Description

Technical Field

[0001] The invention relates to the technical field of rear leaf spring seat assembly welding, in particular to a novel rear leaf spring seat assembly welding device. Background Art

[0002] At present, the rear leaf spring seat used in the rear axle of the light truck drive is mainly composed of three parts: the upper plate, the lower plate and the side plate. The rear leaf spring seat is connected to the rear axle of the light truck drive by a punching and welding structure. When welding the bridge shell, the upper plate, the lower plate and the side plate need to be welded to the bridge shell, and the coaxiality of the holes between the upper plate, the lower plate and the side plate needs to be ensured. Therefore, when welding the bridge shell accessories, the upper plate, the lower plate and the side plate of the leaf spring seat are positioned by the leaf spring seat inclined plate and the latch, and then welded to the bridge shell. The U-shaped hole size of the side plate is large, and the latch and the U-shaped hole are not aligned. The gap between the holes is large, and there is a gap during positioning, which makes it easy for the side plate to enter the holes of the upper and lower plates, resulting in poor consistency in the quality of the welded leaf spring seat. When installing the leaf spring on the whole vehicle, it makes it difficult to install the U-bolt, resulting in subsequent rework and repair of the entire bridge. When the rear leaf spring seat is welded to the bridge housing, the upper plate, lower plate, side plate and other loose parts are welded to the bridge housing separately. This welding method is inefficient, which affects the welding efficiency between the rear leaf spring seat and the bridge housing.

[0046] It should be noted here that: through the setting of the contraction component, when the push plate 905 continues to push the push rod 906, when each adjustment plate 603 abuts against the inner walls of the insertion holes of the upper plate 101 and the side plate 102, the push plate 905 will move away from the upper plate 101 under the action of the reverse driving force and the guiding action of the contraction component, thereby providing a moving space for the clamping plate 504 to continue to approach the upper plate 101.

[0048] It should be noted here that the reset assembly is provided to provide guidance and reset functions for the movement of the push rod 906 .

[0049] Working principle: When welding the leaf spring seat to the rear axle of the light truck drive, first pre-weld the upper plate 101 and the side plate 102 or the lower plate and the side plate 102. When pre-welding the upper plate 101 and the side plate 102, place one side of the side plate 102 on the auxiliary plate 401, and use the inclined surface 403 of the auxiliary plate 401 to provide auxiliary positioning for the placement of the side plate 102. When placing the side plate 102 on the auxiliary plate 401, insert the side plate 102 into the positioning pin 301. After the installation of the side plate 102 is completed, place the upper plate 101 on the side of the second vertical plate 202 away from the first vertical plate 201, and make the side plate 102 pass through the two positioning pins 301.

[0050] After the side plates 102 and the upper plate 101 are placed, the cylinder 505 is started. Under the pushing action of the cylinder 505, the pressing plate 504 is pushed to move close to the upper plate 101. In the process of the pressing plate 504 moving close to the upper plate 101, the pushing plate 905 on one side of the L-shaped plate 904 will be synchronously driven to move close to the positioning pin 301. In the process of the pressing plate 504 moving close to the upper plate 101, the pushing plate 905 will first be against the pushing rod 906 on the positioning pin 301. Since the elastic force of the first spring 1006 is greater than the elastic force of the second spring 1104, the two circular plates 701 slide in the adjustment cavity 601 under the pushing action of the pushing plate 905 on the pushing rod 906.

[0051] When the two circular plates 701 slide in the adjustment cavity 601, they will push each rotating plate 702 to rotate. Then, during the rotation of each rotating plate 702, the driving force and the guiding action of the guide assembly will cause each adjusting plate 603 to move away from each other, so that the two groups of adjusting plates 603 are respectively against the inner walls of the insertion holes of the upper plate 101 and the side plate 102. Therefore, the coaxiality of the hole between the side plate 102 and the upper plate 101 is improved through the centering adjustment action of the two groups of adjusting plates 603, thereby improving the welding quality between the side plate 102 and the upper plate 101.

[0052] When the push plate 905 continues to push the push rod 906, after each adjustment plate 603 abuts against the inner wall of the insertion hole of the upper plate 101 and the side plate 102, the push plate 905 will move away from the upper plate 101 under the action of the reverse driving force and the guiding action of the contraction component, thereby providing a moving space for the pressing plate 504 to continue to approach the upper plate 101;

[0053] When the cylinder 505 pushes the clamping plate 504 to continue to approach the upper plate 101, when the clamping plate 504 abuts against the side wall of the upper plate 101, the cylinder 505 is stopped. At this time, the upper plate 101 is fixed under the clamping effect of the clamping plate 504 and the limiting effect of the positioning component and the adjustment component. After the upper plate 101 and the side plate 102 are fixed, the upper plate 101 and the side plate 102 can be welded to form an L shape. After the side plate 102 and the upper plate 101 are welded, the cylinder 505 can be started again to release the clamping plate 504. By pressing against the upper plate 101, the upper plate 101 and the side plate 102 welded into an L shape can be removed and then welded to the bridge housing body, thereby improving the accuracy of subsequent welding and reducing the risk of poor welding quality consistency due to coaxiality deviation of the holes among the upper plate 101, the lower plate and the side plate 102, thereby reducing the probability of subsequent rework and repair of the entire bridge, and by pre-welding the upper plate 101 and the side plate 102 or the lower plate and the side plate 102, the assembly and modularization of the leaf spring seat welding are improved, thereby improving the welding efficiency between the rear leaf spring seat and the bridge housing.
