Description
Technical field
This use is novel, and what relate to is the cylinder tube manufacture field, and especially a kind of thin-wall long and thin hydraulic cylinder cylinder barrel draws boring machining device.
Background technology
In the prior art, technique known is, oil cylinder is the main execution unit of engineering machinery, and present most of oil cylinder production company normally pushes away boring processing.The advantage of this method is: simple in structure, and material loading and easy to process.But when ips during less than 80mm; Boring bar is elongated, pushes away the boring mode as if employing, and too carefully the not enough meeting generation of rigidity is vibrated, chip removal is difficult, forge a knife easily, cutter life is short, machining accuracy is difficult to assurance, tube wall thickness ununiformity even penetrate tube wall because of boring bar; Therefore during the processing slim cylinder diameter; A lot of producers adopt honing method, but the honing complex procedures, and lose time.This is the existing in prior technology weak point.
Summary of the invention
The purpose of the utility model is exactly not enough to existing in prior technology; And the technical scheme that provides a kind of thin-wall long and thin hydraulic cylinder cylinder barrel to draw boring processing method and device; This scheme has solved problems such as the rigidity that pushes away the boring boring bar and machining accuracy; Can improve the surface quality of cylinder barrel greatly, especially be fit to the hydraulic cylinder cylinder barrel of internal diameter less than 80mm.
This programme is realized through following technical measures: a kind of thin-wall long and thin hydraulic cylinder cylinder barrel draws boring machining device, comprises lathe bed, is arranged on the cold, high pressure radiator cooler of lathe bed one side; End at lathe bed is provided with the headstock that has the first external control case, is provided with the headstock that has the second external control case at the other end of lathe bed, and this programme characteristics are: on lathe bed, also be provided with the hydraulic control carriage; Described headstock is fixedly connected with tapering broaching boring head through pull bar, and described tapering broaching boring head comprises the axle that is arranged on the middle part, and the front end of axle has tapering bootstrap block and the cutter hub that has blade; Side at cutter hub is provided with the adjusting fixed block; The axle of the rear end of cutter hub is provided with drain pipe, and that on the axle of drain pipe rear end, installs successively has splicing sleeve, little cover, preceding ring gear, a back ring gear, and retainer is arranged on the splicing sleeve; Roller is housed in the retainer; For a short time being set on the retainer back, is preceding ring gear and back ring gear above the little cover, is provided with spring and opens pin between described preceding ring gear and the back ring gear; The rear end of ring gear is provided with thrust bearing in the back; Be provided with the guiding support set in the rear end of axle, the afterbody of axle is provided with inlet, and described inlet is communicated with drain pipe through passage.Described cutter hub is three, and three cutter hubs front and back on axle distribute, and mutual angle is 120 degree.Described blade is the RCMT blade.
The beneficial effect of this programme can be learnt according to the narration to such scheme; Owing in this scheme, use drawing-boring machine tool; With the tapering of this programme broaching boring head the hydraulic cylinder cylinder barrel is drawn boring processing, can be common deep hole with car or cold-drawn after disposable the finishing of work that could accomplish with 2-4 operation of honing again.It is dissolved in one to heavy boring, half right boring, right boring and roll extrusion, and rolling and processing reaches more than the Ra0.4 workpiece roughness, and it is about 30% that case hardness improves, and cylinder barrel inner surface fatigue strength improves 25%.Can improve the service life of cylinder tube; And can discharge iron filings timely, help the carrying out of processing, the cold, high pressure radiator cooler provides highly pressurised liquid to lathe; Highly pressurised liquid is gone out through drain pipe, can cool off and in time washes away the iron filings that cutting produces before the roll extrusion the broaching boring head.This shows that the present invention compared with prior art has outstanding substantive distinguishing features and obvious improvement, the beneficial effect of its enforcement also is conspicuous.
