Description
本發明係有關於一種回轉軸結構，尤指一種容易調整至無間隙傳動之凸輪式雙回轉軸結構。 The present invention relates to a rotary shaft structure, and more particularly to a cam type double rotary shaft structure that is easily adjusted to a gapless transmission.
請由第5圖所示，習知之滾齒凸輪等凸輪機構係具有一轉塔60，該轉塔60於外緣鎖結有複數個從動輪61，從動輪61並呈輻射狀之等間距排列，又且該轉塔60係配合使用有一凸輪70，轉塔60與凸輪70並均安裝在一殼座80中，使當凸輪70旋轉時，從動輪61將受到凸輪70之限制與推動，而令轉塔60得以隨著凸輪70旋轉，藉此達到加工使用之目的，但詳觀上述習知結構不難發覺其尚存有些許不足之處，主要原因係歸如下：由於使用單一驅動源帶動單一轉塔60之設計，逐漸的無法滿足需要大量生產之使用需求，但若置放多台凸輪機構，則會延伸有佔據空間、同步性差與額外增加操作人員等缺失，因此將複數個轉塔整合呈單一機台就有其必要性，由於該凸輪機構非常重視齒合精密度，即凸輪70與轉塔60之間的無間隙傳動效果，此部份將會造成整合上之執行困難度，使得業界長期以來無法製造出整合複數轉塔之凸輪機構，此為本創作所欲改善之技術問題點。 As shown in FIG. 5, a conventional cam mechanism such as a hobbing cam has a turret 60, and the turret 60 is locked with a plurality of driven wheels 61 at the outer edge, and the driven wheels 61 are arranged at equal intervals in a radial shape. Moreover, the turret 60 is used in conjunction with a cam 70, and the turret 60 and the cam 70 are both mounted in a housing 80 so that when the cam 70 rotates, the driven wheel 61 will be restrained and pushed by the cam 70. The turret 60 can be rotated with the cam 70 to achieve the purpose of processing, but it is not difficult to find out that the above-mentioned conventional structure has some shortcomings, mainly due to the following: due to the use of a single driving source The design of a single turret 60 is gradually unable to meet the needs of mass production. However, if multiple cam mechanisms are placed, there will be a lack of space, poor synchronism and additional operator shortages, so multiple turrets will be used. It is necessary to integrate a single machine. Since the cam mechanism attaches great importance to the precision of the teeth, that is, the gapless transmission between the cam 70 and the turret 60, this part will cause difficulty in integration. Make the industry Since the cam mechanism of integration can not create complex turret of this problem desired improvement technology-based creation.

The driven helical gear 53 and the reduced helical gear 55 are performed The gap between the helical gears 51 (52) (53) (55) can be adjusted in the axial displacement direction in the state of having a gap, thereby not only achieving easy adjustment to the gapless transmission state, but also The adjustment is completed without affecting the gapless transmission of the first and second turret 10 (20) and the first second worm 30 (40), so as to drive the first and second turrets 10 (20) in a single driving source. In the case of a gapless transmission.
