Description

Technical Field

[0001] The invention relates to the technical field of tool detection, and in particular to a tool full life cycle wear data collection auxiliary device. Background Art

[0002] Manufacturing is the foundation of the national economy, and CNC machine tools are the core of basic manufacturing capabilities. If the key components of CNC machine tools fail, the processing efficiency of the machine tools will be directly reduced. Therefore, it is particularly important to monitor the status and evaluate the performance of key components. As the "teeth" of CNC machine tools, the health of the tool directly affects the processing efficiency and product quality of the machine tools. The wear data of the tool throughout its life cycle is the basis for tool failure prediction and health management.

[0003] Tool wear data collection mainly includes the maximum VB value of the main flank, the VB value at 1 / 2ap (back cutting amount) of the main flank, the SVB value of the main flank, the maximum VB value of the secondary flank, and the SVB value of the secondary flank. Taking a four-edge milling cutter as an example, five indicators need to be collected for each pair of workpieces processed by the milling cutter. During the collection process, the milling cutter needs to be rotated, raised and lowered in the horizontal and vertical states respectively, and the process is complicated and cumbersome.

Therefore, there are the following disadvantages: manual adjustment and collection are prone to human errors, the degree of automation is low, and the accuracy of tool wear data over its entire life cycle is poor.

The clamping force of the tool clamping jaws 21 is maintained by the clamping jaw spring 25, which improves the clamping stability and can clamp and fix tools of different sizes, further improving the convenience and efficiency of operation.
