According to one embodiment of the application, the multi-thread emery wheel be combined the first dresser 3 of automatic trimming device with
Second dresser 4 is oppositely arranged, i.e., the diamond roller 35 of the first dresser 3 is set towards left, and the second emery wheel is repaiied
The diamond roller 45 of whole device 4 is set towards right.
According to one embodiment of the application, the grinding servomotor 56 that the multi-thread emery wheel is combined automatic trimming device is set
In the top of fuselage 1.
According to one embodiment of the application, the multi-thread emery wheel is combined the mill ditch emery wheel 52 and sharpening sand of automatic trimming device
The centre-to-centre spacing of wheel 51 is 25mm.
The operation principle of the present invention is that the first dresser 3 is driven by finishing motor 33, and trimmed power transmission shaft 31 is realized
The rotary motion of diamond roller 35, trimmed drive disk assembly 32 realizes diamond roller under the driving of finishing servomotor 34
35 along the radial and axial both direction of abrasive grinding wheel feed motion, the second dresser 4 works with the first dresser 3
Principle is identical.The driving grinding power transmission shaft 55 of grinding motor 53 realizes the rotation of abrasive grinding wheel, and grinding servomotor 56 is passed through grinding
Dynamic component 54 realizes the feeding of abrasive grinding wheel along the vertical direction.During crushing, the linear speed of abrasive grinding wheel and finishing emery wheel
Degree must keep certain ratio, take 0.4 ~ 0.7.
As shown in Figure 2,3, the finishing number of times of the first dresser 3 and the second dresser 4 is adjustable, can be single branch mill
Crushing or the finishing of branched abrasive grinding wheel are cut, the first dresser 3 is above abrasive grinding wheel from right to left first to mill
Sharp sand wheel 51 is repaired, then mill ditch emery wheel 52 is repaired, and the dressing process of the second dresser 4 is in contrast.First
The crushing process of dresser 3 is divided into the F.F. of sharpening emery wheel, sharpening emery wheel work and enters, grinds the F.F. of ditch emery wheel, mill ditch emery wheel work
Enter and five stages of rewind.Sharpening emery wheel fast forward stage, diamond roller 35 is along straight line fast feed；Sharpening emery wheel work is advanced
Section, diamond roller 35 is fed along the mill outer contour of spiral shell sharp sand wheel 51 with work speed；Grind ditch emery wheel fast forward stage, diamond rolling
Wheel 35 proceeds to the initial profile line position of mill ditch emery wheel 52 soon；Mill ditch emery wheel work enter the stage, diamond roller 35 along mill spiral shell ditch emery wheel
52 contour lines are fed with work speed；Rewind stage, mill ditch emery wheel 52 and sharpening emery wheel 51 retract downwards to emery wheel zero point, Buddha's warrior attendant
Stone roller 35 is quickly returning to initially repair zero-bit, and is ground next time in this, as basic data.
Two dressers use the initial dressing method along abrasive grinding wheel radial feed, the sharpening sand in grinding process
Wheel 51 is different with the wear extent of mill ditch emery wheel 52, therefore the compensated distance amount of abrasive grinding wheel is ground with two panels emery wheel during crushing
The big value of damage amount is defined.The finishing amount compensation process of two dressers is fixed value compensation method, in crushing program
Compensation rate is adjustable；In dressing process, zero point original position of the emery wheel in lathe coordinate system is changeless, for different size
Screw tap, the initial position of sharpening emery wheel 51, mill ditch emery wheel 52 and diamond roller 35 is different, and emery wheel external diameter minimum point is protected all the time
Hold the distance with screw tap external diameter 2mm.
Embodiment described above only represents the several embodiments of the present invention, and it describes more specific and detailed, but not
It is understood that as limitation of the scope of the invention.It should be pointed out that for the person of ordinary skill of the art, not departing from
On the premise of present inventive concept, various modifications and improvements can be made, these belong to the scope of the present invention.Therefore this hair
Bright protection domain should be defined by the claim.
