Sample so that sample is set on pin rod 3, and chuck body 1 is fixed on tensile testing machine finally by connecting rod 13, and carries out
Stretching detection work.
However, yet with sample when carrying out tension test, often there is deformation at sample pin-and-hole, draw and slit among pin-and-hole
And phenomena such as sample head edge fracture, cause to detect test failure, influence the result of detection.
Utility model content
The purpose of this utility model is to provide a kind of sheet clamp, its advantage be clamping sample when, increase sample by
Power area so that the pulling force that sample is born when being stretched is not concentrated in position weaker on through hole, avoids logical
Hole weak location deforms, draws the situation slitted or be broken.
Above-mentioned technical purpose of the present utility model technical scheme is that：A kind of sheet clamp, bag
Jig main body and pin are included, offers the storage tank for placing sample to be checked on jig main body, in the side wall of storage tank both sides
The interspersed pin-and-hole of supply and marketing nail is offered, the connecting rod for being fixed with tensile testing machine, pin are provided with above jig main body
Fastening bolt and pin cylinder, sample including threaded connection are set in fastening bolt in storage tank, and sample one end and pin cylinder
Tightly abut, the other end tightly abuts with storage tank inwall.
By using above-mentioned technical proposal so that weaker position is acted on by chucking power on sample, will stretch
When the power that is subject to arrived by the pin cylinder and storage tank side-wall dispersion for being clamped in its both sides on the surface of sample, avoid weak position
Put caused deformation, draw the problems such as slitting or being broken.
Preferably, the pin cylinder is towards being provided with non-slip texture on the outer surface of one end of sample.
By using above-mentioned technical proposal, the position that pin cylinder abuts with sample has very big frictional force, and sample holder exists
When selling in cylinder and accommodating groove sidewall, the phenomenon that will not skid.
Preferably, being arranged with packing ring in the fastening bolt, packing ring is between pin cylinder and sample, the thickness of packing ring radial direction
More than the wall thickness of pin cylinder.
By using above-mentioned technical proposal, packing ring further increases the lifting surface area of sample, for weaker on sample
Position can preferably be protected, avoid producing fracture etc. unexpected.
Preferably, it is provided with non-slip texture on the outer surface of the packing ring both sides.
By using above-mentioned technical proposal, packing ring both ends are respectively provided with bigger friction with the position that pin cylinder and sample abut
Power so that sample and packing ring stably can be arranged in fastening bolt, further avoid the phenomenon for producing and skidding.
Preferably, one end of the anti-skid washer towards sample is installed with cushion rubber.
By using above-mentioned technical proposal, cushion rubber can produce certain deformation after stress so that sample is clamped
The area of power is further increased.
Preferably, it is in inverted T shaped stopper slot that the chuck body upper end, which offers section, the connecting rod is embedded described
In stopper slot, and with stopper slot shape adaptation.
, can be to chuck body after chuck body is fixed on tensile testing machine by using above-mentioned technical proposal
It is finely adjusted, ensures that the sample between two chuck bodies up and down is lasting vertical state.
Preferably, the connecting rod free end is provided with screw thread.
By using above-mentioned technical proposal, bigger frictional force is had between connecting rod and tensile testing machine so that connection
Bar more can be stably fixed in tensile testing machine, will not be fallen off in tension test.
In summary, the utility model has the advantages that：
1. the pulling force that sample is subject to is dispersed on the surface of sample so that weaker position will not produce disconnected on sample
The fortuitous event such as split；
2. by increasing the frictional force between sample and fixture so that be not in during sample is fixed
The situation of skidding；
, will not be in the process of stretching 3. chuck body is fixed in tensile testing machine by what connecting rod can be consolidated more
In fall off so that detection work can be smoothed out.
