In the decades of medical work, we have found that many mechanical control parts of medical devices use pneumatic cylinders or hydraulic (oil) pressure cylinders. These two types of “cylinder” often cause leakage of pneumatic cylinders and leakage of hydraulic cylinders during clinical use. Oil, it is more difficult to overcome the above problems for a long time, electrical cylinders will not appear the above problems. In 1989, we used single-phase electric cylinders in our own medical devices for the first time in scientific research projects. We later designed two scientific research results with electric cylinders. All of them are very successful, and they are flexible, convenient, simple, and cost-effective. less.
In order to make the medical industry's counterparts better understand the electric cylinder, the following describes its principle and industrial applications, so that everyone can do its best to develop the application of electric cylinders in medical devices. The “cylinder” referred to here is often a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder. They convert a linear reciprocating motion into a number of complicated motion machines.
The electric cylinder can be used for long-distance operation, and can also be controlled by an automatic control system. Compared with pneumatic cylinders and hydraulic cylinders, it is not as bulky and complicated as pneumatic cylinders and hydraulic cylinders; it is also not like “pneumatic cylinders” and “hydraulic cylinders”. It is easy to leak and leak oil, causing environmental pollution; and electric cylinder also has reliable performance, sensitive action, smooth, accurate thrust, easy installation, maintenance, overload protection, limit protection device, so a wide range of applications, so The electric cylinder is a kind of auxiliary equipment with high economic benefits.
Working principle: After the motor decelerates through a pair of gears, it drives a pair of screw nuts to convert the rotational motion of the motor into a linear motion, and completes the push-pull action using the forward and reverse rotation of the motor. For example, through various mechanical structures such as levers, rockers, and connecting rods, it is possible to complete complex actions such as turning and shaking. By changing the length of the lever arm, it is possible to increase or increase the stroke.
