Description

Technical Field

[0001] The invention belongs to the technical field of milling cutters, and in particular relates to a milling cutter. Background Art

[0002] Milling inserts are commonly used tool parts in mechanical processing, and their quality directly affects processing accuracy and efficiency. In actual production, problems such as wear, temperature, and cutting force of milling inserts may lead to processing defects and even cause safety accidents. At present, the inspection of milling inserts mainly relies on manual visual inspection or external measuring tools. The milling inserts themselves do not have a detection function, resulting in low detection accuracy and low efficiency.

[0003] Therefore, further improvements are made to the above problems. Summary of the invention

[0004] The main purpose of the present invention is to provide a milling cutter, which is linked by a strain sensor, a temperature sensor, a wear sensor, a heat dissipation module and a wireless transmission module, so that the milling cutter can detect its own wear, temperature, cutting force and other problems when working, and has the advantages of high precision, intelligence and high efficiency.

[0005] To achieve the above objectives, the present invention provides a milling cutter, comprising a body, a strain sensor, a temperature sensor, a wear sensor, a heat dissipation module and a wireless transmission module, wherein:

[0006] The strain sensor is built into the key stress-bearing parts of the body (such as the cutting edge and the connection between the blade and the body, etc., where the stress changes significantly during the cutting process) and is monitored when the body is working, so as to obtain the strain signal of the body caused by the change of the cutting force, and transmit the strain signal to the background through the wireless transmission module, so that the background obtains the strain data of the body including the size and distribution of the cutting force;

[0007] The temperature sensor is built into a key temperature-rising position of the body (e.g., a position close to the cutting edge to directly measure the heat generated during the cutting process) and is monitored when the body is working, thereby obtaining temperature signals of different parts of the blade, and the temperature signals are transmitted to the background through a wireless transmission module, so that the background obtains temperature data of different parts of the body;

[0008] The wear sensor is externally mounted on the body (wear is detected by laser displacement, and the laser displacement sensor is installed at a position that can be aligned with the cutting edge of the body), and by emitting a laser beam and measuring the time or phase change of the reflected light, the wear amount data of the cutting edge of the body is finally calculated in the background, thereby monitoring the shape and size changes of the cutting edge in real time;

[0009] The heat dissipation module includes a number of heat dissipation channels built into the body. One end of the heat dissipation channel extends to each key temperature-rising part, and the other end of the heat dissipation channel is connected to a cooling medium processing unit located outside the body. The background controls the cooling medium processing unit according to the temperature data, so that the cooling medium processing unit injects the cooling medium into the heat dissipation channel corresponding to the key temperature-rising part that needs heat dissipation treatment, thereby cooling the key temperature-rising part (which can not only reduce the wear of the body, but also prevent deformation caused by excessive temperature and improve the processing accuracy).

[0010] As a further preferred technical solution of the above technical solution, the background judges whether the key stress-bearing part is in a normal working state through the strain data and displays it through the display interface. If it is in a normal working state, the strain monitoring is continued and a normal strain signal is displayed on the display interface; if it is in an abnormal working state of overload or abnormal cutting force, the body work is stopped and a strain abnormal signal is displayed on the display interface (to remind the operator to perform on-site inspection and maintenance, etc.).

[0011] As a further preferred technical solution of the above technical solution, the background judges whether the key temperature-rising part reaches the corresponding matching temperature threshold through the temperature data, where:

[0012] If it does not reach, the temperature monitoring is continued and a normal temperature signal is displayed on the display interface;

[0013] If it reaches, a temperature abnormal signal of the corresponding key temperature-rising part is displayed on the display interface. The cooling medium processing unit injects the cooling medium into the heat dissipation channel corresponding to the key temperature-rising part that needs heat dissipation treatment, thereby cooling the key temperature-rising part; and when the key temperature-rising part continues to rise in temperature due to work and reaches the temperature threshold again (indicating that the previously injected cooling medium can no longer ensure the heat dissipation of the key temperature-rising part), the cooling medium processing unit recovers the previously injected cooling medium (including suction and other operations) and injects a new cooling medium again, thereby cooling the key temperature-rising part again, so that the key temperature-rising part always works below the temperature threshold; if the display interface shows that the key temperature-rising part works for a preset time longer than the temperature threshold, the body work is stopped and a temperature abnormal signal is displayed on the display interface (indicating a fault such as damage to the key temperature-rising part or leakage of the cooling medium, to remind the operator to perform on-site inspection and maintenance, etc.).

[0014] As a further preferred technical solution of the above technical solution, the background judges whether the cutting edge is in a normal working state through the wear amount data and displays it through the display interface. If it is in a normal working state, the wear amount monitoring is continued and a normal wear amount signal is displayed on the display interface, so as to predict the remaining service life; otherwise, a wear amount abnormal signal is displayed on the display interface (to remind the operator to perform on-site inspection and maintenance, etc.).

[0015] As a further preferred technical solution of the above technical solution, the background is wirelessly connected to the wireless transmission module. BRIEF DESCRIPTION OF THE DRAWINGS

The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations. The basic principles defined in the following description of the present invention can be applied to other implementation schemes, variant schemes, improvement schemes, equivalent schemes, and other technical schemes that do not deviate from the spirit and scope of the present invention.

[0018] In the preferred embodiment of the present invention, those skilled in the art should note that the body and the like involved in the present invention can be regarded as the prior art.

[0019] Preferred embodiment.

[0020] As Figure 1 shown, the present invention discloses a milling insert, including a body, a strain sensor, a temperature sensor, a wear sensor, a heat dissipation module, and a wireless transmission module, wherein:

[0021] The strain sensor is built into the key stress-bearing parts of the body (such as the cutting edge, and the connection between the insert and the tool body, etc., where the stress changes significantly during the cutting process) and monitors during the operation of the body, so as to obtain the strain signal caused by the change of the cutting force of the body, and transmit the strain signal to the background through the wireless transmission module, so that the background obtains the strain data including the magnitude and distribution of the cutting force of the body;

[0022] The temperature sensor is built into the key heat-generating parts of the body (such as the position near the cutting edge, directly measuring the heat generated during the cutting process) and monitors during the operation of the body, so as to obtain the temperature signals of different parts of the insert, and transmit the temperature signals to the background through the wireless transmission module, so that the background obtains the temperature data of different parts of the body;

[0023] The wear sensor is externally arranged on the body (wear is detected by laser displacement, and the laser displacement sensor is installed at a position where the cutting edge of the body can be aligned), and by emitting a laser beam and measuring the change in time or phase of the reflected light, finally the wear amount data of the cutting edge of the body is calculated in the background, so as to monitor the change in the shape and size of the cutting edge in real time;

[0024] The heat dissipation module includes a number of heat dissipation channels built into the body. One end of the heat dissipation channel extends to each key temperature-rising part, and the other end of the heat dissipation channel is connected to a cooling medium processing unit located outside the body. The background controls the cooling medium processing unit according to the temperature data, so that the cooling medium processing unit injects the cooling medium into the heat dissipation channel corresponding to the key temperature-rising part that needs heat dissipation treatment, thereby cooling the key temperature-rising part (which can not only reduce the wear of the body, but also prevent deformation caused by excessive temperature and improve the processing accuracy).

[0025] Specifically, the background judges whether the key stressed part is in a normal working state through the strain data and displays it through the display interface. If it is in a normal working state, the strain monitoring is continued and a strain normal signal is displayed on the display interface; if it is in an abnormal working state of overload or abnormal cutting force, the operation of the body is stopped and a strain abnormal signal is displayed on the display interface (to remind the operator to perform on-site maintenance, etc.).

[0026] More specifically, the background judges whether the key temperature-rising part reaches the corresponding temperature threshold through the temperature data, where:

[0027] If it does not reach, the temperature monitoring is continued and a temperature normal signal is displayed on the display interface;

[0028] If it reaches, a temperature abnormal signal of the corresponding key temperature-rising part is displayed on the display interface. The cooling medium processing unit injects the cooling medium into the heat dissipation channel corresponding to the key temperature-rising part that needs heat dissipation treatment, thereby cooling the key temperature-rising part; and when the key temperature-rising part continues to rise in temperature due to work and reaches the temperature threshold again (indicating that the previously injected cooling medium can no longer ensure the heat dissipation of the key temperature-rising part), the cooling medium processing unit recovers the previously injected cooling medium (including suction-back operations, etc.) and injects new cooling medium again, thereby cooling the key temperature-rising part again, so that the key temperature-rising part always works below the temperature threshold; if the display interface shows that the key temperature-rising part works for a preset time longer than the temperature threshold, the operation of the body is stopped and a temperature abnormal signal is displayed on the display interface (indicating that there are faults such as damage to the key temperature-rising part or leakage of the cooling medium, etc., to remind the operator to perform on-site maintenance, etc.).

[0029] Furthermore, the background judges whether the cutting edge is in a normal working state through the wear amount data and displays it through the display interface. If it is in a normal working state, the wear amount monitoring is continued and a wear amount normal signal is displayed on the display interface, so as to predict the remaining service life; otherwise, a wear amount abnormal signal is displayed on the display interface (to remind the operator to perform on-site maintenance, etc.).

[0030] Furthermore, the background is wirelessly connected to the wireless transmission module.

[0031] It is worth mentioning that technical features such as the main body involved in this invention patent application should be regarded as the prior art. For the specific structures, working principles, possible control methods, and spatial arrangement methods of these technical features, conventional selections in the art can be adopted, and they should not be regarded as the invention points of this invention patent. This invention patent will not be further specifically elaborated.

[0032] For those skilled in the art, it is still possible to modify the technical solutions described in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
