[0019] See also Figure 1-5The present embodiment is a riveting tool 2 for an overtravel pressing sleeve locating pin, comprising a base 26, a positioning sleeve plate 23, and an upper pressing plate 21. A spring 24 cavity is provided at the bottom of the positioning sleeve plate 23, a supporting spring 24 is installed in the spring 24 cavity, a fixing bolt 27 is installed in the supporting spring 24, the bottom end of the fixing bolt 27 is threadedly connected to the base 26, and the top of the fixing bolt 27 is slidably connected to the positioning sleeve plate 23. A positioning hole matching the overtravel pressing sleeve 3 is provided in the middle of the positioning sleeve plate 23, and the axis of the positioning hole is arranged in the horizontal direction. An upper riveting hole is provided above the positioning hole in the positioning sleeve plate 23, and a lower riveting hole is provided below the positioning hole. The upper riveting hole and the lower riveting hole are both connected with the positioning hole. An upper riveting head 22 is provided at the bottom of the upper pressing plate 21, and the upper riveting head 22 is inserted in the upper riveting hole. A lower riveting head 25 is provided at the top of the base 26, and the upper end of the lower riveting head 25 is inserted in the lower riveting hole.

[0020] Furthermore, the bottom end of the upper riveting head 22 and the top end of the lower riveting head 25 are both provided with sharp teeth, and the sharp teeth are used to press into the positioning pin 31 to deform the end of the positioning pin 31.

[0021] Furthermore, the upper riveting head 22 and the lower riveting head 25 are each provided with two sharp teeth, and the two sharp teeth correspond to two sides of the end surface of the positioning pin 31 respectively.

[0022] Furthermore, there are two spring cavities 24 symmetrically arranged on both sides of the positioning sleeve 23 , and a supporting spring 24 is installed in each spring cavity 24 .

[0023] See also Figure 1 Before riveting, the insulating pull rod is assembled and inserted into the tooling, and the positioning pin 31 of the overtravel sleeve 3 is positioned sideways in the positioning hole through the positioning sleeve 23. At this time, the spring 24 at the bottom of the positioning sleeve 23 is in a pop-up state, and the upper riveting head 22 and the lower riveting head 25 are both in a pre-riveting state and do not contact the parts of the insulating pull rod, so they do not affect the assembly of the insulating pull rod in and out of the positioning sleeve 23; after the insulating pull rod is inserted into the positioning hole of the positioning sleeve 23, it is positioned by clinging to one side of the positioning sleeve 23, that is, the distance from the side of the positioning sleeve 23 to the center of the riveting head is equal to the distance from the center of the positioning pin 31 to the baffle of the insulating pull rod, and the riveting action is performed after positioning.

[0024] See also Figure 2 and Figure 5 By operating the press machine 1 to apply downward pressure according to the set stroke, the sharp teeth of the upper riveting ram 22 and the lower riveting ram 25 are riveted to the upper and lower end surfaces of the locating pin 31, so that the two ends of the locating pin 31 are deformed and support the pin hole. The press machine 1 returns to its original position at the end of the stroke. Under the action of the spring 24, the locating sleeve 23 rebounds. At this time, the insulating pull rod can be pulled out of the tooling.
