Abstract

A mounting device for mounting a length measuring system extending in a measurement direction, the mounting device including a basic body, a steadying device attached to the basic body and a retainer attached to the basic body. A length measuring system that extends in a measurement direction is fixable on the basic body by clamping between the steadying device and the retainer, wherein the basic body and the retainer are embodied for guiding the retainer on the basic body longitudinally in a manner fixed against relative rotation in a direction of the steadying device by an adjusting element.

Claims

1. A mounting device for mounting a length measuring system extending in a measurement direction, the mounting device comprising:

a basic body, wherein a recess is formed in said basic body and wherein said recess comprises two guide faces extending parallel to one another;

a steadying device attached to said basic body;

a retainer attached to said basic body, wherein said length measuring system that extends in said measurement direction is fixable on said basic body by clamping between said steadying device and said retainer, wherein said basic body and said retainer are embodied for guiding said retainer on said basic body longitudinally in a manner fixed against relative rotation in a direction of said steadying device by an adjusting element, and wherein said retainer is guided in said recess in a manner fixed against relative rotation, and wherein said two guide faces constrain said retainer in said measurement direction; and

wherein said basic body comprises a wall with an inner attachment face, on which, with said length measuring system received on it, a face of said length measuring system rests, and said recess is made in said wall so that said retainer is guided in a manner fixed against relative rotation at a back side of said length measuring system on said basic body.

2. The mounting device according to claim 1, wherein said retainer comprises a first portion that is capable of being brought into engagement with said length measuring system, and

wherein said retainer comprises a second portion embodied for guiding said retainer on said guide face of said basic body in a manner fixed against relative rotation in said direction of said steadying device.

3. The mounting device according to claim 2, wherein said first portion of said retainer comprises a lug-like protrusion that is embodied for effecting a compression of material upon engagement with said length measuring system.

4. The mounting device according to claim 1, wherein said steadying device is a protrusion integrally formed on said basic body.

5. The mounting device according to claim 1, wherein said adjusting element is a screw, which engages a female thread of said retainer.

6. The mounting device according to claim 5, wherein said screw is drivable on both ends of said screw, in that on said both ends there is a profile for a screwdriver.

7. The mounting device according to claim 1, wherein said retainer comprises a hook with which said retainer forms a positive locking with said basic body.

8. The mounting device according to claim 1, wherein said basic body is a mounting rail extending in said measurement direction, wherein said retainer and a second retainer spaced from said retainer are positioned on said mounting rail so as to be spaced apart from one another in said measurement direction.

9. A structural unit comprising:

a length measuring system that extends in a measurement direction and comprises a scale; and

a mounting device to which said length measuring system is mounted, wherein said mounting device comprises;

a basic body, wherein a recess is formed in said basic body and wherein said recess comprises two guide faces extending parallel to one another;

a steadying device attached to said basic body;

a retainer attached to said basic body, wherein said length measuring system that extends in a said measurement direction is fixable on said basic body by clamping between said steadying device and said retainer, wherein said basic body and said retainer are embodied for guiding said retainer on said basic body longitudinally in a manner fixed against relative rotation in a direction of said steadying device by an adjusting element, and wherein said retainer is guided in said recess in a manner fixed against relative rotation, and wherein said two guide faces constrain said retainer in said measurement direction; and

wherein said basic body comprises a wall with an inner attachment face, on which, with said length measuring system received on it, a face of said length measuring system rests, and said recess is made in said wall so that said retainer is guided in a manner fixed against relative rotation at a back side of said length measuring system on said basic body.

10. The structural unit according to claim 9, wherein said length measuring system comprises said scale housing with a scale accommodated in an interior of said scale housing.
