Description
Technical field
The utility model relates to a kind of lathe, is mainly used in the turning processing of thin and long shafts parts such as piston rod, screw mandrel.
Background technology
When the length of shaft-like workpiece and its diameter ratio when (L/d>25), are referred to as slender axles, for example the butterfly disk rotating shaft of the main rotary shaft of the piston rod of oil cylinder, square plansifter, butterfly sheet cylinder separator, leading screw etc. greater than 25.This type thin and long shafts part profile is also uncomplicated, generally adopts lathe turning processing.In turning process; Because its poor rigidity; Under the effect of cutting force, self gravitation, rotary centrifugal force and heat in metal cutting, slender axles are easy to produce flexural deformation, have so just destroyed the accuracy of cutter and part relative motion; Make the slender axles that process produce middle thick, the thin shape in two, have a strong impact on the machining accuracy of part.After slender axles produce flexural deformation simultaneously, also can cause the process system vibration, have a strong impact on the roughness of part.
At present, domestic manufacturer's turning thin and long shafts part adopts engine lathe turning usually, adopts the mode of centre frame or follow-rest to process, and after turning machines, adopts the centreless grinding grinding.This processing method needs constantly adjustment centre frame, tailstock, time-consuming, effort when turning; Surplus after the turning is bigger, and production cost is higher.
Summary of the invention
Therefore, the purpose of the utility model is to provide a kind of lathe that is suitable for slender axles processing, and machining accuracy is high.
The technical scheme that the utility model adopts is:
The utility model slender axles lathe for machining comprises lathe bed, is configured in headstock and tailstock on this lathe bed, and cutter, wherein is provided with to pairing the slender axles anchor clamps on headstock and the tailstock, and said slender axles anchor clamps comprise chuck and the elasticity live center that pairing is used; And mate, be provided with a back rest and a follower rest, this follower rest is installed on the planker that is directed at bed ways, and the orientation axis of orientation axis and said back rest together with said chuck and elasticity live center coaxial line.
According to the slender axles lathe for machining of said structure, adopt installation way during use to workpiece " folder is certain ", and corresponding top be the elasticity live center, can compensate the distortion that workpiece produces because of heating in turning process; Simultaneously, be furnished with centre frame, form the multi-point support of building together; Reduce especially to adopt a follower rest, be similar to follow-rest because of the long distortion that produces of slender axles; Directly compensate for tool pressure, overcome because of tool pressure produces and be out of shape the defective that influences machining accuracy.Thereby, have the higher processing precision of ratio according to the slender axles lathe for machining of said structure.
Above-mentioned slender axles lathe for machining, said follower rest and back rest are the hydraulic pressure centre frame.
Above-mentioned slender axles lathe for machining, said follower rest and back rest are 3 self-centering centre frames.
Above-mentioned slender axles lathe for machining, said cutter are that anterior angle is 15 °, and tool cutting edge angle is 90 ° a sharp knife.
Above-mentioned slender axles lathe for machining, said elasticity live center comprise top be used for installing pivotally this top bearing group, and the disk spring that the bearing rear end is positioned; Wherein said bearing group comprises a thrust bearing at least.
Above-mentioned slender axles lathe for machining, said bearing group also comprises a roller bearing.
Description of drawings
Fig. 1 is the structure principle chart according to a kind of slender axles lathe for machining of the utility model.
Fig. 2 is a kind of structural representation of elasticity live center.
Among the figure: 1. headstock, 2. chuck, 3. workpiece, 4. hydraulic pressure centre frame, 5. ball-screw and driver element, 6. tailstock, 7. elasticity live center, 8. cutter and cutter tower are 9. top; 10. bearing, 11. bearings, 12. disk springs.
The specific embodiment
With reference to the slender axles lathe for machining shown in the explanation accompanying drawing 1; Comprise lathe bed, be configured in headstock 1 and tailstock 6 on this lathe bed; And cutter, wherein being provided with to pairing the slender axles anchor clamps on headstock and the tailstock, said slender axles anchor clamps comprise the chuck 2 and elasticity live center that pairing is used; And mate, be provided with a back rest and a follower rest, this follower rest is installed on the planker that is directed at bed ways, and the orientation axis of orientation axis and said back rest together with said chuck and elasticity live center coaxial line.
Said follower rest and back rest are the hydraulic pressure centre frame, step up rapid and reliable.
Said follower rest and back rest are 3 self-centering centre frames, and centering speed is fast, and centering precision is high.
Said cutter is that anterior angle is 15 °, and tool cutting edge angle is 90 ° a sharp knife, can satisfy the feeding mode of high speed, roughing feed amount and little cutting depth, can improve machining accuracy through the reasonable configuration cutting parameter.
Select 15 ° of anterior angles during turning for use, the sharp knife that tool cutting edge angle is 90 °, the feeding mode of employing high speed, roughing feed amount, little cutting depth, reasonable disposition cutting parameter.
When the utility model adopts the lathe in machining slender axles, employing be the installation way on " folder one top ", a termination of chuck 2 clamping work pieces, another termination adopt elasticity live center 7 to hold out against, and be crooked to prevent the workpiece thermal deformation.
And then during according to above-mentioned machined into workpiece, configuration hydraulic pressure centre frame is as supplemental support on numerically controlled lathe.During the turning slender axles, the hydraulic pressure centre frame can be synchronized with the movement with cutter Z axle (definition bed ways direction), plays the effect of follow-rest.Radial cutting force has been cut down in the use of hydraulic pressure follow-rest greatly, has strengthened the rigidity of processing work, the distortion when having reduced cutting, thus improved the form accuracy and the surface roughness of the processing of silk slender axles, guaranteed thin and long shafts part processing steadily.
Thereby the rigidity when having improved slender axles turning according to said structure has been improved the machining slender shaft performance, has improved machining slender shaft precision and surface roughness; Improved the process of present processing slim axle, thereby enhanced productivity, reduced production costs.
For ease of layout hydraulic pressure centre frame, can be chosen in the process that realizes the high-speed turning slender axles on the full function CNC turning machine.Select 3 self-centering hydraulic pressure centre frames for use, note adjusting the axiality of centre frame and main shaft, tailing axle during installation, in order to avoid influence machining accuracy.
Shown in accompanying drawing 2, said elasticity live center comprise top 9 be used for installing pivotally this top bearing group, satisfy rotational positioning, and, satisfy elastic demand the disk spring 12 that the bearing rear end positions, carry out thermal stretching compensation; Wherein said bearing group comprises a thrust bearing at least, and further, said bearing group also comprises a roller bearing, satisfies the support of complex load, can certainly adopt combination bearing.
