Problems solved by technology

[0002] In the swing actuators of the existing disclosed pneumatic angular stroke, one of them is to convert the straight motion of the cylinder or film air bag into an angular stroke through the rack and pinion mechanism or the pin shaft mechanism, so the result is complicated; The intensity of the stress presents a high-level transmission from small to large, and the rack gear or pin shaft, which is the highest stress-bearing part, becomes the weak link that affects the life; The use space of non-executive power action is reduced, and the compressed air is wasted in action switching; due to the high processing precision of parts and different shapes, the manufacturing cost is relatively large; the volume of parts is also large; due to the large stress Many parts are basically made of metal materials, and the weight of the swing actuator is also relatively large, while the anti-corrosion performance of metal materials is significantly lower than that of organic composite materials

[0003] There are centrifugal pumps, plunger pumps and piston compressors in the existing disclosed pressure-feeding fluid machines. The stress intensity occurring in the dynamic process presents a high-level transmission from small to large. As the highest stress-bearing parts, cranks, connecting rods, and pins become weak links that affect life. Due to the need to meet the strength requirements of large peak stress , many parts are basically made of metal materials, and the anti-corrosion performance of metal materials is significantly lower than that of organic composite materials; these mechanical parts have many types, complex structures, high costs, and low mechanical work efficiency

In the existing public information, we have not found any similar information about the piston swing drive machine for the clip swing tray
