Abstract
The utility model relates to a portable sclerometer which is used for measuring the surface hardness of the metal material. The utility model connects an impact piston and a spring into integration, and an impact vibration system is formed. Therefore, the effect of the gravity on the measure precision is reduced in different measure angle, and the rotation of the piston in the circumferential direction is limited to reduce the error resulted from the imprecision of the mechanical working to the measure. The utility model also uses a snap ring type lifting mechanism and a positioning releasing piston to ensure the consistency of the lifting and releasing height of the measure every time.
Description
The portable hardometer that is used for the measuring metallic materials skin hardness.
The portable hardometer of present domestic use mainly is the EQUOTP hardness-testing device that Switzerland PROCEQ company produces, and this sclerometer mainly is made up of ramming piston, strike spring, orienting sleeve, three-jaw hoisting gear, release-push, external microcomputer etc.During test, the ratio input computing machine of the speed of the speed when piston is hit free resilience behind the measured material during with bump, the hardness number of display material after data processing, its measuring accuracy can reach 0.8%.But this sclerometer is because piston and spring have the 2-3cm distance, separate, piston is once penetrating from spring, be free movement, the positioning of rotating of not having circumferencial direction when ejaculation and resilience, can in sleeve, rotate, piston and orienting sleeve are because any point flexibility that machine work causes like this, ellipse garden degree etc. all can make between the two at different relative positions, produce the indefinite friction force of size on the different test angle, have a strong impact on measuring accuracy, so this sclerometer is high to the machine work accuracy requirement of part, not only processing charges is expensive, and the present machine work level of China also is difficult to reach.Speed when simultaneously its piston of sclerometer of this piston and spring separate type freely clashes into resilience is subjected to gravity effect bigger, so also can influence its accuracy when test angle is big.The EQUOTP hardness-testing device is after its three-jaw hoisting gear is caught piston in addition, pressured next top release-push to eject piston, easily like this causes that hoisting gear is unnecessary to move down, and shortens and ejects distance, causes measuring error.
The utility model is intended to overcome above-mentioned disadvantage, provides a kind of processing and manufacturing simple, can also guarantee the portable hardometer of certain measuring accuracy simultaneously.
Composition of the present utility model includes oscillator plug (7), magnetic induction coil (8), orienting sleeve (6), vibrating spring (5), promote spring (1), the externally connected portable machine (9) etc. that declines, the location release end cap (2) that it is characterized in that oscillator plug (7) and vibrating spring (5) and be contained in the orienting sleeve fuses, hoisting gear adopts snap ring type lifting arm (3), the lifting arm upper end links to each other with afterburning cover (4), the lower end is a clasp that can fasten oscillator plug (7) top spheroid, (see figure 2) has four grooves that vertically lose heart on orienting sleeve (6) inwall.Its structure and principle of work are: orienting sleeve (6) top is fixed with the location and discharges end cap (2), vibrating spring (5) is housed in the orienting sleeve, spring lower end and oscillator plug (7) are connected as a single entity, the upper end discharges the end cap top with the location and links to each other, and oscillator plug (7) can move up and down in orienting sleeve together with spring (5).Snap ring type lifting arm (3) vertically passes the location and discharges end cap (2), its lower end is a clasp, the upper end links to each other with afterburning cover (4), lifting spring (1) is housed in afterburning the overlapping, overlap (4) along the orienting sleeve outer wall to pressing down reinforcing, then spring (1) is compressed, and snap ring type lifting arm (3) also moves downward thereupon.Magnetic induction coil (8) is equipped with in orienting sleeve outer wall bottom, in the oscillator plug permanent magnet is housed.When measuring material hardness, with the afterburning cover of hand (4), promoting spring (1) is compressed, snap ring type lifting arm (3) moves downward, after coming downwards to clasp and fastening spheroid on the oscillator plug (7), under the effect that promotes spring (1) force of compression, snap ring type lifting arm (3) is with the oscillator plug (7) that is fastened, move upward simultaneously with reinforcing cover (4), compressed vibrating spring (5) simultaneously, when going upward to, oscillator plug (5) is stuck when the location discharges end cap (2) lower end part, and lifting arm (3) also continues to rise, at this moment oscillator spheroid is beyond the Great Wall deviate from the clasp of lifting arm, under the effect of the vibrating spring (5) that compresses, impact tested metal downwards, behind the sintered carbide ball and metal material surface bump of oscillator plug with its head, produce the motion that resilience makes progress again, the vibrational system that the metal of different hardness can make oscillator plug and vibrating spring fuse produces different yo-yo effects, this different yo-yo effect is that the induction electromotive force by caused by relative motion between the magnetic induction coil (8) that is contained in permanent magnet in the oscillator plug and orienting sleeve (6) outside reflects, see Fig. 3, e is an induction electromotive force, t

The utility model since oscillator plug and vibrating spring be connected as a single entity, so limited of the rotation of oscillator plug at garden Zhou Fangxiang, so just can overcome owing to the oscillator plug rotate cause its with orienting sleeve between be in different relative positions and produce of the influence of different friction force test accuracy, thereby reduced because the not high influence of machine work precision measuring accuracy.Simultaneously, what the test value of this instrument was got is the peak swing value of first vibration period after the piston slap resilience, and this vibration state depends primarily on spring and piston slap screen resilience in the vibrational system of vibrating spring and oscillator plug one, be subjected to bigger the coming of gravity effect compared with original with the do not link to each other free resilience of piston of spring, the test value that the utility model is got is subjected to gravity effect much smaller, so particularly having when testing under the situation of individual angle with vertical direction, can alleviate the influence of action of gravity to measuring accuracy greatly, the disappointing groove of opening on the orienting sleeve inwall also can reduce the friction force between piston and the inwall.In addition, the utility model adopts snap ring type hoisting gear and location release plunger, has guaranteed the consistance of the lifting release altitude of each test, to improve accuracy of test.After measured, though the utility model is not very too high to the machine work requirement, but still measuring accuracy is reached more than 0.9%.
