Therefore, the escape position 511 of the quick release switching lever 51 can be moved into and out of the opening of the mounting groove, and the fixing position 512 cannot be moved into and out of the opening of the mounting groove. Therefore, the fixing portion 512 is used to enter the mounting groove after the quick release switch lever 51 is mounted, so as to avoid the quick release switch lever 51 from being separated from the quick release block 53.
Preferably, the elastic limiting component is used for performing position switching and limiting on the quick-release switching rod 51. Specifically, the elastic limiting assembly includes: the second spring 55, the first limit ring 56 and the second limit ring 57, wherein the second spring 55 is sleeved on the quick-release switching rod 51 positioned at the inner opening of the connecting fixed block 52; the first limit ring 56 is disposed at one end of the second spring 55 and is fixedly connected with the second spring 55 and the quick-release switching rod 51, so that the first limit ring not only can move along with the quick-release switching rod 51 and compress the second spring 55, but also can cooperate with the second spring 55 to drive the quick-release switching rod 51 to reset, and meanwhile limit the connection fixing block 52. The second stop collar 57 is disposed at an end of the quick release switching lever 51 to stop the switched quick release switching lever 51, so that the release position 511 corresponds to the position of the quick release block 53 when the second spring 55 is compressed.
One end of the quick release switching rod 51 is located in the through hole at the end of the connection fixing block 52, and the other end of the quick release switching rod 51 extends out of the other end of the connection fixing block 52 and is connected with the quick release handle 54. The quick release handle 54 is configured to receive an external force, so as to move the quick release switching rod 51 and compress the second spring 55, so that the release position 511 of the quick release switching rod 51 moves to a position corresponding to the quick release block 53, after the quick release block 53 is installed or removed, the external force disappears from the quick release handle 54, and the second spring 55 drives the quick release switching rod 51 to reset, so that the release position 511 is staggered with the installation slot of the quick release block 53, and the quick release block 53 is prevented from being released from the quick release switching rod 51.
Referring to fig. 5 to 7, the flexible ram 6 includes: an error absorbing module and a guide assembly 65 disposed at the bottom of the error absorbing module. Preferably, the error absorbing module includes: the pressure welding plate 61 connected with the guide assembly 65, set up in pressure welding plate 61 upper portion and with the lower floating plate 62 that pressure welding plate 61 connects, be located the upper floating plate 63 of lower floating plate 62 top, set up in angle adjustment plate 64 between upper floating plate 63 and the lower floating plate 62 and respectively with the elastic reset mechanism that lower floating plate 62 and upper floating plate 63 are connected, wherein, be provided with spherical protruding 621 in the middle of the top of lower floating plate 62, angle adjustment plate 64 bottom surface be equipped with spherical recess that spherical protruding 621 corresponds, namely upper floating plate 63 passes through spherical connection with lower floating plate 62, lower floating plate 62 and pressure welding plate 61 can rotate for upper floating plate 63, and then realize the error absorption. Specifically, the upper floating plate 63 is connected to the quick release mechanism 5 by a connecting bolt 66 and provides support and installation space for other components, and the guide assembly 65 is used for aligning with the crimping platform 14, deflecting when there is an angular displacement error with the crimping platform 14, and transmitting the angular displacement error to the elastic restoring mechanism through the crimping plate 61. The elastic restoring mechanism receives the angular displacement error of the crimping plate 61 through the lower floating plate 62 and drives the crimping plate 61 and the guiding assembly 65 to restore through the lower floating plate 62 after the guiding assembly 65 is separated from the crimping platform 14.
With continued reference to fig. 5 to 7, the elastic restoring mechanisms are provided at four corners of the lower floating plate 62 and the upper floating plate 63, respectively, so that error absorption at all angles can be achieved. The elastic reset mechanism comprises: the connecting support piece 67 and the first spring 68, wherein, the connecting support piece 67 and the lower floating plate 62 are in clearance fit, the top of the connecting support piece 67 is fixedly connected with the upper floating plate 63, and the first spring 68 is sleeved on the connecting support piece 67 and limited by the lower floating plate 62 and the bottom end of the connecting support piece 67. When the lower floating plate 62 is pushed down by the pressing plate 61 and the guide member 65, the lower floating plate is biased or inclined, and thus the first spring 68 is stretched or compressed, so that the first spring 68 is deformed. After the guide assembly 65 is separated from the crimping platform 14, the resilience of the first spring 68 drives the connection support 67 and the lower floating plate 62 to return to the original position.
The guide assembly 65 adopts 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 the press-in operation, it is necessary to insert a guide pin into the guide hole to achieve precise alignment. Because the mounting error problem exists in the crimping platform 14, in actual operation, the guide pin and the guide hole are not in a completely aligned state, so the bottom of the guide pin is preferably set to be an inverted cone frustum structure, and the diameter of the bottom surface of the inverted cone frustum structure is smaller than that of the top surface of the inverted cone frustum, namely, the diameter of the guide pin, so that the guide pin can smoothly enter the guide hole within a certain error range, offset errors are eliminated, and precise alignment is realized. Of course, when the bottommost end of the guide pin, namely the inverted cone frustum structure enters the guide hole, the bottommost end of the guide pin is deviated 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. Since 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 press 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 modifications and variations can be made to the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention also include such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
