Abstract

This design takes the special cnc workbench and the control system design as the topic，designs a cnc workbench，the workbench has one moving shaft and one turning shaft，the two axes have the linkage function。the workbench is installed on the ordinary vertical milling machine，which is used to process the type surface of the disc-shaped cam. The rotary table transposition cam device。including the drive shaft。the matrix，the transposition section and the positioning block，the positioning block is mounted on the matrix，the matrix is mounted on the transmission shaft，and the transposition section and the matrix are integrated structure. By using the positioning block and the matrix and transposition section as the component structure，it can make the machining become simple，and the cam which meets the precision requirement can be processed with the common equipment instead of the expensive multi-axis machining centers as well as coordinate grinders for the precision processing of curves；its maximum machining diameter 500mm。maximum machining thickness 150mm，machining precision ±0.01mm，and roughness 3.2m；meanwhile。it has the advantages of easy assembly and replaceable after wear，which greatly reduces the manufacturing cost and solves the very complex manufacturing problems with the simplest method.

According to the technical requirements of the workbench in the graduation design task book，draw up the mechanical transmission scheme of the workbench，complete the design and calculation of the key parts of the machinery，draw the assembly drawing and part of the part drawing，complete the design of the NC system controlled by MCS-51 single chip microcomputer，and draw the schematic diagram of the control system. At the same time according to the mechanical part design calculation，motor and key parts selection calculation，control system chip selection，NC system electrical schematic drawing.

Keywords: cam；numerical control；rotary table；control system；schematic diagram
