Description

Technical Field

[0001] This invention relates to the field of aerospace product assembly, and in particular to a wire diameter adaptive aerospace cable threading and guiding device. Background Technology

[0002] In the manufacturing process of spacecraft electrical systems, the stripping, threading, and crimping of aerospace cables are among the key technological steps affecting the reliability of electrical connections. Traditional stripping, threading, and crimping equipment uses fixed apertures that cannot be adaptively adjusted. When dealing with aerospace cable networks containing conductors of various wire gauges, problems such as jamming, wire piling, and wire leakage frequently occur during the threading process, seriously affecting assembly quality and efficiency.

[0003] In existing technologies, some devices attempt to adapt to different wire diameters by using multi-station switching or manual adjustment of the wire aperture, but these methods suffer from problems such as complex structure, low adjustment efficiency, and susceptibility to human error. Therefore, there is an urgent need for a guiding device that can automatically adapt to different wire diameters and improve threading accuracy and reliability to meet the high reliability requirements of aerospace cable networks. Summary of the Invention

[0004] The technical problem solved by this invention is to overcome the shortcomings of the prior art and provide a wire diameter adaptive aerospace cable threading guide device that adapts to the threading requirements of cables with different wire diameters and improves threading accuracy and efficiency.

[0005] The technical solution of the present invention is as follows: Firstly, a wire diameter adaptive aerospace cable threading and guiding device is provided, comprising:

[0006] The guide nozzle body has a gradually converging guide channel inside;

[0007] An elastic adjustment mechanism is provided at the converging end of the guide channel to automatically adjust the clamping gap of the cable according to the cable diameter.

[0008] The detection unit is used to monitor the position and diameter of the cable entering the guide nozzle body in real time;

[0009] A servo drive module, connected to the detection unit and the elastic adjustment mechanism, is used to receive the output signal of the detection unit and dynamically adjust the elastic adjustment mechanism so that the clamping gap of the elastic adjustment mechanism is adapted to the diameter of the clamped cable.

[0010] Furthermore, a flow guide groove is provided at the outlet of the guide nozzle body to prevent the core wires from becoming scattered after the cable is stripped.

[0011] Furthermore, the guide channel is a spiral guide channel.

[0012] Furthermore, the elastic adjustment mechanism consists of multiple sets of butterfly springs.

[0013] Furthermore, the detection unit is an optical detection unit.

[0014] Furthermore, the optical detection unit is aligned with the outlet of the guide nozzle body.

[0015] Furthermore, the guide nozzle body is made of an alloy material whose wear resistance meets preset requirements.

[0016] Secondly, a method for guiding the threading of aerospace cables is provided, employing the wire diameter adaptive aerospace cable threading guide device as described above, including the following steps:

[0017] The cable is fed into the guide channel of the guide nozzle body;

[0018] The cable is initially clamped and centered using the elastic adjustment mechanism.

[0019] The detection unit detects the diameter and position of the cable in real time.

[0020] Based on the diameter and position detected by the detection unit, the clamping gap of the elastic adjustment mechanism on the cable is adjusted by the servo drive module.

[0021] The cable smoothly exits through the main outlet of the adjusted guide nozzle.

[0022] Furthermore, after the cable exits, the stripped core wires are bundled and guided through the guide groove to prevent them from becoming scattered.

[0023] The advantages of this invention compared to the prior art are:

[0024] (1) High adaptability: The technical solution proposed in this invention can automatically adapt to a variety of wires without manual intervention, which significantly improves production efficiency;

[0025] (2) High reliability: The technical solution of this invention is designed with an elastic adjustment structure. Combined with the real-time position feedback of the cable, the clamping force is dynamically adjusted to ensure that the cable is centered and transported stably. In the automatic stripping-threading-crimping test of AWG30~AWG20 conductors, the success rate of wire threading of this device is 99.9% and the crimping qualification rate is 100%. Compared with the traditional fixed conductor device (threading success rate of about 90%), the performance is significantly improved.

[0026] (3) Anti-core wire stacking design: The technical solution of this invention effectively solves the problem of core wire stacking during the wire threading process and reduces the scrap rate;

[0027] (4) Process consistency: This invention is applicable to the mass production of aerospace electrical products and improves the assembly quality of cable network components. Attached Figure Description
