This invention relates to the field of cable harness assembly manufacturing technology, specifically disclosing a cable harness assembly manufacturing device and process, including a production frame. Feeding and mounting frames are fixedly installed on both sides of the top of the production frame, and a pressing and fixing frame is fixedly installed in the middle of the top of the production frame. Through the symmetrically arranged wire conveying components and crimping processing components on both sides, various production modes such as single-end crimping, simultaneous crimping at both ends, and continuous alternating crimping can be flexibly realized. During wire conveying, multiple clamping structures and synchronous transmission design ensure accurate positioning and stable conveying of multiple wires, avoiding the impact of conveying displacement on crimping accuracy. The stripping and twisting processes are integrated into the same processing component. Through the coordinated operation of ring cutting, straight cutting, and rotary twisting, precise control of the stripping size and reliable twisting of the copper wires are achieved, completely solving the short-circuit hazard caused by exposed loose wires, while ensuring the consistency of crimping end processing.
