Detailed description of the invention
In the following description, for purposes of illustration, in order to provide the complete understanding to one or more embodiment, many details have been set forth.But, clearly, also these embodiments can be realized when there is no these details.In other example, one or more embodiment for convenience of description, known structure and equipment illustrate in block form an.
Come below with reference to accompanying drawings to be described in detail according to each embodiment of the present utility model.
Fig. 1 illustrates the stereogram according to vibrocutting cutter of the present utility model.Fig. 2 illustrates the perspective view according to vibrocutting cutter interior structure of the present utility model.As shown in Figure 1, cutter head 1, submissive hinge 2, cutter hub 3, piezoelectricity fold stack driver 4 and blade 7 is comprised according to vibrocutting cutter of the present utility model.As shown in Figure 2, cutter head 1 is connected by submissive hinge 2 with cutter hub 3, and cutter head 1 is positioned at above cutter hub 3.Have groove in cutter hub 3, piezoelectricity fold stack driver 4 to be arranged in this groove and to be compressed by pre-tightening mechanism and cutter head 1, when piezoelectricity fold stack driver 4 is energized vibration, cutter head 1 can be driven to vibrate.As shown in Figure 2, groove is arranged on inner relative with submissive hinge 2 side of cutter hub.
Further, the pre-tightening mechanism of vibrocutting cutter of the present utility model comprises cushion block 5 and screw 6.As shown in Figure 2, cushion block 5 is arranged between bottom portion of groove and piezoelectricity fold stack driver 4, its upper end contacts with piezoelectricity fold stack driver 4, the part of cutter hub 3 below groove offers the screw coordinated with screw 6, screw 6 compresses cushion block 5 through this screw, thus cushion block 5 and piezoelectricity fold stack driver 4 are compressed.Owing to adopting screw pretension, structure is simple, number of parts is few, and therefore vibrocutting cutter of the present utility model can realize rapid pretension.
Further, cutter head 1, submissive hinge 2 and cutter hub 3 can integrally be processed, and without the need to assembling, therefore the first natural frequency of vibrocutting cutter of the present utility model is higher, and operating frequency can bring up to higher scope.And adopt the form of one processing can avoid and that cause fault insecure due to the connection between cutter head 1 and submissive hinge 2 or between submissive hinge 2 and cutter hub 3 in use procedure in the future.
Fig. 3 illustrates that cutter is at the schematic diagram adding cutting-in in man-hour direction, direction of feed and cutting speed direction.In figure 3, x-axis (i.e. the axial direction of cylindrical work) represents direction of feed, y-axis represents cutting speed direction, and z-axis represents cutting-in direction.
Fig. 4 illustrates according to vibrocutting cutter of the present utility model stereogram in the other directions.As shown in Figure 4, according to the cutter hub 3 of vibrocutting cutter of the present utility model, there are four sides.Four sides of cutter hub 3, the i.e. front surface (a surface) of cutter hub 3 and rear surface (surface relative with a surface), upper surface (b surface), lower surface (surface surperficial relative with b) in the diagram.Wherein, the front surface of cutter hub 3 and rear surface form a pair clamping face (the first clamping face), and upper surface and lower surface form a pair clamping face (the second clamping face).When cutting tool passes through the first clamping face clamping of cutter hub 3, cutting tool is in the first clamping direction.When cutting tool passes through the second clamping face clamping of cutter hub 3, cutting tool is in the second clamping direction.That is, according to vibrocutting cutter of the present utility model, there are two clamping directions.
In one embodiment, upper surface and the lower surface of cutter hub 3 are parallel to each other, and front surface and rear surface are parallel to each other, and the first clamping face is vertical with the second clamping face.When piezoelectricity fold stack driver 4 drives cutter hub 3 to vibrate, cutter hub 3 can under the driving of piezoelectricity fold stack driver 4 with the parallel plane plane of a in do around fixing point (such as, the tie point of cutter hub 3 and submissive hinge 2) vibration.
Therefore, when cutting tool passes through the first clamping face clamping of cutter hub 3, the front surface (a surface) of cutter hub 3 is parallel with xz plane, cutter head 1 does the vibration around fixing point in xz plane, and cutter head 1 has oscillating component respectively in cutting-in direction (i.e. z-axis direction in Fig. 3) and direction of feed (i.e. x-axis direction in Fig. 3).Now, owing to having oscillating component respectively in cutting-in direction and direction of feed, therefore can improve working surface quality, suppress the wearing and tearing of blade 7
When cutting tool passes through the second clamping face clamping of cutter hub 3, the front surface (a surface) of cutter hub 3 is parallel with yz plane and upper surface (b surface) is parallel with xz plane, so cutter head 1 does the vibration around fixing point in yz plane, therefore cutter head 1 has oscillating component respectively on cutting-in direction (i.e. z-axis direction in Fig. 3) and cutting speed direction (i.e. y-axis direction in Fig. 3).Owing to having oscillating component respectively on cutting-in direction and cutting speed direction, therefore cutting force can be reduced.
Owing to having two clamping directions according to vibrocutting cutter of the present utility model, can need to select suitable clamping direction according to processing.Therefore, according to vibrocutting cutter of the present utility model, there is the scope of application widely.
Fig. 5 illustrates according to the view of vibrocutting cutter clamping of the present utility model on lathe capstan head.As shown in Figure 5, the size corresponding with conventional tool can be had according to vibrocutting cutter of the present utility model, therefore directly on lathe capstan head, and can be suitable for the processing of cylindrical turning, facing, car chamfering, bore hole etc. by clamping.Due to according to cutter of the present utility model can directly clamping on lathe capstan head without the need to being installed by clamper, therefore the miniaturization (avoiding keeping off cutter) of cutter can be realized, because cutter hub of the present utility model adopts integration processing, therefore part is less has higher operating frequency.Such as, the single order vibration frequency of vibrocutting cutter of the present utility model is 4000Hz, and therefore operating frequency can bring up to 4000Hz in theory.
Although disclosed content shows exemplary embodiment of the present utility model above, it should be noted that under the prerequisite not deviating from the scope that claim limits, can multiple change and amendment be carried out.In addition, although element of the present utility model can describe or requirement with individual form, also it is contemplated that to have multiple element, is individual element unless explicitly limited.
