Description

Technical Field

[0001] The invention belongs to the technical field of tool processing equipment, and in particular relates to a tool passivation measurement integrated device and a use method thereof. Background Art

[0002] The main processing method in mechanical manufacturing is cutting, and the tool is an indispensable hardware for cutting. Through a high-power magnifying glass, it is found that there are a large number of microscopic notches with a width of 10 to 50 μm on the cutting edge of the tool that is ground by a grinder and a grinding wheel. These microscopic notches not only reduce the surface quality and strength of the tool, but also expand and extend the microscopic notches on the surface of the tool under the influence of multiple factors such as force, heat and vibration in the cutting process, resulting in rapid wear and tear of the tool, which will greatly reduce the service life of the tool and make it difficult to ensure the processing quality of the workpiece. How to reduce or reduce the grinding damage at the cutting edge of the tool is crucial to improving the cutting performance of the tool.

[0003] The emerging tool passivation technology is an effective measure to increase tool life and reduce tool wear. Tool passivation not only eliminates the microscopic defects of the tool edge, but also obtains appropriate microscopic geometric parameters of the edge and a smooth edge surface. At the same time, it eliminates the residual tensile stress on the edge surface caused by grinding, effectively improves the edge strength and the stability of the cutting process, and extends the tool life. Through a large number of cutting tests and edge passivation practices, it is realized that having a good edge shape and edge passivation quality is also a prerequisite for whether the tool can perform cutting processing quickly, efficiently and economically.

[0004] With the development of modern manufacturing technology, the geometry of the cutting edge of the tool may need to be adjusted according to the tool material and the workpiece material, and specific cutting edges are designed according to different cutting processes. The tool passivation machine realizes the scientific passivation treatment of the tool edge, so that the edge is improved to a smooth, regular straight line or curve, thereby increasing the average service life of the tool by 1.5-3 times. In the tool passivation production process, the drag passivation method is more commonly used. Generally, the tool is first clamped on the tool passivation machine for passivation. During the passivation process, disordered friction is generated between the workpiece and the abrasive. Then the tool is taken to the measuring equipment to measure its passivation result. The obtained data is used to characterize the edge geometry. In order to achieve a better passivation effect, a large number of reciprocating operations are required, which not only increases the cumulative error of the measurement, but also increases the production cost of the tool, while reducing the tool production efficiency. Summary of the invention

[0005] The technical problem to be solved by the present invention is that the accuracy of tool passivation processing is difficult to ensure and the cumulative measurement error is large. A tool passivation measurement integrated device and its use method are provided to achieve the purpose of completing passivation and measurement with a single device.
