Description
Technical field
The utility model relates to belong to component of machine processing technique field, gone for the reversed of various specifications hole in part
Burr processing, in particular to a kind of tool construction for the reversed deburring in groove aperture.
Background technique
There are the holes of different size in many cylindric machine components with groove, and vent surface can there are hairs after drilling
Traditional burr removing method can be used (such as: file, sand paper, bistrique polishing or edge iron craft unhairing in aperture forward direction burr in thorn
Thorn), removal that can be easy.And the reversed burr 01(for being limited aperture to be removed by recess space is shown in Fig. 1) just compared with
For difficulty.One is chemical deburrings for existing method: principle of electrochemical reaction is used, it is automatic to part made of metal material
Ground selectively completes deburring operation.It can be widely used for pneumatic, hydraulic, engineering machinery, oil nozzle oil pump, automobile, engine
Etc. the parts such as the pump housing, valve body, connecting rod, the plunger pintle nozzle match-ing parts of industries different metal materials deburring.Suitable for being difficult to
After the internal burr of removal, heat treatment and the part of finishing.There are also one is electrochemical deburrings: removing gold using electrolysis
Belong to a kind of electrochemical machining method of part burr, English abbreviation ECD.It is directed at burr seamed edge with the current-carrying part of tool cathode,
Other surfaces are covered with insulating layer, and electrolysis is made to concentrate on burr part.When processing, it is negative that tool cathode connects DC power supply
Pole, workpiece connect DC power anode.Pressure is that the low-voltage electrolysis liquid of 0.1~0.3 megapascal (generally uses sodium nitrate or chloric acid
Sodium water solution) it flows through between workpiece and cathode.After connecting DC power supply, burr just generates anodic solution and is removed, quilt
Electrolyte is taken away.Electrolyte has certain corrosivity, should be through over cleaning and antirust treatment after workpiece deburring.Electrochemical deburring is applicable in
The burr of concealment part cross bore or complex shape part in removal part, high production efficiency, deburring time generally only need
Several seconds to tens seconds.This method is usually used in deburrings and the wedge angles such as gear, spline, connecting rod, valve body and crankshaft oilway aperture
Rounding etc..The disadvantage is that surface can lose original gloss also by electrolysis near part burr, or even influence size essence
Degree.
Therefore how to seek a kind of high efficiency, the removal of high quality is with the tool of the reversed burr in slot parts aperture, always
It is the target that industry is pursued.
Utility model content
Technical problem to be solved in the utility model is the tool for devising a kind of reversed deburring, and removal drilling adds
The burr reversed in aperture caused by after work guarantees product quality, uses simple and convenient, does not need technical treatment, saves
About cost and environmental protection.
The utility model is solved the above problems using following technical scheme.A kind of work for the reversed deburring in groove aperture
Tool, including knife bar and blade, the lower end of the knife bar are provided with notch, and the blade is installed in notch by screw, and knife
The cutting edge of piece is upward.
The utility model solves the problems, such as the reversed deburring in element groove aperture, and high-efficient, aperture is reversely gone
Burr is high-quality, can be used not only for the reversed deburring in part aperture, and can be used for other part apertures with groove structure
The features such as reversed deburring has tool adaptable, and structure is simple, processes and is easy to assembly is promoted in field of machining
Value is high.
Detailed description of the invention
Fig. 1 is the schematic diagram of the reversed spur location in element groove aperture；
Fig. 2 is the schematic perspective view of the utility model；
Fig. 3 is the schematic perspective view of blade 2 in the utility model.
Specific embodiment
Below in conjunction with drawings and examples, the utility model is described in further detail.Referring to Fig. 1 to Fig. 3, one kind is for recessed
The tool of the reversed deburring of slot mouth, including knife bar 1 and blade 2, the lower end of knife bar 1 are provided with notch 11, and blade 2 passes through screw
3 are installed in notch 11, and the cutting edge 21 of blade 2 is upward.
Knife bar 1 in the utility model is manufactured using quality carbon tool steel, has intensity higher, toughness is preferable.Knife bar 1
Diameter can carry out matching production according to the aperture of different size.One is cut out using line cutting technology in an end of knife bar 1
The locating notch 11 of a accurate installation blade 2, is machined with a fastening thread hole, this threaded hole at the middle part of locating notch 11
Central axes be mutually perpendicular to notch 11.Blade 2 uses high-speed tool steel making, hardness with higher and preferable machinability
Can, the cutting edge of blade 2 is process with CNC Cutter Grinding Machine Tool, can form series with the matching of knife bar 1 by changing 2 parameter of blade
Tool, for removing the reversed burr 01 with different size aperture in slot parts.
When the utility model is used, directly tool reversely can be inserted along aperture when recess space is greater than the tool total height
Enter, then by knife bar 1 and slewing clamping, start slewing, burr can be removed under the shear action of blade 2.When
When recess space is less than 1 total length of knife bar, it first is inserted into knife bar 1 along aperture forward direction, is then combined knife bar 1 and blade 2, then
Knife bar 1 and slewing are subjected to clamping, reversed burr 01 can be removed under the shear action of blade 1 by starting slewing.
