Description
本發明係一種多軸加工機之加工頭結構方面的技術領域,尤指一種具有可減少損耗以大幅延長使用壽命與加工精密度,以及較具節能效果等功效之多軸加工機之加工頭改良結構者。 The invention relates to the technical field of the structure of the processing head of a multi-axis processing machine, especially an improvement of the processing head of a multi-axis processing machine with the functions of reducing loss, prolonging the service life and processing precision, and having energy saving effects. Structurer.
一般習知多軸加工機之加工頭結構,如圖1至圖3所示,主要係於一輸入軸頭10下方結合有可以一第一中心軸線A為同軸心轉動之一轉接頭11,於該轉接頭11之一側結合有可以一第二中心軸線B為同軸心轉動及移動之一輸出軸頭12。其中該第一中心軸線A與與該第二中心軸線B呈垂直。
Generally, the structure of the processing head of the conventional multi-axis processing machine, as shown in Figures 1 to 3, is mainly combined with an
在第2圖中係指出,當依加工需求欲使該輸出軸頭12旋轉一角度時,需利用該轉接頭11中之油路藉由油壓驅動之方式先使該輸出軸頭12整個向外軸向移動,進而使固定在該輸出軸頭12一側之一第一定位齒盤120脫離固定在該轉接頭11一側之一第二定位齒盤110,使形成允許該輸出軸頭12能於該轉接頭11一側同軸轉動之狀態,而該輸出軸頭12在向外軸向移動之同時,固設在該輸出軸頭12一側之一離合環齒輪121會與固設在該轉接頭
11之一第二傘齒輪111之第二傘齒輪軸112上之一離合齒輪113嚙合,如此該輸入軸頭10中之一輸入軸100便可帶動該轉接頭11之一第一傘齒輪114轉動,然後連動與其嚙合之該第二傘齒輪111轉動,並因此使固設於該第二傘齒輪軸112上之該離合齒輪113隨之轉動,進而驅動與其嚙合之該離合環齒輪121轉動,並因此而可連動該輸出軸頭12旋轉至所需之加工角度。
In Figure 2, it is pointed out that when the
在圖3中係指出,當該輸出軸頭12旋轉至所需之加工角度後,可再利用該轉接頭11中之油路藉由油壓驅動之方式先使該輸出軸頭12整個向內軸向移動,進而使該第一定位齒盤120與該第二定位齒盤110嚙合,以形成不允許該輸出軸頭12於該轉接頭11一側同軸轉動之定位狀態,而該輸出軸頭12在向內軸向移動之同時,該離合環齒輪121會脫離該離合齒輪113,如此該輸入軸100便可帶動該第一傘齒輪114轉動,然後連動該第二傘齒輪111轉動,並使該第二傘齒輪軸112帶動該輸出軸頭12中之一第三傘齒輪122轉動,再連動與該第三傘齒輪122嚙合之一第四傘齒輪123轉動,並因此帶動與該第四傘齒輪123固接之一輸出軸124轉動,而使安裝於該輸出軸124上之一刀具(圖中未示)可對加工件進行切削加工。
It is pointed out in Fig. 3 that after the
然而,由於該輸出軸頭12轉動一角度之前、後,係需先使該輸出軸頭12相對該轉接頭11向外及向內軸向移動以產生離合狀態,而由於該輸出軸頭12係具有相當大的重量,因此在該轉接頭11向外軸向移出一距離時,便會形成懸臂狀態,而其與
該轉接頭11之連結處便需承受非常大的壓力,因此會使其產生非常大的損耗而大幅縮短其使用壽命,尤其是其在損耗之過程中更是會因配合工差加大而影響其加工精密度。而且,利用油壓驅動重量較大之整個輸出軸頭12移動,更是較為耗能。
However, before and after the
