A method for flexible assembly of machine tools

Abstract

The invention discloses a machine tool flexible assembly method. Flexible assembly is implemented on a regular numerical control machine tool through a machine tool flexible assembly device. The machine tool flexible assembly device comprises a CCD, a distance measurement assembly and an accompanying assembly mechanism, wherein the CCD is connected with the numerical control machine tool; the distance measurement assembly is mounted in front of a to-be-milled and riveted workpiece; the to-be-milled and riveted workpiece is arranged in the accompanying assembly mechanism; in the accompanying assembly mechanism, a supporting body used for placing the to-be-milled and riveted workpiece is mounted in an accompanying tooling rack; a pair of pressing pliers used for fixing the to-be-milled and riveted workpiece is arranged on the accompanying tooling rack; a locator is arranged on one side of the pair of pressing pliers; and an infrared identification sensor which cooperates with the locatorto achieve identification locating is mounted on a station of the numerical control machine tool. According to the machine tool flexible assembly method, the interior of the accompanying tooling rackcan be adjusted to reduce clamping difficulty, and flexibility and processing precision of a production line are improved; and locating is achieved on each hole and detection is achieved on each pin,so that errors generated during processing are effectively decreased, and drilling and milling precision is improved.

Description

technical field [0001] The invention relates to the technical field of flexible clamping, in particular to a method for flexible assembly of machine tools. Background technique [0002] The vertical machining center refers to the machining center with the main shaft in a vertical state. Its structure is mostly a fixed column. The workbench is rectangular and has no indexing and rotating function. It is suitable for processing discs, sleeves, and plate parts. It generally has three linear motions. Coordinate axis, and a rotary table that rotates along the horizontal axis can be installed on the workbench to process spiral parts; after the workpiece is clamped once on the machining center, the CNC system is used to control the machine tool to automatically select according to different processes And change the tool, automatically change the machine tool spindle speed, feed rate and the movement track of the tool relative to the workpiece and other auxiliary functions, complete...

[0002] The vertical machining center refers to the machining center with the main shaft in a vertical state. Its structure is mostly a fixed column. The workbench is rectangular and has no indexing and rotating function. It is suitable for processing discs, sleeves, and plate parts. It generally has three linear motions. Coordinate axis, and a rotary table that rotates along the horizontal axis can be installed on the workbench to process spiral parts; after the workpiece is clamped once on the machining center, the CNC system is used to control the machine tool to automatically select according to different processes And change the tool, automatically change the machine tool spindle speed, feed rate and the movement track of the tool relative to the workpiece and other auxiliary functions, complete the multi-process processing on several surfaces of the workpiece in sequence, and have a variety of tool changing or tool selection functions, so that The production efficiency is greatly improved; however, the clamping parts of conventional CNC machine tools are relatively single, and often only one type can be clamped, which is not suitable for the processing requirements of multiple parts in flexible production lines. At the same time, errors are prone to occur during the processing process, resulting in poor processing accuracy , especially for softer and more variable assembly parts, it is more prone to error
