Novel air cylinder quality verification device

Abstract

The invention discloses a novel air cylinder quality verification device. The novel air cylinder quality verification device is composed of an air compressor, an air pipe and a verification platform frame. Three air cylinders can be simultaneously arranged on the verification platform frame. The air pipe is connected with reversing valves of the three air cylinders through an air pipe tee joint and an elbow. The direction of high pressure air entering the air cylinders is changed by controlling the reversing valves through an external control cabinet so that the air cylinders can drive air cylinder pull rods to reciprocate. In the movement process of the air cylinder pull rods, whether air leakage exists around the air cylinders or not is verified by observing the surface profiles of the air cylinders and the movement states of the air cylinder pull rods so as to judge whether the defects of surface quality problems, air leakage and the like exist in the air cylinders or not. When used for conducting air cylinder quality detection, the novel air cylinder quality verification device can externally complete verification of performance such as the stroke, the stability, the air tightness and the surface machining quality for the air cylinders through one-time installation, the process is simple and efficient, and meanwhile the novel air cylinder quality verification device is simple in structure and reliable, and allows installation blades of the air cylinders to be easily detached.

Description

technical field [0001] The invention relates to the field of mechanical equipment detection, in particular to a device for checking whether the quality of a cylinder is qualified. Background technique [0002] Cylinders are the most common actuators in pneumatic systems and are widely used in the field of industrial automation. Compared with motors, cylinders are better at performing reciprocating linear motion, especially suitable for the most common linear workpiece handling in industrial automation, and generally only need to adjust the intake pressure of the cylinder and the opening of the intake and exhaust valves. Realize stable speed control. However, due to quality problems such as unqualified assembly or damaged cylinder parts, the produced cylinders often have leakage problems. The leaked cylinders not only affect the use of the cylinders, but also cause a lot of waste of energy. There are following several types of cylinder quality inspection devices in the prio...
