The structure can play an effective supporting role for the inner wall of the thin-wall steel sleeve 8 in the press fitting process through the arrangement of the guide post 4, and prevent the concave deformation of the thin-wall steel sleeve due to the press fitting force; the sliding fit of the teeth 41 and the tooth grooves 22 effectively guarantees the reliability of the press-fitting process, the tooth grooves 22 of the press plate 2 can apply press-fitting force on the end face of the thin-wall steel sleeve 8, the thin-wall steel sleeve 8 is also guaranteed not to be plugged into the fit clearance between the guide post 4 and the press plate 2, and the teeth 41 of the guide post 4 can well support the inner wall of the thin-wall steel sleeve 8, so that the steel sleeve is guaranteed not to be recessed inwards.

The guide plate 3 can effectively increase the guide area and ensure that the process that the guide post 4 retracts into the sliding cavity 11 cannot generate deflection and blockage problems.

In one embodiment, the guide plate 3 and the top of the sliding chamber 11 are connected by a return spring 5, so that the guide plate 3 is restored to the initial position by the return spring 5 after the press-fitting is completed.

In one embodiment, the guide plate 3 is provided with a first positioning protrusion 31, the top of the sliding cavity 11 is provided with a second positioning protrusion 111, and one end of the return spring 5 is sleeved on the first positioning protrusion 31, and the other end is sleeved on the second positioning protrusion 111.

In one embodiment, the guide post 4 is provided with a plurality of teeth 41 in the circumferential direction, and the teeth 41 and the tooth spaces 22 are in one-to-one correspondence, so that each tooth 41 corresponds to one tooth space 22, and the motion stability of the guide post 4 is ensured.

In one embodiment, the plurality of teeth 41 of the guide post 4 are circumferentially distributed uniformly to ensure the uniformity of the force.

In one embodiment, the teeth 41 are arc-shaped teeth, and the tooth socket 22 is adapted to the tooth 1. The teeth 41 with the shape are evenly stressed, and the reliability and the centering performance of the guide post 4 can be better ensured.

It is to be understood that the teeth 41 are not limited to the above-described shape, and other shapes of teeth may be employed.

In one embodiment, the press-fitting body 1 and the pressure plate 2 are connected by a first screw 6.

In one embodiment, the platen 2 is circular.

Referring to fig. 3, the embodiment further discloses a method for press-fitting a thin-wall steel sleeve by using the press-fitting device for a thin-wall steel sleeve, which includes the following steps:

1) sleeving a thin-wall steel sleeve 8 on the guide post 4, and placing the part 9 to be pressed below the guide post 4, so that the axes of the guide post 4 and the part 9 to be pressed are overlapped;

2) the press is used for driving the press-mounting main body 1 to descend, the press-mounting main body 1 drives the thin-wall steel sleeve 8 to descend until the pressing plate 2 presses and mounts the thin-wall steel sleeve 8 on the outer wall of the part 9 to be press-mounted, and the bottom of the guide column 4 is contacted with the top of the part 8 to be press-mounted;

the pressing main body 1 is driven to continuously descend, the depth of the thin-wall steel sleeve 8 pressed into the part 8 to be pressed is gradually increased, in the process, the guide post 4 slides upwards relative to the pressing plate 2 due to the jacking of the part 8 to be pressed, namely the tooth 41 slides upwards along the tooth groove 22, the guide post 4 moves to drive the guide plate 3 to move upwards along the sliding cavity 11 until the pressing plate 2 completely presses the thin-wall steel sleeve 8 on the outer wall of the part 9 to be pressed, the part 9 to be pressed and the thin-wall steel sleeve 8 form a finished product, and the pressing main body 1 stops descending;

it can be understood that during the process of moving the guide post 4 upwards, the guide post 4 enters the sliding cavity 11 and slides in the sliding cavity 11 together with the guide plate 3.

3) The press-fitting main body 1 is driven to ascend until the guide post 4 is separated from the press-fitting finished product. After the separation, the guide post 4 will return to the initial position under the action of the return spring 5.

The press fitting device of the thin-wall steel sleeve can effectively ensure that the thin-wall steel sleeve 8 is supported inside in the whole press fitting process, and can also effectively ensure that the thin-wall steel sleeve 8 cannot be pressed into a sliding fit gap between the guide column 4 and the pressing plate 2, so that the press fitting device can realize one-time press fitting without the phenomenon of collapse and deformation, shortens the press fitting time and improves the assembly efficiency.
