Detailed description of the invention
For enabling above-mentioned purpose of the present invention, feature and advantage become apparent more, are described in detail the specific embodiment of the present invention below in conjunction with accompanying drawing.It should be noted that, accompanying drawing of the present invention all adopts the form of simplification and all uses non-ratio accurately, only in order to object that is convenient, the aid illustration embodiment of the present invention lucidly.
As shown in Figures 2 to 5, expansion controlling ring-shaped insert mill processing unit (plant) of the present invention, comprising: connector 200, eccentric disc 100, balance weight 300 and briquetting 400.Balance weight 300 and workpiece 500 are arranged on eccentric disc 100, and eccentric disc 100 is fixed on the main shaft benchmark of internal grinder by connector 200, and briquetting 400 is for pushing down described workpiece 500.
Please emphasis with reference to Fig. 4 and Fig. 5, described eccentric disc 100 comprises disc body 160, is positioned at first through hole 110 at described disc body 160 center, be positioned at this disc body 160 1 the second through hole 120 diametrically, and be evenly arranged in the some locating holes 130 on the annulus that is the center of circle of the second through hole 120 center.Preferably, this locating hole 130 is provided with 8, and the radius of described locating hole 130 place annulus equals the radius of datum hole (that is to say aperture) place annulus on workpiece 500, in other words, three meetings are had at least to overlap with datum hole on workpiece 500 in 8 locating holes 130 on eccentric disc 100, workpiece 500 can be accurately positioned on eccentric disc 100 in different angles by alignment pin 600, realize the fine finishining one by one of the macropore of 8 on workpiece 500.
Described disc body 160 is affixed with the main shaft benchmark of internal grinder by connector 200, and workpiece 500 is fixed on the center superposition of on the eccentric disc 100 and center of workpiece 500 and the second through hole 120, that is, workpiece 500 is eccentrically set on eccentric disc 100.Further, the diameter of described first through hole 110 is a bit larger tham the diameter with the macropore on described workpiece 500, and the distance of center circle between first, second through hole 110,120 equals the distance on workpiece 500 between the macropore center of circle to workpiece 500 center.That is, when workpiece 500 is fixed on eccentric disc 100,8 datum holes have at least 3 groups to overlap with between 8 locating holes 130, alignment pin 600 is utilized to be fixed on eccentric disc 100 by workpiece 500, now the first through hole 110 is completely corresponding with the position relationship between the position relationship between locating hole 130 and the large and small hole on expansion controlling ring-shaped insert, in other words, internal grinder only need carry out to of workpiece 500 macropore position degree that inner circle processing can guarantee this macropore, also can ensure the roughness of macropore simultaneously, make its roughness be less than 0.8.
As preferably, described balance weight 300 is arranged on the one end away from workpiece 500 on described eccentric disc 100, eccentric disc 100 is made to keep balance, described workpiece 500 presses solidly on described eccentric disc 100 by described briquetting 400, and the external diameter of described briquetting 400 is less than the diameter of the annulus at locating hole 130 place, namely described briquetting 400 does not affect described workpiece 500 and the location of eccentric disc 100, avoids workpiece 500 to add in rotation simultaneously and flies out man-hour.
As shown in Figure 7 and Figure 8, described briquetting 400 comprises briquetting body 410, be arranged on the installing hole 430 at described briquetting body 410 center, with the connecting hole 440 of installing hole 430 conllinear, and enclose the indent 420 offered Monday along the cylindrical of described briquetting body 410, the height of described indent 420 is identical with the height of workpiece 500, and the internal diameter of described indent 420 is identical with the internal diameter of described workpiece 500.Described briquetting body 410 edge is also provided with a breach 450, and the circular arc of the circular arc that this breach 450 is formed and described first through hole 110 matches, and for stepping down and protecting, has both avoided the processing affecting macropore, further ensure that again the position degree of macropore.
As preferably, described disc body 160 is also provided with the briquetting locating hole 140 corresponding with the connecting hole 440 on described briquetting body 410 and the bolt hole 150 corresponding with connector 200.
As shown in Figure 6, described connector 200 comprises first connecting portion 210 corresponding with described eccentric disc 100 and second connecting portion 220 affixed and corresponding with described internal grinder with the first connecting portion 210, first, second connecting portion 210,220 described is convex structure, the external diameter of first projection 211 at described first connecting portion 210 top is identical with the diameter of described first through hole 110, and described eccentric disc 100 is connected with the first platform 212 bolt bottom described first connecting portion 210; Second protruding 221 of described second connecting portion 220 top is connected with the first platform 212 integral type bottom described first connecting portion 210, and the second platform 222 bottom described second connecting portion 220 is bolted with the main shaft benchmark of internal grinder.Described connector 200 is for connecting main shaft benchmark and the eccentric disc 100 of internal grinder.
Continue with reference to Fig. 2 to Fig. 8, the process of expansion controlling ring-shaped insert mill processing unit (plant) of the present invention is:
First, workpiece 500 alignment pin 600 is positioned on eccentric disc 100, utilizes balance weight 300 to carry out the balance of adjustment eccentric disc 100 simultaneously.
Secondly, connector 200 is fixed on the main shaft benchmark of internal grinder, then the eccentric disc 100 mixing up balance is fixed on connector 200, with alignment pin 600, workpiece 500 is positioned on eccentric disc 100, with briquetting 400 workpiece pressing 500.
The grinding of a macropore is carried out in start, after mill processing dimension puts in place, unclamps briquetting 400, extracts alignment pin 600, rotational workpieces 500, then carries out the mill processing of second macropore, until after 8 hole complete wears, changes another workpiece 500.Because grinding out is last one manufacturing procedure of workpiece 500, shaping, so need not adjustment balance again.
Compared with prior art, because the same of expansion controlling ring-shaped insert is circumferentially uniformly distributed 8 macropores, and 8 apertures (datum hole) are circumferentially distributed in around macropore regularly at another, the present invention utilizes eccentric theoretical, devise eccentric disc 100, and arrange 8 locating holes 130, often processing a macropore all has alignment pin 600 to be fixed by workpiece 500, therefore ensure that the position degree in each macropore relative positioning hole 130, also ensure that the roughness of each macropore simultaneously.
Obviously, those skilled in the art can carry out various change and modification to invention and not depart from the spirit and scope of the present invention.Like this, if these amendments of the present invention and modification belong within the scope of the claims in the present invention and equivalent technologies thereof, then the present invention is also intended to comprise these change and modification.
