[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] The utility model provides Figure 1-3As shown, an electric adjustable pipe column automatic riveting device comprises a connecting receiving plate body 7 and a pipe column fixing base plate tooling 1 arranged on the connecting receiving plate body 7; a pipe column fixing device 4 is arranged at the end side position of the pipe column fixing base plate tooling 1, a rivet tooling 3 is arranged at the side position at the middle position of the pipe column fixing base plate tooling 1, a pressure sensor 5 is arranged at the outer side position of the rivet tooling 3, and a rivet support block 2 is arranged at the end position of the pipe column fixing base plate tooling 1. The product is placed on the pipe column fixing base plate tooling 1, and two rivets are inserted at the same time; the pipe column fixing device 4 is pressed to fix the pipe column body, and the equipment automatically operates: the rivet support block 2 is inserted into the pipe column body forward, and the rivet tooling 3 starts to press the rivets at the same time, and the pressure sensor 5 monitors whether the pressing force is within the range. The utility model has the advantages of simultaneous riveting on both sides, using the same oil cylinder control to ensure uniform pressure on both sides, ensuring the concentricity of the product and the pressure sensor 5 monitoring whether the riveting is in place, and ensuring that the adjustment force of the product is stable and consistent.
[0022] like Figure 1 As shown, an extrusion column 8 is provided at the side of the rivet press tool 3, and the extrusion column 8 is installed and connected to the rivet press tool 3 by screws. The extrusion column 8 is used for better contact and extrusion with the rivet.
[0023] like Figure 1 As shown, a mounting base plate 6 is provided at the bottom position of the connecting plate body 7, and the mounting base plate 6 is installed and connected to the mounting base plate 6 by screws passing through screw holes. The connecting plate body 7 can make the electric adjustment column automatic riveting device maintain a certain distance from the mounting base plate 6 at the installation position, thereby avoiding the phenomenon of energy loss caused by friction with the mounting base plate 6 when the structures move.
[0024] like Figure 2 and Figure 3 As shown, because the rivet needs to be pre-placed at the specified position, it is easy to fall off when it is not extruded and connected, which affects the progress of the work. A contact support piece 11 is provided at the side position of the extrusion column 8, and a connecting bar 10 is connected to the side position of the contact support piece 11.
