Abstract
Present invention seek to address that can not accurate judgement runner solder fillet relief grinding surplus the problem of, there is provided a kind of runner weld seam fillet relief grinding surplus detects model.Model includes being made up of the first model element, the second model element and a rivet to axle pivot the first model element and the second model element.The side of first model element and the second model element coincide with blade and runner part (crown or lower ring) respectively to be affixed, gap by measuring arc section and solder fillet is assured that runner weld seam fillet relief grinding surplus, it is excessive or too small and done over again to avoid relief grinding surplus, there is provided one group of model can repeat to detect the runner of different size, the purpose of cost efficiency is reached, the present invention has the characteristics that making is simple, easy to use, versatile, easy to spread.
Description
Technical field
The present invention relates to a kind of runner weld seam fillet relief grinding surplus to detect model.
Background technology
Weld seam fillet is important performance assessment criteria in hydraulic turbine cast-weld construction manufacturing of runner technical conditions, runner after welding equipment,
Weld in blade and runner part (crown or lower ring) connecting position and to form knuckle, then by weld seam fillet relief grinding into design
It is required that R values, and surface roughness requirements are not more than Ra3.2.Conventional runner is after welding equipment, with the emery wheel of correlation radius size
Or the mode of naked eyes measuring and calculating determines whether weld seam fillet has enough relief grinding surpluses, this test mode is very rough, it is impossible to accurate
The size of true detection relief grinding surplus, cause follow-up relief grinding surplus amount excessive or portion without relief grinding surplus, it is necessary to enter again
Row repair welding.
Therefore, it is necessary to the defects of existing for prior art, research and development one kind is simple and easy, versatile, cost is cheap,
Runner weld seam fillet relief grinding surplus detection model easy to spread.
The content of the invention
Present invention aim to address can not accurate judgement runner weld seam fillet relief grinding surplus the problem of, there is provided Yi Zhongzhuan
Take turns weld seam fillet relief grinding surplus detection model.The used to achieve the above object technical scheme of the present invention is：By the first model
Element (10), the second model element (12) and axle pivot rivet (11) composition, the first model element (10) are justified by the first excessively detection
Arc (1), positioning through hole (2), first side (3), second side (4), first residue gap (5), the second surplus gap (6),
One knuckle (7), the second knuckle (8) and hand-held through hole (9) composition, the first model element (10) and the second model member
The single-piece size and dimension of part (12) is identical, and the first model element (10) and the second model element (12) pass through axle pivot rivet
(11) fix and can freely rotate through the mode of positioning through hole (2), detection blade (13) is appointed with what runner part (14) was formed
Runner weld seam (15) radius of corner R of what angle.
Described first side (3) and second side (4) are two parallel lines, with runner weld seam (15) fillet to be detected
R is tangent, and first side (3) and second side (4) leave first residue gap (5) and more than second with detection circular arc (1) junction
Measure gap (6).
In detection process, first side (3) and the blade (13) of the first model element (10) or the second model element are kissed
Conjunction is affixed, and the second side (4) of the second model element (12) or the first model element is coincide with runner part (14) to be affixed, and first
Excessively nominal sizes of detection circular arc (1) the radius r equal to runner weld seam (15) fillet R subtracts reserved maximum relief grinding surplus, i.e.,
Width dimensions corresponding to first residue gap (5) or the second surplus gap (6).
Described First Transition fillet (7) and the second knuckle (8) is easy to first side (3) and second side (4) point
It does not coincide and is affixed with blade (13) or runner part (14), hand-held through hole (9) is easy to carry and use in detection process.
Technique effect
1st, the present invention is not on the premise of design drawing and manufacturing process is changed, by setting the first different gap surpluses
Meet different surplus requirements with the second gap margin value, can accurately judge whether weld seam fillet relief grinding surplus meets to want
Ask, cost is cheap, simple and easy.
2nd, for the present invention on the premise of production process is not changed, avoid causes the relief grinding time because relief grinding surplus is excessive
It is long, effectively reduce relief grinding cost of labor and production cycle, while it also avoid because relief grinding surplus is too small cause it is secondary
Influence of the thermal weld stress to runner mother metal and weld seam, improves product quality, simplifies production procedure, reached cost efficiency
Purpose.
3rd, the present invention is made simple, and easy to use, operator and inspector can directly be used by simple training, is changed numerous
For letter, easy quantizing examination, unnecessary coordination and communication are avoided, improve production efficiency, and the invention is versatile,
Easy to spread, same set of model is available for different units to use.
