Description

Synchronous grinding machine
Technical field
The present invention relates to a kind of synchronous grinding machine, be used for the surfaces of revolution of grinding axle, for example the axle journal of bearing or cam or bent axle.
Background technology
By the grinding machine at the known a kind of a plurality of supportings position for while grinding bent axle of DE102009024209A1, described grinding machine has the emery wheel group.Here, at the opposite side of bent axle single emery wheel is set with described emery wheel group oppositely, is used for the support component seat is carried out grinding.The support component seat of at first polishing thus.After the manufacturing of support component seat is finished, make single emery wheel move withdrawal, and make support component recline (on the support component seat).Then utilize the polishing of emery wheel group to finish the supporting position.
Summary of the invention
The object of the invention is to, develop a kind of grinding machine of type noted earlier, utilize described grinding machine can reduce the process time of workpiece with respect to prior art.
Described purpose realizes by a kind of grinding machine with feature of claim 1.The theme of each dependent claims consists of favourable form of implementation.
According to a favourable aspect of the present invention, the surfaces of revolution to be ground is assigned on two emery wheel groups, and these two emery wheel groups are arranged on axle both sides respect to one another, thereby the normal force component that acts on the grinding force on the axle is cancelled out each other.Be provided with in addition support component, described support component when grinding with the emery wheel group towards the workpiece feeding, and bear the tangentially cutting force of directive effect on axle.Here need to be for the pre-grinding bearing of support component.
Description of drawings
The below describes the present invention in detail according to embodiment.
Wherein:
Fig. 1 illustrates synchronous grinding machine,
Fig. 2 to 5 illustrates the arrangement form of emery wheel group,
Fig. 6 illustrates the arrangement with support component.
The specific embodiment
Synchronous grinding machine according to Fig. 1 has work spindle 1 and tailstock 2, is used for clamping with one heart and driving shaft 3.For machining shaft 3 is provided with two grinding wheel spindle framves 6,6 ', these two grinding wheel spindle framves can travel at guide 8 with upright slide block 4,4 ' by the cross sliding clock 5 on the frame 7,5 '.Each grinding wheel spindle frame 6,6 ' can 3 feedings along opposite direction towards axle on the direction of X-axis, thereby the normal force component that radially acts on the axle 3 of grinding force cancels each other out.Driving upright slide block 4,4 ' along the Z direction realizes by ball screw framework (Kugelrollspindel) and motor 9.Work spindle 1 also can be arranged on the frame movably by motor 9 ' similarly.In Fig. 1, a bent axle is shown as axle 3.This bent axle utilizes two emery wheel groups 10,10 ' processing simultaneously.Two emery wheel groups 10,10 ' are comprised of a plurality of single emery wheels 13 respectively.All centers to be ground/surfaces of revolution 12 of (zentrisch) can be polished in single procedure of processing and be finished with one heart thus.Particularly, this refers to intermediate support body, axle journal 15 and circumference of flange face 16 in the bent axle 7 shown here.Here spacing and the size of the width of each single emery wheel 13 and their mutual spacings and the surfaces of revolution on the bent axle 12 are complementary.Although emery wheel group 10,10 ' is along main-shaft axis 14, the dislocation of 14 ' direction, the bending of axle 3 is insignificant, because emery wheel group 10,10 ' acts on the opposed side of axle 3.Can also strengthen so identical effect for extremely crooked responsive axle 3, namely have the single emery wheel 13 than the surfaces of revolution more than 12 to be processed.Fig. 2 relates to arrangement form according to claim 3.Here, roughly at the mid point of axle 3, on a surfaces of revolution 12, act on simultaneously two single emery wheels 13,13 '.Fig. 3 illustrates arrangement form according to claim 4,, acts on simultaneously two single emery wheels 13,13 ' here on two surfacess of revolution 12.Processing at camshaft shown in the Figure 4 and 5.Fig. 4 respective rights requires 5 feature, and all surfacess of revolution 12 at axle 3 all act on two single emery wheels 13,13 ' simultaneously here.Last Fig. 5 illustrates arrangement form according to claim 6.Support component 17 shown in Figure 6.This support component is when grinding and simultaneously feeding of single emery wheel 13,13 ', and this moment, tangentially the cutting force of directive effect on workpiece was compensated.Single emery wheel 13,13 ' on directions X in the opposite direction feeding, support member 17 is along the Y-direction feeding.
