Fastening system with eccentric
View Patent ↗Fastening system for a linear machine element ( 2, 102 ) for fastening in a machine foundation ( 4 ), having a clamping element which has a shank ( 35 ) and a head ( 37 ), wherein the diameter of the head ( 37 ) is greater than the diameter of the shank ( 35 ), and having an eccentric ( 60 ) which comprises a sleeve ( 68 ) with an eccentric bore ( 66 ) and a torque-transmitting element ( 70 ), wherein the outer diameter of the head ( 37 ) is smaller than the inner diameter of the bore ( 66 ) or at least substantially corresponds to the inner diameter of the bore ( 66 ).
1. Fastening system for a linear machine element having a toothed rack or a linear guide for fastening in a machine bed, comprising:
a clamping element having a shank and a head, wherein the head has a diameter which is greater than the shank diameter;
an eccentric comprising a sleeve having an eccentric bore and a torque-transmitting element, wherein the diameter of the head is smaller than the eccentric bore diameter;
a linear machine element having a through-opening in which the clamping element and the sleeve of the eccentric are received; and
wherein the shank of the clamping element comprises a thread engaging with a threaded opening of the machine bed.
2. Fastening system according to claim 1 , wherein the torque-transmitting element is arranged concentrically with respect to the eccentric bore.
3. Fastening system according to claim 1 , wherein the eccentric bore extends through the torque-transmitting element.
4. Fastening system according to claim 1 , wherein the eccentric bore comprises a step.
5. Fastening system according to claim 1 , wherein the through-opening comprises a shoulder.
6. Fastening system according to claim 5 , wherein the through-opening is formed on a first side of the shoulder as a slot.
7. Fastening system according to claim 6 , wherein the through-opening is formed on a second side of the shoulder as a circular hole.
8. Fastening system according to claim 1 , wherein the eccentric comprises the following:
a sleeve with an eccentric bore;
a torque-transmitting element which is arranged on one axial end of the sleeve; and
wherein the bore extends through the sleeve and through the torque-transmitting element.
9. Fastening system according to claim 1 , wherein the through-opening for receiving a clamping element and a sleeve of an eccentric comprises a shoulder, and wherein the opening is formed, on a first side of the shoulder, as a slot and, on a second side of the shoulder, as a circular hole.
10. Method for the fastening of a linear machine element comprising a toothed rack or a linear guide with at least one through-opening in a machine bed using the fastening system according to claim 1 , the method comprising the steps of:
orienting the machine element in the machine bed;
inserting the clamping element into the at least one through-opening of the machine element;
inserting the at least one eccentric into the at least one through-opening of the machine element and mounting the eccentric on the head of the clamping element;
orienting the eccentric in the through-opening in order to position the machine element; and
tightening the clamping element in order to fix the machine element in the machine bed.
11. Fastening system for a linear machine element having a toothed rack or a linear guide for fastening in a machine bed, comprising:
a clamping element having a shank and a head, wherein the head has a diameter which is greater than the shank diameter;
an eccentric comprising a sleeve having an eccentric bore and a torque-transmitting element, wherein the torque-transmitting element is arranged concentrically with respect to the eccentric bore, wherein the diameter of the head is smaller than the eccentric bore diameter; and
a linear machine element having a through-opening in which the clamping element and the sleeve of the eccentric are received.
