It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0028] In actual applications, before setting the tool of a CNC machine tool, the automatic tool setting instrument needs to be installed at the predetermined position of the CNC machine tool. At present, the automatic tool setting instrument cannot be quickly installed on the CNC machine tool, and the automatic tool setting instrument cannot be quickly accurately positioned, resulting in a long production preparation time, low production efficiency, and a cumbersome tool setting process, which affects the overall processing efficiency and processing quality of the CNC machine tool.

[0029] In view of this, the present application proposes an automatic tool setting device and method to solve the above technical problems.

[0030] See also Figure 1 , is a schematic structural diagram of an automatic tool setting device 100 provided in one embodiment of the present application.

[0031] Specifically, combined Figure 1 and Figure 2 As shown, the automatic tool setting device 100 includes a tool setting instrument 10, a processing machine 20, a plurality of positioning members 30, and a magnetic base 40. The plurality of positioning members 30 are installed on the processing machine 20, and the plurality of positioning members 30 are used to position the tool setting instrument 10. The magnetic base 40 is installed at the bottom of the tool setting instrument 10, and the plurality of positioning members 30 are supported on the magnetic base 40, and the magnetic base 40 is adsorbed on the processing machine 20. Among them, the processing machine 20 can be a horizontal processing machine 20.

[0032] In the above embodiment, by adding a plurality of positioning members 30 to the processing machine tool 20, the precise positioning of the tool setting instrument 10 can be completed in a relatively short time. By adding a magnetic base to the bottom of the tool setting instrument 10, it can be ensured that the tool setting instrument 10 is quickly and firmly installed on the CNC machine tool, thereby effectively shortening the preparation time for automatic tool setting, improving production efficiency, making the tool setting process smoother, and thus improving the overall processing efficiency and processing quality of the CNC machine tool.

[0033] In some embodiments of the present application, the automatic tool setting device 100 may include three positioning members, two of which are supported on the first side C1 of the magnetic base 40 opposite to the tool of the processing machine 20, and one of which is supported on the second side C2 of the magnetic base 40 adjacent to the first side C1, to ensure that the tool setting instrument 10 can be accurately positioned.

[0034] In some embodiments of the present application, the plurality of positioning members 30 may be cylindrical to avoid scratching the magnetic base 40 when the positioning members 30 abut against the magnetic base 40 .

[0035] In some embodiments of the present application, the processing machine tool 20 includes a fixture 21. A plurality of positioning members 30 are installed on one side of the fixture 21, and a magnetic base 40 is adsorbed on the fixture 21, and the fixture 21 is used to fix a workpiece.

[0036] In the above embodiment, the positioning member is installed on one side of the fixture 21, so as to avoid providing an additional fixed platform on the processing machine 20, thereby saving production costs.

[0037] Combination Figure 3 As shown, in some embodiments of the present application, the automatic tool setting device 100 further includes a first plug 50 and a second plug 60. The first plug 50 is electrically connected to the tool setting instrument 10 via a first signal cable 70. The second plug 60 is electrically connected to the processing machine tool 20 via a second signal cable 80, wherein the first plug 50 is adapted to the second plug 60.

[0038] In some embodiments of the present application, the first plug 50 is a male plug, and the second plug 60 is a female plug.

[0039] In some embodiments of the present application, the first plug 50 and the second plug 60 are both seven-core plugs.

[0040] In the above embodiment, the tool setting instrument 10 and the processing machine tool 20 are connected by the first plug 50 and the second plug 60, so that the tool setting instrument 10 and the processing machine tool 20 can be detachably connected, so that one tool setting instrument 10 can correspond to multiple processing machine tools 20, and there is no need to bind one tool setting instrument 10 to one horizontal processing machine tool 20, which greatly saves the tool setting cost. In addition, the tool setting instrument 10 and the processing machine tool 20 can be connected by plugging and unplugging the first plug 50 and the second plug 60, which improves the connection efficiency of the tool setting instrument 10 and the processing machine tool 20 and saves the tool setting preparation time.

[0041] Combination Figure 3 As shown, in some embodiments of the present application, the automatic tool setting device 100 further includes a solenoid valve 90. The solenoid valve 90 is installed on the processing machine 20. The processing machine 20 further includes a probe 22. The solenoid valve 90 is used to control the probe 22 to be opened or closed.

[0042] In the above embodiment, due to the specific equipment properties of the processing machine tool 20, the probe 22 receiver of the processing machine tool 20 is required to read the signal emitted by the sensor. When the probe 22 receiver is working, it will be affected by the probe 22 in the open state inside the processing machine tool 20. Therefore, when the tool setting instrument 10 is working, the present application controls the probe 22 to be closed through the solenoid valve 90, thereby shielding the signal interference of the probe 22, so as to facilitate the probe 22 receiver to read the signal emitted by the sensor, such as the mechanical coordinates of the processing machine tool 20.

[0043] See also Figure 4 , is a schematic diagram of the steps of an automatic tool setting method provided in one embodiment of the present application.

[0044] In some embodiments of the present application, the automatic tool setting method provided by the present application is implemented by the automatic tool setting device 100 of the above embodiment.

[0045] Specifically, the automatic tool setting method includes the following steps. According to different requirements, the order of some steps in the flowchart can be changed, and some steps can be omitted.

[0046] In step S10 , a plurality of cutting tools are installed on the processing machine tool 20 .

[0047] Specifically, before installing a plurality of tools for machining a workpiece on the machining machine 20 , it is necessary to confirm whether the model of each tool is correct. After confirming that the model of the tool is correct, the tool is installed on the machining machine 20 .

[0048] Step S11, obtaining the runout amounts of multiple tools, and determining whether the runout amounts of the tools meet preset control conditions.

[0049] Specifically, the runout of the tool may be determined using a measuring tool, wherein the measuring tool may be a micrometer.

[0050] In some embodiments of the present application, if the deflection of the tool is greater than a preset deflection threshold, for example, 0.010 mm, it means that the tool installation is unstable, that is, the deflection of the tool does not meet the preset control conditions. At this time, it is necessary to return to step S10 and reinstall the tool.

[0051] In some embodiments of the present application, if the runout of the tool is less than or equal to a preset runout threshold, for example, 0.010 mm, it means that the tool installation is stable, that is, the runout of the tool meets the preset control conditions. At this time, continue to execute step S12 to start the automatic mode of the processing machine tool 20.

[0052] Step S12, starting the automatic mode of the processing machine tool 20 and starting a preset automatic tool setting process.

[0053] Specifically, the automatic tool setting process includes: selecting a tool to be calibrated from a plurality of tools, and controlling the processing machine tool 20 to automatically change to the tool to be calibrated; controlling the processing machine tool 20 to automatically move to the reference position of the tool setting instrument 10; starting the tool setting instrument 10, and closing the probe 22 of the processing machine tool 20 through the solenoid valve 90; controlling the X-axis and Y-axis of the processing machine tool 20 to automatically move to the center of the tool setting instrument 10, and controlling the Z-axis of the processing machine tool 20 to automatically move to the first position of the working plane of the tool setting instrument 10; controlling the Z-axis of the processing machine tool 20 to automatically move to the second position of the working plane of the tool setting instrument 10, and slowly moving to the tool setting position. The tool setting instrument 10 is used to move the Z axis of the processing machine tool 20 to the third position of the working plane of the tool setting instrument 10, perform a first detection, and determine the result of the first detection; control the Z axis of the processing machine tool 20 to automatically move to the fourth position of the working plane of the tool setting instrument 10, perform a second detection, and determine the result of the second detection; determine the error between the first detection result and the second detection result; if the error is within the preset error range, calculate the actual length of the tool to be calibrated and the difference between the first detection result and the second detection result, and update the length compensation value of the tool to be calibrated based on the difference; when the tool to be calibrated is completed, control the Z axis of the processing machine tool 20 to automatically return to the origin.

[0054] In some embodiments of the present application, the automatic tool setting process is also used to issue an alarm message if the error is not within a preset error range.

[0055] It should be noted that the specific steps of the automatic tool setting process will be described in the following Figure 5 The corresponding embodiments are described in detail, and to avoid repetition, they will not be described one by one here.

[0056] Step S13, when the automatic tool setting process runs to the preset pause process node and the processing machine tool 20 moves to the predetermined position, the first plug 50 is inserted into the second plug 60, and the tool setting instrument 10 is placed between the multiple positioning members 30, ensuring that the multiple positioning members 30 are against the magnetic base 40, and the magnetic base 40 is adsorbed on the processing machine tool 20.

[0057] Specifically, first, the first plug 50 is inserted into the second plug 60 to achieve a quick connection between the tool setting instrument 10 and the processing machine 20; second, the tool setting instrument 10 is placed between the plurality of positioning members 30 to complete the precise positioning of the tool setting instrument 10 in a relatively short time; then, the tool setting instrument 10 is attached to the processing machine 20 through the magnetic base 40 to ensure that the tool setting instrument 10 is quickly and firmly installed on the CNC machine tool. Based on this, the preparation time for automatic tool setting is effectively shortened, the production efficiency is improved, the tool setting process is made smoother, and the overall processing efficiency and processing quality of the CNC machine tool are improved.

[0058] Step S14, restarting the automatic tool setting process to automatically set the multiple tools in sequence.

[0059] It should be noted that the specific steps of the automatic tool setting process will be described in the following Figure 5 The corresponding embodiments are described in detail, and to avoid repetition, they will not be described one by one here.

[0060] Step S15 , after tool alignment of the plurality of tools is completed, the first plug 50 is pulled out from the second plug 60 .

[0061] Specifically, by unplugging the first plug 50 from the second plug 60, the tool setting probe 10 and the processing machine tool 20 can be disassembled, so that one tool setting probe 10 can correspond to multiple processing machine tools 20. There is no need to bind one tool setting probe 10 to one horizontal processing machine tool 20, which greatly saves tool setting costs.

[0062] The automatic tool setting method of the above embodiment simplifies the tool setting process, improves the tool setting efficiency, and thus shortens the production preparation time. In addition, the technical specialist only needs to press the start button twice to automatically set all tools, which reduces the skill requirements for the technical specialist. Even operators who do not have rich experience can complete the precise tool setting work, reducing the fluctuation of processing quality caused by differences in human skills, making production more stable and reliable.

[0063] See also Figure 5 , is a schematic diagram of the steps of the automatic tool setting process provided in one embodiment of the present application.

[0064] Specifically, the automatic tool setting process includes the following steps. According to different requirements, the order of some steps in the flowchart can be changed, and some steps can be omitted.

[0065] Step S20, selecting a tool to be calibrated from a plurality of tools, and controlling the processing machine tool 20 to automatically switch to the tool to be calibrated.

[0066] Step S21 , controlling the processing machine tool 20 to automatically move to the reference position of the tool setting probe 10 .

[0067] Step S22 , starting the tool setting instrument 10 , and closing the probe 22 of the processing machine tool 20 via the solenoid valve 90 .

[0068] Step S23 , controlling the X-axis and Y-axis of the machining machine 20 to automatically move to the center of the tool setting probe 10 , and controlling the Z-axis of the machining machine 20 to automatically move to a first position of the working plane of the tool setting probe 10 .

[0069] In step S24, the Z axis of the machining center 20 is controlled to automatically move to the second position of the working plane of the tool setting device 10 and to the third position of the working plane of the tool setting device 10, respectively, to perform a first detection and determine the first detection result.

[0070] Step S25, controlling the Z axis of the processing machine tool 20 to automatically move to the fourth position of the working plane of the tool setting probe 10, performing a second detection, and determining the second detection result.

[0071] Step S26, determining the error between the first detection result and the second detection result.

[0072] Step S27, if the error is within the preset error range, respectively calculate the difference between the actual length of the tool to be calibrated and the first detection result and the second detection result, and update the length compensation value of the tool to be calibrated based on the difference.

[0073] In some embodiments of the present application, if the error is not within a preset error range, an alarm message is issued.

[0074] Step S28, after the tool to be calibrated is completed, the Z axis of the processing machine tool 20 is controlled to automatically return to the origin.

[0075] In the above embodiment, accurate measurement of the position between the tool and the workpiece is achieved through a precise algorithm, which effectively eliminates errors caused by human factors and ensures that each cutting of the tool can be performed with an accurate path and depth, thereby significantly improving the dimensional accuracy and surface quality of the workpiece.
