Description

Technical Field

[0001] The utility model relates to the technical field of boring and milling machines, in particular to a tooling structure of a horizontal boring and milling machine. Background Art

[0002] Boring and milling machines are a type of processing tool commonly used in the processing industry. They combine the functions of boring machines and milling machines in one, and are mainly used for boring holes and milling planes, making processing more efficient and accurate, greatly improving product quality and labor efficiency. Boring and milling machines are divided into vertical boring and milling machines, horizontal boring and milling machines, and floor-standing boring and milling machines according to their layout. Horizontal means that the tool axis is perpendicular to the processing plane. The worktable size of existing horizontal boring and milling machines is fixed. When processing workpieces larger than the worktable, the system rigidity of the part where the workpiece exceeds the worktable is poor, resulting in tool vibration. In addition, the worktable of existing horizontal boring and milling machines has no positioning device, and cannot achieve workpiece positioning and rapid switching, resulting in low production efficiency. For example, the worktable size of the AH110 horizontal boring and milling machine is 1250mm×1100mm, and the maximum stroke of the equipment parameters is 1600mm. When processing a large number of workpieces with a length of more than 2 meters, due to the inherent length and stroke limitations of the worktable of the AH110 horizontal boring and milling machine, it is necessary to make special tooling to expand the process route of the horizontal boring and milling machine.
