DETAILED DESCRIPTION
[0013] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", "vertical", "horizontal", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0015] like Figures 1 to 4 As shown, the embodiment of the utility model includes a base plate 1, a lower die base 2 is fixed to the top of the base plate 1 through a pressure block locking assembly 3, and a cylinder 8 is arranged on the rear side through an L-shaped mounting plate 7; a slide groove 201 is arranged on the top of the lower die base 2, and the middle of the slide groove 201 is circular for placing a lock shell 13 and a sheath 14; sliding fixed blocks 4 are symmetrically arranged on both sides of the slide groove 201 for fixing the lock shell 13 and the sheath 14; limiting blocks 12 are arranged at both ends of the slide groove 201 for rebound limiting the sliding fixed block 4; the end of the sliding fixed block 4 is in an arc shape, and a conical riveting ejector pin 401 is arranged in the middle of the end; a lower wedge block 5 is arranged on the top of the sliding fixed block 4, and a spring 6 is arranged between the two lower wedge blocks 5; an upper template 9 is arranged at the output end of the bottom of the cylinder 8 through the L-shaped mounting plate 7, and an extrusion block 10 corresponding to the circular middle of the slide groove 201 is arranged in the middle of the bottom of the upper template 9, and upper wedge blocks 11 corresponding to the lower wedge blocks 5 are arranged at both ends.
[0016] First, Figure 3The lock shell 13 and the sheath 14 shown are placed in the circular shape in the middle of the slide groove 201, and then the cylinder 8 is started to drive the upper template 9 and its upper parts to press down. The upper wedge block 11 first presses against the lower wedge block 5. During the pressing process of the upper wedge block 11, the two lower wedge blocks 5 and the sliding fixed block 4 are pushed together, and the spring 6 is compressed. At this time, the extrusion block 10 and the upper wedge block 11 continue to press down into the lock shell 13, generating downward pressure on the lock shell 13, so that it is close to the sheath 14. The two sliding fixed blocks 4 squeeze the two sides of the sheath 14, and the riveting ejector pin 401 squeezes the sheath 14 and the lock shell 13 to make the contact point concave, preventing the sheath 14 from loosening and falling off after long-term use. After the lock shell 13 and the sheath 14 are riveted, the control cylinder 8 is contracted to drive the upper template 9 to return to the initial position, and then the sliding fixed block 4 rebounds and resets under the action of the spring 6, and then the lock shell 13 and the sheath 14 can be taken out.
[0017] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
