Abstract
A method for exchanging the cutting tool during machining the central hole of crankshaft and its dedicated locking block and reference block are disclosed. Said method includes such steps as using a dedicated locking block to fix mainshaft, using a dedicated reference block with central opening on its front end to axially locate the mainshaft of central drill bit, and detaching said locking block for releasing the mainshaft.
Description
Technical field
The present invention relates to improvement and specific purpose tool thereof, be meant crank axle machining center hole operation cutter replacing method and special-purpose latch segment and reference block especially for crank axle machining center hole operation cutter replacing method.
Background technology
When in the operation of crank axle machining center hole, changing centre drill in the past, the dedicated fixed instrument of no main shaft, adopt hand-held or other instrument fixed main shaft, cause main shaft getting loose or back rotation during fastening centre drill locking nut, be difficult for nut being unclamped or locking, poor stability, hinder hand easily, nut check power is not enough, centre drill in use becomes flexible easily, fractures.Simultaneously for guaranteeing the central hole of the crankshaft dimensional requirement, must adjust the axial installation dimension of centre drill, prior art generally adopts special-purpose measurer to finish the axial location of centre drill, fixed center is bored locking nut then, because centre drill locking nut and main shaft are easy to generate the phenomenon of " working day and night ", so this localization method causes the replacing process cycle of centre drill long, the axial location of centre drill is inaccurate, the single very difficult problem of this operation of finishing.
Summary of the invention
The object of the present invention is to provide a kind of improved crank axle machining center hole operation cutter replacing method, and the latch segment of supporting this method special use and reference block, the axial location of, centre drill short with the replacing process cycle of realizing centre drill accurately, the fastening degree height of centre drill, the purpose of process easy operating.
Overall technology solution of the present invention is:
Crank axle machining center hole operation cutter replacing method, comprise successively axial location, the centre drill locking nut of the centre drill after the dismounting of the getting loose of fixing, centre drill clamping screw, centre drill of main shaft and replacing, the replacing locking positioning, remove the fixing of main shaft; Each operation is respectively in this method:
A, in the fixedly operation of main shaft, an end and main spindle box 7 end faces of latch segment 6 are fixed, adopted concavo-convex the cooperation to fix with main shaft 5 depressions in the surface the other end of latch segment 6;
B, the end offered and the reference block 1 end face roof pressure of the perforate 8 that centre drill 4 front ends are adaptive is fitted in the outer face of the spring cutting ferrule 3 between centre drill 4 and the centre drill locking nut 2, and perforate 8 cooperated with centre drill 4 outer end roof pressure suits, locking centre drill locking nut 2 realizes changing the axial location that rear center bores;
The fixedly operation of c, releasing main shaft is that latch segment 6 is got loose with the concavo-convex stiff end that cooperates of main spindle box 7, pulls down latch segment 6.
The operating process of this method is as follows:
At first fixed locking block 6, reference block 1 is sleeved on centre drill 4 anterior also roof pressures in the outer face of spring cutting ferrule 3, because the effect of centre drill 4 Rear springs, realize the axial location of centre drill 4, pretension centre drill hold-down nut 2, the reference block 1 that gets loose can be finished with spanner or the sleeve pipe that is installed in the spanner rear portion then and change rear center and bore 4 fastening operation.
The concrete structure of latch segment and reference block is in of the present invention:
One end of latch segment 6 and the end face of main spindle box 7 adopt secure fit, and the other end of latch segment 6 adopts concavo-convex the cooperation to fix with main shaft 5 depressions in the surface.
The inside of reference block 1 offers the axial aperture 8 adaptive with centre drill 4 front ends.
Axial aperture 8 is that an end opening is the blind hole of cecum in end face, the other end of reference block 1, or is opened on a kind of in the through hole of both ends of the surface of reference block 1 respectively.
Axial aperture 8 is the reducing hole adaptive with centre drill 4 front ends.
The length of the axial aperture 8 of reference block 1 is to process according to the actual needs of crankshaft center hole dimension, to guarantee that centre drill 4 extends the exact length of spring cutting ferrule 3 parts in the replacing process.
Substantive distinguishing features that the present invention is obtained and significant technological progress are:
1, this method is the improvement for existing crank axle machining center hole operation cutter replacing method, and simplified existing cutter replacing method, easier being guaranteed of axial installation dimension when adopting this method that centre drill is changed, easy to operate, quick, security is good, before having avoided improving the not enough and centre drill that cause of the coupling mechanism force of locking nut in use be easy to generate loosening, problem fractures.
2, latch segment and reference block not only can be controlled the rotation of main shaft, thereby unclamp easily or screw the centre drill locking nut, and the location of the axial installation dimension can realize fast that centre drill is changed the time.
Description of drawings
Accompanying drawing of the present invention has:
Fig. 1 is an overall work principle schematic of the present invention.
Fig. 2 is the structural representation of latch segment.
Fig. 3 is the structural representation of reference block.
The specific embodiment
Below in conjunction with accompanying drawing embodiments of the invention are described further:
The overall work principle of present embodiment and structure are as shown, crank axle machining center hole operation cutter replacing method, comprise successively axial location, the centre drill locking nut of the centre drill after the dismounting of the getting loose of fixing, centre drill clamping screw, centre drill of main shaft and replacing, the replacing locking positioning, remove the fixing of main shaft; Each operation is respectively in this method:
A, in the fixedly operation of main shaft, end of latch segment 6 and main spindle box 7 end faces are adopted bolting, adopt concavo-convex the cooperation to fix with main shaft 5 depressions in the surface on the bolt of the other end assembling of latch segment 6;
B, the end offered and the reference block 1 end face roof pressure of the perforate 8 that centre drill 4 front ends are adaptive is fitted in the outer face of the spring cutting ferrule 3 between centre drill 4 and the centre drill locking nut 2, and perforate 8 cooperated with centre drill 4 outer end roof pressure suits, locking centre drill locking nut 2 realizes changing the axial location that rear center bore;
The fixedly operation of c, releasing main shaft is that latch segment 6 is got loose with the main spindle box 7 concavo-convex stiff ends that cooperate, and pulls down latch segment 6.
One end of latch segment 6 adopts bolting to cooperate with the end face of main spindle box 7, and the bolt of the other end of latch segment 6 adopts concavo-convex the cooperation to fix with main shaft 5 depressions in the surface.
The inside of reference block 1 offers the axial aperture 8 adaptive with centre drill 4 front ends.Axial aperture 8 is for being opened on the reducing through hole of the both ends of the surface of reference block 1 respectively.
