[0012] Figure 2 It is a structural schematic diagram of the edge expansion tooling of the present utility model. DETAILED DESCRIPTION
[0013] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.
[0014] like Figure 1 、 Figure 2 The automatic rebound and reset edge expansion mechanism for a connector shown includes a riveting machine and an edge expansion tooling arranged on the riveting machine;
[0015] Specifically, the riveting machine includes a frame 1 and a rivet head 2, which is fastened by screws and can be raised and lowered;
[0016] Specifically, the edge expansion tooling includes a main body 7, an outer cover 3, an expansion head 5, a pin 6 and a spring 8. The main body 7 is fixed to the riveting machine through a base 9. The top of the main body 7 is integrally formed with a positioning seat that can be sleeved with a connector. The positioning seat includes a first positioning seat, a second positioning seat, and a third positioning seat that are coaxially arranged from top to bottom. The diameters of the first positioning seat, the second positioning seat, and the third positioning seat increase in sequence to form a multi-step structure that can accurately position the plug-in connector. The expansion head 5 is a cylindrical structure. The expansion head 5 is coaxially sleeved outside the positioning seat and fixed to the positioning seat. The top of the main body 7 has a step that can support the expansion head 5. A lock is provided on one side of the main body 7. Tightening groove 4-1, the expanding head 5 is detachably connected to the locking groove 4-1 by a screw 4, the outer diameter of the expanding head 5 is the same as the outer diameter of the main body 7, and there is a gap between the inner cavity of the expanding head 5 and the positioning seat. The outer wall of the top of the expanding head 5 has a conical guide groove with a diameter gradually increasing from top to bottom. The outer cover 3 is coaxially sleeved on the outside of the expanding head 5, and the bottom end of the outer cover 3 is elastically connected to the main body 7 through a spring 8. Guide grooves 6-1 are symmetrically provided on both sides of the outer cover 3, and the pin 6 is fixed in the main body 7 and parallel to the horizontal plane. The two ends of the pin 6 respectively pass through both sides of the main body 7 and extend into the guide groove 6-1. The outer cover 3 can be lifted and lowered along the expanding head 5 and the outer wall of the main body 7 and the lifting range is limited by the pin 6.
