2. A method of gluing an automatic gluing device for gluing the joint surfaces of the axle stub and the rear cap according to claim 1, characterized in that it comprises the following steps:
firstly, adjusting the extending length of an adjustable clamping jaw (6032) according to the aperture size of the axle housing, and particularly being suitable for reading the aperture size of the axle housing from a graduated scale (6033) on the side surface of the clamping jaw;
then, inserting a secondary tool (703) into a threaded hole of the axle housing through an axle housing positioning pin (7032) and placing the secondary tool on the axle housing;
then, controlling the suspension device (1) to lower the height of the gluing device, in the process, sleeving the insert plate (702) outside the insert plate positioning pin (7033), and finally clamping the clamping jaws (6032) on the axle housing joint surface so as to determine the gluing starting position;
then, the pneumatic chuck (602) is inflated and tightened to finish the centering and fixing work of the gluing device;
then, removing the secondary tooling (703) from the axle housing;
then, starting an automatic control program, enabling the gluing head to descend under the action of a vertical lifting mechanism (4), completing gluing operation under the matched driving of a first servo motor (301) and a second servo motor (501), and after gluing is completed, enabling the gluing head to ascend under the action of the vertical lifting mechanism (4);
and finally, controlling the suspension device (1) to enable the height of the gluing device to rise, and thus, completing a complete gluing process.
