Detailed description of the invention
For making the object of the application, technical scheme and advantage clearly, below in conjunction with drawings and the specific embodiments, the application is described in further detail.
In the following description, quoting of " embodiment ", " embodiment ", " example ", " example " etc. is shown that the embodiment of so description or example can comprise special characteristic, structure, characteristic, character, element or limit, but not each embodiment or example must comprise special characteristic, structure, characteristic, character, element or limit.In addition, reuse phrase " embodiment according to the application " although be likely refer to identical embodiment, and not necessarily refers to identical embodiment.
For the sake of simplicity, eliminate in below describing and well known to a person skilled in the art some technical characteristic.
According to an embodiment of the application, a kind of multi-thread emery wheel compound automatic trimming device is provided, as shown in Figure 1 to Figure 3, comprise fuselage 1, be provided with grinding workbench 6 below fuselage 1, also comprise be connected with fuselage 1 top by supporting lever 2 the first dresser 3, be arranged at the second dresser 4 on grinding workbench 6 and be arranged at the grinding mechanism 5 between the first dresser 3 and the second dresser 4; First dresser 3 is identical with the structure of the second dresser 4, include diamond roller 35,45, finishing motor 33,43, finishing servomotor 34,44, finishing power transmission shaft 31,41 and finishing drive disk assembly 32,42, finishing motor 33,43 is connected with diamond roller 35,45 by finishing power transmission shaft 31,41, and finishing servomotor 34,44 is connected with diamond roller 35,45 by finishing drive disk assembly 32,42; Grinding mechanism 5 comprises abrasive grinding wheel, grinding motor 53, grinding servomotor 56 and the grinding power transmission shaft 55 be arranged in fuselage 1 and grinding drive disk assembly 54, grinding motor 53 is connected with abrasive grinding wheel by grinding power transmission shaft 55, grinding servomotor 56 is connected with abrasive grinding wheel by grinding drive disk assembly 54, abrasive grinding wheel is made up of the mill ditch emery wheel 52 coaxially arranged and sharpening emery wheel 51, mill ditch emery wheel 52 is for the groove grinding of spiral pointed tap, and sharpening emery wheel 51 is for the spiral shell point grinding of spiral pointed tap; Be provided with control assembly 7 in fuselage 1, control assembly 7 and finishing motor 33,43, repair servomotor 34,44, grinding motor 53 and grinding servomotor 56 be electrically connected.
According to an embodiment of the application, first dresser 3 of this multi-thread emery wheel compound automatic trimming device and the second dresser 4 are oppositely arranged, namely the diamond roller 35 of the first dresser 3 is towards left setting, and the diamond roller 45 of the second dresser 4 is towards right setting.
According to an embodiment of the application, the grinding servomotor 56 of this multi-thread emery wheel compound automatic trimming device is arranged at above fuselage 1.
According to an embodiment of the application, the mill ditch emery wheel 52 of this multi-thread emery wheel compound automatic trimming device and the centre-to-centre spacing of sharpening emery wheel 51 are 25mm.
Operation principle of the present invention is, first dresser 3 is driven by finishing motor 33, the rotary motion of diamond roller 35 is realized through finishing power transmission shaft 31, under the driving of finishing servomotor 34, realize the feed motion of diamond roller 35 along the radial and axial both direction of abrasive grinding wheel through finishing drive disk assembly 32, the second dresser 4 is identical with the first dresser 3 operation principle.Grinding motor 53 drives grinding power transmission shaft 55 to realize the rotation of abrasive grinding wheel, and grinding servomotor 56 realizes abrasive grinding wheel feeding along the vertical direction through grinding drive disk assembly 54.In crushing process, the linear velocity of abrasive grinding wheel and trimming wheel must keep certain ratio, gets 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 abrasive grinding wheel finishing and also can be the finishing of branched abrasive grinding wheel, first dresser 3 is first repaired sharpening emery wheel 51 from right to left above abrasive grinding wheel, repair mill ditch emery wheel 52, the second dresser 4 dressing process in contrast again.First dresser 3 crushing process is divided into the F.F. of sharpening emery wheel, sharpening emery wheel work is entered, grind the F.F. of ditch emery wheel, grind ditch emery wheel work enters and rewind double teacher.Sharpening emery wheel fast forward stage, diamond roller 35 linearly fast feed; Advanced section of sharpening emery wheel work, diamond roller 35 takes turns 51 outer contours with work speed feeding along mill spiral shell sharp sand; Mill ditch emery wheel fast forward stage, diamond roller 35 proceeds to mill ditch emery wheel 52 initial profile line position soon; Advanced section of mill ditch emery wheel work, diamond roller 35 is along grinding spiral shell ditch emery wheel 52 outline line with work speed feeding; In the rewind stage, rollback is to emery wheel zero point downwards for mill ditch emery wheel 52 and sharpening emery wheel 51, and diamond roller 35 is got back to fast and initially repaired zero-bit, and carries out grinding next time in this, as basic data.
Two dressers adopt the initial method for trimming along abrasive grinding wheel radial feed, in grinding process, sharpening emery wheel 51 is different with the wear extent of mill ditch emery wheel 52, therefore in crushing process, the compensated distance amount of abrasive grinding wheel is as the criterion with the value that two panels abrasion of grinding wheel amount is large.The trim amount compensation method of two dressers is fixed value compensation method, and in crushing program, compensation rate is adjustable; In dressing process, the zero point original position of emery wheel in lathe coordinate system is changeless, for the screw tap of different size, the initial position of sharpening emery wheel 51, mill ditch emery wheel 52 and diamond roller 35 is all different, and emery wheel external diameter minimum point remains the distance with screw tap external diameter 2mm.
The above embodiment only represents several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not be interpreted as limitation of the scope of the invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to scope.Therefore protection scope of the present invention should be as the criterion with described claim.
