Description
The utility model is a kind of equipment that is used for automatic turning camber variable ellipse piston.
Existing oval piston process equipment; the Sl-240B profiling type oval piston automatic lathe of domestic production no matter; or profiling formula from external introduction; profiling type oval piston automatic lathe all is equipped with pattern or profile mould, adds man-hour because of pattern or paranorm are arranged; therefore cause that vibration force is big; phenomenons such as track departs from, lags appear in serious wear, make the product precise decreasing.
The purpose of this utility model provides a kind of no pattern, and vibration force is little, and it is little, easy to use to wear and tear, and the life-span is long, the fixed shaft type automatic turning oval piston equipment that the product precision is high.
Automatic turning oval piston equipment of the present utility model is dwindled several parts such as mechanism, fixed shaft type ellipse generator, digital control system and forms by bed body, motor, rotary error.
The fixed shaft type ellipse generator is made up of gear train, universal joint, splined shaft and roller knife bar parallel moving mechanism.Elliptical orbit is by two compound realizations of the circular motion that rotates in fixed axis.Wherein, workpiece is with W
1Angular speed on main shaft, rotate.Dwindle mechanism by rotary error, roller knife bar parallel moving mechanism makes the point of a knife that is fixed on the translation knife rest with W
2Angular speed and workpiece rotate in the same way, and make W
2=2W
1, then the point of a knife track of getting on the bus out at workpiece is exactly a standard ellipse.The fixed shaft type ellipse generator has replaced pattern and profile mould in the past, has fundamentally solved serious wear, the problem that vibration force is big and track lags.Rotary error is dwindled mechanism, and the relation that proportion of utilization dwindles can make error dwindle about 100 times, thereby improves machining accuracy greatly, dwindles mechanism and is made up of two rotating shafts, a sliding support, three bearings.When rotating shaft is done the dead axle rotation,, utilize balancing act to reduce vibration force because of centrifugal inertial force is a constant.Digital control system is made up of TP-801A single board computer, interface circuit, driving power.Displacement with three stepper motors realizations of software program control X, Y, three directions of Z changes the variation of ovality and piston bus.Roller knife bar parallel moving mechanism is made up of slide plate, retainer, roller, translation knife rest.When workpiece on main shaft with W
1Angular speed when rotating, be installed in the point of a knife on the translation knife rest, by the rectilinear motion of two orthogonal slide plates, compound is circular motion.By the rotary control of dwindling mechanism and digital control system, point of a knife is with W
2Angular speed and main shaft on W
1The angular speed workpiece rotate in the same way, car goes out high accuracy standard ellipse piston.
