[0033] As Figures 3 to 4As shown in the figure, based on the same concept as in the above-mentioned Embodiment 1, this embodiment also proposes that threaded blocks 206 are threadedly connected to the outer surfaces of both threaded rods 205.

Clamping plates 208 are fixedly connected to the side surfaces of both threaded blocks 206 away from the threaded rods 205. A connecting rod 209 is fixedly connected to the front surface of the hydraulic cylinder 201, and a rotatable and detachable positioning disk 2010 is sleeved on the outer surface of the connecting rod 209. Mold bodies 2011 arranged in an annular array are fixedly connected to the outer surface of the positioning disk 2010.

[0034] Reference Figures 2 to 4 , the arrangement of the threaded block 206 can move closer to or away from each other under the drive of the threaded rod 205, so that the positioning disk 2010 can be clamped and fixed through the limiting groove 207 and the clamping plate 208, thus facilitating the crimping work of the wire harness. And the arrangement of the positioning disk 2010 can not only be grasped at the connecting rod 209, but also be convenient for disassembly and installation, so that different crimping components can be used to crimp the wire harness according to needs, greatly improving the application range and practicability of the overall device.

[0035] A bearing 2012 is embedded in the front surface of the positioning disk 2010, and the inner ring of the bearing 2012 is fixedly connected to the outer surface of the connecting rod 209. A hexagonal nut 2013 is threadedly connected to the outer surface of the connecting rod 209, and the hexagonal nut 2013 is located outside the positioning disk 2010.

[0036] By providing the bearing 2012, it is better to facilitate the rotation and disassembly of the positioning disk 2010, so that the positioning disk 2010 can be quickly disassembled and replaced by rotating the hexagonal nut 2013. Furthermore, different crimping components can be installed according to needs, and different types of mold bodies 2011 can be used to crimp the wire harness by rotating the positioning disk 2010, greatly improving the application range and practicability of the device.

[0039] The specific implementation process of the utility model is as follows: when crimping the wire harness, first, the required mold body 2011 is rotated to the top of the placement frame 5 by rotating the positioning disk 2010, and the two output shafts of the dual output shaft motor 203 are started. The two output shafts of the dual output shaft motor 203 drive the two threaded rods 205 to rotate under the limiting action of the first limiting block 204, so that the threaded rod 205 drives the threaded block 206 to move horizontally, so that the two threaded blocks 206 are clamped to each other, so that the threaded block 206 drives the clamping plate 208 to clamp and fix the positioning disk 2010 under the limiting action of the limiting groove 207 , so that it is easy to clamp the positioning disk 2010 stably, and avoid slight shaking of the positioning disk 2010 when crimping the wire harness through the mold body 2011. When the positioning disk 2010 needs to be replaced or removed, first rotate the hexagonal nut 2013 to take out the positioning disk 2010, so as to quickly replace the positioning disk 2010, which greatly improves the rapid replacement and clamping of the crimping parts by the overall device. After the adjustment is completed, by starting the hydraulic cylinder 201, the hydraulic cylinder 201 pushes the L-shaped pushing plate 202 and other linkage parts to descend, so that the mold body 2011 crimps the wire harness stored in the placement frame 5.
