[0006] As a further improvement, the driving assembly includes a driving cylinder, a mounting seat and a top block. The driving cylinder is installed under the base through the mounting seat, and the top block is installed on the output end of the driving cylinder. The output end of the driving cylinder can move through the base to contact the movable top core.

[0007] Furthermore, the center of the movable ejector core and the center of the upper ejector rod are located on the same axis.

[0008] Furthermore, an annular groove is provided on the top surface of the lower fixing plate, and a plurality of leveling steel balls are embedded in the annular groove.

[0009] Furthermore, support plates are provided on both sides above the base, and the lower fixing plate is detachably connected to the support plates via connecting screws.

[0010] Furthermore, a stepped hole is provided in the middle of the lower fixed plate, the movable top core is installed in the stepped hole, and a retaining spring is provided on the stepped hole to prevent the movable top core from falling.

[0011] Furthermore, a connecting plate is provided on the upper push rod, and the connecting plate is connected to the slider of the hydraulic press through connecting bolts.

[0012] Beneficial effects

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. By setting a high-strength magnetic ring on the upper ejector, the steel sleeve can be quickly installed on the upper ejector. Then, the movable ejector core of the lower fixed plate is used to quickly position the Y-shaped chain link. Finally, the hydraulic press is used to drive the upper ejector downward to quickly press the steel sleeve into the mounting hole of the Y-shaped chain link. No manual hammering or installation is required, which effectively improves production efficiency.

[0015] 2. By setting up a driving component, the output end of the driving cylinder pushes the ejector block, and the ejector block pushes the movable ejector core. The movable ejector core moves upward in the stepped hole and limits its position. Then, the mounting hole of the Y-shaped chain link is placed on the protruding part of the movable ejector core, which plays a positioning role. On the one hand, it ensures that the steel sleeve can be smoothly pressed into the mounting hole. On the other hand, it ensures the verticality of the mounting hole, effectively improving the press-fitting quality of the product. BRIEF DESCRIPTION OF THE DRAWINGS
