現有一種加工機主軸頭(台灣證書號數第M483840號專利案的先前技術)，包含一90度側銑頭、一分度模組、一抓取模組與一主軸頭，其中該主軸頭提供該90度側銑頭的動力來源，該抓取模組懸吊該90度側銑頭，該分度模組讓該90度側銑頭擁有360度轉動的能力，且該90度側銑頭可與該主軸頭結合，以接收該主軸頭的動力輸出。 There is an existing processing machine spindle head (the prior art of Taiwan Patent No. M483840), which includes a 90-degree side milling head, an indexing module, a grasping module and a spindle head, wherein the spindle head provides The power source of the 90-degree side milling head, the grasping module suspends the 90-degree side milling head, the indexing module allows the 90-degree side milling head to have the ability to rotate 360 degrees, and the 90-degree side milling head It can be combined with the spindle head to receive the power output of the spindle head.

該90度側銑頭為具有相當重量的機械結構，其最重可達200~300公斤，為了運作時的安全性，一般會使用分度夾持機構來夾持該90度側銑頭，分度夾持機構包含設於該抓取模組與該90度側銑頭之間的複數齒型離合器與設於該分度模組上的複數油壓缸，並利用該複數油壓缸之壓力由下朝上推移該90度側銑頭與該抓取模組靠近，以讓該複數齒型離合器接合定位在一起。而當該分度 模組要帶動該90度側銑頭轉動時，需要讓該複數齒型離合器鬆脫，以讓該90度側銑頭藉由重量的自重而下移，此時該分度模組即可帶動該90度側銑頭轉動至所需方向，而當轉向完成之後，該複數油壓缸會再次施壓，以藉由該複數油壓缸之壓力推移該抓取模組與該分度模組靠近，而讓該複數齒型離合器接合定位在一起。 The 90-degree side milling head is a mechanical structure with a considerable weight, and its heaviest weight can reach 200-300 kg. For safety during operation, an indexing clamping mechanism is generally used to clamp the 90-degree side milling head. The degree clamping mechanism includes a plurality of tooth clutches arranged between the grasping module and the 90-degree side milling head and a plurality of hydraulic cylinders arranged on the indexing module, and utilizes the pressure of the plurality of hydraulic cylinders Push the 90-degree side milling head from bottom to top to approach the grabbing module, so that the plurality of tooth clutches are engaged and positioned together. And when the index When the module wants to drive the 90-degree side milling head to rotate, it is necessary to loosen the multiple tooth clutches so that the 90-degree side milling head can move down by its own weight. At this time, the indexing module can drive The 90-degree side milling head rotates to the desired direction, and when the steering is completed, the multiple hydraulic cylinders will apply pressure again, so as to push the grasping module and the indexing module by the pressure of the multiple hydraulic cylinders close to allow the plurality of tooth clutches to be engaged and positioned together.

為供進一步瞭解本發明各元件配合所產生的作用、運用技術手段，以及所預期達成的功效，將再說明如下，相信當可由此而對本發明有更深入且具體的瞭解。 In order to further understand the functions produced by the cooperation of the various components of the present invention, the technical means used, and the expected effects, the following will be described again, and it is believed that a deeper and specific understanding of the present invention can be obtained from this.

如圖2及圖3所示，當整體組配完成，且顯示該活塞件33位於一上昇位置，該定位離合器30的內冠齒環31、外冠齒環32同時與該下冠齒環34互相咬合，該軸頭單元20相對於該基座單元10產生定位，且該軸頭座23相對於該基座單元10呈靜止不動。此時，因為該上轉盤21的凸環211伸設於該環槽15中，且使該上轉盤21限位於該上擋環125與該頂壁11之間且可轉動地被支撐於該上擋環125上，且使該基座單元10承托該軸頭單元20的重量，確保該下冠齒環34相對於該內冠齒環31與該外冠齒環32產生較佳的咬合效果。且壓力源只需對該活塞件33產生作用，不會受到該軸頭單元20 的重量作用而影響該下冠齒環34相對於該內冠齒環31與該外冠齒環32的咬合力。 As shown in Fig. 2 and Fig. 3, when the overall assembly is completed, and the piston member 33 is shown in a raised position, the inner crown tooth ring 31 and the outer crown tooth ring 32 of the positioning clutch 30 are simultaneously connected with the lower crown tooth ring 34 Interlocking with each other, the shaft head unit 20 is positioned relative to the base unit 10 , and the shaft head seat 23 is stationary relative to the base unit 10 . At this time, because the protruding ring 211 of the upper turntable 21 is extended in the ring groove 15, and the upper turntable 21 is limited between the upper stop ring 125 and the top wall 11 and is rotatably supported on the upper stop ring 125. on the retaining ring 125, and make the base unit 10 support the weight of the shaft head unit 20, so as to ensure that the lower crown tooth ring 34 has a better bite effect with respect to the inner crown tooth ring 31 and the outer crown tooth ring 32 . And the pressure source only needs to act on the piston member 33 and will not be affected by the shaft head unit 20 The effect of weight affects the occlusal force of the lower crown tooth ring 34 relative to the inner crown tooth ring 31 and the outer crown tooth ring 32 .

再如圖4及圖5所示，當要進行分度定位時，在該基座單元10呈靜止的狀態下，可啟動一壓力源(圖未示)，並使壓力源進入該缸室25中，並驅動該活塞件33朝下位移，此時，該活塞件33位於一下降位置，且使得該定位離合器30的下冠齒環34相對於該內冠齒環31與該外冠齒環32在一分離位置，該定位離合器30呈分離的狀態，因此，當透過外力(非本發明論究的重點且圖未示)帶動該軸頭座23相對於該基座單元10產生分度調整，利用該軸承件40設置於該基座單元10的上擋環125與該軸頭單元20的凸環211之間，則可提供該軸頭單元20相對於該基座單元10順暢轉動。最後透過該等刻度131相對於該指標231(配合參圖1)，就可得知該軸頭座23的轉動角度。且分度調整後，再啟動壓力源，並使壓力源驅動該活塞件33上移，且回復成圖2與圖3所示的狀態，該定位離合器30的該下冠齒環34同時再與該內冠齒環31、該外冠齒環32互相咬合，該軸頭單元20又相對於該基座單元10產生定位。 As shown in Fig. 4 and Fig. 5 again, when indexing and positioning are to be performed, when the base unit 10 is in a static state, a pressure source (not shown) can be activated, and the pressure source enters the cylinder chamber 25 , and drive the piston member 33 to move downwards. At this time, the piston member 33 is in a descending position, and makes the lower crown tooth ring 34 of the positioning clutch 30 relative to the inner crown tooth ring 31 and the outer crown tooth ring 32 is in a disengaged position, and the positioning clutch 30 is disengaged. Therefore, when an external force (not the focus of the present invention and not shown in the figure) drives the shaft head seat 23 to produce indexing adjustment relative to the base unit 10, The bearing 40 is disposed between the upper stop ring 125 of the base unit 10 and the protruding ring 211 of the shaft head unit 20 , so that the shaft head unit 20 can rotate smoothly relative to the base unit 10 . Finally, through the scales 131 relative to the index 231 (with reference to FIG. 1 ), the rotation angle of the shaft head seat 23 can be known. And after index adjustment, restart the pressure source, and make the pressure source drive the piston 33 to move upwards, and return to the state shown in Figure 2 and Figure 3, the lower crown tooth ring 34 of the positioning clutch 30 is simultaneously with the The inner crown gear ring 31 and the outer crown gear ring 32 are engaged with each other, and the shaft head unit 20 is positioned relative to the base unit 10 .
