DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0024] Please refer to Figures 1-4 The present application provides a fan bearing press fitting machine, which comprises a base 1 and an adjusting part 6.

[0025] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The base 1 is fixedly connected with a support column 2, the top end of the support column 2 is fixedly connected with a top plate 5, the base 1 is provided with a cylinder 4, the cylinder rod end of the cylinder 4 is fixedly connected with a press fitting plate 3, the adjusting part 6 is screwed through the top plate 5 and detachably connected with a top column 7, and the top column 7 is located above the press fitting plate 3. When the bearing 11 of the fan needs to be press fitted, the bearing 11 to be press fitted is first placed on the press fitting plate 3, and then the shaft sleeve 10 is placed on the middle position of the bearing 11. At this time, the lower surface of the top column 7 is brought into contact with the upper surface of the shaft sleeve 10 by rotating the adjusting part 6, and then the cylinder 4 is started to make the press fitting plate 3 rise. Under the double action of the cylinder 4 and the top column 7, the bearing 11 is press fitted on the outside of the shaft sleeve 10, and the press fitting of the fan bearing 11 is realized. Through the action of the cylinder 4, the press fitting plate 3 and the top column 7, the automatic press fitting of the bearing 11 is realized, manual knocking is not needed, the deformation of the bearing 11 can be effectively prevented, and the press fitting efficiency is improved. Through the setting of the adjusting part 6, the height of the top column 7 can be changed, so that it is suitable for press fitting shaft sleeves 10 of various heights. Through the detachable connection of the top column 7 and the adjusting part 6, the specification of the top column 7 can be changed according to bearings 11 and shaft sleeves 10 of different specifications and sizes, so that the top column 7 cannot enter the middle position of the shaft sleeve 10 and cannot press down the shaft sleeve 10, or the top column 7 is too thick and is in contact with the upper surface of the bearing 11 at the same time as being in contact with the upper surface of the shaft sleeve 10, thereby affecting the press fitting of the bearing 11.

[0026] In this embodiment, the adjusting part 6 comprises an adjusting screw 61, the bottom end of the adjusting screw 61 is screwed through the top plate 5 and detachably connected with the top column 7, and the top end of the adjusting screw 61 is provided with a handle 62. When the bearing 11 and the shaft sleeve 10 are both placed on the press fitting plate 3, the handle 62 is held to rotate the adjusting screw 61, so that the top column 7 is in contact with the upper surface of the shaft sleeve 10. After the press fitting is completed, the handle 62 is rotated again to lift the top column 7.

[0027] In the specific setting, the bottom end of the adjusting screw 61 is connected with the connecting column shell 8, and the top column 7 is detachably connected with the connecting column shell 8. The connecting column shell 8 and the top column 7 are jointly provided with a magnetic attraction piece 9. Specifically, the outer side of the top column 7 is fixedly connected with a limiting ring 71, and the outer side of the limiting ring 71 is in contact with the inner wall of the connecting column shell 8, so that the outer side wall of the top column 7 of different specifications is in contact with the inner wall of the connecting column shell 8, thereby increasing the stability of the top column 7 and preventing the top column 7 from tilting when subjected to force. The magnetic attraction piece 9 includes a magnet block 91 and a magnetite 92, which are arranged at the bottom end of the top column 7 and the inside of the connecting column shell 8 respectively, and cooperate with each other. The magnet block 91 is provided with a displacement slot 911 matched with the magnetite 92. When it is necessary to replace the top column 7, the top column 7 is directly removed, and a new top column 7 is placed into the connecting column shell 8. At this time, under the action of the magnet block 91 and the magnetite 92, the top column 7 is adsorbed on the connecting column shell 8, thereby realizing the replaceability of the top column 7.

[0028] In the present embodiment, the press fitting plate 3 is slidingly arranged on each support column 2. Each support column 2 is provided with a square limiting strip plate 21. By slidingly arranging the press fitting plate 3 on each support column 2, the stability of the press fitting plate 3 during upward and downward movement can be ensured. By arranging the square limiting strip plate 21, the press fitting plate 3 will not deviate during upward and downward movement, thereby ensuring the precision of the press fitting of the bearing 11.

[0029] The working principle of the fan bearing press fitting machine is as follows: when it is necessary to press fit the bearing 11 of the fan, the bearing 11 to be press fitted is placed on the press fitting plate 3, and then the shaft sleeve 10 is placed on the bearing 11 at the middle position. At this time, the lower surface of the top column 7 is brought into contact with the upper surface of the shaft sleeve 10 by rotating the adjusting member 6, and then the cylinder 4 is started to make the press fitting plate 3 rise. Under the double action of the cylinder 4 and the top column 7, the bearing 11 is press fitted on the outside of the shaft sleeve 10, thereby realizing the press fitting of the fan bearing 11. By the action of the cylinder 4, the press fitting plate 3 and the top column 7, the automatic press fitting of the bearing 11 is realized, without the need for manual knocking, which can effectively prevent the deformation of the bearing 11 and improve the press fitting efficiency. By arranging the adjusting member 6, the height of the top column 7 can be changed, thereby being suitable for press fitting shaft sleeves 10 of various heights. By detachably connecting the top column 7 and the adjusting member 6, the specifications of the top column 7 can be changed according to bearings 11 and shaft sleeves 10 of different specifications and sizes, thereby preventing the top column 7 from being too thin to enter the middle position of the shaft sleeve 10 and being unable to press the shaft sleeve 10, or being too thick to be in contact with the upper surface of the shaft sleeve 10 while being in contact with the upper surface of the bearing 11, thereby affecting the press fitting of the bearing 11.

[0030] It should be noted that the specific model and specification of the cylinder 4 need to be determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the art, which will not be described in detail.

[0031] The power supply of the cylinder 4 and its principle are clear to those skilled in the art and will not be described in detail here.
