Description
The present invention relates to the technical field of dodging of grinding machine wheel-dresser, the method for grinding wheel avoiding and relevant moving component behind the automatic circulation time trimmer of the particularly a kind of automatic internal surface grinding machine trimming wheel.
Automatic internal surface grinding machine is carrying out normal grinding circulation time, and trimming wheel and grinding work piece hocket automatically.To need finishing behind several workpiece of wheel grinding, at this moment, finishing Pen Association passes through suitable motion mode near emery wheel, to realize the finishing to emery wheel.After finishing was finished, trimmer must get out of the way emery wheel, avoid colliding and causing the damage of the original shape and size of emery wheel at grinding circulation time emery wheel and finishing nib, or the finishing pen was collided with relevant motion parts and damaged.At present, the representative preventing collision method that domestic and international grinding machine wheel-dresser grinding wheel avoiding is adopted mainly contains following two kinds: the first, and lift obforms and dodge method.This kind method is to utilize oil (gas) cylinder activation lever to drive the finishing penholder to realize lifting reverse motion, repairs or dodges out emery wheel near emery wheel from tangential direction and carry out grinding.As shown in Figure 1: trimmer pedestal 1 is fixed on (the automatic circulation time of lathe on the head of a bed, trimmer pedestal and workpiece spindle parts do not have relative motion), when oil (gas) cylinder 7 lower oil cavities connect pressure oil, piston 6 moves upward, thereby make and lift down lever 5 and drive finishing penholders 2 and fall down, make finishing nib 3 realize finishing near emery wheel 4; When oil (gas) cylinder 7 upper oil cavities connect pressure oil, piston 6 moved downward, and lifted down lever 5 drive finishing penholders 2 and lifted, and finishing nib 3 leaves emery wheel 4, plays the purpose of dodging.The second, straight line moves the method for dodging.This kind method is that trimmer itself is with a straight line motion guide rail (or guide pin bushing), drives trimmer together with rectilinear motion before and after the finishing penholder by oil cylinder (or other drive source), make the finishing nib from diametric(al) near or get out of the way emery wheel.As shown in Figure 2: trimmer pedestal 1 is fixed on (the automatic circulation time of lathe on the head of a bed, trimmer pedestal and workpiece spindle parts do not have relative motion), when needs are repaired, drive source 8 drives finishing penholder holder 9 and moves forward to contact emery wheel 4 together with revising nib 3 along guide rail roller 10, emery wheel 4 is realized finishing, after finishing was finished, drive source 8 drove finishing penholder holders 9 and moves to behind the guide rail roller 10 together with finishing nib 3 and dodge out emery wheel 4, realizes the purpose of dodging.In the method for above-mentioned two kinds of trimmer grinding wheel avoidings, the trimmer nib all needs a relative motion with respect to the trimmer pedestal, thereby makes the complex structure of trimmer own, and volume is big, the manufacturing cost height, and its in use reliability is relatively poor.
Purpose of the present invention promptly produces thus, proposes a kind of trimmer nib need not the trimmer for automatic internal surface grinding machine of relative motion with respect to the trimmer pedestal preventing collision method.Adopt this method can make the trimmer structural design simple, volume reduces, and manufacturing cost reduces, and can improve its reliability.
For achieving the above object, the present invention is achieved by the following technical solutions: the trimmer pedestal is fixed on the head of a bed parts, and the trimmer nib does not have relative motion with respect to the trimmer pedestal; During finishing, feed compensation mechanism drives feeding planker (direction of feed during grinding) mobile compensation rate forward, grinds frame drive grinding wheel spindle then and finishes finishing to moving through the finishing nib; After finishing is finished, feed compensation mechanism drive the feeding planker backward (with grinding time direction of feed opposite) return certain distance, finishing nib and emery wheel are got out of the way in diametric(al), begin grinding then.
The present invention is owing to utilize the motion of feed compensation guide rail to replace the motion of existing finishing penholder to realize repairing dodging of point and emery wheel, the parts such as relevant control valve, travel switch, drive source of existing trimmer motion have been cancelled, and the structure of trimmer is simplified greatly, thereby reduced the manufacturing cost of whole lathe.After adopting this method invention, trimmer itself is without any action, and originally the fault that produces because of motion has not existed, so the reliability of trimmer is improved.
The present invention has following accompanying drawing.
