[0002] The press-fit device utilizes stamping equipment and specialized joining dies to perform a rapid, high-pressure process. Based on the cold extrusion deformation of the sheet material, it forms an internal, stress-free, inlaid dot with a certain tensile and shear strength. This allows for the joining of two or more layers of sheet materials and thicknesses. It is suitable for joining steel, stainless steel, aluminum, and non-metallic interlayers. Rivetless riveting is widely used in aerospace, automotive, rail transportation, elevator platforms, busbars, air conditioners, dampers, air ducts, washing machine housings, pet cage trays, and electrical appliances.

[0016] Compared with the prior art, the present invention provides an automatic servo press assembly structure, which has the following beneficial effects:

[0017] 1. This utility model uses maXYos NC to control the servo press-fitting unit. As the core component of the assembly system, maXYmos NC monitors and controls the entire assembly process. With an intuitive touchscreen display and a built-in integrated sequencer, the system offers excellent functionality and outstanding flexibility, making it suitable for assembly processes ranging from simple to highly complex. The maXYmosNC monitor, combined with the press and IndraDrive servo drive, is used to control, monitor, evaluate, and archive force-displacement curves during assembly and press-fitting. The shape of the measured curve is used via SERCOS III to monitor and control the quality of each manufacturing step, assembly group, or entire product in real time. This means that optimal cycle times can be achieved with maximum repeatability. Because unplanned downtime is minimized, machine utilization and manufacturing process productivity are improved.

[0018] 2. The utility model monitors and controls the pressing process through three pressure sensors. The pre-pressure and subsequent pressure differ greatly, and a single pressure sensor may not be accurate enough in a certain process, thereby ensuring monitoring of the entire pressing process.
