Description

Technical Field

[0001] This utility model relates to the field of sawing device technology, and in particular to a sawing rotary device. Background Technology

[0002] In the machining, hardware manufacturing, and woodworking industries, material sawing is a crucial basic process. Traditional manual sawing relies mainly on operators manually adjusting the workpiece angle and controlling the sawing process. Manual operation makes it difficult to precisely control the sawing angle, resulting in large workpiece dimensional deviations, high surface roughness, low product qualification rates, and significant material waste. At the same time, operators need to frequently bend over and raise their hands, which is labor-intensive and inefficient, limiting the daily processing capacity and making it difficult to meet the needs of large-scale production. Furthermore, during manual operation, the saw blade is exposed, and operators' hands are easily accessible to the cutting area, posing safety hazards such as cuts and abrasions. Therefore, most industries currently use automated sawing devices to cut materials.

[0003] Most existing sawing devices use ordinary motors to drive a turntable in conjunction with mechanical limit structures to achieve angle adjustment. However, such devices have obvious drawbacks: the angle adjustment range is limited, and they can usually only achieve angle cutting within a certain range, which cannot meet the arbitrary angle processing requirements of complex workpieces. At the same time, the open-loop control method of ordinary motors lacks precise positioning capabilities, and when combined with gear or belt drives, transmission gaps are easily generated, resulting in large errors in the rotation and positioning of the saw blade, making it difficult to meet high-precision processing requirements. Furthermore, the transmission system is not stable enough during high-speed sawing, and motor vibration and mechanical impact can easily cause saw blade shaking, which not only affects the surface accuracy of the processed surface but also accelerates tool wear and shortens the service life of the equipment.
