Accompanying drawing explanation
Fig. 1 is the structural representation of non-destructive detecting device of the present utility model.
Embodiment
In order to understand the technical solution of the utility model better, be also described in detail by reference to the accompanying drawings below by specific embodiment.
Refer to Fig. 1, embodiment of the present utility model, a non-destructive detecting device for the weld strength of project-welding nut on auto parts, the three groups of testing agencies comprising worktable 1, be arranged on the cylinder clamping mechanism 2 of the front portion of the table top 11 of worktable and be laterally disposed side by side on above worktable 1.The below of the table top 11 of worktable 1 is provided with table base 12, and table base 12 is in rectangular parallelepiped tower structure.
Mei Zu testing agency includes support 3, scale bar 4, load 5 and register pin 6.Support 3 comprises vertical rod 31, first vertical pole 32 and the second vertical pole 33, the bottom of vertical rod 31 is fixed on the rear portion of the table top 11 of worktable 1, and vertical rod 31 is positioned at the rear of cylinder clamping mechanism 2, the rear end of the first vertical pole 32 is fixed on the top of vertical rod 31, the rear end of the second vertical pole 33 is fixed on the middle and lower part of vertical rod 31, and vertical rod 31, first vertical pole 32 and the second vertical pole 33 surround F shape structure; Scale bar 4 is vertically set between the first vertical pole 32 and the second vertical pole 33; Load 5 is cylindrical, this load 5 is offered the through hole of a up/down perforation, and load 5 be can slide up and down by this through hole and is socketed on scale bar 4; Register pin 6 is fixed on the bottom of scale bar 5, and this register pin 5 is suspended in directly over described cylinder clamping mechanism.
On a kind of auto parts of the present utility model, the course of work of the non-destructive detecting device of the weld strength of project-welding nut is:
