Problems solved by technology

[0003] When the existing bearing is installed into the component, because the bearing and the hole on the component are interference fit, it needs to be pressed in by external force. Usually, a press is used, because it is an interference fit, so when it is assembled to the contact In the process, it is necessary to ensure its coaxiality. In the absence of good positioning to ensure its coaxiality, the axis of the bearing and the axis of the mounting hole have deviations, so that the bearing overlaps more with the surface of the part to be installed. , which is much larger than the limit value brought by the tolerance of interference fit, so when assembling, the overlapping area will be stressed first, which will cause the deformation of the bearing or the part to be installed in this area

Embodiment 1

[0030] see Figure 1-7 , the present invention provides a technical solution: a press for bearing installation, including a press base 1, and also includes:

[0031] The lower pressure ring 2 installed on the upper pressure plate of the press base 1;

[0032] The base plate 3 installed on the lower platen, the base plate 3 is installed on the lower platen by screws or bolts or other detachable installation methods, the base plate 3 is slidably connected with the base 4, the detachable mode is convenient for replacing the base plate 3, Because the installation of different bearings requires holes of different sizes to be set at the bottom, the base 4 is in the shape of a stepped shaft, and the diameter of the top is larger than the inner diameter of the hole where the bearing is installed on the part to be installed, and the press base 1 is also provided with Several nitrogen gas springs 5 ​​for supporting the base 4, the base 4 is provided with a locator 6 for positioning the...

Embodiment 2

[0039] refer to Figure 4 with Figure 5 Embodiment 2 is described. This embodiment is a further description of Embodiment 1. In order to keep the bearing treasure flat when the lower pressure ring 2 first comes into contact with the bearing, the positioning ring 14 is elastically rotatably connected with a number of Make it keep the support plate 21 flat before positioning, the elastic rotation connection is that the support plate 21 is rotatably connected on the positioning ring 14, and an elastic structural member, i.e. a clockwork spring or torsion spring, etc. is arranged on its rotating shaft, so that there is A certain thrust can hold the bearing and keep it stable, and when it is pressed down, it can rotate under the action of the thrust, so as not to hinder the positioning of the bearing by the positioning ring 14. The support plate 21 is preferably provided with 3 or 4 sets. Keep it flat before positioning.

Embodiment 3

[0041] refer to Figure 8 The second embodiment is described. The difference between this embodiment and the first embodiment is that the positioning end of the positioning rod 11 is inlaid with a positioning bead 22. The first embodiment uses a positioning wheel 20 for positioning. The contact is a line contact, so its positioning is better than that of the positioning bead 22, but because in the subsequent process, the positioning member 6 needs to be separated from the mounting hole, that is, the positioning wheel 22 will move along its axial direction, so this method has greater friction. And adopt inlaid positioning bead 22, can all replace sliding by rolling in any direction, thereby be convenient to reduce friction, can reduce the wear and tear in the working process of the whole, can prolong the service life.

Abstract

The invention discloses a press machine for bearing installation. The press machine comprises a press machine base body, and further comprises a lower pressing ring installed on an upper pressing plate of the press machine base body and a bottom plate installed on the lower pressing plate. A base is connected to the bottom plate in a sliding mode. A plurality of nitrogen springs used for supporting the base are further arranged in the press machine base body. A positioning piece used for positioning a bearing and a to-be-installed piece is arranged on the base. According to the press machine for bearing installation, the positioning piece is arranged on a traditional press machine, the bearing is positioned by the positioning piece through a positioning ring and balls, when the press machine works, the axis of the bearing is automatically aligned with the axis of the to-be-installed piece through a positioning rod on a positioning cylinder before the bearing is not in contact with the to-be-installed piece, and then the bearing is installed; and the axis of the bearing and the axis of the to-be-installed piece are automatically adjusted for installation, so that the problem of abrasion caused by assembling can be reduced, and the percent of pass of products is improved.

Description

technical field [0001] The invention relates to the technical field of presses, in particular to a press used for bearing installation. Background technique [0002] Bearing is an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. [0003] When the existing bearing is installed into the component, because the bearing and the hole on the component are interference fit, it needs to be pressed in by external force, and a press is usually used, because it is an interference fit, so when it is assembled to the contact In the process, it is necessary to ensure its coaxiality. In the absence of good positioning to ensure its coaxiality, the axis of the bearing and the axis of the mounting hole have deviations, so that the bearing overlaps more with the surface of the part to be installed. , which is much larger than the limit value ...
