Description
technical field:
the utility model relates to a kind of numerical control turnning and milling composite horizontal lathe.
background technology:
although China is that lathe is manufactured big country at present, exists manufacturing process to be partial to low-end situation.China's Machine Tool Industry unfavourable trade balance is unexpectedly up to 113.9 hundred million dollars, and the import volume of increase year after year is growing on and on.The growth of import volume, means China's Machine Tool Industry at present as same puffiness.Cause the main cause of this gap to be, on the one hand, the burst of China's machine tool demand and supply increases, and has restricted the lifting of user's integrated artistic level, has also slowed down the hoisting velocity of the whole manufacture level of machine industry.Be that domestic enterprise's capability of independent innovation is not enough on the other hand, cannot meet the specification requirements such as heavy machine tool single-piece compared with the demand on high product market, the structure problem that Zhe Yeshi China machine tool product exists.The core technology of lathe is digital control system.At present, domestic Ge great machine tool plant, digital control system 100% outsourcing.In this low side level that China is just described in the key technology of lathe or in import is almost relied on completely, therefore, the dynamics of investment of increasing to high-end lathe research and development, the training of personnel, and develop the high-end digital control system that has independent intellectual property right, be that domestic lathe can be broken through the key that import lathe is besieged, the high-end lathe manufacture of Ye Shi China can reach the decisive factor of world lead level.
summary of the invention:
the purpose of this utility model is to provide a kind of numerical control turnning and milling composite horizontal lathe.
above-mentioned object realizes by following technical scheme:
a kind of numerical control turnning and milling composite horizontal lathe, its composition comprises: the lathe bed of installing between front footpost and back leg, main spindle box is installed at described front footpost top, described back leg top mounted tailstock, described lathe bed top installation car turning device, described truning fixture is installed milling cutter in described main spindle box direction, power milling head is installed in side, X-direction stepping motor is installed in described lathe bed, described X-direction stepping motor connects transverse ball lead screw, and described lathe bed tail end is installed Z-direction stepping motor;
described front footpost connects cast iron bracket, and dividing head is installed at described cast iron bracket top, and the input worm screw of described dividing head connects Y-direction stepping motor, and described dividing head connects described main spindle box, and the described main spindle box other end is installed leading screw workpiece;
described tailstock connects described truning fixture.
described numerical control turnning and milling composite horizontal lathe, described power milling head connects independent electric motors.
described numerical control turnning and milling composite horizontal lathe, the main-shaft axis of described power milling head and described lathe bed center line are perpendicular.
the beneficial effects of the utility model:
1. the numerical control transformation that the utility model carries out horizontal lathe, be that with horizontal NC lathe difference original lathe saddle (or electric driving tool post) is replaced by minitype motivation milling head is used for clamping all kinds of handles (rod) shape milling cutter, the main-shaft axis of power milling head and lathe center line are perpendicular, also rotatable 90 ° parallel with lathe center line.Changing power milling head is the structure that lathe saddle (or electric driving tool post) can revert to numerically controlled lathe.
to stepping motor, be directly connected with the input worm screw of dividing head, because the gearratio i=1 of dividing head: 40, so, Y-direction stepping motor rotates 1 and turns, driving dividing head spindle to rotate 1/40 turns, Y-direction stepping motor rotates 40 and turns, can drive dividing head spindle rotate 1 turn cut working shaft-like part decile or not decile face lathe main shaft (Y-direction) do not move, when power milling head clamping cylindrical milling cutter and use milling cutter end face cut, lathe horizontal (X-direction) motion and lathe longitudinally (Z-direction) motion are done single action operation, can carry out the slabbing of different depth size and process.When digital control system, control lathe bed main shaft (Y-direction) and first make rotating operation, remake above-mentioned operation, can carry out axial workpiece decile or the not slabbing processing of decile.
all kinds of keyways of the Milling Process axial workpiece of the utility model setting are same as above-mentioned, and lathe spindle (Y-direction) does not move, and when changing small size cotter mill cutter, can carry out the Milling Process of (different specification size) keyway on axial workpiece axial direction; When lathe spindle (Y-direction) and lathe longitudinally single action or the coordinated operation of (Z-direction), can carry out the Milling Process of (different specification size) groove, skewed slot, helicla flute and arc groove on axial workpiece circumferential surface and other shaped form grooves, cam path.In like manner also can carry out the Milling Process of all kinds of convex shape curvilinear paths in axial workpiece circumference or circumferential plane.
the Milling Process leading screw that the utility model arranges is when the coordinated operation of Z-direction and Y-direction motion, within the identical time, complete respectively pitch value Lt of workpiece and workpiece and rotate 1 while turning the interlock displacement operation of Ly, can interpolation Milling Process wall scroll (uniform pitch or decreasing worm-pitch) helix.When controlling Z-direction, X-direction and Y-direction motion single action or coordinated operation, can process the leading screw of single line (or multi-thread) pitch.Leading screw profile (T shape, rectangle, zigzag or circular arc etc.) shape is guaranteed by milling cutter profile.
the numerical control transformation of the horizontal lathe that the utility model carries out, having expanded under the prerequisite of numerical control milling machining functions, has realized multi-shaft interlocked control, widens and expanded the range of application of numerically controlled lathe, has very strong practicality.
