Description

Technical Field

[0001] This utility model belongs to the field of mechanical manufacturing technology, and in particular relates to a riveting device for sheet-like objects. Background Technology

[0002] Nut press-fitting is a type of fastener used on sheet metal, thin plates, chassis, cabinets, and other sheet-like materials. A press-fitting nut is pressed into a pre-drilled hole in the workpiece, causing plastic deformation around the hole and firmly fixing the nut to the thin plate. This creates an internal thread structure on the thin plate that effectively secures the screw.

[0003] Traditional riveting methods involve manual riveting, where nuts are secured by hammering. This method is inefficient, costly, and yields inconsistent quality. To address these issues, patent CN217394227U, "Nut Riveting Machine," proposes an automated nut riveting system to replace manual riveting, thereby improving efficiency and yield.

[0004] However, existing technologies, including the aforementioned patents, can only rivet one nut at a time, making batch processing impossible, and thus their efficiency needs further improvement. Furthermore, single-point riveting causes deformation of sheet metal, thin plates, chassis, cabinets, and other sheet-like materials, and the deformation is uncontrollable, affecting the position and accuracy of the next nut riveting. Therefore, designing a high-efficiency, low-deformation sheet-like material riveting device is a crucial technical problem that those skilled in the art need to solve. Utility Model Content

[0033] like Figures 1 to 2 As shown, this utility model discloses a sheet-like riveting device, including an upper mold 1 and a lower mold 2. A set of guide rods 1021 and guide blocks 1022 are arranged between the upper mold 1 and the lower mold 2. Further, a set of drive shafts 1023 are symmetrically arranged on the outer sides of the upper mold 1 and the lower mold 2, and the drive shafts 1023 drive the upper mold 1 or the lower mold 2 to rise and fall. In addition, the sheet-like material mentioned in this utility model can include sheet metal, profiles, etc., and also includes sheet metal parts, chassis, cabinets, and other thin-plate parts made of sheet metal, profiles, etc.

[0034] like Figure 2 As shown, at least one nut supply assembly 3 is provided on the outer side of the lower mold 2. Considering that more than one type of nut may need to be installed on a single sheet, to avoid incorrect installation positions of different types of nuts, this invention preferably provides three nut supply assemblies 3. Nuts with different signals are stored in different nut supply assemblies 3, effectively preventing incorrect nut installation positions, ensuring installation accuracy and effectiveness, and improving assembly quality. Furthermore, the number of nut supply assemblies 3 can be adjusted according to usage requirements. This invention only uses three as an example for illustration, and the specific number is not limited here.

[0035] Furthermore, such as Figures 3 to 4 As shown, the nut supply assembly 3 includes at least a supply chamber 31, a delivery pipe 32, and an assembly cavity 33. The nut supply assembly 3 delivers each nut to be assembled point-to-point, ensuring effective and accurate delivery.

[0036] At least one support component 21 is provided on the lower mold 2, and each support component 21 has a set of through holes 210 formed on its support plate 211 to facilitate the top surface of the assembly cavity 33 to pass through. The top surface of the assembly cavity 33 is flush with the top surface of the support component 21. The assembly cavity 33 is located directly below the nut mounting hole in the sheet-like object, and at least one nut for assembly is temporarily stored in the assembly cavity 33. Further, each supply chamber 31 corresponds to at least one conveying pipe 32, and each conveying pipe 32 corresponds to one assembly cavity 33. Figure 4 As shown, the assembly cavity 33 includes an assembly body 331 and a movable body 332. The movable body 332 is driven by the upper mold 1 to rise and fall relative to the assembly body 331 and its inner nut, so that the nut located at the topmost position is installed on the sheet.

[0037] Furthermore, the nut supply assembly 3 also includes a nut storage chamber 34, which is located between the supply chamber 31 and the assembly cavity 33. Specifically, it is connected to the supply chamber 31 via a first conveying pipe 321 and to the assembly cavity 33 via a second conveying pipe 322. The input end of the nut storage chamber 34 is also connected to a gas pipe 341, and the input end of the gas pipe 341 is connected to a gas source. The specific structure of the supply chamber 31 can be referenced from known vibratory feeder structures and will not be elaborated here. The nuts to be assembled in the supply chamber 31 are conveyed to the nut storage chamber 34 via the first conveying pipe 321; the nuts to be assembled in the nut storage chamber 34 are driven by the gas source to move towards the second conveying pipe 322 into the assembly cavity 33; finally, the nut to be assembled at the top moves upward relative to the moving body 332 in the assembly cavity 33 while the upper mold 1 and the lower mold 2 are closed.

[0038] like Figures 5 to 6 As shown, the lower mold 2 is provided with at least one set of support components 21 for supporting the sheet-like object, and the support components 21 are inclinedly distributed on the base plate 20 of the lower mold 2. Specifically, the support component 21 includes a support plate 211, and a set of fixing blocks 201 are provided on the base plate 20. A telescopic rod 202 is provided on the fixing blocks 201, and the top surface of the telescopic rod 202 is connected to the support plate 211. When the upper mold 1 and the lower mold 2 are closed, the support plate 211 is subjected to force and moves towards the fixing blocks 201. During this process, the telescopic rod 202 contracts synchronously and moves upward synchronously with the upper mold 1 after reaching its limit position. It can be seen that the support plate 211 is a floating plate, which reduces the surface contact with the base plate 20 during use, thereby reducing friction and extending its service life.

[0039] The support assembly 21 further includes positioning blocks 212 and support blocks 213 disposed on the support plate 211. The positioning block 212 is provided with positioning pins 2121, which are located at both ends of the support plate 211, with their top surfaces being conical and protruding from the upper surface of the positioning block 212. The positioning pins 2121 penetrate the sheet-like object and provide initial positioning, reducing its movement during assembly and ensuring accurate riveting. The support blocks 213 are spaced apart on the support plate 211, with at least one assembly cavity 33 between adjacent support plates 211. The spaced-apart placement of the support blocks 213 on the support plate 211 ensures the stability of the sheet-like object while providing clearance for the riveting bolts, reducing interference during the riveting process.

[0040] like Figure 6As shown, a set of limiting blocks 214 are also provided on the support plate 211. The limiting blocks 214 are located outside the support block 213 and form a gap between them that is not less than the thickness of the sheet. The limiting blocks 214 can limit the boundary of the sheet. At the same time, when the sheet is processed into an L-shaped bent part as shown in this utility model, the limiting blocks 214 can place one of the bent edges of the bent part between the limiting blocks 214 and the support block 213, further stabilizing the position of the sheet and ensuring its stability during assembly.

[0041] like Figure 5 or Figure 6 As shown, at least one sensor 215 is also provided on the support plate 211, and the top surface of the sensor 215 is lower than the top surface of the support block 213. The sensor 215 can be a known proximity sensor, infrared sensor, or fiber optic sensor, etc., and its specific type is not limited here. The sensor 215, the support block 213, and the positioning block 212 are arranged along the axial direction of the support plate 211. The sensor 215 can detect whether there is a piece to be assembled on the support assembly 21, and send a self-starting signal to the control center in a timely manner to improve the degree of automation.

[0042] like Figure 5 As shown, the support assembly 21 in this utility model preferably includes a first support group 2101, a second support group 2102, and a third support group 2103. The first support group 2101 and the second support group 2102 are provided with the assembly cavity 33 and the sensor 215, respectively. The top surface of the assembly cavity 33 on the first support group 2101 is higher than the top surface of the assembly cavity 33 on the second support group 2102, which can be adjusted according to the product's fitting height. The third support group 2103 is a detection station, on which a set of sensors 215 are provided. The top surface of the support block 213 on the third support group 2103 is higher than the top surface of the support block 213 on the second support group 2102, but lower than the top surface of the support block 213 on the first support group 2101. Different types of nuts are assembled on the sheet material using the first support group 2101 and the second support group 2102. After assembly, the sheet material is moved to the third support group 2103. The sensor 215 detects whether all the nut mounting holes on the sheet material are equipped with nuts, so as to ensure that any missing sheet material is detected in time and improve quality.

[0043] like Figures 7 to 8As shown, a set of pressure head assemblies 11 are formed on the upper mold 1, and the pressure head assemblies 11 are inclinedly disposed on the fixed plate 10 of the upper mold 1. The pressure head assembly 11 includes a first pressure head group 1101, a second pressure head group 1102, and a third pressure head group 1103, which correspond to the first support group 2101, the second support group 2102, and the third support group 2103, respectively. The first pressure head group 1101 and the second pressure head group 1102 include pressure blocks 111 fixed to the fixed plate 10 and pressure heads 112 disposed on the pressure blocks 111. The pressure blocks 111 and pressure heads 112 are staggered with the support blocks 213 and correspond one-to-one with the assembly cavity 33. The third support group 2103 includes a set of pressure blocks 111, and the pressure blocks 111 located on the third support group 2103 correspond one-to-one with the support blocks 213. After the nut assembly is completed and the sheet material moves onto the third support group 2103, it is uniformly pressed by the pressure block 111 on the third pressure head group to play a shaping role and further improve the flatness of the sheet material.

[0044] Furthermore, the pressure blocks 111 on the first pressure head group 1101 and the second pressure head group 1102 are disposed between the fixed plate 10 and the mounting plate 110, and a set of pressure plates 113 are disposed on the lower surface of the mounting plate 110, with the pressure head 112 penetrating through the pressure plates 113. By pressing the outer periphery of the sheet-like object's nut mounting hole during the riveting process using the pressure plates 113, the sheet-like object is subjected to uniform force while reducing the rapid expansion deformation of the nut mounting hole, thereby reducing the deformation of the sheet-like object during assembly and improving assembly quality.

[0045] Therefore, the general working process of this utility model is as follows: While the upper mold 1 moves towards the lower mold 2, the nut supply assembly 3 is activated, supplying nuts to the nut storage chamber 34 via the supply chamber 31. The nut to be installed is then driven by an air source on the nut storage chamber 34 to move through the delivery pipe 32 into the assembly cavity 33. When the upper mold 1 and lower mold 2 close, the nut to be assembled at the top is riveted into the nut mounting hole of the sheet. By closing the upper and lower molds in one operation, a group of nuts can be riveted onto the sheet in batches, achieving fully automated installation, ensuring the stability and consistency of the assembled nuts while improving assembly efficiency. Furthermore, riveting multiple nuts at once effectively reduces stress deformation of the sheet and improves assembly quality.

[0046] The working process of this utility model is as follows:

[0047] S1, the sheet to be assembled is placed on the first support group 2101; the nut to be assembled is conveyed into the assembly cavity 33 on the first support group 2101 by one or two of the nut supply assemblies 3;

[0048] S2, the sensor 215 triggers a material presence signal, activating the upper mold 1 and driving it to move towards the lower mold 2 until the pressure head 112 moves to the mounting hole of the sheet-like object; and during the mold closing process, the moving part of the assembly cavity 33 is driven to retract, while the uppermost nut to be assembled in the assembly cavity 33 is forcefully pressed into the mounting hole of the sheet-like object; thus completing the process. Figure 8 The initial batch assembly of nuts is shown; this step and step S1 can be performed simultaneously.

[0049] S3, the upper mold 1 is reset, and at the same time, a person or a robot arm removes the sheet from the first support group 2101 and moves it to the second support group 2102; during the movement, the sheet can be flipped according to the processing requirements.

[0050] S4, the nuts to be assembled are conveyed into the assembly cavity 33 on the second support group 2102 by one or two of the nut supply assemblies 3; this step and step S3 can be performed simultaneously;

[0051] S5, Repeat step S2 above; complete as follows: Figure 9 The second batch of nut assembly is shown;

[0052] S6, the upper mold 1 is reset, and at the same time, a person or a robot arm removes the sheet-like object from the second support group 2102 and moves it to the third support group 2103;

[0053] S7, the sensor 215 triggers a material presence signal, activating the upper mold 1 and driving it to move towards the lower mold 2 until it reaches the desired position. Figure 10 The nut assembly detection state is shown. At this time, the pressure block 111 abuts against the upper surface of the sheet. At the same time, the sensor 215 detects whether a nut is installed in the nut mounting hole of the sheet. If a missing assembly is found, an alarm signal is issued, indicating that there is an assembly quality problem and that the material needs to be processed again after removal. Otherwise, no alarm signal is issued, and the sheet is removed after the upper mold 1 is reset.

[0054] This utility model has many other embodiments. All technical solutions formed by equivalent transformation or equivalent transformation fall within the protection scope of this utility model.
