Cylinder housing pump pressure tooling

Abstract

The invention discloses a pumping pressure tool for a cylinder barrel shell and belongs to the field of tools. The pumping pressure tool comprises a front end cover, a rear end cover and a cylindricalmain body structure. The front end cover is provided with an exhaust hole and a screw plug matched with the exhaust hole, an oil injection hole is formed in the rear end cover, and the front end cover and the rear end cover are connected through the cylindrical main body structure. When the cylindrical main body structure is sleeved with the cylinder barrel shell and the two ends of the cylinderbarrel shell are connected with the front end cover and the rear end cover in a covered mode, an annular cavity is formed between the cylinder barrel shell, the cylindrical main body structure, the front end cover and the rear end cover, and thus the cylinder barrel shell can be subjected to pumping pressure testing.

Description

technical field [0001] The invention relates to the field of tooling, in particular to a cylinder shell pumping tooling. Background technique [0002] The cylinder shell is the main body of the hydraulic cylinder, and its main function is to form a closed oil chamber with the piston and the seal. Because during the working process of the hydraulic cylinder, the cylinder shell is subjected to a large pressure of hydraulic oil, so in the process of making the hydraulic cylinder, it is necessary to carry out a pressure test on the cylinder shell. [0003] The existing pressure test is realized according to the following method: the inner cavity of the cylinder shell to be tested is formed into a closed space through the pump pressure tooling, and hydraulic oil is injected into the closed space to make the pressure in the inner cavity of the cylinder shell reach a predetermined value, and then the pressure is maintained for a period of time. Time, check whether there is leakage...

Problems solved by technology

[0006] In order to solve the problem in the prior art, for the cylinder shell with working pressure in a high-pressure environment, the pump pressure tooling is also subjected to a large pressure during the pressure test, which makes it difficult for the general pump pressure tooling to be suitable for the cylinder tube in a high-pressure environment. For the pressure test of the shell, the embodiment of the present invention provides a cylinder shell pump pressure tooling, the technical solution is as follows:
