Technical field
The present invention relates to mechanical field, a kind of vertical face grinding machine main shaft crushing
Device.
Background technology
Face grinding machine is typically used in Precision Machining, is the plane to workpiece of the end face by emery wheel
Carry out Precision Machining, owing to the required precision of processing workpiece is high, so, abrasive wheel end face quality
Quality, directly influences the machining accuracy of workpiece.
The finishing mode of face grinding machine emery wheel is mainly based on manual trim at present.Dressing process
In, it is manually completing by operator, while adding operator's labor intensity, to behaviour
The skill set requirements of author is the highest, and otherwise the end face of emery wheel is easy to be accomplished middle convex or middle
Recessed shape, affects the machining accuracy of lathe；The trim amount of emery wheel and finishing time bad control；
The abrasive wheel end face shape of every twice finishing has difference, and machine tool accuracy changes greatly.
Summary of the invention
For solving above-mentioned technical problem, it is an object of the invention to provide a kind of accurate face grinding machine certainly
Dynamic trimming device, is arranged on face grinding machine, it is achieved the precise dressing to end face grinding abrasive disk end face,
The end face making emery wheel has higher flatness, meets the processing request of precision workpiece, mainly should
It is used on vertical single, double face grinding machine.Concrete technical scheme is as follows:
A kind of accurate face grinding machine automatic trimming device, dresser main shaft is by a pair angular contact ball axle
Holding and position, be fixed in dresser bore, the upper end of dresser main shaft arranges driven synchronization
Belt wheel, driven synchronous pulley connects active synchronization belt wheel, active synchronization belt wheel by synchronous belt
Being connected with decelerator, described decelerator is connected with servomotor；Servomotor is fixed on motor cabinet
On, motor cabinet arranges adjustment screw for adjusting the degree of tightness of Timing Belt；Under dresser main shaft
End arranges automatic dressing dish；Described automatic dressing dish is semicircle, and circumference 180 degree is fixed with
Polylith rectangle finishing block；Automatic dressing dish pivots about with dresser main shaft, uses rectangle
Emery wheel is repaired by finishing block.
On the cylindrical of described dresser main shaft upper end, little sensing chip is set, described dresser seat is arranged
Proximity switch；Proximity switch can sense little sensing chip and pass the signal along to the control of grinding machine
Center, and judged the rotational angle of automatic dressing dish according to the signal sensed by control centre,
In order to avoid and Wheel Interference.
The quantity of described rectangle finishing block is 8.
On described automatic rest and reorganization dish, multiple groove is set, arranges fixing in the centre of each groove
Block, described fixed block is fixed by bolts on automatic dressing dish, between fixed block and described groove
Rectangle finishing block is set.
The invention have the advantage that owing to automatic dressing dish is semicircle, outside dresser main shaft upper end
Little sensing chip is set on circle, described dresser seat is positioned proximate to switch, is determined by automatically repairing
The angle of whole dish, it is to avoid automatic dressing dish and Wheel Interference；Use rectangle finishing block can be easy to add
Work finishing block；Finishing block fixed form on automatic dressing dish conveniently replaced finishing block.

Detailed description of the invention:
As shown in Figure 1-Figure 3, the dresser main shaft 8 positioning support by angular contact ball bearing,
Being fixed in dresser seat 9 hole, dresser main shaft 8 upper surface connects driven synchronous pulley 5,
Little sensing chip 2 is connected on the cylindrical of dresser main shaft 8 upper end, makes little sensing chip 2 with fixing
About 2mm is transferred in the gap of the proximity switch 1 on dresser seat 9, allows proximity switch 1 energy
Enough sensing little sensing chip 2, dresser main shaft 8 lower surface connects automatic dressing dish 4, connects
It should be noted that to install when little sensing chip 2 aligns with proximity switch 1 during automatic dressing dish 4,
The disk body making automatic dressing dish 4 does not produce dry with end face grinding abrasive disk 7 on grinding wheel spindle moving direction
Relate to, then dresser seat 9 is connected in the lathe bed that grinding wheel spindle is other, fix with screw 6.
Servomotor 16 is connected with decelerator 15, and is first coupled on motor cabinet 12 with screw 6,
Need not tighten, active synchronization belt wheel 17 is connected on the output shaft of decelerator 15, then by motor
Seat 12 is connected to after bed piece, fixes with screw 6；Then, Timing Belt is passed through
10 make active synchronization belt wheel 17 couple together with driven synchronous pulley 5, then with adjusting screw 13
Compensating roller good by Timing Belt 10, tightens screw 6, makes the Timing Belt 10 can be by servo
The rotary power of motor 16 output is forwarded to driven synchronous pulley 5 by active synchronization belt wheel 17,
It is forwarded to automatic dressing dish 4 again by dresser main shaft 8.Finally, by 8 pieces of rectangle finishing blocks
3 are installed on automatic dressing dish 4, set grinding wheel spindle pick feed time, the amount of feeding, repair
Whole number of times, automatic dressing dish rotating speed, grinding wheel spindle rotating speed etc., it is possible to emery wheel is repaired.
During use, dresser seat and motor cabinet need to be fixed on end face grinding machine tool, solid with screw
Reserve, and tightness of synchronous belt is adjusted.
When to crushing, make automatic dressing dish according to conjunction by setting the rotating speed of servomotor
Suitable rotating speed rotates, and grinding wheel spindle is rotating to the timing of automatic dressing dish, quantitatively moves, from
Dynamic conditioner discs often rotates a circle, and emery wheel is once repaired by rectangle finishing block, sets emery wheel
Axle pick feed time, the amount of feeding, finishing number of times, automatic dressing dish rotating speed etc., it is achieved emery wheel
Timing finishing, quantitatively finishing, concordance finishing, high-quality finishing, it is simple to after lathe finishing
Quantitative correction.
After having repaired, under the instruction of little sensing chip, automatic dressing dish turns to inside lathe bed
Stop, on grinding wheel spindle moving direction, do not produce interference with end face grinding abrasive disk, do not affect lathe and add
Work, and make little sensing chip align with proximity switch, the position of automatic dressing dish is confirmed,
Play the effect of safeguard protection.
