Description

深孔滾珠螺紋硬式車削加工法及應用其之車床設備Deep hole ball thread hard turning method and lathe equipment using the same

本發明係關於一種加工方法及加工機,尤指一種專用於切削加工出高導程滾珠螺帽內孔中的螺溝的硬式車削加工法及應用其之車床設備。The invention relates to a processing method and a processing machine, in particular to a hard turning method dedicated to cutting and processing a screw groove in an inner hole of a high-lead ball nut and a lathe device using the same.

為提升產業加工生產效率,現今許多CNC工具機之移動檯座,多由可高速移動的線性馬達來驅動。惟,此線性馬達除了價格高昂以外,其精度之控制,需佐以可精密定位之數位編碼感測器(光學尺、磁性尺)來應用,故線性馬達搭配數位編碼感測器之使用,並非最佳高速移動解決方案。而傳統CNC工具機移動檯座的驅動,多係透由滾珠螺帽與螺桿來控制驅動及精密定位。但滾珠螺帽與螺桿其導程未達2倍甚至3倍時,高速移動的效果又不易達成。所以,2倍與3倍高導程的滾珠螺帽與螺桿乃是CNC工具機發展高速移動所需的關鍵。In order to improve the efficiency of industrial processing and production, the mobile pedestals of many CNC machine tools today are mostly driven by linear motors that can move at high speeds. However, in addition to the high price of this linear motor, its precision control needs to be accompanied by a digital encoder sensor (optical ruler, magnetic ruler) that can be precisely positioned. Therefore, the use of a linear motor with a digital encoder sensor is not The best high-speed mobile solution. The driving of the traditional CNC machine tool mobile pedestal is mostly controlled by the ball nut and screw to control the drive and precise positioning. However, when the lead of the ball nut and the screw are less than 2 times or even 3 times, the effect of high-speed movement is not easy to achieve. Therefore, the 2 times and 3 times high lead ball nuts and screws are the key to the development of high-speed CNC machine tools.

滾珠螺帽與螺桿是透過可循環作動的滾珠作為滾動介質,為使滾珠螺帽在螺桿上的運行更為精密與平順,滾珠螺帽內與滾珠所接觸的螺紋珠溝,都會採用熱處理硬化及研磨的工序來提升螺紋珠溝的尺寸精度及幾何精度如圖3所示之研磨工序示意圖,在低導程的滾珠螺帽200研磨加工時,研磨砂輪100還能夠深入滾珠螺帽200。但滾珠螺帽的規格拉到2倍與3倍的高導程規格時,其螺紋珠溝的研磨工序乃無法以傳統的研磨設備來達成,如圖4所揭示之研磨砂輪100,因為輪軸與滾珠螺帽200一端干涉,因此無法以螺紋珠溝的導程角來深入滾珠螺帽200的內孔201來研磨加工。The ball nut and screw are used as rolling media through recirculating balls. In order to make the ball nut run on the screw more precise and smooth, the thread bead groove in the ball nut contacting the ball will be heat-treated and hardened. The grinding process improves the dimensional accuracy and geometric accuracy of the threaded bead groove. As shown in the schematic diagram of the grinding process shown in FIG. 3, when the low-lead ball nut 200 is ground, the grinding wheel 100 can also penetrate the ball nut 200. However, when the specifications of the ball nut are pulled to the high lead specification of 2 times and 3 times, the grinding process of the thread bead groove can not be achieved by traditional grinding equipment, such as the grinding wheel 100 disclosed in FIG. 4 because the wheel shaft and One end of the ball nut 200 interferes, so the lead angle of the thread bead groove cannot be penetrated into the inner hole 201 of the ball nut 200 for grinding.

此外,亦有製造業者採用硬式切削的加工方式來取代研磨工序,使滾珠螺帽加工件先經過粗加工與熱處理硬化之後,直接以CBN(氮化硼)車刀來精密車製螺紋珠溝,其加工方式如圖3及圖4所示,將滾珠螺帽10一端夾設在車牙加工機的夾頭20,另外刀座30固定一刀把40,刀把40前端具有一CBN(氮化硼)刀片50;藉此,控制刀座30移動,將刀把40前端的CBN(氮化硼)刀片50伸入滾珠螺帽10的內孔101,進行螺紋珠溝的切削加工。In addition, some manufacturers use hard cutting to replace the grinding process, so that the ball nut machining parts are first roughened and heat-treated and hardened, and the CBN (boron nitride) turning tool is used to precisely turn the thread bead groove. The processing method is shown in FIGS. 3 and 4. One end of the ball nut 10 is clamped to the chuck 20 of the turning machine. In addition, the tool holder 30 is fixed with a handle 40, and the front end of the handle 40 has a CBN (boron nitride) The blade 50; by this, the movement of the tool holder 30 is controlled, and the CBN (boron nitride) blade 50 at the front end of the tool holder 40 is extended into the inner hole 101 of the ball nut 10 to perform the cutting processing of the thread bead groove.

但是,不論是傳統的車牙加工機或CNC車牙加工機,其刀把40只有後端固定在刀座,刀把40前端(含刀片50)為懸空狀態,若要加工較長的滾珠螺帽,其刀把40的長度更長,因此刀把40的固定點至刀片50的抗力點過長,容易在切削加工時產生刀把40震動,導致切削表面精度不佳、刀具壽命縮短、尺寸誤差擴大等問題。However, whether it is a traditional turning machine or CNC turning machine, only the rear end of the tool holder 40 is fixed to the tool holder, and the front end of the tool holder 40 (including the blade 50) is in a suspended state. If you want to process a longer ball nut, The length of the handle 40 is longer, so the fixed point of the handle 40 to the resistance point of the blade 50 is too long, and the vibration of the handle 40 is easily generated during cutting, resulting in poor cutting surface accuracy, shortened tool life, and enlarged dimensional errors.

此外,上述兩種方式的車牙、鑽孔等加工作業,皆以CNC方式進行,因此在螺母素材裝上加工機上後,必須花很長的時間予以校準,否則會有精確度的問題,又是增加了作業困難度與完成時間。是以,傳統螺母素材的加工方式,具有生產機台成本昂貴、整體加工作業時間較長、精確度欠佳,或耗費很多校準時間等問題。上述習知技術的諸多缺失,應設法予以排除。In addition, the above two methods of machining operations such as turning and drilling are carried out by CNC. Therefore, after the nut material is installed on the processing machine, it must take a long time to calibrate, otherwise there will be accuracy problems. It also increases the difficulty of the job and the completion time. Therefore, the processing method of traditional nut materials has the problems of high production cost, long processing time, poor accuracy, or a lot of calibration time. Many defects of the above-mentioned conventional techniques should be eliminated.
