TECHNICAL FIELD

[0002] A numerical control machine tool processes parts through a tool, and a milling cutter is a kind of tool, which mainly grinds a workpiece through rotation of the milling cutter. The wear resistance of the milling cutter itself has a great influence on the working performance of the milling cutter. It is necessary to detect the wear resistance of the milling cutter, but the traditional tool wear performance detection equipment has certain defects.
[0003] For example, the tool is often affected by various environmental conditions such as temperature, humidity, and pressure in actual work, but the current tool wear detection equipment basically cannot simulate the real environment to enable manufacturers and users to accurately evaluate the performance of the tool in actual use and make corresponding improvements or adjustments. In addition, the traditional tool wear detection equipment uses tool rotation grinding when detecting the wear of the milling cutter. This grinding method has poor wear effect on the milling cutter, and it takes several hours to complete a grinding experiment. At the same time, the parts used for grinding in the detection equipment are very easy to damage. The milling cutter treated by annular synchronous wear is not conducive to wear comparison with itself, and a comparison template also needs to be set.
[0004] Finally, the conventional grinding device is easy to leave scratch grooves on itself when grinding the milling cutter. With the continuous grinding, the depth of the scratch grooves is continuously accumulated, which will affect the service life of the grinding equipment on the one hand, and will also affect the wear effect on the other hand.
[0005] The conventional detection equipment mainly compares through industrial camera shooting, but the surface of the milling cutter is very smooth after grinding, which is easy to reflect light and will affect the clarity of the industrial camera shooting photos, thereby affecting the detection result.

The water jet pipe of the present application sprays water flow to the friction position, and the water flow flows through the gap between the friction block and the milling cutter. The scratch groove on the surface of the friction block becomes a water flow channel. On the one hand, the water flow hinders the debris from moving to the friction area, and on the other hand, the water flow is distributed in the scratch groove on the surface of the friction block. The flow through the scratch groove is more, and the heat absorbed is more. The deformation of the scratch groove due to heating and pressure is reduced, and the difference between the scratch groove and other positions is reduced. Through this setting, the damage to the friction block in the process of simulating wear is further reduced, and the incremental cooling speed can also avoid the structural damage to the friction block caused by the large-area contact of the cold air flow in the initial cooling stage.

[0015] Compared with the prior art, the present application has the following advantages: compared with the current tool wear performance detection device, the polishing assembly greatly improves the uniformity of the wear of the friction block surface, thereby improving the service life of the friction block, and also enables the friction block to be more flat after work, providing a good foundation for subsequent detection, in addition, the polishing assembly in the present application has an environment simulation function, which simulates the working state of the tool under different environments, so that manufacturers and users can accurately evaluate the performance of the tool in actual use and make corresponding improvements or adjustments.

The water flow sprayed by the water pipe of the present application is directed to the friction position, the water flow flows through the gap between the friction block and the milling cutter, and the scratch groove on the surface of the friction block becomes a water flow channel. On the one hand, the water flow hinders the debris from moving to the friction area, and on the other hand, the water flow is differentially distributed on the surface of the friction block due to the existence of the scratch groove. More fluid flows through the scratch groove, and more heat is absorbed. The deformation amount of the scratch groove region is reduced due to heating and pressure, and the difference between the scratch groove and other positions is reduced. The detection assembly of the present application utilizes the secondary use of polishing debris to concentrate small particles of debris in the center position of the detection box, and the milling cutter adsorbs the debris powder by attaching a negative charge to the surface. These debris powders increase the roughness of the milling cutter surface, especially the position of the milling cutter surface just after polishing. The rough milling cutter surface diffusely reflects the light of the fill light, making the photos taken by the industrial camera clearer. By comparing the polishing position and the symmetrical position of the milling cutter in the picture using pixel point distribution, the wear of the milling cutter can be accurately calculated.

The debris passes through the milling cutter from the scratch groove, and the scratch groove is deformed by being extruded. If the debris falls off subsequently, the friction effect at this position will be worse than that at other positions. The water flow sprayed by the water jet pipe 168 of the present application is arranged to point to the friction position. The water flow passes through the gap between the friction block 163 and the milling cutter. The scratch groove on the surface of the friction block 163 becomes a water flow channel. On the one hand, the water flow hinders the debris from being rubbed along with the rotation. On the other hand, the water flow is distributed in different amounts on the surface of the friction block due to the existence of the scratch groove. The flow passing through the scratch groove is more, and the heat absorbed is more. Therefore, the deformation amount of the scratch groove region due to heating and pressure is reduced, and the difference between the scratch groove and other positions is reduced. Through the arrangement of the present application, the damage to the friction block 163 in the process of simulating wear is further reduced, and the incremental cooling speed can also avoid the structural damage to the friction block 163 caused by the large-area contact of the cold airflow in the initial cooling stage. The structure is matched with the conveying belt type friction structure, which greatly prolongs the service life of the detection equipment.
