Description
Technical field
The present invention relates to a kind of simple and easy keyhole and counter boring depth limiting device, belong to mechanical drilling techniques field.
Background technology
Aircraft surfaces covering is connected with fuselage mainly through rivet, and skin-surface has the rivet hole of taking measurements greatly and differing.During the making of skin-surface rivet hole, not only needing carries out holing also will carry out aperture counter boring to skin-surface.Because the making of skin-surface rivet hole must be carried out aboard, thus machine tool can not be used to process rivet hole, pneumatic drill by hand can only be made to carry out boring and aperture counter boring, and the rivet hole counter boring degree of depth is crossed deeply or mistake is shallow all will affect aircraft surfaces quality and flight safety.Adopted manual operations to use counterbit to carry out aperture counter boring during the counter boring of skin-surface rivet hole aperture, nest is difficult to control deeply, and part rework rate is high, and the production cycle is long, and cost is high in the past.
Summary of the invention
In order to solve the problem, the invention provides a kind of simple and easy keyhole and counter boring depth limiting device.The present invention can solve piece surface boring very well or counter boring depth dimensions is crossed dark or crosses shallow problem, particularly pneumatic drill boring hand-manipulated or counter boring depth problem.
A kind of simple and easy keyhole and counter boring depth limiting device, its structure is primarily of main shaft, lining, pin, spring, adjusting sleeve, positioning sleeve, rivet, screw, steel ball composition, lining by screw on main shaft, and steel ball is established between lining and main shaft, the thread segment of positioning sleeve and the lining of main shaft are installed together by screw thread; One end of adjusting sleeve is by rivet interlacement positioning sleeve, and the other end of adjusting sleeve, by pin connecting bushing, arranges spring between adjusting sleeve and positioning sleeve.
Before using by with stopping means with the use of target drill and special counterbit be contained on main shaft, then spring is contained in adjusting sleeve inside, and be contained on the main shaft of the good target drill of device and special counterbit together, finally be contained on main shaft by positioning sleeve, positioning sleeve is linked together by the lining of screw thread and main shaft.
Before part processing, the target drill that selection size is suitable and special counterbit, come keyhole and the counter boring degree of depth by rotating positioning sleeve.After treating that depth adjustment is good, rivet in adjusting sleeve is connected with the pin on lining with the U-type groove on positioning sleeve with U-type groove by extrusion spring by adjusting sleeve respectively, thus make main shaft, positioning sleeve become as a whole with adjusting sleeve, add and main shaft is contained on drilling machine man-hour and can processes.
Financial cost has been saved in this invention, accelerates process velocity, avoids piece surface boring or the counter boring degree of depth is crossed dark or crosses shallow phenomenon, enhances productivity, ensure that Product Precision and quality requirement.

Detailed description of the invention
As shown in Figure 1, stopping means comprises main shaft 1, lining 2, pin 3, spring 4, adjusting sleeve 5, positioning sleeve 6, rivet 7, screw 8, steel ball 9, lining 2 passes through screw 8 on main shaft 1, and steel ball 9 is established between lining 2 and main shaft 1, the thread segment of positioning sleeve 6 and the lining 2 of main shaft are installed together by screw thread; One end of adjusting sleeve 5 is by rivet 7 connecting positioning sleeve 6, the other end of adjusting sleeve 5, by pin 3 connecting bushing 2, arranges spring 4 between adjusting sleeve 5 and positioning sleeve 6, spring 4 is by positioning sleeve 6 extruding place compressive state, be used for supporting adjusting sleeve 5, thus play stationary positioned cover 6 effect.
As shown in Fig. 2,3,4,5, positioning sleeve 6 one end is provided with internal thread, and is provided with scale at outer surface, and internal thread is used for being connected with lining 2, and scale is used for adjusting drilling depth and the counter boring degree of depth.Positioning sleeve outer surface arranges U-type groove and is used for and the rivet interlacement in adjusting sleeve 5.
As shown in Figures 6 and 7, rivet is equipped with in adjusting sleeve 5 inner surface one end, and the other end is provided with 24 U-type groove.Rivet is used for connecting positioning sleeve 6, and U-type groove is used for the pin on connecting bushing 2, and U-type groove both sides inwall is used for being connected with spring 4, plays and supports Compress Spring effect.Adjusting sleeve 5 plays connection and stationary positioned overlaps 6 and lining 2.
Method of processing parts is:
The first step: the degree of depth according to hole to be processed or nest selects the drill bit suitable with stopping means size or counterbit, and is arranged on main shaft by drill bit or counterbit;
It is inner that spring 4 is loaded adjusting sleeve 5 by second step, and be together arranged on and install on the lining 2 of drill bit or counterbit (front lining
2by screw and main shaft
1install as a whole);
3rd step, is arranged on lining by positioning sleeve 6
2on.First by positioning sleeve in installation process
