Description
Technical field
The utility model relates to gear machining technology fields, more particularly to a kind of stepped gear wheel grinding attachment.
Background technique
Stepped gear wheel end face and outer circle, since structure is special, stepped gear wheel end is unable to complete using common lathe
The grinding operation of face and outer circle.
Utility model content
The purpose of this utility model is to be directed to technological deficiency existing in the prior art, and provide a kind of stepped gear wheel grinding
Device.
It is for technical solution used by realization the purpose of this utility model:
A kind of stepped gear wheel grinding attachment, including oblique lathe bed digital control lathe, in the inclined of the oblique lathe bed digital control lathe
It is fixed on moveable workbench there are two axis with the axis of workbench in 30 degree of bearing blocks intersected, two bearing blocks
On electro spindle is installed, the electro spindle intersects with workbench in 30 degree, is equipped on the electro spindle and is ground stepped gear wheel
Grinding wheel.
Dresser is installed on the main shaft of the oblique lathe bed digital control lathe.
The grinding working face of the grinding wheel is the inclined-plane of taper, can be protected when with the machined surface of ground stepped gear wheel
Hold line contact grinding.
Compared with prior art, the utility model has the beneficial effects that
The utility model on oblique lathe bed digital control lathe by being equipped with workbench in 30 degree of inclined electro spindles, electro spindle
On the grinding wheel of grinding stepped gear wheel is installed, can effectively realize and grinding is carried out to the end face of stepped gear wheel and outer circle,
Machining accuracy is high, and saves grinding wheel, and electro spindle can be protected not damaged.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of processed stepped gear wheel；
Fig. 2 is the structural schematic diagram of stepped gear wheel grinding attachment；
Fig. 3 is the partial enlargement diagram of main shaft part.
Specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that this place
The specific embodiment of description is only used to explain the utility model, is not used to limit the utility model.
As Figure 2-3, the stepped gear wheel grinding attachment of the utility model, including oblique lathe bed digital control lathe 300, it is described
Oblique lathe bed digital control lathe 300 includes workbench portion 200 and main shaft part 100, in the workbench portion of the oblique lathe bed digital control lathe
It there are two axis and the axis of workbench is in 30 degree of bearing blocks 50 intersected on 200 inclined moveable workbench 80, two
Electro spindle 60 is installed, the electro spindle intersects with the axis of workbench 80 in 30 degree, the electro spindle on a bearing block
The grinding wheel 70 of grinding stepped gear wheel 30 is installed on 60.
Wherein, the workbench is obliquely installed, can in an inclined state along axially and radially guide rail into
Row is mobile to carry out grinding to stepped gear wheel 30 fixed on main shaft 10 to realize.
It needs it is required that in the utility model, the structure of the oblique lathe bed digital control lathe 300 is prior art knot
Its structure and working principle process is no longer described in detail in structure.
In addition, dresser 20 is installed on the main shaft 10 of the main shaft part 100 of the oblique lathe bed digital control lathe, it is main
Processed stepped gear wheel 30 is equipped with by tooling 40 on axis 10, two end faces 301 of the stepped gear wheel 30 and outer circle are sand
Take turns 70 machined surfaces.
Wherein, the grinding wheel grinding working face be taper inclined-plane, in this way when with ground stepped gear wheel 30
One machined surface is able to maintain corresponding line contact, and carries out grinding.
In the utility model, by allowing electro spindle and workbench at 30 jiaos, have the effect that
1. protecting the bearing in electro spindle: when electro spindle does not remove angle, after grinding wheel and feature contacts, the bearing in electro spindle
What is be subject to is axial force entirely, is easy to damage bearing in this way；After removing one 30 degree of angle, bearing in electro spindle by
Power, some is assigned to radially, in this way to protection bearing have very big benefit.
2. saving grinding wheel: when electro spindle does not remove angle, when leaning on the end face of roll flute wheel, the grinding wheel of 20mm thickness will soon be by
It is finished；After removing one 30 degree of angle, it will be seen that either grinding the outer circle of part from diagram, or by mill
The end face of part, the saving of grinding wheel are apparent.
3. it is high to process element precision: when electro spindle does not remove angle, when leaning on the end face of roll flute wheel, being between grinding wheel and gear
Contact of the face with face, in this way, the rest and reorganization requirement to grinding wheel is just relatively high, this is more troublesome thing.Moreover, between face and face
Contact, the threshing of grinding wheel can all influence the precision of part.
After removing one 30 degree of angle, at the end face by grinding part, grinding wheel left side connects with part right side
Touching is that straight line [can only be one when contacting with part end face as soon as because being used to the grinding wheel by grinding part end face is a taper
Straight line], in this way by grinding the part come, flatness is good, and roughness might as well.
It adequately rinses and cools down 4. part, grinding wheel can obtain cutting fluid.Just because of grinding wheel left side and part right side
Contact be straight line, cutting fluid can enter sufficiently between grinding wheel and part, thus can fully be rinsed and
It is cooling, to can also improve the machining accuracy of part.
The above is only the preferred embodiment of the utility model, it is noted that for the general of the art
For logical technical staff, without departing from the principle of this utility model, several improvements and modifications can also be made, these change
It also should be regarded as the protection scope of the utility model into retouching.
