[0020] The following description is only intended to disclose the present invention so that those skilled in the art can implement it. The embodiments in the following description are merely examples, and those skilled in the art will conceive of other obvious modifications. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other solutions that do not depart from the spirit and scope of the present invention.

[0021]

Example 1

[0022] A press-fitting fixture for a motor magnet frame assembly, such as Figure 1 , Figure 2 It includes a housing positioning seat 4, a frame positioning seat 7, a guide rod 3 and a support spring 5, and a disc-shaped base 9 is provided at the bottom of the frame positioning seat 7.

[0023] To ensure the housing positioning seat 4 can be supported from above, three support springs 5 ​​of the same height and corresponding to the outer diameter of the guide post are fitted onto the guide rod 3. This stabilizes the housing positioning seat 4. After the press presses the housing 1 into place, when the press rod retracts, the housing 1 can naturally push out along the plane of the press rod due to the rebound force, improving assembly efficiency. Three sets of guide rods 3 are provided, with the lower end connected to the base 9 and the upper end passing through the housing positioning seat 4. One set is the reference guide rod 31, which has a diameter 1mm larger than the other two and can be selected at a higher height. This ensures a unique reference and effectively avoids angular errors caused by incorrect references.

[0024] The housing positioning base 4 is provided with a through hole 41 and a number of housing positioning bosses 43. The housing positioning bosses 43 are arranged around the through hole 41. The through hole 41 is a channel for the magnet skeleton assembly 6 to pass through during press fitting. At least one housing reference boss 42 is provided among the number of housing positioning bosses 43. The housing reference boss 42 can be set on the same side as the reference guide rod 31 or at other required angles. The width of the housing reference boss 42 is greater than the width of other non-reference housing positioning bosses, so that the housing 1 is oriented in a unique way and avoids incorrect placement of the housing 1 at an angle.

[0025] Preferably, the edges of the housing positioning boss 43 are all chamfered.

[0026] The skeleton positioning seat 7 is provided with an anti-misalignment groove 72 and a number of skeleton positioning protrusions 71. In this embodiment, there are three sets of skeleton positioning protrusions 71, which correspond to the grooves on the magnet skeleton assembly 6. The magnet skeleton assembly 6 can be positioned at the upper limit. One skeleton positioning protrusion 71 is at a required angle to the reference guide rod 31, such as 0° or other angles. The anti-misalignment groove 72 is provided to correspond to the anti-misalignment protrusions of the magnet skeleton assembly 6, so that the skeleton direction is unique.

[0027] Preferably, the height of the skeleton positioning boss 71 is less than the depth of the groove on the magnet skeleton assembly 6, and the depth of the anti-mistake groove 72 is greater than the height of the anti-mistake protrusion on the magnet skeleton assembly 6, so as to avoid collision with the product during pressing due to product processing errors.

[0028] Preferably, the inner side of the skeleton positioning boss 71 is set as an arc surface, which can reduce the contact area with the magnet skeleton assembly 6 and reduce wear and friction.

[0029] Preferably, the skeleton positioning seat 7 is a cylindrical structure, and the diameter of the cylindrical structure is less than or equal to the diameter of the through hole 41, so that the skeleton positioning seat 7 can avoid impact with the housing positioning seat 4 during press fitting.

[0030] Preferably, the aforementioned reference guide rod 31 and housing reference boss 42 can be provided with marking areas to enhance the differentiation effect from other non-reference structures.

[0031] During press fitting, the housing 1 is placed on the housing positioning seat 4. The four sets of housing positioning bosses 43 on the housing positioning seat correspond to the four grooves set inside the housing 1, which effectively prevents the housing from being reversed and fixes the position angle of the housing, ensuring the uniqueness of the position. The magnet skeleton assembly 6 is placed into the skeleton positioning seat 7. The skeleton positioning boss 71 and the anti-misalignment groove 72 make the skeleton orientation unique. The press is set to the maximum pressing force required. When the pressing rod is pressed in with the required force, the force will stop and the pressing is completed.

[0032] Optionally, in other embodiments, both the housing positioning boss 43 and the frame positioning boss 71 can be configured to be detachable, allowing for convenient adjustment according to the type of product being manufactured.

[0033] A motor frame magnet assembly press-fitting device includes the aforementioned motor magnet frame assembly press-fitting fixture and press.

[0034] According to one embodiment of the present invention, a flexible layer is provided at the end of the press rod of the press. The flexible layer can be a nylon ring. The nylon ring avoids the protrusions at the bottom of the machine housing and effectively prevents wear on the machine housing.

[0035] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functional and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations and modifications.
