Introduction

The creation and implementation of special and specialized machines and automatic lines for specific types of products is used to increase the productivity and quality of products produced over a long period in mass and large-scale production. Transferring such high-performance complex machines and automatic lines to the production of new products is either impossible or very limited.

Intensive development of the most advanced fields of technology causes frequent product renewal. Recently, almost all over the world there have been trends to increase the variety of products produced and reduce serial production. Currently, CNC process equipment is combined into single production complexes using transport and control systems. These complexes are called GPS. Flexible production and full integration of computer-based management open the way to the introduction of a more progressive organization of production, that is, the implementation of the production process and the supply of each part at a strictly set time, dictated by the pace of production of assembly complexes and products as a whole. This concept is applied by more than one enterprise, and it is connected into a single system of management of several sectors of the economy.

The industrial robot in the robotic process complex must perform auxiliary functions, and in the robotic production complex it performs the main operations of the technological process (assembly, welding, painting, etc.)

The purpose of the course project is to deepen and consolidate the obtained, to instill the skills and skills of engineering labor in the design of robotic systems and flexible automated systems.

Selection of PTK layout

RTAs used in metalworking can have different types of layouts.

This degree project will use a circular layout. The robot and the machine are arranged so that the working area of the machine is located in the service area of ​ ​ the robot, the dimensions of which are determined by the minimum and maximum flight of the hand.

The circular arrangement of the RTC gives easy loading and unloading of equipment, unhindered movement of the picking device of the PR. It reduces the auxiliary time for fixing and installing the workpiece, which allows you to reduce piece-costing time and, therefore, increase productivity.

The RTC in this project has a combined inlet and outlet, therefore, with such an arrangement, one chain conveyor is installed, which provides for the supply of blanks to the RTC and the reception of processed parts.

Thus, the circular arrangement of RTK gives:

1. unimpeded movement of FR gripper;

2. possibility of arrangement of equipment taking into account convenience of approach to it by operator or adjustment unit;

3. equipment is located around the robot, which leads to saving of production area;

4. the circular arrangement of the RTC gives a very high positioning accuracy of a very high positioning accuracy ± 0.02mm.

Conclusion

As a result of the development of this project, a complete study of the technological process of obtaining a part in medium-term production conditions was carried out. The most important stage of technology design is the purpose of the routing processing process, the selection of equipment, cutting tool and control devices.

Analysis of the linear and circular layout showed that for this RTC the most satisfying for all operating conditions is a circular type layout diagram. It allows the PR to move when feeding the workpiece from the clock table to the machine and back with greater accuracy. The cycle time can be reduced due to rationally assigned cutting modes.
