Description

Technical Field

[0001] The utility model relates to the field of wire harness arrangement, in particular to a wire harness arrangement and cutting device. Background Art

[0002] Wire harness refers to the wires that transmit electric energy, which are mainly divided into bare wires, electromagnetic wires and insulated wires. Bare wires have no insulation layer. Electromagnetic wires are insulated wires that generate magnetic fields or induce currents in magnetic fields after being energized. Insulated wire conductors are mainly copper wires. Wire harnesses should have a thin insulation layer and good electrical and mechanical properties, as well as heat resistance, moisture resistance, solvent resistance, etc. Wire harnesses provide the overall service equipment for a certain load source group, such as relay lines, switching devices, control systems, etc.

[0003] The wire harness is usually provided in a roll, and its diameter is very small compared to its length; the rolled wire harness is not convenient to use, and in order to facilitate the use of the wire harness, the wire harness needs to be cut into required lengths.

[0004] Since the cross-section of the wire harness is circular, when the cutting structure contacts the wire harness, the curved outer surface will cause the wire harness to rotate due to the force applied, causing the cutting to slip. Although the cutting work can be completed normally, the cutting surface is uneven, affecting the quality of the wire harness itself. Utility Model Content

[0005] The purpose of the utility model is to provide a wire harness arranging and cutting device to solve the problem raised in the above background technology that since the cross-section of the wire harness is circular, when the cutting structure contacts the wire harness, the wire harness will be rotated by the force due to the curved outer surface, causing the cutting to slip. Although the cutting work can be completed normally, the cutting plane is uneven, affecting the quality of the wire harness itself.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wire harness arranging and cutting device, comprising a cutting table, both sides of the front and rear ends of the cutting table are fixedly connected with legs;

[0007] A lower supporting platform is fixed on one side of the upper end of the cutting platform, and a wire harness fixing groove is opened equidistantly on the upper surface of the lower supporting platform from front to back, and a side rectangular empty groove is opened inside the lower supporting platform along the space between two adjacent wire harness fixing grooves and the outer end of the lower supporting platform at the outer end, and fixed sliders are slidably connected to the two sides of the wire harness fixing groove, and the middle of the inner end surface of the fixed slider is arc-shaped, and an outer sleeve is fixed to the outer end of the fixed slider, and an inner middle rod is slidably connected to the inside of the outer sleeve, and a side movable disk is fixed to the other end of the inner middle rod, and a fixed seat is fixed in the middle of the other end of the side movable disk. A linkage rod is rotatably connected to the fixed seat through an axis, and the other end of the linkage rod at the outer end and the other ends of the corresponding two linkage rods in the side rectangular empty groove at the inner end are both rotatably connected to a downward pressure rod through an axis.

[0008] Preferably, a pressure spring is arranged between the fixed sliding block and the side movable plate along the outside of the outer sleeve and the inner middle rod.

[0009] Preferably, a rectangular extension groove is provided at the connection position between the upper end surface of the lower support platform and the lower pressure rod, and the lower pressure rod slides along the rectangular extension groove.

[0010] Preferably, a cutting groove is provided in the middle of the inner end surface of the fixed sliding block.

[0011] Preferably, a cutting unit is provided on one side of the upper end of the cutting table, four supporting columns are provided on the cutting unit and are fixed to the cutting table, the lower supporting platform is located between the four supporting columns, an upper fixing plate is commonly fixed to the upper ends of the four supporting columns, a driving cylinder is installed in the middle of the upper end of the upper fixing plate, a lower pressure plate is fixed to the lower end of the upper fixing plate along the output rod end of the driving cylinder, the upper end of the lower pressure rod is connected to the lower pressure plate, a cutting knife is fixed to the lower end of the lower pressure plate, the cutting knife corresponds to the position of the wiring harness fixing groove up and down, and the size of the cutting knife is larger than the size of the cutting groove.

[0012] Preferably, two ends of the upper end of the lower pressing plate are fixed with limiting sliding rods, and the limiting sliding rods slide along the upper fixed plate.

[0013] Preferably, a placement basket is fixed on the other side of the lower end of the cutting table, the interior of the placement basket penetrates upward to the upper end surface of the cutting table, a limiting fixing plate is fixed along the outer side of the placement basket on the other side of the upper end of the cutting table, and a material discharge trough is opened on the outer side of the placement basket, which is connected to the interior of the placement basket.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] In the utility model, the output rod end of the driving cylinder extends to drive the lower pressure plate to press down, and the lower pressure rod fixed to the lower pressure plate moves downward. Due to the axial rotation connection relationship between one end of the lower pressure rod and the linkage rod, the linkage rod is driven to rotate to a horizontal state, and the fixed seat, the outer sleeve, the inner middle rod, the side moving plate, the pressure spring and the fixed slider are pushed to move in the direction of the wire harness as a whole through the axial rotation connection relationship with the fixed seat, and the inner end surface of the fixed slider gradually fits the surface of the wire harness; as the lower pressure plate continues to move downward, the outer sleeve, the inner middle rod and the pressure spring are gradually compressed, so that the fixed slider presses the two ends of the wire harness. In this way, the two sides of the wire harness are always fixed during the cutting process of the wire harness, and the wire harness is not easy to rotate due to the force, thereby avoiding the problem of uneven cutting plane. The problem that the wire harness cross section is circular, when the cutting structure contacts the wire harness, the wire harness will rotate due to the force due to the curved outer surface, causing the cutting to slip, although the cutting work can be completed normally, the cutting plane is uneven, affecting the quality of the wire harness itself.

[0016] In the utility model, the output rod end of the driving cylinder extends to drive the lower pressure plate to press down, and the fixed slider presses the wire harness; the lower pressure plate is pressed down so that the fixed slider is driven to further fix the wire harness, and the cutting knife moves downward, gradually contacts the upper end of the wire harness and cuts downward into the cutting groove. That is, the two driving processes do not introduce redundant driving structures, and only one driving structure is used to complete the two driving processes, so that the driving coordination of the entire structure is better and the integrity is stronger.
