Description
Technical field
The utility model relates to a kind of being applied to and in the pressure type shot-peening reinforcement machine small size bore area is carried out the device that shot peening strengthening is handled.
Background technology
It is the difficult problem of shot peening strengthening that little endoporus or aspect ratio reach bigger endoporus shot-peening always, and all requires in the stress peening process all piece surfaces are carried out intensive treatment.Because of can't directly entering aperture inside, the little outer wall straight nozzle in aperture carries out shot peening strengthening.The following several shot-peening modes of the general employing of existing little endoporus shot peening strengthening technology.
First kind is for the little endoporus of endoporus aspect ratio, directly uses straight nozzle, sprays into the method that endoporus is strengthened with certain angle of inclination.The weak point of this method is that it is also comparatively loaded down with trivial details right to operate, and is not suitable for the big endoporus of aspect ratio.During operation, nozzle needs along the circumferential direction and the continuous change location of endoporus, could satisfy endoporus all surface shot-peening.In addition, at nozzle and bore area angle of inclination when excessive, the shot peening strengthening ability a little less than.
Second method is to adopt the high speed blade that endoporus is strengthened, and on blade, blade rotates and clash into repeatedly the part bore area at a high speed to bullet by extraordinary adhesive securement, and this method is applicable to the little processing of diameter, the less endoporus of hole depth.
The third is the reflective shot-peening method of a kind of endoporus shot-peening comparatively commonly used at present.This method is to be provided with in the hole, makes the bullet stream that axially sprays into along endoporus, strengthens the reflecting plate of bore area to injection along the aperture.This method key point is how to control bullet stream and reflecting plate position.At present can only be with front end band reflecting plate, the tubular nozzle that nozzle can not rotate relies on workpiece to rotatablely move along the endoporus axial line, could realize the reinforcement of endoporus circumferential inner wall.And the workpiece rotation is comparatively complicated, has the restriction of workpiece geometries in the application, and accommodation is less.
The weak point of said method, endoporus shot-blast unit integrated level is low, will not rotate to drive etc. integratedly, is not easy to each position endoporus of part is carried out intensive treatment, and working (machining) efficiency is low.
The utility model is further improvement and the development to above-mentioned prior art.
Summary of the invention
The utility model provides a kind of flexible operation, convenience at the problem that above-mentioned prior art exists, and the integrated level height can carry out the shot peening strengthening device of intensive treatment to each position in the aperture.
The technical scheme that its technical problem that solves the utility model adopts is, a kind of Rotoblast intensification device for inner surface of small pores, comprise, the nozzle-end endoporus is provided with the reflective nozzle of reflecting plate, it is characterized in that have on the nozzle and make the flow through aperture of reflecting plate collision break-in ejection of bullet, described nozzle is by coaxial continuous main shaft, with the motor that is assemblied in the main spindle box rearward end drive drive disk assembly mutually interlock rotate, and nozzle endoporus and main shaft inner orifice are connected defeated ball flexible pipe.
The utility model has following useful technique effect than prior art:
The reflective nozzle that the utility model rotates with motor-driven, reflection nozzle spinfunction is integrated on the spindle transmission component of coaxial connection, make the shot peening strengthening mode of the both rotatable also leak free realization endoporus circumferential inner wall that can keep-up pressure simultaneously of nozzle, solved the reflective shot-peening of prior art, nozzle can not rotate, workpiece rotation complicated problems.Using simultaneously can be along the swivel nozzle of aperture axial feed, to workpiece aperture inner surface circumference rotation shot-peening, and then no matter has solved workpiece hole depth size occasion, all can realize the reinforcement problem of whole bore area.Add man-hour, workpiece only needs fixed clamp, keeps overlapping the feeding shot-peening by moving nozzle axial line and workpiece aperture axial line, and along aperture axial line rotation mode, adaptability is strong than existing workpiece, operates more flexible.
The utility model adopts drive disk assembly to be installed on the main spindle box rear end.All in main spindle box one side, more can save the nozzle-end space with respect to drive disk assembly, aperture shot-blast unit and workpiece interference situation are significantly reduced, thereby improve adaptability.Adopt the transmission of band transmission synchronously synchronism good simultaneously, stable drive and simple in structure easy to maintenance.
Whole installation weight is light, and volume is little, and is simple in structure, easy to use.The installing plate that this device is provided with can be fixed in mobile pallet or numerical controlled machinery and realize aperture rotation shot-peening and feeding on hand.The defeated ball pipe joint of quick replacing is set in addition, and its dismounting and fitting operation are easy.This device can with the supporting use of numerical control compressed air shotblasting machine.
