Description
The present invention relates to pneumatic feeding rig, particularly Airfeed peck drill configuration (peckdrill).
Airfeed peck drill configuration has a wide range of applications in aerospace industry, and this is because it has the ability that can accurately get out ganoid boring.Up to now, when drilling deep hole in thick material (hole depth and diameter ratio are 7: 1 or bigger), people think that always Airfeed peck drill configuration is best instrument.
United States Patent (USP) 4123188 discloses a kind of modular design of Airfeed peck drill configuration.In the embodiment of this patent, the pneumatic extended length that feeds formula stepping rig is considered to make the necessary technology of its work.Specifically, think that the bushing type auger spindle that air motor and reduction gearing are housed must be driven by the cylinder that is connected in the auger spindle rear end.In order to control the rig operation, a slave arm is housed in the back of this cylinder, this slave arm is used to be connected with a damped cylinder.Utilize the feed speed of this damped cylinder control auger spindle then towards workpiece.
Because the motion that rotary drilling-head put in and withdrawed from boring is carried out in workpiece, thus importantly the operation strictness of rotary drilling-head is limited in the identical track exactly, otherwise any slight rocking or be offset of drill bit all will cause circle or crooked of boring.Therefore, near hell the time, produce any deflection, just must be limited the stressed of auger spindle and elongation in order to prevent auger spindle.In addition, also thinking should be as much as possible and the central axes of auger spindle along being parallel to line of action of force that the auger spindle direction applies.The length lengthening of the feasible Airfeed peck drill configuration of designing of these restrictions.The performance of the rig that even now is designed is gratifying, but has limited its range of application owing to it is oversize.When being installed to this microscler Airfeed peck drill configuration on the anchor clamps for boring, rig itself will produce a moment arm, the weight of this moment arm and rig combines and will cause anchor clamps to tilt and rig can not normally be holed so, and is special especially true during boring on little or thin workpiece.
Therefore be necessary to provide a kind of like this Airfeed peck drill configuration, it does not have the long like that length of prior art rig, and it just can be used under the condition that does not need big weight anchor clamps.
Below the present invention is carried out general description.
The Airfeed peck drill configuration of a shortening comprises motor and the reduction gearing that is contained in the bushing type auger spindle, and this auger spindle is contained in the cylindrical shell.The tail end of auger spindle has individual piston, so that auger spindle is moved back and forth in described housing.The front end of auger spindle links to each other with a reaction carriage.There is individual transmission arm rear side outside at this housing, and it links to each other with the reaction carriage.A contact arm is housed in the transmission arm rear end, and contact arm can contact with the damped cylinder that the control drill bit stretches into the speed of workpiece.In addition, Airfeed peck drill configuration of the present invention can also comprise that one is mechanically determined from the device of the position of piston rod when each feeding circulation finishes that damped cylinder stretches out and controls the device of the cycle or the time of each step cycle.
By understanding Airfeed peck drill configuration of the present invention better with reference to the accompanying drawings, wherein:
Fig. 1 is the perspective view of Airfeed peck drill configuration;
Fig. 2 is the lateral side view of Airfeed peck drill configuration shown in Figure 1;
Fig. 3 is a perspective view, and it partly shows inner member in the mode of perspective;
Fig. 4 is the partial sectional view of Fig. 1 and Airfeed peck drill configuration shown in Figure 3.
From Fig. 1 and Fig. 2 as seen, Airfeed peck drill configuration 100 is made up of several sections.The front of Airfeed peck drill configuration is one nose 12.As seen, a drill bushing 14 is connected on nose 12 in Fig. 3, so that rig 100 is installed on the anchor clamps (not shown).These anchor clamps link to each other with a workpiece.Circle round drill bit 16 and chuck 18 passes nose 12 operation.Circle round drill bit 16 and chuck 18 by the air motor and the gear mechanism (not shown) driving rotation that are encapsulated in the bushing type auger spindle 20.Auger spindle 20 is assemblied in the cylinder that is formed in the housing 22.So far, just must consider to prevent to contact with the front portion of the cantilever of auger spindle 20.Because this contact will cause problems such as the rough inner surface of processed boring and size inaccuracy.Specifically, near the power that acts on the front end of auger spindle 20 can cause auger spindle 20 deflections.The drill bit of rotation inserts and extracts the deflection that can increase auger spindle continuously from boring, institute's drilling accuracy is descended.Therefore, produce deflection, just must stop any power to be applied to the auger spindle front portion in order to prevent that drill bit from inserting when holing.
Airfeed peck drill configuration 100 of the present invention comprises a reaction carriage 24, and it is connected to the front end of auger spindle 20.Reaction carriage 24 is connected with auger spindle 20 front ends, will guarantee that drill bit 16 by drill bushing 14 supporting can not produce to rock or deflection when stretching into or withdrawing from boring.In addition, can allow auger spindle 20 with respect to the piston biasing, and can not cause that auger spindle 20 rocks or deflection.This biasing makes and the air supply pipe 44 of motor might be arranged on the top of auger spindle 20, and makes it to be arranged in a side of the cylinders retract of housing 22.Air supply pipe 44 is rigidly connected on the biasing thrust piston 38, supplies air into the motor that is arranged in auger spindle 20 when moving back and forth with convenient auger spindle 20.Air supply pipe 44 is also guaranteed the correct orientation of piston 38.Relative with air supply pipe is to retreat to adjust screw 54.The adjustment of screw 54 can be controlled the backstroke of auger spindle 20, therefore, keeps the different length that rotates according to drill bit 16 during auger spindle 20 begins to move forward to it and returns fully, can adjust the retracted position of auger spindle 20.This adjustment can realize that its reason is that screw 54 matches with a valve (not shown) to the CD-ROM drive motor air feed.When the drill bit of rotation during towards workpiece motion s, screw 54 disengages with valve to the CD-ROM drive motor air feed.Because this valve has normal aperture, and makes this revolution.Another advantage of adjustment screw 54 is, the end of drill bit 16 can be by means of the location, end of drill bushing 14, perhaps the length with drill bit 16 or chuck 18 irrespectively is positioned on any desired position, has eliminated unnecessary drill bit running time thus.
A transmission arm 26 is connected on the reaction carriage 24, and is parallel to housing 22 extensions.Transmission arm 26 and reaction carriage 24 seesaw along with the position of auger spindle 20 together.
A contact arm 28 is housed in the end of transmission arm 26, and contact arm 28 stretches out and contacts with piston rod 30 from transmission arm 26, and piston rod 30 stretches out from damped cylinder 32.
Operational circumstances to Airfeed peck drill configuration of the present invention is illustrated below.
Because the structure of Airfeed peck drill configuration 100 of the present invention is small and exquisite, compact, so be easy to it is placed the working site.Optional pistol grip 58 is connected on the housing 22, so that easier grasp and use rig 100.Compressed air can infeed in the rig by in two air inlets any.Specifically, the air inlet 42 at the air inlet 40 of that side by being positioned at rig 100 shown in Figure 2 or the rear portion by being positioned at rig 100 is supplied with compressed air.Path and air supply pipe 44(that compressed air flows through in the housing 22 see Fig. 3-4) arrive in the air motor (not shown) that is encapsulated in the auger spindle 20.Compressed air flows out rig 100 by the gas outlet 46 that is shown in Fig. 2.
After the suitable mechanism that utilizes drill bushing 14 or other is installed in rig 100 on the anchor clamps, press starting switch 34, then the circulation beginning is crept in stepping, and rotary drilling-head 16 moves in the workpiece.The time that rotary drilling-head 16 contacts with workpiece is by the pneumatic logic device (not shown) control that is encapsulated in rig one side.This pneumatic logic device is well-known in this field, and often is used in various pneumatic tools or the pneumatic equipment.
The feed speed of rig 100 is by damped cylinder 32 controls, and damped cylinder 32 is contained in the top of rig 100.Piston rod 30 stretches out from the rear portion of damped cylinder 32, and applies a continuous resistance on contact arm 28.A piston (not shown) is housed in the damped cylinder 32, and this piston is designed to around it around controlled flow of hydraulic fluid.In more perfect damped cylinder, the knob 36 that is positioned at front end can be provided by the resistance that is provided by piston, changes the feed speed of rig thus.Particularly, a very little drag energy improves the feed speed of rig 100, makes rig 100 that drill bit is deeper pierced in the workpiece before withdrawing from from boring.Bigger resistance will make rig 100 that drill bit is pierced in the workpiece before withdrawing from from boring more shallowly.It should be noted that when pneumatic feeding rig withdraws from workpiece contact arm 28 leaves the end of the piston rod 30 that stretches out from damped cylinder 32.That is to say that the air that supplies to piston 38 from housing 22 ends retreats auger spindle 20, the valve (not shown) is blocked up to adjusting screw 54.The pneumatic logic circuit makes air be fed to the rear portion of piston 38 then, thus make auger spindle 20 with the form that resets fast towards workpiece motion s.As seen, piston 38 departs from the central axis of auger spindle 20 from Fig. 3 and Fig. 4, and the area of its outside end face 38a is greater than the area of inner side end 38b.Reset fast and control with contacting of piston rod 30 by contact arm 28.The timing of step cycle is by the control of pneumatic logic circuit, and as previously mentioned, the speed of service of auger spindle 20 is controlled by the resistance size that damped cylinder 32 is provided.
Creep into cycle period in stepping, do not allow piston rod 30 to turn back to the rearmost end position with contact arm 28.The position of piston rod 30 is to retreat the (see figure 4) that controlling organization 46 is determined by one.Retreat the amount of returning of controlling organization 46 limited piston bars 30, and then allow the drill bit 16 that the rotates one section predetermined distance of advancing forward fast at the bottom of the hole of boring.Along with contact arm 28 moves step by step towards workpiece, it finally touches block 48, and block 48 travels forward screw rod 50.A valve (not shown) is housed in the end of screw rod 50, and it sends the signal that drilling operation finishes.A block 52 also is housed on screw rod 50, and this block provides a braking reliably for accurately controlling drilling depth.
The above embodiments only are exemplary, never mean the restriction to design of the present invention or scope.
