Description
Technical field
A kind of stretching device is the utility model is related to, a kind of specifically a kind of stretching device for verifying Joint Strength.
Background technology
Spot welding is Joining Technology the most frequently used on white body, with the high speed development of Global Auto industry, the weldering of white body
Connect and presentation quality is just becoming more and more important, so verifying the rational reality of welding parameter according to different nugget sizes
Testing becomes essential.
The selection of welding parameter is typically material and thickness according to workpiece, with reference to the welding condition table choosing of this kind of material
Take, it is first determined the end surface shape and size of electrode.Secondly electricity is welded in tentatively selected electrode pressure and weld interval, then regulation
Stream, with different electric current welded specimens, after nugget size meets the requirements on inspection, then electrode pressure is adjusted in appropriate scope
Power, weld interval and electric current, the welding and inspection of sample are carried out, until quality of welding spot complies fully with wanting for technical conditions defined
Untill asking.
The method of the most frequently used test sample is the method for tearing, and the mark of high-quality solder joint is：Tear sample it is a piece of on have
Circular hole, there are circular bosses on another.Slab or quenched materials can not tear out circular hole and boss sometimes, but can pass through the fracture of shearing
Judge the diameter of nugget.If necessary, also need to carry out low power measurement, stretch test and x-ray examination, to judge that penetration rate, shearing resistance are strong
Shrinkage cavity, crackle etc. are spent and whether there is, therefore this kind of method is comparatively laborious.
Utility model content
In view of the above-mentioned problems existing in the prior art, this application provides a kind of stretching device of checking Joint Strength, solution
Artificial experimental verification efficiency of having determined is low, nugget can not be torn moment；Tear the problems such as nugget is not directly perceived.
To achieve the above object, the technical scheme of the application use is：Verify a kind of stretching device of Joint Strength, bag
Include：First mechanism and the second mechanism, first mechanism and the second mechanism are placed on workbench；First mechanism, including：
Cylinder, body I, device for screwing up I, sliding block and track, the cylinder are connected with body I, and device for screwing up is provided with body I
I, sliding block is provided below, the sliding block slides in track；Second mechanism, including：Body II, device for screwing up II, bloom, this
Body II is installed on bloom, and device for screwing up II is located on body II；Hatch frame is equipped with body I and body II, it is described
Hatch frame on body I and the hatch frame on body II are contour.
Preferably, the material of the body I and body II is 45 steel.
Preferably, the cylinder, track, bloom are in contact with workbench.
Preferably, the track both sides are provided with linear mounting hole, for track to be fixed on into workbench.
Preferably, the bloom bottom is provided with mounting hole, for bloom to be fixed on into workbench.
The utility model can obtain following technique effect due to using above technical scheme：Using No. 45 steel hardness
Height, will not produce deformation during test piece welding spot tensile failure because of external force, and the device for screwing up of the first mechanism and the second mechanism is also simultaneously
It ensure that solder joint is destroyed by external force, so as to solve the solder joint discontinuity of manual tension test, brave core destroys imperfect
Phenomenon；It also apparent can intuitively judge solder joint Spot size simultaneously, verify the selection of different thickness of slab Combination Welding conditions.

Embodiment
In order that the purpose of this utility model, technical scheme and advantage are clearer, below in conjunction with the accompanying drawings and it is embodied
The utility model is described in detail example.
Embodiment 1
The present embodiment provides a kind of stretching device of checking Joint Strength, including：First mechanism and the second mechanism, described
One mechanism and the second mechanism are placed on workbench；First mechanism, including：Cylinder, body I, device for screwing up I, sliding block and
Track, the cylinder are connected with body I, and device for screwing up I is provided with body I, and sliding block is provided below, and the sliding block exists
Slided in track；Second mechanism, including：Body II, device for screwing up II, bloom, body II are installed on bloom, device for screwing up II
On body II；Be equipped with hatch frame on body I and body II, the hatch frame on the body I with body II
Hatch frame it is contour.
Preferably, the material of the body I and body II is 45 steel.
Preferably, the track both sides are provided with linear mounting hole, for track to be fixed on into workbench.The bloom
Bottom is provided with mounting hole, for bloom to be fixed on into workbench.
In use, at the hatch frame that solder joint test piece side is put on body I, opposite side is put into the opening on body II
At structure, both sides are tightened respectively using device for screwing up, press switching cylinder, and solder joint will be torn by moment, expose the nugget come
For flash disruption nugget, it can intuitively pass through the reasonability of Spot size checking welding parameter.
It is described above, the only preferable embodiment of the utility model, but the scope of protection of the utility model is not
This is confined to, any one skilled in the art is in the technical scope that the utility model discloses, according to this practicality
New technical scheme and its utility model design are subject to equivalent substitution or change, should all cover in protection model of the present utility model
Within enclosing.
