With reference to fig. 5 to 7, the flexible indenter 6 comprises: an error absorbing module and a guide assembly 65 disposed at the bottom of the error absorbing module. Preferably, the error absorption module includes: the pressure welding device comprises a pressure welding plate 61 connected with a guide assembly 65, a lower floating plate 62 arranged on the upper portion of the pressure welding plate 61 and connected with the pressure welding plate 61, an upper floating plate 63 positioned above the lower floating plate 62, an angle adjusting plate 64 arranged between the upper floating plate 63 and the lower floating plate 62, and an elastic reset mechanism respectively connected with the lower floating plate 62 and the upper floating plate 63, wherein a spherical bulge 621 is arranged in the middle of the top of the lower floating plate 62, a spherical groove corresponding to the spherical bulge 621 is arranged on the bottom surface of the angle adjusting plate 64, namely, the upper floating plate 63 is connected with the lower floating plate 62 through a spherical surface, and the lower floating plate 62 and the pressure welding plate 61 can rotate relative to the upper floating plate 63 so as to realize error absorption. Specifically, the upper floating plate 63 is connected to the quick release mechanism 5 through a connecting bolt 66, and provides a support and installation space for other components, and the guide assembly 65 is used for aligning with the crimping platform 14, deflecting when an angular displacement error exists between the crimping platform 14, and transmitting the angular displacement error to the elastic reset mechanism through the crimping plate 61. The elastic reset mechanism receives the angle displacement error of the crimping plate 61 through the lower floating plate 62, and drives the crimping plate 61 and the guide assembly 65 to reset through the lower floating plate 62 after the guide assembly 65 is separated from the crimping platform 14.

It should be noted that the guide assembly 65 is a guide pin, and the crimping platform 14 is provided with a guide hole corresponding to the guide pin. When the flexible crimping apparatus performs a press-in operation, a guide pin needs to be inserted into the guide hole to achieve accurate alignment. Because the crimping platform 14 has a problem of installation error, in actual operation, the guide pin and the guide hole are not in a completely aligned state, therefore, in this embodiment, it is preferable to set the bottom of the guide pin to be an inverted cone frustum structure, and the diameter of the bottom surface of the inverted cone frustum structure is smaller than the diameter of the top surface of the inverted cone frustum, that is, the guide pin, so that the guide pin can smoothly enter the guide hole within a certain error range, thereby eliminating offset error and realizing accurate alignment. Of course, when the bottommost end of the guide pin, namely the inverted cone frustum structure, enters the guide hole, the guide pin can deviate to one side of the guide hole; then, the guide pin is acted and guided by the inclined surface of the inverted cone frustum structure, and gradually moves towards the center of the guide hole, so that accurate alignment is realized. Because the guide assembly 65 is fixedly connected with the crimping plate 61, and the crimping plate 61 is connected to the elastic reset mechanism through the lower floating plate 62, the lower floating plate 62 moves along with the guide pin in the alignment process of the guide pin and the guide hole, so that the offset error adjustment of the flexible pressure head 6 and the crimping platform 14 can be realized while the guide pin is aligned with the guide hole.
It will be apparent to those skilled in the art that various changes and modifications may be made in the invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
