Description

TECHNICAL FIELD

[0001] The utility model belongs to sofa processing technical field, concretely relates to an auxiliary frame nailing device suitable for the size change of sofa. BACKGROUND

[0002] The multifunctionality, practicality, decorative property, comfort and raw material diversity of sofa change with the different use scene, but the stability of basic structure is necessary for all types of sofa, and the standard stability of sofa inner frame is the key to the structure stability of sofa.

[0003] The present sofa frame nailing technology is not mature, and is roughly divided into two kinds of nailing technology, namely manual nailing and tooling nailing.

[0004] Manual nailing: workers take workpieces, classify and identify the building positions of each workpiece, manually hold the workpiece and nail, and need to push, pull and drag the frame being nailed to nail each part. Manual nailing requires high skill of workers, and new workers are not easy to start with, and the probability of nailing error is great. At the same time, the manual nailing of workers is prone to the frame structure skew and warping, which affects the stability of sofa. In addition, the workers have great labor intensity in pushing, pulling and dragging the frame, are prone to nailing fatigue, affect the health of workers, and the pushing, pulling and dragging is prone to damage the sofa frame not yet completed.

[0005] Tooling nailing: workers take workpieces, and each workpiece is placed in tooling, which is extruded and clamped to fix each workpiece, and workers nail each part in the frame from each angle inside and outside around the tooling. Due to the closed nailing characteristics, the workpiece feeding and discharging is difficult, each workpiece is placed in combination after clamping, and the feeding efficiency is low. After nailing, the whole frame is discharged, and each part is hindered. During nailing, workers nail the frame around the tooling, the frame is large in size, and it is time-consuming and laborious to go around, and due to the restriction of nailing tools such as air gun pipe and wire, it is difficult to go back and forth.
