The inspection tool has the beneficial effects that the pinhole size inspection card and the region dividing card are used together to detect the size and quantity of the pinholes simply, conveniently, rapidly and accurately, a new inspection tool is provided for detecting severity of the pinholes in the machined surface of the aluminum alloy casting, and particularly, the simple, accurate and practical inspection tool for detecting severity of the pinholes in the machined surface of the aluminum alloy casting is provided for aluminum alloy casting manufacturers and factories having demands on aluminum alloy castings.
Description
Technical field
The utility model relates to the instruments of inspection field of machining surface, especially a kind of aluminium alloy castings machining surface aperture size instruments of inspection.
Background technology
Aluminium alloy is a most widely used class nonferrous materials in industry, and along with worldwide energy problem is more and more serious, light-weight design has become an important means that reduces the energy.But light-weighted prerequisite must meet mechanical property and product usability, foundry goods interior tissue whether densification and foundry goods machine adds the key that surface pinholes size is mechanical property quality.According to aluminium alloy castings machining surface aperture size method of inspection regulation in ISO10049 international standard < < aluminium alloy castings pinhole rate range estimation rating method > >: 4.4 test conditions are to test by bore hole or with the magnifier that enlargement factor is no more than 10 times when measured hole hole dia (only adopt).But aluminium alloy castings machining surface aperture size is difficult to be no more than in bore hole or by enlargement factor under 10 times of magnifieres by vernier caliper measurement pinhole diameter size in actual production, unless and measured aluminium alloy castings machining cannot be measured while being endoporus periphery or other special surfaces foundry goods is carried out existing in destructive test, particularly testing process other secondary mass defects such as scuffings grade.So according to stipulating in < < aluminium alloy castings pinhole rate range estimation rating method > > that the method for inspection is large to batch production aluminium alloy castings machining surface aperture size check difficulty, proving time long, lack unified basis for estimation, verify error is large, reviewer's technical ability requires high defect.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, and a kind of aluminium alloy castings machining surface aperture size instruments of inspection simple in structure, convenient to use is provided.
The utility model solves the technical scheme that its technical matters adopts: this aluminium alloy castings machining surface aperture size instruments of inspection, mainly comprise aperture size check card and region division card, on aperture size check card, be provided with from top to bottom diameter and progressively become several large contrast pores, region is divided card and is provided with the square region lattice that permutation is arranged, and the square region lattice number of dividing card lastrow with the contrast pore number of the same diameter of a line with region on aperture size check card is identical.
The diameter of described contrast pore is followed successively by 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.2mm, 1.5mm, 2.0mm, 2.5mm, 3mm from top to bottom, is divided into 15 grades.
The size of described square region lattice is the square frame of 10mmX10mm.
Described aperture size check card and region are divided and are blocked by 0.1mm the transparent membrane to 0.2mm, or the thick transparent plastic sheet of 2mm is made.
Described aperture size check card and region are divided cartoon and are crossed laser printing, or laser engraving is made.
The effect that the utility model is useful is: the utility model is divided being combined with of two cards of card by aperture size check card and region, can be simple, convenient, fast, the accurate detection that must complete ISO10049 international standard < < aluminium alloy castings pinhole rate range estimation rating method > > aperture size and quantity, for the check of the aluminium alloy castings machining surface pin hole order of severity provides a kind of new instruments of inspection, in particular for aluminium alloy castings manufacturer and aluminium alloy castings, use producer to provide simple to the evaluation of the pin hole order of severity, accurate and the practical instruments of inspection.
Accompanying drawing explanation
Fig. 1 is aperture size check card structural representation of the present utility model;
Fig. 2 is that card structure schematic diagram is divided in region of the present utility model.
Description of reference numerals: aperture size check card 1, card 2 is divided in region, contrast pore 3, square region lattice 4.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in the figure, this aluminium alloy castings machining surface aperture size instruments of inspection, mainly comprise aperture size check card 1 and region division card 2, on aperture size check card 1, be provided with from top to bottom diameter and progressively become several large contrast pores 3, according to order of severity grade regulation in ISO10049 international standard < < aluminium alloy castings pinhole rate range estimation rating method > >, the diameter of contrast pore 3 is followed successively by 0.1mm from top to bottom, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.2mm, 1.5mm, 2.0mm, 2.5mm, 3mm, be divided into 15 grades.Region is divided card 2 and is provided with the square region lattice 4 that permutation is arranged, according to order of severity grade in ISO10049 international standard < < aluminium alloy castings pinhole rate range estimation rating method > >, describe and evaluate, the size of square region lattice 4 is made as to the square frame of 10mmX10mm, in order to measure quantity and the size of visible pin hole on the surface in square frame.Square region lattice 4 numbers of dividing card 2 lastrows with contrast pore 3 numbers of the same diameter of a line with region on aperture size check card 1 are identical.Aperture size check card 1 and region division card 2 be the transparent membrane to 0.2mm by 0.1mm, or the thick transparent plastic sheet of 2mm is made.Card 2 is divided by laser printing in aperture size check card 1 and region, or laser engraving is made.
