Description

Bearing press-in-place checking mechanism and use method

Technical Field

The invention relates to the field of machining, in particular to a bearing press-in-place checking mechanism and a using method thereof.

Background

The common bearing is installed on the workpiece by knocking or pressing in, if the bearing is not installed in place, the workpiece is easy to skew and cannot normally run, and the bearing is seriously easy to break. However, it is difficult to verify whether the bearing is in place or not, and whether the lower end of the bearing is already in contact with the workpiece, so that it is urgent to find a bearing press-in-place inspection mechanism which is convenient to operate.

Disclosure of Invention

The invention aims to solve the technical problem of providing the bearing press-in-place checking mechanism, which has a simple structure, is convenient to use, can accurately judge whether the bearing is installed in place, and can be further consolidated to ensure that the bearing is installed in place.

In order to solve the above problems, the first technical solution provided by the present invention is: the bearing press-in-place checking mechanism comprises a body part and an extending part arranged at one end of the body part, wherein the extending part is matched with the bearing inner ring, and the extending part comprises a lower end face matched with the workpiece.

Further, the bearing press-in-place checking mechanism also comprises a cavity arranged in the bearing press-in-place checking mechanism.

Further, the extension has the same height as the bearing.

Further, the diameter of the body part is larger than that of the inner ring of the bearing, a flange is formed at the joint of the body part and the extension part, and the flange is matched with the upper end face of the bearing.

Further, the bearing press-in-place checking mechanism further comprises a knocking part arranged at the other end of the body part.

In order to solve the above problems, a second technical solution provided by the present invention is: the application method of the bearing press-in-place checking mechanism comprises the steps of knocking the bearing press-in-place checking mechanism, enabling the extension part to be embedded into the inner ring of the bearing in a pressing mode, enabling the lower end face to act with the workpiece and sounding, and judging whether the bearing is installed in place or not.

Further, knocking the knocking part of the bearing pressing-in-place checking mechanism to generate a smoldering clatter, so that the bearing is installed in place; and (3) making loud clattering sounds, and the bearing is not installed in place.

The invention has the beneficial effects that:

the invention provides a bearing press-in-place checking mechanism, which has the following advantages compared with the prior art:

the bearing press-in-place checking mechanism comprises a body part and an extending part arranged at one end of the body part, the extending part is matched with the bearing inner ring, the extending part comprises a lower end face matched with the workpiece, the bearing press-in-place checking mechanism is knocked, the extending part is embedded into the bearing inner ring in a pressing mode, the lower end face acts on the workpiece and sounds to judge whether the bearing is mounted in place, the bearing press-in-place checking mechanism is simple in structure and high in universality, and according to the principle that the bearing is necessarily contacted with the workpiece when the bearing inner ring is contacted, whether the bearing is pressed in place can be judged through simple press-in action and listening, meanwhile, the bearing can be pressed down further through the press-in action to further ensure that the bearing is mounted in place, so that the bearing press-in-place checking mechanism has a checking function and a consolidating function.

Drawings

FIG. 1 is a cross-sectional view of a bearing press-in-place inspection mechanism in an embodiment of the present invention;

fig. 2 is a diagram showing an operation state of the bearing press-in-place checking mechanism in the embodiment of the present invention.

The specific embodiment is as follows:

examples: the preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making clear and defining the scope of the present invention.

As shown in fig. 1, a bearing press-in-place inspection mechanism 100 is provided, and the bearing press-in-place inspection mechanism 100 includes a main body 1, an extension 2 provided at one end of the main body 1, and a striking portion 3 provided at the other end of the main body 1, wherein the extension 2 is engaged with an inner ring of a bearing 30, and the extension 2 includes a lower end surface 21 engaged with a workpiece 40, and in use, whether the bearing 30 is mounted in place is determined by whether the lower end surface 21 can strike a contact surface of the workpiece 40.

Specifically, the extension 2 has a columnar structure, and in use, it is inserted into the inner race of the bearing and fitted to the inner race of the bearing 30. Since the extension 2 has the same height as the bearing 30, the extension 2 is entirely fitted into the inner race of the bearing 30 when in use. The diameter of the body part 1 is larger than that of the inner ring of the bearing 30, a flange 11 is formed at the joint of the body part 1 and the extension part 2, and the flange 11 is matched with the upper end face of the bearing 30. In use, flange 11 is in a tight fit with bearing 30, providing a downward pressure on bearing 30, forcing bearing 30 further into place.

Since the bearing and the mounting surface of the workpiece 40 are inside, it cannot be checked by naked eyes or other equipment whether the bearing is in place or not, and it is judged by hearing, so that the bearing is pressed into the place and the cavity 4 is arranged inside the checking mechanism 100. By the impact sound specific to the hollow structural object, we determine whether the bearing 30 is mounted in place. From the above description of the bearing press-in-place inspection mechanism 100, it can be known that, when the bearing 30 is mounted in place, the knocking part 2 of the bearing press-in-place inspection mechanism 100 is knocked to generate a clunking "clattering" sound; when the bearing 30 is not mounted in place, the knocking part 2 of the bearing press-in-place inspection mechanism 100 is knocked, and a loud "clattering" sound is generated.

When we need to press-in-place check the already mounted bearing 30, we insert the extension 2 of the bearing press-in-place check mechanism 100 into the inner race of the bearing 30 and ensure that the flange 11 and the end face of the bearing 30 abut, as shown in fig. 2. Then, a knocking object such as a hammer is adopted to knock the knocking part 2, when the clatter sound is heard, the bearing 30 is already installed in place, and the next working procedure can be carried out; when hearing loud "clatter" sound, then bearing 30 is not still in place, and at this moment we strike knocking part 2 again, until hearing the clunked "clatter" sound, then press-in to the consolidation of inspection mechanism 100 through this bearing, bearing 30 has already been installed in place, can get into next process.

While the foregoing is directed to the preferred embodiments of the present invention, it will be appreciated by those skilled in the art that changes and modifications may be made without departing from the principles of the invention, such changes and modifications are also intended to be within the scope of the invention.
