Description
Technical field
The utility model relates to experiment of hardness device field, more particularly to a kind of test impression positioning of Vickers pyramid hardness testing machine
Device.
Background technique
The detectable range of Vickers hardness test method is very wide, other than especially small and thin test layer sample, can cover
Cover all metal hardness detections.Compare with Bu Shi, Rockwell hardness method, Vickers hardness impression obtained is not put to the test power
Influence, and have similar geometry shape, to the identical material of any property after change trial power obtained hardness number one
Cause property is very good.The square cone diamond penetrator that the pressure head used in Vickers hardness detects is 136 °, so it is pressed
Trace is clear-cut square, and cornerwise measurement accuracy is high, ensure that the reliability of hardness measurement precision.
For the samples such as steel, copper and copper alloy, Vickers hardness test method standard requires carrying out Vickers hardness inspection
When survey, impression center to sample Edge Distance should be not less than 2.5 times of impression catercorner length；The spacing at two adjacent indentations centers
From at least should be cornerwise 3 times of impression for steel, copper and copper alloy.And also to Indentation position in portioned product standard
Make concrete regulation, as we produce the common API SPEC 5L product standard of detection require indentation edge away from sample edge away from
From for 1.5~2.0mm；Dao Daer (TOTAL) Products code requirement indentation edge away from sample Edge Distance be 0.5 ±
0.25mm。
Currently, common Vickers pyramid hardness testing machine, does not have testing position automatic positioning function, experimenter's naked eyes can only be leaned on to sentence
Disconnected and placed indentation position, impression positioning accuracy is poor, is easy to appear deviation, will affect the accuracy of test result, and be not inconsistent
Close requirement of the portioned product standard to Indentation position accuracy.Therefore, it is necessary to a pressure is developed on the basis of hardness tester
Trace accurate positioning device, to realize that indentation hardness is accurately positioned.
Summary of the invention
To solve the problems, such as above-mentioned technology, the purpose of the utility model is to provide one kind can satisfy testing standard
It is required that while efficient accurate positioning device is carried out to the Vickers pyramid hardness testing machine test impression in using.
To achieve the above object, the technical solution adopted in the utility model is that a kind of Vickers pyramid hardness testing machine test impression is fixed
Position device, including the snap ring and positioning claw being arranged on Vickers pyramid hardness testing machine anvil block, it is solid that shown snap ring passes through fixed jackscrew
It is scheduled on anvil block；The positioning claw is flexibly connected by pin with snap ring outer wall and horizontal is on anvil block.
Described positioning claw one end is to set reeded root to be adapted to connection with the tongue of snap ring outer wall, and the other end is freely
End.
The positioning claw is that root to free end width is tapered, thickness gradually thin smooth slab organization.
It is arc at the top of the free end of the positioning claw.
The positioning claw is equipped with positioning claw A and positioning claw B, is separately connected and is correspondingly arranged on the snap ring outer wall
On two tongues.
The positioning claw A and positioning claw B are respectively and movably connected on be correspondingly arranged on snap ring outer wall two tongues,
Another positioning claw is lifted using positioning claw A or positioning claw B according to accepted standard when work.
The length of the positioning claw A is 68mm, and the length of the positioning claw B is 67mm.
The effect of the utility model is: the device makes test result meet product to realize that indentation hardness is accurately positioned
The indentation edge that standard API SPEC 5L is required is 1.5~2.0mm away from sample Edge Distance and Dao Daer (TOTAL) company produces
The regulation that the indentation edge of product code requirement is 0.5 ± 0.25mm away from sample Edge Distance, while improving test efficiency.

Specific embodiment
The utility model is further elaborated with reference to the accompanying drawings and detailed description.
As shown in Figures 1 to 4, the structure of the Vickers pyramid hardness testing machine test impression accurate positioning device of the utility model
Be: the positioning device includes a fixing clasp 1, positioning claw A2 and positioning claw B3, jackscrew 4 and two pins 5.Positioning
The design of device needs high-precision linear cutter, and each components need to be fitted close, and and hardness tester
Anvil block also wants close proximity, 1 internal diameter of fixing clasp by wire cutting Precision Machining and with hardness tester anvil block outer diameter one
It causes, to realize that the two is fitted close.
As shown in Figures 5 to 7, fixing clasp 1 is fixedly connected by jackscrew 4 with hardometer anvil block, requires when installation to fix
Snap ring 1 and hardness tester anvil block are in close contact, and cannot have movement after fastening, and ensure two positioning claw A or positioning card
Pawl B is fitted closely after putting down with hardometer anvil block.
Positioning claw A and positioning claw B are connected by pin 5 with fixing clasp 1.To avoid hardness specimens edge hairiness
Thorn influences and positioning claw A or positions claw B and fit closely, and Design Orientation claw A and when positioning claw B will positioning claw A
It is thinned with part has been carried out with hardometer anvil block binding face at the top of positioning claw B, prevents hardness specimens burrs on edges from influencing hardness
Impression is accurately positioned.In order to be suitable for the band inside and outside wall testing position of radian sample, processing at the top of positioning claw A and positioning claw B
Camber is that line contacts to ensure positioning claw A and position the top claw B with hardness specimens.It is connected respectively with fixing clasp 1
Positioning claw A and positioning claw B, wherein 1 positioning claw A or will position claw B and pull above hardometer anvil block, and therewith
It fits closely, abuts against sample on positioning claw A or positioning claw B curved end when test, it is certifiable in this way to beat in sample
On indentation hardness meet respective standard requirement.By exchanging positioning claw A and positioning the position of claw B, it can be achieved that 2 kinds of tests
The mutual conversion of Indentation position.
When using the indentation edge of product standard API SPEC 5L requirement away from sample Edge Distance for 1.5~2.0mm, choosing
Positioning claw A is selected as positioning claw；The indentation edge required using product standard Dao Daer (TOTAL) is away from sample Edge Distance
When for 0.5 ± 0.25mm, selective positioning claw B is as positioning claw.
