Description

Car seat sheet metal laser welding anchor clamps

Technical Field

The utility model relates to a welding jig especially relates to a car seat sheet metal laser welding anchor clamps.

Background

In the process of manufacturing various parts by using sheet metal, a connecting technology is inevitably adopted, and the performance of a connecting joint influences the performance of the whole structural member. Welding is an important way in metal joining, and the quality of a metal welded joint has become a key process for metal applications. After metal welding, defects such as unfused, inclusion, pores, crystal cracks and the like are easily formed in a welding line; in addition, defects such as undercut and warp deformation are likely to occur during welding. Many of the drawbacks are due to poor fixturing during the welding process. Therefore, a special welding fixture is needed to fix the parts to be welded so as to reduce welding deformation as much as possible. In the prior art, the pressing plates are commonly used for clamping parts to be welded respectively, and the welding positions are not easy to be tightly attached and are easy to warp in the mode, so that the welding quality is influenced.

SUMMERY OF THE UTILITY MODEL

To the above-mentioned prior art defect, the utility model discloses a task lies in providing a car seat sheet metal laser welding anchor clamps, solves the welding position problem of upwarping, improves welding quality.

The utility model discloses technical scheme is such: the utility model provides a car seat sheet metal laser welding anchor clamps, includes backing plate, clamp plate and roof, through set screw all around to fixed connection in proper order from lower to upper, constitute between backing plate and the clamp plate and hold the space of treating a welding, leave the clearance between clamp plate and the roof, set up the welding window that corresponds from top to bottom on clamp plate and the roof, the edge that lies in welding window on clamp plate and the roof is equipped with a plurality of screw holes that push down that correspond from top to bottom, the threaded hole that pushes down is equipped with down the screw.

Further, the press-down threaded holes on the same side of the welding window are at least two.

Furthermore, the welding window is symmetrically arranged with the downward pressing threaded holes on the two sides.

Further, a spacing ring is sleeved on the fixing screw and arranged between the pressing plate and the top plate.

Furthermore, a groove is formed in the surface of the base plate corresponding to the welding window.

Compared with the prior art, the utility model the advantage lie in: the rectangular frame is formed by the pressing plate, the top plate and the fixing screws on the periphery, then the pressing screws are used for pressing and fixing the welding part on two sides of the welding position, the warping problem caused by the simple fixing of the pressing plate can be avoided, the double-layer structure of the pressing plate and the top plate can also avoid the situation that the pressing plate deforms due to heating and influences the pressing screws to fix the welding part, and the clamp is simple in structure and rapid and convenient to install.

Detailed Description

The present invention will be further described with reference to the following examples, which should not be construed as limiting the invention.

Referring to fig. 1 to 4, the laser welding jig structure for a thin plate of an automobile seat according to the present embodiment includes a backing plate 1, a pressing plate 2, and a top plate 3. The backing plate 1 is arranged at the lowest part and used for bearing a piece to be welded, a groove 4 is formed in the middle of the backing plate 1, and during welding, a welding seam of the piece to be welded is arranged above the groove 4. Four screw holes 5 are arranged around the base plate 1 and used for connecting fixing screws 6. The pressing plate 2 is arranged above the base plate 1, the rectangular welding window 7 is formed in the middle of the pressing plate 2 and in the position corresponding to the groove 4, two pressing threaded holes 8 are formed in the two sides of the welding window 7 respectively, and the pressing threaded holes 8 in the two sides are symmetrically arranged by taking the axis of the welding window 7 as a symmetry axis. Four through holes 9 are arranged around the pressure plate 2 and penetrate through the fixing screws 6. The top plate 3 is arranged above the pressing plate 2, the structure of the top plate 3 is the same as that of the pressing plate 2, the rectangular welding window 10 is arranged in the middle of the top plate 3 and in the position corresponding to the groove 4, two pressing threaded holes 11 are respectively arranged on two sides of the welding window 10, and the pressing threaded holes 11 on the two sides are symmetrically arranged by taking the axis of the welding window 10 as a symmetry axis. Four through holes 12 are arranged around the top plate 3 and penetrate through the fixing screws 6.

When the laser welding clamp for the automobile seat sheet is used, a to-be-welded part is aligned and placed on the base plate 1, a welding seam of the to-be-welded part is placed above the groove 4, the pressing plate 2 is placed on the to-be-welded part, the through holes 9 on the periphery of the pressing plate 2 are aligned with the screw holes 5 of the base plate 1, and the spacing rings 13 are placed at the through holes 9 of the pressing plate 2. The top plate 3 is placed on the spacing ring 13, and the through holes 12 on the periphery of the top plate 3 are aligned with the through holes 9 on the periphery of the pressing plate 2. The fixing screws 6 are screwed into the screw holes 5 of the base plate 1 for fixing after sequentially passing through the through holes 12 of the top plate 3, the spacing rings 13 and the through holes 9 of the pressure plate 2, the fixing screws 6 are completely screwed after final adjustment is carried out on a part to be welded, then the lower pressing screws 14 are screwed into the lower pressing threaded holes 8 and 11 of the top plate 3 and the pressure plate 2 and are contacted with the surface of the part to be welded, and the part to be welded is pressed and fixed at the periphery of a welding seam.
