Abstract
Description
Technical Field
[0001] This utility model relates to the field of rivetless stamping technology, and in particular to an electric servo rivetless riveting device. Background Technology
[0002] The electric servo nailless riveting equipment is a device that uses a stamping machine and a special connecting mold. Through a rapid, high-pressure processing step, it creates a stress-free, internally embedded dot with certain tensile and shear strength by cold extruding and deforming the sheet material itself. This allows for the connection of two or more layers of sheet materials of different thicknesses. The equipment boasts a high degree of automation, capable of single-point or multi-point simultaneous connection, non-destructive connection strength testing, and fully automated monitoring. It offers high production efficiency and requires no special consideration for the sheet surface, leaving the original plating or paint layers at the connection point undamaged.
[0003] Chinese invention patent application CN116833363A discloses an SPR automatic blow-feed rivet press-fit device. This patent includes a rivet storage mechanism, a rivet feeding mechanism, and a rivet pressing mechanism. The rivet storage mechanism stores rivets, and the rivet feeding mechanism is connected to both the storage and pressing mechanisms to transport rivets from the storage mechanism to the pressing mechanism. This design enables automatic rivet feeding, sorting, and loading. A pressure sensor monitors the pressure of the pressed rivets to prevent overload, and a rotary encoder tracks the rivet displacement for precise control. The servo motor ensures high pressing speed while a synchronous belt reduces noise. The servo motor is compact, has high overload protection, and can be effectively integrated with robots for automated operations. The product has good compatibility, requiring no complicated tooling changes, and can be used for riveting various material combinations. It provides a clean working environment with no smoke or oil pollution, low energy consumption, and low operating costs.
[0004] In existing technologies, overlapping metal parts are directly stamped using a cylinder rod to achieve rivetless stamping. However, the cylinder rod may shift due to stress during both linear motion and stamping, leading to misalignment of the stamped hole. Therefore, improvements are needed. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an electric servo nailless riveting device.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An electric servo-driven nail-free riveting device includes a copper plate and further includes:
[0008] The positioning component includes an aluminum plate that is mated and installed on one side of a copper plate. The corners of the copper plate and the aluminum plate are covered with baffles. A base plate is fixedly installed at the bottom of the baffles. The stamping part of the base plate is provided with stamping holes.
[0009] A further technical solution involves an L-shaped baffle made of reinforced metal.
[0010] Further technical solutions also include:
[0011] The stamping component limiting assembly includes a bracket that is mounted on the side of the baffle plate, a top plate that is fixedly mounted on the top of the bracket, a flange that is mounted on one side of the top plate, a guide tube that is mounted on one side of the flange, a stamping rod that is slidably mounted inside the guide tube, a stamping block that is provided at the end of the stamping rod, and a cylinder that is mounted on the other side of the stamping rod.
[0012] In a further technical solution, the flange installation position corresponds to the stamping hole, and bolts are provided around the flange.
[0013] A further technical solution is to ensure that the stamping dimensions of the stamping block are consistent with the diameter of the stamping hole.
[0014] Further technical solutions also include:
[0015] The waste collection assembly includes a rod that is mounted on one side of a base plate, and a waste trough is mounted on the bottom of the rod.
[0016] A further technical solution involves detachably connecting the waste trough to the bottom of the rod.
[0017] Compared with the prior art, this utility model provides an electric servo nail-free riveting device, which has the following beneficial effects:
[0018] By setting up positioning components, L-shaped baffle structures are set at the side corners of the overlapping metal plates. During the setting process, these baffles ensure that the overlapping metal plates inside remain aligned, thereby avoiding the problem of misalignment during the stamping process.
[0019] By setting up a stamping component limiting assembly, which places the bracket and top plate on one side of the baffle plate, and limiting the movement of the cylinder's stamping rod on a predetermined track by fixing the guide tube with a flange, this setting avoids the problem of the stamping rod shifting during the stamping process or during linear motion, thus preventing stamping failure.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0026] Example 1: Refer to Figure 1 - Figure 4 An electric servo nail-free riveting device includes a copper plate 1, and further includes:
[0027] The positioning component 2 includes an aluminum plate 5 that is mated and installed on one side of the copper plate 1. The copper plate 1 and the aluminum plate 5 are stacked on top of each other to achieve a rivet-free stamping effect. A baffle plate 6 is installed around the corners of the copper plate 1 and the aluminum plate 5 to achieve a positioning effect at the corners and prevent misalignment. A base plate 7 is fixedly installed at the bottom of the baffle plate 6. The stamping part of the base plate 7 is provided with stamping holes 8 for the extrusion stamping of the stamping block 15.
[0028] The electric servo nailless riveting device has an L-shaped baffle plate 6 made of reinforced metal to prevent deformation during the process.
[0029] The aforementioned electric servo nailless riveting device further includes:
[0030] The stamping part limiting assembly 3 includes a bracket 9 mounted on the side of the baffle plate 6, which limits the mounting top plate 10. The top plate 10 is fixedly mounted on the top of the bracket 9. A flange 11 is mounted on one side of the top plate 10, which is used to position and install the guide tube 13, thereby achieving the effect of positioning and guiding the stamping rod 14. The guide tube 13 is mounted on one side of the flange 11, and the stamping rod 14 is slidably mounted inside the guide tube 13. A stamping block 15 is provided at the end of the stamping rod 14, and a cylinder 16 is mounted on the other side of the stamping rod 14. The cylinder 16 is a component that controls the movement of the stamping rod 14.
[0031] In the aforementioned electric servo nailless riveting device, the installation position of the flange 11 corresponds to the stamping hole 8, ensuring a stable alignment during stamping. Bolts 12 are provided around the flange 11.
[0032] In the aforementioned electric servo nailless riveting device, the stamping size of the stamping block 15 is consistent with the diameter of the stamping hole 8.
[0033] The aforementioned electric servo nailless riveting device further includes:
[0034] Waste collection assembly 4 includes a rod 17 that is connected to one side of the base plate 7. A waste trough 18 is connected to the bottom of the rod 17. The waste trough 18 is the part where the stamped original sheet is collected.
[0035] In the aforementioned electric servo nailless riveting device, the waste trough 18 is detachably connected to the bottom of the rod 17, ensuring convenient material discharge when the device is not in use.
[0036] Working principle:
[0037] In the actual design process, this utility model addresses the following defects in the prior art: "In the prior art, overlapping metals are directly stamped using a cylinder rod to achieve rivetless stamping. However, the cylinder rod may shift due to stress during both linear motion and stamping, leading to displacement of the stamping hole. Therefore, improvements are needed." Therefore, the following components are specifically proposed: positioning component 2, stamping part limiting component 3, and waste collection component 4.
[0038] Positioning component 2:
[0039] The main function of this component is to limit the position of the stacked copper plate 1 and aluminum plate 5, preventing stamping misalignment during the stamping process. We have installed an L-shaped baffle 6 at the corner of the joint between the copper plate 1 and aluminum plate 5. This baffle 6 directly prevents misalignment during the stamping process.
[0040] Stamping Part Limited Component 3:
[0041] This component primarily guides the movement path of the stamping rod 14, which serves as the output end of the cylinder 16, thereby preventing the stamping rod 14 from deviating from its running path and ultimately causing stamping deviation. Therefore, to achieve the positioning effect, the bracket 9 and the top plate 10 are fixed to one side of the baffle plate 6, and the guide tube 13 is fixed via the flange 11 to guide the movement of the stamping rod 14. This ensures that the stamping block 15 always acts on a specific part during the stamping process without deviation.
[0042] Waste collection component 4:
[0043] This component is mainly used to collect the metal sheets that fall off during the stamping process. The scrap tank 18 directly collects the stamped sheets generated at the upper stamping hole 8.
