Abstract
The utility model relates to a vibration cutting device and belongs to technical field of mechanic manufacturing, which is characterized in a vibration drilling and reaming device installed at interface between shank and tail-holder and an eccentric cam cased on an eccentric shaft and located inside the vibration drilling and cutting device. The eccentric shaft is connected with a motor, meanwhile, frequency can be adjusted within the range from 0 to 100 HZ and amplitude of sine vibration can be interruptedly adjusted within the range from 0.10 mm to 0.32 mm. Sizes of work piece can be machined vary from diameter 25 and length 5000 to diameter 48 and length 2000 (diameter of hole*length). 0.02 mm per 300 mm linearity of drilling can be achieved and surface roughness less than Ra 1.6 on machined surface can be reached. Deep score mark can be eliminated on reamed surface and surface roughness is less than Ra 0.8. The control system of low-frequency vibration drilling and reaming can set up, calculate, save and select parameters of vibration drilling and reaming, as well as can monitor load at any time during cutting. Having advantages of good machining quality and relatively high machining efficiency, the utility model has bright future of popularizing and application.
Description
One, technical field
The utility model relates to a kind of vibration cutting device, belongs to mechanical manufacturing field.
Two, background technology
The vibrocutting technology is a kind of new cutting process that grows up since the 1950's, vibrocutting is compared with common cutting, having a significant effect aspect reduction cutting force and the heat in metal cutting, especially having the incomparable technological effect of common cutting aspect difficult-to-machine material processing and the Precision Machining.
1, the subject matter of Small-deep Hole drilling processing existence
(1) chip removal difficulty.The smear metal that common gun drilling produces easily produces stifled bits for bigger volume is considered to be worth doing, elongated helical form smear metal in the working angles.Because chip removal is not smooth, causes problems such as drill edge breakage, endoporus scuffing easily, even working angles can not normally be carried out.
(2) arbor stiffness is poor.Because the deep hole draw ratio is big, drilling rod is very long, even the support and the guiding of knife rest are arranged, all can produce unstability when big or load increases when the amount of feeding; Knife rest and main shaft decentraction, when there is error in the workpiece centering, drill bit easily takes place during drilling wander off, causes linearity overproof.
2, the subject matter of Small-deep Hole ream processing existence
(1) chip removal difficulty.Because the smear metal that common ream produces is elongated helical form, the chip removal difficulty is easy to generate obstruction; Particularly when smear metal is wrapped on the cutter hub, causes the cutter hub torsional deflection easily even twist off.
(2) easily produce built-up edge.Because the machined surface that is created in of built-up edge has formed ditch dug with a plow and squama thorn, have a strong impact on the quality of finished surface during common ream.
Three, summary of the invention
The technical problem of solution of the present utility model is: a kind of steady quality, working (machining) efficiency height are provided, and chip removal is unimpeded, is difficult for making drill edge breakage, endoporus to scratch, and can make working angles Small-deep Hole vibration smoothly drilling and reaming device.
Technical solution: the utility model vibration drilling and reaming device is installed in knife bar and tailstock interface, in the vibration drilling and reaming device eccentric wheel is housed, and eccentric wheel is sleeved on the eccentric shaft, and eccentric shaft is connected with motor.
The utility model can be according to actual processing conditions, select vibration parameters (frequency, amplitude, frequency and workpiece rotational frequency ratio) and cutting parameter (speed of mainshaft, the amount of feeding), can control the size and the shape of smear metal, form how much chip breaking and not exclusively how much chip breaking, guarantee that the working angles chip removal is unobstructed, improve machining accuracy, surface quality and production efficiency simultaneously.Solved Machining Small-deep Hole quality instability, problem that working (machining) efficiency is low, had important impetus, had good popularizing application prospect improving the Small-deep Hole technological level.
