Abstract
The utility model discloses a kind of shaving tool for being used to process concave circular arc quenching face, it includes blade, hold down assembly, cutter head and knife bar, the blade is connected by holding down assembly with cutter head, cutter head and the knife bar connection and formation angle a between the center line of the cutter head and the center line of knife bar, the utility model is by the way that the structure of cutter is improved, set and angle a is formed between the center line of cutter head and the center line of knife bar, so that cutter to raceway quenching face when being shaped as the work pieces process of concave circular arc, prevent quenching face bottom interference of the cutter to raceway, ensure smoothly completing for processing.
Description
Technical field
It the utility model is related to part tool technical field, and in particular to one kind is quenched for processing concave circular arc
The shaving tool in fiery face.
Background technology
The raceway face of existing workpiece (such as wind electricity change paddle yaw) is quenching face, and its hardness is 55-62HRC, general
Logical hard alloy cutter can not complete finishing processing after raceway quenching, and the structure of traditional wind electricity change paddle yaw connects for 4 points
Ball bearing is touched, its raceway is made up of quadrant, and use is processed without drift angle cutter to it in industry at present, but new
The structure of wind electricity change paddle yaw be two-point contact ball bearing, workpiece 6 in the shape such as Fig. 2 in the quenching face of its raceway face
Shown, this is shaped as concave circular arc, and the specially quenching face of workpiece raceway is made up of concave surface arc sections 61 and lug boss 62, this
Sample using current no drift angle cutter to the quenching face of such a shape when being processed, when needs quench without drift angle tool sharpening
During the bottom position of face, lug boss 62 will produce interference to the cutter, so that the cutter can not be carried out to the bottom for quenching face
Finishing processing.
Utility model content
The utility model, which overcomes in the prior art, to be present using the quenching face without drift angle cutter to concave circular arc raceway
When being processed, the lug boss for quenching the bottom in face can be to interfering, so as to realize to quenching face without drift angle cutter
The deficiency of bottom processing, there is provided it is a kind of when to the processing of quenching face bottom, interference will not be produced to the lug boss for quenching face bottom
Be used for process concave circular arc quenching face shaving tool.
To achieve the above object, the utility model uses following technical scheme：
A kind of shaving tool for being used to process concave circular arc quenching face, it includes blade, held down assembly, cutter head and knife
Bar, the blade are connected by holding down assembly with cutter head, and the cutter head is connected with knife bar and the center line and knife bar of the cutter head
Center line between form angle a.
Further technical scheme is that described hold down assembly passes through pressure including blade pressing block, the blade pressing block
Tight screw is fixedly mounted on cutter head and by blade pressing.
Further technical scheme is that the blade is shaped as circle.
Further technical scheme is that the blade is made of cubic boron nitride.
Compared with prior art, the beneficial effects of the utility model are：
The utility model by the way that the structure of cutter is improved, that is, set cutter head center line and knife bar center line it
Between formed angle a so that cutter to raceway quenching face be shaped as the work pieces process of concave circular arc when, prevent cutter to rolling
The quenching face bottom interference in road, ensure smoothly completing for processing.
Brief description of the drawings
Fig. 1 is that a kind of structure for being used to process the shaving tool that concave circular arc quenches face of embodiment of the utility model is shown
It is intended to.
Fig. 2 is the utility model use state diagram.
As illustrated, wherein corresponding reference is entitled：
1 blade, 2 blade pressing blocks, 3 cutter heads, 4 knife bars, 5 housing screws, 6 workpiece, 61 concave surface arc sections, 62 lug bosses.
Embodiment
The utility model is further elaborated below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of shaving tool for being used to process concave circular arc quenching face, it includes blade 1, compression group
Part, cutter head 3 and knife bar 4, the blade 1 are connected by holding down assembly with cutter head 3, and the cutter head 3 is connected with knife bar 4 and should
Formation angle a, described to hold down assembly including blade pressing block 2, the knife between the center line of cutter head 3 and the center line of knife bar 4
Piece compact heap 2 is fixedly mounted on cutter head 3 by housing screw 5 and compresses blade 1.
It is connected in the present embodiment by setting cutter head 3 with knife bar 4 and the center line of the center line of the cutter head 3 and knife bar 4
Between formed angle a so that when cutter is processed in the quenching face to concave circular arc raceway, cutter head 3 and knife bar 4 will not
Contacted with the lug boss 62 for quenching face, so as to ensure the shaping of the quenching face bottom processing to raceway.
In order that blade 1 meets the turning requirement that face is quenched to the raceway of workpiece 6, the preferable technical scheme of the present embodiment
For the blade 1 is shaped as circle, and the blade 1 is made of cubic boron nitride, by the shape of blade 1 in the present embodiment
It is set as circle, so that blade 1 preferably can be bonded in turning process with the raceway quenching face of workpiece 6, then passes through
Blade 1 is made from cubic boron nitride material, so that the hardness requirement in the raceway for the meeting workpiece 6 quenching face of blade 1.
Operation principle of the present utility model is as follows：
As shown in Fig. 2 the raceway of workpiece 6 (such as workpiece 6 is wind electricity change paddle yaw) quenches face by concave surface arc sections
61 and lug boss 62 form, i.e., by concave surface arc sections 61 and lug boss 62 make raceway quench face shape be in concave circular arc,
It is specific as follows, it is necessary to quench the setting of the shape progress parameter in face according to the raceway of workpiece 6 first during cutter is made,
Cutter head 3 is shaped to triangle, and the length of cutter head 3 is identical with the radius length of concave surface arc sections 61, the center line of cutter head 3
The size that angle a is formed between the center line of knife bar 4 is set according to the size of lug boss 62, by using above-mentioned parameter
The parameters of cutter are set, so as to the phenomenon for effectively preventing cutter and workpiece from interfering, then using cutter pair
The quenching face of workpiece 6 carries out finishing processing, because the material selection cubic boron nitride of blade 1 is made, it is possible to effective hard
Spend and be processed for 55-62HRC quenching face, when needing to be processed the bottom for quenching face, due to setting in cutter head 3
Angle a is formed between the center line of heart line and knife bar 4, so this is when blade 1 is moved to quenching face bottom position, cutter head 3
And knife bar 4 is all without knocking lug boss 62 over, so as to the phenomenon of interference effectively prevented, smoothly complete process.
Essence of the present utility model is described in detail above embodiment, but can not be to of the present utility model
Protection domain is limited, it should be apparent that, under enlightenment of the present utility model, those of ordinary skill in the art can be with
Carry out many improvement and modification, it should be noted that these are improved and modification all falls in claim of the present utility model protection
Within the scope of.
