Description

Technical Field

[0001] The utility model relates to the field of press-fitting of motor components, in particular to a yoke press-fitting device applied to an assembly line body. Background Art

[0002] When assembling the motor, the yoke needs to be press-fitted. Currently, it is press-fitted by an independent device. For example, a Chinese utility model patent with authorization announcement number CN105575647B and authorization announcement date 2017.09.22 discloses a device for continuously pressing the electromagnet yoke onto a base plate. Another Chinese utility model patent published on 2023.09.22 and with publication number CN 116787110 A discloses an automatic press-fitting device for a rotor shaft and a yoke based on intelligent manufacturing. Both are performed by independent devices, which cannot be embedded in the existing motor assembly line. The two components to be press-fitted need to be transported to an external press-fitting device by a robot, a crane or manually before they can be assembled. This results in low working efficiency of the original motor assembly line. Utility Model Content

[0003] In order to overcome the above-mentioned shortcomings, the purpose of the utility model is to provide a yoke pressing device applied to an assembly line body, which can be embedded in the existing motor assembly line body and improve the yoke pressing efficiency.

[0005] The beneficial effect of the yoke pressing device applied to the assembly line body of the utility model is that the hollow base at the bottom of the press is used to embed the existing assembly line body of the motor. There is no need to move the yoke to other devices for pressing, and the yoke can be directly pressed on the assembly line body, which improves the overall assembly efficiency of the motor. When pressing the yoke, the driving cylinder drives the lifting platform to be higher than the assembly line body to protect the existing assembly line body, so as to avoid the problem that the existing assembly line body will be damaged if the yoke is directly pressed on the assembly line body due to the large mass of the yoke.

The passive transmission member and the active transmission member are both provided with a bar-shaped toothed structure, and the translation of the active transmission member is utilized to force the passive transmission member to drive the lifting platform to rise and fall, so as to realize that the lifting platform is higher or lower than the assembly line. The structure is simple, compact, and can be assembled in a relatively narrow installation space, which is conducive to embedding into the existing assembly line.

[0007] Preferably, at least two passive transmission members are provided, which are arranged in parallel at the bottom of the lifting platform; at least two active transmission members are correspondingly provided, and the same end is fixed to the connecting plate, and the telescopic shaft of the driving cylinder is fixed to the connecting plate.

[0009] Preferably, the support plate is provided with a plurality of clearance grooves or clearance holes, the number of which is the same as the number of guide posts; the bottom of the guide post can reach the clearance grooves or pass through the clearance holes. The provision of the clearance grooves or clearance holes provides sufficient space for the guide post to descend, making the overall structure compact.

[0010] Preferably, the size of the clearance groove or the clearance hole is larger than the size of the guide sleeve. The bottom of the guide sleeve can also be embedded in the clearance groove or the clearance hole, providing enough installation space for the lifting platform as much as possible in a limited space.
