Complex shell structure with oil ways

Abstract

The invention relates to mechanical hydraulic control system components, in particular to a complex shell structure with oil ways. The complex shell structure is characterized in that the diameter ofthe oil ways is smaller than or equal to 6 mm, at least one oil way needing to be in turning communication is arranged in a shell, a switching device is arranged on the oil ways, the switching deviceis located in the shell and is composed of cylinders, and the diameters of the cylinders are larger than 6 mm, a communication structure is machined on the switching device, and the oil ways are located in a two-dimensional plane of a three-dimensional coordinate system of the shell. According to the complex shell structure, the switching device is arranged on the oil ways of the complex shell, sothat the communication diameter of the oil ways is effectively increased, and communication of the oil ways is facilitated; through an annular groove which is formed in the shell, it is guaranteed that the oil ways are located in the two-dimensional plane of the three-dimensional coordinate system of the shell, so that the shell is more compact in design; and the complex shell structure can effectively solve the problems of design and oil way layout so that the shell can be conveniently machined, and the design quality and the machining percent of pass of the shell are improved.

Description

technical field [0001] The invention relates to mechanical hydraulic control system components, in particular to a complex shell structure designed with oil passages. Background technique [0002] In a mechanical hydraulic control system, a complex housing with internal oil circuits is an important component. Such as figure 1 , The existing complex shell with internal oil circuit is made up of shell 1, plug 2, plug 3, plug 4, plug 5, plug 6 and plug 7. There are six oil passages inside the shell, among which oil passage a is connected with oil passage b, oil passage d and oil passage e, and oil passage c is connected with oil passage f. Plug 2, plug 3, plug 4, plug 5, plug 6 and plug 7 are respectively assembled on the casing oil passage e, oil passage f, oil passage a, oil passage b, oil passage c and oil passage d the outer end of the hole. [0003] The existing casing has an irregular shape and a complex internal structure. The casing blank is obtained through a casti...

AI Technical Summary

Problems solved by technology

[0003] The existing shell has an irregular shape and complex internal structure. The shell blank is obtained through the casting process, and then a number of oil passage holes and other parts that need to be processed are processed by machining.

The shell is complex and the internal structure has many restrictions, resulting in the oil passage holes of the shell being mostly three-dimensional space oil passages

When the diameter of the oil passage is less than or equal to 6mm, it is difficult to communicate between the processed oil passages

[0004] The shell design of this oil circuit connection method is difficult and the structure is complex. There are six three-dimensional space oil circuits inside, or more two-dimensional plane oil circuits, and the layout of the oil circuit is difficult; the processing of the shell oil circuit is difficult, and there may be The casing steering oil circuit cannot be connected, resulting in waste of the casing
