Star gear, sun wheel assembly 22 form the sun gear of planetary gear mechanism.
As shown in Figure 3 and Figure 4, in loading and unloading, the piston rod of positioning cylinder 451 bounces back this kind of twin grinder, and it is fixed to make
Position pin 452 is detached from the dowel hole 4531 of positioning seat 453, and positioning component 45 is unable to locking rocker arm mechanism 4；The work of rocker arm cylinder 44
Stopper rod stretches out, and pushes the shaft 412 of tumbler assembly 41 to rotate by pivot joint ear 414 and locating rack 413, shaft 412 interlocks cantilever
42 swing, and upper millstone mechanism 1 is made to swing to 34 top of water receiving rack, and upper millstone mechanism 1 is not aligned with lower millstone mechanism 2 at this time, under
Above disc-grinding mechanism 2 there is biggish space to carry out operation of feeding and discharging for operator.
When operator carries out operation of feeding and discharging, the piston rod retraction of the external tooth cylinder 243 of external tooth coil assembly 24 makes activity
External tooth 242 declines, and the piston rod of subsequent sliding cylinder 64 stretches out, and makes under table top 633 and the lower millstone mechanism 2 of sliding table 63
Mill disk body 231 is drawn close, and table top 633 and lower mill layer 232 are in same level, and when blanking, staff can will be placed
The fixture 7 for having grinding to complete product is directly dragged in table top 633 from the lower mill layer 232 of lower millstone mechanism 2, can after the completion of blanking
To carry out feeding to next group product to be ground, when feeding, staff can will be placed with the fixture 7 of product to be ground from platform
It is directly dragged on the lower mill layer 232 of lower millstone mechanism 2 in face 633.
As depicted in figs. 1 and 2, after the completion of operation of feeding and discharging, the piston rod of sliding cylinder 64 bounces back, and makes sliding table 63
Table top 633 is separated with the lower millstone disk body 231 of lower millstone mechanism 2, and the piston rod of the external tooth cylinder 243 of external tooth coil assembly 24 is stretched
Out, increase movable external tooth 242, when movable external tooth 242 rises, the rotary table portion on the top of movable external tooth 242 is first connect with fixture 7
Touching, enables movable external tooth 242 smoothly to slip over the edge of fixture 7 and be unlikely to jack up fixture 7, after movable external tooth 242 rises,
Movable external tooth 242 and fixed external tooth 241 can be engaged with fixture 7.
When grinding work, the piston rod of rocker arm cylinder 44 bounces back this kind of twin grinder, passes through pivot joint ear 414 and positioning
Frame 413 pulls the shaft 412 of tumbler assembly 41 to rotate, and shaft 412 interlocks cantilever 42 and swings, and swings to down upper millstone mechanism 1
The top of disc-grinding mechanism 2, when upper millstone mechanism 1 will be aligned with lower millstone mechanism 2, the EDGE CONTACT of locating rack 413 to buffer
46 top, buffer 46 act and buffer the movement of rocker arm cylinder 44, and rocker arm body 4 is made to be unlikely to that hard collision occurs.On
When disc-grinding mechanism 1 and lower millstone mechanism 2 align accurate, the piston rod of positioning cylinder 451 stretches out, and is inserted into positioning pin 452 fixed
The dowel hole 4531 of position seat 453, thus locking rocker arm mechanism 4, and then lock the position of upper millstone mechanism 1；If upper millstone machine
Structure 1 and the contraposition of lower millstone mechanism 2 are inaccurate, even if the piston rod of positioning cylinder 451 stretches out, positioning pin 452 can not be inserted into fixed
The dowel hole 4531 of position seat 453, rocker arm body 4 cannot be locked；It can be with setting program, if the piston rod of rocker arm cylinder 44 is complete
The piston rod of full retraction and positioning cylinder 451 is fully extended, that is, represents positioning pin 452 and be inserted into dowel hole 4531, this
When upper millstone mechanism 1 and lower millstone mechanism 2 can star, start to grind, otherwise upper millstone mechanism 1 and lower millstone mechanism 2 be not
It can starting.
After upper millstone mechanism 1 starts, upper millstone cylinder 113 is acted, and declines upper millstone component 12, and altimeter 18 touches
After reference block 25, by information feedback to master control, the elevation information of upper millstone component 12 is reset and redefines current height by master control
Height on the basis of degree, upper millstone cylinder 113 continues to act, and upper millstone component 12 is made to continue to decline, and altimeter 18 is by upper millstone group
The displacement information of part 12 is fed back to master control, and master control is enable to know the upper mill layer 123 of upper millstone component 12 relative to reference block 25
Highly；When highly reaching preset height locating for altimeter 18 detects upper mill layer 123, master control control upper millstone cylinder 113 stops
Stop is made, and upper millstone component 12 stops pushing.
When being ground, sun turbin generator 261 starts this kind of twin grinder, and passes sequentially through sun gear speed reducer
262 and sun wheel shaft 263 be driven, rotate sun wheel body 222 and solar wheeling tooth 221,22 conduct of sun wheel assembly at this time
Driving wheel in planetary gear mechanism is rotated about their axes fixture 7.Lower millstone motor 211 starts, and passes sequentially through lower millstone and subtract
Fast machine 212 and lower millstone transmission shaft 213 are driven, and rotate lower millstone component 23；Upper millstone motor 111 starts, due to spherical hinge
Second driving cog 125 of 13 the first driving cog 131 and flange 122 is intermeshed, and upper millstone motor 111 can pass sequentially through mill
Disc decelerator 114, upper millstone transmission shaft 112 and spherical hinge 13 are driven, and rotate upper millstone component 12.Upper millstone component 12 it is upper
The lower mill layer 232 for grinding layer 123 and lower millstone component 23 is moved relative to the upper and lower surface of the product to be ground on fixture 7, thus
Rub the upper and lower surface of product to be ground, realizes the attrition process to product.
During the grinding process, spherical hinge 13 can not only be driven, and upper millstone component 12 can be made to be in quick condition, i.e., on
When the upper mill layer 123 of mill component 12 and the not parallel lower mill layer 232 of lower millstone component 23, the extrados and method of spherical hinge 13
The intrados of orchid 122 makes the angulation change of upper millstone component 12, so that the angle of the lower mill layer 232 of lower millstone component 23 is adapted to,
The upper mill layer 123 of upper millstone component 12 and lower mill layer 232 holding of lower millstone component 23 is set to be parallel to each other.
Above embodiment only indicates that rather than limits the utility model, therefore all according to the utility model patent application
The equivalent change or modification that method described in range is done, is included in the scope of the utility model patent application.
