The screw used to fixing the nut in a matched manner is common, processing is simple, other components and the screws are mutually independent components; the screws can be easily replaced after being damaged and are low in cost; and by virtue of replacing the screw, the nut drawing force test structure can adapt to the test of nuts with different diameters and is wider in application range.
Description
[technical field]
The present invention relates to a kind of nut drawing force test structure, particularly relate to a kind of nut drawing force test structure.
[background technology]
In the time that production has the product of nut, conventionally can carry out the pulling capacity test of nut, to detect the firm degree of nut.
Currently used test structure refers to Fig. 1, and Fig. 1 illustrates the nut drawing force test structure schematic diagram into prior art, and described structure has pull bar 100, and its one end has drawing hole 101, and the other end has test screw 102.
Incorporated by reference to consulting Fig. 2, Fig. 2 illustrates the nut drawing force test structure application schematic diagram into prior art.Described test screw 102 is fixed on to the nut 104 of product 103,101 one end, described drawing hole are hooked and are carried out pulling capacity test by spring balance 105.
But, adopt said structure can there is following shortcoming, when described nut 104 diameters hour, described test screw 102 corresponds to small diameter, described test screw 102 processing difficulties (are for example worked as for below M2.5, also be that diameter is while being less than 2.5mm), and easy loss in the time of test, because described structure is structure as a whole, after damaging, cost of idleness is high, and described structure is and described nut 104 models structure one to one, therefore can not one multiplex, bad adaptability.
In view of this, be necessary to develop a kind of nut drawing force test structure in fact, to address the above problem.
[summary of the invention]
Therefore, the object of this invention is to provide a kind of nut drawing force test structure, solve existing structure processing difficulties, fragile, and damage cost high, apply single problem.
In order to achieve the above object, nut drawing force test structure provided by the invention, this structure comprises:
Pull bar, its one end has drawing hole;
Be connected and fixed bar, described pull bar is fixed on away from one end, described drawing hole in its one end, described in be connected and fixed and on bar, there is external thread;
Abutment sleeve, its one end has the internal thread extending in it, described in described screw-internal thread fit is fixing, is connected and fixed the described external thread on bar, and the described abutment sleeve other end has hanging platform;
Screw, it has thread and screw terminal, and described screw is located in described abutment sleeve, and described thread has hanging platform one end by described abutment sleeve and exposes, and described screw terminal is limited to described hanging platform, and described thread coordinates with described nut shape.
Optionally, described pull bar has fixing internal thread away from one end, described drawing hole, is fixed with the described external thread that is connected and fixed bar.
Optionally, described pull bar with described in be connected and fixed the structure that bar is formed in one.
Optionally, described pull bar is radially offered and penetrated in described drawing hole along described pull bar.
Optionally, the thread diameter of described screw is less than 2.5 millimeters.
Compared to prior art, utilize nut drawing force test structure of the present invention, in the time using, described screw is inserted in described abutment sleeve, again will described in be connected and fixed the fixing described pull bar in bar one end, the other end screws in described abutment sleeve, make described screw compacted, and the screw terminal of described screw is stopped by described hanging platform, described thread is exposed by described abutment sleeve, again described thread is fixed on to described nut, application of force drawing is carried out in described drawing hole to described pull bar, and then reaches the object of pull-out test.Owing to being conventional screw for what be fixed with described nut, therefore processing is simple, and other element and described screw are separate element, therefore described screw is easily changed after damaging, cost is low, owing to can reaching by changing described screw the test of the nut that is applied to different-diameter, therefore range of application is wider again.
