Description
Technical field
This utility model is related to impeller unit, belongs to clamping unshrouded impeller technical field.
Background technology
Unshrouded impeller applies to centrifugal air blast group, because its precision prescribed is high, need to clamp processing using special frock.Should
Device can ensure Impeller Machining precision, while facilitating impeller to clamp, check.
In the fabrication process, due to being affected by material, manufacturing process and assembling, there is initial unbalance, in impeller.Band
The impeller for having excessive amount of unbalance can produce vibration in high speed rotational operation, bring noise, shorten life of product, even bring
It is dangerous, it is therefore necessary to which that dynamic balance calibration process is carried out to impeller.During dynamic balance calibration process, typically using fixture by impeller
Hole clamps impeller.Impeller workpiece is put into by hand equipment by manual correction dynamic balancing machine by operative employee, and is mechanically clamped, its
Cost is relatively low, but production efficiency is low, and balance quality is not also high, it is impossible to meet the needs of efficiently production.Need accurate measurement
Go out the initial unbalance, of impeller workpiece.The precision of its measurement is largely determined by the fixture of clamping impeller endoporus.Open type
Impeller applies to centrifugal air blast group, because its precision prescribed is high, need to clamp processing using special frock.Existing clamping apparatus
Have no idea to allow operator's accurate measurement, cause many measurement data to there is larger deviation.
Utility model content
Therefore, the purpose of this utility model is to overcome existing clamping apparatus in prior art to have no idea to allow operator
Accurate measurement, causes many measurement data to there is larger deviation.
To achieve these goals, this utility model is a kind of frock of clamping unshrouded impeller, including clamping plate, pressing plate and
Fastening bolt, clamping plate upper surface is provided with two steps, and first step is located at impeller endoporus lower section and touches with interior hole end surface patch, and second
Step is located at clamping plate both sides and first step and second step are located at same level, and pressing plate is installed on clamping edges of boards edge and presses
Plate is provided with bar hole, and fastening bolt can be moved on bar hole.
Using above-mentioned technical proposal, impeller is clamped by fixed impeller hub disk, can be by adjusting by hub disk thickness
Bar hole makes it process impeller after being completely fixed.Impeller Machining precision and measurement impeller depth can be ensured by this device, for
Hub disk thickness difference is suitable for, and can effectively fix impeller, and device is simple, improves Impeller Machining efficiency.First step and
Two steps are located at same level, convenient to use miking impeller bore depth.Impeller is fixed on by pressing plate and is clamped on plate.
In the case of cylindrical identical, disc thickness is different after impeller, and the bar hole that can pass through to adjust on pressing plate is adjusted.
Further, the pressing plate be four, be uniformly distributed setting with it is on clamping plate and corresponding with the Leaf positional distribution of impeller,
The hub disk of impeller can preferably be fixed so as to preferably fix impeller.
Further, the pressing plate is wedge structure near one end of impeller, and clamping is more stable.
Description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structure top view of utility model.
Specific embodiment
Below by way of the drawings and specific embodiments, the utility model is described in further detail.
As illustrated, the present embodiment provides a kind of frock of clamping unshrouded impeller, including clamping plate, pressing plate and fastening spiral shell
Bolt, clamping plate upper surface is provided with two steps, and first step is located at impeller endoporus lower section and touches with interior hole end surface patch, second step position
In clamping plate both sides and first step and second step are located at same level, pressing plate be installed on clamping edges of boards along and pressing plate on set
There is bar hole, fastening bolt can be moved on bar hole.The pressing plate is four, is uniformly distributed on setting and clamping plate and and leaf
The Leaf positional distribution of wheel is corresponding.The pressing plate is wedge structure near one end of impeller.
During work, impeller is clamped by fixed impeller hub disk, it can be made by adjusting bar hole by hub disk thickness
Impeller is processed after being completely fixed.Impeller Machining precision and measurement impeller depth can be ensured by this device, it is thick for hub disk
Degree difference is suitable for, and can effectively fix impeller, and device is simple, improves Impeller Machining efficiency.First step and second step are located at
Same level, it is convenient to use miking impeller bore depth.Impeller is fixed on by pressing plate and is clamped on plate.Cylindrical identical
In the case of, disc thickness is different after impeller, and the bar hole that can pass through to adjust on pressing plate is adjusted.The pressing plate is four, uniform point
Cloth arrange with it is on clamping plate and corresponding with the Leaf positional distribution of impeller, can preferably fix the hub disk of impeller so as to preferably consolidate
Determine impeller.The pressing plate is wedge structure near one end of impeller, and clamping is more stable.
Obviously, above-described embodiment is only intended to clearly illustrate example, and not to the restriction of embodiment.For
For those of ordinary skill in the art, the change or change of other multi-forms can also be made on the basis of the above description
It is dynamic.There is no need to be exhaustive to all of embodiment.And the obvious change thus extended out or change
Among the dynamic protection domain created still in this utility model.
