Description

Technical Field

[0001] The utility model relates to the field of automobile bearing installation, in particular to an automobile accessory bearing installation device. Background Art

[0002] Bearings are a very common part in mechanical equipment. During installation, in order to prevent them from falling off during later use, the bearings are installed with interference fit. Interference fit is generally achieved by hammering and heating the mounting ring surface with an acetylene spray gun to make it expand before installation. The former is only used for some equipment that does not require high precision, while the latter is suitable for most bearing installations. However, there is still the risk of excessively high bearing temperatures and safety hazards during the installation and heating process. Therefore, based on this technology, we designed an automotive parts bearing installation device. Utility Model Content

The driving wheel is connected to a servo motor, and the servo motor is mounted on the supporting plate.

[0009] A lifting handle is arranged on the connecting plate.

[0010] The beneficial effects of the utility model are:

[0011] When the bearing is at room temperature, place it in this equipment, insert the acetylene spray gun and rotate it back and forth to heat it. After completion, retract the spray gun, lift the equipment and put the bearing on the shaft. After limiting the position, pull out the equipment and the bearing can be safely installed.
