Description

Technical Field

[0001] The invention belongs to the technical field of planer equipment, and in particular relates to a spiral grooving assembly for a gantry planer. Background Art

[0002] At present, the worktable of the known ordinary planer can only make reciprocating linear motion. The tool holder installed on the upper part of the ordinary planer moves in a direction perpendicular to the worktable surface or in a direction parallel to the worktable surface. After the worktable completes a reciprocating motion, the tool holder makes a feeding motion in the feeding direction. During this process, the workpiece only moves linearly with the worktable, so only linear grooves or planes can be planed.

[0003] In order to realize the processing of curved surfaces or spiral oil grooves, a fourth week is usually installed on the workbench to control the rotation of the workpiece. However, the workpiece needs to be raised during the processing to facilitate rotation. This processing method will reduce the rigidity of the workpiece. During the planing process of the workpiece, due to the long length of the workpiece, deformation will occur, resulting in reduced processing accuracy. In addition, when processing the same part, multiple tools will be used. Traditional planers need to frequently replace tools during the processing, resulting in reduced processing efficiency.
