Abstract
The utility model discloses a kind of coupon detection draw a lattice tool, it is intended to solve coupon draw lattice it is inconvenient, easily generate error deficiency.The utility model includes pedestal, pedestal upper surface is equipped with row's mounting hole close to left and right sides position, pedestal side is equipped with several locking holes connected with mounting hole one-to-one correspondence, scribing line column is fitted in mounting hole, the end of scribing line column stretching mounting hole is equipped with the scribe head of tapered structure, lock-screw is connected in locking hole, lock-screw is closely connected on scribing line column outer wall.This coupon detection draws lattice tool and greatly facilitates coupon stroke lattice operation, and scribing line is precisely not likely to produce error.
Description
Technical field
The utility model is related to one kind to draw lattice tool, more specifically, it relates to which lattice tool is drawn in a kind of detection of coupon.
Background technology
The tensile property of metal material includes tensile strength, yield strength, elongation percentage, section shrinkage soldier, is to weigh material
The most important index of performance.Wherein, elongation percentage and the contraction percentage of area be after tensile test bar is pulled off, it is long by measuring coupon
Spend what is calculated with fracture diameter.Most easy measuring method is exactly straight using the tensile elongation of calliper coupon and cross section
Diameter.Therefore it needs to carry out drawing lattice on coupon, mostly pure craft at present draws lattice, needs to mark at least 6 scales on coupon, obtain
To 3 groups of data, to measure the length after elongation, the elongation percentage of coupon is calculated.Lattice are drawn in pure craft, and scale need to be compareed when drawing lattice
Ruler, it is inconvenient, and easily generate error.
Utility model content
The utility model overcomes coupon and draws that lattice are inconvenient, easily generates the deficiency of error, provides a kind of inspection of coupon
It surveys and draws lattice tool, it greatly facilitates coupon and draws lattice operation, and scribing line is precisely not likely to produce error.
In order to solve the above-mentioned technical problem, the utility model uses following technical scheme：Lattice tool is drawn in a kind of coupon detection,
Including pedestal, pedestal upper surface is equipped with row's mounting hole close to left and right sides position, and pedestal side is equipped with several and peace
The locking hole that hole corresponds connection is filled, scribing line column is fitted in mounting hole, the end that scribing line column stretches out mounting hole is equipped with
The scribe head of tapered structure, lock-screw is connected in locking hole, and lock-screw is closely connected on scribing line column outer wall.
The testing requirements of the distance between pedestal upper installing hole coupon are previously set, and coupon detection is drawn lattice tool and used
When, pedestal is held, lattice are drawn by scribe head towards coupon and on coupon surface, without with reference to graduated scale, easy to operate, scribing line
Precisely, it is not likely to produce error.Column of crossing carries out locking positioning by lock-screw, and connection positioning is reliable.
Preferably, locking hole is arranged on pedestal front and rear sides, adjacent two locking hole one is arranged on pedestal leading flank,
Another is arranged on pedestal trailing flank.Locking hole stagger setting prevents from adjacent two lock-screw to be connected in locking hole doing
Relate to phenomenon.
Preferably, often there are three the settings of row's mounting hole.It is reasonable that hole number setting is installed, to adapt to testing requirements.
Preferably, the scribe head top of cone structure is arranged on installation axially bored line extended line.This structure setting has
Conducive to the precision for improving scribe head stroke lattice.
Preferably, pedestal lower surface is equipped with sliding slot, be slidably mounted in sliding slot two for cover conjunction mounting hole cunning
Plate, two slide plates are symmetrical set, and sliding slot two side outer edge position is equipped with the positive stop strip for limit skateboard, two slide plate phases
Opposite end is equipped with the driving lever of L-shaped, and two driving levers are oppositely arranged.It crosses after column installation, slide plate is driven to be slided in sliding slot by driving lever,
Make slide plate that mounting hole lower ending opening is covered conjunction completely, prevent scribing line column from slipping away mounting hole, then rotation lock screw is to column of crossing
It is locked.And finger can be inserted in the L-shaped driving lever being oppositely arranged to two when lattice operation is drawn, and prevent the base that slips away
Seat, it is easy to operation.
Compared with prior art, the beneficial effects of the utility model are：Coupon detection draws lattice tool and greatly facilitates coupon
Lattice operation is drawn, scribing line is precisely not likely to produce error.

Specific embodiment
Below by specific embodiment, and with reference to attached drawing, the technical solution of the utility model work is further specifically retouched
It states：
Embodiment：Lattice tool is drawn in a kind of coupon detection（Referring to attached drawing 1, attached drawing 2）, including pedestal 1, pedestal upper surface is close
Left and right sides position is equipped with row's mounting hole 2, often arranges there are three mounting hole settings, pedestal side is equipped with several and installation
Hole corresponds the locking hole 3 of connection, and scribing line column 4 is fitted in mounting hole, and the end that scribing line column stretches out mounting hole is equipped with
The scribe head 5 of tapered structure, the scribe head top of cone structure are arranged on installation axially bored line extended line.It is connected in locking hole
There is lock-screw 6, lock-screw is closely connected on scribing line column outer wall.Locking hole is arranged on pedestal front and rear sides, adjacent two lock
Tieholen one is arranged on pedestal leading flank, another is arranged on pedestal trailing flank.Pedestal lower surface is equipped with sliding slot 7, sliding
Be slidably mounted in slot two for cover conjunction mounting hole slide plate 8, two slide plates are symmetrical set, sliding slot two side outer edge position
The positive stop strip 9 being equipped with for limit skateboard is put, two slide plate opposite ends are equipped with the driving lever 10 of L-shaped, and two driving levers are oppositely arranged.
The testing requirements of the distance between pedestal upper installing hole coupon are previously set, and coupon detection is drawn lattice tool and used
When, pedestal is held, lattice are drawn by scribe head towards coupon and on coupon surface, without with reference to graduated scale, easy to operate, scribing line
Precisely, it is not likely to produce error.Column of crossing carries out locking positioning by lock-screw, and connection positioning is reliable.
Embodiment described above is a kind of preferable scheme of the utility model, not the utility model is made any
Formal limitation also has other variants and remodeling under the premise of without departing from the technical solution recorded in claim.
