Description
Technical field
The invention belongs to hardometer servicing unit field, is more particularly to a kind of multi-angle support hardometer firm banking.
Background technology
The test of hardness, which mainly has, surveys metal and nonmetallic two major class.Many products are required for knowing the hard of its parts
Degree, a such as mould, as hardness is inadequate, it will wear quickly；Sometimes small to one screw avoids making it should also be understood that its hardness
Into the easy slide fastener of screw thread；Now substantial amounts of electronic product shell made of plastic, also often need to survey its hardness.Survey the parameter of steel hardness
It is Rockwell hardness, the generally higher steel of hardness；Not quenched steel, cast iron, non-ferrous metal and the soft bearing of matter is surveyed to close
The parameter of golden material is Brinell hardness；The parameter of aluminium, aluminium alloy and thin-sheet metal material is surveyed Vickers hardness.Survey rubber, plastics etc.
The parameter of nonmetallic hardness can all be changed mutually Shore hardness, also known as shore hardness, various hardness, also have one kind to cry inner
Family name's hardness, mainly survey steel and use, be also used for surveying other materials, can be converted into other hardness.
Sclerometer is a kind of instrument for measuring the hardness such as rubber, plastics, metal material, is sent out first by British Xiao Er
It is bright.Striker is fallen on the surface of tried material from certain altitude using elastic resilience method and knock-oned.Striker is a tool
Cuspidated conelet, spark is often studded with tip.Hardness is represented with the height of the striker rebound measured.Sclerometer is fitted
For determining the Shore hardnes figure of ferrous metal and non-ferrous metal.For determining the hardness of rubber, plastics, metal material etc..
Shore hardness is commonly referred to as in rubber, plastic industry.
Sclerometer can hand dipping, but due to craft dynamics control be not very stable, so generally can be by one
Stand, accuracy of measurement is improved, still, existing sclerometer easily produces vibration when measuring the hardness of cylindrical parts
Test result is caused to produce larger error, and use too high for the different fixing device cost of different Element Designs be not square
Just.
In reality, often the hardness of workpiece is measured, it is general in the prior art to use, directly measured workpiece is put
Test desk is put, it is measured using hardometer, draws measurement data., can be steady for the measured workpiece of some regular shapes
Be placed on test desk, some measured workpieces in irregular shape, then need to clamp it, for spherical measured workpiece,
Due to easily rolling, the measurement to hardness brings inconvenience.

Planar part, the device is applied to the part of different sizes and shapes, there is the advantages of good reliability, applied widely.
But also there is following technical problem in above-mentioned prior art：
1. being clamped only with two support blocks, the free degree of both direction by fixed object under test also be present,
When carrying out hardness measurement, object under test can move to loose both direction, influence the measurement of hardness, or even can damage hardness
Meter.
2. be fixed using the V-arrangement supporting surface with horizontal plane with certain angle come measuring targets, itself and determinand
Body it is insufficient contact, the angle of itself and horizontal plane is a definite value, has no idea to be adjusted, can not adapt to of different shapes
The hardness measurement of object under test.
3. be fixed using above-mentioned prior art measuring targets, due to there was only two support blocks, measuring targets
Center can not accurately position so that during measurement, measurement head and object under test center out of plumb can be caused, when there is load loading
When, easily cause steel ball and measurement gauge head to deviate because measurement gauge head is not orthogonal to workpiece calibration center, hardness measurement number
According to distortion, the situation of the instrument damage such as gauge head rupture or the bending of internal lever deformation can occur when serious.
The content of the invention
In order to solve the above-mentioned technical problem, the present invention provides a kind of multi-angle support hardometer firm banking, existing to solve
There is technology can not stablize fixed object under test, object under test center contacts with support when measurement head out of plumb, measurement spheroid and do not filled
Grade problem.
The present invention basic technology scheme be：A kind of multi-angle support hardometer firm banking, including regulating block, screw rod,
Base, sliding block, the regulating block are fixedly connected with screw rod, and screw rod is located in chassis interior, and sliding block is set on screw rod, its feature
It is：Also include supporting plate, rotating wheel, the supporting plate is fixedly connected with rotating wheel, and clamp screw is additionally provided with the rotating wheel
Nail；The sliding block is provided with Y shape support frame, and the Y shape support frame supports supporting plate, and supporting plate is rotatablely connected with Y shape support frame.
The present invention base case operation principle be：When measuring object under test hardness, regulating block is adjusted, screw rod, which rotates, to be driven
Sliding block moves, and sliding block is fixedly connected with support frame, support frame movement, support frame and supporting plate rotation connection, now supporting plate with
Sliding block movement；It is different according to the shape of object under test behind the position for regulating supporting plate, adjust rotating wheel, rotating wheel and branch
Fagging is fixedly connected, and rotating wheel can rotate around support frame, and therefore, rotor plate rotates, and we just can adjust during hardness test
The angle of rotor plate and horizontal plane, to adapt to object under test of different shapes；After the angle for regulating supporting plate, set on rotating wheel
There is holding screw, screw holding screw, the angle of fixed rotor plate and horizontal plane, you can complete the Set and Positioning of article to be measured.
Using this programme, achievable supporting plate is adjustable with horizontal plane angle, is suitable for the hardness test of object under test of different shapes, letter
It is single practical.
Further, described supporting plate quantity is four, is respectively distributed to the four direction of base.Using four supporting plates
Measuring targets carry out position and fixed so that fixation is more reliable and stable, is swung even if there is slight impact, object under test
Also will not shake the phenomenon dropped out, and compared with the technical scheme in background technology, clamping is fixed more stable reliable.
Further, the base upper surface is additionally provided with four guide grooves, and support frame is arranged in guide groove.Using guiding
Groove, supporting plate is prolonged guide groove translation, adjust spacing, to adapt to the fixation of different size of object under test, be easy to subsequently survey
Amount process.
Further, the base center position is additionally provided with two orthogonal grooves.Heart setting two is orthogonal in the base
Groove, when being easily installed base so that measurement head can conveniently be directed at the center of base, be easy to ensure that measurement head can be aligned during measurement
Base center, hardness measurement data distortion is reduced, gauge head rupture or the bending of internal lever deformation etc. can occur when serious
The situation of instrument damage.
Further, the supporting plate uses hard metal.When measuring targets carry out hardness test, due to object under test
Hardness it is each variant, the hardness of some objects is larger, produces damage to supporting plate contact site unavoidably, using hard metal,
The damage to supporting plate can be reduced so that the service life of whole device increases.
In summary, beneficial effects of the present invention are：
