Abstract
The utility model provides a punching tool for cross holes of quick-release pins, which comprises a drilling jig, a positioning bolt and a compression screw. A first through hole, a cross through hole and a set screw hole are arranged in the drilling jig; the first through hole consists of an unthreaded hole section and a threaded hole section; a screw rod of the positioning bolt is connected with the threaded hole section of the first through hole in a threaded manner; the cross through hole consists of a second through hole and a third through hole; the central axis of the first through hole is perpendicular to a plane consisting of the central axis of the second through hole and the central axis of the third through hole; the set screw hole is positioned at the position of the unthreaded hole section of the first through hole; the central axis of the set screw hole is perpendicularly intersected with that of the first through hole; and the compression screw is arranged in the set screw hole. The punching tool has the advantages that the same specification of cross holes with different lengths in the quick-release pins can be machined by adjusting the length of the positioning bolt, reinstallation is omitted during hole machining, and after the holes in one direction are drilled, the holes in another direction can be machined only by reversely turning the drilling jig for 90 degrees.
Description
Technical field
The utility model belongs to the boring grab technical field, is specifically related to a kind of drilling tool of quick-release pin cross bore.
Background technology
The quick-release pin is a kind of very practical connector, and it is widely used in the connection between parts in the various frame for movements.In pin connected, all there was corresponding pore structure in quick-release pin rod portion, owing to require the precision in hole higher; And on nonplanar surface, punch, if do not utilize drilling tool, only with operating personnel's experience and feel; Not only efficient is low; The hole quality of beating simultaneously also is difficult to guarantee, guarantee the precision in hole so must use drilling tool that pin rod is punched, but existing drilling tool can only be made a call to a word hole on quick-release pin pin rod; If on quick-release pin pin rod, bore the right-angled intersection hole, existing drilling tool is difficult to guarantee the precision in hole.
Summary of the invention
The purpose of the utility model provides a kind of drilling tool of quick-release pin cross bore, has solved existing drilling tool and on quick-release pin pin rod, has beaten the right-angled intersection hole, the problem that the machining accuracy in hole is lower.
The technical scheme that the utility model adopted is that a kind of drilling tool of quick-release pin cross bore comprises model drilling body, bolt and housing screw; Be provided with first through hole, cross-hole and set screw hole in the model drilling body; First through hole is made up of unthreaded hole section and screwed hole section, and the screwed hole section of the screw rod of bolt and first through hole is through being threaded; Cross-hole is made up of second through hole and third through-hole, and the axis of second through hole and third through-hole intersects vertically and is positioned at same plane, and this plane is vertical with the axis of first through hole; Cross-hole and set screw hole are positioned at the unthreaded hole section place of first through hole, and the axis of the axis of set screw hole and first through hole intersects vertically, and is provided with housing screw in the set screw hole, and both are through being threaded; First through hole, second through hole, third through-hole and set screw hole communicate.
Wherein, an end of second through hole and third through-hole is respectively arranged with drill bushing.
Wherein, be positioned on the bolt screw rod in the model drilling body outside and be with locking nut.
The beneficial effect of the utility model is that in quick-release pin cross bore process, the machining accuracy in hole is high; Through adjusting to bolt length, can process the quick-release pin cross bore of same specification different length series, enlarged the scope of application of these anchor clamps effectively; Add man-hour in quick-release pin cross bore, part need not reinstalled, and after the hole drill of a direction is intact, only needs to get final product just reprocessing other direction after 90 ° of the model drilling body counter-rotatings.
Description of drawings
Fig. 1 is the structural representation of the utility model quick-release pin cross bore drilling tool.
Fig. 2 is the structural representation of the utility model model drilling body.
Fig. 3 is the structural representation of the utility model cross-hole.
Among the figure, 1. drill bushing, 2. bolt, 3. locking nut, 4. model drilling body, 5. housing screw, 6. quick-release pin, 7. first through hole, 8. second through hole, 9. third through-hole, 10. set screw hole, 11. unthreaded hole sections, 12. screwed hole sections.
The specific embodiment
As shown in Figure 1, the utility model provides a kind of drilling tool of quick-release pin cross bore, comprises model drilling body 4, bolt 2 and housing screw 5; As shown in Figure 2, be provided with first through hole 7, cross-hole and set screw hole 10 in the model drilling body 4; First through hole 7 is made up of unthreaded hole section 11 and screwed hole section 12, and the screwed hole section 12 of the screw rod of bolt 2 and first through hole 7 is through being threaded, and is positioned on bolt 2 screw rods in model drilling body 4 outsides to be with locking nut 3; As shown in Figure 3, cross-hole is made up of second through hole 8 and third through-hole 9, and the axis that an end of second through hole 8 and third through-hole 9 is respectively arranged with drill bushing 1, the second through hole 8 and third through-hole 9 intersects vertically and is positioned at same plane; Cross-hole is positioned at unthreaded hole section 11 places of first through hole 7, the plane that the axis of first through hole 7 is formed perpendicular to second through hole 8 and third through-hole 9 axis, and the axis of three through holes intersects at a point; Set screw hole 10 also is positioned at unthreaded hole section 11 places of first through hole 7, and the axis of the axis of set screw hole 10 and first through hole 7 intersects vertically, and is provided with housing screw 5 in the set screw hole 10, and both are through being threaded; First through hole 7, second through hole 8, third through-hole 9 and set screw hole 10 4 communicate.
In that being carried out the hole, quick-release pin 6 adds man-hour; Carry out the coarse adjustment of frock earlier: screw in bolt 2; Tighten locking nut 3, the quick-release pin test specimen that will hole is then packed in first through hole 7, screws in housing screw 5 and compresses quick-release pin test specimen; Drill bit carries out test drilling along the pin rod that drill bushing 1 stretches into second through hole 8 and 9 pairs of quick-release pins of third through-hole test specimen respectively; Qualified until the test drilling of quick-release pin test specimen, the test specimen test drilling is qualified has just explained that also upon mediation is good in the position of bolt 2 in first through hole 7, changes formal processing then over to.Formally add man-hour, quick-release pin 6 is packed in first through hole 7, guarantee that the end of its front end and bolt 2 is close to; Screw in housing screw 5 then and compress quick-release pin 6; After compressing, drill bit stretches in second through hole 8 along drill bushing 1 earlier the pin rod of quick-release pin 6 is holed, after having bored; With 90 ° of model drilling body 4 whole upsets, drill bit stretches in the third through-hole 9 along drill bushing 1 pin rod of quick-release pin 6 is carried out the boring of another side; In a clamping, accomplish twice boring, just cross-hole under boring on the pin rod of quick-release pin 6.
When the quick-release pin 6 to different length punches on pin rod, through positioning of rotating bolt 2, make the punch position of quick-release pin 6 pin rods corresponding with cross-hole, so just can the quick-release pin 6 of different length be punched.After get well corresponding of punch position of quick-release pin 6 pin rods with cross-hole, lock through the 3 pairs of quick-release pins 6 of locking nut of screwing, prevent that quick-release pin 6 is loosening in process.Drill bushing 1 is used to guide drill bit, prevents the deflection of drill bit in process simultaneously.
