Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in more detail.
With reference to Fig. 1, Fig. 3, Fig. 6, a kind of fixture for project-welding nut 5 pressure tests comprises:
The first fixture, comprises the first cylinder 12 and the second cylinder 13 that axial line is located along the same line,Described the second cylinder 13 is inserted in the centre bore 31 of described press base 3;
The second fixture, comprises the first relative end face 21 and the second end face 22, on wherein said the first end faceThe first hole 211 is set, the second hole 221 is set on described the second end face; Wherein said the first cylinder plugsIn described the first hole 211; The project-welding nut 5 of tightening with bolt 4 is set in described the second hole 221, withThe test piece for welding 6 that described project-welding nut 5 welds is mutually positioned on described the second end face. The setting of this structureMake project-welding nut 5 pressure tests very convenient, do not need to find again identical two of specification temporarily and put downPlatform comes, and can reuse. In the time that needs carry out pressure test to project-welding nut 5, first by secondCylinder 13 is inserted and is built in the centre bore 31 of press base 3, and the first cylinder 12 plugs into the second folderThe first hole 211 of tool; The second hole 221 diameters of the second fixture and the size of project-welding nut 5 match, willThe project-welding nut 5 of tightening with bolt 4 is placed in second hole 221 of matching with its size, with projection welding spiral shellFemale 56 of tests piece for welding that weld are mutually placed on the second end face 22 automatically, and can ensure welding examinationIt is identical that plate 6 two ends are placed on length on the second end face 22, so just can ensure project-welding nut 5 and welderingThe pad that connects test plate (panel) 6 is stressed evenly. After put well the position of project-welding nut 5, protruding according to different sizeThe load of the dimension that weldering nut 5 should bear is carried out static load pressure test to bolt 4, if beatThe pad of the project-welding nut 5 of tightening with bolt 4 afterwards is not separated with test piece for welding 6, shows projection welding spiral shellFemale 5 welding quality is qualified.
With reference to Fig. 1 and Fig. 2, the first fixture also comprises a connector 11, the first cylinders 12 and secondCylinder 13 is separately positioned in the both ends of the surface of connector 11 opposing parallel, and connector 11 is shaped as cylinderBody, the diameter diameter of connector 11 is greater than the first cylinder 12 and cylindrical diameter, the first cylinder12 is identical with the diameter of the second cylinder 13. Cylindrical connector 11 is in order to make the second cylinder 13While cooperation with press base 3 centre bores 31, the end face of connector 11 can be fitted in press base 3 stablyEnd face on.
With reference to Fig. 3 and Fig. 4, the second fixture 2 is formed as cylindrical structure, the first end face 21 and the second endThe diameter of face 22 is identical, being centered close on same straight line of the first hole 211 and the second hole 221. The first hole211 and the center line in the second hole 221 be positioned at same plane and can ensure bolt 4 carrying out the survey of static load pressureWhen examination can there is not double swerve in fixture, the stationarity while ensureing static load pressure test.
With reference to Fig. 5, Fig. 6 and Fig. 7, before project-welding nut is carried out to pressure test, first will be to fixtureAssemble, press base 3 lies on horizontal plane, and the first cylinder 13 is inserted on press base 3Centre bore 31 in, now the end face of connector 11 just with the end face laminating of press base 3, then willThe second cylinder 12 inserts in the first hole 211, and the housing of the second fixture is just placed on connector 11.After fixture installation, by the project-welding nut 5 that welds with test piece for welding 6 and tighten with bolt 4In the second hole 221 being inserted on the second fixture, match with project-welding nut 5 sizes, due to test piece for weldingThe diameter in Length Ratio the second hole 221 of 6 is large, and test piece for welding 6 two ends are just set up in the second fixture uniformlyOn housing. According to national standard relevant regulations, the welded nut 5 of different size at least should bear and sizeThe lowest load of the specification that matches, the welding quality that just can show this welded nut 5 is qualified. For example,The project-welding nut 5 that is M4 for a diameter of thread, its solder joint should bear the load that is greater than 1.3KN,Can illustrate that its welding quality is qualified, now press carries out the survey of static load pressure with the dead load of 1.3KN to bolt 4Examination, if after static load pressure test, the entirety that the project-welding nut 5 that bolt 4 is tightened forms is not to the second holeIn 221, moving down, is also that the pad of project-welding nut and test piece for welding does not depart from, and shows that the diameter of thread isThe welding quality of the project-welding nut of M4 is qualified.
Because the above is preferred embodiment of the present utility model, it should be pointed out that for the artThose of ordinary skill, do not departing under the prerequisite of principle described in the utility model, if can also makeDry improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
