Description

Technical field:

[0001] The utility model relates to the technical field related to wheel hub processing equipment, and more specifically to a wheel hub insert installation tool. Background technology:

[0002] With the rapid development of new energy vehicles and continuous breakthroughs in technological innovation, the application of wheel hub inserts is becoming more mature, and more and more wheels will use inserts.

[0003] Currently, when inserts are installed manually, the wheel hub is placed directly on a workbench. One hand needs to set the wheel hub in a vertical state and hold the wheel hub firmly to make it difficult to move, and install the insert on the wheel hub. The other hand holds a pneumatic tool for installation. The labor intensity is high and the efficiency is low. In addition, moving the wheel hub requires two hands to operate and move, which is very troublesome.

[0004] Moreover, when operating on a workbench, the wheel hub is easily rubbed against the surface of the workbench when placed, causing the paint on the surface to wear and affect its quality. Utility model content:

[0005] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a wheel hub insert installation tool, which can place the wheel hub obliquely in the air so that its surface is not easily rubbed or broken by other objects, etc., which is convenient for installing the insert and is convenient for manual support and rotation, so that the position where the insert is needed can be in a convenient operating position, greatly reducing the amount of manual labor.
