The summary description of < machining action: with reference to Fig. 2 ~ 6>
In the crankshaft miling machine 1 formed in the above described manner, saddle 7 moves in the Z-axis direction by the Z-direction feed mechanism 10 shown in Fig. 4.In addition, slide 8 moves in the Y-axis direction by the Y direction feed mechanism 15 shown in Fig. 3.In addition, in the swing driving mechanism 24 shown in Fig. 5 and Fig. 6, when the action by wobbling motor 38 drives ballscrew shaft 31 to rotate, the nut member 35 chimeric with this ballscrew shaft 31 moves in the vertical direction.By this nut member 35 movement in the vertical direction, swinging head 21 with bolster 22 for fulcrum and swinging above-below direction (X-direction) is upper.
And, by the action of the cutter motor 27 shown in Fig. 5, rotary cutter 29 is rotated, and the horizontal axis along workpiece 5 while making rotary cutter 29 revolve round the sun around workpiece 5 (with reference to Fig. 2) by the resultant motion of saddle 7 rectilinear motion in the Z-axis direction (with reference to Fig. 4), slide 8 rectilinear motion in the Y-axis direction (with reference to Fig. 3), swinging head 21 oscillating motion in the X-axis direction (with reference to Fig. 3) moves in the Z-axis direction, thus carries out machining to bearing pin neck 5c, the main shaft neck part 5a of workpiece 5.
It should be noted that, when carrying out the oscillating motion of swinging head 21, nut member 35 describes the motion of the track of linearity in the vertical direction, relative to this, shaft component 23 carries out the motion of the track describing arc-shaped, and therefore directly linking nut member 35 is structurally impossible with shaft component 23.Thus, clamp between nut member 35 with shaft component 23 and shaft component 23 is guided in the Y-axis direction relative to nut member 35 displacement the first rectilinear motion guiding piece 41 freely.Thereby, it is possible to structurally do not link nut member 35 and shaft component 23 with having problems, thus wobble drive power is transmitted swimmingly to shaft component 23 from nut member 35.
The explanation of the action effect of < first embodiment: with reference to Fig. 6 >
In the crankshaft miling machine 1 of the first embodiment, swinging head 21 be made to topple over load F to the Z-direction that Z-direction is toppled over and to be delivered to slide 8 from shaft component 23 via the first rectilinear motion guiding piece 41, nut member 35 and the second rectilinear motion guiding piece 42.
At this, when Z-direction topple over load F be delivered to nut member 35 from shaft component 23 via the first rectilinear motion guiding piece 41 time, Z-direction is toppled over load F and is firmly held gear by two Y direction slide blocks 41b, 41b of two Y direction guide rail 41a, the 41a configured abreast with X-direction (above-below direction) and the total be arranged on sliding freely on each Y direction guide rail 41a.
In addition, when Z-direction topple over load F be delivered to slide 8 from nut member 35 via the second rectilinear motion guiding piece 42 time, Z-direction is toppled over load F and is fixed on the X-direction guide rail 42a on slide 8 and is located at sliding freely on this X-direction guide rail 42a and two the X-direction slide block 42b be arranged in X-direction (above-below direction) firmly hold gear.
According to the crankshaft miling machine 1 of the first embodiment, the Z-direction of swinging head 21 is toppled over load F and is firmly held gear respectively by the first rectilinear motion guiding piece 41 and the second rectilinear motion guiding piece 42.Therefore, in existing crankshaft miling machine 100, the effect that the Z-direction of keep off swinging head 105 topples over load F can be held supplement structure 124 bears by engaging protuberance 105a and sandwiching of sandwiching that guiding piece 123 forms, thus sandwich structure 124 required for can removing in existing crankshaft miling machine 100.Thus, there is the effect that the maintainability of the swing driving mechanism 24 that can improve swinging head 21 is such.
[the second embodiment]
Fig. 7 represents the front view of the knife unit of the crankshaft miling machine involved by the second embodiment of the present invention.In addition, Fig. 8 represents the D-D line sectional view of Fig. 7.
It should be noted that, in the crankshaft miling machine 1A of the second embodiment, in the accompanying drawings to being that same or same component marks identical Reference numeral and omits its detailed description with the crankshaft miling machine 1 of the first embodiment, be described centered by the difference of the crankshaft miling machine 1 with the first embodiment below.
The explanation of the difference of the supporting structure of < ballscrew shaft: with reference to Fig. 6,8>
As shown in Figure 6, in the crankshaft miling machine 1 of the first embodiment, the top of the ballscrew shaft 31 in the swing driving mechanism 24 of swinging head 21 is rotatably freely supported on the gear-box 32 of the upper surface part being fixed on slide 8 via bearing arrangement 33.In addition, the bottom of ballscrew shaft 31 is rotatably freely supported on slide 8 via bearing arrangement 34.In other words, in the crankshaft miling machine 1 of the first embodiment, adopt two supports structure as the supporting structure of ballscrew shaft 31.
On the other hand, as shown in Figure 8, in the crankshaft miling machine 1A of the second embodiment, the top of the ballscrew shaft 31 in the swing driving mechanism 24 of swinging head 21 is rotatably freely supported on the gear-box 32 of the upper surface part being fixed on slide 8 via bearing arrangement 33, on the other hand, its underpart is not supported by the bearing arrangement 34 arranged in the crankshaft miling machine 1 of the first embodiment, and the lower end side of ballscrew shaft 31 is free end state.In other words, in the crankshaft miling machine 1A of the second embodiment, adopt cantilever support structure as the supporting structure of ballscrew shaft 31.Thereby, it is possible to form open space in the below of ballscrew shaft 31.
The explanation of < slide groove portion: with reference to Fig. 7 >
And, as shown in Figure 7, in the crankshaft miling machine 1A of the second embodiment, the slide groove portion 60 of the chip that the lower end side of the ballscrew shaft 31 in slide 8 is formed with the machining for discharging accompanying rotation cutter 29 and produces.This slide groove portion 60 has the inclined plane 60a towards lathe bed 2 side direction inclined downward.
So, the chip that the end portion to ballscrew shaft 31 flies to falls along the inclined plane 60a of slide groove portion 60 under gravity, and discharges to the inside of lathe bed 2.It should be noted that, the chip of discharging to lathe bed 2 inside is transported outside lathe by not shown chip discharging device.
The explanation of the action effect of < second embodiment: with reference to Fig. 3,7>
In the two supports structure (with reference to Fig. 3) of the ballscrew shaft 31 adopted at the crankshaft miling machine 1 of the first embodiment, worry that the attachment chip be piled up on the bearing arrangement 34 of downside hinders the down maneuver of nut member 35.
On the other hand, in the crankshaft miling machine 1A of the second embodiment, as shown in Figure 7, the supporting structure of cantilever support structure as ballscrew shaft 31 of the bearing arrangement 34 that downside is not set is adopted.Further, in slide 8, the slide groove portion 60 of chip discharge is formed at the lower end side of ballscrew shaft 31.
According to the crankshaft miling machine 1A of the second embodiment, certainly the action effect same with the crankshaft miling machine 1 of the first embodiment can be obtained.And then, according to the crankshaft miling machine 1A of the second embodiment, the undesirable condition of the down maneuver of the nut member 35 caused because of chip can be prevented in advance.
Above, although be illustrated crankshaft miling machine of the present invention based on multiple embodiment, but the present invention is not limited to the structure described in above-mentioned embodiment, suitably can combines structure described in each embodiment etc., in the scope not departing from its purport, suitably change this structure.
