Embodiment
Below in conjunction with accompanying drawing, the present invention is done further description.
A kind of magnetic caliber square; Comprise left fixed cell, right fixed cell, reading unit, dip stick band and regulate control module; Said reading unit is connected with said dip stick band and between said dip stick band and said right fixed cell, said adjusting control module is positioned at the right side of said reading unit.
Said left fixed cell and right fixed cell are respectively left magnetic support and right magnetic support; Side near the left magnetic support of said dip stick band is cambered surface side or planar side; Side near the right magnetic support of said dip stick band is cambered surface side or planar side.
Said adjusting control module comprises diameter adjustment part, fastening unit, reading spare, flexible adjustment part and base; Said diameter adjustment part, securing member, reading spare and flexible adjustment part are separately fixed on the said base; Said reading spare is a diameter reading spare; Said fastening unit is fixed said dip stick band; Said flexible adjustment part connection is also regulated said dip stick band.
Said flexible adjustment part also is connected with constant force index part, and said constant force index part is with said flexible adjustment part move left and right and show the constant force index.
Contact on the said diameter reading spare is replaced said diameter adjustment part; Dial gauge on the said diameter reading spare shows the reading when the diameter adjustment part is regulated.
Said left magnetic support and right magnetic support are respectively equipped with demagnetize spare.
Said fastening unit comprises folder chi device and nose bar spare; The said dip stick band of said folder chi device clamping; Said nose bar spare is pushed down said dip stick band.
Said flexible adjustment part is placed on the said base and through the nut adjusting and is fixed on the said base.
Said reading unit is scale reading unit, digital display meter or electronics indicator gauge.
In one embodiment; Like Fig. 1, shown in Figure 2; A kind of magnetic caliber square; Be to measure the Magnetic Measurement chi of external diameter, comprise left magnetic support 1, right magnetic support 4, steel ruler 2 and regulate control module, wherein said adjusting control module comprises diameter adjustment part, fastening unit, reading spare, flexible adjustment part and base; Said diameter adjustment part, securing member, reading spare and flexible adjustment part are separately fixed on the said base; Said reading spare is a diameter reading spare; Said fastening unit is fixed said dip stick band; Said flexible adjustment part connects and regulates said dip stick band, and in the present embodiment, the diameter adjustment part is a set screw 31, and reading spare then is a dial gauge 34, and said fastening unit comprises folder chi device 32 and nose bar spare 33; The said dip stick band of said folder chi device 32 clampings; Said nose bar spare 33 is pushed down said dip stick band, and in one embodiment, nose bar spare 33 can be the nose bar screw; Connecting spring on the horned nut 35, during rotation horned nut 35, the length of automatic adjuster spring; Move thereby drive constant force index part, in the present embodiment, constant force index part is parallel and two steel discs 36 base; When measuring, measure the error of having avoided steel ruler in measurement, to bring through keeping constant force.Simultaneously, can like demagnetize screw 41, can carry out the adjusting of magnetic as required to left and right sides magnetic support configuration demagnetize unit.
