The key slot high-efficiency processing equipment of the utility model includes a frame, a slotting tool, a traction mechanism for pulling a slotting tool on the frame, and an installation part for installing the workpiece. The installation part is fixed on the frame, located outside the front end of the frame, and consists of two fixtures on both sides of the slotting hole. The front end of the frame is provided with a workpiece support bench under the installation part, and the workpiece support bench is arranged above the workpiece support bench. The workpiece support block moves up and down relative to the workpiece support platform through a hydraulic mechanism or a screw mechanism; a socket sleeve for adjusting the position and feed of the cutter is also provided when the keyway is processed efficiently; and the upper edge of the cutter head is set to be front, low and back high. The installation part of the utility model has simple structure, is combined with workpiece support platform and workpiece support block, is convenient for fixing workpiece, and the design of slotting sleeve solves the problem that the matching between broach and workpiece can not be adjusted when the existing technology is used for continuous slotting of broach, and the processing efficiency of keyway is greatly improved in practical application.

键槽高效加工设备
本技术涉及机加工,具体是键槽高效加工设备。
技术介绍
键槽加工常采用的方法是将夹具加工成一个整体固定在拉床上,将拉刀于夹具拉槽中移动,完成拉键槽作业。CN204122838U的专利公开了一种曲轴齿轮键槽加工机构,包括齿轮夹具、拉刀和牵引装置,拉刀通过牵引装置与拉床的拉轴固定连接,拉刀穿过齿轮夹具中心,所述齿轮夹具包括固定在拉床上的夹具体,夹具体上固装有齿轮定位轴,在所述夹具体上还固定有对曲轴齿轮周向定位的销轴定位装置;该销轴定位装置固定在拉刀槽的左上方。CN201720446138的键槽加工机,包括机架、拉刀、设置在机架上牵引拉刀的牵引机构、固定在机架上用于安装齿轮的安装部,其与CN204122838U的不同在于所述机架上还设置一清理组件,所述清理组件包括毛刷、驱动毛刷沿拉刀刀槽方向移动的驱动件;在进行键槽加工的同时通过毛刷对拉刀的刀槽进行清理。工作的时候,将拉刀自第二插槽插入,将连接件自第一插槽插入,从而固定拉刀,将齿轮套在支撑杆上,启动油缸带动拉刀移动加工齿轮上的键槽;在拉刀移动同时,气缸带动毛刷对刀槽进行清理,在拉刀从齿轮脱离的时候,油缸继 ...
