Description
Technical field
The utility model belongs to oil & gas equipment detection field, relates to a kind of lee ' hardness and detects stationary fixture.
Background technology
In order to ensure that petrochemical equipment is on active service safely, needing regularly or depending on feelings, hardness determination being carried out to petrochemical equipment.Leeb Hardness Tester is little, easy to use with its volume, becomes the most important method of on-the-spot hardness determination.Leeb Hardness Tester is primarily of main frame and percussion mechanism composition.During detection, percussion mechanism is vertically positioned over surface of the work, after pressing releasing means, impact body impacts surface of the work, obtains hardness number.
Although Leeb Hardness Tester is easy to use, its operate miss is one maximum in various sclerometer.Except the environmental factors such as self reason and temperature such as sclerometer impact body wearing and tearing, a major reason is that Leeb Hardness Tester requires that percussion mechanism is perpendicular to surface of the work in use, but during in-site measurement, even if surface of the work is smooth, still because whether the location of workpiece (eminence, spacing), sclerometer impact direction (impact up and down, impact to the left and right), operating personnel's ancon have the factors such as support, when cannot ensure that releasing means is pressed, impact body is perpendicular to surface of the work.So be necessary to provide a kind of fixture, ensure that percussion mechanism is vertical with measuring object.
Utility model content
The purpose of this utility model is to provide a kind of lee ' hardness and detects stationary fixture, when lee ' hardness detects, uses this fixture, for the measuring object of surfacing, and the error produced because sclerometer is not orthogonal to measuring object surface when effectively can reduce operation.
For achieving the above object, the utility model adopts following technical scheme:
A kind of lee ' hardness detects stationary fixture, comprise the first pretension block, the second pretension block, bolt and handle, measured workpiece and two are disposed with for clamping the fixed block of percussion mechanism between first pretension block and the second pretension block, one end of handle is fixed on the first pretension block, the other end of handle offers screw thread mouth, and bolt is connected with the second pretension block through threaded hole.
Each fixed block offers one for clamping the trapezoid-shaped openings bottom percussion mechanism, and two trapezoid-shaped openings are oppositely arranged.
Offer tapped blind hole in the middle part of described second pretension block, the second pretension block adopts with bolt and is threaded.
The medium position of described second pretension block and two fixed blocks fits.
Described bolt is aerofoil profile bolt.
Described aerofoil profile bolt length is 50-200mm.
Described first pretension block is rectangular structure, and the first pretension block and handle adopt weld or be threaded fixing.
The thickness of described two fixed blocks is 10-25mm.
The material of described fixed block, the first pretension block, handle, the second pretension block, bolt, percussion mechanism is carbon steel material.
Compared with prior art, the beneficial effect that has of the utility model:
1. the utility model passes through employing two fixed blocks by scleroscopic percussion mechanism bottom clamping, ensure that percussion mechanism and measured workpiece are in plumbness in test process, and than when testing in prior art, by manually fixing more accurate, the error produced because scleroscopic percussion mechanism is not orthogonal to measuring object surface when effectively reducing operation.
2. scleroscopic percussion mechanism can firmly be fixed between fixed block by the utility model, again fixed block is firmly fixed on measured workpiece on the surface, when the release-push of testing staff on percussion mechanism top operates, no matter stationary fixture is horizontal positioned or vertically places, all can not make percussion mechanism deflection, improve the accuracy of measurement.
3. the utility model is detachable, is convenient to onsite application and carries, and the lee ' hardness being applicable to surfacing workpiece detects.
Further, a middle side part upper position due to each fixed block in the utility model offers trapezoid-shaped openings, and when two fixed block combinations, sclerometer percussion mechanism can be fixed in trapezoid-shaped openings center, because opening is trapezoidal, the fixing of different-diameter percussion mechanism can be met.The laminating position of the second pretension block and two fixed blocks is positioned at the medium position of fixed block, then trapezoid-shaped openings is arranged on the position of departing from middle part of each fixed block, ensures that the center of gravity of fixed block is positioned within laminating scope.The thickness of fixed block can be set to 10-25mm, for the fixing needs of satisfied most of sclerometer percussion mechanism.
Further, bolt adopts aerofoil profile bolt, and length is 50-200mm, because length is longer, is convenient to the suitably height that raises and decline, thus makes the utility model all applicable to most of thickness measuring workpiece.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation that fixed block and sclerometer percussion mechanism are fixed.
Wherein, 1 is fixed block, and 2 is the first pretension block, and 3 is handle, and 4 is the second pretension block, and 5 is bolt, and 6 is percussion mechanism, and 7 is measured workpiece.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
See Fig. 1 and Fig. 2, the utility model comprises bolt 5, handle 3 and two are for clamping the fixed block 1 bottom scleroscopic percussion mechanism, on each fixed block 1, middle part upper position all offers trapezoid-shaped openings, the side that two fixed blocks offer trapezoid-shaped openings is staggered relatively, two trapezoid-shaped openings are for placing scleroscopic percussion mechanism 6, the top of two fixed blocks 1 is provided with the first pretension block 2 of rectangular structure, the top of two fixed blocks 1 is provided with measured workpiece 7, the below of measured workpiece 7 is provided with the second pretension block 4, second pretension block 4 offers tapped blind hole, one end of handle 3 is fixed on the first pretension block 2 by welding or being threaded, the other end of handle 3 offers screw thread mouth, bolt 5 enters the tapped blind hole of the second preload piece 4 through threaded hole.The medium position of described second pretension block 4 and two fixed blocks 1 fits.The material of described fixed block 1, first pretension block 2, handle 3, second pretension block 4, bolt 5, percussion mechanism 6 is carbon steel material or other non magnetic hard materials.
A middle side part upper position due to fixed block in the utility model offers trapezoid-shaped openings, and when two fixed block combinations, sclerometer percussion mechanism can be fixed in trapezoid-shaped openings center, because opening is trapezoidal, can meet the fixing of different-diameter percussion mechanism.Trapezoidal mouth is arranged on the middle part upper position of each fixed block, and the laminating position of the second pretension block and two fixed blocks can be made to be positioned at the medium position of fixed block, ensures that the center of gravity of fixed block is positioned within laminating scope.The thickness of fixed block can be set to 10-25mm, for the fixing needs of satisfied most of sclerometer percussion mechanism.
Described bolt 5 is aerofoil profile bolt, and length is 50-200mm, because length is longer, is convenient to the suitably height that raises and decline, thus makes the utility model all applicable to most of thickness measuring workpiece.
