Main shaft 1, workbench 2, table transmission mechanism 3, guide rail 31, slide block 32, screw pair 33, bearing 34, shaft coupling 35, servomotor 36, assembling framework 4, installed surface 41, channel of chip removal 5, division board 6, planker 7, planker transmission mechanism 8.
The specific embodiment
(embodiment 1)
See Fig. 1, a kind of efficient lathe of the present embodiment, comprises and is arranged on clamping workpiece and driving the main shaft 1 of workpiece rotation, the workbench 2 of arrangement of tool, the table transmission mechanism 3, assembling framework 4, division board 6, planker 7 of mobile power is provided and provides the planker transmission mechanism 8 of mobile power for planker 7 for workbench 2 on machine tool frame.
Main shaft 1 is two, be arranged in parallel, and is provided with three workbench 2, three table transmission mechanisms 3, three plankers 7 and three planker transmission mechanisms 8 around each main shaft 1, thereby main shaft 1 is formed to the gesture of encircling.In order to reduce left and right main shaft, in cutting, produce the mutual interference of vibrations phase, two main shafts 1 can be placed on different lathe bed bases; Or two main shafts 1 are arranged on cast mineral base.On main shaft 1, connecting chuck clamps workpiece, and chuck can be selected air spider or oild chuck, can also be that bar or disc-like are selected the chuck structure that middle part is hollow or middle part is solid according to workpiece simultaneously.
Planker 7 and planker transmission mechanism 8 are arranged at table transmission mechanism 3 bottoms.Each workbench 2 planes equate to the distance in the axle center of corresponding main shaft 1, and each workbench 3 and planker 7 mobile non-interference in its stroke.The moving direction of the moving direction of planker 7 and workbench 2 is the direction of two dimensions, and such as the moving direction of planker 7 is Z-direction, the moving direction of workbench 2 is X-direction, thereby just can be so that cutter can be debugged point-device Working position.
Table transmission mechanism 3 and planker transmission mechanism 8 include guide rail and slide block; The bottom of workbench 2 and planker 7 arranges respectively slide block, and slide block and guide rail are slidably connected.The power part of table transmission mechanism 3 and planker transmission mechanism 8 can adopt screw rod transmission or linear electric motors transmission.When adopting screw rod transmission, as shown in Figure 2, table transmission mechanism 3 comprises guide rail 31, slide block 32, screw pair 33, bearing 34, shaft coupling 35, servomotor 36.Workbench 2 is set on screw pair 33, and servomotor 36 drives screw pair 33 by shaft coupling 35 transmissions, thereby drives the workbench 2 that is equipped with slide block 32 to move along guide rail 31.Planker transmission mechanism 8 adopts the principle of screw rod transmission consistent with table transmission mechanism, just on moving direction, guarantees to be two different dimension directions.Certainly, table transmission mechanism 3 and planker transmission mechanism 8 are without screw rod transmission, and the form of employing guide rail, slide block and linear electric motors.As for specifically how adopting screw mandrel to add driven by servomotor, still adopt linear electric motors to drive, mainly still according to actual conditions, select, if space is enough, can select screw pair that price is lower and the mode of driven by servomotor, and if the peripheral workbench arranging of main shaft is more, while not having space again servomotor to be set, can select to adopt the mode of linear electric motors, in Fig. 1, in upper left, lower-left, upper right, the screw pair that the position of four inclinations in bottom right all adopts and the mode of servomotor, at middle part vertical plane owing to not having position that servomotor is installed, adopt linear electric motors.At each table transmission mechanism 3 and planker transmission mechanism 8 places, need to arrange guard shield and protect, be also convenient to chip removal simultaneously.
As for the selection of knife rest, can one or more gang feed tool rack be set each workbench 2 correspondence; Or the corresponding power cutter tower of each workbench 2.
On assembling framework 4, be provided with a plurality of installed surfaces 41, for installment work platform 2, table transmission mechanism 3, planker 7 and planker transmission mechanism 8.As shown in fig. 1, the corresponding main shaft 1 of assembling framework 4 sets gradually top level---four installed surfaces 41 of upper angled---middle part is vertical---bottom angled, between adjacent installed surface 41 or the angle of the extended line of adjacent installed surface 41 be 135 °, also bottom installed surface inclined angle alpha is 45 °.On the horizontal mounting surface of Tu1Zhong, top, workbench is not set, if necessary, can arranges yet.Between the installed surface 41 of two inclinations that the bottom of assembling framework 4 is oppositely arranged, leave the channel of chip removal 5 for chip discharge.The installed surface 41 of two top water mean places at the top of assembling framework 4 links together.
The lathe of the present embodiment arranges division board 6 in the middle of two main shafts 1, to facilitate between the main shaft of left and right, changes part, certainly, when employing manipulator carries out the exchange of workpiece etc., division board 6 can be set.And another effect of division board 6 is, can also towards the two sides of main shaft 1, a workbench 2 be set respectively at division board 6.Keep at a distance in the bottom surface of the bottom surface of division board 6 and assembling framework 4, the smear metal that the bottom surface height of division board 6 at least makes to be positioned at two workbench, 2 generations about assembling framework 4 bottommosts does not interfere with each other.
When needs regulate Working position, can first planker 7 be moved to the position needing, and then fine setting workbench 2 is to accurate position, then selects suitable cutter.Because every main shaft is all provided with at least 2 workbench, therefore for the processing that needs the complex parts of multi-step process, a workpiece has at least two cutters to carry out machining simultaneously, and working (machining) efficiency improves greatly.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
