Introduction

Now it is difficult to imagine a modern industrial enterprise or design bureau without computers and special programs designed to develop design documents or design various products. The application of computer technology in this field has become a fait accompli, has proved its high efficiency. Life itself forces the heads of enterprises and specialists to deal with the automation of the work of design and technological units. The transition to machine design allows you to significantly reduce the time required to develop design and technological documentation and thereby accelerate the start of production of new products. At the same time, the quality of both the design development itself and the issued documentation is improved. Today, higher and secondary special educational institutions pay great attention to the use of computer technology in the training of students. Already within the framework of the university, students master the most promising design technologies, acquire skills in working with computer and machine graphics systems. The drop in computer prices has made a modern computer available for home use. This allows students to work with computer-aided design systems not only within classroom hours, but also on personal computers. In this case, we can talk not about superficial acquaintance with the subject, but about its real development.

Task setting:

According to the proposed general view drawing:

drawings of parts of the type: housing, connector, spring;

Solid model of incoming parts

solid assembly according to the proposed drawing;

Solid assembly with required sections

Application and principle of operation:

Hydraulic lock is a hydraulic controlled check valve used to close working cavities of hydraulic cylinders.

The principle of hydraulic lock operation is as follows. Suppose that the right hydraulic lock line is connected to the working cavity of the hydraulic cylinder, and the left one is connected to the rod cavity of the hydraulic cylinder. Then the oil under pressure going into the piston cavity through the channel of the connector will move the slide valve in the housing and open the left check valve, through which the oil from the rod cavity of the hydraulic cylinder will be drained. At the same time RH check valve is opened and oil is supplied through it to piston chamber of hydraulic cylinder. Upon termination of fluid access to hydraulic lock, slide valve returns to neutral position, and both check valves close under action of springs and oil pressure from the side of piston and rod cavities of hydraulic cylinder, fixing hydraulic cylinder piston in specified position.
