Description
Technical Field
The invention belongs to the technical field of precision assembly of aerospace components, and particularly relates to a V-shaped bracket type elastic clamp hot stripping tool.
Background
The on-missile embedded cable means that the on-missile control system cable completes the laying work of the whole set of cable net when the composite material engine shell is formed and wound, and the laying mode is essentially different from the cable cover external hanging mode adopted by most of the existing models. Due to the limitation of the manufacturing process of the engine shell, before the cable is buried and laid, the electric connector assemblies at two ends of the cable cannot be installed on the buried cable, so that the assembly work of the whole set of cable is completed. At present, the assembly work of the spring-on-embedded cable electric connector assembly is carried out after the embedded cable is laid.
With the increasing integration degree of the equipment on the missile, the electromagnetic environment is more and more severe, the lead composition of the control system cable is also changed, and the proportion of the shielded twisted-pair cable, the 1553B bus and the network cable in the cable composition is gradually increased. How to complete the assembly work of the electric connector assembly on the embedded cable quickly, effectively and with high quality is one of the key points for improving the production efficiency of the engine. The stripping of the outer insulating sheath of the shielded cable is an important process in the assembling process of the embedded cable and the electric connector, the protection of the inner shielding layer and the lead from damage in the stripping process is an important protection object in the process, and because of the irreplaceable special property of the embedded cable product, the reliability of the lead in the embedded cable product has stricter production process quality requirements compared with the existing externally hung cable product. The mature hot stripping knife product in the market at present is simple in structure and comprises a heating knife head, a handle and a control console, and the wire diameter of the wire used by the embedded cable product is small, so that the wire cannot be directly and accurately operated on a single wire of the embedded cable product, therefore, the manual cold stripping process of the blade is still adopted in the production of the current embedded cable product, and the method has the following problems and disadvantages:
1) high risk
Due to the irreplaceability of the embedded cable, the damage of the blade to the cable conductor due to cold peeling is unpredictable, the blade is sharp, the surface of the twisted conductor is uneven, the shielding layer is scratched due to slight improper force, the shielding layer is damaged seriously, the shielding effect is reduced, or the insulation damage of the conductor and the breakage failure of the conductor are caused, so that the product quality is influenced.
2) Long time consumption
A single-sided blade is used for cutting the outer-layer insulating sheath of the lead with the diameter of about 5mm along the axial direction of the lead, and due to the fact that the surface of the twisted pair lead is uneven and fine, the moving speed of a cutter head is very slow, and one-time success cannot be guaranteed, so that a large amount of production time can be consumed, the production period is prolonged, and the productivity is influenced.
3) High personnel demand
Because the cold peeling of the blade belongs to manual operation, the requirements on the skill ability and the state of an operator are strict, and human factors can have uncertain influence on the quality of a product.
Therefore, optimizing the hot stripping process and designing and applying a high-efficiency and high-quality stripping tool for the outer insulation sheath of the shielded cable are new requirements along with the new development of embedded cable products.
