In automobile manufacturing process, in it, the nut of each parts needed to confirm the position of nut before being welded and fixed, and then welded again. Whether prior art senses, typically by photoelectric sensor, the position that nut places correct, in actual mechanical process, owing to the reason photoelectric sensors such as space have certain distance apart from part nut to be detected, easily make photoelectric sensor sensing lose efficacy, the unfavorable condition not having nut can also carry out follow-up welding occurs.
Summary of the invention
In view of the defect that above-mentioned prior art exists, the purpose of the present invention is to propose to a kind of automobile nut-welding leakage proof detection device, it is ensured that the reliability of induction apparatus sensing. The purpose of the present invention will be achieved by the following technical programs:
One automobile nut-welding leakage proof detection device of the present invention, including a cuboid pedestal, in described pedestal both sides, symmetrical being provided with regulates pad and block, described adjustment pad is clamped and is fixed on pedestal sidewall by described block, make the bottom of block beyond base bottom, in described pedestal, vertical direction offers through hole, the upper end closing in of described through hole makes the aperture less than other positions, the aperture of upper port, groove is offered at described through-hole wall, it is equiped with alignment pin in described through hole, bossing on described alignment pin sidewall stretches to described groove, make described alignment pin can only move up and down at the altitude range of described groove, the upper end of described alignment pin is provided with a spring, the external diameter of described spring is more than the aperture of described through hole upper port, the upper end making spring is against upper end closing in place of through hole, described pedestal top is provided with the fixing seat being fixed as one, it offers hole, location, sensor is vertically fixed on above pedestal through hole, described location by screw, make sensor lower end inductive head corresponding with the upper port of described through hole.
Further, described alignment pin is step pin to the present invention, and its lower end diameter is less than upper end diameter.
The present invention further, in described pedestal, described through hole be provided around Magnet, make described alignment pin contact described Magnet and there is magnetic.
The beneficial effects are mainly as follows: by the appropriate design of the present invention, make induction apparatus can detect on job position whether have nut accurately, add the reliability of induction apparatus sensing, be smoothed out in weld job after being conducive to, improve production efficiency.
Hereinafter just accompanying drawing in conjunction with the embodiments, is described in further detail the specific embodiment of the present invention, so that technical solution of the present invention is more readily understood, grasps.
Accompanying drawing explanation
Fig. 1 is the structural representation of the preferred embodiment of the present invention;
Fig. 2 is the partial structurtes sectional view of the preferred embodiment of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be described with specific embodiment, for embodiment be only product of the present invention or method are made generality illustrate, contribute to being more fully understood that the present invention, but be not limiting upon the scope of the invention.
As depicted in figs. 1 and 2, automobile nut-welding leakage proof detection device of the present invention, including a cuboid pedestal 1, in described pedestal 1 both sides, symmetrical being provided with regulates pad 2 and block 3, described adjustment pad 2 is clamped and is fixed on pedestal 1 sidewall by described block 3, makes the bottom of block 3 exceed bottom pedestal 1, in convenient working process, the bottom of block 3 fixes in the locating slot of job position, thus being accurately positioned the detection position of the present invention.
In described pedestal 1, vertical direction offers through hole, the upper end closing in of described through hole makes the aperture less than other positions, the aperture of upper port, groove 8 is offered at described through-hole wall, alignment pin 7 it is equiped with in described through hole, bossing on described alignment pin 7 sidewall stretches to described groove 8, make described alignment pin 7 can only move up and down at the altitude range of described groove 8, the upper end of described alignment pin 7 is provided with a spring 6, the external diameter of described spring 6 is more than the aperture of described through hole upper port, the upper end making spring 6 is against upper end closing in place of through hole, will not close up from the upper end of through hole and eject. specifically, described alignment pin 7 is step pin, and its lower end diameter is less than upper end diameter.
In addition, it is additionally provided with the fixing seat 4 being fixed as one on described pedestal 1 top, this fixing seat 4 plays the effect supported with stationary induction apparatus 5, by the hole, location 9 offered on fixing seat 4, screw is coordinated vertically to be fixed on above pedestal 1 through hole, described location 9 by sensor 5, make sensor 5 lower end inductive head corresponding with the upper port of described through hole, when making sensor 5 work, its lower end inductive head can detect the upper end position of described alignment pin 7 through the upper end open of described through hole, judge that part nut 8 to be detected is whether on default job position by the position of follow-up test to alignment pin 7. finally, in described pedestal 1, described through hole be provided around Magnet, make described alignment pin 7 contact described Magnet and have magnetic.
The work process of the present invention is briefly described below.
When part nut to be detected is placed on default job position accordingly, before welding, by linking the top position that apparatus of the present invention are sent to part nut to be detected by the actuating device of the present invention, induction apparatus 5 is energized in running order, nut aperture to be detected is slightly larger than the lower end diameter of used alignment pin 7, owing to this alignment pin 7 is preferably step pin, therefore when operation, if nut to be detected is M6 nut, the hole in piece part position of M6 nut operation is 7, then the lower end of regioselective pin 7 is 5.96, and upper end is 6.9.
The present invention is from top to bottom moved, the bottom of block 3 is fixed in the locating slot of job position, be accurately positioned detection position. Being displaced downwardly in the process of locating slot at above-mentioned block 3, if the position, hole of position to be detected is placed with nut to be welded, then the lower end of alignment pin 7 stretches in nut bore, owing to alignment pin 7 is magnetic, it is to avoid flown on nut top to be detected in its decline process. Afterwards, the upper end of step is stuck in nut upper end, make the upper end compression spring 6 of alignment pin 7, the position of its upper end is moved relative on the position of pedestal 1, makes induction apparatus 5 alignment pin 7 can be detected, then have nut on transmission signal instruction position to be detected, next step weld job can be carried out, after nut-welding completes, apparatus of the present invention are moved, complete one-time detection location.
If leakage is placed in the position, hole of position to be detected has put nut to be welded, the lower end of alignment pin 7 and upper end can the whole hole in piece part positions through nut operation, spring 6 will not be compressed, make induction apparatus 5 alignment pin 7 can not be detected, then transmission signal instruction position to be detected do not have nut, it is impossible to carry out next step weld job.
By the appropriate design of the present invention, make induction apparatus can detect on job position whether have nut accurately, add the reliability of induction apparatus sensing, be smoothed out in weld job after being conducive to, improve production efficiency.
The present invention still has numerous embodiments, all employing equivalents or equivalent transformation and all technical schemes of being formed, all falls within protection scope of the present invention.
