Description

Technical Field

[0001] The utility model relates to the technical field of automobile wiring harnesses, in particular to an automobile wiring harness processing and equidistant cutting device. Background Art

[0002] A wiring harness is a component that is formed by crimping contact terminals (connectors) punched from copper materials with wires and cables, and then plastic-pressing an insulator or adding a metal shell to the outside to form a wiring harness to connect the circuit. The automotive wiring harness is the network body of the automotive circuit, connecting the electrical and electronic components of the car and enabling them to function. Without the wiring harness, there would be no automotive circuit. In order to facilitate installation and maintenance and avoid entanglement, multiple wires are usually bundled into a wiring harness and covered with a protective cover.

[0003] In the process of processing automobile wiring harnesses, they are usually bundled first and then cut, so a cutting device is needed to cut the wiring harnesses.

[0004] When using a cutting device to cut automotive wiring harnesses, most of the time, the wiring harnesses are manually dragged and cut using a cutting knife. However, the cutting distance cannot be adjusted during the cutting process, resulting in different cutting lengths for the wiring harnesses, which leads to uneven cutting and reduced cutting quality. In addition, offset may occur during the cutting process, resulting in uneven layers at the ends of the automotive wiring harnesses, affecting the cutting effect. Utility Model Content

[0005] The purpose of the present invention is to provide an equidistant cutting device for processing automotive wiring harnesses, so as to solve the problem mentioned in the background art that the existing cutting device is not convenient for equidistant cutting and is not convenient for fixing and clamping the wiring harness, resulting in uneven layers at the ends of the automotive wiring harness.

[0038] It should be noted that the slide plate 12 is limited and supported by the limiting plate 92 so that the slide plate 12 can slide up and down stably. At the same time, the slide groove 91 on the surface of the mounting plate 9 is used to facilitate the horizontal sliding of the nut slider 1204 therein.

[0039] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, a fixing plate 1201 is fixed to the top of the mounting plate 9, and a rocker 1202 is rotatably connected to the top of the fixing plate 1201.
