文档介绍:摘要
机械手是自动换刀装置中交换刀具的主要工具,它担负着把刀库上的刀具送到主轴上,再把主轴上已用过的刀具返回刀库上的任务。
设计思路是用机械手的动作来实现对加工中心的换刀,机械手的转动有回转液压缸运来实现,其动力则由驱动系统实现。
加工中心的自动换刀装置,通常是由刀库和机械手组成,它是加工中心的象征,又是加工中心成败的关键环节。因此各加工中心制造厂家都在下大力研制动作迅速、可靠性高的自动换刀装置,以求在激烈的竞争中取得好效益,自动换刀装置是加工中心的核心内容,各厂家都在保密,极少公开有关资料,尤其机械手部分更是如此。
这种机械手的拔刀、插刀动作,大都由油缸动作来完成。根据结构要求,可以采用油缸动,活塞固定;或活塞动,油缸固定的结构形式。
整个机械手由机械臂伸缩机构,机械爪开合机构,回转机构及装卸刀具直线运动机构组成。
Summary
The machine hand changes the knife automatically to exchanges the main tool that knife have in the device, it carry to have the knife the knife on the sends to the principal axis last, useses again the principal axis the top already over of the knife has to return the knife the mission on the .
Designing the way of thinking is to uses the action of the machine hand realizes centrally to process to change the knife, the machine turns to move the turn-over liquid presses the urn carries realize, its motive is then from drive the system realizes.
Process the central changing the knife the device automatically, usually constitute with the machine from the knife , it is a key to process the central symbol, again is process the center ess or failure each process the center manufactory house to all obtain the performance in descend strongly research to manufacture action quickly, dependable highly automatically change the knife device, in order to in the petition, change the knife automatically the device is to process the central core contents, each factory house is all at keep secret, minimum amount public relevant data, particularly the cent of machine hand is also such.
This kind of machine pulls out the knife and put the knife acts, mostly from oil an action according to the construction, can adopt the oil urn move, the piston fixs;Or the piston moves, oil a fixed construction form.
Whole machine hand from anization in machine arm, the machine claw opens to match anization, turning round anization and packing to unload the knife have the straight line the spor
