毕业设计（论文）-六工位回转工作台设计.docVIP

摘 要 六工位回转工作台式组合机床为广东省东莞力达公司（美国通用电气公司）专门设计制造的，用于加工电机前后端盖六工位回转工作台式组合机床。在本机床完成上料、粗镗、钻孔、攻丝、精镗止口、下料六工序，生产节拍20 秒钟。该六工位回转工作台是采用了比较简单的换位斜板和转向盘来实现转位和定位，换位斜板与燕尾形导轨的滑块相连，用气缸推动，换位斜板只能沿导轨作直线运动。 换位斜板是一块多边形，在转向盘底下均匀地分布着一些圆柱定位销，其数量等于分度工位数。当拟制活塞推动斜板向前移动时，斜板的一边推动着定位销，使转向盘回转。转到极限位置时，压缩气体进入拟制的另一腔，使活塞杆带动斜板向后退回。六工位回转工作是该机床的重要组成之一，它对工件的加工精度有直接的影响。主要是它的定位精度对工件精度影响很大。还有是否有可靠的固定，使加工时工作台能平稳。工作台旋转的快慢，影响机床的工作效率。冲击的大小又直接影响产生的噪音。所以在设计过程中，即要考虑机床的工作效率，准确的工作定位，冲击又不能太大，以免产生太大噪音，影响居民的工作和休息。 关键词： 六工位；回转工作台；换位斜板 Abstract Six works turn round work set type combination machine bed as what theprovince Dong Guan dint of Guangdong reach the specialized design incompany (in general use electricity in the United States company)manufacturing, used for processing the electrical engineering to carry to cover infront and back six works turn round the work set type combines the machine bed.Anticipate in this machine bed completing, heavy boring, drill a hole, offend the silk, right boring, descend to anticipate six work preface, produce 20 seconds in rhythm.The six-position rotary table is used relatively simple to board and Zhuanxiang Pan-ramp to achieve transfer and positioning, and transfer oblique plate-shaped Dovetail zoned plate connected to the rails, with the cylinder topromote, transfer only oblique plate Can make straight-line movement along the rails.Transposition is a polygon inclined board, in Zhuanxiang Pan evenlydistributed under a number of cylindrical pin, the number of points equal to the median. When drawing up the ramp to promote the Pistons board move forward,the ramp side of the plate to promote the pin, so that Zhuanxiang Pan Rotary. Tolimit location, compressed gases into the preparation of another cavity, the roddrivenbackward inclined to return. Six works an importance for turning round work is the machine bedsconstitute it, it to work an influence for processing accuracy having directly.Primarily is fixed position accuracy that work efficiency that it to work a rate of speed for
