Abstract
The utility model is a quick-release transferring drill bushing used for an automatic feed drill, the quick-release transferring drill bushing consists of two parts of a commutator and a cutting tool drill bushing, the cutting tool drill bushing is connected with the commutator by the quick-release means, and the commutator is provided with an external screw thread which is in bolt joint with an outer sleeve of the automatic feed drill. The quick-release transferring drill bushing can effectively increase the speed for changing the cutting tool and improve the machining efficiency, and reduce the damage to the automatic feed drill joint caused by frequently changing the transferring drill bushing.
Description
Technical field
The utility model relates to machine tools, especially for the quick-release switching drill bushing of auto-feed brill.
Background technology
In machine industry, it is a kind of advanced tools of often using at present that auto-feed is bored, when using auto-feed to creep into capable bore operation, usually the outer sleeve that needs a kind of auxiliary mould that is called the drill bushing of transferring that auto-feed is bored is connected with the workpiece bushing plate, is reached for the effect of auto-feed cutter guiding and location.Existing its version of switching drill bushing as shown in Figure 1, be a kind of tube-in-tube structure of integral body, an end of sleeve is threaded with the outer sleeve that auto-feed is bored, and the lateral wall of sleeve is provided with boss, be used to compress the workpiece bushing plate, the barrel bore size is supporting with the auto-feed cutter.During actual the use,, even process a hole and also will use manyly according to technological requirement, use every cutter all to be needed and the corresponding switching drill bushing of tool diameter different cutters because different cutters need be used in the different hole of processing.The problem that existing switching drill bushing exists is, when changing cutter, must bore whole switching drill bushing and auto-feed fully that dismounting separates, have a strong impact on working (machining) efficiency, simultaneously repeatedly the dismounting meeting is bored auto-feed and the connecting thread of switching drill bushing causes damage, influence the service life of auto-feed brill.
Summary of the invention:
The purpose of this utility model is to provide a kind of quick-release switching drill bushing, in order to overcome deficiency of the prior art.
Quick-release of the present utility model switching drill bushing is made up of adapter and cutter drill bushing two parts, it is characterized in that quick-release is connected between cutter drill bushing and the adapter, and adapter is provided with external connection screw.
During use, the outer sleeve that the external connection screw on the adapter and auto-feed are bored is spirally connected, and the cutter drill bushing is connected fast with adapter and gets final product.
The beneficial effects of the utility model are when changing cutter, only the cutter drill bushing need be unloaded down from adapter soon, change and the supporting cutter drill bushing of cutter, again the cutter drill bushing is connected with adapter and gets final product, avoided whole adapter and auto-feed are bored disengagement, improve tool-changing speed and working (machining) efficiency with this, reduce the frequent switching drill bushing bores the outer sleeve hickey to auto-feed the damage of changing.
Below in conjunction with the embodiment accompanying drawing this application is described in further detail.

Specific embodiment
Quick-release switching drill bushing as shown in Figure 2 is to be combined by adapter 1 and cutter drill bushing 2 two parts.Cutter drill bushing 2 is plugged in the connection chamber 12 of adapter 1, passes through hoodle 3 clampings between cutter drill bushing 2 and the adapter 1.Be threaded (the auto-feed air drill is not shown among the figure) of adapter 1 and the outer sleeve port of auto-feed air drill.
Referring to Fig. 3, adapter 1 contains neck bush 4, external bushing 5 and quick-release ring 6, quick-release ring 6 is socketed in the outside of neck bush 4, external bushing 5 fixes with neck bush 4, the outside, termination of external bushing 5 is provided with external connection screw 17, be used for adapter 1 is connected with the auto-feed brill, two through holes 11 are arranged on the wall of neck bush 4, be inlaid with hoodle 3 in the hole, the diameter of hoodle 3 is greater than the wall thickness of neck bush, this through hole 11 adds the method that man-hour, adopting process closed up and drops out to prevent hoodle 3, the inboard of quick-release ring 6 is provided with the nest chamber 9 supporting with hoodle, quick-release ring 6 is covered with hoodle 3, and quick-release ring 6 can slide on the surface of neck bush 4, makes the inner chamber of neck bush 4 form the connection chamber 12 by hoodle 3 clampings.
In order to limit the sliding scale of quick-release ring 6 on neck bush 4 surfaces, be provided with a positive stop lug boss 8 at the front end place of neck bush 4 outer surfaces, to stop the reach of quick-release ring 6, the other end of quick-release ring 6 is positioned at neck bush 4 and the mezzanine space 10 that external bushing 5 forms, and is provided with a back-moving spring 7 in this interlayer.To positive stop lug boss 8, the madial wall of quick-release ring 6 is pressed to the inner chamber of adapter 1 with hoodle 3 to back-moving spring 7 with quick-release ring 6 top under the normal condition, is stuck in the functions that realize clampings in the card nest 14 of cutter drill bushing toggle 13 just.When changing cutter drill bushing 2, quick-release ring 6 is pushed backward, compression reseting spring 7, make the nest chamber 9 on quick-release ring 6 madial walls be displaced to hoodle 3 places, cutter drill bushing 2 can be extracted from the inner chamber of adapter 1, the toggle 13 of the suitable cutter drill bushing that will change again inserts adapter 1 inner chamber, card nest 14 on toggle 13 is positioned at hoodle 3 places, unclamp quick-release ring 6, back-moving spring 7 resets quick-release ring 6, and hoodle 3 is with adapter 1 and cutter drill bushing 2 clamping of changing again.
Cutter drill bushing 2 shown in Fig. 4 embodiment is hollow structures that contain loop bar 15 and toggle 13, the internal diameter at its loop bar ante-chamber place is the minimum place of whole cutter drill bushing and adapter inner chamber, the internal diameter of loop bar ante-chamber and auto-feed cutter big or small supporting, the connection chamber 12 of the outer end diameter of toggle 13 and adapter neck bush 4 is supporting, toggle 13 is provided with the card nest 14 supporting with hoodle 3, and the internal diameter 16 of loop bar front end is supporting with the cutter of auto-feed (omitting not shown in the accompanying drawing).
