Support element

Abstract

Support element for supporting a workpiece clamped in a clamping device, with a wedge slide (12, 110, 220, 330) which has an inclined surface (20), the inclination of which is defined by a chamfer angle (22) and which is to be subjected to a force acting in a feed direction (40), a support bolt (14, 108, 224, 334) which has a contact area (36) which cooperates with the inclined surface (20) of the wedge slide (12, 110, 220, 330), so that a movement of the wedge slide (12, 110, 220, 330) in the feed direction (40) causes a movement of the support bolt (14, 108, 224, 334) in a support direction (42), wherein the feed direction (40) and the support direction (42) are different.

Claims

[1] Support element for supporting a workpiece clamped in a clamping device, with a wedge slide (12, 110, 220, 330) having an inclined surface (20) whose inclination is defined by a chamfer angle (22) and which is to be subjected to a force acting in a feed direction (40), a support bolt (14, 108, 224, 334) having a contact region (36) which cooperates with the inclined surface (20) of the wedge slide (12, 110, 220, 330), so that a movement of the wedge slide (12, 110, 220, 330) in the feed direction (40) causes a movement of the support bolt (14, 108, 224, 334) in a support direction (42), wherein the feed direction (40) and the support direction (42) are different. [2] Support element according to claim 1, wherein the feed direction (40) and the support direction (42) are substantially perpendicular to each other. [3] Support element according to claim 1, wherein the feed direction (40) and the support direction (42) are directed at an angle to each other which lies in a range between 80 and 100 °. [4] Support element according to one of claims 1 to 3, wherein the chamfer angle (22) is less than 45°. [5] Support element according to claim 4, wherein the chamfer angle (22) is in a range between 10 and 25 °. [6] Support element according to one of claims 1 to 5, wherein the contact area (36) of the support bolt (14, 108, 224, 334) is defined by an oblique end face (30) of the support bolt (14, 108, 224, 334), wherein the obliqueness of the end face (30) is defined by an angle (34) which corresponds to the chamfer angle (22) of the wedge slide (12, 110, 220, 330). [7] Support element according to one of claims 1 to 6, in which the wedge slide (12, 110, 220, 330) is assigned a spring (112, 222, 332) which provides the force for the movement in the feed direction (40). [8] Support element according to one of claims 1 to 7, in which the wedge slide (12, 110, 220, 330) and the support bolt (14, 108, 224, 334) are guided in a housing (102, 202, 302). [9] Support element according to one of claims 1 to 8, in which a stop bolt (218) is provided, which rests with an end face against a surface of the wedge slide (12, 110, 220, 330) and is to be subjected to a force in a direction which is directed counter to the feed direction (40) of the wedge slide (12, 110, 220, 330), wherein the stop bolt (218) is designed to inhibit a movement of the wedge slide (12, 110, 220, 330) in the feed direction (40). [10] Support element according to claim 8 and 9, wherein the stop bolt (218) is also guided in the housing (102, 202, 302). [11] Support element according to claim 9 or 10, wherein the stop bolt (218) is adjustable. [12] Support element according to claim 11, wherein the stop bolt (218) is hydraulically adjustable. [13] Support element according to claim 11, wherein the stop bolt (218) is pneumatically adjustable. [14] Support element according to claim 9 and 12 or 13, wherein the stop bolt (218) is designed as a piston (318). [15] Support element according to claim 11, wherein a contact surface of the stop bolt (218) is manually adjustable.
