Abstract
The utility model discloses a kind of power steering pump stator to grind inner curve Self-centering device, including base, the base are hollow cylinder, and three adjusting screws are uniformly provided with base, only head screw, spring and spherical ball are mounted in each adjusting screw.The utility model is simple in construction, it is reasonable in design, in the case where scroll chuck can not be used to position, the plane compressing fixture carried using lathe, realize that cylindrical and plane positions jointly, inner curve and cylindrical confronting coaxial degree and symmetry when solving mill inner curve, and the perpendicularity problem with plane, meet the technical requirements of product.Registration, it is easy to operate, it is safe and efficient, man-hour is saved, reduces production cost.
Description
Technical field
Machining manufacturing technology field is the utility model is related to, specifically a kind of power steering pump stator mill inner curve is certainly
Centring means.
Background technology
Power assistance pump for steering is the important component of automobile, and the inner curve of power-assisted pump stator has certain axiality with cylindrical
With symmetry requirement, particularly there is very high perpendicularity requirement with plane, and it is cylindrical do not required with the perpendicularity of plane, institute
Just not account for cylindrical and plane perpendicularity when stator blank is manufactured.In order to ensure inner curve to the vertical of plane
Degree, when being ground inner curve, plane compression type clamping cannot can only be taken using scroll chuck come positioning and clamping, it is this
The defects of clamping is it is difficult to ensure that inner curve and cylindrical confronting coaxial degree and symmetry.So general all can be on stator in advance
Process positioning hole, but some stators, basic just have positioning hole, complete outer circle and plane position, and give inner curve processing
Bring certain difficulty.
Utility model content
The purpose of this utility model is to provide a kind of power steering pump stator mill inner curve Self-centering device, with solution
State the problem of being proposed in background technology.
To achieve the above object, the utility model provides following technical scheme：
A kind of power steering pump stator grinds inner curve Self-centering device, including base, and the base is hollow cylinder, bottom
Three adjusting screws are uniformly installed on seat, only head screw, spring and spherical ball are mounted in each adjusting screw.
As further program of the utility model：The radius of the base is 50mm, the hollow space of chassis interior
Radius is 27.5mm.
As the utility model further scheme：The adjusting screw is M12 screws, and only head screw is M8 screws.
Compared with prior art, the beneficial effects of the utility model are：The utility model is simple in construction, reasonable in design,
It can not use in the case that scroll chuck positions, the plane compressing fixture that is carried using lathe, realize that cylindrical and plane is jointly fixed
Position, inner curve and cylindrical confronting coaxial degree and symmetry when solving mill inner curve, and the perpendicularity problem with plane, it is full
The technical requirements of sufficient product.Registration, it is easy to operate, it is safe and efficient, man-hour is saved, reduces production cost.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：1- bases, 2- adjusting screws, 3- spherical balls, 4- springs, 5- stop head screw.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Referring to Fig. 1, a kind of power steering pump stator grinds inner curve Self-centering device, including base 1, the base 1 are
Hollow cylinder, three adjusting screws 2 are uniformly installed on base 1, only head screw 5, bullet are mounted in each adjusting screw 2
Spring 4 and spherical ball 3.
Further, the radius of base 1 described in the utility model is 50mm, and the radius of the hollow space inside base 1 is
27.5mm。
Further adjusting screw 2 described in the utility model is M12 screws, and only head screw 5 is M8 screws.
Power steering pump stator mill inner curve Self-centering device described in the utility model is mounted in the plane pressure that lathe carries
On chuck tool, according to the size of the stator outer diameter to be processed, three adjustment screws are adjusted to appropriate position, ensure three
Three summits of adjustment screw head spherical ball, are on a same circumference concentric with fixture inner circle, three substantially
The outside diameter circle of summit composition is smaller 0.5~1mm than stator outside diameter to be processed, and stator hand pressure to be processed is entered centering
In device, the spring 4 behind three spherical balls 3 and ball on centring means understands being pressed into for very convenient stator, and relies on bullet
The tension force automatic capturing center of spring 4 and compression are cylindrical.Completion of processing, just easily workpiece can be taken out with hand.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, it can realize that this practicality is new in other specific forms
Type.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and is nonrestrictive, this practicality is new
The scope of type limits by appended claims rather than described above, it is intended that the equivalency fallen in claim is contained
All changes in justice and scope are included in the utility model.Any reference in claim should not be considered as limitation
Involved claim.
Moreover, it will be appreciated that although the present specification is described in terms of embodiments, not each embodiment is only wrapped
Containing an independent technical scheme, this narrating mode of specification is only that those skilled in the art should for clarity
Using specification as an entirety, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art
It is appreciated that other embodiment.
