Description

Technical Field

[0001] This utility model relates to the field of riveting technology, and more specifically, to a riveting device for connecting accessories. Background Technology

[0002] The fitting connection riveting device is a specialized piece of equipment that achieves efficient fastening through mechanical pressure deformation. Its core technology utilizes the plastic deformation of rivets or rivet nuts under pressure to form a permanent mechanical connection. This device typically consists of a stamping mechanism, a hydraulic system, a mold positioning mechanism, and a control system. During operation, precisely controlled pressure causes the tail of the rivet to expand and deform, forming a mushroom-shaped rivet head, thereby firmly clamping multi-layer plates or dissimilar materials. Compared to traditional welding and threaded connections, it has three significant advantages: First, the connection process does not produce thermal deformation, making it particularly suitable for heat-sensitive materials such as aluminum alloys and composite materials; second, no pre-processing of threads or welding beveling is required, and assembly can be completed in a single-sided operation, increasing efficiency by more than 50%; third, the resulting joint has vibration-resistant and fatigue-resistant characteristics, with shear strength reaching 70%-90% of the material itself.

[0003] Existing riveting devices have a fixed spacing between the two riveting points, which cannot be flexibly adjusted according to the workpiece size or riveting requirements, resulting in a limited range of applicability. This rigid structure is only suitable for connecting accessories of specific specifications. When facing riveting tasks with different spacing, molds or equipment need to be changed, which reduces production efficiency and versatility, especially in multi-specification, small-batch processing scenarios.

[0004] In summary, to improve the versatility and production efficiency of the riveting device, it is necessary to solve the problem of the inability to adjust the distance between the two riveting operation points, so that it can adapt to the riveting requirements of workpieces of different specifications, thereby enhancing the equipment's adaptability and reducing the frequency of mold changes. Utility Model Content

[0005] The accessory connection riveting device provided by this utility model aims to solve the problem that the existing riveting device cannot adjust the distance between the two riveting operation points during use, resulting in low adaptability.

[0007] In a preferred embodiment, the limiting mechanism includes a positioning component and a sliding component. The positioning component is used to position the movement of the mounting plate, and the sliding component is used to move the mounting plate left and right.

[0008] In a preferred embodiment, the positioning component includes a groove formed on the worktable, a limit plate fixed between the movable seat and the mounting plate, and the limit plate being slidably connected to the groove.

[0009] In a preferred embodiment, the sliding assembly includes two guide rails fixed to the worktable, and a slide block is slidably connected to the outer side of each guide rail. The slide block is fixed to the mounting plate by bolts.

[0010] In a preferred embodiment, the riveting mechanism includes a pressing component and a guiding component, wherein the pressing component is used to rivet the fittings and the guiding component is used to position the pressing component.

[0011] In a preferred embodiment, the pressing assembly includes a mounting base fixed to a mounting plate and a fixing plate, a cylinder mounted on the mounting base, and a pressure head connected to the output end of the cylinder.

[0012] In a preferred embodiment, the guide assembly includes two limiting rods fixed to the pressure head, and a guide sleeve is mounted on the mounting base, with the limiting rods and the guide sleeve being slidably connected through each other.

[0013] The beneficial effects of this utility model are as follows:

[0021] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Refer to the instruction manual appendix Figures 1 to 5 The accessory connection and riveting device includes a worktable 1, a fixed seat 2 fixed inside the worktable 1, a drive motor 3 mounted on the left side of the fixed seat 2, a bearing seat 4 fixed inside the worktable 1, a lead screw 5 rotatably connected between the fixed seat 2 and the bearing seat 4, the output end of the drive motor 3 is fixedly connected to the left end of the lead screw 5, the drive motor 3 is used to drive the lead screw 5 to rotate, a movable seat 6 is threadedly connected to the outside of the lead screw 5, a mounting plate 8 is provided on the movable seat 6, a limit mechanism is provided on the outside of the mounting plate 8, a fixed plate 10 is fixed on the top of the worktable 1, and a riveting mechanism is provided on the top of both the mounting plate 8 and the fixed plate 10.

[0023] It should be noted that when the drive motor 3 is in operation, it can drive the lead screw 5 to rotate. The rotation of the lead screw 5 can cause the moving seat 6, which is threaded with it, to move axially, thereby driving the mounting plate 8 to adjust its position. This allows for adjustment of the distance between the two riveting mechanisms, thereby improving the overall adaptability of the device.

[0024] Refer to the instruction manual appendix Figure 1 , Figure 3 and Figure 4 The limiting mechanism includes a positioning component and a sliding component. The positioning component is used to position the movement of the mounting plate 8, and the sliding component is used to move the mounting plate 8 left and right.

[0025] It should be noted that when the mounting plate 8 moves, the positioning component and the sliding component can limit the movement of the mounting plate 8.

[0026] Refer to the instruction manual appendix Figure 1 and Figure 3The positioning component includes a slide groove 72 formed on the worktable 1, a limit plate 71 fixed between the movable seat 6 and the mounting plate 8, and the limit plate 71 and the slide groove 72 are slidably connected.

[0027] It should be noted that when the mounting plate 8 moves, it can drive the limiting plate 71 to slide inside the slide groove 72.

[0028] Refer to the instruction manual appendix Figure 1 and Figure 3 The sliding assembly includes two guide rails 73 fixed on the worktable 1. Slide seats 74 are slidably connected to the outer sides of the two guide rails 73. The slide seats 74 are fixed to the mounting plate 8 by bolts.

[0029] It should be noted that when the mounting plate 8 moves, it causes the slide 74 to slide along the outside of the guide rail 73. The guide rail 73 can restrict the sliding direction of the slide 74, thereby improving the accuracy and stability of the movement of the mounting plate 8.

[0030] Refer to the instruction manual appendix Figure 1 and Figure 5 The riveting mechanism includes a pressing component and a guiding component. The pressing component is used to rivet the parts, and the guiding component is used to position the pressing component.

[0031] It should be noted that the pressing assembly, in cooperation with the guide assembly, can complete the riveting of the parts.

[0032] Refer to the instruction manual appendix Figure 1 and Figure 5 The pressing assembly includes a mounting base 91 fixed on the mounting plate 8 and the fixing plate 10, a cylinder 92 mounted on the mounting base 91, and a pressure head 93 connected to the output end of the cylinder 92.

[0033] It should be noted that when cylinder 92 is in operation, it can drive the pressure head 93 to press down, thereby pressing the rivet onto the part.

[0034] Refer to the instruction manual appendix Figure 5 The guide assembly includes two limit rods 95 fixed on the pressure head 93, and a guide sleeve 94 is installed on the mounting base 91. The limit rods 95 and the guide sleeve 94 are slidably connected through each other.

[0035] It should be noted that when the pressure head 93 moves, it causes the limiting rod 95 to slide inside the guide sleeve 94. The cooperation between the guide sleeve 94 and the limiting rod 95 can limit the movement of the pressure head 93.

[0036] Working principle: During operation, after the drive motor 3 starts, it drives the lead screw 5 to rotate, causing the movable seat 6, which is threaded with it, to move axially. At the same time, it drives the mounting plate 8 and the limiting plate 71 to slide along the slide groove 72. The mounting plate 8 is synchronously displaced along the guide rail 73 by the slide seat 74 fixed by bolts, realizing the adjustment of the distance between the two pressure heads 93. After the adjustment is completed, the cylinder 92 on the mounting plate 8 and the fixed plate 10 drives the pressure head 93 to press down. The pressure head 93 moves down precisely through the guide cooperation of the limiting rod 95 and the guide sleeve 94, pressing the rivet into the workpiece to complete the connection. The entire process realizes the adaptive distance through the transmission of the lead screw 5, the guide rail 73 and the slide groove 72 ensure the stability of movement, and the guide sleeve 94 and the limiting rod 95 ensure the vertical accuracy of the riveting.

[0037] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
