The utility model relates to a vibration reducing tool seat for machining double row cylindrical roller bearing oil groove on a numerical control lathe. The utility model is characterized in that the clamping seat comprises a clamping seat, an outer diameter tool clamping position and a boring tool clamping position, and the clamping seat is located at the center of the clamping face on both sides of the outer diameter tool clamping position and the clamping position of the boring tool clamping position, and the clamping position of the outer diameter tool clamping and the boring tool clamping position. At least three locking screw holes are arranged on both sides of the position, the suspension length is 100_, and the front of the clamping position of the boring cutter is inclined to the horizontal plane of the clamping seat at 30 degree. The utility model has the advantages of fixed clamping and rigid structure, which can not only avoid the vibration of the cutter rod, but also ensure the center high position of the clamped cutter and reduce the wear of CBN cutter blade; the boring cutter position is optimized with a 30 degree inclination angle, which is beneficial to the reverse boring cutter, reduces the weight of the cutter tower and can be used for hanging up to 150 mm hard lathe. It is necessary to complete four oil trench processing at one time and improve the production efficiency.

一种数控车床加工双列圆柱滚子轴承油沟用减振刀座
本技术涉及一种数控车床加工双列圆柱滚子轴承油沟用减振刀座,特别是适用于GS250数控车床硬车带双挡边的双列圆柱滚子轴承油沟,属轴承加工
技术介绍
轴承行业采用GS250数控车床硬车带挡边的圆柱轴承外圈油沟,一般采用镗孔刀杆加35°菱形CBN刀片在数控车床上成形加工而成,对于GS250机床的标准VDI-40刀塔,最大装夹Φ40mm镗孔刀,该镗孔刀悬长超过80mm,硬车油沟时,刀杆就会出现剧烈振动、啸叫,采用的CBN刀片出现剧烈磨损甚至崩坏想象;同时,采用标准镗孔刀硬车油沟只能二次装夹双列圆柱滚子轴承工件才能完成四个油沟加工,效率低下。
技术实现思路
本技术的目的是提供减少悬伸过长的系统振动,降低CBN刀片磨损,可用于悬长达150mm,且能提高工作效率的一种数控车床加工双列圆柱滚子轴承油沟用减振刀座。本技术采用如下技术方案:一种数控车床加工双列圆柱滚子轴承油沟用减振刀座,其特征在于它包括装夹座、外径刀装夹位和镗孔刀装夹位,装夹座位于外径刀装夹位和镗孔刀装夹位的两侧装夹面的中心位置,外径刀装夹位和镗孔刀装夹位的两侧至少均 ...
