Abstract

The invention discloses a clamp locking method on a precision machine tool. The clamp includes an electromagnetic chuck, a hydraulic oil device, a hydraulic propulsion mechanism, a displacement detection device, a pressure detection device and a lower computer, wherein the electromagnetic chuck is evenly arranged along the disk circumference Several hydraulic propulsion mechanisms, several hydraulic propulsion mechanisms can lock or loosen the workpiece; each hydraulic propulsion mechanism is connected to the hydraulic oil device through an electromagnetic reversing valve; the displacement detection device is used to detect the position of the workpiece in real time; the The pressure detection device is arranged in the hydraulic circuit of each hydraulic propulsion mechanism; the lower machine is connected with the electromagnetic chuck, hydraulic oil device, electromagnetic reversing valve, displacement detection device and pressure detection device. The clamp locking method on the precision machine tool of the present invention locks the workpiece through several hydraulic propulsion mechanisms, and detects the workpiece through double detection mechanisms to ensure accurate locking of the workpiece.

Description

technical field [0001] The invention relates to a method for locking a fixture on a precision machine tool and a method for locking the same. Background technique [0002] Machine tool fixtures can be divided into the following categories according to specialized classification: [0003] 1. Universal 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, vise, indexing 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. A special fixture refers to a fixture specially designed for a certain process of a workpiece. It is charac...
