Processing method of machine tool movable support beam axis, its products and special fixture

Abstract

The present invention relates to the mobile support beam shaft of machine tool and its manufacturing method and special fixture. The processing method is characterized in that a groove parallel to the axis is provided on the side of the beam shaft for supporting guide rails, and the beam shaft with the groove is placed in a special fixture. Centering and keeping the axis on the horizontal line, the special fixture is distributed with several pairs of guide rail clips that have been corrected by the reference level on the side splint corresponding to the groove of the beam axis, insert the guide rail into the row cavity of the guide rail clip and the placement cavity of the groove , and the guide rail is fixed on the beam shaft through fasteners and the guide rail is on the horizontal line, and the beam shaft with the guide rail is obtained by removing the special clamp. The present invention has the following outstanding effects: it can ensure the straightness and parallelism of the guide rails of the mobile support beam axis after processing, and can be manufactured by template to facilitate repeated precision processing, greatly reducing the corresponding processing cost and shortening the processing period And reduce inventory, especially suitable for applications in precision, light load and long axis occasions.

Description

technical field [0001] The present invention relates to a machine tool movable support beam shaft, its manufacturing method and a special fixture, in particular to a linear movable support beam shaft applied to a high-pressure water jet cutting machine tool, its manufacturing method and a special fixture. Background technique [0002] In the machine tool, if the working head needs to move accurately on the XYZ axis, it needs to be supported by the mobile support beam axis. The mobile support beam axis is also called a linear axis or directly called the X axis, Y axis, etc., and is used to support it. Walking working head or its horizontal sliding seat. The processing and forming of the movable support beam axis needs to ensure that it is parallel, smooth and straight. This requirement directly affects the dynamic performance of the entire machine tool and the machining accuracy of the parts, and the machining accuracy is the main factor affecting the application range of the...

AI Technical Summary

Problems solved by technology

As a typical machine tool case is a high-pressure jet abrasive water jet cutting (referred to as water jet) machine tool, the cutting stroke is usually more than one meter long, and the working head needs to be positioned on the XYZ axis. If you want to obtain parallel and smooth straight The mobile support beam axis requires high processing costs, even so sometimes the accuracy cannot be guaranteed
