A four-axis linkage CNC machining center and its working method

Abstract

The invention aims to provide a four-axis linkage type computer numerical control machining center and a working method thereof. According to the technical scheme, the four-axis linkage type computernumerical control machining center is composed of a machining cabin, a tool bearing frame, a tool controller, a tool changing machine, a tool changing control table, a machining control cabinet and amachining mechanism, wherein the machine mechanism is composed of a machining bearing table, a Y-axis moving rail table, a Y-axis moving frame, an X-axis moving supporting table, an X-axis moving railtable, a Z-axis machining mechanism, a telescopic machine and a plurality of material bearing fixing frames, and the machining bearing table is composed of a waste material collecting tank, a waste material overturning device and a waste material recovering plate. According to the four-axis linkage type computer numerical control machining center, tool changing operation and machining operation form two independent control units so that misoperation caused by a single control unit is avoided, maintenance and overhaul are facilitated, then four-axis linkage type computer numerical control machining is more accurate, material fixing and position adjusting can be realized through the plurality of material bearing fixing frames, waste materials obtained after machining can be concentrated, sothat the internal operation environment of a machining space is guaranteed, and the quality of machined products is improved.

In the long-term economic construction, China's machinery manufacturing industry has made remarkable achievements, but it is undeniable that it has also exposed some problems in the process of development. For any country, the level of machinery manufacturing industry will affect the China's economic construction has an important impact, and our country is no exception. The level of China's machinery manufacturing industry can reflect the overall level of China's economic construction to a certain extent. Therefore, it is no exaggeration to say that the machinery manufacturing industry provides an important guarantee for national development. At the same time, it is also one of the important criteria for judging the level of national construction; with the continuous development and progress of science and technology, some more efficient and smarter high-tech machining equipment is more and more favored and recognized by enterprises. Among them, four-axis linkage Machining center is a kind of high-end machining equipment commonly used in the control system of CNC milling machine or engraving machine. However, the working modes of the existing four-axis linkage machining centers on the market are similar, and they are only used to process and output parts. Although the advanced mechanical equipment is excellent in processing, it also exposes many problems. For example, the four-axis linkage tool needs to be replaced manually, which invisibly increases the risk, and it is easy to cause harm to the personal safety of the operator. Improper handling of waste materials leads to The working environment inside the machining center is harsh, it is not easy to clean the residual debris and it is easy to affect the operation of other parts inside the machining center, etc., and the fixing mode of the material to be processed is also very single, and the fixing device cannot be adjusted according to the model of the processed product The structure lacks the diversity of processing. In addition, the movement of the entire processing equipment and the transmission between each other are also limited, so that the processing accuracy cannot be guaranteed. It is necessary to conduct a comprehensive analysis and upgrade of the processing center to make The four-axis linkage processing operation is more accurate, and the fundamental problem is to solve and improve the lack of existing technical conditions
