Description
Technical field
The present invention relates to a kind of by claim 1 preamble device and by the method for claim 8 preamble.
Background technology
By means of the grinding workpiece time, blank must have such profile, and it has the surplus of comparing with finished size in the tolerance range scope.Because blank satisfies tolerance range to some extent, usually grinding program designs like this, makes heuristic ground near material, and this causes unnecessary idle stroke (empty grinding), cutting material not at this moment, and this idle stroke requires unnecessary process time.
Particularly in order to make assembled cam shaft, other building blocks of functions of cam and camshaft are processed into blank by the tolerance regulation and are installed on the camshaft.Here form a tolerance range, the appearance profile of the cam/building blocks of function of the not grinding of assembling changes in this tolerance range.This profile is called the blank profile.This blank profile must have grinding allowance.
After assembling, grinding cam, supporting position and other working faces sometimes.At this moment worn grinding allowance.Grinding allowance is essential, so that obtain real grinding skin when process finishing, and guarantees to be not less than theoretical profile (finished product profile).
According to prior art, grinding is undertaken by a plurality of working cycles by this way, makes the control of emery wheel follow procedure very rapidly near the maximum excircle of blank profile possibility under the situation of considering tolerance, then begins grinding process itself.In real grinding process, emery wheel with the amount of feeding of regulation with the rotating speed programme-control of stipulating move to the theoretical size of institute's grinding work piece.This feed motion is relatively slowly carried out, thereby makes the workpiece of institute's grinding unlikely overheated and do not damage emery wheel.According to the difference of layer thickness to be ground, feed speed very fast (corase grind) during beginning slows down (correct grinding, finishing mill) then.When arriving theoretical profile, no longer carry out feeding.Workpiece carries out sparking out.Behind the sparking out certain hour, workpiece just has theoretical size, that is finished size, and finishes grinding process by the rapid return of emery wheel.Here in succession repeatedly feed motion is called a plurality of operations each other.
Comprise axially and the radial feeds (workpiece rotational frequency) and the numerical value of the depth of cut radially for control emery wheel needed program, emery wheel with this depth of cut near workpiece.Wherein there are grinding machine with a main shaft and grinding machine with a plurality of main shafts.
The shortcoming of the known up to now control program that is used for grinding machine is; difference according to the blank overall size; that is according to the difference of the actual grinding allowance of grinding function member not; although emery wheel does not contact with workpiece, still by several 1/10mm sometimes very lentamente near the blank profile of building blocks of function.This process usually is called empty mill in speciality circles.Wherein also different according to the lasting time of the different empty mill of the position of blank profile in tolerance range.Therefore need many unnecessary grinding times in many cases.High quality requirement to reliable process causes in addition, utilizes the margin of tolerance that allows fully.Therefore carry out the sky mill of unnecessary length as a rule.Yet can not abandon empty mill again, have the maximum blank profile that maybe may have permission because always contain the individual pieces blank.
Summary of the invention
The objective of the invention is, a kind of apparatus and method are provided, can be with this apparatus and method to shorten as far as possible for the needed time of finished product profile that has the workpiece of blank profile by grinding with a plurality of operation manufacturings, prevent that simultaneously cracked the or workpiece of emery wheel from crossing the highland heating.

Table 1
The emery wheel feed must be carried out like this, and promptly under any circumstance emery wheel can be with in the maximal rate incision surface of the work used when the emery wheel convergence workpiece.
Therefore according to prior art, shown in table 1 left side, emery wheel reaches outside the envelope curve 18 of the surplus of representing maximum possible.Follow the depth of cut that workpiece revolution emery wheel travels and stipulates, until last feed.Here be till the 7th time, carry out sparking out with the 0mm feed, workpiece is ground to finished product profile 16.According to prior art, 7 feeds mean that total depth of cut is 0.5mm.Total working time is for example about 7 seconds.
But by form as seen, carry out with the speed that is complementary with grinding for the distance feed of 0.15mm, although do not grind off any material at all.This process is called empty mill in the prior art.
As shown in form 1 right-hand part, use method of the present invention, this empty mill is got rid of fully.Feed directly from measured surplus, is here+the 0.35mm place carries out, changes 5 circle back grinding actions again at workpiece and finish.Be about 2 seconds the process time that each cam is saved in described example.
In addition as shown in form 1, the depths of cut that beginning 2 is changeed when adopting the inventive method are big in than prior art.Here represent a kind of good improvement project of the inventive method, wherein feed velocity is adaptive according to surplus thickness.For bigger surplus usually with high feed velocity grinding (corase grind).When little surplus, just reduce feed velocity (correct grinding, finishing mill or sparking out).When corase grind, high feed velocity must be selected like this, i.e. the too big power of unlikely adding on workpiece.Therefore do not cause workpiece overheated.In this embodiment, when surplus is 0.500mm, will starts 4 and change depth of cut 0.400mm, be 0.100mm until surplus, and corresponding power input is made as maximum.If but surplus only is 0.350mm, this depth of cut till the surplus of 0.100mm even can also improve so, at this moment total feed should not surpass original power input.Can adopt the unit interval scrap rate as the yardstick of weighing.
Method of the present invention also provides other important advantages except described advantage.It is too little for example to measure the blank profile can choose building blocks of function before grinding, that is the axle in tolerance range no longer.Even also no longer can become qualified parts, therefore grinding again by continuing the processing axle in this case.Therefore no longer continue the processing waste product, and save required for this reason process time and cost.
Bigger in addition is also advantageous in that, the workpiece that promptly has the surplus that surpasses the largest enveloping curve 18 that allows can not cause and damage ground processing.Therefore can partly or in the time that certain production problem occurs reduce tolerance.
Can determine the blank quality with the statistics width in addition, thus the problem that may occur in can EARLY RECOGNITION process in front.
Though method and apparatus described here also can be used for other members except that assembled cam shaft.The supporting position of that for example can be used to cast or the camshaft, bent axle, Control Shaft and the grinding power transmission shaft that forge.
