Detailed description of the invention
Below in conjunction with drawings and Examples, the technical solution of the utility model is described in further detail.
Embodiment
As shown in Figure 1: a kind of stud welding gun being applicable to T-shaped weldering nail that the present embodiment provides, including torch body 1, described torch body 1 includes housing 11, main shaft 12 and is arranged on the drive mechanism (not shown in figure 1) moved up and down in order to the weldering nail clip 13 and drive shaft body of installing weldering nail of main shaft 12 front end；It is symmetrically arranged on two with guide pillar 2 at described housing 11, upper at every side body 11, bottom is provided with guide pin bushing 3, every side guide pillar 2 is located in and is positioned at the upper of homonymy, in lower guide pin bushing 3, and on being positioned at, it is arranged with spring 4 on guide pillar 2 between lower guide pin bushing 3, it is provided with limited block 5 in the lower end of described spring 4 and (adjusting nut can be used, convenient regulation operation), fixing seat 6 it is fixedly connected with in the lower end of both sides guide pillar 2, on described fixing seat 6, weldering nail clip 13 be arranged right below for welding the perforation (not demonstrating in Fig. 1) that nail clip head passes through, bottom at described fixing seat 6, the underface of perforation is fixedly connected with porcelain ring chuck 7.
Shown in Fig. 1 and Fig. 2: described porcelain ring chuck 7 is circumferentially distributed by several flexure strips 71 and is formed, and each flexure strip 71 is L-shaped, by long-armed formed cavity diameter value d of all L-shaped flexure strips 71 more than the maximum outside diameter value welding nail clip 13.The galianconism end of each L-shaped flexure strip 71 is sequentially provided with importing inclined-plane 72, locating surface 73 from bottom to top and derives inclined-plane 74, is forming boss 75 between locating surface 73 and derivation inclined-plane 74.Described importing inclined-plane 72 is inclined upwardly from outside to inside, and described derivation inclined-plane 74 is inclined upwardly from the inside to the outside, and described locating surface 73 is rectangular.Described design can ensure the axiality welding nail clip head and the accurate contraposition of T-shaped weldering ailhead and T-shaped weldering nail with porcelain ring, it is ensured that the concordance of welding quality.
Described stud welding gun is used to realize T-shaped weldering nail as follows with the work process of porcelain ring automatic clamping and disengaging:
First, hand or with robot or triaxial movement platform, the surface of 8 is followed closely in the T-shaped weldering making torch body 1 be moved downwardly to be cased with porcelain ring 9, and when torch body 1 moves downward, spring 4 is compressed (as shown in Figure 3)；
Along with continuing traveling downwardly of torch body 1, the head contact of 8 is followed closely in porcelain ring chuck 7 and T-shaped weldering, and the head of T-shaped weldering nail 8 is tentatively directed at porcelain ring chuck 7 by importing inclined-plane 72, slips into and be clamped in locating surface 73.Owing to locating surface 73 is rectangular, thus can ensure that the axiality between T-shaped weldering nail 8 and porcelain ring chuck 7.Further, since the head of T-shaped weldering nail 8 withstands on the top, right angle of locating surface 73, therefore, porcelain ring chuck 7 now cannot continue to move down and remain stationary as, and spring 4 is further compressed (as shown in Figure 4)；
Now, doing descending motion by drive mechanism drive shaft body 12, make weldering nail clip 13 continue to move downward, until top is pressed on the minor face end face of L-shaped flexure strip 71, during this, spring 4 keeps state shown in Fig. 4 (as shown in Figure 5)；
Continue to make main shaft 12 do descending motion, weldering nail clip 13 is made to continue to press down the minor face end face of L-shaped flexure strip 71, so that the flexure strip 71 constituting porcelain ring chuck 7 is flared out, the head making T-shaped weldering nail 8 enters in weldering nail clip 13, and now torch body 1 obtains the most descending, porcelain ring chuck 7 being contacted with porcelain ring 9, and makes porcelain ring 9 be downwardly into locating surface 73 and position and clamp importing leading of inclined-plane 72, now spring 4 is in the limit state (as shown in Figure 6) compressed；
Make torch body 1 up, carry weldering nail clip 13 to move upward, T-shaped weldering nail 8 is made to be raised, when the bottom of T-shaped weldering nail 8 concordant with bottom porcelain ring 9 (or the distance bottom less than porcelain ring is for welding pre compressed magnitude), now porcelain ring 9 is coaxial with T-shaped weldering nail 8 and is in gripping state to be welded, spring 4 restores (as shown in Figure 7), then makes torch body 1 now be displaced to treat above the solder joint of weldment 10 (as shown in Figure 8) hand or with robot or triaxial movement platform；During this, concordant with bottom porcelain ring 9 or T-shaped weldering nail 8 bottom, the bottom of T-shaped weldering nail 8 to be realized and be less than the distance bottom porcelain ring for welding pre compressed magnitude (generally 1mm～10mm), the limited block 5 of spring 4 lower end can be located at by regulation and be adjusted；
Then make torch body 1 descending, bottom porcelain ring 9 (in the case of the bottom of T-shaped weldering nail 8 is concordant with bottom porcelain ring 9) or T-shaped weldering nail 8 bottom (in the case of the bottom of T-shaped weldering nail 8 is less than bottom porcelain ring) with when contacting until weldment 10, execution stud welding (as shown in Figure 9)；
Welding terminates, after solder joint solidifies, (bottom of T-shaped weldering nail 8 has been planted to be welded in and has been treated on weldment, and porcelain ring is also set in welding position), first pass through drive mechanism drive shaft body 12 to do and propose motion, make weldering nail clip 13 up, it is separated with the head of T-shaped weldering nail 8 and returns to original state (as shown in Figure 10), then making torch body 1 up, make porcelain ring chuck 7 above be carried and be separated with porcelain ring 9 and contact (as shown in figure 11) with the head of T-shaped weldering nail 8；Continuing to make torch body 1 up, the head that can order about T-shaped weldering nail 8 is strutted flexure strip 71 by the effect that is directed downwardly toward deriving inclined-plane 74 and realizes being separated with porcelain ring chuck 7, thus completes automatic welding operation (as shown in figure 12).Circulate and so forth, can realize T-shaped weldering being followed closely and protecting automatic clamping and the welding of porcelain ring.
It addition, need explanation at this: described torch body 1 can use existing stud welding gun structure, does not do any restriction at this；The drive mechanism that wherein drive shaft body moves up and down can use existing electric magnet-spring structure and line motor dragging structure, does not the most do any restriction at this.
Finally be necessary it is pointed out here that: the foregoing is only this utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; any those familiar with the art is in the technical scope that this utility model discloses; the change that can readily occur in or replacement, all should contain within protection domain of the present utility model.
