Detailed description of the invention
Embodiment 1
As in figure 2 it is shown, this utility model grinding internal surface device, installing fast headstock 2 and emery wheel platform 3 on lathe 1, concrete structure is as follows:
Fast headstock 2 by the main shaft lower stage 4 being fixed on lathe 1, be assemblied in main shaft lower stage 4 and the spindle table 5 moved back and forth in X-direction (above-below direction in Fig. 2), be assemblied in spindle table 5 and the main shaft part 6 that can turn round in horizontal plane is constituted, spindle table 5 is connected with cutting servomotor 7, the driving of the spindle table 5 cutting servomotor 7 by being arranged in main shaft lower stage 4 so that it is position determines in Z-direction (left and right directions in Fig. 2) assigned position.In spindle table 5, the main shaft part 6 can independently turned round centered by fulcrum 8 is installed.Main shaft part 6 is connected with main shaft gyration servomotor 9, and the rotary position of main shaft part 6 can be adjusted by the driving of main shaft gyration servomotor 9.One end of main shaft part 6 is provided with chuck 10, the workpiece W of fixed cylindrical shape on chuck 10, and main shaft part 6 is turned round with workpiece W jointly by chuck 10.
Emery wheel platform 3 is made up of emery wheel playscript with stage directions body 11, stone platform 12, bistrique 13, on emery wheel playscript with stage directions body 11, stone platform 12 is set, bistrique 13 is fixed on stone platform 12, the fixed abrasive grinding wheel in front end 16 at the gyroaxis 15 extended out from bistrique 13, make abrasive grinding wheel 16 turn round by gyroaxis 15, the inner surface of workpiece W is carried out grinding and may also become.Stone platform 12 drives servomotor 14 to be connected with work surface, stone platform 12 drives the driving of servomotor 14 by work surface, in the range of emery wheel playscript with stage directions body 11, can move back and forth in Z-direction (left and right directions in Fig. 2) so that it is position determines the assigned position in Z-direction.
Cutting servomotor 7, main shaft gyration servomotor 9, workbench driving servomotor 14 are connected with control device respectively, and cutting servomotor 7, main shaft gyration servomotor 9, workbench drive the motors such as servomotor 14 to be driven control by the input signal carrying out self-control device.
The present embodiment grinding internal surface processing method, is carried out by the various engineerings of low precision grinding, high-precision grinding and no-spark cutting.Further, the incision feed speed of above-mentioned abrasive grinding wheel 16 is a definite value.In grinding, due to the bending of gyroaxis 15, the internal diameter of workpiece W can not become the biggest with cutting the amount of feeding, creates excision remnants.Owing to the sharpness of abrasive grinding wheel 16 is as the size variation of grinding wheel diameter, cutting residual volume is also change.Even in the dimensioned not using in-process gaging, cylindricity and the surface roughness of the inner surface of certain for the polish stock removal making reality as far as possible for workpiece W are stable, and cutting supplying position should be different according to the difference of the outside dimension of abrasive grinding wheel 16.During corase grind, incision supplying position can change along with the outside dimension of emery wheel 16 and change.
It is to say, if the outside dimension of emery wheel 16 is the biggest, the grinding angle for the grinding face of workpiece W is the least, and emery wheel sharpness is the lowest, can take large values when the outside dimension of emery wheel 16 is big, changes the time of grinding speed switching simultaneously, substantially makes fine grinding amount fix.By said method, even the emery wheel 16 that outside dimension is very big, sharpness is the lowest, the tapering of workpiece W inner surface also will not be made to become the biggest.
Afterwards, the workpiece of grinding some, the surface of emery wheel 16 is roughening, after machining accuracy step-down, make wheel face return by finishing shaping normal.And, can be gradually reduced by the outside dimension of finishing formed grinding wheel 16, along with outside dimension reduces, the grinding angle to workpiece W grinding face of emery wheel 16 can become greatly, sharpness can uprise.But, according to the outside dimension of emery wheel 16, corase grind incision feeding size B1 can realize multi-phase containment, also can realize electrodeless control.
Refining identical with during above-mentioned corase grind, incision supplying position changes according to the change of the outside dimension of emery wheel 16.
In sparking out, at the end of emery wheel 16 is for the incision feeding of workpiece W, the state before workpiece W and emery wheel 16 keep continues revolution.In this case, the sparking out time is the outside dimension according to emery wheel 16 and changes.When the outside dimension of emery wheel 16 is big, the least to the grinding angle of workpiece W, desired surface roughness can be obtained.When outside dimension diminishes, the sharpness of emery wheel 16 uprises, and surface roughness is deteriorated.
Owing to the incision supplying position of corase grind and fine grinding can change with grinding wheel radius change, cut residual volume at the end of roughly grinding and refine in the case of emery wheel 16 radius being big less.
But, even if according to aforesaid method for grinding, in the case of grinding wheel diameter is big, the cone angle at the end of ending grinding and sparking out is not improved.So, the method for grinding of the present embodiment makes the axle center changing corresponding gyroaxis 15 with grinding wheel diameter also change about the inclination angle of main shaft part 6 further.
Under conditions of grinding wheel diameter is big, the inclination angle of the main shaft part 6 that the axle center of gyroaxis 15 is corresponding, α is increased compared with inclination angle when of little with emery wheel 16 external diameter, as the change of the position of the feeding that the change at this inclination angle is cut with corase grind, radial dimension corresponding to emery wheel 16 is applicable not only to grading control, is also applied for electrodeless control.
Cutting speed according to original workpiece W, corresponding grinding wheel diameter can be not changed in certain limit, meanwhile can not only obtain desired surface roughness, the finishing size of internal diameter also can be made to determine within the specific limits, and the inclination in grinding face can be eliminated.
And then, according to the rotary position of adjustment main shaft part 6, if revising the grinding face of workpiece W, keep tilting, even if the most not changing after Xiu Zhenging according to the external surface shape self of emery wheel 16.That is the section of emery wheel 16 is along with greatly and repairing molding along the change slowly of front extreme direction.In this case the external diameter of emery wheel 16 is the biggest, and inclination during acquired finishing molding based on aforementioned grinding result will be the biggest, the when that outside dimension being little, tilts the thing reduced therewith and just need not speak more.
From above explanation, it can be clearly recognized that, if, with the inner face grinding attachment relevant to this utility model, adjust the angle of workpiece and the centre of gyration of emery wheel, emery wheel can be according to the inclination finishing molding of regulation, the amount of deflection of revolution when considering further that grinding, it is possible to obtain the suitable grinding face not having gradient.But reducing processing work piece inner surface when this grinding attachment is owing to making grinding by machinery and produce tapering, for this, we need to research and develop more high-quality and complete the device of grinding internal surface processing.
