[0035] Please also read Figures 1 to 5 Now, a fan motor magnetic shoe press-fitting device provided in an embodiment of the present application is described. The fan motor magnetic shoe press-fitting device comprises a bottom plate 101, a push plate 102, a slide table 103, a guide cylinder mold 105 and a U-shaped spring 110. Among them:

[0036] The push plate 102 is connected to the bottom plate 101 , the slide 103 is slidably connected to the push plate 102 , and a main spring 104 is connected between the slide 103 and the bottom plate 101 to make the slide 103 and the bottom plate 101 tend to move away from each other. The guide cylinder mold 105 is installed on the slide 103 and forms a first annular side wall 106 for fitting the magnetic tile 201 and a second annular side wall 107 coaxially arranged with the first annular side wall 106. The axial direction of the guide cylinder mold 105 is parallel to the sliding direction of the slide 103 relative to the push plate 102. The second annular side wall 107 is larger than the radial dimension of the first annular side wall 106 and forms a step surface 108 with the first annular side wall 106 for abutting against the magnetic tile 201. The guide cylinder mold 105 is recessed along its own radial direction from the surface of the second annular side wall 107 to form a notch 109 for the push plate 102 to pass through. The notch 109 extends to the step surface 108 and the bottom of the notch 109 is flush with the first annular side wall 106. Gaps are formed between the push plate 102 and the side walls of the guide cylinder mold 105 on both sides for forming the notch 109 along the circumference of the second annular side wall 107. The U-shaped spring 110 overlaps one end of the push plate 102 close to the notch 109 and extends into the gaps on both sides of the push plate 102 .

[0037] According to the above structure provided in this embodiment, the guide cylinder mold 105 forms a first annular side wall 106 and a second annular side wall 107 which are coaxially arranged. The magnetic tile 201 to be installed in the motor housing 202 can be pre-set on the first annular side wall 106 and abut against the step surface 108 between the first annular side wall 106 and the second annular side wall 107. Then, the motor housing 202 is axially inserted from the top of the guide cylinder mold 105 and continuously pressed downward by an axial external force, so that the magnetic tile 201 enters the motor housing 202. When the magnetic tile 201 is adsorbed on the first annular side wall 106, there is a set gap between the outer wall thereof and the inner wall of the motor housing 202, and the motor housing 202 can be easily inserted into the magnetic tile 201. When the magnetic tile 201 enters the motor housing 202 and the upper end surface of the magnetic tile 201 abuts against the bottom surface of the motor housing 202, the motor housing 202 will drive the guide cylinder mold 105 and the slide 103 downward under the continued action of external force; that is, the motor housing 202 can be driven by the magnetic tile 201 abutting against the step surface 108. The movable guide cylinder mold 105 moves and drives the slide 103 to move downward relative to the push plate 102, so that the U-shaped spring 110 overlapped on the push plate 102 enters the motor housing 202 and supports the two sides of the magnetic tile 201 that has been installed in the motor housing 202, so that the outer wall of the magnetic tile 201 is tightly attached to the inner wall of the motor housing 202 to achieve the fixation of the magnetic tile 201 in the motor housing 202. Usually, the outer wall of the magnetic tile 201 is also coated with an adhesive, and the magnetic tile 201 is pressed tightly against the motor housing 20 through the U-shaped spring 110. 2, after curing for a set time, the U-shaped spring 110 can be taken out of the motor housing 202 for repeated use; at the same time, when the U-shaped spring 110 presses the magnetic tile 201 against the inner wall of the motor housing 202, the inner wall of the magnetic tile 201 and the first annular side wall 106 naturally form a clearance fit, so after the external force pressing the motor housing 202 to the guide cylinder mold 105 disappears, the motor housing 202 with the magnetic tile 201 installed can be easily removed from the guide cylinder mold 105, which is convenient to operate. Since the posture of the U-shaped spring 110 entering the motor housing 202 in the present application is pre-restricted by the push plate 102 and the second annular side wall 107, it can quickly adapt to the magnetic tile 201 in the motor housing 202, significantly improving the assembly efficiency of the fan motor magnetic tile, which is far superior to the prior art.

[0038] To further explain, after the U-shaped spring 110 is installed into the motor housing 202 and supports and fixes the magnetic tile 201, the external force acting on the motor housing 202 can be removed and the slide 103 can slide upward relative to the push plate 102 under the elastic restoring force of the main spring 104, so that the slide 103 can drive the guide cylinder mold 105 and the motor housing 202 with the magnetic tile 201 assembled away from the push plate 102 and separate the push plate 102 from the U-shaped spring 110. After removing the motor housing 202 with the magnetic tile 201 and the U-shaped spring 110 installed, the fan motor magnetic tile pressing device provided in this embodiment can be used to perform the next assembly operation of the magnetic tile 201 and the U-shaped spring 110.

[0039] In another embodiment of the present application, please refer to Figures 1 to 5 The surface of the first annular side wall 106 is protruded with a limiting guide bar 111 for limiting the movement of the magnetic tile 201 in the circumferential direction relative to the first annular side wall 106 and relative to the guide cylinder mold 105, and the bottom of the notch 109 is flush with the limiting guide bar 111. According to the above structure provided in this embodiment, the limiting guide bar 111 can limit the movement of the magnetic tile 201 in the circumferential direction of the first annular side wall 106, so that the position of the magnetic tile 201 and the position of the U-shaped spring 110 can be more adapted, which is conducive to further improving the assembly efficiency of the magnetic tile 201 of the fan motor magnetic tile press-fitting device in this embodiment.

[0040] In another embodiment of the present application, please refer to Figures 1 to 5 A slide groove 112 parallel to the axial direction of the guide cylinder mold 105 is formed on the first annular side wall 106. The fan motor magnetic shoe press-fitting device also includes a top spring rod 113 slidably connected in the slide groove 112 and provided with sliding guidance by the slide groove 112. The top spring rod 113 abuts against the push plate 102 and can be driven by the push plate 12 to move in the slide groove 112. The U-shaped spring 110 is overlapped on the top spring rod 113. According to the above structure provided in this embodiment, the top spring rod 113 guided by the slide groove 112 can drive the U-shaped spring 110 to be installed in the motor housing 202 more stably and quickly, which is conducive to further improving the assembly efficiency of the magnetic shoe 201 of the fan motor magnetic shoe press-fitting device in this embodiment.

[0041] In another embodiment of the present application, please refer to Figures 1 to 5, a receiving chamber 114 connected to the slide slot 112 is formed inside the guide cylinder mold 105, and the fan motor magnetic shoe pressing device also includes a sliding core 115 movably arranged in the receiving chamber 114 and a reset spring 116 connected between the sliding core 115 and the guide cylinder mold 105, and the top spring rod 113 is connected to the sliding core 115 and can always abut against the push plate 102 under the elastic force of the reset spring 116. According to the above structure provided in this embodiment, the reset spring 116 can always abut the top spring rod 113 on the push plate 102 during the separation process of the push plate 102 and the U-shaped spring 110, which significantly facilitates the recycling of the fan motor magnetic shoe pressing device in this embodiment. Of course, in other embodiments of the present application, the sliding core 115 can also be set to be able to move in the receiving chamber 114 under the action of its own gravity so as to always abut the top spring rod 113 on the push plate 102, which has the same technical effect as this embodiment, and will not be repeated here.

[0042] In another embodiment of the present application, please refer to Figures 1 to 5 The guide cylinder mold 105 is installed on the side of the slide 103 away from the bottom plate 101 and is located at the center of the slide 103. The push plate 102 passes through the slide 103 to extend into the notch 109 formed on the guide cylinder mold 105. According to the above structure provided in this embodiment, the slide 103 can slide more stably relative to the push plate 102, which is conducive to further improving the assembly efficiency of the magnetic shoe 201 of the fan motor magnetic shoe press-fitting device in this embodiment.

[0043] In another embodiment of the present application, please refer to Figures 1 to 5 The fan motor magnetic shoe press-fitting device further includes a guide post 117 coaxially sleeved inside the main spring 104 and connected to the bottom plate 101. The guide post 117 movably passes through the slide 103 and is connected to a pressing plate 118 and a bolt 119 at the end away from the bottom plate 101 to restrict the slide 103 on the guide post 117. According to the above structure provided in this embodiment, the guide post 117 can make the slide 103 slide more stably relative to the push plate 102, which is conducive to further improving the assembly efficiency of the magnetic shoe 201 of the fan motor magnetic shoe press-fitting device in this embodiment.

[0044] In another embodiment of the present application, please refer to Figures 1 to 5The fan motor magnetic shoe press-fitting device also includes a pressing head 120 which is spaced relative to the guide cylinder mold 105 and can approach or move away from the guide cylinder mold 105. The moving direction of the pressing head 120 relative to the guide cylinder mold 105 is parallel to the sliding direction of the slide 103 relative to the push plate 102. According to the above structure provided in this embodiment, the pressing head 120 can be driven by a compressed air cylinder, a hydraulic cylinder or other linear drive mechanism commonly used in the art to generate an axial external force to make the motor housing 202 axially insert from the top of the guide cylinder mold 105, that is, the motor housing 202 can be automatically driven to move toward the guide cylinder mold 105 and complete the assembly of the magnetic shoe 201. Compared with the manual operation method, the assembly efficiency of the magnetic shoe 201 of the fan motor magnetic shoe press-fitting device in this embodiment can be further improved.

[0045] In another embodiment of the present application, please refer to Figures 1 to 5 The fan motor magnetic tile press-fitting device further comprises a guide seat 121 slidably connected to the bottom plate 101, and the movement direction of the bottom plate 101 relative to the guide seat 121 is perpendicular to the movement direction of the pressing head 120.
