Problems solved by technology
The traditional press-fit method is to directly align the valve guide with the valve hole and press it in with an oil cylinder. It is impossible to know the size of the press-in force, and it is easy to cause leakage or too tight fracturing of the cylinder, and the valve guide can only rely on its own guide to press in and it is easy to be biased. Scrapping and low production efficiency

The invention discloses a cylinder valve guide press-fitting machine, which comprises a base, on which a tool for pressing the guide tube is arranged, a support frame is arranged on the base, and an oil cylinder for press-fitting is arranged on the top of the support frame and above the tool for pressing the guide tube; The end of the front push rod of the oil cylinder is connected from top to bottom with a connecting rod, a pressure sensor, a press fitting guide rod and a pressure head; Cylinder hole positioning fits the boss, and the positioning seat is provided with an elastic guide rod assembly corresponding to the valve hole of the cylinder to be pressed. The upper end of the elastic guide rod assembly extends out of the positioning seat and is slidably connected with the valve hole of the cylinder to be pressed. The press-fitting machine of the present invention can ensure that the valve guide is quickly and smoothly pressed into the valve hole of the cylinder under the action of the elastic guide rod assembly, and can ensure that the pressure is within the specified range. When the pressure exceeds the specified range, it will alarm and stop, avoiding Too loose or too tight due to improper fit tolerance of valve guide.
Description
technical field [0001] The invention relates to the field of mechanical processing, in particular to a cylinder valve guide press-fitting machine. Background technique [0002] The cylinder pressure valve guide requires that the supporting surfaces of the two valve guides are completely in contact with the upper surface of the valve, there must be no burrs after press fitting, and the pressure must reach the specified range. After press-fitting, the cylinder must not leak for 5 seconds under the test pressure of 70KpA. The traditional press-fit method is to directly align the valve guide with the valve hole and press it in with an oil cylinder. It is impossible to know the size of the press-in force, and it is easy to cause leakage or too tight to fracture the cylinder, and the valve guide can only rely on its own guide to press in and it is easy to be biased. Scrapping occurs and production efficiency is low. Contents of the invention [0003] In order to solve the defi...
