Description
Technical field
The utility model belongs to cutting-tool engineering field, more particularly to a kind of special machined burrs cutter.
Background technology
The inner flow passage edge of turbocharger housing is the border of circular arc and blank hypotenuse, is irregular shape（Such as Fig. 1 institutes
Show）, this position is not allow for any burr at A in figure, and flange, curved surface is not allow for any flaw.But product is because needing
The space length at deburring position is too small, and conventional knife cannot pass through, and goes flash removed easily to scratch curved surface by hand, causes product report
It is useless.
Utility model content
The utility model is intended to overcome the defect of prior art, there is provided a kind of special machined burrs cutter.
In order to solve the above-mentioned technical problem, the utility model provides following technical scheme：A kind of special machined burrs
Cutter, including broach shell, knife bar and blade, described knife bar one end are stretched into the broach shell, and coordinate with broach shell gap, the knife bar
Broach shell one end is stretched into for step structure, and first annular space is formed with broach shell inner chamber, the is provided with first annular space
One spring, the knife bar is realized moving up and down in the presence of the first spring；The other end of the knife bar is provided with shoulder hole, described
Blade penetrates the shoulder hole intermediate gap and coordinates, and the blade is distributed in vertical direction with knife bar, the shoulder hole and the knife
Piece is formed and second spring is set in the second annular space, the second annular space, and the blade is realized in the presence of second spring
Side-to-side movement.
Preferably, the knife bar stretches into the part of broach shell and is provided with cotter way, and just pin is provided with to cotter way position on the broach shell
During hole, inserts backing pin in pin hole, and backing pin stretches into the cotter way, when the knife bar moves up and down, backing pin plays spacing work
With.
Preferably, the tail end of the blade is provided with screw.
The utility model beneficial effect is：The utility model is controlled by using broach shell, knife bar, blade and dual spring, knife
Tool can be realized being changed according to product design and four direction floats up and down, disposably complete processing request.Avoid because
The product rejection that artificial removal's burr is caused.
Brief description of the drawings
Fig. 1 is the structural representation of turbocharger housing inner flow passage in the prior art；
Fig. 2 is the structural representation of the special machined burrs cutter of the utility model；
Fig. 3 is the special machined burrs cutter use state structural representation of the utility model；
In figure：1 broach shell, 2 knife bars, 3 blades, 4 first annular spaces, 5 first springs, 6 cotter ways, 7 backing pins, 8 second annulars
Space, 9 second springs, 10 screws.
Specific embodiment
The utility model is described further in conjunction with the accompanying drawings and embodiments.
As shown in Figure 2,3, a kind of special machined burrs cutter, including broach shell 1, knife bar 2 and blade 3, the one end of the knife bar 2
Stretch into the broach shell 1, and coordinate with the gap of broach shell 1, the knife bar 2 stretches into the one end of broach shell 1 for step structure, and and broach shell
1 inner chamber forms in first annular space, first annular space 4 and is provided with the first spring 5, and the knife bar 2 is in the first spring 5 and axle
Moved up and down to realization in the presence of the stress point of step structure；The other end of the knife bar 2 is provided with shoulder hole, the blade
3 penetrate the shoulder hole intermediate gap coordinates, and the blade 3 is distributed in vertical direction with knife bar 2, the shoulder hole and the blade
3 form the and annular space 8, the and second spring 9 is set in annular space 8, the blade 3 is in second spring 9 and cutter footpath
To realizing side-to-side movement in the presence of stress point.
Wherein, the knife bar 2 stretches into the part of broach shell 1 and is provided with cotter way 6, and just pin is provided with to the position of cotter way 6 on the broach shell 1
Nail, insertion backing pin 7 in pin hole, and backing pin 7 are stretched into the cotter way 6, and when the knife bar 2 moves up and down, backing pin 7 plays limit
The effect of position.
In addition, the tail end of the blade 3 is provided with screw 10, screw 10 promotes blade 3 to move to the right, the spiral shell of screw 10
Cap can extrude second spring 9, when blade 3 needs lateral movement to the left, then decontrol screw 10, and the elastic force of second spring 9 can be promoted
The lateral movement to the left of screw 10, so that the band lateral movement to the left of cutting blade 3.
Dedicated tool profile of the present utility model is small, applied widely, aperture the ￠ 35mm, more than groove width 4.5mm of product
Can use.By using more than a year, mark position burr is effectively removed, and using effect is good, has reached product
Deburring requirement.
In this description, the utility model is described with reference to its specific embodiment.But it is clear that still can be with
Various modifications and alterations are made without departing from spirit and scope of the present utility model.Therefore, specification and drawings are considered as
It is illustrative and not restrictive.
