The utility model discloses a curved surface machining milling cutter structure which comprises a cutter body, a cutter tooth structure is assembled below the cutter body in an inserted mode, the cutter tooth structure is composed of a positioning cutter head, a connecting block and cutter teeth, the positioning cutter head, the connecting block and the cutter teeth are sequentially arranged from top to bottom, and the positioning cutter head and the cutter teeth are fixedly connected with the upper end face and the lower end face of the connecting block respectively. A positioning pin is integrally formed at the top end of the cutter tooth structure, a positioning pin hole is formed in the lower end of the cutter body, the positioning pin is assembled in the positioning pin hole in an inserted mode, a bolt set is fixedly connected between the cutter tooth structure and the cutter body, and a dismounting marking rod is connected to the upper portion of the cutter body in an inserted mode. According to the curved surface machining milling cutter structure, the split type design is adopted, the cutter body and the cutter teeth can be independently disassembled and assembled, the subsequent process of repairing or replacing the curved surface machining milling cutter is simplified, the convenience of repairing or replacing the curved surface machining milling cutter is improved, meanwhile, the cutter body can be repeatedly used, and resource waste is reduced.

The invention relates to the technical field of conference transmission, and provides a digital network conference transmission method, a conference host and a conference system, the method is applied to the conference host, and the method comprises the following steps: responding to various types of function cards, inserting the function cards into card slots, converting function signals of the function cards into network signals through built-in network chips of the function cards, and sending the network signals to the conference host; a network signal is transmitted to the field programmable logic gate array module of the conference host through the switch chip integrated by the card slot, so that the extension of corresponding functions is realized; a network signal of an audio type is transmitted to a digital-to-analog conversion chip on a digital-to-analog conversion decoding circuit of the conference host through an audio bus between integrated circuits via the field programmable logic gate array module for decoding; and the network signal of the control type is transmitted to the cooperative control module of the conference host for processing through the field programmable logic gate array module and a serial port. According to the embodiment of the invention, functions needing to be expanded can be realized, diversified conference requirements are met, and the flexibility and practicability of the conference host are improved.
