Description
Technical field
The utility model relates to a kind of head-changeable reamers, belong to the technical field of reamer.
Background technique
Reamer be specifically applied to Precision Machining it is all kinds of have size, behavior tolerance, roughness requirements aperture knife tool.Tool
There are the features such as machining accuracy is high, high in machining efficiency, processing roughness is stablized up to Ra0.2-Ra1.6, processing dimension, existing reamer
In use for some time, there are wear phenomenon, reamer diameter itself becomes smaller, so that the hole after processing is not able to satisfy design and wants
It asks, more renews reamer higher cost, the period is longer, seriously affects production efficiency.
Summary of the invention
Purpose of utility model: above-mentioned in order to overcome the problems, such as, the utility model provides a kind of head-changeable reamer.
Process program: the utility model discloses a kind of head-changeable reamer, including knife bar, cutter head, connection bolt, the knife
Head is connect by connecting bolt with knife bar, and the cutter head is internally provided with interior cold hole, and interior cold hole is equipped with inside the knife bar, described
It connects and is equipped with threaded hole in bolt.
Further, the cutter head is internally provided with cold Kong Xiangtong in interior cold hole and knife bar inside.
Further, the knife bar is equipped with blade, and the blade is straight cutting edge and oblique cutting edge.
The utility model has the advantage that
1, by replacement reamer head, so that reamer cutting parts diameter meets design requirement, production cost, contracting are reduced
The short tool changing period improves production efficiency；It is provided with interior cold hole, provide cooling for cutter in high-speed cutting and assists chip removal.
2, have high reliablity, it is compact-sized, realize water-cooled cooling, tool sharpening speed is fast, tool change time is short, without pre-
Adjust, compensation, to knife, the advantages that adaptability is good.While there are extensive market prospects being machined into processing market.
Detailed description of the invention
A kind of Fig. 1: structural schematic diagram of head-changeable reamer of the present embodiment.
Fig. 2: the structural schematic diagram of the present embodiment knife bar.
In figure: knife bar 1, cutter head 2, connection bolt 3.
Specific embodiment
The utility model is further elaborated below in conjunction with attached drawing and by specific embodiment, it should be pointed out that: for this
For the common process personnel of technology field, without departing from the principle of this utility model, to the various of the utility model
The modification of equivalent form falls within the application range as defined in the appended claims.
Embodiment 1:
It is described if Fig. 1 institute the utility model discloses a kind of head-changeable reamer, including knife bar 1, cutter head 2, connection bolt 3
Cutter head 2 is connect by connecting bolt 3 with knife bar 1, and the cutter head 2 is internally provided with interior cold hole, is equipped with inside the knife bar 1 interior cold
Hole, the interior connection for realizing cutter head 2 and knife bar 1 by threaded hole equipped with threaded hole of connection bolt 3, passes through taper fit, protects
The precision of reamer is demonstrate,proved, the knife bar 1 is equipped with blade, and the blade is straight cutting edge and oblique cutting edge, and straight cutting edge knife bar is in
Heart line direction is parallel, and oblique cutting edge center forms an angle with knife bar direction.
The utility model has the advantage that
1, by replacement reamer head, so that reamer cutting parts diameter meets design requirement, production cost, contracting are reduced
The short tool changing period improves production efficiency；It is provided with interior cold hole, provide cooling for cutter in high-speed cutting and assists chip removal.
2, have high reliablity, it is compact-sized, realize water-cooled cooling, tool sharpening speed is fast, tool change time is short, without pre-
Adjust, compensation, to knife, the advantages that adaptability is good.While there are extensive market prospects being machined into processing market.
