A plurality of horizontally distributed wire harness grooves 2 are formed on the top wall of the production table 1. The plurality of wire harness grooves 2 are evenly spaced in the horizontal direction, so that a wire harness formed by bundling a plurality of wires can be placed in the wire harness grooves 2, and synchronous cutting of a plurality of wire harnesses can be achieved in the plurality of wire harness grooves 2.

The transmission rod 6 is vertically arranged and connected to the bottom wall of the receiving frame 4, so that the transmission rod 6 has a stable structure and can be stably extended and retracted, wherein a horizontal lifting plate 7 is fixedly welded to the bottom of the transmission rod 6, and the wire harness cutting mechanism includes a plurality of arc-shaped blade heads 8 welded to the bottom wall of the lifting plate 7 and distributed at equal intervals, and an arc-shaped inner wall is provided below each arc-shaped blade head 8, so as to facilitate cutting of a wire harness formed by bundling a plurality of wires, and a cutting groove 15 is provided in each of the plurality of wire harness grooves 2 and penetrates to the bottom wall of the production table 1, and the plurality of cutting grooves 15 are respectively located directly below the plurality of arc-shaped blade heads 8;

[0023] Ear plates 9 are symmetrically provided on both sides of each arc-shaped cutter head 8, and the ear plates 9 on both sides of the arc-shaped cutter head 8 are welded to the lifting plate 7, a casing 10 is welded on the bottom wall of each ear plate 9, and a receiving groove 11 is formed on the bottom wall of each casing 10, and a spring 12 and a piston block 13 connected to each other are provided in each receiving groove 11, the spring 12 is vertically arranged, and the two ends of the spring 12 are respectively connected to the top wall of the receiving groove 11 and the piston block 13, and the side wall of the piston block 13 is fitted with the inner wall of the receiving groove 11, so that the spring 12 can drive the piston block 13 to extend and retract in the vertical direction when it is extended and retracted, and an elastic pressure platform 14 is fixedly bonded to the side of the piston block 13 facing away from the spring 12.

[0024] The construction machinery body wiring harness production and cutting device: when in use, firstly, a plurality of wiring harnesses to be cut are respectively inserted from the outside into a plurality of wiring harness grooves 2 through a plurality of penetration holes 3.
