Problems solved by technology

In order to solve the problem of tool size caused by human factors, tool setting instruments are mostly used to detect the correctness of tools. At present, for large-stroke translational axis aviation special equipment, the tool measuring method is to install the tool setting instrument on the periphery of the equipment and fix it. Position, in the process of tool measurement, the translation axis needs to reciprocate and measure the tool size at a long distance, which wastes a lot of time moving between the part processing position and the tool setting instrument, which is not conducive to the improvement of processing efficiency, and also increases the operation interference collision risk

Abstract

The invention belongs to the technical field of tool setting detection, and specifically relates to a tool setting detection method of a machine tool. By installing a tool setting instrument and a tool setting instrument tooling above the column of the machine tool, a special tool setting instrument detection method is formulated, and the tool setting function near the tool is realized. , and use the contact tool setting instrument to realize the high-efficiency and high-quality detection of the tool, which can quickly detect the problem of tool setting due to frequent tool changes and adjustment of the tool size in tool processing, and predict the tool size before starting machining to prevent There is a problem with the size of the processing tool that causes the processing quality. The invention improves the traditional structure, can quickly increase the detection speed of tool setting, prevents problems such as wrongly holding, misadjusting, and misinstalling tools, and improves the risk management and control of processing quality.

Description

technical field [0001] The invention belongs to the technical field of tool setting detection, and in particular relates to a tool setting detection method of a machine tool. Background technique [0002] In the process of digital processing of large parts of aviation aircraft, large-scale horizontal aviation special equipment is a common structural form in processing. It is mainly used for boring and milling of large parts. Multiple manual confirmations are required, and the correctness of the tool size is the key to component processing. In order to solve the problem of tool size caused by human factors, tool setting instruments are mostly used to detect the correctness of tools. At present, for large-stroke translational axis aviation special equipment, the tool measuring method is to install the tool setting instrument on the periphery of the equipment and fix it. Position, in the process of tool measurement, the translation axis needs to reciprocate and measure the too...
