Three-axis machining center multi-station fixture

Abstract

The invention discloses a multi-station fixture for a three-axis processing center. The multi-station fixture for the three-axis processing center comprises a fixture body (1) rotationally mounted on a working table bracket of the processing center, and the fixture body (1) comprises a positioning device for fixing a workpiece and a cavity through which a processing tool inserted into the workpiece for processing. The fixture body (1) rotationally mounted on the working table bracket of the processing center means that the fixture body (1) further comprises two end plates (2), one end of the fixture body (1) is connected with a rotary axis (7) fixed at the processing center through the end plate (2), the other end of the fixture body (1) is connected with a movable bearing (8) fixed at the processing center through the end plate (2), and the axis of the rotary axis (7) is in a same straight line with that of the movable bearing (8). The multi-station fixture for the three-axis processing center is applicable to processing various irregular workpieces by the three-axis processing center.

Problems solved by technology

[0002] For some irregular workpieces, such as symmetrical parts on medical equipment beds, the flatness of the product will be warped due to force and heat after bending and welding, which will bring difficulties to the clamping of the machining center and be easy to Uneven stress occurs, and irregular workpieces often require multi-face machining. The existing three-axis machining centers only have three coordinates, that is, XYZ. Generally, they can only process the surface facing the tool. How many surfaces need to be processed need to be dismantled How many times to install, this is a processing problem that has existed in the industry for many years, and the installation surface of the product is required to be flat when clamping, so as to ensure uniform stress distribution during processing

This kind of fixture not only needs to be disassembled and assembled according to the surface to be processed during processing, which makes the processing efficiency low, but also has high requirements on the flatness of the workpiece, which is not suitable for clamping various irregular workpieces and increases the production cost.
