Description

Technical Field

[0001] The utility model relates to the technical field of chair leg processing, in particular to a numerically controlled chair leg planer. Background Art

[0002] Dining chairs refer to chairs specially used for dining, which are a type of restaurant furniture. Dining chairs can be divided into solid wood chairs, steel-wood chairs, etc. according to the material; they can be divided into Chinese dining chairs, Western dining chairs, coffee chairs, etc. according to the purpose. When processing the legs of dining chairs, a planer is required. A planer is a linear motion machine tool that uses a planer to plan the plane, groove or forming surface of a workpiece. When using a planer for processing, the tool is simpler, but the productivity is lower (except for processing long and narrow planes). Therefore, it is mainly used for single-piece, small-batch production and machine repair workshops. In mass production, it is often replaced by a milling machine. The traditional planer is used because the chair legs are placed directly on the workbench, resulting in personnel needing to adjust the angle when processing different surfaces of the chair legs. This is time-consuming and labor-intensive, and the dust and waste generated by the processing are inconvenient to clean up. For this reason, we propose a CNC chair leg planer. Utility Model Content
