technical field

The utility model relates to an auxiliary tool, in particular to a device for quickly picking up a vertical motor thrust head.

Background technique

The thrust head is one of the important parts of the motor, and it is generally directly sleeved on the motor shaft. For a long time, in order to improve the stability of the motor operation and reduce vibration, the thrust head and the motor shaft are assembled with interference. There are some advantages, but at the same time, it will bring the problem of extremely inconvenient installation and removal of the thrust head. Previously, the thrust head was disassembled and assembled manually by using a wrench with a screw and a nut, which was time-consuming and labor-intensive. It is more difficult to disassemble and assemble. Now many manufacturers use jacks with screws and nuts to disassemble and assemble. However, in some cases, the installation or placement of the jack itself lacks space, which is extremely unstable, making the force inconvenient, and the disassembly effect cannot be guaranteed. , for this purpose, we propose a device for quickly assembling the thrust head of a vertical motor.

The two jacks are placed on the cap body, and the upper end can be pushed to the connecting plate. The top of the motor shaft is machined with a plurality of blind screw holes, and a plurality of screws are screwed through the connecting plate. It is then screwed and installed in multiple blind screw holes. The disassembly assembly includes two jacks, multiple studs and multiple nuts 1. The second jack is placed on the top of the motor shaft and can be pushed to the connecting plate, and the upper ends of the multiple studs are connected and connected. The lower end is connected to the thrust head through the cap body, and the plurality of nuts are screwed on the upper ends of the plurality of studs and are located above the connecting plate.

In order to increase the space for placing the jack, the cap body is a round top hat-like structure, and includes a cap top and a brim. The inner diameter of the cap top corresponds to the outer diameter of the thrust head, and both sides of the brim are trimmed, and both sides are at the inner edge of the trimmed edge. There are annular strapping belts extending outward and facing each other, the strapping belts on both sides are provided with fastening heads perpendicular to them at the ends, the fastening heads are provided with holes, and the holes on both sides are matched with bolts, Screw in the second nut.

In order to realize the universality of the connecting plate during installation and disassembly and in order to reduce the specification of the second jack, the connecting plate is an inverted step-shaped circular plate structure. A plurality of through holes are provided.

The utility model adopts the above-mentioned structure and has the following advantages:

1. The body of the cap is added, leaving a space for placing the jack, so that the jack can be firmly placed on the body of the cap, so that the jack can be lifted smoothly to ensure that the installation of the thrust head meets the accuracy requirements, and the overall structure is simple, efficient and convenient;

2. Put the cap body on the thrust head so that its inner diameter corresponds to the outer diameter of the thrust head, and use the thrust head itself to give the cap body a support, which not only increases the space for the placement of the jack, but also does not need to change the motor shaft and the thrust head itself. The structural features of the jack are combined with a pair of oppositely arranged strapping straps on both sides to adjust and clamp to ensure that the cap body and the thrust head form an inseparable whole, so that the jack has a stable focus point and ensures that the jack is stable and reliable.
