Embodiment
Hereinafter, describing Leeb Hardness Tester of the present invention in detail with exemplary embodiment with reference to the accompanying drawings detects with fixture and Leeb Hardness Tester pick-up unit.
Fig. 1 shows according to Leeb Hardness Tester of the present invention and detects the front view by an exemplary embodiment of fixture; Fig. 2 shows the vertical view corresponding with Fig. 1 exemplary embodiment; Fig. 3 shows the partial enlarged view of the regulon in Fig. 1.It should be noted that, 3 groups of regulons that evenly arrange have been shown in Fig. 2, and in view of 3 groups of regulon structures similar, so only show one group of regulon in Fig. 1.
As shown in Figure 1 to Figure 3, in one exemplary embodiment of the present invention, Leeb Hardness Tester detects and comprises base 1, be fixedly installed on concentrically with respect to one another outer sleeve 6 and inner sleeve 7, the regulon on the upper surface of base 1 and compress rod member 4 with fixture.
Wherein, base 1 has smooth upper surface, on this upper surface, can secure bond have outer sleeve 6 and inner sleeve 7, and sample to be tested 2 is positioned on this upper surface and is positioned at inner sleeve 7 inside.For example, base be shaped as rectangular parallelepiped or right cylinder, the weight of base can be greater than 5kg, also can be for being greater than 3kg.
Outer sleeve 6 has the first conduit extending on three circumference that are evenly opened in this outer sleeve 6 and along the short transverse (as the above-below direction in Fig. 1) of this outer sleeve 6.Inner sleeve 7 has quantity and position second conduit corresponding with the first conduit of outer sleeve 6.That is to say, inner sleeve 7 also has on three circumference that are evenly opened in this inner sleeve 7, extends and second conduit corresponding with the position of the first slideway 9 along the short transverse of this inner sleeve 7.
Regulon comprises main body block 3, ramp way, two tooth bars 8, elastic supporting member for supporting optical member 5, slideway 9.Wherein, main body block 3 is run through with the direction that the short transverse of outer sleeve 6 is acute angle in ramp way edge, and is formed with internal thread in the whole length of ramp way.The position of the close outer sleeve 6 of ramp way is position near inner sleeve 7 higher than it.A toothed rack in two toothed rack 8 is arranged on the inwall of outer sleeve 6 along the bearing of trend (as the above-below direction in Fig. 1) of the first conduit, it is upper that another tooth bar is set in the lateral surface side of the inwall of outer sleeve (towards) of main body block 3, and two toothed rack 8 are intermeshing.Slideway 9 is arranged on the outer wall of inner sleeve 7 along the bearing of trend (as the above-below direction in Fig. 1) of the second conduit.Elastic supporting member for supporting optical member 5(for example, spring leaf) one end be fixedly installed in main body block 3, the other end of elastic supporting member for supporting optical member 5 is supported on slideway 9.
For example compress rod member 4(, hold-down bolt) through ramp way and compress on the external peripheral surface of rod member 4, be formed with can with the external thread of described screw-internal thread fit.The one end that compresses rod member 4 is positioned at inner sleeve 7, as the compression end for compressing the sample to be tested 2 on the described upper surface that is positioned over base 1; The other end of clamping screw is positioned at outside outer sleeve 6, as the adjustable side for regulating.
Detect with for fixture for the Leeb Hardness Tester of this exemplary embodiment, its using method can be: sample to be tested 2(also be can be described as to test specimen to be measured) face to be detected keep flat to base 1; The main body block 3 of inwardly pressing regulon, elastic supporting member for supporting optical member 5 compresses, and two toothed rack 8 separate, the main body block 3 of regulon slides up and down, after unclamping to target bit, elastic supporting member for supporting optical member 5 engages two toothed rack 8 to the outside power of main body block 3 of regulon, and the main body block 3 of regulon is fixing; Thereby the inside precession of all compression rod members 4 is clamped sample to be tested 2.Can adopt Leeb Hardness Tester to test the hardness of test specimen to be measured.
That is to say, under the resiliency supported effect of elastic supporting member for supporting optical member 5, be positioned at tooth bar in main body block 3 and the tooth bar that is positioned on outer sleeve 6 is engaged with each other, thereby can fix by main body block 3 with through the position of the compression rod member 4 in main body block 3.In the time need to regulating the height of regulon, can or compress rod member 4 to main body block 3 and apply the acting force from outer sleeve 6 to inner sleeve 7 directions, so that elastic supporting member for supporting optical member 5 is compressed, two toothed rack depart from each other simultaneously, then, apply along the acting force of short transverse (as the above-below direction in Fig. 1) to main body block 3 or compression rod member 4, by the slip of elastic supporting member for supporting optical member 5 in slideway 9, cell moving to be regulated is to target location, remove acting force, two toothed rack engage again, and regulon is fixed.In addition,, by turning the compression rod member 4 coordinating with the ramp way of regulon, can regulate and compress the length of rod member 4 in inner sleeve 7, thereby can compress the sample to be tested of different size 2.
In exemplary embodiment of the present invention, the number of degrees that tilt to lead to the acute angle between edge and the short transverse of outer sleeve 6 are preferably 50～80 DEG C, that is to say, the angle of clamping screw and horizontal direction is 10～40 DEG C, thereby can (for example provide both direction to sample to be tested 2 simultaneously, horizontal direction and vertical direction) snap-in force, this is equivalent to adopt coupling and the method for compacting to improve the inertia of test specimen to be measured, its effect is equal to the actual mass that improves test specimen to be measured.But, the invention is not restricted to this, between logical edge and the short transverse of outer sleeve 6, be acute angle as long as tilt.
In exemplary embodiment of the present invention, the quantity of the first conduit, the second conduit, regulon, compression rod member 4 equates.And preferably, the quantity of the first conduit, the second conduit, regulon, compression rod member 4 all can be 3～6.But, the invention is not restricted to this, as long as the quantity of the first conduit, the second conduit, regulon, compression rod member 4 is not less than respectively 3.
Another aspect of the present invention provides a kind of Leeb Hardness Tester pick-up unit.Described Leeb Hardness Tester pick-up unit comprises Leeb Hardness Tester, and described Leeb Hardness Tester pick-up unit also comprises the Leeb Hardness Tester detection fixture with structure described above.
In sum, Leeb Hardness Tester detection of the present invention is carried out hardness measurement with sample and workpiece that fixture and Leeb Hardness Tester pick-up unit are applicable to various shape, size and weight, and has advantages of that clamping force is large, easy to operate, testing accuracy is high; Especially the 3kg of parts and test button be less than to(for) quality, the present invention can significantly improve its lee ' hardness accuracy of detection.
Although described the present invention with exemplary embodiment by reference to the accompanying drawings above, those of ordinary skill in the art should be clear, in the case of not departing from the spirit and scope of claim, can carry out various amendments to above-described embodiment.
