DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-Figure 2 An embodiment of the utility model provides a wire harness cutting device for wire harness production, comprising: a bracket 1 and a wiring rack 2.

[0021] In this embodiment, Figure 1-Figure 3 As shown, a wiring rack 2 is installed on the top of the bracket 1, vertical plates 4 are installed on both sides of the bracket 1, horizontal plates 5 are installed on the opposite sides of the two vertical plates 4, an electric push rod 7 is installed on the bottom of the horizontal plate 5, and the piston rod of the electric push rod 7 is fixedly connected to the cutting blade 8, and the inner walls on both sides of the bracket 1 are fixedly connected to the annular shell 9, and the rod body 14 is rotatably installed inside the annular shell 9, and the outer wall of the rod body 14 is fixedly connected to the movable plate 3, and the tops of the wiring rack 2 and the movable plate 3 are provided with a plurality of cutting grooves 11 whose shapes match the cutting blade 8.

[0022] When in use, the wiring rack 2 and the movable plate 3 are used to place the wiring harness, and the cutting blade 8 is driven to descend into the cutting groove 11 by starting the electric push rod 7. During this process, the wiring harness located above the cutting groove 11 can be cut.

[0023] Reference Figure 1 and Figure 3 A plurality of arc grooves 6 are provided on the top of the wiring rack 2 and the movable plate 3. The arc grooves 6 can utilize the arc-shaped depressions to conveniently place and guide the wiring harnesses through the wiring rack 2 and the movable plate 3.

[0024] In this embodiment, Figure 1-Figure 5 As shown, a wedge block 15 is fixedly connected to one side of the cutting blade 8, a coil spring 18 is fixedly connected to the inside of the annular shell 9, the inner ring of the coil spring 18 is fixedly connected to the outer wall of the rod body 14, a groove 16 is provided on one side of the movable plate 3, and an arc block 13 is installed inside the groove 16 through a spring 17.

[0025] When the cutting blade 8 descends to the inside of the cutting groove 11 and cuts the wiring harness, the inclined surface of the wedge block 15 can squeeze the curved surface of the arc block 13 and push the arc block 13 to move into the groove 16. When the top plane of the wedge block 15 passes the bottom of the arc block 13, the spring 17 can push the arc block 13 to move outside the groove 16, so that the bottom of the arc block 13 extends to the top plane of the wedge block 15. When the electric push rod 7 drives the cutting blade 8 to lift and reset, the wedge block 15 can push the arc block 13 upward, thereby driving the rod body 14 to rotate and tilt the movable plate 3 toward the collection box 10. At the same time, the coil spring 18 shrinks and deforms, so that the cut wiring harness tilts and slides into the collection box 10.

[0026] refer to Figure 2The inner walls on both sides of the bracket 1 are fixedly connected to the limit blocks 12, and the limit blocks 12 are located at the bottom of one side of the movable plate 3. When the movable plate 3 is reset from the inclined state, the limit blocks 12 can play a position limiting role at the bottom of the movable plate 3 to prevent the movable plate 3 from resetting too much.

[0027] Specifically, a collecting box 10 is installed at the bottom of the bracket 1 , and an opening of the collecting box 10 is located below the movable plate 3 . The collecting box 10 can recover the wire harness cut and dropped from the movable plate 3 .

[0028] According to the above technical scheme, the working steps of this scheme are summarized and sorted out: when the utility model is used, the wiring rack 2 and the movable plate 3 are used to place the wiring harness, and the cutting blade 8 is driven to descend into the cutting groove 11 by starting the electric push rod 7. In this process, the wiring harness located above the cutting groove 11 can be cut.

[0029] Among them, when the cutting blade 8 descends to the inside of the cutting groove 11 and cuts the wire harness, the inclined surface of the wedge block 15 can squeeze the curved surface of the arc block 13 and push the arc block 13 to move into the groove 16. When the top plane of the wedge block 15 passes the bottom of the arc block 13, the spring 17 can push the arc block 13 to move outside the groove 16, so that the bottom of the arc block 13 extends to the top plane of the wedge block 15. When the electric push rod 7 drives the cutting blade 8 to lift and reset, the wedge block 15 can push the arc block 13 upward, thereby driving the rod body 14 to rotate and make the movable plate 3 tilt toward the collection box 10, so that the cut wire harness is tilted and slides into the collection box 10, realizing automatic recovery of the wire harness after cutting, without the need for the operator to manually collect the cut wire harness.

[0030] When the rod body 14 rotates to tilt the movable plate 3 toward the collecting box 10, the coil spring 18 contracts and deforms. When the cutting blade 8 is lifted upward and separated from the cutting groove 11, the coil spring 18 releases energy to drive the rod body 14 to rotate, so that the movable plate 3 is reset.

[0031] Parts not involved in the present invention are the same as the prior art or can be implemented by the prior art. Although the embodiments of the present invention have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the attached claims and their equivalents.
