Abstract
This utility model relates to process tool technical field, a kind of straight tool of end milling cutter changing cutting angle.A kind of straight tool of end milling cutter changing cutting angle, including broach shell and knife bar, knife bar is contained in broach shell, the end head of knife bar one end is positioned at outside broach shell, broach shell one side be respectively arranged at the two ends with a bolt hole, knife bar is locked with broach shell by the fastening bolt in bolt hole and gland, the end head of knife bar one end has an oblique cambered surface, the bottom of this oblique cambered surface connects blade, blade be provided above pressing plate, pressing plate is secured by bolts in the end head of knife bar one end.Unclamp gland, knife bar can be made to rotate in broach shell, thus change the anterior angle of whole billmpse tool and the angle of relief angle；The forward thrust compressing the cambered surface of retreading that pressured plate produces when pressing down of blade and pressing plate go forward the downforce of lower plane and clamping blade, sound construction, good stability；The angle of whole billmpse tool tool cutting edge angle can be changed around bearing pin rotating blade position.
Description
Technical field
This utility model relates to process tool technical field, outside a kind of machine folder changing cutting angle
Circular tool.
Background technology
For a long time, process tool is widely used in field of machining.Traditional billmpse tool mostly is one
Body formula structure, i.e. point of a knife and handle of a knife are formed in one, and when workpiece hardness is higher, lathe tool entirety is required for choosing
Take intensity higher material, such as wolfram steel etc., lathe tool only working portion and absorption surface, and the shank portion of lathe tool
Not with absorption surface, the waste of material will certainly be caused, cause production cost significantly to increase, and due to lathe tool
Bulk strength is higher, wastes time and energy during manufacture, inefficient.
In order to cost-effective, lathe tool being processed into split-type structural, common billmpse tool includes cutter hub, cutter
Sheet and for fixed structure that blade is fixed in the insert groove of cutter hub.At present, on sale on existing market
Billmpse tool has two kinds of models: a kind of is that the middle part of blade has through hole, by screw, blade is fixed on cutter
In film trap；A kind of is that the middle part of blade does not sets through hole, and this blade then and is consolidated blade pressing by compressing member
It is scheduled in insert groove.Blade is only fixed by this split type billmpse tool by a kind of mode, blade
Easily loosen man-hour adding, there is machining accuracy low；Adding man-hour, compressing member is susceptible to swing, and causes
Blade loosens, and equally exists machining accuracy low.
Utility model content
The technical problems to be solved in the utility model is: based on the problems referred to above, it is provided that a kind of sound construction, steady
The straight tool of end milling cutter of qualitative good changed cutting angle.
This utility model solves its technical problem and be the technical scheme is that a kind of cutting angle that changes
Straight tool of end milling cutter, including broach shell and knife bar, described knife bar is contained in broach shell, the position, termination of knife bar one end
Outside broach shell, described broach shell one side be respectively arranged at the two ends with a bolt hole, knife bar is by the fastening in bolt hole
Bolt and gland are locked with broach shell, and the end head of knife bar one end has an oblique cambered surface, and the bottom of this oblique cambered surface is even
Being connected to blade, the inner side of described blade is fixed with edge bearing, blade be provided above pressing plate, pressing plate passes through spiral shell
Bolt is fixed on the end head of knife bar one end.
Further, described blade is fixed in the end head of knife bar one end by bearing pin.Around bearing pin rotating knife
Sheet position can change the angle of whole billmpse tool tool cutting edge angle.
Further, it is provided with spheric washer between described pressing plate and the nut of bolt.Spheric washer is set, makes
Fixing of pressing plate is more firm, stable.
The beneficial effects of the utility model are: 1. unclamp gland, knife bar can be made to rotate in broach shell, thus change
Become the anterior angle of whole billmpse tool and the angle of relief angle；2. what the pressured plate of compression of blade produced when pressing down retreads
The forward thrust of cambered surface and pressing plate go forward the downforce of lower plane and clamping blade, sound construction, good stability；
3. the angle of whole billmpse tool tool cutting edge angle can be changed around bearing pin rotating blade position.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation in Fig. 1 on B-B direction.
Fig. 3 is the structural representation in Fig. 1 on A-A direction.
In figure: 1. broach shell, 2. gland, 3. fastening bolt, 4. knife bar, 5. bearing pin, 6. edge bearing, 7. blade,
8. pressing plate, 9. bolt, 10. spheric washer, 41. end head, 42. oblique cambered surfaces.
Detailed description of the invention
Presently in connection with accompanying drawing, this utility model is described in further detail.These accompanying drawings are showing of simplification
Being intended to, basic structure of the present utility model is described the most in a schematic way, therefore it only shows and this utility model
Relevant composition.
As shown in Figures 1 to 3, a kind of straight tool of end milling cutter changing cutting angle, including broach shell 1 and knife bar
4, knife bar 4 is contained in broach shell 1, and the end head 41 of knife bar 4 one end is positioned at outside broach shell 1, broach shell 1 side
Face be respectively arranged at the two ends with a bolt hole, knife bar 4 is by the fastening bolt 3 in bolt hole and gland 2 and broach shell 1
Locking, the end head 41 of knife bar 4 one end has an oblique cambered surface 42, and the bottom of this oblique cambered surface 42 connects cutter
Sheet 7, the inner side of blade 7 is fixed with edge bearing 6, blade 7 be provided above pressing plate 8, pressing plate 8 passes through spiral shell
Bolt 9 is fixed on the end head 41 of knife bar 4 one end, and specifically, blade 7 is fixed on knife bar 4 by bearing pin 5
In the end head 41 of one end, between the nut of pressing plate 8 and bolt 9, it is provided with spheric washer 10.
Unclamp gland 3, knife bar 4 can be made to rotate in broach shell 1, thus change whole billmpse tool anterior angle and
The angle of relief angle；The forward thrust of the cambered surface of retreading produced when compressing 8 times pressures of pressured plate of blade 7 and pressing plate 8
