Abstract
The utility model discloses a compression spring loaded hygrometric sand mould surface hardness gauge comprising a measuring bar (1), a measuring head (2), a gauge (3) and a rack drive mechanism (4). The compression spring loaded hygrometric sand mould surface hardness gauge is characterized in that the measuring bar (1) is arranged in a measuring bar barrel (5), the measuring head (2) is arranged below the measuring bar (1), and the upper end of the measuring bar (1) is contacted with a compression spring (6) arranged in the measuring bar barrel (5), the upper end of the measuring bar barrel (5) is provided with a force adjusting bolt (7), the lower end of the measuring bar barrel (5) is provided with a base plate (8), the middle part of the measuring bar barrel (5) is provided with a locking pin (9), and the gauge (3) is arranged on the measuring bar barrel (5) and is connected with a rack drive mechanism (4). Compared with the traditional hardness gauge, the compression spring loaded hygrometric sand mould surface hardness gauge has the advantages of compact structure, convenience in carry, wide application range, strong resolution capability, avoidance of damage to a casting mould and good measurement stabilizing property.
Description
Technical field
The utility model relates to a kind of improvement of hygrometric sandbox skin hardness meter; Specifically a kind of stage clip loaded type hygrometric sandbox skin hardness meter; Be applicable in the Foundry Production high, medium and low specific pressure commonly used, the test of various formative methods and all kinds of clay-beaded sand hardness of sand mould surface.
Background technology
The hygrometric sandbox skin hardness meter that uses at present is made up of above-mentioned sclerometer measuring staff, gauge head, extension spring, rack gear, instrument; Though existing widespread usage; But also there is following deficiency: the one, gauge head top is circular, and the spherical crown radius is little, differentiates a little less than the sand mold consolidation degree ability; The scope of application is little, also has the problem that is prone to the infringement casting mold; The 2nd, utilize extension spring to load, friction force is big, and instrument power value is unstable.
Summary of the invention
The purpose of the utility model is to provide a kind of compact conformation, and is easy to carry, applied widely, and resolution characteristic is strong, avoids casting mold to damage the stage clip loaded type hygrometric sandbox skin hardness meter that the measured value stability is good.
For reaching above purpose, the technical scheme that the utility model is taked is: this stage clip loaded type hygrometric sandbox skin hardness meter is made up of measuring staff, gauge head, instrument, rack gear; It is characterized in that measuring staff is located in the measuring staff tube, divide on the gauge head and contact that accent power bolt is established in measuring staff tube upper end with the stage clip that is located at the measuring staff tube; Base plate is established in the lower end, and locking pin is established in the centre, and instrument is installed on the measuring staff tube; And be connected with rack gear, when gauge head is pressed into the sand mold surface, the stage clip on measuring staff compression top; The stage clip distortion passes to gauge pointer again through rack gear.The utility model is also implemented through following measure: described gauge head, top are taper, and the bottom is a spherical crown, and its spherical crown radius is 20 millimeters.When using the utility model, with finger press gauge head three times, whether the inspection pointer returns zero earlier, and like nulling not, available hand-screw moves the instrument decorative cover, and it is zero that pointer is returned.During test, catch the measuring staff tube gently to be pressed on the tested sand mold surface with thumb and forefinger, the sclerometer base plate is closely contacted with tested sand mold surface, at this moment, the indicated reading of pointer is the hardness number of institute's measuring point.At this moment, can click locking pin, pointer is fixed in the hardness number place that surveys, run through measured value after, unclamp locking pin, make pointer recover zero-bit.
The beneficial effect of the utility model is: compare with present sclerometer, have compact conformation, easy to carry, applied widely, resolution characteristic is strong, avoids casting mold to damage the advantage that the measured value stability is good.
