Description

Technical Field

[0001] The invention relates to the technical field of wire harness stripping machines, in particular to a wire harness stripping machine for automobile wire harness assemblies. Background Art

[0002] When wiring the wire harness, it is usually necessary to first peel off the outer skin of the wire harness end to expose the conductive core so that the conductive core can be connected to other conductors. When the existing pneumatic stripping machine for automobile wire harness production is used, the cut rubber sleeve on the wire harness cannot be directly removed from the wire harness and needs to be pulled out manually, which greatly reduces the stripping efficiency of the wire harness.

[0003] To this end, a Chinese patent with publication number "CN216251973U" announced "a pneumatic stripping machine for automobile wire harness production", whose main structure includes a base, a first slide groove is provided on one side of the upper end surface of the base, a first clamping block is slidably installed in the first slide groove, a first fixed block is fixedly installed on the upper end surface of the base on the side close to the first clamping block, a movable plate is provided on one side of the upper end surface of the base, a second slide groove is provided on one side of the upper end surface of the movable plate, a second clamping block is slidably installed in the second slide groove, a second fixed block is fixedly installed on the upper end surface of the movable plate on the side close to the second clamping block, a plurality of gaskets are provided inside the second clamping block and the second fixed block, cutters and wire stripping rings are respectively provided between the plurality of gaskets, and a pressure sensor is installed on one side of the upper end surface of the base. This pneumatic stripping machine for automobile wire harness production achieves a clamping effect on the wire harness through the mutual cooperation of the first clamping block, the first fixed block and the second telescopic rod to prevent the wire harness from being displaced during stripping. The mutual cooperation among the second clamping block, the second fixed block, the third telescopic rod, the cutter and the wire stripping ring enables the third telescopic rod to perform a ring cut on the outer skin of the wire harness during operation. The cooperation of the installation gasket and the locking bolt facilitates the user to adjust the distance between the cutter and the wire stripping ring, and to replace cutters and wire stripping rings of different models, thereby greatly improving the working efficiency of the stripping machine.

[0004] When the wire harness is ring-cut, the pneumatic stripping machine for automobile wire harness production cooperates with each other through the sliding rod, the slider, the first telescopic rod and the movable plate, so that the first telescopic rod can drive the movable plate to move along the sliding rod when working, and then strip the outer skin of the ring-cut wire harness. The third telescopic rod, the controller and the pressure sensor are electrically connected, so that when the movable plate touches the pressure sensor, the pressure sensor sends an electrical signal to the controller, and the third telescopic rod is controlled by the controller to continue to extend and retract, so that the outer skin stripped by the ring cutting of the cutter is clamped by the wire stripping ring and stripped from the wire harness as the movable plate moves. However, in actual operation, since the movement of the cutter is vertical relative to the axis of the wire, it can only cut the wire in one direction, and cannot perform 360-degree ring cutting in the actual sense, resulting in that after cutting, after removing the cut wire skin, one end of the wire skin needs to be manually pulled, and the pulling force requires greater labor intensity because the wire skin is not completely cut, which seriously affects the stripping efficiency.
