XX( )4.4AbstractPolishing machine is a kind of important precision and ultra precision machining method. It refers to the process of using a tool to make the micro machining process through the surface of the workpiece. The machining accuracy and quality of the polishing machine. Therefore, the polishing machine is an important condition to guarantee the machining of the polishing machine. At present, there are many factories in the domestic production of high speed polishing machine, but because of the strong pertinence of the polishing machine, the method of polishing machine is very different.Ring polishing machine is a special machine tool, the machine can process parts. In order to improve the overall quality of the whole process, a new type of high precision machining precision machining machine is developed based on the deep analysis of the original machine. The machine controls the movement of the research with the two part of the power source. The whole drive system is analyzed, and the transmission is designed. On the basis of the design of the various parts, the overall structure layout. The new machine overcomes some of the shortcomings of the original machine, and has improved the efficiency and accuracy of the transmission. This design is based on the original foundation to improve the production efficiency. The machine tool has the characteristics of high precision, stable performance and high productivity.Key words: polishing machine, mechanical transmission, upper and lower material (I)Abstract (II) (III)1 (1)1.1 (1)1.2 (1)1.3 (2)1.4 (3)2 4.4 (5)2.1 (5)2.2 (5)2.2.1 (5)2.2.2 (6)2.2.3 (6)3 4.4 (8)3.1 (8)3.2 (9)3.2.1 (9)3.2.2 (10)3.2.3 (10)3.2.4 (11)3.2.5 (13)3.2.6 (13)3.2.7 (13)3.3 (16)3.4 (16)3.5 (18)3.6 ( ) (20)3.7 (21)3.8 (22)4 (23)4.1 (23)4.1.1 (23)4.1.2 (23)4.2 (24)4.3 (25) (28) (29)11.1PLC1.22MM8470 ZML CYJ-1DF_4 ADAMS UG X61 1112K-1 Cag One 1—4 1.31.41 m2 m 2.5 m 800 mm 800 mm 4.4m 1600 mm4.4m 1.5m 0~4 r/min1.8m 2m 0~8r/min0-120°1.5mA0 21 ”152 4.42.12.22.2.1(1)(2)(3)2.2.21:1300-500r/min DSP DSP , , , , , PWM , ,PID , PID PID2.2.31:1PID3 4.43.157 24V 24V :n=30r/min f=100HZ57BYJ250C3.23.2.13-13.2.2f=0.2mm/r v=18m/min 0.28KW=0.75°,=0.005mm/p3.2.31 .. . 5-1 ,2 ., , .. . 5-2 ,2. . 5-3 ,3.2.40.03 K 1.1~1.5 1.3N G F G G G G G F F G f KF F Z x 215522-)22(03.03.122-)22(3y 13323y max 0min F 21t t 122n nN t n t n t n F t n F F m 1494(312211223min 113max 316m h k a h t wm 1060)nT (f f f f f F C ar f w ------- f w =1.2f t -------- f t =1f h ------- f h =1f a ------- f a =1f k ------- f k =1F m ------n z -------T h ---------- 15000hC ar =17300N40mm, 5mmC a =C ar =17.3KN,C oa =(2~3)F m 34.6~51.9 KNP h =12mmFFZD FFZD4010—31D 10(0.2~0.255)b D d d 30.7mm3.2.5 )(tg tg =10’0'0''433()(43310)0.96g g g g t t t t3.2.6ESFl l 01(cm) 60622221.651261251.820.5120.610 2.141252.6210.520.610(/)3.14() 2.146.1210Y F Nl cmE N CM S R CM L CM06410010010.56.121012.241012.24[]l L um[ ]=15 m/m3.2.71 . .. 5-4 le=20 mmL u =210+120+20=350mm L v =350-20=330mm2 .e p =0.01/300×350×103=11.7 . 5-5T34, , . ,. 5-6 , (F-S) .5C C jC j=[(F e f w)/(f h f t f a f k)]×[(60L h n e)/(106)]1/3C j-- (N)F e-- (N) .F e=(120+0.06×120)/2=63.6Nn e-- (r/min). n e=250r/min.L h-- (h). ..5-7 L h=15000 h.f t-- . ..5-8, f t=0.70.f a-- . ..5-9 f a=1.0f w-- .
