Description
本發明係提供一種無須回廠大修,即可就地補償工作台水平誤差之新穎工具機。 The invention provides a novel machine tool which can compensate the horizontal error of the worktable in situ without going back to the factory for overhaul.
按,工具機(Machine tool)為一種具有工作台及刀具之動力機械製造裝置,此工作台底部及工具機之間設有能相對移動之滑軌總成,而工作台頂端更具有能固定工件之基準面,然後在工件和刀具之間製造出一個相對運動,令刀具以切削或研磨等加工方式將該工件製成所需的形狀、尺寸及表面精度。 Press Machine tool is a power machinery manufacturing device with a table and a tool. The bottom of the table and the machine tool are provided with a slide rail assembly that can move relative to each other, and the top of the table is more capable of fixing the workpiece. The reference surface then creates a relative motion between the workpiece and the tool, allowing the tool to be machined to the desired shape, size and surface accuracy.
可是該工具機在運作一段時日後,工作台在切削應力、材料內應力、滑軌總成磨耗…等等多重交互作用下,會喪失其基準面在出廠時之水平度,造成所加工之工件有平行度及垂直度誤差,而無法達到精密加工要求,因此保持工作台之基準面水平度,攸關工具機加工精度與否。 However, after the machine tool has been in operation for a period of time, the table will lose its level of the reference surface at the factory due to multiple interactions such as cutting stress, material stress, and rail assembly wear, etc., resulting in the workpiece being machined. There are parallelism and perpendicularity errors, and the precision machining requirements cannot be met. Therefore, the level of the reference surface of the workbench is maintained, and the machining accuracy of the tool is not high.
一般在工作台發生水平誤差時,無法就地補償,而須回廠進行大修,其歷經拆下工作台、進行研磨及人工鏟花,方能補償工作台水平度,是以,傳統工作台水平誤差補償相當耗時耗力,除所費不貲,停產更會造成業者產能調配之困擾。 Generally, when the horizontal error occurs on the workbench, it cannot be compensated locally, but it must be returned to the factory for overhaul. After removing the workbench, grinding and artificial shovel, the level of the workbench can be compensated. Error compensation is quite time-consuming and labor-intensive. In addition to the cost, the suspension of production will cause troubles in the production capacity of the industry.
有鑑於工具機有上述之缺失,本發明人乃積極努力 研究,經多次試驗與改良,終於發展出能就地補償工作台水平誤差之本發明。 In view of the above-mentioned lack of the machine tool, the inventor is actively working hard. Research, after many trials and improvements, finally developed the invention capable of compensating for the horizontal error of the workbench in situ.
