TY295柴油機機體三面鉆孔組合機床總體及左主軸箱設計
摘要：由于TY295柴油機使用的廣泛性，該型號柴油機機體是需要大批量生產(chǎn)的。為提高其加工精度和生產(chǎn)效率，需要設計一臺組合機床來改善柴油機機體的加工情況。本課題是針對TY295柴油機機體三面鉆孔組合機床總體及左主軸箱的設計，用于同時加工被加工零件左側面上的15個 孔，3個 孔；右側面上7個 孔，3個 孔，5個 孔；后面上的3個 孔，一個 孔，一次裝夾同時完成37個孔的加工。
在設計過程中，采用后面、左面、下面三面定位, 左面和后面用定位銷定位，下面用定位條定位。上面采用氣壓缸夾緊, 加工工藝性較好,零件裝夾方便。此次設計主要分為組合機床總體設計和左主軸箱設計兩大部分，在進行這兩塊設計時，首先需要確定切削用量，計算切削力、切削扭矩、切削功率及刀具耐用度，然后以此確定主軸、外伸尺寸等。對于主軸箱設計部分，首先需要繪制設計原始依據(jù)圖，并進行主軸、齒輪的確定與動力計算，接著進行主軸箱的動力計算等，最后，還需進行齒輪、各類軸的校核，就此完成了整個設計過程。此次設計采用臥式單工位三面同時鉆孔的方案，這是設計的亮點，能夠大大節(jié)約加工時間，提高工作效率。同時本組合機床有結構簡單、操作方便、加工精度高、工人勞動強度低及有利于提高加工生產(chǎn)率等優(yōu)點，實現(xiàn)了設計的目標要求。

Design of General and Left Headstock of Modular Machine Tool for Drilling Holes on Three-Side of TY295 Diesel Engine Block
Abstract: Due to the extensive use of TY295 diesel engine. It is a product which needs of mass production. In order to prove the disposition and the production efficiency, we need to design a high effective modular machine tool to improve the production of the TY295 Diesel Engine Block. This issue is a design of TY295 engine block for drilling on three sides and left the overall combination of machine tool spindle box. This used for cure the holes of Three-Side of TY295 Diesel Engine Economy at one time, left face of fifteen holes with the diameter is 6.8, 3 holes with the diameter is 8.5; the right side surface of seven holes whit the diameter is 6.8, three holes with the diameter is 8.5, 5 holes whit the diameter is10.3; behind side surface of the 3-holes with the diameter is 12, a hole with the diameter is 14.
The modular machine tool uses the horizontal-type single location three-side processing plan, the processing and assembly technology capability is good, and it clamps conveniently. In the design process of jig, the work piece has been located by three surfaces - behind, left and underside. A pin has been used on the behind and left. Two orientation bars have been used on the underside. Use pneumatic cylinder to clamp the above and the right side. On the compress platen，using a guide rod to guide clamping, in order to make it clamping smooth and reliable. This design included the design of machine tool and the headstock of left.I need to determine the cutting parameters to calculate the cutting force, torque, power and tool life, and then to determine the axis size outriggers first. For the Part of the spindle box design, we should draw the picture, count the principal axis and the gear, the drive of headstock. At last, we must check these. This modular machine tool has many advantages such as the simple structure, the ease operation, the high processing precision , the worker labor intensity is low and is advantageous to raise the production efficiency and so on.
