Description

technical field [0001] The invention relates to the field of detection equipment and technology, in particular to a detection device for adjusting the eccentricity of a piston rod. Background technique [0002] Piston structures are often used in daily life, such as medical syringes, automobile engines, a large number of hydraulic cylinders and pneumatic cylinders, etc. The use of piston structures brings people a very convenient experience, but the piston rod During the long-term use, the problem of eccentricity may be caused by damage and other reasons. If the problem of eccentricity cannot be dealt with in time, it may cause very serious losses. And different piston rod detection methods are also different. [0003] Although the current detection methods have realized the problem of detecting the eccentricity of the piston rod, for example: Chinese utility model patent specification: CN201921414746.1 discloses a cylinder piston rod fatigue test device, which includes a b...

[0002] Piston structures are often used in daily life, such as medical syringes, automobile engines, a large number of hydraulic cylinders and pneumatic cylinders, etc. The use of piston structures brings people a very convenient experience, but the piston rod During the long-term use, the problem of eccentricity may be caused by damage and other reasons. If the eccentricity and other problems cannot be dealt with in time, it may cause very serious losses. And different piston rod detection methods are also different

[0003] Although the current detection methods have realized the problem of detecting the eccentricity of the piston rod, for example: Chinese utility model patent specification: CN201921414746.1 discloses a cylinder piston rod fatigue test device, which includes a bearing mechanism for fixing the cylinder, and the bearing mechanism The lower part is connected with a connecting rod, and the other end of the connecting rod is connected with the rotating disk. The rotating disk is provided with an eccentric adjustment mechanism. The sensor, the other end of the sensor is connected with a pressure plate, and the pressure plate is connected with a space adjustment rod. This device improves the connection mode of the sensor, and sets the fatigue stroke structure as an adjustable type, which prolongs the service life of the device and increases the versatility of the device. The device uses The traditional sensor method is used for detection, but it does not have too many excellent performances for the adjustment method, and the test device cannot solve the connecting rod piston structure, and the merger does not have a good performance effect
