Description

Technical Field

[0001] The invention belongs to the technical field of cable manufacturing, and in particular relates to a universal aviation cable harness fixing device and a use method thereof. Background Art

[0002] The first key process in the manufacturing of aviation cable harnesses is wire cutting and forming. The cutting length is directly related to whether the product is qualified and the production cost. When the wire cutting length is too long, it will cause secondary trimming, which will increase the workload and increase the manufacturing cost, resulting in wire waste; when the wire cutting length is too short, it will cause inadequate installation and laying, resulting in cable scrapping. Therefore, the wire cutting length needs to be controlled within a reasonable optimal range to ensure the product is qualified while reducing the wire secondary trimming margin, thereby controlling the production cost.

[0003] At present, the field of aviation cable manufacturing technology lacks corresponding wire harness fixing methods and devices in the conductor unloading process. Usually, the operator inserts pins on the wiring table as fixing points. During the unloading process, the operator fixes the wire from end to end on the pins by wrapping and knotting it. Although this method can play a fixing role, the wires in the wrapped and knotted parts are squeezed and deformed and cannot be reused, so they can only be trimmed as surplus. According to statistics, the trimming margin of 200mm is required for fixing the wire ends of a single wire by the winding and knotting method. The estimated trimming margin of the wire ends of a single machine is at least 2,000 meters, and the direct economic loss is at least 30,000 yuan. Summary of the invention

[0004] Technical problem solved by the present invention: The present invention provides a universal cable harness fixing method in combination with the existing production and processing operation procedures. This method can effectively fix the ends of wires of various models and specifications (from end to end) during the wire cutting process, thereby reducing the wire trimming margin and reducing the waste of wire materials.

[0005] The technical solution of the present invention:

[0006] On the one hand, the present invention provides a universal aviation cable harness fixing device, the device comprising: a plug-in base 1, a wire clamping module 2, a harness belt tensioning module 3, and a flexible harness belt 4;

[0007] The wire clamping module 2 and the wire harness tensioning module 3 are respectively fixedly connected to the two ends of the upper surface of the plug-in base 1, and the plug-in base 1 is fixed on the wiring platform;

[0008] One end of the flexible wire harness belt 4 is fixedly connected to the wire clamping module 2 , and the other end passes through the wire clamping module 2 and the wire harness belt tensioning module 3 and extends to the outside of the wire harness belt tensioning module 3 .

[0009] Furthermore,

[0010] The plug-in base 1 consists of a base plate 11 and a plug-in pin 12. The plug-in pin and the base plate are designed as an integrated unit. The plug-in pin can be directly inserted into the wiring platform, and the entire device is connected to the wiring platform through the pin and the pin hole to form a whole.

[0011] Furthermore,

[0012] The wire clamping module 2 consists of two parts: a surrounding wire block 21 and a wire harness fixing screw 22. The wire clamping module is fixed on the plug-in base. The top of the surrounding wire block is in an arc shape, and a groove 211 for placing the wire is opened on the top. The wire is directly placed into the groove. When the number of wires increases, the wires between the grooves are stacked to form a stable triangular relationship; two screw holes 212 are opened on the lateral side of the wire clamping module for fixing the end of the wire harness, and the screw holes and the wire harness fixing screws are reliably connected through threads; below the screw holes is a wire harness through hole 213 for the wire harness to pass through the wire clamping module.

[0018] The flexible wiring harness 4 is fixed by the wiring harness fixing screws of the wire clamping module, wrapped around the wire clamping module, and passed through the wiring harness passing holes of the wire clamping module, the limit block, and the lifting block. The wire clamping state can be achieved by pulling the wiring harness end 41; by pulling the lifting button, the wiring harness passing holes of the limit block and the lifting block can be overlapped, so that the wiring harness can be relaxed.

[0031] In order to solve the above technical problems, the present invention is implemented through the following technical solutions:

[0032] During the wire cutting process, the pin of the cable harness fixing device is inserted into the socket of the wiring table for fixing; the wire end is inserted into the groove between the harness belt and the surrounding wire block, and the gap between the harness belt and the surrounding wire block is reduced by pulling the tail section of the harness belt extended by the limit block, so that the wire end is clamped and fixed; by pulling the pull button, the through hole of the pulling block and the limit block are overlapped, and at this time, the flexible harness belt retracts by itself due to its own elastic force, so that there is a gap between the harness belt and the surrounding wire block, so that the flexible harness belt is in a relaxed state.

[0033] When the next wire needs to be fixed, just pull the button, the flexible cable tie will loosen automatically, and the wire will be inserted and tightened and fixed by repeating the above steps, and finally a cable harness is formed.

[0034] Preparatory action: During the wire cutting process, insert the pins of the cable harness fixing device into the wiring table socket to fix it;

[0035] Clamping action: The wire end is inserted into the groove between the wire harness and the wire block. By pulling the tail section of the wire harness extended from the limit block, the gap between the wire harness and the wire block is reduced, so that the wire end can be clamped and fixed;

[0036] Relaxation action: By pulling the lifting button, the through holes of the lifting block and the limit block are overlapped. At this time, the flexible wire harness belt retracts by itself due to its own elastic force, so that there is a gap between the wire harness belt and the surrounding wire block, so as to achieve a relaxed state of the flexible wire harness belt.

[0037] Each wire clamp only needs to be clamped by pulling the tail end of the harness belt, and then the wire can be relaxed by pulling the button, making it easier to clamp the next wire. This reciprocating process will eventually clamp all the wire ends and form an aviation cable harness.
