Closing-in device of joint bearing with spherical surface

Abstract

The invention discloses a closing-in device of a joint bearing with a spherical surface, which comprises a pedestal comprising a base of a rectangular frame groove and a pressing plate which is fixedly connected to the upper end of the base of the rectangular frame groove, wherein the upper end and the lower end of the pedestal are provided with a closing-in type face pressing plate and double-acting rollers, which act on a closing-in face of the bearing in opposite directions, the closing-in type face pressing plate is provided with a groove of which the shape is consistent with the shape of the closing-in face of the bearing, the closing-in face of the bearing is jointed by the closing-in type face pressing plate through a rotary pressing bolt connected to the closing-in type face pressing plate from top to bottom, both ends of the closing-in face of the bearing are supported by the double-acting rollers through an end face bearing which is fixedly connected to a bottom plate of the pedestal from bottom to top, and a manual rotating shaft passes through center holes of the rotary pressing bolt, the closing-in type face pressing plate and the joint bearing with the spherical surface and is fixedly connected to an end face between the rollers at both sides. In the closing-in device of the joint bearing with the spherical surface, which is disclosed by the invention, rolled bearing closing in is carried out on a closing-in part of the bearing by utilizing force generated by the rotary bolt. The closing-in device of the joint bearing with the spherical surface is simple and easy to operate and is convenient and quick, and the closing-in positioning is accurate. The closing-in depth can be randomly regulated, and the problem that bearing closing in needs to be manually carried out at the assembly stage of the closing-in part of the bearing is solved.

Description

technical field [0001] The invention relates to a tool for closing a bearing. Background technique [0002] In general, the bearing closure is to first make the bearing hole on the part, and then install the bearing and the closure on the machine tool. The bearing hole that needs to be closed for this part has a relatively high relative position requirement with other parts, and the final hole needs to be made after assembly, and the bearing is installed and closed during the assembly process. In this way, due to the large size and irregular shape of the assembly, the bearing cannot be closed on the machine tool, and a special tool needs to be designed to close it. The difficulty is that the bearing is a spherical joint bearing, and the inner body can rotate universally, so it is not easy to locate; secondly, the bearing that is generally closed on the machine tool, such as Figure 5 As shown, the closing depth is guaranteed by the machine tool, and the rolling closing is c...

AI Technical Summary

Problems solved by technology

In this way, due to the large volume and irregular shape of the assembly, it is impossible to close the bearing on the machine tool, and it is necessary to design a special tool to close it

The difficulty is that the bearing is a spherical joint bearing, and the inner body can rotate universally, so it is not easy to locate; secondly, the bearing that is generally closed on the machine tool, such as Figure 5 As shown, the depth of the seam is guaranteed by the machine tool, and the rollers are used to roll the seam at both ends of the bearing

However, in the assembly stage, it is generally impossible to close the bearing on the machine tool, and a manual bearing closer is needed to ensure the bearing closes
