[0024] Further, in the embodiment, the conveying mechanism of the used riveting machine includes a conveying chain. The conveying chain is arranged above the riveting workbench 1. Both ends of the conveying chain are rotatably arranged on the support frame 4 through conveying sprockets. The support frame 4 is installed and connected to the riveting workbench 1. Both of the two conveying sprockets are connected by a rotating shaft to a speed reducer 11 for driving the conveying sprocket to rotate. The two speed reducers 11 are arranged on both sides of the riveting workbench 1 and connected to the riveting workbench 1. A number of processing fixtures 2 for placing and limiting automotive sheet metal parts and capable of being conveyed and moved along with the conveying chain are installed and connected on the conveying chain (in the attached drawings, the conveying chain and the conveying sprockets are not marked). By sequentially placing the automotive sheet metal parts or automotive components to be riveted in the provided processing fixtures 2, and then controlling the two speed reducers 11 to start "synchronously", the conveying chain drives these processing fixtures on the support frame 4 to convey and move the automotive sheet metal parts or automotive components to a suitable position below the discharging mechanism. The provided discharging mechanism conveys and moves the rivets required for riveting into these processing fixtures. In the embodiment, the provided discharging mechanism includes a rivet vibrating feeder 5 (an existing mechanical device). The output port of the rivet vibrating feeder 5 is installed and connected to an electric conveying track 51 for conveying the rivets in the rivet vibrating feeder 5 to the processing fixtures.

The processing jig 2 can move through between the limiting clamp block 32 and the fixed clamp plate 34 under the drive of the conveying chain. When the punching press 3 is used to rivet the automotive sheet metal part or automotive component in the processing jig 2 passing from below, at this time, the hydraulic rod 33 is controlled to drive the limiting clamp block 32 to move towards one side of the processing jig 2 until the limiting clamp block 32 abuts against one side surface of the processing jig 2. At the same time, at this time, the processing jig 2 is "position-limited and fixed" by the limiting clamp block 32 and the fixed clamp plate 34 and remains in this position. Subsequently, the lifting hydraulic cylinder is controlled to drive the punching press 3 to move downward towards the processing jig 2, and the punching drill is driven by the punching press 3 to perform riveting treatment on the automotive sheet metal part or automotive component of the processing jig 2.

[0026] Further, in the embodiment, after riveting the automotive sheet metal parts or automotive components of the processing jig 2, in order to ensure the quality of the "riveting", an inspection mechanism for inspecting the automotive sheet metal parts after riveting in the processing jig 2 is provided on the side of the punching press 3 away from the rivet vibrating feeder 5; the provided inspection mechanism includes an inspection seat 6, the inspection seat is arranged above the processing jig 2, one end of the inspection seat 6 is slidably connected to the support column 61 in a liftable manner, and the bottom end of the support column 61 is connected to the riveting workbench 1; the end of the inspection seat 6 away from the support column is provided with a through opening, a hydraulic push rod 62 is arranged at the end of the inspection seat 6 away from the support column 61, the output rod body of the hydraulic push rod 62 is telescopically arranged in the hollow cavity of the inspection seat 6, and the rod end of the hydraulic push rod 62 placed in the hollow cavity of the inspection seat 6 is connected to an inspection rod 63, one end of the inspection rod 63 away from the rod body of the hydraulic push rod 62 passes through the bottom end of the inspection seat 6 in a movable manner and is movably arranged above the processing jig 2.

When the processing jig 2 after preliminary "riveting" passes under the inspection seat 6 of this inspection mechanism, at this time, through the feedback of the "inductor" setting, the set inspection seat 6 is controlled to move downward along the support column 61 to a suitable position, and then the inspection rod 63 is driven to move to a suitable position above the processing jig 2 (a suitable position above the riveting position of the automotive sheet metal parts or automotive components in the processing jig 2) by controlling the hydraulic push rod 62; after adjustment, then the inspection seat 6 is driven to move along the guide rod 65 and under the "guiding" cooperation of the support column 61 by controlling the cylinder 66, and the inspection rod 63 is driven by the inspection seat 6 to the "riveting" position of the automotive sheet metal parts or automotive components in the processing jig 2 below, and further "riveting" is carried out to ensure the quality of riveting.
