Abstract

The cylinder (1) has a connection feeding hydraulic fluid to a chamber (3) under the piston (2). Belleville washers (6) fit in an annular chamber in the piston and press against a lid (5) with a conical central bore (12). The central bolt (7) fits in the central bore and has a cylindrical portion and a shoulder which may be engaged by a set of balls (10) held in a cage (8). The cage is urged toward the lid by a stack of Belleville washers (9). The balls engage in a groove inside the central portion of the piston.

Claims (11)

1. Clamping device for fastening a feed pin ( 7 ) with
a receiving opening for inserting the feed bolt ( 7 ) in the clamping device, and
a set in the clamping device in a cage ( 8 ) Rollelemen th ( 10 ), which can be pressed into an outer region of the receiving opening in order to a lateral outer surface of the feed pin ( 7 ) related to the direction of insertion of the feed pin ( 7 ) at an undercut ( 11 ) gripping the outer surface and thus jamming the pull-in bolt ( 7 ) in the receiving opening,
characterized in that the rolling elements ( 10 ) are inserted into the cage ( 8 ) through a lateral opening ( 14 ) relative to the insertion direction of a clamping device part ( 2 ) surrounding the receiving opening.
2. Clamping device according to claim 1, in which the cage ( 8 ) in the receiving opening is acted upon by a metal spring ( 9 ) against the insertion direction and the rolling elements ( 10 ) as a result of the cage ( 8 ) in an opposite of the rolling element insertion opening ( 14 ) held against the direction of insertion.
3. Clamping device according to claim 2, wherein the metal spring is a plate spring ( 9 ).
4. Clamping device according to one of the preceding claims, in which the cage ( 8 ) and the receiving opening in a cylinder ( 1 ) in and against the insertion direction mounted piston ( 2 ) are arranged, one for the in the outer region of the Receiving opening pressing the Rollele elements ( 10 ) designed contact surface for the rolling elements ( 10 ) through which the rolling elements ( 10 ) in the receiving opening inserted pin ( 7 ) in a displaced in the insertion direction of the piston ( 2 ) in the outer region of the receiving opening are pressed inwards to grip the undercut ( 11 ) of the pulling pin outer surface, and which, in a position shifted against the insertion direction of the piston ( 2 ), allows the rolling elements ( 10 ) to retreat outwards and thus the undercut ( 11 ) of the Pull pin outer surface is free, so that the pull pin ( 7 ) can be removed from the receiving opening k ann.
5. Clamping device according to claim 4, in which the piston ( 2 ) in the cylinder ( 1 ) is acted upon by springs ( 6 ) in the insertion direction and by a pressure fluid ( 3 , 4 ) against the insertion direction ( 6 ) and against the spring loading can be moved.
6. Clamping device according to one of the preceding claims, wherein the cage ( 8 ) when inserting the rolling elements ( 10 ) is rotatable about the insertion direction and a smaller number of insertion openings ( 14 ) for the rolling elements compared to the number of rolling elements ( 10 ) ( 10 ) is provided.
7. Clamping device according to one of the preceding claims, in which the cage ( 8 ) perpendicular to the insertion direction has a wall thickness which is smaller than the rolling radius of the rolling elements ( 10 ) perpendicular to the insertion direction.
8. Clamping device according to one of the preceding claims with a draw bolt ( 7 ) with a conically widening proximal Mantelab section, in which the receiving opening in a proximal Mantelab section corresponding area ( 12 ) is complementary conical.
9. clamping device with a pull-in pin ( 7 ) according to claim 8, wherein the clamping device and the pull-in pin ( 7 ) are designed such that between the conical proximal jacket portion of the pull-in pin ( 7 ) and the conical area ( 12 ) of the receiving opening in the jammed To state the feed bolt ( 7 ) results in a clearance.
10. Clamping device according to one of the preceding claims with a draw bolt ( 7 ), both of which are designed in such a way that between a front end in the insertion direction of the draw bolt ( 7 ) and a surface in the clamped position of the draw bolt ( 7 ) the clamping device in the jammed position of the feed pin ( 7 ) results in a gap.
11. Clamping device according to one of the preceding claims with at least one groove ( 15 ) for positional positioning of a workpiece cooperating with the pull-in bolt ( 7 ), which groove ( 15 ) is provided in a surface of the clamping device facing the workpiece.
