Introduction

In lathes, instead of a layout with a separate arrangement of the spindle and gearbox, they began to use a gearbox with a spindle. This situation is due to the fact that in this case the drive becomes more compact, the number of body parts decreases, the total error at the end of the spindle decreases, and it is easy to control and operate.

In this course design, the drive of the main movement of the multi-purpose machine, which is a gearbox with a spindle, is being developed. For this purpose, the design of the machined parts is analyzed, the manufacturing technology of the detail representative is specified, the main technical characteristics of the module, the machine layout, functional subsystems are determined and the structure of the module is developed. The module parts are calculated using computers, the module design is developed and the calculation and graphics part is executed.

Conclusion

During the course work, elements of the sketch and technical design of the module of the main movement of the machine with numerical program control were developed. The technological purpose of the machine, the main functional subsystems of the module and its structure, the layout of the machine and the module were determined, the kinematic diagram of the module was developed. This module is designed to process parts of the piston type, all main surfaces have been taken into account in the design, which may include parts of this type.
