Abstract
用于线性滚动轴承的导向轨道,其轨道主体(6)设有在导向轨道(2)纵向上看延伸的用于计量用具(4)的插口(9),其中,插口(9)在圆周面上被一体设置的轨道主体(6)的壁(10)包围。
Description
技术领域
本发明涉及一种用于线性滚动轴承的导向轨道。在这类线性滚动轴承中,例如导向托架能够利用滚轮或其它滚动体沿纵向可移动地支承在导向轨道上。
背景技术
从DE 102 43 021 A1中例如公开了一种线性滚动轴承的导向轨道,其轨道主体设有横截轨道主体纵向并敞开着的纵向槽以及用于滚动体的滚动面。纵向槽的槽底优选设有用来穿插螺栓的通孔。此外还通过盖板遮盖纵向槽,其中,在盖板遮盖的纵向槽之内设有一个纵向延伸的计量用具作为长度测量装置的一部分。盖板可以被固定在轨道主体上并可以被无损坏地去除。
这类导向轨道的制造较为昂贵,因为必须首先利用多道工序制造轨道主体,然后再把计量用具置入槽中,最后再安装盖板。
发明内容
所以,本发明的任务是,公开一种按照权利要求1前序部分特征的、能够被简单制造的、用于线性滚动轴承的导向轨道。
这一任务按照发明通过下述来解决,即插口在圆周面上被一体设置的轨道主体壁包围。依靠这种按照发明的导向轨道可以完全放弃一道工序,即单独设置的盖板的制造与安装。并且可以不用其它措施就可将轨道上侧面密封地闭合起来。如果欲将计量用具引入插口,就可以从导向轨道的一个端面将其推入插口之中。
本发明倾向以一种特殊方式设置导向轨道,其中,利用已知的方式在彼此对立的侧面上分别设置至少一个滚动面用于滚动例如滚珠或滚轮这样的滚动体,其中,插口被设置在这两个侧面之间。在这两个侧面之间可以放置轨道的上侧面。轨道主体以优选的方式含有墙,墙具有外壁与内壁。外壁被置于轨道的上侧面上,内壁是上述按照发明的壁的一个组成部分。于是插口可以位于轨道上侧面附近。被设置为薄壁的墙可以毫无问题地实现利用测量头扫描设置在插口中的计量用具,测量头优选设置在导向托架上,导向托架在导向轨道上沿纵向可移动地支承。
众所周知,导向轨道的轨道主体通常是利用冲压法从铝或铝合金中制造的。为了让插口在冲压过程中就已经得以制造,本发明使用了原始材料和方法,这样一来,墙同样也利用该冲压过程得以制造。利用这种经济上简单的方式与方法可以提供按照发明的导向轨道,其中以优选的方式一方面可以完全放弃工序,另一方面以优选的方式使用了总归的工序、也就是冲压工序。
在导向轨道的截面中可以看到,插口可以呈现任意的形状,它优选被设为直角形或椭圆形,其中,插口的角区域可以被倒圆。
将计量用具置入插口之后,通过压力工具可以使得墙可以按照下述那样被施加给压力并且发生持续形变,即计量用具在插口中可以被无间隙地固定并因此被无泄漏地固定以及定位。形变能够局部产生或在某种情况下通过插口的整体延伸而产生。
附图说明
下面将借助一个整体被示于两个图中的实施例进一步阐述本发明。
图1是按照发明的用于线性滚动轴承的导向轨道的截面;以及
图2是图1中的导向轨道的截面。
具体实施方式
图1示出的是线性滚动轴承的截面。导向托架1通过滚轮3沿纵向可移动地支承在导向轨道2上。导向托架2在其对立的侧边上分别装配了一组滚轮3,其中,导向轨道2被设置在这两组滚轮3之间。
导向轨道2在其轨道上侧面设有计量用具4。导向托架1设有在这里只被简示的测量头5。测量头5被连接在一个在这里未作描绘的处理单元上。利用这种方法可以形成长度测量装置,借助该装置可以在任何时间确定导向轨道2上的导向托架1的位置。
作为卷尺设置的计量用具可以利用金属材料来制造,当然也可以考虑塑质材料。在卷尺上可以设置测量标记。测量标记能够利用电感或电容或者借助磁阻或声馈元件或者根据涡流制造原理读出。例如在卷尺上可以设置一个带有交变的磁性南北极的磁化模型。还可以考虑的是给卷尺设置导线模型。当测量头5为了扫描测量标记而放射电场或磁场、并且该电场或磁场会被卷尺的材料影响时,传感器装置能够例如借助磁控半导体电阻或声馈传感器捕获卷尺的渗透性的波动。测量头5能够例如接受增量的信号,前提是计量用具4与测量头5之间的距离不能太大。
导向轨道2拥有冲压法制成的铝质轨道主体6。轨道主体6在其两个纵向面上分别具有槽7,轴8以环形截面嵌入其中。轴8的侧面形成用来滚动滚轮3的滚动面8a。轴8优选由被硬化过的钢制成。
计量用具4被设置在插口9中,插口9在圆周面上被轨道主体6的壁10完全包围,其中,壁10在圆周面上被一体地设置。在当前的情形中,壁10在圆周面上没有断开或开口,从而在这里形成一个圆周面闭合的插口并将计量用具4妥善地保护起来。利用冲压法制造轨道主体6可以提供壁10。轨道主体6的墙11拥有外壁11a,外壁11a设置在轨道上侧面。墙11以其内壁11b限定插口9,其中,壁11b是壁10的一部分。
冲压法可以使得墙11被设置的很薄,从而确保嵌入的计量用具4能够尽可能紧密地设置在测量头5上。
在引入计量用具4之后,压紧轮12在导向轨道2的轨道上侧面驶过,其中,压紧轮12的压紧力应按照下述调整,即墙11获得轻微的可塑变形,从而使得计量用具4能够被固定在插口9中。
在图1与图2中可以通过导向轨道2的截面看到插口9大约呈直角形并且角区域被倒圆。
按照发明的导向轨道的墙11有时候可以(只要这对于确定的应用富有意义)拥有开口,从而使得插口9在这个时候能够向着轨道上侧面敞开。
