Problems solved by technology

This type of coil requires that the coils be firmly bonded to each other by heating, and it is sufficient that no loose wires occur in the working environment. For control, when several coils need to be removed to adjust the electrical performance, the insulating varnish on the inner layer of the enameled wire may be peeled off due to the excessive bonding force between the coils, resulting in insulation problems in the skeleton coil

Abstract

The invention relates to a tool for testing bobbin coil binding power and a method therefor. The tool comprises a guide rail base (1), a first suspended rod (2), a first lock screw (3), a load (4), a bobbin coil (5), a central spindle (6), a second lock screw (7) and a second suspended rod (8). At the tangential direction of the outmost coil layer of the bobbin coil (5), the load (4) is hung on a self-adhesive varnished wire at an end of the bobbin coil (5), the weight of the load (4) is increased gradually until the self-adhesive varnished wire on which the load (4) is hung is separated from the bobbin coil (5), and then the weight of the load (4) is a binding power value of the outmost coil layer of the bobbin coil (5). Through results of coil binding power testing, heating temperature and heating time in heat bonding process parameters can be adjusted, and therefore binding power values of bobbin coils can be quantified and controlled.

Description

technical field [0001] The invention relates to a tool and method for testing the bonding force of a skeleton coil. Background technique [0002] At present, more and more fly-by-wire flight control systems are used in the aviation field to control the flight of aircraft. Electromagnetic sensors, motors, transformers, solenoid valves and other components containing various electromagnetic components are an important part of the system feedback. Generally, the coils inside these parts can be made of ordinary enameled wires. After processing, they will go through processes such as pre-baking, dipping, dripping, and drying. It takes several hours or even dozens of hours of work. Produces pungent, noxious gas. With the continuous development of my country's basic industry, a self-adhesive enameled wire coated with self-adhesive paint has attracted the attention of the aviation manufacturing industry and has been gradually introduced. At present, the self-adhesive enameled wire...
