The specific embodiment:
Below in conjunction with accompanying drawing narration embodiment, the present invention is further specified, because statement is non exhaustive, the similar implementation method of the present invention does not constitute restriction to the present invention;
Like Fig. 1, Fig. 2, shown in Figure 3, during installation, need the present invention's two covering devices to be used at least.Two these devices of cover are installed in the horizontal plane of lathe bed 1; On godet 4 teeth groove of two covering devices, come winding, make it form gauze, godet 4 rotation under main shaft stiff end 3 direct-connected synchronous motors 2 act on around Metal Cutting line 7; Drive godet 4 and 8 rotations of main shaft movable end through trundle; Thereby drive Metal Cutting line 7 high-speed motions, when workpiece 5 behind the cutting gauze that slowly moves downward under the guiding of planker 6 through high-speed motion, will be cut into silicon chip by the Metal Cutting line 7 of a rule.The line footpath of the slot pitch of teeth groove or Metal Cutting line 7 on the adjustment godet 4, the silicon wafer thickness that finally just can obtain wanting.
As shown in Figure 4; The electric machine main shaft sleeve 13 of main shaft stiff end of the present invention is fixing with lathe bed 1 through flange seat 9; Motor stator 14 is loaded in the endoporus of electric machine main shaft sleeve 13, and rotor 15 is connected through interference fit and electric machine main shaft 16, and electric machine main shaft 16 supports through motor left bearing 28 and motor right bearing 30; It is top 22 to assemble removable stiff end in the 20 front end interference of stiff end tail spindle, and the rear end links to each other with electric machine main shaft 16 through coupking shaft 17.When lathe was given motor stator 14 power supplies through cable 12, rotor 15 rotate under the magnetic field force effect, rotated thereby drive electric machine main shaft 16, and passed through that coupking shaft 17 drive stiff end tail spindles 20, stiff end are top 22, stiff end trundle 23 rotates synchronously.Stiff end tail spindle 20 front ends have one can only bear the stiff end cylinder roller bearing 21 of big load; With the tractive force that bears godet 4, Metal Cutting line 7 and the load of axis system; The rear end is a pair of high accuracy angular contact ball bearing 18, to bear the axial force of axis system.In order to solve the heating problem of main shaft in rotation process, motor head water inlet pipe 24 and 25 pairs of electric machine main shafts of motor head return pipe 16 and stiff end tail spindle 20 through motor swivel joint 26 cool off; Cool off through motor water inlet pipe 27 and 29 pairs of motor housings of motor return pipe; Cool off through stiff end water inlet pipe 10 and stiff end return pipe 11 diagonal angle contact ball bearings 18, stiff end cylinder roller bearing 21 and bearing sleeve 19.
As shown in Figure 5, the rotation of main shaft movable end is the rotation that relies on main shaft stiff end synchronous motor 2, through stiff end trundle 23, and godet 4, movable end trundle 33 and rotate.Rolling center 32 is contained on the movable end tail spindle 36 through interference fit; Movable end tail spindle 36 front ends have one can only bear the movable end cylinder roller bearing 34 of big load; With the tractive force that bears godet 4, Metal Cutting line 7 and the load of axis system; The rear end is a pair of high accuracy movable end angular contact ball bearing 37, to bear the axial force of axis system.Bearing sleeve 35 is the same with the structure of main shaft stiff end; But be not be directly installed on the lathe bed 1 fixed; But can in movable end fixed cover 38, endwisely slip; Thereby the parts in the bearing sleeve 35 comprise that rolling center 32 all is axially movable, to get out of the way the loading position of godet 4.This part moves forward and backward through spanner rotating screw bolt 39 and realizes.In order to solve the heating problem of main shaft in rotation process, cool off through movable end water inlet pipe 41 and 42 pairs of movable end cylinder roller bearings 34 of movable end return pipe, movable end angular contact ball bearing 37 and bearing sleeve 35; Right side water inlet pipe 43 through movable end swivel joint 44 cools off with 45 pairs of movable end tail spindles 36 of right side return pipe.
Like Fig. 6, shown in Figure 7, godet 4 is made up of inner conical drogue 46,49, godet sleeve 47, polyurethane glue-line 48.Adhere to one deck polyurethane glue-line 48 on the godet sleeve 47, have on polyurethane glue-line 48 cylindricals that hundreds of～several thousand strips are identical, profile of tooth is a triangle, the ring slot of certain depth is arranged, Metal Cutting line 7 is back and forth around wherein.Godet sleeve 47 two ends endoporus have stiff end inner conical drogue 46, movable end inner conical drogue 49, and during use, the rolling center 32 with stiff end of main shaft stiff end top 22 and main shaft movable end assembles respectively; 4 circular holes are respectively arranged on godet sleeve 47 both ends of the surface, during use, respectively with movable end trundle 33 assemblings of stiff end trundle of main shaft stiff end 23 and main shaft movable end after; With long draw 31 with main shaft stiff end, godet and main shaft movable end in axial tension; With nut 40 lockings, make main shaft stiff end 3, godet 4 again; Main shaft movable end 8 three parts connect as a whole, guarantee the synchronous rotation of whole axis system.
Like Fig. 7, shown in Figure 8, the present invention proposes two kinds of top tip structure forms, i.e. top 22, the rolling center 32 of stiff end, and stiff end inner conical drogue 46, movable end inner conical drogue 49 both can adopt taper seat top tip structure form, and 15 °～25 ° of cone angle scopes are generally got 20 °.Also can adopt sphere top tip structure form, spherical radius SR scope SR40～SR85 generally gets different spherical radius according to the outside diameter size of godet 4.The top manufacturing cost of taper seat is lower, but requires high to the axiality of main shaft stiff end and main shaft movable end; The top axiality to main shaft stiff end and main shaft movable end of sphere requires low, but manufacturing cost can be selected than higher in use as the case may be.
