Abstract

The invention discloses a clamping method for a pipe workpiece fixture. The clamp includes a connecting shaft, a hydraulic oil device, a hydraulic diameter expanding mechanism, a displacement detecting device, a pressure detecting device and a host computer, wherein one end of the connecting shaft is connected to the The machine tool spindle is connected, and the other end of the connecting shaft is evenly provided with multiple hydraulic diameter expanding mechanisms along the circumference of the connecting shaft on the same plane. The multiple hydraulic expanding mechanisms are supported on the inner wall of the workpiece to support and clamp the workpiece. The invention clamps the workpiece through several hydraulic diameter expanding mechanisms, and detects the workpiece through double detection mechanisms to ensure accurate clamping of the workpiece.

Description

technical field [0001] The invention relates to a clamping method for a pipe workpiece fixture. Background technique [0002] Machine tool fixtures can be divided into the following categories according to specialized classification: [0003] 1. General fixture. Universal fixtures refer to fixtures that have been standardized and can be used to process different workpieces within a certain range. For example, three-jaw chucks and four-jaw single-action chucks on lathes, vises, dividing heads, and rotary tables on milling machines. Such fixtures are generally produced by professional factories and are often provided to users as machine tool accessories. It is characterized by wide adaptability and low production efficiency, and is mainly suitable for single-piece and small-batch production. [0004] 2. Special fixture. Special fixtures refer to fixtures specially designed for a certain process of a certain workpiece. It is characterized by compact structure, fast, conve...
