Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment installation, in particular to a front bearing and rotor lamination pressing tooling. Background Art

[0002] A bearing is an important component in contemporary mechanical equipment. Its main function is to support a mechanical rotating body, reduce the friction coefficient during the movement of the mechanical rotating body, and ensure its rotational accuracy.

[0003] The existing bearing pressing tooling directly places the shaft on the bearing along the bearing axis direction. During the pressing process, the shaft is prone to shaking and inaccurate positioning, which can easily cause the bearing to be damaged and the bearing to fly and injure people. Moreover, the coaxial alignment of the laminations is the most difficult to control during the bearing pressing process. Therefore, an auxiliary tooling is needed to position the bearing and the laminations, so as to ensure the stability and accuracy during the bearing pressing process. Therefore, a front bearing and rotor lamination pressing tooling is needed. Summary of the Utility Model

[0004] In view of the above-mentioned disadvantages of the prior art, the purpose of the present utility model is to provide a front bearing and rotor lamination pressing tooling for solving the problem of bearing positioning during bearing pressing in the prior art.

[0005] To achieve the above purpose and other related purposes, the present utility model provides the following technical solutions:

[0008] A bearing base, in which a rotor seat for carrying a rotor and a bearing seat for carrying a bearing are provided. The bearing seat is located below the rotor seat. The bearing seat, the elastic guiding rod and the rotor seat are coaxially arranged. And when the bearing base is placed on the pressing base, the elastic guiding rod extends into the bearing seat;

[0009] An upper cover covering the upper side of the bearing base.

[0010] By implementing the above technical solutions, the positioning during the assembly of the bearing and the laminations is realized by setting the pressing base in cooperation with the bearing base. The rotor seat of the bearing base is used to carry the rotor to ensure the stability of the rotor during assembly, and the bearing seat carries the bearing to ensure the coaxiality of the bearing and the rotor. In order to ensure the installation stability of the bearing, an elastic guiding rod is provided in the pressing base. When the bearing base is placed on the pressing base, the elastic guiding rod extends into the bearing seat.

[0011] When assembling the bearing, place the bearing base on the press-fitting base, open the upper cover. At this time, it can be seen that the elastic guide rod extends into the bearing seat. Place the bearing and laminations to be assembled into the bearing seat in sequence, then place the rotor into the rotor seat, insert the main shaft, cover the upper cover on the press-fitting base, and press down the main shaft by an external pressing rod, so as to push the main shaft downward into the installation position.

[0016] In an embodiment of the present invention, an air guide through hole is provided in the bearing base below the return spring, and the air guide through hole communicates the inside of the spring groove with the outside.

[0017] To implement the above technical solution, the air guide through hole can prevent the air in the spring groove from being compressed during the downward displacement of the elastic guide rod, resulting in too high a temperature in the spring groove and affecting the use stability of the equipment.

[0018] In an embodiment of the present invention, a base groove that is recessed inward is provided on the upper side of the press-fitting base, and the bearing base is embedded in the base groove.

[0019] To implement the above technical solution, by providing the base groove, it can provide stable support for installing the bearing base on the press-fitting base and ensure the assembly stability between the bearing base and the press-fitting base during the press-fitting process.

[0020] In an embodiment of the present invention, a bearing groove that is recessed inward is provided at the center of the base groove.

[0024] In an embodiment of the present utility model, a horn-shaped guide platform is provided on the inner wall of the inlet side of the bearing seat.

[0025] By implementing the above technical solution, the setting of the horn-shaped guide platform can provide guidance for placing the bearing into the bearing seat, thereby improving the convenience of placing the bearing into the bearing seat.

[0026] In an embodiment of the present utility model, a guide rod through hole is provided below the bearing seat in the bearing base, and the radial dimension of the guide rod through hole is set to be larger than the radial dimension of the elastic guide rod.

[0027] By implementing the above technical solution, setting the radial dimension of the guide rod through hole to be larger than the radial dimension of the elastic guide rod can improve the convenience of the guide rod extending into the bearing base.

[0028] As described above, the front bearing and rotor lamination pressing tooling of the present utility model has the following beneficial effects: by setting the pressing base in cooperation with the bearing base, the positioning during the assembly of the bearing and the lamination is realized.
