Description

Technical Field

[0001] The utility model relates to the technical field related to wire harness shearing, in particular to a wire harness shearing device. Background Art

[0002] The wire harness is the overall service equipment for a certain load source group, such as relay lines, switching devices, control systems, etc. The wire harness needs to be cut during the production process. In order to assist in the convenient and efficient cutting of the wire harness, a wire harness cutting device is required.

[0003] The prior art has the following deficiencies: the prior art "an automobile wire harness cutting device" with a publication number of CN218619544U "includes a base and a cutting assembly installed on the base, a fixing mechanism and an equidistantly arranged positioning mechanism are provided on the base, a fixing plate is fixedly connected to the base, the fixing mechanism includes a slot provided on the base and a screw rod rotatably connected in the slot, a forward and reverse motor is installed on one side of the base, and the output shaft of the forward and reverse motor is connected to the screw rod, a moving frame is slidably provided on the inner wall of the slot, and the moving frame is threadedly sleeved on the screw rod, a screw rod is threadedly connected to the moving frame, and a clamping plate is rotatably connected to the bottom end of the screw rod";
