Fig. 2 is the sectional view of grinding head device of the present invention.
Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, the present invention is described in further detail.
As depicted in figs. 1 and 2, the invention provides a kind of grinding head device, comprise bistrique revolution system 1 and abrading block seat oscillation system 2, bistrique revolution system 1 and abrading block seat oscillation system 2 adopt different drive sources.
Wherein, bistrique revolution system 1 comprises grinding spindle 11, bistrique adpting flange 12, grinding spindle adapter sleeve 13 and bistrique lower box 14, bistrique adpting flange 12 is arranged on grinding spindle 11, bistrique adpting flange 12 is connected with the first driving mechanism, for giving described grinding spindle 11 by power transmission, grinding spindle 11 is connected with bistrique lower box 14 by grinding spindle adapter sleeve 13, grinding spindle 11 drives bistrique lower box 14 to rotate by grinding spindle adapter sleeve 13 and inner components rotates, and realizes the high speed revolution of bistrique.
Revolving round the sun with existing bistrique adopts gear to carry out compared with the structure of three grades of transmissions, and all gear drives of bistrique are all removed by the present invention, simplify structure.Do not re-use gear drive in bistrique, bistrique revolution directly adopts the form of direct spindle drive, and structure is simple, smaller volume, weight saving, and failure rate is low, maintenance are easily.And grinding spindle drives bistrique lower box to rotate and inner components rotates, realize the high speed revolution of bistrique, turn scooter 1000 revs/min, but the highest revolution of bistrique only has 520 revs/min at present.
Described abrading block seat oscillation system 2 comprises driving mechanism 21 and the abrading block seat swing mechanism 22 of the swing of abrading block seat, the driving mechanism 21 that described abrading block seat swings comprises driven pulley 210, driven pulley fixed cover 211, waveform cam 212, cingulum 213 and waveform cam connection bearing 214, driven pulley fixed cover 211 is connected with waveform cam 212, driven pulley 210, driven pulley 210 is provided with cingulum 213, described driven pulley 210 is connected with the second driving mechanism by described cingulum 213, for giving described waveform cam 212 by power transmission.
Described cingulum 213 by power transmission to driven pulley 210, driven pulley 210 transmits power to waveform cam 212 by driven pulley fixed cover 211, realize the drive of waveform cam 212, this motion and grinding spindle 11 drive the revolution of bistrique without any associate.Further, above-mentioned drives structure is very simple, and driving principle is also very simple, and installation and maintenance are easy.
The waveform cam 212 of described abrading block seat oscillation system 2 is set in by waveform cam connection bearing 214 on the grinding spindle adapter sleeve 13 of bistrique revolution system 1, namely waveform cam 212 is by waveform cam connection bearing 214 together with grinding spindle adapter sleeve 13 empty set, and it is separate for ensureing that bistrique revolution and waveform cam 212 rotate.Therefore, being separate between bistrique revolution system 1 of the present invention and abrading block seat oscillation system 2, there is not the relation of interrelated, mutual restriction in the two, and the revolution speed of bistrique clog-freely in the least can carry out high rotating speed, rotating speed can bring up to more than 1000 rev/min, thus improves grinding efficiency.On the other hand, in order to ensure polishing grinding quality, the swing speed of abrading block seat requires very low, requires low speed oscillations.Because the present invention is independent control, waveform cam independently can realize low speed rotation, produces a speed discrepancy with the revolution of bistrique, and this speed discrepancy will determine the speed of the swing of abrading block seat.Because this speed discrepancy is free to adjustment, therefore the speed of the swing of abrading block is also be free to adjustment, and the present invention utilizes bistrique revolution and abrading block seat driven at low speed at a high speed, realizes low frequency abrading block and swings, and reduces bistrique vibration.
Concrete, be linked together by bearing between driven pulley 210 and grinding spindle adapter sleeve 13.
Described driven pulley 210 is provided with driven pulley end cover 217, and driven pulley end cover 217 is fixed on driven pulley 210 by end cover hold-down screw 218, can extend the service life of driven pulley 210.Be connected by bearing between driven pulley end cover 217 with grinding spindle 11.
