Description
Technical field
The invention belongs to automation drilling tool technical field, be specifically related to a kind of high rigidity large wire diameter automatic feeding drill unit.
Background technology
Above mentioned high rigidity refers to that whole drill unit has good rigidity, there will not be severe vibration in the course of the work and be able to safeguard work stability and then ensure the crudy of drilled turning work piece, ensureing the reliability of drill unit self and the service life in the reasonable time simultaneously.The concept in aforesaid large footpath refers to that drilling is implemented in the large diameter hole be suitable for workpiece.
Technical information about auto-feed drill unit can be seen in disclosed Chinese patent literature, as CN201529917U(power head mechanism of rotor machining system), CN201744890U(power head for digital control hole drilling), CN202825375U(auto-feed borehole chasing bar), CN202270999U(pneumatic type drill unit) and CN101797652A(Pneumatic high-power drill unit), etc.Typically as " the servo feed drill unit structure " of invention patent mandate notification number CN103317159B recommendation, the achievement part of this patent formula is: owing to have employed servo feed controlling organization, thus to have abandoned in first technology if aforementioned CN202270999U and CN101797652A is using compressed air as power source, eliminated and provide compressed-air actuated auxiliary equipment as air compressor machine or similar device; Accurately control because servo feed controlling organization can carry out journey to F.F. stroke and work, thus both can ensure the drilling quality to workpiece, and effectively can ensure drilling cutters again; Owing to there is the little strong point of noise relative to using compressed air for the feed mechanism of power source, the operating environment in work pieces process place thus can be improved; Due to accurately stroke can be controlled, thus without the need to artificially repeatedly adjusting; Due to can with PLC(programmable controller) realize electrical control and be connected, thus there is desirable automation effect.To this can specifically see this patent the 0002nd section, description, the 0015th section and 0019 to 0035 section.
But still there is the following shortcoming needing improvement badly in aforementioned CN103317159B: one, due to axle sleeve, (patent claims outer tube, as follows) upper end be fixedly connected with travelling carriage (patent claims sliding shoe) by a tediously long slip cap Connection Block, thus at leading screw clockwise or counterclockwise movement and drive travelling carriage downlink or uplink, and and then drive axle sleeve to correspondingly in process that is lower or that move upward by travelling carriage by aforementioned tediously long slip cap Connection Block, because being rigidly connected of axle sleeve is lost rationally and stability of causing its motion is difficult to the requirement that meets the expectation, and whether stablizing of axle sleeve upper and lower displacement campaign can the contraposition stability of sleeve pipe and the splined shaft driven by splined shaft is in transmission connection in the inner have a direct impact, final impact is arranged on splined shaft and is in transmission connection the drilling cutters of lower end of sleeve pipe to the quality of workpiece drilling, they are two years old, the process of ordering about guide screw movement due to servo feed controlling organization is: driven the drive (patent claims the 3rd drive) be fixed on the servo motor shaft of servomotor by servomotor, the drive (patent claims the 4th drive) being fixed on leading screw upper end is driven to drive guide screw movement by this drive through driving-belt (patent claims the second driving-belt) again, thus the speed of guide screw movement is restricted on the one hand, the precision of leading screw upstream or downstream is difficult to ensure on the other hand, and owing to employing two drives (being synchronous pulley) and the driving-belt (Timing Belt) for linking these two drives, thus not only power transmission loss is large, and cause its volume relatively huge, be unfavorable for that the overall volume of auto-feed drill unit develops to miniaturization, they are three years old, realize being in transmission connection due in the transmission case chamber that the upper end of screw mandrel need probe into transmission case, no matter so be that aforesaid servo motor shaft or the upper end of leading screw all need to be supported on rotationally on transmission case by the corresponding bearing block be arranged on the diapire of transmission case, thus cause the complex structure of transmission case, increase difficulty of processing, they are four years old, cavity due to transmission case holder is open type cavity, thus be unfavorable for protecting covering of leading screw, travelling carriage and splined shaft, that is because leading screw, travelling carriage and splined shaft are in open state, subject to trifle in the world and foreign matter invasion and attack on the one hand, lose security on the other hand, then damage sight on the one hand, they are five years old, because travelling carriage is in relatively isolated state in the cavity of transmission case holder, and between the inwall of the cavity of transmission case holder (sidewall), there is not the slip cooperating relationship of rigidity namely, thus drive fast in the process of its upstream or downstream at leading screw, the kinetic stability of travelling carriage and reliability are all difficult to abundant guarantee, although the guide pillar be slidably matched for the middle part of length direction of travelling carriage that patent provides to the kinetic stability of travelling carriage and reliability helpful, but the function singleness of guide pillar, only play travelling carriage upper and lower displacement guide effect, and be not enough to play the effect touched with roof that the is cavity of transmission case holder or diapire that is that avoid travelling carriage likely to occur.
