Description
本发明是关于一种用于珠宝首饰车花加工的机床,尤其涉及一种卧式数控双刀车花机。
目前,国内外对于车花机虽有一定的研究,但仍旧存在诸多弊端。为了保证珠宝首饰车花加工的工艺性及精度,车花机的部分运动轴的相对位置必须满足严格的要求。现有车花机整机安装调试时并没有设置微调机构,各轴初始相对位置精度仅靠加工保证,势必导致装机困难且在初始位置便为保证加工精度埋下了隐患。现有车花机普遍采用立式单刀加工,效率低下,对于不同形状规格的产品,现有车花机的通用性较差且切屑回收率普遍偏低。现有的车花机装机存在调试困难、加工精度普遍不高、效率低下、对加工珠宝的形状要求严格,通用性差且切屑回收困难。

为了对本发明的技术特征、目的和效果有更加清楚的理解,现对照附图说明本发明的具体实施方式。
如图1所示,本发明提供了一种卧式数控双刀车花机,可满足高精度、高效率、高切屑回收率的加工要求。该车花机包括一个工作台,工作台上设有进刀模块和夹具模块。设定在车花机的正交坐标系中X轴和Z轴所在的平面与工作台的台面平行,Y轴垂直于工作台的台面,参见各附图中的坐标指示。夹具模块用于夹持工件,夹具模块能带动工件进行自转和摆动,工件的自转轴线与工作台的台面平行,工件的摆动轴线与工作台的台面垂直。进刀模块包括结构相同的第一进刀模块和第二进刀模块,第一进刀模块和第二进刀模块在工作台上关于工件的摆动轴线呈中心对称的设置。第一进刀模块和第二进刀模块上均设有刀具,第一进刀模块和第二进刀模块均能带动相对应的刀具沿X轴方向或Z轴方向平移,并能带动相对应的刀具围绕X轴摆动。
针对珠宝首饰车花加工工艺的特殊性,花纹往往关于工件的中心呈中心对称(如图4中A点与B点花纹一致)且进刀方向必须沿加工点的法线进给。本发明的车花机充分利用这一车花工艺的规律性,采用两个进刀模块且设置位置关于工件的摆动轴线呈中心对称,工件的摆动轴线通过工件的中心并与工作台的台面垂直,也即工件的摆动轴线与Y轴的方向一致。第一进刀模块和第二进刀模块均能带动刀具沿X轴方向或Z轴方向平移,并能带动刀具围绕X轴摆动,夹具模块能带动工件进行自转和摆动,X轴方向为刀具的进刀方向,通过工件的摆动使加工点的法线方向与X轴方向重合。通过合理分配进刀模块与夹具模块各轴的运动,该车花机具有八轴的加工自由度,利用各模块各轴的组合运动使其加工过程中可以实现双刀同时加工,以及各种不同花纹的加工,大大提高加工的效率。
进一步,安装刀具的刀架通过燕尾槽调整机构与X轴摆动装置连接,燕尾槽调整机构能使刀具沿着Z轴方向和Y轴方向进行调整,实现装配后刀具的校准和调试,保证加工产品的精度。
进一步,夹具模块设有固定夹具安装座和移动夹具安装座,固定夹具安装座和移动夹具安装座上分别通过中间连接件能拆卸的安装有第一顶尖和第二顶尖。移动夹具安装座能相对固定夹具安装座进行滑移,从而通过第一顶尖和第二顶尖将工件夹紧或松开。当加工不同规格尺寸的工件时,只需通过中间连接件拆卸、更换不同长度规格的第一顶尖和第二顶尖即可,加上夹具模块与进刀模块各轴的相互配合运动可实现不同形状、不同规格的产品加工,提高车花机的通用性。
进一步,第一进刀模块与夹具模块之间、第二进刀模块与夹具模块之间均设有切屑收集盒,工作台上还设有切屑排出口,工作台的下方设有切屑收集装置,工作台上的切屑通过切屑排出口落入切屑收集装置中。解决了进刀模块与夹具模块之间距离短,不便于清扫切屑问题的同时,能收集绝大部分切屑。
作为本发明的一个具体实施例,如图1至图3所示,本发明提供一种卧式数控双刀车花机100,主要由第一进刀模块33、第二进刀模块36、夹具模块34三大核心部分构成。机架1上设有一个工作台2,第一进刀模块33、第二进刀模块36和夹具模块34都设置在工作台2上,其中,第一进刀模块33和第二进刀模块36结构相同,两者的安装位置关于工件的摆动轴线呈中心对称。其中,各进刀模块包括Z轴平移台4、X轴平移台6、X轴摆动装置7及刀架12。Z轴平移台4固定在工作台2上,Z轴平移台4沿着Z轴方向延伸设置。X轴平移台6设置在Z轴平移台4上,在Z轴平移驱动元件3驱动下

X轴摆动装置7设置在X轴平移台6上,在X轴平移驱动元件5驱动下沿X轴平移;且X轴摆动装置7在X轴摆动驱动元件71的驱动下绕X轴摆动。具体的,X轴平移台6上设有X轴平移件(图中未示出),X轴平移件在X轴平移驱动元件5驱动下沿X轴平移,X轴平移驱动元件5设在X轴平移台6的一端,通过直线模块驱动X轴平移件沿X轴平移。X轴平移件上固定有一沿Y轴方向延伸的导向轴17,X轴摆动装置7中的支座72滑动设置在导向轴17上,并通过锁紧螺钉16与导向轴17相对固定。通过调节锁紧螺钉16,可实现X轴摆动装置7沿导向轴17上下移动,实现X轴摆动装置7的摆动轴线沿Y轴方向的微调。支座72上固定有X轴摆动驱动元件71,X轴摆动驱动元件71的转动输出轴沿X轴方向设置,转动输出轴上固定连接一法兰连接件73,能带动该法兰连接件73转动。刀架12通过燕尾槽调整机构9连接在法兰连接件73上与其一起绕X轴摆动,刀具121设置在刀架12上。其中,燕尾槽调整机构9包括第一调整件91、第二调整件92、第三调整件93。第一调整件91的一侧与法兰连接件73固定连接,另一侧设有沿Z轴方向延伸的第一燕尾槽。第二调整件92的一侧设有与第一燕尾槽配合的滑动块,通过滑动块与第一调整件91的第一燕尾槽滑动连接,另一侧设有沿Y轴方向延伸的第二燕尾槽。第三调整件93的一侧设有与第二燕尾槽配合的滑动块,通过该滑动块与第二调整件92的第二燕尾槽滑动连接,另一侧与刀架12固定连接。第一调整件91、第二调整件92、第三调整件93之间还具有能使其两者之间相对固定的固定装置,防止在外力作用下产生偏移。通过调整第二调整件92在第一燕尾槽中的位置来调整刀具在Z轴方向的位置,通过调整第三调整件93在第二燕尾槽中的位置来调整刀具在Y轴方向的位置,实现X轴方向通过刀具121中心的中心线与X轴摆动装置7的摆动轴线重合。Z轴平移台4和X轴平移台6上均设有防止切屑落入其中的柔性风琴罩18(现有技术)。
刀具121转动设置在刀架12上,刀架12上固定设有刀具驱动元件10及带轮组11,刀具驱动元件10通过传动带绕过带轮组11连接至刀具121,带动刀具121高速旋转(刀具的自转)进行加工。刀架12上还设有防护罩,防护罩由钣金件组成,将带轮组11封装起来,防止切屑进入其中。各进刀模块均可实现刀具121沿X、Z轴的平动及绕X轴
的摆动,同时,还能实现刀具121在Z轴、Y轴方向的调整及X轴摆动装置7的摆动轴线沿Y轴方向的微调,达到刀具沿X轴方向的中心线、绕X轴的摆动轴线、通过工件中心的水平面三者重合。可轻松完成装机调试工作,最大限度的保证了加工所要求的精度。
如图3所示,夹具模块34包括夹具安装底板24、固定夹具安装座26、移动夹具安装座13、工件自转驱动元件25、夹具移动驱动元件30、工件摆动驱动元件23。夹具安装底板24的下侧与夹具摆动轴32固定连接,夹具摆动轴32垂直于工作台2的台面,即与Y轴方向一致。夹具安装底板24的上侧固定设有一水平滑轨29。固定夹具安装座26固定设置在夹具安装底板24上,位于水平滑轨29的一端。固定夹具安装座26上转动设有第一顶尖281,第一顶尖281的转动轴线平行于工作台2的台面。移动夹具安装座13滑动设置在水平滑轨29上。移动夹具安装座13上转动设有第二顶尖282,第二顶尖282与第一顶尖281相对设置且两者的转动轴线重合,将工件夹持在两个顶尖之间,工件自转驱动元件25驱动第一顶尖281转动,并由第一顶尖281带动工件进行自转。夹具移动驱动元件30驱动移动夹具安装座13沿水平滑轨29滑动,向接近或远离固定夹具安装座26的方向移动,进而夹持或放开工件。工件摆动驱动元件23驱动夹具摆动轴32转动。第一顶尖281通过中间连接件27能拆卸的安装在固定夹具安装座26上;第二顶尖282通过中间连接件27能拆卸的安装在移动夹具安装座13上。夹具安装底板24上设有缓冲元件31,缓冲元件31位于移动夹具安装座沿水平滑轨29远离固定夹具安装座26的方向上,并能触碰到移动夹具安装座13,当松开工件时,缓冲元件31起到缓冲作用。夹具摆动轴32通过轴承座20转动设置在工作台2上,工件摆动驱动元件23通过驱动元件安装座22安装在工作台2下方。夹具模块34可实现工件的自转及绕Y轴的摆动。
在本实施例中,上面提到的各个驱动元件,可以采用现有技术中的多种驱动方式,例如电机、气动或液压马达等。上面提到的直线模块,可以采用现有技术中的多种方式,例如丝杠滑块、直线轴承等。
第一进刀模块33与夹具模块34之间、第二进刀模块36与夹具模块34之间均设有切屑收集盒19,切屑收集盒19设置在工作台2上,切屑收集盒19通过磁铁吸附在轴承座20上。解决进刀模块与夹具模块之间距离短不便于清扫切屑的问题。工作台2上还设有切屑排出口35,如图2所示,可以在夹具模块34的两端分别设置一个切屑排出口35,在每个切屑排出口35对应的工作台2的下方设有切屑收集装置21,工作台2上的切屑通过切屑排出口35落入切屑收集装置21中,溅落在工作台2上切屑通过切屑排出
口35扫入工作台2下方的切屑收集装置21中,能收集绝大部分切屑。
本发明的装机调试过程为:装配时通过调整进刀模块33、36中的燕尾槽调整机构9实现刀具121沿X轴方向的中心线与X轴摆动装置7的摆动轴线重合。通过调节锁紧螺钉16,使X轴摆动装置7沿导向轴17上下移动,实现重合后的刀具121沿X轴方向的中心线及摆动轴线在Y轴方向微调,从而与通过工件中心的水平面(即平行于X轴、Z轴所在平面且通过工件中心的平面)重合。进而通过Z轴平移驱动元件3控制刀具121沿Z轴移动,实现刀具121沿X轴方向的中心线及X轴摆动装置7的摆动轴线(两者已经调整为重合)穿过工件的中心,至此装机调试完成。
下面以椭球形加工件为例具体说明加工过程,夹具移动驱动元件30驱动移动夹具安装座13沿水平滑轨29移动,实现工件的加紧,此时工件的自转轴线与Z轴一致,刀具的进给方向为X方向。参见图4,n代表加工点处曲面的法线方向,f代表加工点处刀具的进给方向,在A点和B点处两者的夹角为19度,该夹角根据工件的曲面不同而不同。需要加工的A点与B点关于工件的中心对称,花纹一致且进刀方向f必须沿加工点的法线方向n。由于两个进刀模块的位置关于工件的摆动轴线(工件的摆动轴线通过工件的中心)呈中心对称,通过控制夹具模块34的工件摆动驱动元件23驱动工件绕Y轴(与其摆动轴方向一致)顺时针旋转19度,如图5所示,这时A点与B点的法线方向n均与刀具的进给方向f一致。通过同时控制各进刀模块的Z轴平移驱动元件3进行刀具121沿Z轴的移动,使两刀具121分别移动至A点及B点。通过同时控制各进刀模块的X轴平移驱动元件5实现刀具121沿X轴的进给,即沿A点与B点刀具进给方向f的进给,同时也是沿A点与B点法线方向n的进给,X轴摆动装置7可实现刀具121绕X轴任意角度的摆动,即可在A、B点加工更为复杂的花纹(如米字花纹),实现同时完成A点与B点的加工。当加工不同尺寸的工件时,只需通过中间连接件27拆卸、更换不同长度规格的顶针281、282即可。对于形状为球形或圆柱形的工件,加工方法则更为简单。对于球形工件,进刀模块无需使刀具沿Z轴的平动便可实现双刀加工。对于圆柱形工件,夹具模块无需绕Y轴旋转便可双刀加工。因此,本发明的车花机相对于传统车花机通用性大大提高。本发明适用球形、椭球形、圆柱体等各种珠宝首饰的车花加工,适用性极强。
由上所述,本发明的车花机根据珠宝首饰车花加工的特殊性,花纹往往关于工件的中心呈中心对称且进刀方向须沿加工点的法线进给,采用两个进刀模块且设置位置关于工件的摆动轴线呈中心对称,通过合理分配各进刀模块与夹具模块各轴的运动,利用各
模块中各轴的组合运动实现双刀同时加工,大大提高加工的效率,也可实现不同形状,不同规格的产品加工,提高车花机的通用性。通过调节进刀模块中的燕尾槽调整机构,易于装机调试并保证加工产品的精度。通过合理布置简单实用的切屑回收装置,大大提高切屑的回收效率。
以上所述仅是本发明的较佳实施例而已,并非对本发明做任何形式上的限制,虽然本发明已以较佳实施例揭露如上,然而并非用以限定本发明,任何熟悉本领域的普通技术人员,在不脱离本发明技术方案的范围内,当可利用上述揭示的技术内容作出些许更动或修饰为等同变化的等效实施例,但凡是未脱离本发明技术方案的内容,依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与修饰,均仍属于本发明技术方案的范围内。
