Research On CNC Horizontal Mortor Base Boring Machine

As a national key industry,the motor industry plays a decisive role in national defense,automobile and machine tool industries.However,the machining of motor bases for large motors becomes a key technology.In our country,without the CNC motor base boring machine,it has been using a special machine to process the motor base,so it is characterized by the need to re-install multiple fixtures,led to low efficiency,low accuracy,labor intensity,and could not mass production.In order to overcome the above shortcomings,our factory produces such a motor base boring machine according to the technical reserve of the milling and boring machine and the production capacity.The boring diameter and depth can reach 3 meters.In order to meet the requirements of machine tool's function and main technical parameters,this thesis designs the motor-base drive system,feed system and static pressure system according to the structural characteristics and machining technological requirements of the motor-boring machine,combined with the main components of the machine tool and structural features.In the thesis,mechanics and kinematics theory analysis and calculation are also carried out for the main parts and components.At the same time,the finite element analysis of the important parts is carried out.The stiffness of the cantilever sleeve is analyzed.The static pressure system part of the workbench is analyzed theoretically Finally,according to the actual situation of the assembly,the precision test indexes are obtained.The precision indexes meet the requirements of the relevant national machine tools standards,which can ensure the operation of the CNC machine tools is stable,safe and reliable,and the accuracy is maintainable.Expected g oals,confirmed that the overall design of the machine tool and expected results to achieve the desired state,and better than other similar domestic products.The machine has the advantages of compact design,reasonable layout,humanized appearance design,elegant appearance and convenient operation.The good use effect obtained is mainly due to the rigidity of the cantilever sleeve of the spindle box,clip to complete the order processing accuracy requirements.Production efficiency has also been improved,and the machine is widely used in motor factory processing all kinds of AC,DC generator and motor base on the face and the hole and other products,have been good results and the desired accuracy,which is to improve the competitiveness of the company's products in the market.
