The two flexible absorbers 30 are respectively disposed between the two end walls 13 and the two end faces 22. The at least one flexible damping adjustment member can be increased in number according to actual needs. Preferably, the plurality of flexible damping adjustment members 40 are disposed in the figure, and the plurality of flexible damping adjustment members 40 are radially disposed on the peripheral wall 12 and The circumferential surface 21 is axially disposed between the end wall 13 and the two flexible absorbers 30.

較詳細地說，該桿體10之一端另設有一刀頭14，該刀頭14例如為車刀、銑刀、搪刀或其他切削刀具。In more detail, one end of the rod body 10 is further provided with a cutter head 14, such as a turning tool, a milling cutter, a file or other cutting tool.

各該撓性吸收件30之撓性小於該端壁13之撓性且大於該撓性阻尼調整件40之撓性，藉此，該複數撓性阻尼調整件40之一部分獲得足夠的軸向支持且能有效的吸收軸向震動，並可避免較軟的撓性阻尼調整件40受較硬的該桿體10與該阻尼器20壓輾而損壞。較佳地，各該撓性吸收件30係為塑件，例如：優力膠、乙烯龍，上述材料常用於工具機領域，但凡具有易於加工且撓性介於該桿體10與該撓性阻尼調整件40之間者，皆可用作該撓性吸收件30的材料。The flexibility of each of the flexible absorbing members 30 is less than the flexibility of the end wall 13 and greater than the flexibility of the flexible damper adjusting member 40, whereby a portion of the plurality of flexible damper adjusting members 40 obtain sufficient axial support. Moreover, the axial vibration can be effectively absorbed, and the soft flexible damping adjusting member 40 can be prevented from being damaged by the hardened rod 10 and the damper 20. Preferably, each of the flexible absorbing members 30 is a plastic member, such as: superior rubber, vinyl dragon, the above materials are commonly used in the field of machine tools, but the ease of processing and flexibility between the rod 10 and the flexibility Any of the damper adjustment members 40 can be used as the material of the flexible absorbing member 30.

各該撓性吸收件30徑向上與該周壁12具有一間隙15。較佳地，該間隙15不大於該撓性吸收件30之厚度的五分之一。該撓性吸收件30受到軸向力壓縮時會產生徑向形變，該間隙15可避免該周壁12限制了該撓性吸收件30徑向形變，影響該撓性吸收件30的吸震效果或造成該撓性吸收件30損壞。Each of the flexible absorbing members 30 has a gap 15 with the peripheral wall 12 in the radial direction. Preferably, the gap 15 is no more than one fifth of the thickness of the flexible absorbent member 30. The flexible absorbing member 30 is radially deformed when subjected to axial force compression, and the gap 15 prevents the peripheral wall 12 from restricting the radial deformation of the flexible absorbing member 30, affecting the shock absorbing effect of the flexible absorbing member 30 or causing The flexible absorber 30 is damaged.

較佳地，該阻尼器20為柱狀，該複數撓性阻尼調整件40包括至少一第一撓性阻尼調整環41，該周面21設有至少一環槽23，該至少一第一撓性阻尼調整環41套嵌於該周面21之至少一環槽23。在本實施例中，該周面21之二端分別設有四該環槽23，各該環槽23套嵌有一該第一撓性阻尼調整環41，然配置數量並不限。Preferably, the damper 20 is columnar, and the plurality of flexible damping adjustment members 40 include at least one first flexible damping adjustment ring 41. The circumferential surface 21 is provided with at least one annular groove 23, the at least one first flexible The damping adjustment ring 41 is fitted in at least one annular groove 23 of the circumferential surface 21 .

The second flexible damping adjusting ring 42 is respectively embedded in the two flexible absorbing members 30, and the at least two second flexible damping adjusting rings 42 are fixed to the damper. The position of the concentric 20 reduces the radial displacement of the second flexible damping adjustment ring 42 to affect the damping effect. Preferably, the outer diameter of each of the second flexible damping adjusting rings 42 is smaller than the radial dimension of the peripheral wall 12 to facilitate installation and avoid limiting the radial deformation of the second flexible damping adjusting ring 42 so as to fully exert its The impact effect; the ring section of the second flexible damping adjusting ring 42 is not larger than the ring body section of the first flexible damping adjusting ring 41, and the smaller ring body section makes the end wall 13 and the two flexible absorbing members The spacing between the 30s is small, so that the coolant flowing into the ineffective space through the through holes through the processing is less in the processing and the flow is smoother. In more detail, the two ends of the rod body 10 are respectively provided with a through hole 16 , and the damper 20 is axially disposed with a through hole 24 . Each of the flexible absorbing members 30 is provided with a through hole 31 , the through hole 24 and the two through holes . 16,31 connected. Thereby, the cooling liquid can flow through the through holes 16, 31 and the through hole 24 through the cutter head 14 during processing to achieve the function of lowering the temperature and removing the chips at the processing place.

綜上，本創作於該阻尼器之徑向及軸向上配置該複數撓性阻尼調整件以及該等撓性吸收件，可達到刀桿軸向及徑向較佳的減震效果。In summary, the plurality of flexible damping adjusting members and the flexible absorbing members are disposed in the radial direction and the axial direction of the damper to achieve a better damping effect in the axial direction and the radial direction of the arbor.
