specifically, the guide block 61b contacts with the two guide wheels 64, and the guide surface of the guide block 61b is arranged in an arc line, where the arc line refers to that the distance between the arc lines of the two side surfaces of the guide block 61b close to the guide wheels 64 is gradually increased toward the direction away from the guide wheels 64, and when the guide block 61b contacts with the guide wheels 64 and moves toward the inner side of the guide wheels 64, the opening angle of the two shearing arms 63 is increased to drive the pressure welding block 62 to generate the same-direction angle change, so that the free end of the pressure welding block 62 is gathered toward the center. After the crimping is completed, the two shear arms 63 are drawn close to each other due to the elasticity of the extension spring 65, so that the pressure on the clamping part is relieved.
As shown in fig. 14, in the embodiment of the present invention, the feeding mechanism 70 is further adjusted to realize the feeding of the terminal ends of different types, specifically, a feeding adjustment mechanism 73 is further provided between the vibration tray 71 and the feeding pipe 72, the feeding adjustment mechanism 73 includes a first guide plate 73a, a second guide plate 73b and an adjustment screw 73c, the first guide plate 73a is fixed on the vibration tray 71, the second guide plate 73b is movably disposed, a feeding channel communicated with the feeding pipe 73 is formed between the first guide plate 73a and the second guide plate 73b, and the adjustment screw 73c is rotatably connected to the first guide plate 73a and engaged with the second guide plate 73b to adjust the distance between the feeding channels. The change of the distance between the first guide plate 73a and the second guide plate 73b is realized by the adjusting screw rod 73c, so that the distance of the material feeding channel for conveying the tubular terminal is changed, and the conveying of different crimping terminals is realized. It should be noted that the adjusting screw 73c is only one of the ways, and other common ways can be used to achieve the above functions.
It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
