Swing, finally, axial wobble of the abrading block 2221 around actively fork 2223.
It is all the time line contact with ceramic tile that the swing of abrading block seat 2222 makes abrading block 2221.The grinding motion of bistrique is abrading block
2221 around grinding spindle 211 circumference rotary motion and abrading block 2221 around actively fork 2223 left rotation and right rotation swing two kinds motion
The compound motion of composition, makes the linear contact of abrading block 2221 and institute flat surface grinding, therefore is ground pressure greatly, and abrading block swings, mill
Pure abrasive particle can squeeze during quickly here swings it is broken go out new processing corner angle, while it is machined go out sand also can with grind pure abrasive particle
Easily discharge in side-to-side movement together, and the gap of abrading block will not be blocked.
Present invention firstly provides high speed polishing grinding head device, is divided into upper and lower two parts.Upper part drive system, is separated
For the drive form of primary and secondary two, for driving bistrique revolution and abrading block seat wobble drive respectively.Lower part bistrique, is also divided simultaneously
Swing no longer interrelated from for two parts, the revolution of bistrique and abrading block seat, but it is separate.And, the structure of bistrique
It is simplified, using the direct drive form of grinding spindle, hinders the obstacle that rotating speed is improved to be removed, and devises belt drives mill
Block swings.Therefore the present invention installs easy, easy to maintenance, the volume of bistrique diminishes, weight saving, and cost is reduced, and vibration reduces.
High speed polishing grinding head device of the present invention, bistrique revolution and abrading block seat swing the form for belonging to separate driving.Mill
The revolution speed of head can be improved with unimpeded carrying out, and rotating speed can bring up to more than 1000 revs/min.The swing speed of abrading block seat
Require very low, it is desirable to low speed oscillations.Because the present invention is independent driving, this swing speed can be easily controlled.Cam
Rotating speed driven by secondary drive system, rotating speed is low, and the vibration of cam is little, wear and tear it is little.The high rotating speed of bistrique revolution is low with cam
Speed discrepancy is realized between rotating speed, this speed discrepancy will determine the speed that abrading block seat swings.And passing through the present invention can arbitrarily adjust
Whole swing speed.
The principle being embodied as is as follows：
Here is assembled together driving means and grinding head device to illustrate, as shown in Figure 7.
（1）Bistrique high speed revolution implementation principle：
Main drive motor 110 by main driving driving pulley 112, V-belt 115 drive main driving driven pulley 113, from
Movable belt pulley main shaft 114 rotates, and driven pulley main shaft 114 is coupled together with main drive shaft 111, and driven pulley main shaft 114 will
Rotary power is transferred to main drive shaft 111, and the end of main drive shaft 111 couples main drive shaft adpting flange 116, real
The quick revolution of existing bistrique.
Grinding spindle 211 is linked together by bistrique adpting flange 212 with main drive shaft adpting flange 116.Main drive
The high-speed rotation of dynamic main shaft 111 passes to grinding spindle by main drive shaft adpting flange 116, bistrique adpting flange 212
211.Grinding spindle 211 drives whole bistrique lower box 214 and inner components rotation by grinding spindle adapter sleeve 213,
Realize the high speed revolution of bistrique.Rotating speed can reach more than 1000 revs/min, improve bistrique efficiency.The highest of current bistrique is public
Turn only 520 revs/min.
（2）Abrading block seat oscillation system slowly runs implementation principle：
Rotary power is passed to time drive shaft adapter sleeve by the secondary motor 130 of low speed by time drive shaft 131
132, secondary drive shaft adapter sleeve 132 passes to sliding axle 133 again, is ultimately transferred to master tape wheel drive shaft 134, master tape wheel drive
Axle 134 drives the driving pulley 135 being fixed thereon to rotate.Then, the low speed rotation of driving pulley 135 is passed by cingulum 2213
Pass driven pulley 2210.The tightness of cingulum 2213 is freely adjusted by tensioning wheel 142, and driven pulley 2210 is by driven
Belt wheel fixed cover 2211 passes to waveform cam 2212, the low speed rotation of drive waveforms cam 2212.The rotation of waveform cam 2212 is driven
Dynamic actively fork 2223 swings, and abrading block seat 2222 is connected in actively fork 2223, and actively fork 2223 drives abrading block seat 2222
Swing, abrading block 2221 is arranged on abrading block seat 2222.Finally, axis oscillating of the abrading block 2221 around actively fork 2223.Waveform
Cam 2212 can be independent realize low speed rotation, produce a speed discrepancy with the revolution of bistrique, this speed discrepancy can be free
Adjustment, the hunting frequency of abrading block be also be free to adjustment.
（3）Bistrique is moved up and down
Cylinder 150 is moved by air pressure pusher cylinder axle 151, and cylinder axis 151 drive fixed plate 122 to move.Slip cap 120
It is fixed in fixed plate 122, therefore, fixed plate 122 drives slip cap 120 to move up and down along connecting bushing 126 again.Balance plate
127 are fixed on slip cap 120, and slip cap 120 drives balance plate 127 to move up and down again.The lower end connection of main drive shaft 111
Main drive shaft adpting flange 116, main drive shaft 111 drives main drive shaft adpting flange 116 to move up and down.It is main to drive master
Axle adpting flange 116 connects bistrique, drives bistrique to move up and down.
Master tape wheel drive shaft 134 is fixed on balance plate 127 by balance set 141, and tension wheel shaft 143 passes through tension wheel shaft
On the stable equilibrium plate 127 of fixing nut 144.Therefore while slip cap 120 is moved up and down, master tape wheel drive shaft 134, tensioning wheel
Axle 143, tensioning wheel 142, driving pulley 135 are also synchronous to be moved up and down, and is synchronously moved up and down with bistrique, realizes primary and secondary driving
The synchronizing moving of system.
The above is the preferred embodiment of the present invention, it is noted that for those skilled in the art
For, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications are also considered as
Protection scope of the present invention.
