Abstract
The invention discloses a kind of replaceable processing drills.It includes drill body and lengthens handle of a knife, and described lengthening handle of a knife one end is axially arranged with drill bit load hole, and the drill body is removable installed in drill bit load hole.Drill bit load hole bottom is equipped with and lengthens the relief hole being connected to outside handle of a knife.This structure can facilitate drill bit to carry out hot charging.Processing drill is fitted by pyrocondensation mode and is lengthened in handle of a knife, while improving bit change-over efficiency, can effectively improve the precision of drill bit.Have the advantages that simple in structure, easy to use, precision is high, versatile.
Description
Technical field
The present invention relates to machining apparatus fields, are a kind of replaceable processing drills specifically.
Background technology
It is well known that in machining field, drill bit is indispensable basic tool, and drill bit is in part appearance
Through-hole or the cutter of blind hole are processed on the entity components such as face, surface of internal cavity.Influenced by design of part, be located at inner cavity of component or away from
Processing from deep place hole is needed by lengthening drill bit, and normal drill bit in the prior art cannot achieve processing, long range
Aperture processing is higher to the rigid of drill bit, circle bounce, required precision simultaneously.
Invention content
The technical problem to be solved by the present invention is to solve the above shortcomings of the prior art and to provide a kind of replaceable processing to bore
Head, its simple in structure, superior performance, it is easy to use, can be suitably used for deep position aperture, be a kind of processing knife that versatility is stronger
Tool.
To realize the above-mentioned technical purpose, the present invention solves technical problem by the following technical programs：
A kind of replaceable processing drill, including drill body and lengthening handle of a knife, described lengthening handle of a knife one end is axially arranged with brill
Head load hole, the drill body are removable installed in drill bit load hole.
Preferably, drill bit load hole bottom is equipped with and lengthens the relief hole being connected to outside handle of a knife, work as drill body
When being packed into drill bit load hole, the air in drill bit load hole is discharged by relief hole.
After adopting the above technical scheme, this structure can facilitate drill bit to carry out hot charging.Processing drill is filled by pyrocondensation mode
Enter to lengthen in handle of a knife, while improving bit change-over efficiency, the precision of drill bit can be effectively improved.This structure have it is simple in structure,
Advantage easy to use, precision is high, versatile realizes the aperture of deep place by lengthening handle of a knife hot charging interchangeable bit
High-precision processing.On the one hand the normal drill bit range of work is extended, advantageously reduces cost, be on the other hand conducive to raising and add
Work drill bit rigidity, ensures tool precision, improves processing efficiency.
Description of the drawings
Fig. 1 is a kind of a kind of replaceable structural schematic diagram of embodiment of processing drill of the present invention.
Reference numeral in figure is as follows：
1- lengthens handle of a knife；2- drill bit load holes；3- drill bodies；4- relief holes.
Specific implementation mode
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.It is described below and is only used for solving
The present invention is released, is not intended to limit the present invention.
As shown in Figure 1, a kind of replaceable processing drill of the present invention, including drill body 3 and lengthening handle of a knife 1, the lengthening
1 one end of handle of a knife is axially arranged with drill bit load hole 2, and the drill body 3 is removable installed in drill bit load hole 2.
Preferably, 2 bottom of drill bit load hole can be equipped with and lengthen the relief hole 4 being connected to outside handle of a knife 1, work as drill bit
When ontology 3 is packed into drill bit load hole 2, the air in drill bit load hole 2 is discharged by relief hole 4, in hot charging drill bit, can be incited somebody to action
Gas discharge in hole, improves installation effectiveness, ensures installation accuracy.
In the use of the present invention, normal drill bit is lengthened by being mounted on handle of a knife 1, it will be able to which carrying out normal drill bit can not
The high-precision in the deep place aperture of processing is processed.
It these are only preferred embodiments of the present invention, do not constitute any limitation of the invention, all essences in the present invention
Any modification, improvement and the equivalent replacement etc. made in refreshing and principle, should all be included in the protection scope of the present invention.
Claims (2)
