Description
本創作係與車刀有關,特別是有關於一種車刀桿與車刀座結合結構。This creation department is related to the turning tool, especially regarding the combination of a turning tool holder and a turning tool holder.
因應不同的加工需求,以及刀片無可避免的磨耗,刀具時常有替換的需求,將刀具分為安裝刀片的刀座與安裝於機台上的車刀桿,刀座與車刀桿再以螺栓固定,替換時只需拆卸刀座部分,相較於整組刀具,刀座重量較輕,替換的時間與難度相對較低。Due to the different processing requirements and the inevitable wear of the blades, the tools often have replacement requirements. The tools are divided into tool holders for mounting the blades and tool holders for mounting on the machine table. The tool holders and the tool holders are bolted. For fixing and replacement, it is only necessary to disassemble the seat part. Compared with the whole set of tools, the holder is lighter in weight and the replacement time and difficulty are relatively low.
然而,習用的固定方式是單純以螺栓鎖固,加工過程中固定螺栓易鬆動,進而造成刀座與車刀桿的相對位置改變,影響加工品質。However, the conventional fixing method is simply bolting, and the fixing bolt is easy to loose during the machining process, thereby causing the relative position of the knife seat and the tool holder to change, which affects the processing quality.
