1、机械制造行业机械类外文翻译外文文献英文文献焊接机器人应用现状Weld robot application present conditionAccording to incompletely statistics, the whole world about has in the industrial robot of service nearly half of industrial robots is used for multiform weld to process realm, weld robot of application in mainly have two kinds of

2、 methods most widespreadly, then order Han and electricity Hu Han.What we says welding robot is in fact welding to produce realm to replace a welder to be engaged in the industrial robot of welding the task.These weld to have plenty of to design for being a certain to weld a way exclusively in the r

3、obot of, but majority ofly weld robot in fact is an in general use industrial robot to pack up a certain weld tool but constitute.In many task environments, a set robot even can complete include weld at inside of grasp a thing, porterage, install, weld, unload to anticipate etc. various tasks, robot

4、 can request according to the procedure with task property and automatically replace the tool on the robot wrist, the completion corresponds of task.Therefore, come up to say from a certain meaning, the development history of industrial robot is the development history that welds robot.Know to all,

5、weld to process to request that welder have to have well-trained operation technical ability, abundant fulfillment experience, stability of weld level;It is still a kind of labor condition bad, many smoke and dust, hot the radiation is big, risk Gao of work.The emergence of the industrial robot make

6、s people naturally thought of first the handicraft that replace a person with it welds and eases the welders labor strength, can also promise to weld quality and exaltation to weld an efficiency at the same time.However, weld again with other industry process process different, for example, electric

7、ity Hu Han process in, drive welder piece because of part heat melt with cool off creation transform, the Han sews of the track will therefore take place to change.Handicraft Han the experienced welder can sew position according to the actual Han observed by eyes adjustment Han in good time the posi

8、tion, carriage of the gun and run about of speed to adapt to the variety that the Han sews a track.However the robot want to adapt to this kind of variety, have to the position and status of gun that want tosee this kind of to change, then adopt homologous measure to adjust Han like person first, fo

9、llow while carrying out to sew actually to the Han.Because the electricity Hu welds to have in process strong arc light, give or get an electric shock Hu noise, smoke and dust and Rong drop transition unsteady and causable Han silk short circuit, big electric current strong magnetic field etc. compl

10、icated environment factor of existence, the robot wants to examine and identifies a withdrawing of the signal characteristic needed for sewing Han and dont seem to be industrial the other in the manufacturing to process the examination of process so easily, therefore, welding the application of robo

11、t is to used for to give or get an electric shock the process of Hu Han in the beginning.Actually, industrial robot at welded the application of realm to produce on-line electric resistance to order a Han beginning from the car assemble at the earliest stage.The reason lies in the process that the e

12、lectric resistance orders Han opposite more simple, control convenient, and not need Han to sew a track follow, to the accuracy of the robot and repeat the control of accuracy have lower request.Order the Han robot assembles to produce a great deal of on-line application to consumedly raise the rate

13、 of production that the car assemble welds and weld quality in the car, at the same time again have a gentle characteristics for welding, then want only change procedure, can produce in the same on-line carry on assemble to weld to different cars type.BE born till the beginning of this 80s in centur

14、y from the robot, the robot technique experienced a development process of long term slowness.90s, along with the rapid development of calculator technique, micro-electronics technique, and network technique.etc., the robot technique is also flown soon a development.The manufacturing level, control

15、speed and control accuracy and dependable sex etc. of industrial robot continuously raises, but manufacturing cost and price of robot continuously descend.Is social in the west, with contrary robot price BE, the persons labor force cost contains the trend to continuously increase.United Nations Euro

16、pean Economic Committee(UNECE) statisticses from the variety curve of 1990-2000 years of the robot price index number and labor force cost index number.Among them the robot price of 1990 index number and labor force cost the index number is all reference to be worth 100, go to 2000, labor force cost

17、 index number is 140, increased 40%;But robot under the sistuation that consider a quality factor the price index number is lower than 20, lowered 80%, under the sistuation that take no account of a quality factor, the price index number of robot is about 40, lowered 60%.Here, the robot price that t

18、akes no account of a quality factor means actual price of the robot of now with compared in the past;And consider that the quality factor means because the robot make the exaltation of craft technique level, manufacturing quality and function of robot even if want also under the condition of equal p

19、rice compare high before, therefore, if pressed the past robot equaled quality and function to consider, the price index number of robot should be much lower.Can see from here, national in the west, because the exaltation of labor force cost brings not small pressure for business enterprise, but the

20、 lowering of robot price index number coincidentally expands application to bring a chance further for it again.Reduce the equipments investment of employee and increment robot, when their expenses attains some one balance point, the benefit of adoption robot obviously wants to compare to adopt the

21、benefit that the artificial brings big, it on the other hand can consumedly raise the automation level of producing the equipments and raise to labor rate of production thus, at the same time again can promote the product quality of business enterprise, raise the whole competition ability of busines

22、s enterprise.Although robot 1 time invests a little bit greatly, its daily maintenance and consume is more opposite than its to producing far is smaller than completing the artificial expenses that the same task consumes.Therefore, from farsighted see, the production cost of product also consumedly

23、lowers.But the robot price lower to make some small and medium enterprises invest to purchase robot to become easy to accomplish.Therefore, the application of industrial robot is soon flown a development in every trade.According to the UNECE statistics, the whole world has 750,000 in 2001 set the in

24、dustrial robot is used for industry manufacturing realm, among them 389,000 in Japan, 198,000 in EU, 90,000 in North America, 73,000 at rest nation.Go to at the end of 2004 the whole world to have at least in the industrial robot of service about 1,000,000.Because the robot controls the exaltation o

25、f speed and accuracy and particularly give or get an electric shock the development that the Hu spreads a feeling machine to combine to weld in the robot in get an application, make the robot give or get an electric shock the Han of Hu Han to sew a track to follow and control a problem to some exten

26、t and get very solution, the robot welds in the car to make the medium application orders Han to soon develop into the car zero from originally more single car assemble partses and electricity Hu within assemble process Han.Robots giving or getting an electric shock the biggest characteristics of Hu

27、 Han is gentle, can immediately pass to weave a distance at any time a change to weld a track and weld sequence, therefore most be applicable to quilt welder piece the species variety is big, the Han sew short but many, product with complicated shape.This at the right moment again characteristics ac

28、cording to car manufacturing.Being the renewal speed of the particularly modern social car style is very quick, adopting the car production line of robot material can nicely adapt to this kind of variety.Moreover, robots giving or getting an electric shock Hu Han not only used for a car manufacturin

29、g industry, but also can used for other manufacturing industries that involve to give or get an electric shock Hu Han, like shipbuilding, motorcycle vehicle, boiler, heavy type machine etc.Therefore, the robot gives or gets an electric shock the application of Hu Han gradually extensive, on the amou

30、nt greatly have exceed the robot order the power of Han.Along with car reducing in weight manufacturing the technical expansion, some high strong metal alloy materials and light metal alloy material(is like aluminum metal alloy, and magnesium metal alloy.etc.) get an application in the material in t

31、he car structure.These materials welding usually can not solve with the welding of tradition method, have to adopt to lately weld a method and weld a craft.Among them, Gao power laser Han and agitation rub Han etc. to have to develop a potential most .Therefore, robot and Gao power laser Han and agi

32、tation rub combining of Han to become inevitable trend.Be like the public in Shanghai to wait domestic to most have the car manufacturer of real strenght in fact at their new car type manufacturing process in have already in great quantities used robot laser to weld.Give or get an electric shock Hu

33、Han to compare with robot, robot laser the Han of the Han sews to follow accuracy to have higher request.According to the general request, the robot gives or gets an electric shock the Han of Hu Han(include GTAW and GMAW) to sew to follow accuracy to control in 1| of the electrode or the Han silk diameter 2 in, at have the condition that fill the silk under t
