Description
本創作係涉及一種機床零件，尤其是指一種能對應加工震動的大小來調整吸收震動之能力的可微調整之減震攻牙刀桿。 This creation relates to a machine tool part, in particular to a micro-adjustable shock-absorbing tapping tool bar capable of adjusting the ability to absorb vibrations corresponding to the size of the machining vibration.
如圖7所示的一種現有減震刀桿90，其包括有刀桿本體91、緩衝塊92、筒夾固定件93、夾制組94、筒夾95、刀具96及固定蓋97；其中，刀桿本體91具有相對的二端且包括有容置孔911及定位槽912，容置孔911由刀桿本體91的其中一端朝向刀桿本體91的另一端軸向延伸，定位槽912軸向銜接容置孔911，緩衝塊92容置於定位槽912且係採用具有撓性的材質製成，筒夾固定件93穿置於容置孔911且抵靠於緩衝塊92，夾制組94固結於刀桿本體91且包括有複數個夾制件941，夾制組94以所設的夾制件941來夾制筒夾固定件93，筒夾95穿置於筒夾固定件93，刀具96穿置於筒夾95，固定蓋97鎖固於筒夾固定件93且抵靠於筒夾95； 現有的減震刀桿90利用具可撓性的緩衝塊92來吸收加工時所產生的震動，因此具有加工較為細緻、噪音較小與刀具使用壽命較長等優點；然而單一設置的緩衝塊92難以針對實際的加工情況來作細部調整，無法對應螺紋的規格來改變刀桿吸震程度；再者，現有減震刀桿90的緩衝塊92通常採用優力膠來製作，由於優力膠製成的緩衝塊92直接吸收震動的力量，在經過一段時間後容易變質、硬化而降低緩衝效果；由此可知，現有的刀桿在吸收震動的設計上仍有改善的空間。 As shown in FIG. 7 , a conventional damper blade 90 includes a shank body 91 , a buffer block 92 , a collet fixing member 93 , a clamping group 94 , a collet 95 , a cutter 96 , and a fixing cover 97 .

The cutter 96 is placed in the collet 95, the fixing cover 97 is locked to the collet fixing member 93 and abuts against the collet 95; The prior art damper bar 90 utilizes a flexible buffer block 92 to absorb the vibration generated during processing, thereby having the advantages of relatively fine processing, low noise, and long tool life; however, a single set of buffer blocks 92 It is difficult to make detailed adjustments for actual machining conditions, and it is impossible to change the degree of shock absorption of the cutter bar according to the specifications of the thread; in addition, the buffer block 92 of the existing shock absorbing cutter bar 90 is usually made of superior glue, which is made of superior glue. The buffer block 92 directly absorbs the vibration force, and is easily deteriorated and hardened after a period of time to reduce the buffering effect; thus, it is known that the existing cutter bar still has room for improvement in the design of absorbing vibration.
