Problems solved by technology
The loosely coupled transformer used in rotary ultrasonic machining is different from the traditional transformer. The air gap between the primary and secondary sides will increase the leakage inductance of the transformer. It is necessary to design a compensation circuit to improve the transmission efficiency. Secondly, the special magnetic core structure also makes it impossible to operate according to the current situation. Some general transformer design specifications for design
In addition, in the actual application process, it is often necessary to replace a variety of ultrasonic tools according to the processing technology. It is unrealistic to equip each ultrasonic tool with a separate set of circuit compensation and loosely coupled transformers, which will greatly increase the difficulty of automatic tool change on machine tools.

Embodiment Construction
[0030] Below in conjunction with accompanying drawing and case the present invention is described in further detail:
[0031] like figure 1 , figure 2 and image 3 As shown, a combined loosely coupled transformer is composed of a primary side magnetic core 4 and a secondary side magnetic core 1 . The secondary magnetic core has a complete ring shape, the central through hole 2 is used to assemble the ultrasonic tool, and there is a circle of annular grooves on the side for filling the secondary coil. The main side magnetic core is assembled on the machine tool and is composed of a plurality of magnetically permeable material sheets 5 ( figure 1 The middle is 8 pieces), the output power and power transmission efficiency can be adjusted by increasing or decreasing the number of slices to change the core angle α to adjust the output power and power transmission efficiency to adapt to a variety of ultrasonic tools. The main side magnetic core groove 7 is used to fill the main ...

The invention relates to a structure of an electric energy transmission device and a parameter optimization design method thereof. The combined loosely coupled transformer in the present invention is composed of a primary magnetic core and a secondary magnetic core, wherein the primary magnetic core is composed of multiple sheets of magnetically permeable material, and the secondary coil is in the form of a coil plate. The optimal design method in the present invention is to establish the reluctance model and the mutual inductance model of the combined loosely coupled transformer, establish the mapping relationship between the transformer structural parameters and compensation parameters and the transmission efficiency and output power of the ultrasonic transducer, and finally through the genetic algorithm for optimization. The invention can realize a set of circuit compensation and dynamically adjust the core angle of the main side and the number of layers of the coil plate of the secondary side of the combined loosely coupled transformer, so as to adapt to various ultrasonic tools, effectively reduce the processing cost and the difficulty of machine tool change, and improve the processing efficiency and power utilization.
