Background
The end connector is an important part of a crawler type vehicle action system and plays an important role in the overall maneuvering performance of the vehicle. When the inner arc surface of the end coupler is quenched, the stability and accuracy of the positioning tool play a decisive role in quenching hardness. If the positioning tool is unstable, the hardness of the inner arc surface of the end coupling device is lower than that of a matched part in the heating process, so that the abrasion of the end coupling device is accelerated, and the performance of the whole vehicle is influenced. The prior intermediate frequency quenching bracket is positioned by a single hole and side teeth, and because the size of the upper plane and the lower plane of the forged part is wide, the quenching water is easy to interfere after the part is heated and the hardness and the area after quenching are affected, the intermediate frequency quenching bracket needs to be improved to be positioned by the two side teeth for plug-in type up-down material taking.
