V-shaped bracket type elastic clamp hot stripping cutter

Abstract

The invention discloses a V-shaped bracket type elastic clamp hot stripping tool. The tool comprises a V-shaped bracket, a tool bit, a sleeve, a tool handle, an elastic connecting rod, a power line, aheating assembly, a spring and a temperature control table. The end where the limiting table of the elastic connecting rod is located is installed in the rectangular groove of the tool handle, and the other end is fixedly connected with the connecting rod of the V-shaped bracket in a butt joint mode. The spring is located in the rectangular groove of the tool handle and installed outside the elastic connecting rod. One end of the sleeve is fixed at the end part of the tool handle; the heating pipe of the tool bit is coaxially arranged in the sleeve and is in interference fit with the sleeve;the concave cutting edge of the tool bit is opposite to the arc-shaped groove of the V-shaped bracket; the heating assembly is installed in the heating pipe of the tool bit. The heating assembly is electrically connected with the temperature control table through a power line, and the temperature control table is used for controlling the heating assembly to heat the tool bit. The outer-layer insulating sheath for the non-destructive stripping wire has the functions of axially cutting and radially girdling the outer-layer insulating sheath of the wire.

Description

technical field [0001] The invention belongs to the technical field of precision assembly of aerospace parts and components, and in particular relates to a V-shaped bracket type elastic clip hot stripping tool. Background technique [0002] Bouncing the buried cable means that the cable of the control system on the flick is formed and wound on the composite material engine casing to complete the laying of the whole set of cable network. The laying method is essentially different from the external cable cover method adopted by most existing models. the difference. Due to the limitation of the manufacturing process of the engine casing, it is impossible to install the electrical connector assemblies at both ends of the cable on the embedded cable before the cable is buried in it to complete the assembly of the whole set of cables. At present, the assembly work of the embedded cable electrical connector assembly must be carried out after the embedded cable is laid. [0003] W...

AI Technical Summary

Problems solved by technology

At present, the mature thermal stripping knife products on the market have a simple structure, consisting of a heating knife head, a handle and a console. Due to the small diameter of the wire used in the embedded cable product, it cannot be directly on a single wire of the embedded cable product. Precise operation, therefore, in the current production of embedded cable products, the process of manual cold stripping of blades is still used. This method has the following problems and shortcomings:

[0005] Due to the irreplaceability of the embedded cable, the damage to the cable conductor caused by cold stripping of the blade is immeasurable, because the blade is sharp, and the surface of the twisted-pair conductor is uneven. Slight improper force will cause scratches on the shielding layer, and serious damage to the shielding layer. The shielding effect is reduced or the wire insulation is damaged and the wire is broken and fails, which affects the product quality

[0006] 2) Time-consuming

[0007] Use a single-sided blade to cut the outer insulating sheath of the wire with a diameter of about 5mm along the axial direction of the wire. Due to the uneven and small surface of the twisted-pair wire, the moving speed of the cutter head is very slow, and one-time success cannot be guaranteed, so It will consume a lot of production time, resulting in a longer production cycle and affecting production capacity

[0008] 3) High personnel requirements

[0009] Since the cold stripping of blades is a manual operation, there are strict requirements on the skills and conditions of operators, and human factors will have an uncertain impact on product quality
