Description

Driving coil structure, winding mold, and winding process This application relates to the technical field of vibration testing equipment, for example, to a driving coil structure, a winding mold, and a winding process. The present disclosure claims priority to a Chinese patent application with application number 202211034824.1 filed with the Chinese Intellectual Property Office on August 26, 2022, the entire contents of which are incorporated by reference into the present application. In the related technology, compared to a conventional vibration table, the drive coil of an induction vibration table is divided into an inner drive coil and an outer drive coil. While the inner drive coil can be wound using the original vibration equipment, the outer drive coil must be wound by winding the coil body inside the outer coil frame, and the coil body and the outer coil frame must be bonded and cured using an adhesive to connect them as a single unit. Related technology CN108183023 discloses a driving coil winding process. As our country's industry and science and technology advance, induction vibrating tables are becoming increasingly widespread, and the demand for them is rising. Large induction vibrating tables require high thrust, high acceleration, and relatively high operating temperatures; however, the overall strength of the drive coil structure manufactured by the aforementioned drive coil winding process is relatively low, which prevents them from meeting the requirements for long-term operation. Therefore, this issue must be urgently addressed. FIG. 1 is a schematic cross-sectional view of a driving coil structure according to an embodiment of the present application. FIG. 2 is a schematic diagram of the structure of a coil body wound with a single wire according to an embodiment of the present application. FIG. 3 is a schematic diagram of the structure of a coil body wound with a double wire according to an embodiment of the present application. FIG. 4 is a schematic diagram of the overall structure of an external coil frame according to an embodiment of the present application. FIG. 5 is an overall structural schematic diagram of a driving coil winding mold according to an embodiment of the present application. FIG. 6 is a schematic cross-sectional view of a driving coil structure and a driving coil winding mold according to an embodiment of the present application.
