Description

固定整体量具支架的机构 和支架固定方法及长度测量装置
技术领域
本发明涉及一种如权利要求1前序部分所述的用于固定整体量具的支架的机构以及一种如权利要求9前序部分所述的用于固定该支架的方法以及一种如权利要求12所述的长度测量装置。
背景技术
长度测量装置由一个整体量具支架和一个扫描该整体量具的扫描单元组成。它们尤其在用于对刀具相对于要被加工工件的相对运动进行测量的加工设备上、在机器人上、在坐标测量机上应用并且也大量地用于半导体工业。
在DE 83 02 162 U1中描述了一种用于固定整体量具支架的机构。该机构具有一个卡紧钳，它使一个长度测量装置的外壳顶压在一个要被测量物体的一个装配面上。该卡紧钳通过一个螺栓固定在要被测量的物体上，其中该卡紧钳与外壳的一个倾斜的夹紧面共同作用。由此使该卡紧钳通过螺栓以一个力分量顶压在装配面上，并且以一个第二力分量顶压一个横向于装配面延伸的止挡面。这个止挡面是卡紧钳本身的一个突起。
在旋紧螺栓时卡紧钳对外壳施加一个夹紧力。同时该卡紧钳移动并由此也使成形在其上的止挡面移动。由此使这个止挡面对于外壳没有确定的和稳定的定位和取向辅助机构。
发明内容
本发明的目的是给出一种用于固定整体量具支架的机构，通过它使该支架以简单的方式固定在一个装配面上，并且能够实现该支架明确的定位和取向。
这个目的按照本发明通过权利要求1的特征达到。
DE 83 02 162 U1也描述了一种用于使整体量具支架固定在一个装配面上的方法。在此一个卡紧钳通过将一个螺栓旋进要被测量的物体而顶压在一个长度测量装置的外壳的一个夹紧面上。由此在外壳上施加一个夹紧力，它使外壳顶压在装配面上并且顶压在卡紧钳的一个止挡面上。在卡紧钳固定在要被测量的物体上以后，使卡紧钳通过销固定而形状配合连接地固定在要被测量的物体上。
因为形状配合连接的固定只有在产生夹紧力以后才能实现，不可能防止止挡面在固定期间的位移。
通过本发明也要提供一种方法，通过该方法以简单的方式可以使一个整体量具的一个支架固定在一个装配面上，并且通过该方法能够实现支架明确的定位和取向。
这个目的通过权利要求9的特征达到。
此外给出一种长度测量装置，它可以方便地固定并且可以明确地定位。
通过本发明实现的优点是，所述止挡面在横向于装配面的一个方向上的位置尽可能保持不受卡紧钳本身位移的影响。因为该止挡面直接由形状配合连接地锚接在要被测量物体中的止挡体本身构成，并且这个止挡体稳定地固定在要被测量的物体的一个配合容纳孔里面，该支架的定位和取向明确地通过由止挡体构成的止挡面的位置给定。也可以实现一种简单的操作，因为所述止挡体构成卡紧钳的固定体，并且该卡紧钳在装配时可以在止挡体的纵向上移动。
在从属权利要求中给出本发明的有利的结构方案。

具体实施方式
在图1至5中示出本发明的第一实施例。图1示出一个被封盖的具有一个空心型材形式外壳1的长度测量装置，在外壳内部固定一个刻度尺2。该刻度尺2具有测量刻度3，它由一个相对于刻度尺2在测量方向X上可移动的扫描单元扫描。该扫描单元通过一个同步体4与要被测量的物体5连接。这个物体5例如是机床的床身。
所述外壳1作为具有测量刻度3的刻度尺2的支架，它通过至少一个卡紧钳6固定在另一要被测量的物体7的一个装配面M上。这个物体7例如是一个机床的滑座。
所述卡紧钳6这样构成，使作用于外壳1上的卡紧钳6的夹紧力K分解成在一个垂直于外壳1长度的平面中、即在剖切面II-II中的两个相互垂直的力分量K1和K2。为此使与卡紧钳6对应的外壳1夹紧面S相对于装配面M倾斜。该卡紧钳6使外壳1通过一个力分量K2顶压在装配面M上，并通过另一力分量K1直接顶压一个止挡体8的定位面A。
所述止挡体在这个实施例中是一个配合销8，它形状配合连接且无间隙地固定在要被测量的第一物体7上的一个配合孔9形状的容纳孔里面。该配合销8与配合孔9构成压配合。
最好这样选择该配合销8的长度，使得外壳1在其整个宽度上贴靠在配合销8上。
所述卡紧钳6具有一个通孔D，通过它使卡紧钳在配合销8的纵向上在这个配合销上导引。为了施加夹紧力K，一个螺栓10形式的施力元件旋进配合销8里面。通过这个螺栓10使卡紧钳6在配合销8的纵向上在这个配合销上移动。
图3至5示出用于使外壳1固定在要被测量物体7的装配面M上的单个方法步骤。在第一方法步骤中使配合孔9在物体7里面掏制而成并且压入配合销8。在图3中简示出为此使用的压入工具11。
该配合销8构成用于止挡外壳1的止挡面A。在外壳1止挡在配合销8上以后使卡紧钳6与外壳1的夹紧面S接触，如同在图4中所示的那样。在此该卡紧钳6通过其通孔D插到配合销8上。
现在按照图5将螺栓10旋进配合销8的一个内螺纹里面并由此产生夹紧力K。在此所述卡紧钳6相对于配合销8在纵向上移动并且在其上导引，但是在此没有用于外壳1止挡面A的位置移动。在此保持所述外壳1通过配合销8给定的取向。
本发明也特别有利地用于相对较长的外壳1，对于该外壳为了稳定地固定必须使用多个卡紧钳6。在这里首先将所有的配合销8在一条直线中插入到物体7里面，然后使外壳1止挡在配合销上并由此定向。接着使卡紧钳6与外壳1接触并分别施加用于使外壳1不可移动的固定所需的夹紧力K。对于按照图1的实施例使用例如两个在测量方向X上相互间隔的卡紧钳6来使外壳1取向和稳定地固定。
下面借助于图6至11的结构来描述在很大程度上对应于第一实施例的长度测量装置。用于固定的机构和方法也对应于上述的实施例，因此下面只描述与第一实施例的不同之处。
在按照图6的实施例中通过一个螺母10.1替换螺栓10，该螺母旋到配合销8.1的外螺纹上并且使卡紧钳6在配合销8.1的纵向上移动。
在图7中所示的实施例对应于按照图6.1的实施例，只是现在将夹紧面S设置在外壳1的一个槽里面并且使卡紧钳6.2在该槽中与外壳1共同作用。
在按照图8的第四实施例中所述止挡体是一个配合销8.2，它具有一个用于形成配合的配合部位，用来在物体7的配合孔9.2里面定中心；并且具有一个螺纹段12用来使配合销8.2旋进物体7里面。
如图9所示，一个配合套8.3也承担止挡面A的功能，该配合套无间隙地容纳在一个配合孔9.3里面。所述卡紧钳6.3现在通过一个旋进或旋紧在配合套8.3里面的螺栓或螺母固定，或者如图9所示，通过一个螺栓10.3旋进物体7里面。
在按照图10的第六实施例中配合销8.4满足与第一实施例相同的功能，不同之处是，所述卡紧钳6.4通过一个在配合销8.4旁边旋进的螺栓10.4顶压夹紧面S。
借助于图11描述的第七实施例在很大程度上对应于图9的实施例，只是配合套8.3替换成一个销8.5。所述销8.5是一个螺栓销，其中在孔9.5中夹紧形式的稳定的锚接同时通过螺栓10.5通过施加卡紧钳6.5夹紧力来实现。在此所述销8.5的一部分压紧或楔紧在孔9.5里面。在未示出的方式中代替螺栓销也可以使用一个打入销。
代替外壳1作为测量刻度或整体量具3的支架，也可以使具有上述装置的刻度尺2本身固定在装配面M上。然后使夹紧面直接设置在刻度尺上，并且使卡紧钳直接与刻度尺共同作用并且使这个刻度尺顶压装配面以及止挡体。
借助于在图12中所示的第八实施例描述一种有利的外壳1的结构方案。与止挡体8对置的外壳1表面具有两个相互间隔的突起20，21，它们使止挡体8有限地接触。因此所述外壳1在这两个突起20，21的间距方向上的凸起或凹下的拱曲不影响在止挡体8上的靠置。所述突起20，21最好是在测量方向X上延伸的短臂，它们也可以局部中断地构成。所述外壳1的这种结构方案可以应用于所有上述的示例。
