【摘要】：隨著機械自動化的發(fā)展,裝配過程的自動化的作用越來越重要。自動化裝配的重要目的是提高生產(chǎn)效率、降低裝配成本、穩(wěn)定與改善產(chǎn)品質(zhì)量、減輕勞動強度以及取代特殊條件下的人工裝配勞動。軸承是機械工業(yè)使用廣泛、要求嚴(yán)格的配套件和基礎(chǔ)件,被人們稱為機械的關(guān)節(jié)。軸承裝配過程中的浪形軸承保持架正反面自動分離這一環(huán)節(jié),目前,仍沒有有效的解決方案,基本上是人工分離,不利于裝配自動化的實現(xiàn)。 為了實現(xiàn)浪形軸承保持架正反面自動分離,以及一些與浪形軸承保持架相類似的具有正反形狀特征的導(dǎo)磁性零件的自動分離,本文設(shè)計了一種新的電磁增強式離心分離裝置,并利用Pro/e軟件對離心分離裝置的各個部件進(jìn)行了建模。其工作原理是離散分單的保持架輸送到離心分離裝置的底盤工作臺上并隨工作臺旋轉(zhuǎn)到磁極下方時,受到慣性離心力、摩擦力和電磁力的作用,由于保持架的正反面形狀不同,使保持架的正反面受到的電磁力大小不同,也就是保持架正反面受到的摩擦力不同。調(diào)節(jié)電機的轉(zhuǎn)速,可以改變慣性離心力的大小。通過比較保持架正反面受到的慣性離心力和摩擦力的大小關(guān)系,實現(xiàn)保持架正反面的自動分離。為了驗證離心分離方法的可行性,利用Pro/E軟件對此裝置的關(guān)鍵部分建模,并導(dǎo)入Ansys有限元仿真軟件中,對保持架正反面受到電磁力的大小進(jìn)行了仿真分析,分析結(jié)果驗證了離心分離裝置的可行性。 離心分離裝置只是初步的開發(fā)設(shè)計,需要更進(jìn)一步的優(yōu)化,這樣才更能保證了軸承自動化裝配過程中的實時性、效率性、經(jīng)濟(jì)性,同時也為一些與浪形軸承保持架相類似的其他零件的正反面自動分離提供了依據(jù)和方法。
[Abstract]:With the development of mechanical automation, the automation of assembly process is becoming more and more important. The important purpose of automatic assembly is to improve production efficiency, reduce assembly cost, stabilize and improve product quality, lighten labor intensity and replace manual assembly labor under special conditions. Bearings are widely used in the mechanical industry, demanding strict accessories and basic parts, known as mechanical joints. At present, there is still no effective solution for the automatic separation of the front and back faces of the wavy bearing cage in the process of bearing assembly, which is basically manual separation, which is not conducive to the realization of assembly automation. In order to realize the automatic separation of the front and back surfaces of the wave bearing cage and some magnetic conductive parts with positive and negative shape similar to the wave bearing cage, a new electromagnetic enhanced centrifugal separation device is designed in this paper. Pro/e software is used to model the components of centrifugal separation unit. The operating principle of the cage is that when the cage is transported to the platform of the centrifugal separator and rotated to the bottom of the magnetic pole with the table, it is subjected to the action of inertia centrifugal force, friction force and electromagnetic force, due to the different shapes of the front and back sides of the cage. The electromagnetic force on the front and back sides of the cage is different, that is, the friction force is different between the front and back sides of the cage. Adjusting the speed of the motor can change the size of the inertia centrifugal force. By comparing the relationship between the inertia centrifugal force and the friction force on the front and back sides of the cage, the automatic separation of the front and back sides of the cage is realized. In order to verify the feasibility of centrifugal separation method, the key parts of the device are modeled by Pro/E software, and the magnitude of electromagnetic force on the front and back sides of the cage is simulated and analyzed by using the Ansys finite element simulation software. The analysis results verify the feasibility of centrifugal separation device. Centrifugal separation device is only preliminary development and design, need further optimization, so as to ensure the real-time, efficiency and economy of bearing automatic assembly process. At the same time, it also provides the basis and method for automatic separation of the front and back surfaces of some other parts similar to the wave bearing cage.
