Description
Technical field
The utility model relates to Impeller Machining technical fields, adjust more particularly to a kind of impeller end-face coupling concentricity
Device.
Background technique
Currently, centrifugal air compressor group develops towards smaller volume, high parameter and high-revolving direction is occupied.Rotor
Main shaft and impeller couple the form for often using end-tooth pair, such as Fig. 1.It is with moment properties height, self-centering, again
The advantages that answering precision height, being convenient to mount and dismount.Grinding is carried out with molding mill to end-tooth, has reached higher machining accuracy and tooth
Face finish has become universal fine-processing technique.
In order to reach bigger pressure ratio, the actual size of impeller (such as Fig. 2) is increasing (reaching 1500mm), due to impeller without
Method is fixed on platen, and the material of impeller is generally stainless steel, when actual processing adjusts concentricity, it is easy to tap
Cause in the process deformable blade (variation of blade streamline), and then influences compression efficiency.So impeller especially large impeller end-tooth
The correction of workpiece and it is machined with very big difficulty.
Utility model content
For above situation, for the defect for overcoming the prior art, the purpose of the utility model is just to provide a kind of impeller end
The problem of face tooth processes concentricity adjusting device, the effective solution correction and processing difficulties of large impeller end-tooth workpiece.
Its technical solution solved the problems, such as is a kind of impeller end-face coupling concentricity adjusting device, including pedestal, pedestal
It is equipped with groove, accommodating tool in groove, groove internal diameter is greater than tooling outer diameter, and groove is evenly distributed in multiple adjustment bolts, adjusts
The inner end of whole bolt resists tooling, and stroke of the adjustment bolt in groove adjusts the concentricity of tooling and pedestal, tooling top
Equipped with seam allowance, impeller cooperates through seam allowance and tool locating.
The utility model structure is simple, easy to use, the concentricity of impeller and lathe can be quickly adjusted, thus more preferably
Processing impeller end-tooth.

Specific embodiment
Specific embodiment of the present utility model is described in further detail below in conjunction with attached drawing 1-7.
By Fig. 1 to Fig. 7 it is found that a kind of 6 end-face coupling concentricity adjusting device of impeller, including pedestal 1, set on pedestal 1
Fluted 2, accommodating tool 3 in groove 2,2 internal diameter of groove is greater than 3 outer diameter of tooling, and groove 2 is evenly distributed in multiple adjustment bolts 4,
The inner end of adjustment bolt 4 resists tooling 3, and stroke of the adjustment bolt 4 in groove 2 adjusts the concentricity of tooling 3 and pedestal 1,
Seam allowance 5 is equipped with above tooling 3, impeller 6 is through seam allowance 5 and 3 location fit of tooling.
2 lower circumference of groove is evenly equipped with multiple steel balls 7, and tooling 3 is placed on steel ball 7.
The impeller 6 is fixedly connected through interior six square bolt 8 with tooling 3.
4 inner end of adjustment bolt is equipped with brass head 9.
When the utility model is used,
Tooling 3 and impeller 6 are positioned by 5 small―gap suture of seam allowance, and are fixed on impeller 6 and tooling 3 with interior six square bolt 8
Together, guarantee the concentricity of impeller 6 and tooling 3 in this way.
Pedestal 1 is fixed on platen, the impeller 6 being fixed together and tooling 3 are then lifted into pedestal 1
On, it enters tooling 3 in the groove 2 of pedestal 1, concentricity of the tooling 3 on pedestal 1 is then adjusted using adjustment bolt 4,
Adjust the concentricity between impeller 6 and lathe.
The end that adjustment bolt 4 resists tooling 3 is equipped with brass head 9, and brass is lower than the hardness of tooling 3, can play resistance to
The effect of mill, and tooling 3 will not be weighed wounded.
It is equipped with the steel ball 7 of multiple supporting tools 3 in 2 bottom of groove, when adjusting the concentricity of impeller 6, steel ball 7 can subtract
Frictional force between small footprint 1 and tooling 3 avoids damage tooling 3 or pedestal 1.
The utility model compared with the existing technology, increases the tooling of adjustment impeller concentricity, can be realized quick adjustment
The purpose of impeller concentricity improves the efficiency of processing impeller end-tooth.
