Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a wire harness shearing machine. Background Art

[0002] The wiring harness is a connection line used to connect the main power socket to individual electrical devices. On existing trailers, the wiring harness connects the front of the vehicle and the semi-trailer, and controls the operation of the lamps and electrical equipment on the semi-trailer through specific lines.

[0003] When the wiring harness is manufactured, it needs to be cut and the connector needs to be installed according to the distance between the power connector and the electrical appliance. In complex wiring harnesses, branches need to be extended so that multiple electrical appliances can be connected to one line.

[0004] However, in the existing production of wire harnesses, a cutting machine is usually used to cut the wire harnesses according to length, and the short wires of fixed length are obtained and then welded to obtain a wire harness with branch lines. The complete wire harness needs to be divided into multiple sections and then re-joined, resulting in the defect of inconvenient processing.

[0005] Based on this, the utility model designs a wire harness shearing machine to solve the above problems. Utility Model Content

[0006] The utility model aims to provide a wire harness shearing machine to solve the above technical problems.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solution: it includes a frame; a fixed platform is fixedly arranged on the frame, a lower give way groove is provided on the fixed platform, a lower cutting knife is fixedly arranged on the lower give way groove, and two lower cutting knives are provided; a mounting platform is fixedly arranged on the frame, a first cylinder is fixedly arranged on the mounting platform, a movable block is fixedly arranged on the output shaft of the first cylinder, an upper give way groove is provided on the movable block, an upper cutting knife is fixedly arranged in the upper give way groove, and two upper cutting knives are provided; a give way hole is provided in the upper give way groove, a second cylinder is fixedly arranged in the give way hole, and a breaking knife is fixedly arranged on the second cylinder.

[0008] By adopting the above technical solution, when making a wiring harness branch, the wires to be branched are placed in the lower makeshift groove, and the movable block is pressed down so that the upper and lower cutters in the upper and lower makeshift grooves complete the ring cutting of the insulation layer of the wires, and the insulating layer after the ring cutting is cut off by the breaking knife, making the operation of branch line welding easier.

[0009] Preferably, a mounting rod is fixedly provided on the frame, a nozzle is fixedly provided on the mounting rod, an air pipe is connected to the nozzle, the other end of the air pipe is connected to an air pump, and the air pump is fixedly provided on the frame.

[0010] By adopting the above technical solution, when stripping the insulation layer at both ends of the wire, the wire is pulled out after the insulation layer is ring-cut, and the insulation layer left in the lower yielding groove is blown off by the gas blown out by the nozzle, avoiding delay in the processing of the next section of the wire.

[0011] Preferably, a resistance block is fixedly arranged in the lower yielding groove.

[0012] By adopting the above technical solution, when the insulating layer is peeled off, the abutment block can press the insulating layer tightly, so that the insulating layer can be easily removed from the electric wire.

[0013] Preferably, the material of the resistance block is flexible rubber.

[0014] By adopting the above technical solution, the friction coefficient between the flexible rubber and the insulation layer of the wire is large, which makes it easier to strip the insulation layer. At the same time, the flexible rubber is elastic, which prevents the wire from being worn by the upper cutter and the lower cutter during stripping.

[0015] Preferably, a waste hole is provided on the frame, and a waste bag is sleeved on the waste hole.

[0016] By adopting the above technical solution, the insulation layer blown off from the lower relief groove can be collected in a waste bag, avoiding clutter in the working area.

[0031] The implementation principle of this embodiment is as follows: when it is used, when it is necessary to strip the insulation layer of the end of the wire, the wire is placed in the lower yielding groove 9, and then the first cylinder 13 is driven to work, and the telescopic shaft of the first cylinder 13 is extended to drive the movable block 14 to approach the fixed platform 8 until the movable block 14 and the fixed platform 8 are in contact with each other. At this time, the insulation layer of the wire is cut by the upper cutter 16 and the lower cutter 10. The worker can strip the insulation layer by pulling out the wire, and then drive the air pump 7 to work. After the airflow is ejected from the nozzle 5, the insulation layer left in the lower yielding groove 9 is blown off, so that it is collected in the waste bag 3 through the waste hole 2; when it is necessary to strip the insulation layer in the middle of the wire When making a branch circuit, the wire is placed in the lower yielding groove 9, and then the first cylinder 13 is driven to work.
