Compared with prior art, the beneficial effects of the present invention are：
1st, adjustable boring cutter component of the invention for multilayer boring cutter be applied in combination, it is necessary to the boring of cylinder block top-side into
During the finished surface of different gradients, the length that boring cutter stretches out only need to be pre-adjusted, it is then disposable to complete processing, boring efficiency
High, versatility is high.
2nd, the boring head and rotary shaft of adjustable boring cutter component of the invention are the connected mode in uniform thickness Tri-edge shaft and hole,
Boring cutter has gap when not rotating between boring head and rotary shaft, when boring cutter is rotated, uniform thickness Rhizoma Sparganii rotary shaft energy clamping boring cutter
Disk, it is often more important that, during rotation any point of uniform thickness Tri-edge shaft and hole workpiece be to maintain to the distance at axle center it is constant, from
And ensure that boring head does not deviate by center when rotating, it is ensured that good boring rotary balance, improves the accuracy of boring.
3rd, adjustable boring cutter component of the invention can adjust machined surface by the relative position between regulating boring cutter disk
The depth in the hole of different gradients, realizes the disposable completion of complex part processing, and boring is also improved while improving boring efficiency
Cut the versatility of processing.
4th, adjustable boring cutter component of the invention, installed in the lower section of true boring cutter, is processed by by roughing boring cutter
When, roughing boring cutter first contacts machined surface, then contacts machined surface by true boring cutter, realizes disposable coarse-fine boring processing.

Specific embodiment
The present invention is further described below with reference to specific embodiment：
Referring to Fig. 1, Fig. 2 and Fig. 3, the present invention provides a kind of adjustable boring cutter component on multi-head milling machine, including
Boring head 2, boring bar 1, boring bar 1 are vertically arranged, and one end of boring bar 1 is connected with drive device, are equably opened on the periphery of tool rest
Multiple tool bores 3 vertical with the axis of knife bar are provided with, by the lock screw 8 in boring head 2 perpendicular to the knife footpath direction of boring cutter
Boring cutter is pressed in tool bore 3, multiple boring heads 2 are set with boring bar 1 successively from top to bottom, have between adjacent boring head 2 every
Set 4 so that the spaced setting of each layer boring head 2, boring bar 1 with boring head 2 for uniform thickness Tri-edge shaft is connected with the mode in hole, it is described
Boring cutter with position it is corresponding with the machined surface of cylinder jacket.Multilayer boring cutter be applied in combination, it is necessary to the boring of cylinder block top-side into
During the finished surface of different gradients, the length of boring cutter need to be only pre-adjusted, it is then disposable to complete to process, boring efficiency high,
Versatility is high.And the boring head 2 of adjustable boring cutter component of the invention and the connection side that rotary shaft is uniform thickness Tri-edge shaft and hole
Formula, this connection is compared than the connected mode of common keyway, high with bonding strength, the self-centering under load effect, is protected
The dynamic balancing of axle and part is held, the advantages of transmitting torque is big.And the company in common circular, square or triangular pelvis and hole
Mode is connect, there is gap between bar and hole, the center of rotation after bar rotation can deviate, and reduce machining accuracy.Do not turning in boring cutter
When dynamic, there is gap between boring head 2 and rotary shaft, when boring cutter is rotated, uniform thickness Rhizoma Sparganii rotary shaft energy clamping boring head 2 is heavier
Want, any point of uniform thickness Tri-edge shaft and hole workpiece to the distance radius at axle center is R=54.72- (1600.8464-
73.6cosα)1/2Be to maintain it is constant so that ensure boring head 2 rotate when do not deviate by center, it is ensured that good boring turn
Dynamic balancing, improves the accuracy of boring.
As a further improvement on the present invention, 3 boring heads 2 are set with successively under from lower on boring bar 1.
As a further improvement on the present invention, boring cutter component can change the diameter of boring head 2 according to machined surface demand.Can
So that by the extension elongation of fixed boring cutter, the diameter for changing boring head 2 realizes that batch machining has the machined surface of gradient.Every time
Extension elongation is fixed after need not being measured during upper slitter again, simplifies operation, save time cost.
As a further improvement on the present invention, boring head 2 is in axial direction provided with least one tool bore 3, along boring head 2
Be pressed on boring cutter in boring head 2 by the lock screw 8 of radial direction.By changing boring cutter vertically, hanging down for boring head 2 can not adjusted
In the case of straight distance, the vertical range of quick regulation two-layer boring cutter, so that change the depth of machined surface, practical, operation
Simply.
As a further improvement on the present invention, the one end on boring bar 1 away from drive device is provided with guide pin bushing 5, and guide pin bushing 5 is pressed against
On spacer 4, the outer end pad 6 of guide pin bushing 5 and nut 7 are compressed.
As a further improvement on the present invention, nut 7 is band shoulder nut, plays a part of positioning and fastener, is reduced
Space between device, it is to avoid cause the abrasion that device is unnecessary.
Adjustable boring cutter component of the invention by by roughing boring cutter be arranged on true boring cutter lower section, during processing,
Roughing boring cutter first contacts machined surface, then contacts machined surface by true boring cutter, can also realize disposable coarse-fine boring processing.
