The specific embodiment
below in conjunction with accompanying drawing and preferred embodiment of the present invention, technical scheme of the present invention is further elaborated.
cutter sweep shown in Figure 3, is mainly used in hard brittle material to carry out cutting processing.This cutter sweep comprises support 1, Mobile base 2, lift drive mechanism (not shown), and support 1 fixes with cutting equipment integral body, and Mobile base 2 vertically can be arranged on support 1 up and down by lift drive mechanism.By rotary drive mechanism (not shown), can around Pivot Point Center line, be arranged on rotatably the bottom of Mobile base 2 for to be cut 3, in the present embodiment, what adopt for to be cut 3 is sapphire bar.
shown in Figure 4, to be cut 3 is to be arranged in the following manner on Mobile base 2: an end face of to be cut 3 is bonded with flitch 8 regularly, is bonded with regularly spherical pad 10 on its other end.The bottom of Mobile base 2 is provided with rotatable rotating shaft 7, rotary drive mechanism is for driving the rotation of rotating shaft 7, the bottom of Mobile base 2 is also provided with ball-type thimble 11, ball-type thimble 11 can move vertically, ball-type thimble 11 distributes along same rectilinear direction with the axial line of rotating shaft 7, rotating shaft 7 is fixed with a magnechuck 9 on the end of ball-type thimble 11, during this magnechuck 9 energising, flitch 8 can be pull-in on magnechuck 9 regularly, and the thimble portion of ball-type thimble 11 conflicts on spherical pad 10 vertically.Install to be cut 3 o'clock, first flitch 8 and spherical pad are bonded on the end face at its two ends, then make magnechuck 9 energisings make magnechuck 9 and flitch 8 adhesives, and then the position of adjustment ball-type thimble 11, its thimble portion is conflicted on spherical pad 11, so just, treat cutting member 3 and locate, during rotating shaft 7 rotation, to be cut 3 rotates thereupon.Above-mentioned employing ball-type thimble 11 fixes to be cut 3, in fixing process, can, according to factors such as self size of to be cut 3 and precision and cutting angles, its radial angle self adaptation be adjusted, and without manually adjusting, install more convenient again.In above-mentioned installation, magnechuck 9 is also replaceable for for clamping the fixture of flitch 8, and by the fixing one end of flitch 8 of fixture, but the fixed form of employing magnechuck 9 is more convenient.
shown in Figure 3, this cutter sweep also comprises the cutting mechanism being arranged on support 1, this cutting mechanism comprises steel wire 12 for cutting, three multi-thread sheaves 4 that form many cutting wires for winding steel wire 12, 5, 6, in the present embodiment, what steel wire 12 adopted is golden steel wire, three multi-thread sheaves are down " product " font and arrange, in the perimembranous of each multi-thread sheave, all offer a plurality of wire casings that distribute along self axially spaced-apart, a wire casing of the first multi-thread sheave 6 by below of steel wire 12 tangentially enters a wire casing of multi-thread sheave 4 successively after drawing, enter a wire casing of multi-thread sheave 5, and then tangentially enter the next wire casing of multi-thread sheave 6, so circulation and tensioning ground winding forms many cutting wires in the perimembranous of three multi-thread sheaves, these many cutting wires distribute along the axially spaced-apart of multi-thread sheave, a plurality of cutting positions on corresponding to be cut 3 are distinguished in the position of these many cutting wires.The two ends of steel wire 12, by the Winder folding and unfolding on cutting equipment, make cutting wire move back and forth the cutting driving mechanism (not shown) of cutting thereby be also provided with on support 1 for driving multi-thread sheave 6 to rotate.By cutting driving mechanism, drive 6 rotations of multi-thread sheave, many cutting wires move back and forth thereupon, when Mobile base 2, vertically fall while touching cutting wire rotatably to be cut 3, and cutting wire cuts along the cutting member 3 of radially treating of to be cut 3.
shown in Fig. 3, Fig. 5, this cutter sweep is when treating cutting member 3 and cut, under the effect of rotary drive mechanism, rotate for to be cut 3, under the effect of lift drive mechanism, vertically decline simultaneously, under the effect of cutting driving mechanism, steel wire 12 moves back and forth, and many cutting wires of steel wire 12 contact gradually the bottom of to be cut 3 and little by little cut the core of to be cut 3.To be cut 3 very short with the contact wire of cutting wire, this is more easy for the large diameter superhard super crisp material of cutting, during cutting, the energy consumption of cutting equipment reduces greatly, its power also can significantly reduce, the continuous and effective that has guaranteed cutting is carried out, and is applicable to the cutting processing of multiple large scale hard brittle material.
certainly, while adopting the cutting method of above-mentioned incision principle to cut to be cut 3 of hard brittle material, also to be cut 3 vertically can be arranged or arrange along other angles, in cutting process, only need to guarantee that to be cut 3 is being rotated along the direction perpendicular to be cut 3 rotation centerlines and move towards many cutting wire feedings, make cutting wire along to be cut 3 radially it is cut.
above-described embodiment is only explanation technical conceive of the present invention and feature, and its object is to allow person skilled in the art can understand content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences that Spirit Essence is done according to the present invention change or modify, within all should being encompassed in protection scope of the present invention.
