With the development of the social economy, more and more modular sofas, such as those with sliding backrests, have appeared on the market. These sofas are formed by assembling multiple independent sofa parts to facilitate transportation and production. The sofa parts need to be connected and fixed with hardware connectors, which places high demands on the assembly and disassembly performance of these connectors.

[0003] In the prior art, Chinese utility model patent CN215201438U discloses a fixing device for processing sofa metal parts, including a device body, a base component, a shock-absorbing spring, a round rod, a clamping plate, and a shock-absorbing bearing.

A shock-absorbing bearing is sleeved on the round rod. A protrusion is fixedly connected to the side of the round rod away from the center of the device. A fixing block is snapped onto the protrusion. Telescopic rods are fixedly connected to both the upper and lower ends of the fixing block. A shock-absorbing spring is sleeved on the telescopic rod. By setting up shock-absorbing bearings and shock-absorbing springs, the vibration generated during the processing of parts can be greatly reduced, making it more convenient for workers to operate.

[0004] Problems compared to existing technologies: During the manufacturing process of sofas, multiple surfaces of the metal parts need to be processed. Some existing sofa manufacturing fixing devices cannot flip the sofa metal parts while fixing them, which requires multiple adjustments and clamping of the metal parts during the sofa manufacturing process, and the sofa manufacturing efficiency needs to be improved.

[0005] Therefore, there is an urgent need for a fixing device for sofa processing. Utility Model Content

[0010] As a further improvement of this utility model, the inner wall of the arc-shaped clamping frame is provided with a rubber pad to prevent scratches on the surface of the sofa's metal parts.

[0011] As a further improvement of this utility model, a turntable is provided at one end of the lead screw to drive the lead screw to rotate.

[0012] As a further improvement of this utility model, the top of the workbench is provided with a clearance groove to prevent motion interference during the rotation of the square tube.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0015] 1. By incorporating lifting electric actuators, which drive dual-axis electric actuators to rise and fall via the worktable, the height of the arc-shaped clamping frame is adjusted. The dual-axis electric actuators also move the side arms closer together or further apart, adjusting the spacing of the arc-shaped clamping frame. A servo motor, connected to the square rod and square tube, drives the two drive toothed pulleys to rotate synchronously. The toothed belt drives the rotating shaft to rotate synchronously, thus rotating the sofa metal parts via the arc-shaped clamping frame. This allows for the flipping of the sofa metal parts during fixing, eliminating the need for multiple adjustments and clamping during sofa processing and improving processing efficiency.

[0016] 2. By setting up a turntable, the turntable drives the lead screw to rotate, and the lead screw drives the lifting rod to rise and fall along the limit frame, thereby driving the pressing plate to rise and fall. Under the action of the arc-shaped clamping frame, the fixing device for sofa processing can clamp and fix sofa metal parts of various specifications and shapes, enriching the functionality of the fixing device for sofa processing.
