摘 要
槽輪機構(gòu)是一種步進間歇運動機構(gòu),由于結(jié)構(gòu)簡單、制造容易、工作可靠,能準(zhǔn)確地控制轉(zhuǎn)角, 機械效率高, 所以在自動和半自動生產(chǎn)線中得到廣泛的應(yīng)用;但槽輪在銷軸進出槽輪槽口時加速度大,機構(gòu)產(chǎn)生較大的沖擊,而且隨著轉(zhuǎn)速的增加和槽輪槽數(shù)的減少沖擊加劇,因而不適用于高速運轉(zhuǎn)的情況。
本設(shè)計以槽數(shù)4 、銷輪和槽輪中心距33 mm、銷軸半徑2 mm、銑刀半徑2mm 為例,設(shè)計槽槽輪機構(gòu),并對槽輪的運動特性進行分析。采用CAM技術(shù)對槽輪和撥盤進行數(shù)控編程,對零件進行工藝分析,確定刀具和切削用量,最后形成NC指令。

Abstract
Geneva agencies is stepping intermittent movement,because of Simple structure、manufacturing easy、reliable,Can accurately control angle, High mechanical efficiency,Therefore, automatic and semi-automatic production line is widely used; But trough round slot in the round pin and out of the acceleration when Passage,Institutions have a greater impact,moreover, with the speed and the increase in the number of slot groove round of intensified to reduce the impact,Thus does not apply to high-speed operation
My Design is take 4 to trough, and trough round pin round of 33 mm center distance, pin radius of 2 mm, 2 mm radius cutter for example, Design groove grooved wheel agencies, and the movement of tank rounds analysis. Using CAM technology to dial tank round and NC Programming, Process analysis of the parts, Cutting Tool and determine the amount, finally formed NC order.
