Embodiment Construction

[0019] figure 1 is a perspective view schematically showing the jig according to the first embodiment of the present invention. The fixture comprises a chuck generally indicated by reference numeral 1 and a workpiece holder generally indicated by reference numeral 10 provided with clamping pins 11 adapted to clamp the workpiece holder 10 in the chuck 1 . In this example, the workpiece holder simultaneously forms the workpiece itself.

[0020] The chuck 1 is connected on the workbench of the machine tool by means of a fixing device not shown, and the chuck 1 is provided with a central hole 2 for receiving and fixing a clamping pin 11 in the chuck 1 . The upper part of the central hole 2 is tapered, constituting a tapered insertion portion 3 . The top surface of the chuck is provided with a plurality of seat parts 4, once the workpiece holder 10 is finally clamped on the chuck 1, the bottom plane 10a of the workpiece holder 10 rests on the seat parts 4. Thus, the entire seat ...

Abstract

In a clamping apparatus for fixing a work piece carrier with a clamping pin in a clamping chuck, the clamping chuck is provided with a central opening for receiving the clamping pin and with a clamping mechanism firmly keeping the clamping pin in the central opening. The central opening has a conical inserting portion, and the clamping pin comprises a rear section with exposed aligning surfaces, engaging the conical inserting portion, to align the clamping pin with regard to the clamping chuck in X- and / or Y-directions. Circular seat portions on top of the clamping chuck constitute the Z-stop for the work piece carrier. For pneumatically cleaning the exposed aligning surfaces, the conical inserting portion is provided with gas outlet openings, located corresponding to the arrangement of the exposed aligning surfaces. The surface areas of the work piece carrier that will rest on the seat portions are pneumatically cleaned by gas outlet openings located in the center of the seat portions.

Description

technical field [0001] The invention relates to a fixture with a chuck and a workpiece holder with clamping pins. In particular, the fixture of the present invention includes a chuck and a workpiece holder adapted to be detachably attached to the chuck, the workpiece holder having a flat bottom surface and including clamping pins protruding from the flat bottom surface. Background technique [0002] The chuck is provided with a central hole having a tapered insertion portion for receiving the clamping pin of the workpiece holder, and a clamping mechanism for clampingly fixing the clamping pin of the workpiece holder in the central hole of the chuck. [0003] Such a fixture is preferably used for clamping a workpiece holder containing one or more workpieces to be machined in a defined and predetermined position in the machining area of ​​the machine tool. Usually, the chuck of the fixture is fixed in the processing area of ​​the machine tool, and the workpiece holder provide...
