Description

Technical Field

[0001] The utility model relates to the technical field of wire harness production, in particular to a cutting device used for wire harness production. Background Art

[0002] Wire harness production mainly involves the process of combining multiple wires, cables or optical fibers together and fixing them into a wire harness through insulating materials or outer packaging. Wire harness cutting is to cut the batch of continuous wire harnesses into wires of specified length according to the requirements of the product drawings for subsequent processing.

[0003] After searching, the patent with application number CN202120334994.6 discloses a cutting device for automobile wiring harness production, including a base, and motors are fixedly connected to the left and right ends of the inner side of the base, and a first screw is fixedly connected to the end of the motor main shaft, and a slider is spirally connected to the outer side of the first screw, and a fixed block is fixedly connected to the top of the slider, and an arc-shaped extrusion plate is slidably connected to the inner side of the fixed block. The utility model can fix automobile wiring harnesses of different specifications through the fixed block, and the fixing effect is good. The length of the cut automobile wiring harness can be adjusted by driving the slider to move by the right motor. The operation is simple and convenient. The automobile wiring harness is squeezed by the arc-shaped fixed plate, so that the two ends of the cutting place are fixed to prevent the cut automobile wiring harness from moving, thereby improving the cutting effect. The spring is squeezed by the second limit block, so that the cutting knife moves inside the cutting groove to improve the cutting effect. It has broad market value and is worthy of promotion.

[0004] The current wire harness cutting devices mostly use one or two directions (i.e. one or both of the X-axis, Y-axis or Z-axis) to position the wire harness before cutting it. The effect of positioning the wire harness needs to be strengthened so that the cuts of the wire harness are more neat and the size errors of multiple wire harnesses cut at one time are small. Moreover, the current wire harness cannot be automatically returned after cutting, and the cut wire harness needs to be manually removed, which is time-consuming and labor-intensive and increases the workload of the staff. Therefore, we propose a cutting device for wire harness production. Utility Model Content

[0030] The cutting mechanism 2 can cut multiple wire harnesses at one time, and the cuts after cutting are smooth and neat. The pressing mechanism 3 is used to ensure the stability of the wire harness during cutting to prevent the ends of the wire harness from warping up, which in turn causes uneven cuts. The clamping mechanism 4 clamps on both sides of a row of wire harnesses and makes a row of wire harnesses fit tightly together to prevent the wire harnesses from moving. The alignment mechanism 5 can ensure that the ends of the wire harnesses are flush, so that the length errors of the multiple wire harnesses after cutting are small, thereby ensuring the quality of the wire harnesses.

[0031] The pressing mechanism 3 includes a second fixed frame 31, on which a second cylinder 32 is installed, one end of the piston rod of the second cylinder 32 is connected to a second mounting frame 33, and a pressing plate 34 is arranged at the lower end of the second mounting frame 33; the second cylinder 32 is operated to drive the second mounting frame 33 to move downward, and the pressing plate 34 to move downward, so that the pressing plate 34 is pressed on the top of the wire harness, thereby increasing the stability of the wire harness and preventing it from warping during the cutting process.

Racks 56 are installed at the lower ends of both sides of the baffle 55, and the gear 54 is meshed with the racks 56. The second motor 52 drives the rotating shaft 53 and the gear 54 to rotate.
