Disclosure of Invention
The utility model aims to provide a bearing installation auxiliary device which is used for solving the problem of low installation efficiency of the existing bearing and rotating shaft installation mode.
In order to achieve the above purpose, the basic scheme provided by the utility model is as follows: the hydraulic oil cylinder is arranged at the top end of the stand column, and a steel plate is connected to the telescopic end of the hydraulic oil cylinder.
The principle and the beneficial effects of the utility model are as follows: when the bearing is replaced, the bearing is placed on the support column, then a worker places the rotating shaft at the center of the bearing and holds the rotating shaft by hand, the hydraulic oil cylinder is started, the hydraulic oil cylinder drives the steel plate to move downwards until the steel plate contacts the rotating shaft, the rotating shaft is extruded downwards, when the rotating shaft is extruded into the bearing, the rotating shaft is in interference fit with the bearing, then the worker loosens the rotating shaft, the steel plate continues to move downwards to extrude the rotating shaft, the rotating shaft stretches into the bearing, and the installation of the bearing and the rotating shaft is completed. Compared with the existing bearing installation mode, the device drives the steel plate to move downwards through the hydraulic oil cylinder, the rotating shaft and the bearing are installed in an extrusion mode, when the installation is carried out, a worker only needs to hold the rotating shaft at the beginning, when the rotating shaft enters the bearing to generate interference fit, the rotating shaft can be loosened, and then the rotating shaft is continuously installed in the bearing by using a machine, so that the installation efficiency is improved.
And in the second scheme, the support columns are preferably arranged in the base, the four support columns are connected to the base in pairs, and when the bearing is installed, the support columns are arranged in a manner that better supports the bearing, so that the bearing cannot deviate or turn due to uneven stress when the rotating shaft is installed.
The third scheme is that the second scheme is preferable, each support column is connected with a screw in a rotating mode, each screw is connected with a fixing plate in a threaded mode, each fixing plate is fixedly connected to the top end of the base, and the fixing plates and the screws can be used for adjusting and fixing the support column.
According to the scheme IV, the L-shaped hooks and the storage grooves are respectively arranged on the upright posts, so that the common tools can be hung on the L-shaped hooks and the storage grooves, the time for taking and placing the tools by workers is saved, and the working efficiency is improved.
The fifth scheme is the third scheme, and a sliding groove is formed in the top end of the base right below each supporting column, the supporting columns are all connected in the sliding groove in a sliding mode, and the sliding grooves can drive the supporting columns to move and can be suitable for supporting bearings of different specifications.
The sixth scheme is the third scheme, and the screw is fixedly connected with a rotating hand wheel, and the arrangement of the rotating hand wheel enables workers to save more labor when rotating the screw.
