Technical field
The utility model relates to a kind of clamping device, and is particularly a kind of when bolt is carried out tension test, is used for the device of grip bolt, belongs to material mechanical performance test unit technical field.
Background technology
The mechanical properties such as the tensile strength of bolt are closely related with factors such as the material of bolt, screw processing qualities, directly affect the safety of the use occasions such as wind-force pylon, electric tower.Because the anchor clamps of current material testing machine can not satisfy the requirement of all bolt tension tests, are difficult to the mechanical properties such as tensile strength of bolt are accurately detected.Therefore, be necessary prior art is improved.
Summary of the invention
The purpose of this utility model is to provide a kind of bolt tension test to use clamping device, and the bolt that is applicable to the clamping plurality of specifications carries out tension test.
Concrete scheme is:
A kind of bolt tension test clamping device, it is characterized in that by the pull bar matched with the upper anchor clamps of Material Testing Machine, on its that links to each other with pull bar with the upper flange of through hole, on its that links to each other with upper flange by coupling bolt and nut with the lower flange of through hole, be movably placed on the lower flange through hole its cushion block with through hole, pass the cushion block through hole with the tested bolt of nut and stretch out with the lower clamp of Material Testing Machine matched downwards.
Described upper and lower flange is disk, its center and periphery all have through hole, wherein, it is matched that the pull bar of its lower end band plug passes the upper anchor clamps of the through hole of upper flange center and Material Testing Machine from bottom to top, coupling bolt and nut place through hole corresponding to upper and lower flange periphery, in order to adjust upper and lower flange position and fixing by coupling bolt and nut.
The through hole of described upper and lower flange periphery is established three at least, and coupling bolt and nut correspondence are made as three, with fixing upper and lower flange.
Described cushion block comprises the cylinder that places in the through hole of lower flange center, block is established in the cylinder upper end, longitudinal hole is established in the block center of cylinder and upper end thereof, tested bolt passes this longitudinal hole from bottom to top and protrudes upward with nut and be connected, and the lower clamp of tested bolt lower end and Material Testing Machine is matched.
Described cushion block arranges a plurality of, each cushion block cylinder external diameter is identical, be movably placed in the through hole of lower flange center, the aperture of the longitudinal hole of cushion block center is made as respectively large aperture, mesoporous, small-bore, with the tested bolt according to different-diameter, select different cushion blocks, finish tension test.
The utlity model has following advantages and effect: adopt such scheme, in the situation that do not change the testing machine agent structure, according to the specification of tested bolt, change corresponding with it cushion block, can carry out easily tension test, be applicable to the tension test of all size bolt, have simple in structure, easy and simple to handle, high efficiency, the advantages such as cost is low, and is practical.
