and two side surfaces of the permanent magnet block, and then it is placed on the upper surface position of the placement frame assembly, and then the pressure plate is driven downward by the pressure plate control rod until the permanent magnet block is pressed down into place, so that the permanent magnet group replacement module is moved out from the bottom, and then the locking bolts are tightened to fix the radial position of the permanent magnet block, and then the above steps are repeated for assembly until the 360° overall splicing process is completed.

[0017] After completing the 360° spliced ​​radial permanent magnet structure, it is necessary to disassemble the lower placement frame assembly so that the radial permanent magnet structure can be placed in the frame, and then a clamping block can be placed on top of it. At this time, the pressure plate control rod can be pressed so that the pressure plate can press the clamping block downward, which can play a limiting role until the glue is cured and the overall assembly of the component is completed.

[0018] Compared with the prior art, the radial permanent magnet assembly structure not only ensures the radial and axial accuracy of the installed radial permanent magnets, but also facilitates the assembly of the radial permanent magnets to be magnetized, thereby improving the assembly efficiency.
