[0030] like Figure 2 and Figure 3As shown, the present application provides a sofa frame assembly device, including a support frame 1, a platform frame 2 is fixed on the support frame 1, a rear rod limiting strip 3 is fixed on the platform frame 2, the rear rod limiting strip 3 is used to limit the rear rod placed on the platform frame 2, one side of the rear rod limiting strip 3 is located on the platform frame 2 and a front rod driving assembly 4 is provided, the front rod driving assembly 4 is used to drive the front rod placed on the platform frame 2 to move toward the rear rod placed on the platform frame 2, both ends of the rear rod limiting strip 3 are located on the platform frame 2 and side rod driving assemblies 5 are provided, the side rod driving assembly 5 is used to drive the side rods placed on the platform frame 2 to move toward the two ends of the front rod and the rear rod placed on the platform frame 2, so that the interlocking parts of the front rod, the rear rod and the two side rods are interlocked, and the two side rod driving assemblies 5 are symmetrically arranged, respectively driving the side rods at corresponding positions. The platform frame 2 is provided with a side rod limiting assembly 6 corresponding to the two side rod driving assemblies 5. The side rod limiting assembly 6 is used to limit the side rods to ensure that the front rod, rear rod and side rods are in the correct position during the assembly process, so that the fitting parts can be accurately matched, thereby improving the overall quality and stability of the sofa frame. Compared with the prior art, the front rod driving assembly 4 and the side rod driving assembly 5 replace the slow operation method of manual knocking or tool-assisted fitting, thereby improving the assembly efficiency of the sofa frame, thereby improving production efficiency, and avoiding the inconsistent fit of the fitting parts caused by manual knocking or tool-assisted fitting, thereby affecting the quality of the sofa frame.

[0031] like Figure 2 and Figure 3 As shown, the front rod drive assembly 4 includes a front rod pushing cylinder 41 and a front rod pushing plate 42. The front rod pushing cylinder 41 is fixed on the platform frame 2, and the telescopic rod of the front rod pushing cylinder 41 is fixedly connected to the front rod pushing plate 42. Specifically, the front rod pushing cylinder 41 is fixed to the bottom of the platform frame 2, and the upper end of the front rod pushing plate 42 extends to the top of the platform frame 2. The pushing surface of the front rod pushing plate 42 is parallel to the rear rod limiting strip 3. The front rod is placed on the platform frame 2, and the front rod is abutted against the front rod pushing plate 42. When the telescopic rod of the front rod pushing cylinder 41 retracts, the front rod pushing plate 42 is driven to retract, and then the front rod is driven to move toward the rear rod limiting strip 3.

[0032] like Figure 2 and Figure 3As shown, a limit rod 7 is fixedly provided on the side of the front rod pushing plate 42 close to the rear rod limit strip 3, and a limit plate 8 is fixedly provided on the end of the limit rod 7 away from the front rod pushing plate 42. A positioning block 9 for positioning the front rod is fixedly provided on the platform frame 2. When the front rod pushing cylinder 41 drives the front rod pushing plate 42 to move the front rod toward the rear rod limit strip 3 and make the rear rod limit strip 3 abut against the positioning block 9, the front rod can be clamped by the front rod pushing plate 42 and the positioning block 9. At the same time, when the front rod pushing plate 42 retracts, it drives the limit rod 7 to move toward the rear rod limit strip 3, and the limit rod 7 drives the limit plate 8 to move, so that the limit plate 8 cooperates with the rear rod limit strip 3 to clamp the rear rod placed on the platform frame 2.

[0033] like Figure 2 and Figure 3 As shown, there are two front rod pushing cylinders 41, and the two front rod pushing cylinders 41 are symmetrically arranged on the platform frame 2, so that the force on the front rod is more balanced during the pushing process, thereby improving the stability of the front rod pushing. There are two limit rods 7, and the two limit rods 7 are symmetrically arranged on the front rod pushing plate 42, so that the rear rod is more stable when clamped.

[0034] like Figure 2 and Figure 3 As shown, a connecting plate 10 is provided at the connection between the telescopic rod of the front rod pushing cylinder 41 and the front rod pushing plate 42. The telescopic rod of the front rod pushing cylinder 41 and the front rod pushing plate 42 are connected through the connecting plate 10, which increases the contact area and strength of the telescopic rod of the pushing cylinder 41 and the front rod pushing plate 42, making the connection between the telescopic rod of the front rod pushing cylinder 41 and the pushing plate more firm and stable. Specifically, the telescopic rod of the front rod pushing cylinder 41 is fixedly connected to one side of the connecting plate 10, and the other side of the connecting plate 10 is fixedly connected to the front rod pushing plate 42.

[0035] like Figure 2 and Figure 3 As shown, the side rod driving assembly 5 includes a side rod pushing cylinder 51 and a side rod pushing plate 52. The side rod pushing cylinder 51 is fixed on the platform frame 2, and the telescopic rod of the side rod pushing cylinder 51 is fixedly connected to the side rod pushing plate 52. Specifically, the side rod pushing cylinder 51 is fixed to the bottom of the platform frame 2, and the upper end of the side rod pushing plate 52 extends to the top of the platform frame 2. The side rod pushing plates 52 of the two side rod driving assemblies 5 are parallel to each other. The side rods are placed on the platform frame 2, and the side rods are abutted against the side rod pushing plates 52. When the telescopic rod of the side rod pushing cylinder 51 is retracted, the side rod pushing plates 52 are driven to retract. The side rods in corresponding positions are brought close to each other through the two side rod driving assemblies 5, and are assembled with the front rod and the rear rod through the interlocking parts at the ends.

[0036] like Figure 2 and Figure 3As shown, the side rod limiting assembly 6 includes a side rod limiting cylinder 61 and a side rod limiting block 62. The side rod limiting cylinder 61 is fixed on the platform frame 2, and the side rod limiting cylinder 61 is located above the side rod pushing cylinder 51. The telescopic rod of the side rod limiting cylinder 61 is fixedly connected to the side rod limiting block 62. Specifically, when the side rod pushing plate 52 retracts, the side rod limiting cylinder 61 drives the side rod limiting block 62 to extend and makes the side rod limiting block 62 reach the set position. After the side rod is assembled with the front rod and the rear rod, the side rod abuts against the side rod limiting block 62 to improve the assembly accuracy, and the stroke of the side rod limiting cylinder 61 and the position of the side rod limiting block 62 can be adjusted according to sofa frames of different specifications, so that the device can adapt to the assembly requirements of sofa frames of different sizes and shapes, thereby improving the versatility and flexibility of the device.

[0037] Working principle:

[0038] like Figure 4 As shown, in the initial state, the telescopic rods of the front rod pushing cylinder 41 and the side rod pushing cylinder 51 are in the extended state, and the telescopic rods of the side rod limiting cylinder 61 are in the retracted state. The front rod A1, the rear rod A2 and the two side rods A3 are placed on the platform, and the rear rod A2 is abutted against the rear rod limiting strip 3, the front rod A1 is abutted against the front rod pushing plate 42, and the two side rods A3 are respectively abutted against the side rod pushing plates 52 at corresponding positions, and the interlocking parts at the ends of the side rod A3 correspond to the interlocking parts at the ends of the rear rod A2 and the front rod A1. Then, the front rod pushing cylinder 41, the two side rod pushing cylinders 51 and the two side rod limiting cylinders 61 are started, and the telescopic rod of the front rod pushing cylinder 41 is retracted, driving the front rod pushing plate 42 to retract, and then driving the front rod A 1 moves toward the rear rod A2, and makes the front rod A1 abut against the positioning block 9, and the front rod pushing plate 42 cooperates with the positioning block 9 to clamp the front rod A1. At the same time, the limit block on the limit rod 7 abuts against the rear rod A2, and the rear rod is clamped by cooperating with the limit plate 8 and the rear rod limit strip 3. The telescopic rod of the side rod pushing cylinder 51 retracts, driving the side rod pushing plate 52 to retract, and the side rods A3 at the corresponding positions are brought close to each other through the two side rod driving assemblies 5. The side rod limiting cylinder 61 drives the side rod limiting block 62 to extend and make the side rod limiting block 62 reach the set position. After the interlocking parts of the side rod A3, the front rod A1, and the rear rod A2 are assembled, the two side rods A3 just abut against the side rod limiting blocks 62 at the corresponding positions, thereby improving the assembly accuracy.

[0039] In this embodiment, the front rod pushing cylinder 41, the side rod pushing cylinder 51 and the side rod limiting cylinder 61 are all double-axis cylinders.

[0040] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
