Description

Anti-skidding Quick-change drill bush
Technical field:
The utility model belongs to field of machining, more specifically to the anti-skidding Quick-change drill bush of one.
Background technology:
Many machine components there is through hole, the through hole of general part all need be processed on drilling machine, on drilling machine, batch is when holing, and need use drill jig, and drill bushing is one of part on drill jig, the structure of drill bushing has varied, drill bushing, also known as drill jig sleeve or drill jig sleeve, in use, needs drill bushing to be arranged on the locating hole of bushing plate or clamp body, then cutter is through the pilot hole in the middle part of drill bushing, processes the workpiece be positioned at below bushing plate or clamp body.The effect of drill bushing, mainly be used for the axial location determining the sizing cutters such as drill bit, reamer, reamer, when the hole system that processing one group is parallel, and when the distance between this some holes has certain requirement, then utilize distributing position by the drill bushing of processing request to ensure the precision of above described holes heart distance.Sometimes use during drill bushing and there will be problem, particularly during boring, iron filings often can eject drill bushing come, and the light workpiece that causes is scrapped, and the heavy Drill Crack that causes even security incident occurs, and drill bushing blocks sometimes firm time, be difficult to take out from drill jig, lose time.
Utility model content:
Technical problem to be solved in the utility model is that overcoming existing technological deficiency provides a kind of anti-skidding fast brill drill bushing rational in infrastructure, easy to use.
Technical problem to be solved in the utility model adopts following technical scheme to realize:
Anti-skidding Quick-change drill bush, comprise drill bushing cap and targeting part, it is characterized in that: in described drill bushing, be provided with the pilot hole running through drill bushing cap and targeting part, described drill bushing cap is while be provided with cutting plane, described cutting plane is provided with projection, described targeting part is provided with some planes, extend vertically, the contact surface between targeting part and bushing plate is caused to reduce, when drill bushing is extracted from bushing plate, frictional force between drill bushing and bushing plate reduces, and described drill bushing cap is provided with the groove of multiple ring-type, increases the frictional force of hand and drill bushing cap.
Further, described projection thickness is less than drill bushing cap thickness, pushes down projection, plays fixing effect, even if there are iron filings to head on drill bushing like this, also drill bushing cannot be ejected bushing plate after the utility model is installed to bushing plate with a bolt.
The utility model use safety, and easily drill bushing is extracted from drill jig, time saving and energy saving, improve production efficiency.
Accompanying drawing illustrates:
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model plan structure schematic diagram;
Wherein: 1-drill bushing cap 2-targeting part 3-protruding 4-bolt 5-bushing plate
Detailed description of the invention:
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As shown in the figure, anti-skidding Quick-change drill bush, comprise drill bushing cap 1 and targeting part 2, it is characterized in that: in described drill bushing, be provided with the pilot hole running through drill bushing cap 1 and targeting part 2, described drill bushing cap 1 is while be provided with cutting plane, described cutting plane is provided with protruding 3, described targeting part 2 is provided with some planes, extend vertically, the contact surface between targeting part 2 and bushing plate 5 is caused to reduce, when drill bushing is extracted from bushing plate 5, frictional force between drill bushing and bushing plate 5 reduces, described drill bushing cap 1 is provided with the groove of multiple ring-type, increase the frictional force of hand and drill bushing cap 1.
Described projection 3 thickness is less than drill bushing cap 1 thickness, pushes down protruding 3, play fixing effect, even if there are iron filings to head on drill bushing like this, also drill bushing cannot be ejected bushing plate 5 after the utility model is installed to bushing plate 5 with a bolt 4.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
