In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with the drawings and specific embodiments, the present invention is described in detail.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Carbide alloy processing parts 1 as shown in Figure 1, its central part is through hole, through hole have one be cut into nibs 2, the main part of described forming hole 2 is cylindrical, and its diameter phi d2 is greater than the through-hole diameter of forming hole 2 both sides, and the distance between the left end face of its left end face and adjacent processing parts 1 is h1, distance between its right end face of its its right end face and adjacent processing parts 1 is h2, the width dimensions of described forming hole 2 is h3, and its port part is truncated cone-shaped, and its frustoconical bevel angle is A °.Because the technique Eligibility requirements of forming hole 2 is: h1, h2 differ 0.02, h3 ± 0.02, φ d2 ± 0.02, A ° ± 0.3 °.
In order to process above-mentioned forming hole 2, the processing unit (plant) of a kind of forming hole as shown in Figure 2 can be adopted to process, and described processing unit (plant) comprises be mutually permanently connected all-in-one-piece emery wheel 4 and pole wheel 5.Specifically: as shown in Figure 3, described emery wheel 4 adopts skive to the concrete structure of emery wheel 4 wherein, its overall cylindrical shape in flat, the axial width h4 of emery wheel 4 entirety is the 35%-65% of the axial width h3 of forming hole 2, and to be diameter be its central part
emery wheel installing hole 41, to be diameter be emery wheel 4 outermost layer
the main grinding face 42 of emery wheel, the two sides of the main grinding face 42 of described emery wheel are taper surface.Grinding is carried out to the both ends of the surface of skive 4 and emery wheel installing hole 41, the axial width dimension of all skives 4 for being ground to nibs 2 is made to reach h4 ± 0.003mm, the circular runout of emery wheel 4 reaches 0.005mm, the taper surface angle of the main grinding face 42 of emery wheel reaches A ° ± 0.2 °, and emery wheel installing hole 41 actual size reaches
As shown in Figure 4, to be diameter be its left end the concrete structure of described pole wheel 5
emery wheel installation portion 52, right-hand member is the pole wheel clamping portion 51 of tapered body shape, and the relatively small end in described pole wheel clamping portion 51 is free end, and pole wheel 5 also arranges stop bit step 53.Carry out grinding to for the emery wheel installation portion 52 be ground on the pole wheel 5 of nibs 2, make its circular runout reach 0.005mm, actual size reaches
emery wheel installation portion 52 arranges threaded joints, emery wheel 4 is connected with the emery wheel installation portion 52 on pole wheel 5, guarantee that between the emery wheel installing hole 41 on emery wheel 4 and the emery wheel installation portion 52 on pole wheel 5 be interference fit, and make its right end face of emery wheel 4 and stop bit step 53 closely connected, finally utilize locking nut 3 and emery wheel installation portion 52 to form screw thread to be flexibly connected and to compress emery wheel 4, thus make emery wheel 4 be fixedly connected with integral with pole wheel 5, as shown in Figure 2.
When utilizing the processing unit (plant) of above-mentioned forming hole to carry out the grinding of forming hole 2, as shown in Figure 5, specifically comprise the steps:
First, clamping is fixed on machine tool chief axis 6 by pole wheel clamping portion 51.In order to ensure processing unit (plant) integral installation clamping fixed after reliability, stability, described pole wheel clamping portion 51 can be designed to bullet, and its relatively small end be free end.
Then, processing parts 1 is being fixed after on clamping to lathe, just according to the technological requirement of h1, h2, processing unit (plant) axially carries out straight reciprocating motion path increment along forming hole 2 can be adjusted, makes the difference between h1, h2 within the scope of the 0.02mm of technological requirement.Axial width h4 due to emery wheel 4 entirety is less than the axial width h3 of forming hole 2, therefore, before grinding, first can carry out trial cut by roughly tool setting, according to the left and right reciprocating stroke amount of the size adjustment emery wheel 4 of h1, h2, usually, repeat through tool setting, the trial cut of 1-2 time and just can ensure that difference between h1, h2 is within the scope of technological requirement.
After trial cut terminates, namely carry out grinding by emery wheel 4 pairs of processing parts 1.In Grinding Process, as shown in Figure 5, first upwards length feed, then traverse feed feed left, next, continue upwards to carry out length feed, then namely carry out traverse feed feed to the right in the other direction, so carry out repeatedly longitudinally back and forth, the grinding of traverse feed, until forming hole 2 is ground to technique qualified size.
Diameter tolerance due to emery wheel installing hole 41 is 0-0.01mm, the diameter tolerance of the emery wheel installation portion 52 on pole wheel 5 is 0.01-0.02, and be interference fit between emery wheel installing hole 41 and emery wheel installation portion 52, thus can ensure that the rotating accuracy of emery wheel 4 clamping on pole wheel 5 is within 0.01mm; Meanwhile, the axial width tolerance of skive 4 is only 0.003mm, thus achieves the interchangeability of skive 4 in Grinding Process, is conducive to the working (machining) efficiency improving forming hole 2.After the grinding of the main grinding face 42 of the emery wheel on skive 4 consumes, only need change an emery wheel 4, and not need to pull down together with pole wheel 5 one pieces, thus save that a large amount of emery wheels 4 is dismantled, the set-up time; In addition, the axial width due to emery wheel 4 is less than the axial width of forming hole 2, can adopt longitudinally back and forth, the grinding method of traverse feed to be to process qualified forming hole 2.Therefore, compared with the processing mode of traditional forming hole, adopt technical scheme of the present invention can complete grinding to multiple forming parts hole after carrying out an aim at tool operation, also without the need to repeating tool setting when changing the processing parts of same size, thus efficiently solve the technical barrier of forming hole mass processing, and save and a large amount of carried out to emery wheel outward finishing time that machine repairs, also save a large amount of grinding tool setting time simultaneously, the processing efficiency of forming hole and qualification rate all can greatly be improved.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, it should be pointed out that all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
