Description
Technical field
The present invention relates to a kind of stud welding pick-up unit and detection method thereof, especially relate to a kind of stud welding fixture guide sleeve detector and detection method thereof.
Background technology
At present, in the welding technology of automobile making, arc stud welding obtains widespread usage.Its application is also just at expanded scope, and its welding quality will directly influence the assembly quality of general assembly assembling.On the one hand; If deviation takes place in the position of welding or the double-screw bolt deflection will cause assembly parts to be difficult to pack into; Also extra-stress can be produced even pack into, after product uses a period of time through the user, a series of problems such as the loosening or assembly parts distortion of double-screw bolt will be caused after its stress relief.On the other hand, if the insufficient strength of stud welding causes general assembly assembling process double-screw bolt to break so probably, bring a large amount of problems of doing over again thus.The problem of this two aspect all can influence complete vehicle quality.This shows that the welding quality of arc stud welding is extremely important.Double-screw bolt is a key factor that influences welding quality to the verticality of workpiece face of weld, and Fig. 1 and Fig. 2 are seen in its influence.Cause the reason of double-screw bolt deflection to have two: the one, stud clip deflection in the welding gun; The 2nd, fixture guide sleeve deflection (guide pin bushing center line and workpiece face of weld out of plumb).The stud clip deflection can be safeguarded through daily welding gun and guarantee, but the fixture guide sleeve deflection can only be leaned on visual detection, and very difficult assurance double-screw bolt is vertical to workpiece.
Summary of the invention
The present invention has designed a kind of stud welding fixture guide sleeve detector and detection method thereof; The technical matters of its solution provides the stud welding fixture guide sleeve pick-up unit of the easy and easy operating of a cover, and its purpose is that convenient and reliable ground detects the verticality of stud welding fixture guide sleeve to the workpiece face of weld.
In order to solve the technical matters of above-mentioned existence, the present invention has adopted following scheme:
A kind of stud welding fixture guide sleeve detector comprises detector fixed cover and dial gauge, and said dial gauge is fixed on the said detector fixed cover through stationary installation; When using said stud welding fixture guide sleeve detector, the contact pilotage and the bond pad locations of said dial gauge come in contact.
Further, said stationary installation is interior hexagonal holding screw.
Further, said detector fixed cover stand on the face of weld through the leg more than three.
A kind of detection method of using stud welding fixture guide sleeve detector may further comprise the steps:
4.1 check said stud welding fixture guide sleeve detector, confirm that it is in good condition;
4.2 confirm bond pad locations, then the contact pilotage of dial gauge is aimed at bond pad locations, and the leg of detector fixed cover contacted with face of weld align;
4.3 the adjusting dial gauge makes pointer point to 0 scale;
4.4, be put into stud welding fixture guide sleeve detector fixture guide sleeve the inside and press, observe the sensing scale of said dial gauge pointer, if between pointed-1.5 degree to+1.5 degree time then the fixture guide sleeve welding is qualified with clamp; The welding of said fixture guide sleeve is not defective if pointer does not point between above-mentioned scale area.
Further, said pointed is 0 when spending, and said fixture guide sleeve welding effect is best.
This stud welding fixture guide sleeve detector and detection method thereof have following beneficial effect: the present invention combines through a detector fixed cover and dial gauge; Break through former dial gauge and only be used for detecting the usable range that the little shift length of workpiece shaped position sum of errors is measured; Through it measured value is converted into angle value, it is used to detect the verticality of stud welding gun fixture guide sleeve.

Embodiment
Below in conjunction with Fig. 3 to Fig. 7, the present invention is further specified:
A kind of stud welding fixture guide sleeve detector comprises detector fixed cover 1 and dial gauge 2, and said dial gauge 2 is fixed on the said detector fixed cover 1 through stationary installation; When using said stud welding fixture guide sleeve detector, the contact pilotage 22 and the bond pad locations 6 of said dial gauge 2 come in contact.Detector fixed cover 1 is that the arc-extinguish chamber transformation according to the stud welding machine welding gun forms; Compact conformation, make simple, easy to use, with low cost; Can well simulated welding gun, so this stud welding fixture guide sleeve detector can detect the fixture guide sleeve of each position.
Said stationary installation is interior hexagonal holding screw 3.
Said detector fixed cover 1 stand on the face of weld 5 through the leg more than three 7.As shown in Figure 3, the quantity of said leg 7 is four.
A kind of detection method of using stud welding fixture guide sleeve detector may further comprise the steps:
4.1 check said stud welding fixture guide sleeve detector, confirm that it is in good condition;
4.2 confirm bond pad locations 6, then the contact pilotage 22 of dial gauge 2 is aimed at bond pad locations 6, and the leg 7 of detector fixed cover 1 contacted with face of weld 5 align;
4.3 regulate dial gauge 2, make pointer 21 point to 0 scale;
4.4, be put into stud welding fixture guide sleeve detector fixture guide sleeve 4 the insides and press, observe the sensing scale of said dial gauge 2 pointers 21, if when pointer 21 points between-1.5 degree to+1.5 degree then fixture guide sleeve 4 welding are qualified with clamp; 4 welding of said fixture guide sleeve are not defective if pointer 21 does not point between above-mentioned scale area.
Said pointer 21 is oriented to 0 when spending, and said fixture guide sleeve 4 welding effects are best.
This stud welding fixture guide sleeve detector and detection method principle of work thereof are following:
This detector is mainly used in and detects fixture guide sleeve 4 and face of weld 5 angulations, is used for fixture guide sleeve 4 and laterally arranges with contact pilotage 22, so contact pilotage 22 promptly is fixture guide sleeve 4 and face of weld 5 angulations with face of weld 5 angulations.When contact pilotage 22 and face of weld 5 angulations at 88.5 ° between 91.5 ° the time, explain that then fixture guide sleeve 4 welding are qualified, if contact pilotage 22 and face of weld 5 angulations are 90 when spending, welding effect is best.
As shown in Figure 6, dial gauge 2 length that contact pilotage 22 does not stretch out detector fixed cover 1 under the duty is L;
Detector is under the duty in the accompanying drawing 7, and ∠ C=90 °, the dial gauge reading is X; CB is used to push the residue length of post shrinkage for the dial gauge contact pilotage, and detector fixed cover tip radii is AC=R;
From the above, CB=L-X, tan ∠ A=CB/AC,
∠B＝90°-∠A＝90°-arctan(CB/AC)＝90°-arctan【(L-X)/R】。
When the angle that calculates as ∠ B was 90 °, the dial gauge reading was that X will be shown as 0;
When the angle that calculates as ∠ B is 88.5 ° to 91.5 °, the dial gauge reading be X also will+1.5 ° demonstration in the intervals.
