Embodiment 1

[0031] The first step is to build a workpiece clamping control system with automatic tool avoidance function:

[0032] Measure the length and width of the working platform 1 of the CNC machine tool, which are 2500mm and 2500mm respectively. Carry out area division along the length and width directions of the CNC machine tool working platform 1, among which 10 areas are divided along the length direction, each area is 250mm, and the serial number (1~10) is marked; according to the layout of the trapezoidal groove, the width direction is divided into 10 areas, Each area is 250mm, and the serial number (1~10) is marked. The sum of the divided sub-regions has covered the entire working platform 1 of the CNC machine tool. Establish the CNC machine tool work platform coordinate system 6 under the CNC machine tool work platform 1, and record the length and width range of each sub-region under the coordinate system, for example: the range of the area (1, 2) under the CNC machine tool...

Abstract

The invention discloses an automatic tool avoiding method of a clamping mechanism. The method is characterized in that a flexible tool system with an automatic avoiding function is built by taking anexisting machine tool and numerical control system as a platform; then an existing mounting platform is subjected to area division, coordinates of the clamping mechanism under the current mounting platform are calibrated and input into the system, and a workpiece is clamped through air pressure; in the machining process, the numerical control system reads the coordinate position of a tool, and when the tool reaches the coordinate position of the clamping mechanism, the clamping mechanism automatically releases the workpiece and avoids the tool; and after the tool leaves the coordinate positionof the clamping mechanism, the clamping mechanism returns to the original position and clamps the workpiece again. The method solves the problem of motion interference generated by the tool and the clamping mechanism, is high in reliability and easy to operate, and improves the machining efficiency.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a method for automatically avoiding a tool by a clamping mechanism. Background technique [0002] There are a large number of overall structural parts in the aerospace field, which have the characteristics of long processing cycle, low processing efficiency, difficult processing, and high manufacturing precision requirements. Among them, the design and application of parts tooling has an important impact on ensuring the quality of parts production, improving productivity, and shortening the processing cycle. At present, special tooling is designed for specific types of integral mechanism parts. The manufacturing cost of special tooling is high, the structure size is large, and clamping is difficult. Therefore, a CNC machining unit can only process parts of the same type for a long time, and cannot meet the needs of flexible, flexible and fast replacemen...
