Description
Technical field
The present invention relates to mechanical field, is a kind of vertical face grinding machine main shaft wheel dresser specifically.
Background technology
Face grinding machine is generally used in Precision Machining, is that the end face by emery wheel carries out Precision Machining to the plane of workpiece, because the required precision of processing work is high, so the quality of abrasive wheel end face quality, directly has influence on the machining accuracy of workpiece.
The finishing mode of face grinding machine emery wheel mainly be take manual trim as main at present.In dressing process, be to lean on manually completing of operator, when having increased operator's labour intensity, also higher to operator's technical ability requirement, otherwise the end face of emery wheel is easy to be accomplished middle protruding or umbilicate shape, affects the machining accuracy of lathe; The trim amount of emery wheel and the bad control of finishing time; The abrasive wheel end face shape of every twice finishing has difference, and machine tool accuracy changes greatly.
Summary of the invention
For solving the problems of the technologies described above, the object of this invention is to provide a kind of accurate face grinding machine automatic trimming device, be arranged on face grinding machine, the precise dressing of realization to end face grinding abrasive disk end face, make the end face of emery wheel there is higher flatness, meet the processing request of precision workpiece, be mainly used on vertical single, double face grinding machine.Concrete technical scheme is as follows:
A kind of accurate face grinding machine automatic trimming device, trimmer main shaft is positioned by pair of horns contact ball bearing, be fixed in trimmer seat hole, the upper end of trimmer main shaft arranges driven synchronous pulley, driven synchronous pulley connects active synchronization belt wheel by synchronous belt, active synchronization belt wheel is connected with decelerator, and described decelerator is connected with servomotor; The lower end of trimmer main shaft arranges automatic dressing dish; Described automatic dressing dish is semicircle, is fixed with polylith rectangle finishing piece on circumference 180 degree; Automatic dressing dish is rotated centered by trimmer main shaft, with rectangle finishing piece, emery wheel is repaired.
On the cylindrical of described trimmer main shaft upper end, little sensing chip is set, on described trimmer seat, approach switch is set; Approach switch can sense little sensing chip and pass the signal along to the control centre of grinding machine, and Bing You control centre is according to the rotational angle of the signal judgement automatic dressing dish sensing, in order to avoid and Wheel Interference.
The quantity of described rectangle finishing piece is 8.
On described automatic rest and reorganization dish, a plurality of grooves are set, in the centre of each groove, fixed block are set, described fixed block is fixed by bolts on automatic dressing dish, between fixed block and described groove, finishing piece is set.
Advantage of the present invention is: because automatic dressing dish is for semicircle, little sensing chip is set on the cylindrical of trimmer main shaft upper end, approach switch is set on described trimmer seat, by determining the angle of automatic dressing dish, avoid automatic dressing dish and Wheel Interference; Adopt rectangle finishing piece can be convenient to processing finishing piece; The fixed form conveniently replaced finishing piece of finishing piece on automatic dressing dish.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the top view of Fig. 1;
Fig. 3 is the fixed structure schematic diagram of finishing piece on automatic dressing dish;
In figure, 1, approach switch, 2, little sensing chip, 3, rectangle finishing piece, 4, automatic dressing dish, 5, driven synchronous pulley, 6, screw, 7, end face grinding abrasive disk, 8, trimmer main shaft, 9, trimmer seat, 10, Timing Belt, 12, motor cabinet, 13, adjust screw, 15, decelerator, 16, servomotor, 17, active synchronization belt wheel, 18, groove, 19, fixed block, 20, bolt.
The specific embodiment:
As shown in Figure 1-Figure 3, trimmer main shaft 8 is by the positioning support of angular contact ball bearing, be fixed in trimmer seat 9 holes, trimmer main shaft 8 upper surfaces connect driven synchronous pulley 5, little sensing chip 2 is connected on trimmer main shaft 8 upper end cylindricals, make little sensing chip 2 and the gap that is fixed on the approach switch 1 on trimmer seat 9 be transferred to 2mm left and right, allow approach switch 1 can sense little sensing chip 2, trimmer main shaft 8 lower surfaces connect automatic dressing dish 4, while connecting automatic dressing dish 4, to note, to when aliging with approach switch 1, install little sensing chip 2, make disk body and the end face grinding abrasive disk 7 of automatic dressing dish 4 on grinding wheel spindle moving direction, not produce interference, again trimmer seat 9 is connected in the other lathe bed of grinding wheel spindle, with screw 6, fix.Servomotor 16 is connected with decelerator 15, and is first connected on motor cabinet 12 with screw 6, need not tighten, and active synchronization belt wheel 17 is connected on the output shaft of decelerator 15, then by motor cabinet 12 be connected to bed piece after, with screw 6, fix; Then, by Timing Belt 10, active synchronization belt wheel 17 and driven synchronous pulley 5 are coupled together, with adjusting screw 13, the degree of tightness of Timing Belt 10 is regulated again, screw 6 is tightened, Timing Belt 10 can be passed on the rotary power of servomotor 16 outputs to driven synchronous pulley 5 by active synchronization belt wheel 17, then pass on to automatic dressing dish 4 by trimmer main shaft 8.Finally, 8 rectangle finishing pieces 3 are installed on automatic dressing dish 4, set grinding wheel spindle pick feed time, the amount of feeding, finishing number of times, automatic dressing dish rotating speed, grinding wheel spindle rotating speed etc., just can repair emery wheel.
During use, trimmer seat and motor cabinet need be fixed on end face grinding machine tool, be screwed, and tightness of synchronous belt is adjusted.
When to crushing, by setting the rotating speed of servomotor, automatic dressing dish is rotated according to suitable rotating speed, grinding wheel spindle is rotating to the timing of automatic dressing dish, is quantitatively moving, automatic dressing dish often rotates a circle, rectangle finishing piece is once repaired emery wheel, set grinding wheel spindle pick feed time, the amount of feeding, finishing number of times, automatic dressing dish rotating speed etc., realize timing finishing, quantitatively finishing, uniformity finishing, the high-quality finishing of emery wheel, be convenient to the quantitative revisal after lathe finishing.
After having repaired; under the indication of little sensing chip; automatic dressing dish turns to lathe bed inner side to be stopped; on grinding wheel spindle moving direction, do not produce interference with end face grinding abrasive disk; do not affect machine tooling; and little sensing chip is alignd with approach switch, and the position of automatic dressing dish is confirmed, play the effect of safeguard protection.
