Abstract
The invention relates to a projection-welding shaft-type component welding-strength nondestructive detection tool. The projection-welding shaft-type component welding-strength nondestructive detection tool comprises a rod body and a central hole which is formed in the bottom of the rod body in the axial direction, wherein the lower end of the rod body is of an inverted circular truncated cone structure. When the detection tool is in use, the rod body sleeves a shaft-type component or a double-screw bolt by virtue of the central hole, the bottom plane of the rod body contacts the surface of a workpiece, and the rod body stays at a vertical state; then the rod body is driven to be bent, the rod body is bent until the conical surface contacts the surface of the workpiece, the bending of the rod body is stopped, the bending angle of the shaft-type component or double-screw bolt already reaches A degrees, if the cylindrical shaft-type component or double-screw bolt is dropped on the welding position, the welding strength is unqualified, and the welding parameter needs to be adjusted; if the cylindrical shaft-type component or the double-screw bolt is not dropped on the welding position, the welding strength is qualified, then the rod body is pulled in an opposite direction until the bottom plane contacts the surface of the tool again, the rod body is stopped bending, the workpiece is restored to an original shape, and the online nondestructive detection of the welding strength of the cylindrical shaft-type component or double-screw bolt is ended.
Description
Technical field
The present invention relates to a kind of projection welding welding shaft part intensity nondestructive inspection instrument.
Background technology
Need to carry out nondestructive test to weld strength online after projection welding cylinder axial workpiece or stud above white skin pilothouse; supervisory personnel utilizes hand hammer to knock cylinder axial workpiece or stud (need protect screw thread) from left and right two each and every one directions to deformation tilt 10 °-30 °; as coming off does not appear in projection welding place, then projection welding is qualified.Knock again after inspection terminates and part is restored to the original state.Not only waste time and energy in whole inspection operating process, and angle is difficult to grasp, and knocks also easy defective work piece and screw thread.
Summary of the invention
The present invention, in order to overcome the deficiency of above technology, provides a kind of projection welding welding shaft part intensity nondestructive inspection instrument operating facility, do not destroy workpiece.
The present invention overcomes the technical scheme that its technical matters adopts:
A kind of projection welding welding shaft part intensity nondestructive inspection instrument, comprise: the body of rod and be axially set in the center pit bottom it along the body of rod, the lower end of the described body of rod is rounding frustum structure, the baseplane of the described body of rod and the axis perpendicular of center pit, angle between described baseplane and the circular conical surface of the frustum of a cone is A, described A is 10 °-30 °, and the degree of depth of described center pit is greater than the length of the axial workpiece be welded on workpiece, and the external diameter of its aperture and axial workpiece matches.。
In order to improve comfort, the head end of the above-mentioned body of rod makes decorative pattern handle by annular knurl.
The invention has the beneficial effects as follows: be enclosed within axial workpiece or stud by center pit by the body of rod, and baseplane is contacted with the surface of workpiece, now the body of rod is vertical state.Then drive the body of rod to bend, when bending to circular conical surface and contacting with workpiece face, stop bending, now the angle of bend of axial workpiece or stud reaches A °, now as coming off appears in cylinder axial workpiece or stud welding place, then think that weld strength is defective, need welding parameter be adjusted; As do not occurred coming off, then weld strength is qualified.Then oppositely pull the body of rod, until when baseplane contacts with tool-face again, stop bending, now workpiece restores to the original state, and cylinder axial workpiece or the online nondestructive inspection of stud welding intensity terminate.It is high that this instruments of inspection has efficiency, and speed is fast, good reliability, and structure is simple, the easy to use and not advantage such as damage and failure workpiece and screw thread.
Accompanying drawing explanation

Fig. 2 is using state structural representation of the present invention;
Fig. 3 is center pit position of the present invention structure for amplifying schematic diagram;
In figure, 1. workpiece 2. axial workpiece 3. body of rod 4. decorative pattern handle 5. center pit 6. circular conical surface 7. baseplane.
Embodiment
Below in conjunction with accompanying drawing 1, accompanying drawing 2, the present invention will be further described for accompanying drawing 3.
A kind of projection welding welding shaft part intensity nondestructive inspection instrument, comprise: the body of rod 3 and be axially set in the center pit 5 bottom it along the body of rod 3, the lower end of the body of rod 3 is rounding frustum structure, the baseplane 7 of the body of rod 3 and the axis perpendicular of center pit 5, angle between the circular conical surface 6 of baseplane 7 and the frustum of a cone is A, A is 10 °-30 °, and the degree of depth of center pit 5 is greater than the length of the axial workpiece 2 be welded on workpiece 1, and the external diameter of its aperture and axial workpiece 2 matches.Be enclosed within axial workpiece 2 or stud by center pit 5 by the body of rod 3 during use, and baseplane 6 is contacted with the surface of workpiece 1, now the body of rod 3 is in vertical state.Then drive the body of rod 3 to bend, when bending to circular conical surface 6 and contacting with workpiece face, stop bending, now the angle of bend of axial workpiece 2 or stud reaches A °, now as coming off appears in cylinder axial workpiece 2 or stud welding place, then think that weld strength is defective, need welding parameter be adjusted; As do not occurred coming off, then weld strength is qualified.Then oppositely pull the body of rod 3, until when baseplane 7 contacts with tool-face again, stop bending, now workpiece 1 restores to the original state, and cylinder axial workpiece 2 or the online nondestructive inspection of stud welding intensity terminate.It is high that this instruments of inspection has efficiency, and speed is fast, good reliability, and structure is simple, the easy to use and not advantage such as damage and failure workpiece and screw thread.
The head end of the body of rod 3 makes decorative pattern handle 4 by annular knurl.Forming decorative pattern by annular knurl, the friction force with operator can be increased when operating, improve the comfort level and reliability that use.
