Background technology
Project-welding nut is mainly used for the stamping parts of welding low-carbon steel and low-alloy steel.In parts industry, projection welding
Connecting mode has the advantages of many：Multiple solder joints can be welded simultaneously in a weld cycle.Not only productivity is high, but also does not have
Shunt influence.Therefore can be arranged on narrow position solder joint without receptor site away from limitation.Since current density combines in salient point, electricity
Current density is big, therefore can be welded with smaller electric current, and can be reliably formed smaller nugget.In spot welding, corresponding Mr. Yu
One thickness of slab, the nugget that formed less than a certain size are highly difficult.The position of salient point is accurate, size is consistent, the intensity of each point
Than more uniform.Therefore spot welding can be less than for given intensity, the size of projection welding spot.Due to using big plane electrode, and
Salient point is set on an object, so can mitigate the impression on another workpiece exposed surface to greatest extent.Big plane simultaneously
The current density of electrode is small, good heat dissipation, and the abrasion of electrode is more much smaller than spot welding, thus greatly reduces maintenance and the dimension of electrode
Repair expense.Compared with spot welding, the influence of the oil, rust, oxide skin, coating and other coatings of workpiece surface to projection welding is smaller, but dry

3’；Operator's hand holds product 1 ' when welding slag detects, and is screwed into thread measurement go-no go gauge 2 ' in project-welding nut screw thread, screws in screw thread
3-5 circle detections, without welding slag if it can be screwed into product, otherwise there is welding slag；Operator examines spot welding intensity during spot welding intensity detection
It surveys block 3 ' to be screwed into product 1 ' and fasten motionless, is integrally put into universal strength tester and carries out the test of spot welding strength failure,
Judge whether spot welding intensity is qualified by calculating average value.But both approaches are required for manual operation, and the product is
During full inspection, relatively complicated, operator's labor is operated to screw thread welding slag and the realization of spot welding intensity one by one for large quantities of mass productions
Fatigue resistance is big, is affected by artificial subjective factor, and structural stability is poor；Moreover, when being threaded into go-no go gauge, beat is acted
Time can not shorten, and cause whole production efficiency more relatively low.
In order to realize project-welding nut automatic detection, it is necessary to provide a kind of step pitch material selection mechanism, there is lifting and translation
Function, so as to realize the step pitch feeding of project-welding nut automatically.
