Problems solved by technology

[0004] The present invention aims at the existing problems of replacing cylinder head seals and detecting whether the cylinder head seals are damaged or not, and provides a combined cylinder head with a built-in split gasket cover, which can effectively improve whether the dustproof ring and the sealing ring are High damage detection efficiency, when the oil cylinder leaks from the piston rod, it can be quickly judged by removing any one of the two symmetrical gasket sleeves, which is easy to operate and improves the efficiency of after-sales service

Embodiment Construction

[0015] Below in conjunction with accompanying drawing illustrate specific embodiment, as figure 1 Said, the combined cylinder head with built-in split gasket cover includes a cylinder cover (5) and a gasket cover (2), and it is characterized in that a gasket cover groove is opened at one end of the cylinder cover (5). The gasket cover (2) is installed in the gasket cover groove and connected by screws (3).

[0016] Such as figure 2 , Shown in 3, said is characterized in that the gasket sleeve (2) is a split structure, which is composed of two symmetrical gasket sleeves (2).

[0017] Such as figure 2 As shown, the sizes, tolerances, and surface roughness of all the grooves provided by the two symmetrical gasket sets (2) are exactly the same, and the inner side of the gasket sets (2) is sequentially provided with dust ring grooves (2-3), The first sealing ring groove (2-4), the second sealing ring groove (2-5), and the dustproof ring groove (2-3) are opened at the outer end...

Abstract

The invention relates to the field of hydraulic oil cylinders, in particular to a combined cylinder cover with a built-in separated gasket sleeve. The combined cylinder cover with the built-in separated gasket sleeve comprises a cylinder cover body and the gasket sleeve, and is characterized in that a gasket sleeve groove is formed in one end of the cylinder cover body; the gasket sleeve is of a separated structure and is formed by combining two eudipleural gasket sleeves; the gasket sleeve is installed in the gasket sleeve groove and is connected by adopting screws or double-screw bolts; andthe screws or the double-screw bolts are uniformly distributed on the excircle end face of the gasket sleeve. According to the combined cylinder cover with the built-in separated gasket sleeve, the efficiency on detecting whether a dustproof ring and a sealing ring are damaged or not can be effectively improved; and when a piston rod of an oil cylinder leaks oil, oil leakage can be quickly judgedby taking down any one of the two symmetrical gasket sleeves, so that the convenience in operation is realized, and the after-sales service efficiency is improved.

Description

technical field [0001] The invention relates to the field of hydraulic oil cylinders, in particular to a combined cylinder head with a built-in split gasket sleeve. Background technique [0002] During the use of the oil cylinder, external leakage is the most typical form of failure. During use, if the piston rod leaks oil, the most common way to deal with it is to use special tools to disassemble the oil cylinder from the machine, and then put it on The cylinder head is removed to determine whether the oil leakage of the piston rod is caused by the damage of the cylinder head sealing ring. The whole operation process is very complicated and the workload is heavy (for example, it takes at least two skilled workers to cooperate for half a day to disassemble the oil cylinder of the reloading machine arm) , especially when the sealing material has poor elasticity and the operator is unskilled or has no special tools, it is easy to cause the seal to be damaged during disassembly...
