A process device for grinding piston head circular groove quenching surface of the locomotive diesel engine is modified by adopting the common lathe, and relative rotating movement is produced between a workpiece and the grinding wheel by the drive of the motor so as to finish grinding work. The piston head circular groove quenching surface grinding device of the locomotive diesel engine belongs to process equipment with simple structure, reliable work and low cost, provides conditions for realizing application and popularization of advanced process technology of 'laser quenching + grinding processing' of a piston head circular groove, remarkably improves processing quality of a piston head circular groove quenching surface of the locomotive diesel engine and the service life of a piston head, and has practical value.
Description
Technical field the utility model relates to a kind of piston head ring groove mill turning device of the C620 of utilization repacking of ordinary lathe.
During the work of background technology diesel engine piston, the side up and down of annular groove and piston ring produce impact wear, and fit clearance is strengthened, and sealing property degenerates, the adverse consequences that this will cause, and fuel economy is bad, dynamic property reduces.The piston head annular groove adopts " turning processing+salt-bath nitriding " technology at present, thereby realizes that piston head ring groove surface hardness, machining accuracy are to improve the purpose of wearability.The remarkable shortcoming of this kind processing technology is: 1 nitration case approaches, wears no resistance, because nitrogenize hardness thinner thickness (0.25-0.30mm), so ring groove surface wears no resistance under condition of work; 2 surface roughness values are big, piston head ring groove surface roughness value is about Ra3.2 during turning, because surface roughness value is bigger, make ring groove surface contact-making surface under actual operating conditions produce the failure by shear between plastic deformation, strain and the peak portion, cause heavy wear; The 3 annular groove dimensional accuracies and the accuracy of form and position are lower, because the turning operation is to machine before the salt-bath nitriding heat treatment step, therefore the distortion of salt-bath nitriding generation directly has influence on the piston head finished product accuracy, former piston head annular groove scale error 0.01-0.015mm, annular groove is working surface parallelism error 0.005-0.010mm up and down.
The summary of the invention the purpose of this utility model is to overcome weak point in the prior art, changing " turning processing+salt-bath nitriding " technology is " laser quenching+grinding " technology, for the processing of piston head of diesel engine annular groove provides a kind of piston head ring groove mill turning device that utilizes repacking of ordinary lathe.This structure of the piston head ring groove mill turning device of repacking of ordinary lathe of utilizing is: the engine lathe main shaft is equipped with the piston head positioning clamping device of fixation workpiece; Threephase asynchronous and ring groove mill head unit are installed on this engine lathe middle carriage, and threephase asynchronous connects by adjustable electric motivation damping supporting device and lathe middle carriage; The belt pulley of motor main shaft rotates by the belt pulley that belt drives the ring groove mill head unit.The ring groove mill head unit is provided with armature spindle, and armature spindle is installed in the ring groove mill head unit axle sleeve by rolling bearing, and two ends, the armature spindle left and right sides are equipped with emery wheel and belt pulley respectively.But ring groove mill head unit corner ± 5 ° in horizontal plane.Belt adopts the safety guard protective device.The ring groove mill head unit adopts the rolling bearing structure of rear and front end high accuracy adjustable clearance.
This technological equipment that utilizes the C620 engine lathe to implement the grinding of piston head annular groove, the technological equipment of piston head annular groove grinding is installed on the middle carriage of C620 engine lathe, can realize laterally the feeding of (X to) and vertical (Z to) two directions.Threephase asynchronous (1400 rev/mins of model Y90S-4 rotating speeds) is to connect by adjustable motor damping supporting device and lathe middle carriage, at utmost reducing the vibration of motor, and can realize the adjustment of motor in horizontal all directions.The threephase asynchronous that is installed on the middle carriage drives the bistrique rotor main shaft by belt transmission, and reduces the influence of motor oscillating to grinding.The bistrique rotor main shaft is installed in the ring groove mill head unit axle sleeve by 4 rolling bearings (model 7206C), adopts the grease lubrication bearing, and the rear and front end can be adjusted the bearing clearance, front and back end respectively.Work piece positioning is installed on machine tool chief axis tightly installs, the piston head clamping positioning clamping device on, slowly run clockwise with the lathe main shaft.Emery wheel (white fused alumina parallel grinding wheel P125 * 20 * 32) is high speed rotary grinding piston head annular groove counterclockwise, adopts cooling fluid that grinding skin is lubricated in the grinding process and cools off.
The utility model provides a kind of simple in structure for the grinding of diesel engine of locomotive piston head annular groove hardened face, reliable operation, technological equipment with low cost, promote the condition that provides for realizing piston head annular groove " laser quenching+grinding " advanced technologies The Application of Technology, significantly improve the service life of diesel engine of locomotive piston head annular groove hardened face crudy and piston head, possess practical value.
Adopt the process unit of the annular groove grinding that this patent provided to have following advantage: 1 equips by grinding process, can realize piston head annular groove " laser quenching+grinding " technology, the ring groove surface quench-hardened case can be brought up to 0.50-0.55mm, and wearability significantly improves; 2 surface roughness values obviously improve, and adopt grinding process to substitute turning processing, and the ring groove surface roughness value is reached between Ra1.6～Ra0.8; 3 annular groove precision significantly improve, because grinding is carried out after laser quenching, can effectively eliminate the distortion that produces because of laser quenching, grinding can reach the precision of IT4 level in addition, therefore piston head annular groove finished product accuracy can reach: scale error is below 0.008mm, and the working surface parallelism error is below 0.005mm about the annular groove.
