Detailed description of the invention
Below in conjunction with drawings and Examples, the application is described in further detail.It is understood that specific embodiment described herein is used only for explaining related invention, but not the restriction to this invention.It also should be noted that, for the ease of describing, accompanying drawing illustrate only and invent relevant part.
It should be noted that when not conflicting, the embodiment in the application and the feature in embodiment can be mutually combined.Describe the application below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
Refer to Fig. 1-Fig. 5, it illustrates the technical scheme of multifunctional boring cutter according to embodiments of the present invention.As it can be seen, multifunctional boring cutter, including: boring cutter bar 5, boring cutter handle 6, adjustment block 4 and cutter head 2, boring cutter handle 6 is for connecting machine tool main shaft 10, and boring cutter bar 5 is arranged on boring cutter handle 6 and can slide relative to boring cutter handle and stretches out or retract.So, boring cutter bar 5 can as bore hole time radius of machining a part, stretch out or retract can regulate radius of machining by sliding relative to boring cutter handle 6, be called coarse adjustment.Further, adjustment block 4 is inserted by the end of boring cutter bar 5, is detachably fixed between adjustment block 4 and boring cutter bar 5, and adjustment block 4 is used for supporting cutter head 2, and cutter head 2 can stretch out relative to adjustment block 4 or retract.So, when processing hole or after completing above-mentioned coarse adjustment, it is necessary to the processing dimension of mating holes can be stretched out relative to adjustment block 4 by cutter head 2 or retract and radius of machining carries out vernier control again, to reduce mismachining tolerance further.
Wherein, (not shown) can being threaded connection between adjustment block 4 and boring cutter bar 5, namely external screw thread is set in adjustment block 4, female thread is set in the end of boring cutter bar 5, completing to fix thus adjustment block 4 being screwed in boring cutter bar 5；When needs separate adjustment block 4 with boring cutter bar 5, adjustment block 4 is back-outed and namely completes dismounting.Preferably, as shown in Figure 1 and Figure 4, the end face of adjustment block 4 is provided with and is perpendicular to the first holding tank 4.1 that the end face of adjustment block 4 extends, the end face of boring cutter bar 5 is provided with and is perpendicular to the second holding tank 5.1 that the end face of boring cutter bar 5 extends, and the first holding tank 4.1 and the second holding tank 5.1 complement each other to form and be available for the fixed space that screw 3 is screwed into.When fixed adjustment block 4 and boring cutter bar 5, the first holding tank 4.1 and the second holding tank 5.1 are aligned formation fixed space, makes screw 3 be screwed in fixed space, adjustment block 4 is fixed on boring cutter bar 5；When needs separate adjustment block 4 with boring cutter bar 5, screw 3 is back-outed and namely completes dismounting.Further, the first holding tank 4.1 and the second holding tank 5.1 can be mutually be arranged in correspondence with multiple, and circumferentially distributed along adjustment block 4 and boring cutter bar 5, so that fixing more firm between adjustment block 4 and boring cutter bar 5.Further, cutter head 2 is to configure the right boring cutter head for Digit Control Machine Tool, it is possible to is applied in the cutter head 2 on Digit Control Machine Tool, is arranged on machine tool by boring cutter bar 5, expands use scope；And, the cutter head machining accuracy of Digit Control Machine Tool is higher, and cutter head 2 is used for machine tool, it is possible to improve the machining accuracy of machine tool.
Refer to Fig. 1-Fig. 2, it illustrates the technical scheme of multifunctional boring cutter according to embodiments of the present invention.As it can be seen, adjustment block 4 is provided with adjusting nut, adjusting nut can rotate relative to adjustment block 4 and stretches out relative to adjustment block or retract, and cutter head 2 is arranged on adjusting nut, and cutter head 2 is provided with blade 1.Wherein, cutter head 2 is provided with blade 1, is completed the processing in hole by the cutter head 2 cutting movement with cutting blade 1.When processing hole or after completing above-mentioned coarse adjustment, it is necessary to boring cutter is carried out vernier control by the processing dimension of mating holes, to reduce mismachining tolerance further.During use, adjusting nut can be turned so that adjusting nut can rotate relative to adjustment block 4 and forward extend out, the fine adjustment direction shown in four-headed arrow shorter in Fig. 2 by spanner, i.e. fine adjustment, thus microboring head 2 is to adapt to the hole of different accuracy requirement.Further, the distance that adjusting nut forward extends out relative to adjusting nut between 0-5mm, and then, the fine setting radius of the cutter head 2 of multifunctional boring cutter is at 0-5mm, it is ensured that the accuracy error in hole is less than 0.015mm.
Refer to Fig. 1-Fig. 2, it illustrates the technical scheme of multifunctional boring cutter according to embodiments of the present invention.As it can be seen, boring cutter handle 6 is provided with chute 6.1, boring cutter bar 5 can slide along chute 6.1, and is detachably fixed with chute 6.1.The relative chute 6.1 of boring cutter bar 5 can be made to stretch out or skid off chute 6.1, to adapt to the hole to be processed of relatively large radius；The relative chute 6.1 of boring cutter bar 5 can also be made to retract or slip into chute 6.1, to adapt to the hole to be processed of small radii.Preferably, the coarse adjustment direction shown in four-headed arrow longer in Fig. 2, the length of chute 6.1 can be 75mm.So, under the cooperation of chute 6.1 and boring cutter bar 5, the radius range of accommodation of the coarse adjustment of multifunctional boring cutter is between 0-75mm.It has been experienced that, multifunctional boring cutter passes through coarse adjustment, it is possible on processing motor bracket WithHole, location.Preferably, the bearing of trend of chute 6.1 and machine tool chief axis 10 direction are vertically arranged, to provide bigger cutting force.Further, after boring cutter bar 5 has regulated along chute 6.1, bolt 7 can be used to be passed and penetrate in boring cutter bar 5 by boring cutter handle 6 top, boring cutter bar 5 is fixed on boring cutter handle 6；And when needs regulate again, it is possible to back-out to take apart boring cutter bar 5 from boring cutter handle 6 by bolt 7.Preferably, as shown in Figure 4, chute 6.1 is distributed multiple along the length direction of boring cutter handle 6, such that it is able to the hole that processing is deeper.And it is possible to arrange boring cutter bar 5 in each chute 6.1, so that can hole to be processed be processed by many boring cutters simultaneously.As shown in Figure 6, axis hole 9 degree of depth of camshaft casing 8 reaches 3200mm, easily occurs the mismachining tolerance that cutting is unstable and causes during cutting, and if able to arrange many boring cutters on boring cutter handle 6 simultaneously, carry out machining, it is possible to making working angles more stable, machining accuracy is higher simultaneously.
Note that screw described herein and bolt not refer in particular to part, part identical with screw and bolt effect in prior art all can apply to the application.
Above description is only the preferred embodiment of the application and the explanation to institute's application technology principle.Skilled artisan would appreciate that, invention scope involved in the application, it is not limited to the technical scheme of the particular combination of above-mentioned technical characteristic, when also should be encompassed in without departing from described inventive concept simultaneously, other technical scheme being carried out combination in any by above-mentioned technical characteristic or its equivalent feature and being formed.Such as features described above and (but not limited to) disclosed herein have the technical characteristic of similar functions and replace mutually and the technical scheme that formed.
