To achieve these goals, the utility model adopts following technical scheme:
This weld-fusion line impact specimen breach locating device, comprise back up pad, the folder chi, setscrew nut, gland nut, wherein said back up pad two ends have positioning baffle and supporting baffle respectively, the positioning baffle lateral surface has vertical rule, the folder chi is by being positioned at back up pad top along the located lateral chi with horizontal scale mark of back up pad horizontal expansion be positioned at the positioning baffle outside and constitute along the vertical vertical positioning rule of extending of positioning baffle, position corresponding to positioning baffle on the located lateral chi has positioning spiro pit, the setscrew nut spiral shell is set in the threaded hole of position, laterally have the collet threaded hole on the supporting baffle, gland nut is arranged in the collet threaded hole, has the guide mechanism that makes folder chi vertical slide guide on back up pad between positioning baffle and vertical positioning rule.
Described guide mechanism is cooperatively interacted with the projection piece that is positioned at vertical positioning rule lower end by the rule groove that is positioned at the positioning baffle bottom and constitutes.
Described slide guide structure also can be cooperatively interacted with the rule groove that is positioned at vertical positioning rule lower end by the projection piece that is positioned at the positioning baffle bottom and constitute.
In order to make sample stress balance when clamping, describedly on supporting baffle, laterally have two collet threaded holes, gland nut has has two to be arranged in respectively in two collet threaded holes.
In order further to make sample stress balance when clamping, the termination of described two gland nuts is connected with the pressure strip of longitudinal extension jointly.
Described positioning baffle two ends extend lengthwise into outside the back up pad.
Described pressure strip two ends extend lengthwise into outside the back up pad.
The weld-fusion line impact specimen breach locating device that said structure has been arranged, in the weld-fusion line impulse test, just can be placed in many samples on the back up pad simultaneously, and welding melt run gap position is accurately located by utilizing the folder chi and the location of setscrew nut and the nut of pressing on to the border to compress apace, reach and reduce sample location workload, accelerate the test period, reduce personal error, guarantee that sample locatees accurate effect.
