Abstract
The present invention relates to a kind of for processing the fixture of annular workpieces outer surface, it is characterized by comprising the round briquettings that positioning disk, the tensioner ring with notch and inner wall with taper and outer wall have taper, the taper of the circle briquetting match with tensioner ring inner wall taper, the processed tensioner ring inner ring set with described with notch and inner wall with cooperation outer wall after the tensioner ring of taper with the central area for being fastened on the positioning disk after conicity circular briquetting by fastener.In the present invention, as long as by positioning disk by clamp in the prior art, when using laser welding wearing layer, due to the taper fit of notch and round briquetting on tensioner ring, so that processed circular thin-wall workpiece inner wall uniform force, thus, after processing, processed annular workpieces are unlikely to deform, to guarantee the quality of product after laser overlaying welding wearing layer.
Description
Technical field
The present invention relates to a kind of fixture, especially a kind of annular workpieces appearance surface build-up welding fixture.
Background technique
Annular workpieces have the hardness, wear resistance, corrosion resistance of its outer surface very high as a kind of hard sealing element of rotation
Requirement, the raw material of these workpiece are typically all steel, thus, by steel vehicle be annular workpieces after, it is also necessary to by annular work
The outer surface of part carries out surface modification treatment.Common method uses supersonic cold gas spray or thermal spraying mode, both modes
There are many limitations.More commonly used technology is including manual build up welding, plasma automatic surfacing by the way of built-up welding now
With laser melting coating (built-up welding), and laser melting coating is a kind of advanced welding method used in recent years, with manual build up welding, plasma
The characteristics of automatic surfacing has energy conservation and environmental protection, and uniformity is good, and dilution rate is small, high degree of automation, i.e., be fixed on annular workpieces
On fixture, then laser irradiation workpiece surface forms molten bath, while powdered specific alloy material being sent in molten bath, thus
Wearing layer required for being formed.When annular workpieces are fixed on fixture, commonsense method, is to use scroll chuck from inside at present
Annular workpieces need to be processed to fix, the workpiece that rapidoprint volume is big in this way or wall thickness is thicker, the work after processing
Part deflection is little, and for thin-wall workpiece, heat when welding cannot be distributed since material heat capacity is small in time, cause to be added
The annular workpieces of work occur heat expansion phenomenon and loosen, and in order to guarantee going on smoothly for processing, need to rise in time in process
Tight scroll chuck, annular workpieces are deformed while cooling after processing is completed, especially at three-point mount, the degree of deformation
It is even more serious, thus, the annular workpieces after processing have not been circles, and in order to guarantee to have enough machining allowance, welding layer is needed
Enough thickness is wanted, post-production workload is very big, and be easy to cause waste product.
Summary of the invention
In view of the deficiencies of the prior art, the technical problem to be solved in the present invention is to provide a kind of fixtures to make circular thin-wall workpiece
It is indeformable to be also unlikely to deform especially bearing for generation heat expansion in weld deposit process.
For this purpose, the present invention adopts the following technical scheme that realize: one kind being used for the built-up welding of circular thin-wall outer surface of workpiece
Fixture, it is characterised in that including positioning disk, the tensioner ring with notch and inner wall with taper and outer wall have taper circle
Shape briquetting, the tensioner ring are matched with notch described in one, the taper of the circle briquetting with tensioner ring inner wall taper, institute
It states with notch and there is inner wall the tensioner ring of taper to be placed in the processed circular thin-wall workpiece, then the outer wall is had
Tapered circle briquetting be embedded in it is described with notch and inner wall have in the tensioner ring of taper after it is by fastener that round briquetting is tight
Gu on the positioning disk.
This structure of the invention, when annular workpieces expand with heat and contract with cold, the notch and its inner wall that have due to tensioner ring
Taper and outer wall have taper round briquetting cooperation after, on the one hand increase the thermal capacity of material, the temperature rise of material eases up,
Another aspect tensioner ring with certain elasticity under the action of outer wall has the round briquetting of taper, with annular work when heating
Part expansion guarantees that annular workpieces do not loosen, the periphery of its tensioner ring and inner wall of processed annular workpieces is comprehensive connects when cooling
Touching makes the uniform cooling meat of processed annular workpieces, thus, processed annular workpieces no matter heat expansion or when shrinkage
It is all highly uniform, annular shape is still maintained after guaranteeing annular workpieces processing, meanwhile, processed annular workpieces are realized quick
Handling clamp.
Several concentric circles graduation marks are provided on the positioning disk, fast and easy positioning improves efficiency.
Preferably the fastener is bolt, and the center of positioning disk has through-hole, and bolt passes through the through-hole.
Preferably positioning disc side is equipped with the short axle with positioning disk concentric, for linking with scroll chuck.
In conclusion being also unlikely to deform the beneficial effects of the present invention are: annular workpieces is made to generate heat expansion in process
Especially guarantee the circularity of its shape.
Detailed description of the invention
Fig. 1 is the structure chart of present clip；
Fig. 2 is the structure chart of positioning disk of the present invention；
Fig. 3 is structure chart when tensioner ring of the present invention is placed in positioning disk center with round briquetting；
Fig. 4 is the structure chart of tensioner ring.
Specific embodiment
As shown, this fixture for processing annular workpieces outer surface includes that positioning disk 5, band notch and inner wall have
The tensioner ring 2 and outer wall of taper have the round briquetting 3 of taper, and the tensioner ring 2 is with notch described in one, circle pressure
The taper of block 3 is matched with 2 inner wall taper of tensioner ring, is processed 1 inner ring of tensioner ring and is set after the round briquetting 3 of cooperation after tensioner ring 2
The central area of positioning disk 5 is fastened on by bolt 4.It wherein, when processed annular workpieces being fastened, is carried out by bolt
Fastening, there is through-hole at the center of positioning disk, bolt passes through the through-hole, as long as screwing bolts, with round briquetting internal pressure,
Just processed annular workpieces are fastened.Certainly, after annular workpieces are fastened on positioning disk, using folder in the prior art
Tool will position chuck clamping, can just work.
When generation is expanded with heat and contract with cold when processed annular workpieces 1 are processed and after processing, due to the work of the notch of tensioner ring 2
After matching with the round briquetting with taper, tensioner ring 2 and then expands with heat and contract with cold, so that the annular workpieces inner wall stress added is equal
It is even, thus, guarantee that the annular workpieces after being processed are indeformable, while realizing quick despatch, clamping.If being provided on positioning disk 5
Dry concentric circles graduation mark 8, as long as placing annular workpieces alignment graduation mark when processing, convenient processed annular workpieces are fast
Speed positioning is to improve processing efficiency.The side of positioning disk 5 is equipped with short axle 6 with positioning disk concentric, in the prior art fixture
As long as the outer ring that clamping bar clamps short axle 6 just will position chuck clamping.To realize that laser overlaying welding is processed.
