Description
Technical field
The present invention relates to the frock clamp of a kind of part shot peening, be specifically designed a kind of two ends size structure not phase
The frock clamp of the part shot peening of same aeronautical product ring-shaped work pieces.
Background technology
For bearing the aviation part of alternate stress, such as load part important on aircraft, electromotor, though it destroys
So have a various ways, but main and substantial amounts of be fatigue rupture.Improve part fatigue resistance one
Major way, is that part is carried out shot peening.Numerous parts in aero-engine is required for spraying
Ball intensive treatment.The aeronautical product ring-shaped work pieces differing two ends diameter or structure carries out both ends of the surface and inside and outside
Surface shot blasting strengthening processes, and needs to be fixed on shot blasting equipment ring-shaped work pieces by frock clamp.For fixing
The frock clamp of ring-shaped work pieces, method for designing known in the art is to use two groups of frock clamp schemes, a set of
Frock clamp is using the large end face of ring-shaped work pieces as the support locating surface of ring-shaped work pieces, and a set of frock clamp is with annular
The small end face of part is as the support locating surface of ring-shaped work pieces, and all uses whole inner headed face or periphery to annular
Part positions.The place that the Fixture designing method of prior art is substantially not enough is, needs the work used
Clamps quantity is many, and processing cost is high, and during shot peening, when an end face shot-peening of ring-shaped work pieces
After having processed, need to take off part and current frock clamp, could continue to add after again changing frock clamp
Work, causes working (machining) efficiency low, is unfavorable for producing in enormous quantities.In addition, due to use whole inner headed face or
Part is positioned by periphery, and part is bigger with the faying face of fixture, there is the dead angle that shot-peening can not arrive,
The surface of ring-shaped work pieces can not all obtain shot peening strengthening, and shot-peening stream pressure is high, and ball Flow Velocity is fast, therefore,
This installation way can cause occurring during shot-peening that pill enters into the faying face of part and fixture thus leads
Cause the phenomenon of scratch part.
Summary of the invention
Not enough for the frock clamp positioning the different ring-shaped work pieces of upper and lower side structure for prior art, the present invention
The frock clamp for aeronautical product ring-shaped work pieces shot peening provided, first problem to be solved is letter
Change the quantity reducing frock clamp, improve working (machining) efficiency；Second Problem to be solved is to eliminate ring-shaped work pieces
Surface shot blasting strengthening dead angle, it is to avoid occur during shot-peening that pill enters into the faying face of part and fixture and causes wiping
Hinder part.
For first problem to be solved by this invention, what the present invention provided sprays for aeronautical product ring-shaped work pieces
The frock clamp of ball processing, consists of: frock clamp body is collar plate shape structure, the fixture of collar plate shape structure
The annular support surface for supporting annular part end face it is designed with, on described annular support surface, annular on body
Outside supporting surface, inside annular support surface at three in two be on the circumference of respective same diameter design no less than three
The individual equally distributed alignment pin for positioning ring-shaped work pieces, described alignment pin is big with ring-shaped work pieces by pin body
Ring-shaped work pieces is positioned on annular support surface by end or the inner circle of small end or cylindrical cooperation.
For specific aeronautical product ring-shaped work pieces, what the present invention provided adds for aeronautical product ring-shaped work pieces shot-peening
The frock clamp of work, its constitute be designed with on the same diameter circumference of annular support surface three equally distributed
The alignment pin for positioning ring-shaped work pieces matched with ring-shaped work pieces small end inner circle, in the outside of annular support surface
Be designed with on same diameter circumference that three equally distributed end cylindricals big with ring-shaped work pieces match for positioning
The alignment pin of the big part of annular.
In the technique scheme of the present invention, described annular support surface pays the utmost attention to be designed as the ring of bulge-structure
Shape supporting surface.
For Second Problem to be solved by this invention, what the present invention provided sprays for aeronautical product ring-shaped work pieces
The frock clamp of ball processing, is provided with pill during preventing shot-peening on annular support surface and enters annular support surface
And scratch part end face packing ring, preferentially use rubber washer.Further scheme, is outside equipped with bullet at alignment pin
The overcoat of property material, the alignment pin end big with ring-shaped work pieces or the coordinating of small end that are provided with overcoat are tight fit.Outward
The preferential overcoat using quality of rubber materials of set.
In the technique scheme of the present invention, the middle part of described frock clamp body is preferably devised with alleviating fixture
The hole of this body weight.
In the technique scheme of the present invention, described chuck body is symmetrically arranged with a pair for moving frock
The handle of fixture.
The frock clamp for aeronautical product ring-shaped work pieces shot peening that the present invention provides, passes through prior art
The frock clamp of two sets the location big end of ring-shaped work pieces or small end respectively combines dexterously, presss from both sides with a set of frock
Tool can coordinate with the big end of ring-shaped work pieces or small end and positions part, it is achieved two ends are had different-diameter
Or the inside and outside disc of the ring-shaped work pieces of structure and upper and lower end face carry out shot peening, ring-shaped work pieces is being carried out
During shot-peening, only the two ends of ring-shaped work pieces need to be overturn, be not required to change frock clamp, can spray
Ball is processed, and not only decreases the quantity of frock clamp, reduces processing cost, also eliminates replacing frock simultaneously
The complicated procedures of fixture, substantially increases working (machining) efficiency.Additionally, in the frock clamp that the present invention provides, for
During preventing shot-peening, pill enters annular support surface and scratches part, is provided with especially on annular support surface
End washer；In order to avoid during shot-peening, pill enters the location of ring-shaped work pieces inner headed face or periphery and pin
Scratch part between face, outside alignment pin, be provided with rubber sleeve especially, and make the alignment pin of overcoat rubber sleeve with
The cooperation of the big end of ring-shaped work pieces or small end is tight fit.Due in only big with the ring-shaped work pieces end of alignment pin or small end
Disc or periphery coordinate location, and ring-shaped work pieces surface shot blasting strengthening does not has dead angle, and the surface of ring-shaped work pieces can
Obtain shot peening strengthening.
The frock clamp for aeronautical product ring-shaped work pieces shot peening that the present invention provides, positions with prior art
The frock clamp of aeronautical product ring-shaped work pieces shot peening is compared, sum up have following the most prominent useful
Technique effect:
1, decrease the quantity of frock clamp, reduce processing cost.
Need to change the tedious steps of fixture when 2, avoiding part turn-over shot-peening, improve working (machining) efficiency.
3, pill during shot-peening can be entirely prevented from and enter the situation of locating surface scuffing part.
4, Tool clamp structure is simple, can be as the reference during other like parts shot-blast processes.
