Description
Technical field
The utility model belongs to machining manufacturing technology field, and the lathe that relates generally to a kind of new structure is used for the thin and long shafts part cylindrical is carried out machining with knife system.
Background technology
The processing of thin and long shafts part cylindrical, normally on general horizontal lathe or numerical control horizontal lathe, finish, this equipment is when processing short thin, can guarantee the machining accuracy of part preferably, but when the processing slim axle, because the lathe vibrations are violent, processing back part produces moderate finite deformation, and parts size precision and surface roughness all can't satisfy the product design requirement.
Following two kinds of supporting way are adopted in traditional slender axles processing usually:
The one, place fixed type steady center rest at the slender axles middle part.Because the installation of back rest has hindered carrying out continuously of cutting, the processing of thin and long shafts part cylindrical total length is divided into two sections to be finished, and the secondary location makes and is difficult to guarantee the design accuracy requirement after the part processing;
The 2nd, adopt follow-rest processing.Traditional follow-rest carries out 2 supports at the top and the side of slender axles to part, realization is to the continuous cutting of part, processing back part precision also increases than mode, but the vibration of lathe and the cutter relieving of part during owing to processing, to slender axles only two point-supported follow-rest support zones very easily wear and tear, and this mode is behind positions such as processing slim axle part axle journal and bottom land, and tool damage is very serious.
More than the supporter of two kinds of processing modes be fixed support, and the material of supporter is copper or cast iron easy to wear, after forming sliding friction between the thin and long shafts part of supporter and rotation at a high speed, the supporter serious wear needs regularly to change.
This shows, adopt above dual mode that thin and long shafts part is processed, promptly cannot say for sure to demonstrate,prove part processing precision, can produce bigger processing cost again.
Summary of the invention
The purpose of this utility model is to propose a kind of lathe of new structure with knife system, is used to improve the support stiffness of slender axles in whole process, guarantees the machining slender shaft precision, enhances productivity, cuts down finished cost.
The utility model is taked following technical scheme for finishing the invention task: a kind of lathe of new structure mainly is made of bracing frame and three prop carriers with knife system; Described three prop carriers all have tensile axis and supporter, and tensile axis one end of described prop carrier all is fixedly connected with contiguous block, and supporter is connected on the contiguous block and between supporter and axle by axle and is provided with rolling element; Described three prop carriers are separately positioned on the top, side, lower plane of bracing frame; The tensile axis that is arranged on the prop carrier of bracing frame top, side pass bracing frame and with the bracing frame threaded engagement, its other end of the tensile axis of the prop carrier of support frame as described above top, side connects handle; Constitute tensile axis and under the handle effect, drive the structure that supporter moves relative to part to be processed; Its other end of tensile axis of support frame as described above lower plane upper support carrier is threaded with the bracing frame lower plane, constitutes part to be processed lower support and height adjustable structure, and is provided with the locking nut in addition fastening to tensile axis; The supporter of support frame as described above top, lower plane upper support carrier is symmetrical arranged up and down and is coaxial configuration; Support frame as described above is fixed on the lathe big palette and with big palette and moves.
The lathe of a kind of new structure that the utility model proposes has following beneficial effect with knife system:
1, moves along part axial with cutter with knife system, constantly the part processing position is supported, reduced machine vibration, improved processing stability.
2, supporter and part form rolling friction, and rolling friction has reduced the wearing and tearing of part to supporter;
3, run through whole process with knife system, once finish processing, guaranteed machining accuracy;
4, supporter adopts circular sleeve, the support strength height, and it is convenient to change.
5, when machined part axle journal and escape, reduce tool damage, improve working (machining) efficiency.

Among the figure: 1, handle, 2, tensile axis, 3, contiguous block, 4, axle, 5, needle roller, 6, supporter, 7, part, 8, locking nut, 9, tensile axis, 10, bracing frame, 11, big palette.
The specific embodiment
With embodiment the utility model is further specified in conjunction with the accompanying drawings:
As shown in Figure 1, 2, a kind of lathe of new structure mainly is made of bracing frame 10 and three prop carriers with knife system; Described three prop carriers all have tensile axis and supporter 6, and tensile axis one end of described prop carrier screws in contiguous block 3 and welding, and supporter 6 is connected on the contiguous block 3 and between supporter and axle 4 by axle 4 and is provided with needle roller 5; Described three prop carriers are separately positioned on the top, side, lower plane of bracing frame 10; The tensile axis 2 that is arranged on the prop carrier of bracing frame 10 tops, side pass bracing frame 10 and with bracing frame 10 threaded engagement, the tensile axis 2 of the prop carrier of support frame as described above top, side is threaded with handle 1, rotary handle 1, tensile axis 2 drives supporter 6 and moves relative to part to be processed under handle 1 effect, supporter 6 cylindricals are contacted with the part line, form rolling friction; The tensile axis 9 of support frame as described above lower plane upper support carrier is threaded with the bracing frame lower plane, in order to regulating the height of supporter 6, and is provided with the locking nut 8 in addition fastening to tensile axis; The supporter 6 of support frame as described above top, lower plane upper support carrier is symmetrical arranged up and down and is coaxial configuration; Support frame as described above 10 is fixed on the lathe big palette 11 and with big palette 11 and moves.
Before the processing parts 7, the screw of bracing frame 10 by two M16 is installed on the big palette 11 of lathe, adjust the tensile axis 9 of bracing frame 10 lower plane upper support carriers, the supporter 6 that makes the prop carrier on the lower plane support with part 7 contacts and the axis that makes supporter 6 with after part 7 axis are parallel, tighten locking nut 8 tensile axis 9 can not be moved up and down or rotate; Rotary handle 1, adjust the tensile axis 2 of bracing frame 10 upper ends and lateral support carrier, the axis that the supporter 6 of bracing frame 10 upper ends and side is contacted support and make supporter 6 with part 7 is with after part 7 axis are parallel, be equipped with tensile axis 2 tight, tensile axis 2 can not be moved or rotate, simultaneously with the thin and long shafts part fixed support.
When the supporter 6 on three prop carriers contacts with part 7, the axis that guarantees supporter 6 is parallel with part 7 axis, during design, the prop carrier of upper end, bottom surface and the contact wire of part are departed from part center line 1～2mm to forward and backward both sides respectively, to guarantee the support stiffness of process; Because supporter 6 is line with the part cylindrical and contacts, and forms rolling friction between supporter 6 and part; Rolling frictional resistance is little, so part is also less because of the vibration that resistance produces; Bracing frame 10 underrun screws are installed on the big palette of lathe, in the process, move along the axis of workpiece direction with cutter with knife system, support is followed the tracks of at the part processing position, make supporter 6 be subjected to force direction vertical with part 7, can improve the service life of supporter 6 like this, satisfy the specific (special) requirements of thin and long shafts part profile processing simultaneously.
