摘要：
本課題主要完成立式磨簧機的設計，為滿足彈簧業(yè)批量生產(chǎn)彈簧需求而設計。為提高磨削效率，減少裝工件的次數(shù)和時間，把磨簧機設計成雙面磨，即用兩個砂輪同時對彈簧的兩個端面進行磨削。先根據(jù)磨簧機的功能確定磨簧機的總體結(jié)構(gòu)，為砂輪在磨削時實現(xiàn)進給運動和滿足不同高度彈簧的磨削要求，砂輪必須實現(xiàn)軸向移動。為簡化結(jié)構(gòu)，只要一磨頭實現(xiàn)進給，另一個磨頭固定。綜合各種因素，確定把下磨頭固定，不實現(xiàn)進給，上磨頭實現(xiàn)進給運動。
在結(jié)構(gòu)上磨頭實現(xiàn)自動進給、復位。降低了工人的勞動強度，改善了工人勞動條件。工人可以同時操作多臺磨簧機，提高了生產(chǎn)力。在卸料上實現(xiàn)工件的自動卸料。解放工人的雙手，進一步提高了工作效率。砂輪經(jīng)過長時間磨削產(chǎn)生損耗，會引起彈簧加工精度的下降，該磨簧機在結(jié)構(gòu)上實現(xiàn)了砂輪的補償，磨削精度得到了保障。
設計的該磨簧機自動化程度高、磨削效率高，工人勞動強度低，結(jié)構(gòu)緊湊，占地面積小，有效地利用了廠房空間。本次設計在滿足工作可靠，結(jié)構(gòu)簡單等要求下，盡量使用了通用部件，降低了制造成本。

Abstract: To meet the needs of volume mass spring production , this topic mainly completes the vertical spring grinding machine design, In order to enhance the grinding efficiency, and reduce the work piece the number of install times , I designed the spring grinding machine which doubling surface to rub, namely carries on the grinding with two grinding wheels at the same time to the spring two end surfaces. Acts according to first the spring grinding machine function to determine spring grinding machine overall structure, for grinding wheel when grinding realizes the feed motion and satisfies the different spring the grinding request, the grinding wheel must realize the end motion highly. In order to simplify the structure, so long as a grinding realization to feed, another grinding is fixed. Synthesizes each kind of factor, determined is fixed under grinding, does not realize to feed, on grinding realization feed motion.
In structure grinding realization auto-feed, replacement. Reduced worker's labor intensity, improved the worker work condition. The worker may concurrent operation multi-Taiwan rub the reed machine, enhanced the productive forces. Realizes the work piece self-dumping on the ex-denning. Liberates worker's both hands, further enhanced the working efficiency. The grinding wheel passes through the long time grinding to be able to have the batardeau to consume, can cause the spring processing precision drop, should rub the reed machine to realize the grinding wheel compensation in the structure, the processing precision has been high.
The machine has high automaticity high and the grinding efficiency, the workers labor intensity is low, the structure is compact, the area is small, the workshop space effectively is used. This design satisfies the demands of relable, structure simple and so on , the general part are used as far as possible, the production cost is reduced.
