Irregular stone multifunctional composite processing center with double five-axle linkage system

Abstract

The invention relates to a special shaped stone high-speed high-efficiency combined machining center with the functions of double five-axis linkage and synchronous cutting by double working heads, and relates to a device for processing stones. Active gantry structure is adopted in the machining center, the double-motor synchronous driving technology is adopted on the gantry beam, and synchronous high-speed driving is realized by the screw bar pair at the two sides; a milling working head component and a turning working head component are respectively arranged on the saddle of the beam, the vertical feeding mechanism thereof is formed by a suit of screw bar pair and a hydraulic pressure auxiliary mechanism; wherein, the milling working head can carry out rotation and scales division aroundthe axis B, and the turning working head facilitates the same servo motor to realize rotation and scale division of axis A and cutting movement; the turning working head and the milling working head are arranged alternately, and both the turning process and the grinding processing can be carried out on stone articles at the same time. The machining center is provided with a numerical control system with the function of double five-axis linkage, and horizontal five-axis linkage machining and vertical five-axis linkage machining can be realized.

Description

technical field [0001] The invention relates to a stone processing equipment, in particular to a special-shaped stone high-speed and high-efficiency composite machining center with double five-axis linkage function and double working head synchronous cutting function, which can realize the processing of various shapes of stone such as horizontal and vertical Processing: It can complete various forms of processing such as turning, milling, grinding, carving, sawing, etc. of stone products. Background technique [0002] Natural stone has been an excellent building material since ancient times due to its good texture, solemn appearance, good mechanical and physical and chemical properties (such as pressure resistance, wear resistance and corrosion resistance). With the development opportunities brought by reform and opening up, my country has become a veritable "stone processing factory" in the world. Compared with the rapid development of the stone industry, the development o...

[0004] 2. The processing efficiency of the equipment is low

The factors that restrict the efficiency of stone processing are mainly manifested in the following aspects: First, the processing of stone products usually goes through multiple processes such as contour processing, rough processing, finishing, polishing and grinding processing. The current processing technology is through different equipment. It is not only time-consuming and labor-intensive, but also difficult to guarantee the required processing accuracy, especially the polishing and grinding processing is still mainly manual processing, the production efficiency is very low and the processing cost is high; secondly, the domestic gantry processing equipment mainly For stone processing equipment, most of the beams use the same servo motor to make the rack and pinion pairs on both sides move synchronously through a shaft passing through the bottom of the beam. The feed speed is low and the feed accuracy is not high; third, relatively As far as foreign equipment adopts multi-head synchronous processing and high-speed processing technology, domestic multi-head synchronous high-speed and efficient processing equipment is still blank

[0005] 3. The processing quality of the product is not high

At the same time, stone products have high requirements for gloss and relatively low requirements for dimensional accuracy of products. Therefore, using metal processing machine tools or machining centers to complete the processing of stone products will not only cause certain damage to the machine tool itself, but also difficult to achieve the corresponding Machining accuracy requirements
