Abstract

A precision coupling for securing a component to an apparatus. The precision coupling includes a first coupling half for connection to the apparatus and a second coupling half for connection to the component. The first coupling half has a clamping lever configured for pivoting about a pivot axle, the clamping lever having at least one lateral flap with a first inclined tightening face. The second coupling half has at least one locking finger with a second inclined tightening face so that when the clamping lever is pivoted and the first coupling half and the second coupling half are placed against each other in an open position, the at least one lateral flap engages behind the at least one locking finger and the first inclined tightening face slides along the second inclined tightening face and to thereby pull the first coupling half and the second coupling half against each other in order to assume a locking position.

First claim

What is claimed is:

1 . A precision coupling for securing a component to an apparatus, the precision coupling comprising:
a first coupling half having a clamping lever configured for pivoting about a pivot axle, the clamping lever having at least one lateral flap with a first inclined tightening face; and a second coupling half having at least one locking finger with a second inclined tightening face so that when the clamping lever is pivoted and the first coupling half and the second coupling half are placed against each other in an open position, the at least one lateral flap engages behind the at least one locking finger and the first inclined tightening face slides along the second inclined tightening face and to thereby pull the first coupling half and the second coupling half against each other in order to assume a locking position.

2 . The precision coupling of claim 1 , wherein:
the clamping lever comprises a lateral contour and a resiliently loaded fixing pin configured to slide along the lateral contour when the clamping lever is activated, and the lateral contour has a curve which radially declines in the direction towards the locking position.

3 . The precision coupling of claim 2 , wherein the lateral contour comprises a notch and the resiliently loaded fixing pin engages in the notch in the open position.

4 . The precision coupling of claim 1 , further comprising a central positioning stud on the pivot axle of the first coupling half to facilitate pivoting of the clamping lever thereabout can be pivoted about the central positioning stud.

5 . The precision coupling of claim 4 , wherein the second coupling half comprises a central opening to facilitate positioning of the first coupling half and the second coupling half with respect to each other by introducing the central positioning stud into the central opening.

6 . The precision coupling of claim 1 , further comprising at least one non-central positioning stud and an opposing non-central opening to facilitate securing of the first coupling half and second coupling half against rotation relative to each other.

7 . The precision coupling of claim 1 , wherein:
the first coupling half comprises a receiving space for the clamping lever, and limitations of the receiving space limit a possible path for pivot movement of the clamping lever, the receiving space is axially terminated by a closure plate.

8 . The precision coupling of claim 1 , wherein an inclination of the first inclined tightening face and an inclination of the second inclined tightening face are approximately 3 degrees.

9 . The precision coupling of claim 1 , wherein:
the first coupling half comprises one or more first fastening members for securing the first coupling half to the apparatus, and the second coupling half comprises one or more second fastening members for securing the second coupling half to the component.

10 . A precision coupling for securing a component to an apparatus, the precision coupling comprising:
a first coupling half having a clamping lever configured for pivoting about a pivot axle, the clamping lever having at least two lateral flaps arranged are opposite each other with the pivot axle as a centre point, each lateral flap in the at least two lateral flaps having a first inclined tightening face; and a second coupling half having at least two locking fingers, each locking finger in the at least two locking fingers having a second inclined tightening face so that when the clamping lever is pivoted and the first coupling half and the second coupling half are placed against each other in an open position, the at least two lateral flaps engage behind the at least two locking fingers and the first inclined tightening face slides along the second inclined tightening face and to thereby pull the first coupling half and the second coupling half against each other in order to assume a locking position.

11 . The precision coupling of claim 10 , wherein:
the clamping lever comprises a lateral contour and a resiliently loaded fixing pin configured to slide along the lateral contour when the clamping lever is activated, and the lateral contour has a curve which radially declines in the direction towards the locking position.

12 . The precision coupling of claim 11 , wherein the lateral contour comprises a notch and the resiliently loaded fixing pin engages in the notch in the open position.

13 . The precision coupling of claim 10 , further comprising a central positioning stud on the pivot axle of the first coupling half to facilitate pivoting of the clamping lever thereabout can be pivoted about the central positioning stud.

14 . The precision coupling of claim 13 , wherein the second coupling half comprises a central opening to facilitate positioning of the first coupling half and the second coupling half with respect to each other by introducing the central positioning stud into the central opening.

15 . The precision coupling of claim 10 , further comprising at least one non-central positioning stud and an opposing non-central opening to facilitate securing of the first coupling half and second coupling half against rotation relative to each other.

16 . The precision coupling of claim 10 , wherein:
the first coupling half comprises a receiving space for the clamping lever, and limitations of the receiving space limit a possible path for pivot movement of the clamping lever, the receiving space is axially terminated by a closure plate.

17 . The precision coupling of claim 10 , wherein an inclination of the first inclined tightening face and an inclination of the second inclined tightening face are approximately 3 degrees.

18 . The precision coupling of claim 10 , wherein:
the first coupling half comprises one or more first fastening members for securing the first coupling half to the apparatus, and the second coupling half comprises one or more second fastening members for securing the second coupling half to the component.

19 . A precision coupling for securing a component to an apparatus, the precision coupling comprising:
a first coupling half having a clamping lever configured for pivoting about a pivot axle, the clamping lever having at least one lateral flap; and a second coupling half having at least one locking finger so that when the clamping lever is pivoted and the first coupling half and the second coupling half are placed against each other in an open position, the at least one lateral flap engages behind the at least one locking finger and slides along the at least one locking finger to thereby pull the first coupling half and the second coupling half against each other in order to assume a locking position.

20 . The precision coupling of claim 19 , wherein:
the first coupling half comprises one or more first fastening members for securing the first coupling half to the apparatus, and the second coupling half comprises one or more second fastening members for securing the second coupling half to the component.
