Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of wiring harness processing, in particular to an automobile wiring harness tightening device. BACKGROUND

[0002] In automobile production, it is often necessary to install and connect wiring harnesses. The stripping process of a multi-strand wiring harness generally includes feeding, stripping and cutting, etc. At present, the commonly known mechanical device for stripping the sheath of an automobile wiring harness is a stripping machine. Generally, the stripping machine only has the function of stripping the sheath of an electric wire. Thus, for a multi-strand wire core (such as a copper wire) of an electric wire harness, when the end of the wiring harness is stripped of a section of the sheath, the exposed wire core portion as a whole has low cohesion and tends to fork or scatter, which brings trouble to subsequent processing and affects the efficiency of electric wire processing and the quality of production.

[0003] The existing technology mostly tightens the stripped wiring harness through clamping jaws. However, in the process of tightening, the clamping jaws continuously rub against the wire core, which damages the surface of the wire core. Moreover, the position of the clamping jaws is not convenient to adjust. If the clamping jaws are close to the stripped part of the wiring harness, as the wire core forms a spiral shape, the wire core close to the stripped part of the wiring harness has already been tightened, while the end of the wire core is still in a loose state. At this time, if the step of tightening is continued, the wire core close to the stripped part of the wiring harness is prone to breakage due to excessive pressure. If the clamping jaws are close to the end of the wire core, the wire core at this position is too loose to be effectively tightened. After the tightening is completed, the wire core is still prone to scattering. In addition, when the wiring harness is tightened at a low temperature, the diameter of the wire core is very small and the brittleness is very high. Thus, the wire core is prone to breakage during the tightening.

[0004] Therefore, the present application provides an automobile wiring harness tightening device. SUMMARY

After the tightening is completed, the wire core is still prone to scattering.
