Description

Technical Field

If the pressure is too low, the bearings will not be properly assembled; if the pressure is too high, the rotor shaft with a small diameter will be bent, and small-sized bearings will be easily damaged, resulting in poor rotor production.

[0017] The present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings. Example

[0018] like Figure 1 As shown, a motor bearing servo press device includes a processing table, on which a rotor shaft mechanism, a rotor mechanism, and a servo drive mechanism are mounted, with the rotor mechanism located between the rotor shaft mechanism and the servo drive mechanism; The rotor shaft mechanism includes a rotor shaft and a fixing platform for fixing the rotor shaft; the function of the rotor shaft mechanism is to fix the rotor shaft, and the mechanism serves as a fixed end, which is fixedly installed on the processing platform.

[0019] The rotor mechanism includes a rotor and a centering lifting platform for fixing the rotor. The rotor mechanism is used to fix the rotor. At the same time, the mechanism has a self-centering function in the horizontal direction and a lifting function in the vertical direction, so as to facilitate the adjustment of the bearings inside the rotor to be concentric with the rotor shaft during assembly, thereby improving assembly efficiency and accuracy.

[0020] The servo drive mechanism includes a pressure cylinder servo motor 1, a reducer, a servo electric cylinder 3, and an operation control panel 4. The function of the servo drive mechanism is to apply pressure to the moving end, thereby achieving an interference fit connection between the rotor shaft and the rotor bearing.

[0021] In this embodiment, as Figure 1 As shown, the fixing platform is located on one side of the mounting platform, specifically including a fixing frame and a first pressure sleeve 7 mounted on the fixing frame. The first pressure sleeve 7 has an opening slot through which the rotor shaft is mounted. The first pressure sleeve 7 can be configured with a suitable pressure sleeve structure according to the size of the rotor shaft.

[0022] In this embodiment, as Figure 1 As shown, the centering lifting platform includes a V-shaped fixture 6, a horizontal guide rail 8, a lifting platform 9, and a lifting servo motor 10. The V-shaped fixture 6 is mounted on the horizontal guide rail 8 and can move horizontally on the horizontal guide rail 8; the lifting platform 9 is installed below the horizontal guide rail 8, and the lifting servo motor 10 is installed below the lifting platform 9. The lifting servo motor 10 can drive the lifting platform 9 to rise and fall, thereby ensuring that the rotor bearing and the rotor shaft are concentric.

[0023] In this embodiment, in order to ensure that the rotor remains horizontal during the assembly process, the rotor is horizontally fixedly mounted on the V-shaped tooling 6, and the V-shaped tooling 6 has a horizontal self-centering function, which can always maintain horizontal centering, thereby ensuring that the rotor shaft is accurately and correctly connected to the bearing inside the rotor with an interference fit.

[0024] In this embodiment, as Figure 1 As shown, the operation control panel 4 is connected to the pressure cylinder servo motor 1, and the pressure cylinder servo motor 1 is connected to the servo electric cylinder 3 through the reducer 2. The pressure parameters are set through the operation control panel 4, so that the pressure of the pressure cylinder servo motor 1 can be adjusted to adjust the pressure of the servo electric cylinder 3, thereby adapting to rotor bearings of different specifications, ensuring the safety and stability of assembly, and improving the product yield.

[0025] In this embodiment, as Figure 1As shown, the propulsion section at the front end of the servo electric cylinder 3 is equipped with a second pressure sleeve 5, which can push the bearing inside the rotor to engage with the rotor shaft. Similarly, the second pressure sleeve 5 can also be selected with a suitable pressure sleeve structure according to the size of the rotor shaft.

[0026] In order to ensure a certain degree of support for the propulsion part at the front end of the servo electric cylinder 3, and to ensure the stability of the propulsion process, a guide rail 11 is also connected below the propulsion part at the front end of the servo electric cylinder 3 via a support bar.

[0027] In the specific operation of the press device of this utility model, the rotor shaft is first fixed on the first pressure sleeve, and then the rotor is fixed on the V-shaped tooling. The height of the rotor is adjusted to be concentric with the rotor shaft. The pressure parameters are set through the operation control panel 4, and the servo electric cylinder 3 of the equipment is started to push the rotor closer to the rotor shaft, thereby pressing the end of the rotor shaft into the bearing inside the rotor to achieve an interference fit connection. Finally, the servo electric cylinder 3 is withdrawn.

[0028] The motor bearing servo press device of this utility model can adjust the installation pressure according to the rotor bearings of different specifications, thereby avoiding damage to the rotor bearings or rotor shafts and resulting in product defects.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
