[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] See also Figure 1-Figure 5 In this embodiment, an elevator upper sill automatic rolling riveting and palletizing production line is provided, and its main parts include a rolling device 100, a rivet-applying device 200, a riveting device 300 and a storage frame 400.

[0027] The rolling device 100 is used to roll the workpiece to form an elevator upper sill member H that has taken shape. Specifically, the rolling device 100 includes a frame 110 and rolling assemblies 120 arranged from left to right in the frame 110 to roll the workpiece into the elevator upper sill member H. In this embodiment, the rolling assembly 120 includes an upper pressing roller 120a and a lower pressing roller 120b. The upper pressing roller 120a includes a first shaft 120a-1 and an upper pressing wheel 120a-2 that surrounds the first shaft 120a-1 and has a gradually changing diameter. The lower pressing roller 120 b includes a second shaft 120b-1 and a lower pressure wheel 120b-2 surrounding the second shaft 120b-1, and the second shaft 120b-1 is connected to a rotary drive motor through a conveyor belt. When in use, the rotary drive motor drives the second shaft 120b-1 to rotate, and the second shaft 120b-1 drives the lower pressure wheel 120b-2 to rotate. At the same time, the upper pressure wheel 120a-2 rotates together with the lower pressure wheel 120b-2 to roll the workpiece to form an elevator upper sill piece H with a preliminary shape and transport it forward to the workbench 210.

[0028] The upper riveting device 200 is used to rivet the elevator upper sill member H after rolling. Specifically, the upper riveting device 200 includes a workbench 210 whose head end is integrally connected to the rear of the frame 110 and has a blocking plate 220a on the top, a support table 220 arranged at the side of the frame 110, and a claw hand robot 230 installed on the support table 220. The workbench 210 is provided with a stopper 210a perpendicular to the conveying direction of the elevator upper sill member H, which is used to intercept the elevator upper sill member H conveyed forward after rolling by the rolling device 100. The elevator upper sill piece H is provided with side baffles 210b on both sides of the workbench 210, which are used to prevent the elevator upper sill piece H from falling from both sides of the workbench 210 to the ground. When in use, when the rolling device 100 rolls the elevator upper sill piece H and is transported to the workbench 210 by the inertia force of the tail, the block 210a intercepts the elevator upper sill piece H, and then the claw robot 230 grabs the rivet on the rivet table and then deflects to the workbench 210, and rivets the elevator upper sill piece H on the workbench 210.

[0029] The riveting device 300 is used to rivet the elevator upper sill member H after the rivet is applied and transport it to the tail at the same time. Specifically, the riveting device 300 includes a sliding frame 310 that can slide along the side wall of the workbench 210, a driving mechanism 320 that drives the sliding frame 310 to slide along the workbench 210, an adsorption assembly 330 arranged at the four corners of the bottom of the sliding frame 310, and a rivet gun 340 installed at the top of the sliding frame 310 and extending to the bottom. The two side plates of the sliding frame 310 have an outer extension block 310a parallel to each other and an inner extension block 310c that is attached to the top of the workbench 210. The bottom of the outer extension block 310a is The outer extension block 310a, the bending block 310b and the inner extension block 310c surround and form a slide groove engaged with the workbench 210. The top of the workbench 210 is provided with a rack 210c along the transmission direction of the elevator upper sill member H. The driving mechanism 320 includes a mobile driving motor 320a installed on one of the side walls of the sliding frame 310 and the output end thereof passes through the interior, and a gear 320b provided on the output end of the mobile driving motor 320a and meshing with the rack 210c. The adsorption assembly 330 includes a lifting component 330a and a gear 320b provided on the lifting component 330a. After the upper rivet device 200 rivets the elevator upper sill H, the mobile driving motor 320a drives the gear 320b to rotate, so that the gear 320b drives the riveting device 300 to slide in the direction close to the rolling device 100 along the rack 210c. When the riveting device 300 abuts against the tail of the rolling device 100, the lifting component 330a of the adsorption assembly 330 drives the adsorption plate 330b to descend, and adsorbs the elevator upper sill H after the rivet is applied. After adsorbing the elevator upper sill H, the mobile driving motor 320a drives the gear 320b again. Rotate so that the gear 320b drives the riveting device 300 to slide along the rack 210c in the direction away from the rolling device 100, and during the sliding process of the riveting device 300, the rivet gun 340 performs riveting operations on the rivets on the elevator upper sill piece H. When the riveting device 300 moves to the tail of the workbench 210, the suction plate 330b releases the elevator upper sill piece H, and the elevator upper sill piece H falls into the storage frame 400. Preferably, in this embodiment, the lifting component 330a is an electric telescopic rod or a hydraulic telescopic rod, and the suction plate 330b is a vacuum suction plate or an electromagnetic suction cup.

[0030] Combination Figure 1-Figure 5In this embodiment, an automatic rolling riveting and stacking production line for elevator upper sills can, after the workpiece is rolled and reaches the workbench 210, the rivet-adding device 200 can rivet the elevator upper sill part H. After the riveting is completed, the riveting device 300 can transport, stack and store the elevator upper sill part H while performing riveting processing on the rivets. The whole process is convenient and fast, and multiple transfers are not required. The complex process of rolling the upper sill on the rolling production line to form an upper sill part with a preliminary shape, then transferring it to the riveting production line for riveting operation, and then stacking is simplified, which greatly improves the processing rate and output of the upper sill frame.
