Description
Technical field
A kind of self-pierce riveting cross type joint clamping assistant device is the utility model is related to, belongs to jig Design field.
Background technology
Self-piercing riveting plays great role as a kind of structural connectivity part largely used in automobile manufacturing field.From
It is a kind of cold interconnection technique for being used to connect two or more sheet metal that sleeving and riveting, which connects,.Special rivet penetrate upper strata sheet material it
Afterwards, the hollow structure expansion of rivet is pierced into top plate and is not pierced into bottom sheet material in the presence of riveting mould, so as to be formed firmly
Riveting point.At present, when self-piercing riveting cross type joint is tested, tested using hand-held test specimen, test specimen is not consolidated
Determine pre-pressing, not only result in that warpage occurs in test specimen and cruciform joint perpendicularity is inadequate, and certain potential safety hazard be present.It is right
What in such case also without good ameliorative way, therefore it is badly in need of wanting a kind of self-pierce riveting cross type joint clamping assistant device
The defects of to overcome existing experimental method.
The content of the invention
The utility model provides a kind of self-pierce riveting cross type joint clamping assistant device, can improve in self-piercing riveting ten
Because test specimen does not have the deficiency that pre-pressing causes test specimen warpage occur in the experiment of font joint；Cross type joint perpendicularity is improved,
Ensure the reliability of follow-up test；The safety coefficient of experiment is improved, avoids holding test specimen wound during experiment；Improve experiment effect
Rate, without clamping test specimen repeatedly, it is easy to accomplish automated production.
The technical solution of the utility model is：A kind of self-pierce riveting cross type joint clamping assistant device, including upper fixed branch
Seat 1, interior hexagonal screw rod 2, spring 3, sliding clamp 4, cross bearing 5, hanger 6, bore of the punch I 7, countersunk head screwed hole 8, bore of the punch II
9th, countersunk head unthreaded hole 10, die hole 11, groove 12 and nut 13；
Bore of the punch I 7 is provided among the hold-down support 1, the surrounding of hold-down support 1 is uniformly provided with four countersunk head screwed holes 8, sliding
Bore of the punch II 9 is provided among dynamic pressure plate 4, the surrounding of sliding clamp 4 is uniformly provided with four countersunk head unthreaded holes 10, hold-down support 1 and drift
End is coordinated by hanger 6 is installed, and sliding clamp 4 is coordinated with drift by the gap of bore of the punch II 9, and hold-down support 1 is pressed with sliding
Plate 4 is connected by four interior hexagonal screw rods 2 through countersunk head screwed hole 8 and countersunk head unthreaded hole 10 with the screw thread of nut 13, fixed branch
Spring 3 is cased with interior hexagonal screw rod 2 between seat 1 and sliding clamp 4, cross bearing 5 is matched somebody with somebody with lower mould by the interference of die hole 11
Attach together and match somebody with somebody, the upper surface of cross bearing 5 is provided with vertical cruciform groove 12.
Operation principle of the present utility model is：
Before experiment, test specimen is placed in groove 12 and positioned, in experiment, sliding clamp 4 is transported downwards with nose of punch
Dynamic, the lower surface of sliding clamp 4 first contacts with test specimen, carries out precompressed to test specimen under spring force, and drift contacts with test specimen
Then riveting process starts, and then drift moves upwards, and sliding clamp 4 still contacts progress under being acted on due to the elastic force of spring 3 with test specimen
Shaping, final sliding clamp 4 leave test specimen with upper punch, and experiment is completed.
The beneficial effects of the utility model are：
1st, by using the utility model, test specimen does not have pre-pressing when can improve self-piercing riveting cross type joint, causes
There is the deficiency of warpage in test specimen.
2nd, by using the utility model, it is ensured that the perpendicularity of cross type joint, obtained for follow-up test reliability
Ensure.
3rd, by using the utility model, the safety coefficient of experiment can be improved, the device can be without hand-held test specimen.
4th, by using the utility model, test efficiency can be improved, without clamping test specimen repeatedly, it is easy to accomplish automatic
Change.
