Abstract
The utility model belongs to the field of drilling tools, and particularly relates to a burring cutter used for removing burrs on the inner wall of a hole and the edge of the hole. The burring cutter comprises a cutter handle, wherein the cutter handle is connected with a power device. The burring cutter is characterized in that one end of the cutter handle is connected with a burr cutting portion, the burr cutting portion comprises spiral cutting blades arranged on the surface of the burr cutting portion, a chip groove is formed between every two adjacent spiral cutting blades, and chamfers are arranged on the lower end face of the burr cutting portion. The burring cutter capable of removing the burrs on the edge of the hole and the inner wall of the hole can remove the burrs on the edge of the hole and the inner wall of the hole at a time, and is high in production efficiency.
Description
Technical field
The utility model belongs to the drilling cutters field, particularly a kind ofly carries out the burring knife that burr is removed for hole inwall and bore edges.
Background technology
Existing surface of the work all needs machining hole, drilling processing is generally adopted in the hole, the inwall in the hole that processes and surface are all and some workpiece having relatively high expectations to the quality of the inwall in the edge quality in these holes and hole, just need to carry out secondary operations to edge and the inwall in hole, the general drill bit that adopts carries out the quality that repeatedly drilling improves the hole, but processing has affected the size in hole and the circularity in hole like this, and there is certain impact in follow-up use.
Summary of the invention
The utility model is for the deficiencies in the prior art, designed a kind of burring knife that can remove the burr of bore edges and hole inwall, can disposable removal bore edges and the burr of inwall, have higher production efficiency.
The utility model is achieved through the following technical solutions:
Burring knife, it comprises handle of a knife, handle of a knife is connected with power set, it is characterized in that: an end of described handle of a knife is connected with the burr cutting portion, described burr cutting portion comprises the spiral cutting sword that is arranged on burr cutting portion surface, be provided with chip area between the adjacent spiral cutting sword, the lower surface of described burr cutting portion is provided with chamfering.
The top of described burr cutting portion radially is provided with trapezoidal annular groove along the burr cutting portion.
The utlity model has following advantage:
The utility model has designed a kind of dedicated tool of deburring, can once finish the removing to the burr of the edge in hole and inwall, has improved working (machining) efficiency, satisfies the needs that high speed machining is produced.
Description of drawings
By the detailed description below in conjunction with accompanying drawing, aforesaid purpose, the feature and advantage with other of the utility model will become apparent.Wherein:
Figure 1 shows that structural representation of the present utility model;
1 is chamfering among the figure, and 2 is chip area, and 3 are the spiral cutting sword, and 4 is trapezoidal annular groove, and 5 is handle of a knife.
The specific embodiment
Burring knife as shown in Figure 1, it comprises handle of a knife 5, handle of a knife 5 is connected with power set, it is characterized in that: an end of described handle of a knife 5 is connected with the burr cutting portion, described burr cutting portion comprises the spiral cutting sword 3 that is arranged on burr cutting portion surface, the spiral cutting sword is used for the burr of hole inwall is removed, be provided with chip area 2 between the adjacent spiral cutting sword 3, the chip area that arranges is used for the burr that cuts is got rid of timely, avoiding cutting the burr that gets off affects the quality of hole inwall again, the lower surface of described burr cutting portion is provided with chamfering 1, the chamfering that arranges is convenient on the one hand to the heart, also can be used on the other hand the burr of bore edges is gone out.
The top of described burr cutting portion radially is provided with trapezoidal annular groove 4 along the burr cutting portion.
The utlity model has following advantage:
The utility model has designed a kind of dedicated tool of deburring, can once finish the removing to the burr of the edge in hole and inwall, has improved working (machining) efficiency, satisfies the needs that high speed machining is produced.
