Description

Technical Field

[0001] This utility model relates to the field of press-fitting fixtures, and more specifically, to a magnetic ring fan blade press-fitting fixture for preventing damage to the magnetic ring. Background Technology

[0002] Traditional press-fitting methods often have problems in the assembly of magnetic rings and fan blades. Chinese Utility Model Patent Application No. CN202322450637.8 proposes a fan blade structure stabilizing and limiting magnetic ring, comprising an inner magnetic ring and an outer magnetic ring. The outer sidewall of the inner magnetic ring is fixedly connected to the inner sidewall of the outer magnetic ring via multiple fixing brackets, each bracket having limiting holes. The inner sidewall of the inner magnetic ring has multiple inner limiting grooves arranged in a ring array, and the outer sidewall of the outer magnetic ring has multiple outer limiting grooves arranged in a ring array. A heat dissipation layer is also provided between adjacent fixing brackets, fixedly connected to the inner sidewall of the outer magnetic ring, and multiple spaced heat dissipation plates are fixedly connected inside the heat dissipation layer. This utility model utilizes the interaction between the limiting holes, inner limiting grooves, and outer limiting grooves.

[0003] However, existing magnetic ring fan blade pressing fixtures have some shortcomings that need improvement. During the pressing of the magnetic ring into the fan blade, the lack of effective buffering and protection mechanisms makes the magnetic ring susceptible to damage from excessive pressure, leading to decreased product quality and a lower yield rate. This not only increases production costs but also affects product performance and reliability.

[0004] Furthermore, existing press-fitting equipment may suffer from insufficient stability during operation, affecting the accuracy and consistency of press-fitting and consequently impacting product quality. Moreover, the structural design of this equipment may be inadequate, and its operation may be cumbersome, resulting in low assembly efficiency and failing to meet the demands of high-efficiency production.

[0005] Meanwhile, existing press-fitting equipment may also present maintenance difficulties, with inconvenient disassembly and replacement of components, increasing maintenance costs and time. Furthermore, these devices lack versatility and flexibility, often only suitable for press-fitting magnetic rings and fan blades of specific specifications, limiting their application in various production scenarios. Therefore, we propose an improvement: a magnetic ring and fan blade press-fitting fixture that prevents damage to the magnetic ring. Utility Model Content

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0026] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely illustrates some embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model. It should be noted that, in the absence of conflict, the embodiments and features and technical solutions in the embodiments of this utility model can be combined with each other. It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0027] Example 1: Please refer to Figures 1-6 A magnetic ring fan blade press-fitting fixture for preventing crushing of magnetic rings includes a press-fitting fixture fixing rod 1, an upper end cover 2 installed at the top of the press-fitting fixture fixing rod 1, a press head seat sleeve 4 installed on the outer surface of the bottom end of the press-fitting fixture fixing rod 1, a press head seat 5 provided at the bottom of the press head seat sleeve 4, and an internal hexagonal head stop screw 6 connected to the inner cylinder side wall of the press head seat sleeve 4.

[0028] The upper surface of the upper cover 2 is provided with a cover plate fixing hole 3, into which a fastening screw can be inserted. As a preferred technical solution of this utility model, the pressure head seat sleeve 4 and the pressure head seat 5 are connected by an internal hexagon socket head cap screw, and the internal hexagon socket head cap retaining screw 6 connects the pressure head seat sleeve 4 and the guide shaft 9.

[0029] A pressure head 7 is provided below the pressure head seat 5, and the pressure head seat 5 is embedded in the bottom end of the pressing fixture fixing rod 1.

[0030] The pressure head sleeve 4 is connected to the guide shaft 9. The pressing fixture fixing rod 1 and the pressure head 7 are connected by another guide shaft. The guide shaft 9 is set to 3 sections. The middle section of the guide shaft 9 is fixed to the pressure head 7 by the internal hexagonal head screw 10, and the two side sections of the guide shaft 9 are fixed to the pressure head sleeve 4 by the internal hexagonal head stop screw 6.

[0031] A hexagonal head screw 10 is fixedly connected above the pressure head 7. An internal compression spring 11 is nested outside the hexagonal head screw 10. The internal compression spring 11 runs longitudinally through the pressing fixture fixing rod 1, and the top of the spring is connected to the bottom surface of the upper end cover 2.

[0032] A retaining ring 12 is nested on the outer surface of the pressing fixture fixing rod 1, and an external compression spring 13 is provided between the pressing fixture fixing rod 1 and the retaining ring 12. A fan blade 14 is provided below the pressing head 7.

[0033] The working principle of the magnetic ring fan blade press fixture for preventing crushing is as follows: First, the magnetic ring is attracted to the press head 7 by its magnetism. At this time, one end face of the press head seat 5 is in contact with the end face of the magnetic ring.

[0034] When the pressing fixture fixing rod 1 moves downward, the pressing head 7 first reaches the bottom of the inner side of the fan blade 14. As the pressing fixture fixing rod 1 continues to move downward, the internal compression spring 11 nested on the outside of the hexagon socket head cap screw 10 fixedly connected above the pressing head 7 is compressed. At this time, the pressing head 7 can slide relative to the pressing head seat 5 and the pressing fixture fixing rod 1.

[0035] The pressing fixture fixing rod 1 continues to move downwards, and the pressing head seat 5 presses the magnetic ring into the fan blade 14. When the magnetic ring is pressed to the bottom of the fan blade 14, since the pressing head seat 5 and the pressing head 7 are slidable, and the pressing head seat 5 is connected to the pressing head seat sleeve 4, and one end of the external compression spring 13 is connected to the pressing head seat sleeve 4, the external compression spring 13 is compressed, and the pressing head seat 5 stops moving. At this time, the magnetic ring is only subjected to the pressure of the external compression spring 13, which is less than the pressure that would damage the magnetic ring, thus achieving the purpose of protecting the magnetic ring from being crushed.

[0036] The specific working process of the magnetic ring fan blade press-fit fixture for preventing crushing magnetic rings:

[0037] Preparation: Attach the magnetic ring to the pressure head 7 using its magnetism, ensuring that one end face of the pressure head seat 5 is in contact with the end face of the magnetic ring.

[0038] Start pressing: Push the pressing fixture fixing rod 1 downwards. The pressing head 7 first reaches the bottom of the inner side of the fan blade 14.

[0039] The internal compression spring 11 is compressed: As the pressing fixture fixing rod 1 continues to move downward, the pressing head 7 slides relative to the pressing head seat 5 and the pressing fixture fixing rod 1, which compresses the internal compression spring 11 nested on the outside of the internal hexagonal head screw 10.

[0040] Magnetic ring pressed into fan blade: The fixing rod 1 of the pressing fixture continues to move downward, and the pressing head seat 5 presses the magnetic ring into the fan blade 14.

[0041] External compression spring 13 compression: When the magnetic ring is pressed to the bottom of the fan blade 14, the pressure head seat 5 and the pressure head 7 slide relative to each other. Since the pressure head seat 5 is connected to the pressure head seat sleeve 4, one end of the external compression spring 13 is connected to the pressure head seat sleeve 4. At this time, the external compression spring 13 is compressed.

[0042] Pressing complete: Press head seat 5 stops moving. At this time, the magnetic ring is only subjected to the pressure of the external compression spring 13, and this pressure is less than the pressure that would damage the magnetic ring, thus protecting the magnetic ring from being crushed and completing the pressing work between the magnetic ring and the fan blade.

[0043] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
