Description

Technical Field

[0001] The invention relates to the technical field of slotting machines, and in particular to an electrical control system and method for detecting tool wear of slotting machines. Background Art

[0002] A slotting machine is a machine tool used for metal processing. It is mainly used to slot specific shapes of grooves on metal sheets. Before the metal sheets are bent, the slotting machine is used to slot V-shaped or U-shaped grooves at the parts of the sheets that need to be bent.

[0003] However, for the existing slotting machines, there are generally two ways to detect the wear of the cutter head. One is to measure the formed sheet to confirm whether the cutter needs to be realigned or replaced, but this detection method will result in the scrapping of a sheet. The other is to realign the cutter after each period of work, but this will result in low work efficiency.

[0004] In view of the above problems, the present invention adds a tool wear detection device to the slotting machine, which can perform touch detection on each tool; when the tool is worn, the tool is directly compensated to avoid re-calibration. This device not only improves work efficiency, but also avoids the waste of plates. Summary of the invention

[0005] The purpose of the present invention is to solve the problems in the prior art and to provide an electrical control system and method for detecting tool wear of a slotting machine.

[0007] Three knives are installed on the output slides of the Z-axis linear module and the W-axis linear module. The height installation positions of the three knives of the Z-axis and the W-axis are different. Each knife has a difference. The first knife is at the highest position and the third knife is at the lowest position. The third knife is the final position that determines the groove depth. Therefore, the compensation value of the knife can only be set according to the third knife.

[0008] Also includes the following components;

[0009] The motion controller converts the predetermined control scheme and planning instructions into the desired mechanical motion to achieve precise command control. The motion controller is electrically connected to the Z-axis linear module, the W-axis linear module, and the P-axis linear module;

[0010] The human-machine interface is used for displaying text or graphics and has the function of inputting user requirements to realize information interaction between humans and machines. The human-machine interface is used to receive command information sent by the motion controller and upload user requirement information to the motion controller. The motion controller is electrically connected to the human-machine interface;

[0011] Tool setting instrument, used to detect the quality of the tool and upload the tool detection results to the judgment module. The tool setting instrument is fixedly installed on the output slide of the P-axis linear module;

[0012] A three-color light, used to receive command information from the motion controller and intuitively display the detection results of the tool, the three-color light is electrically connected to the motion controller;

[0013] A judgment module is used to receive the tool detection result in the motion controller and judge whether the error range of the tool is within the set range of the system. The judgment module uploads the judgment result to the motion controller. The motion controller receives the tool judgment result and controls the three-color light to light up according to the tool judgment result.

[0014] The alarm module is used to receive the command information alarm issued by the motion controller. The alarm module is electrically connected to the motion controller.

[0015] The tool compensation module is used to receive the tool judgment result in the judgment module, calculate the tool compensation value and upload it to the motion controller;

[0016] The monitoring module is fixedly installed on the slotting machine body with the monitoring end facing the position of the Z-axis linear module, the W-axis linear module and the P-axis linear module, and is used to monitor the position information of the Z-axis linear module, the W-axis linear module and the P-axis linear module.

[0017] Furthermore, the Z-axis linear module includes a Z-axis driver and a Z-axis motor, and the Z-axis driver and the Z-axis motor are fixedly mounted on the slotting machine body, the output end of the Z-axis driver is fixedly connected to the driving end of the Z-axis motor, and the motion controller is electrically connected to the Z-axis driver.

[0018] Furthermore, the W-axis linear module includes a W-axis driver and a W-axis motor, and the W-axis driver and the W-axis motor are both fixedly mounted on the slotting machine body, the output end of the W-axis driver is fixedly connected to the driving end of the W-axis motor, and the motion controller is electrically connected to the W-axis driver.

[0019] Furthermore, the P-axis linear module includes a P-axis driver and a P-axis motor, and the P-axis driver and the P-axis motor are fixedly installed on the slotting machine body, the output end of the P-axis driver is fixedly connected to the driving end of the P-axis motor, and the motion controller is electrically connected to the P-axis driver.

[0020] Furthermore, the three-color light includes a red light, a green light and a yellow light;

[0021] The control method of the red light, green light and yellow light is as follows: if the judgment module detects that the errors of the three tools on the Z axis and the three tools on the W axis are within the system setting range and the tools do not need to be compensated, the green light will be on;

[0022] If the judgment module detects that the errors of the three tools on the Z axis and the three tools on the W axis are both within the system setting range but the tools need to be compensated, the yellow light will be on;

[0023] If the judgment module detects that the error of the three tools on the Z axis or any of the three tools on the W axis is not within the error range set by the system, the red light will turn on.

[0024] Furthermore, the judgment method of the judgment module is:

[0025] If the error values ​​of the three Z-axis tools and the three W-axis tools are within the range set by the system, the judgment module uploads the error values ​​of the three Z-axis tools and the three W-axis tools to the tool compensation module to calculate the tool compensation value of the corresponding tool;

[0026] If the error value of any of the three Z-axis tools or the three W-axis tools is outside the range set by the system, the judgment module will upload the judgment result to the motion controller, and the motion controller will send an IO signal to the three-color light, the red light will turn on, and the motion controller will control the alarm module to alarm. The motion controller will upload the position and error value of the corresponding tool to the human-machine interface and display it, reminding the operator to change the tool.

[0027] Furthermore, the alarm module is a buzzer.

[0028] Furthermore, the monitoring module is a high-definition camera.

[0029] In order to better achieve the purpose of the present invention, the present invention also provides a method for detecting wear of a slotting machine tool, comprising the following steps:

[0030] Step 1: The motion controller sends a pulse command to the P-axis linear module. The output slider of the P-axis linear module starts to drive the tool setter to move to the left. When the monitoring module detects that the tool setter has moved to the F point, the monitoring module uploads the position information of the tool setter to the motion controller, and the motion controller commands the P-axis linear module to stop.

[0031] Step 2: The motion controller sends a pulse command to the Z-axis linear module. The output slider of the Z-axis linear module drives the three Z-axis tools to start moving downward. When the first Z-axis tool touches the sensing plane on the tool setting instrument, the tool setting instrument sends a signal to the motion controller. The motion controller receives the signal and commands the Z-axis linear module to stop moving.

[0032] Step 3: The motion controller confirms the error value of the first tool of the Z axis according to the stop position of the output slider of the Z axis linear module and the position of the tool setting instrument;

[0033] Step 4: Move the tool setting instrument to the E and D points in turn, repeat the above steps to detect the remaining two tools of the Z axis and determine the error values ​​of the remaining two tools of the Z axis;

[0034] Step 5: The tool setting instrument moves to the C point position, and the motion controller sends a pulse command to the W-axis linear module. The output slider of the W-axis linear module drives the three W-axis tools to start moving downward. When the first W-axis tool touches the sensing plane on the tool setting instrument, the tool setting instrument sends a signal to the motion controller. The motion controller receives the signal and commands the W-axis linear module to stop. The motion controller confirms the error value of the first W-axis tool according to the stop position of the output slider of the W-axis linear module and the position of the tool setting instrument.

[0035] The tool setting instrument moves to the positions of point B and point A in turn, and repeats the above steps to detect the remaining two tools of the W axis and determine the error values ​​of the remaining two tools of the W axis;

[0036] Step 6: The motion controller uploads the error values ​​of the three Z-axis knives and the three W-axis knives to the judgment module for error range judgment;

[0037] Step 7: The judgment module uploads the errors of the three tools on the Z axis and the judgment results of the three tools on the W axis to the motion controller and the tool compensation module. The motion controller controls the three-color light to light up according to the judgment results.

[0038] Step 8: The tool compensation module receives the error values ​​of the third tool of the Z axis and the third tool of the W axis in the judgment module, and then calculates the tool compensation values ​​of the third tool of the Z axis and the third tool of the W axis, the tool compensation value = tool error value, and then the tool compensation module inputs the tool compensation values ​​of the third tool of the Z axis and the third tool of the W axis into the motion controller;

[0039] Step 9: The motion controller receives the tool compensation values ​​of the third tool of the Z-axis and the third tool of the W-axis and sends a pulse command to the Z-axis linear module and the W-axis linear module. The output slider of the Z-axis linear module drives the three Z-axis tools to start moving downward. When the length of the three Z-axis tools moving downward is the tool compensation value of the third Z-axis tool, the motion controller controls the Z-axis linear module to stop.

[0040] The output slider of the W-axis linear module drives the three W-axis tools to start moving downward. When the length of the three W-axis tools moving downward is the tool compensation value of the third W-axis tool, the motion controller controls the W-axis linear module to stop.

[0041] Step 10: Compensation of three tools on the Z axis and three tools on the W axis is completed.

[0042] When the present invention is in use, the motion controller sends a control instruction to the P-axis linear module, the P-axis linear module controls the tool setting instrument to move to the instruction point to detect the tool, and the tool setting instrument then uploads the detection result to the judgment module, and the judgment module judges whether the detection results of multiple points are within the error range of the system. If they are within the error range, the judgment module uploads the judgment result to the tool compensation module, so that the motion controller controls the Z-axis linear module or the W-axis linear module to compensate the tool; if they are not within the error range, the judgment module uploads the judgment result to the motion controller, and the motion controller controls the three-color light and the alarm module to alarm.

[0043] The present invention realizes the function of touch detection of each knife through the tool setting instrument, and can compensate the tool according to the detection result to avoid re-setting the tool. The device not only improves the work efficiency, but also avoids the waste of plate materials, and realizes the functions of monitoring, compensating and alarming for worn tools.

[0080] Embodiment 2: In some embodiments, Figure 1-Figure 2 As shown, as a preferred embodiment of the present invention, the slotting machine body 1 is tested when it is turned on, and a total of 6 knives on the Z axis and the W axis are tested by the tool setting instrument 7.

[0081] A method for detecting tool wear of a slotting machine comprises the following steps:

[0082] Step 1: The motion controller 2 sends a pulse command to the P-axis linear module 6, and the output slider of the P-axis linear module 6 starts to drive the tool setting instrument 7 to move to the left. When the monitoring module 12 detects that the tool setting instrument 7 moves to the F point position, the monitoring module 12 uploads the position information of the tool setting instrument 7 to the motion controller 2, and the motion controller 2 commands the P-axis linear module 6 to stop the action;

[0083] Step 2: The motion controller 2 sends a pulse command to the Z-axis linear module 4. The output slider of the Z-axis linear module 4 drives the three Z-axis tools to start moving downward. When the first Z-axis tool touches the sensing plane on the tool setting instrument 7, the tool setting instrument 7 sends a signal to the motion controller 2. The motion controller 2 receives the signal and commands the Z-axis linear module 4 to stop the action.

[0084] Step 3: The motion controller 2 confirms the error value of the first tool of the Z axis according to the stop position of the slider output by the Z axis linear module 4 and the position of the tool setting instrument 7;

[0085] Step 4: The tool setting instrument 7 moves to the positions of points E and D in turn, and repeats the above steps to detect the remaining two tools of the Z axis and determine the error values ​​of the remaining two tools of the Z axis;

[0086] Step 5: The tool setting instrument 7 moves to the position of point C, and the motion controller 2 sends a pulse command to the W-axis linear module 5. The output slider of the W-axis linear module 5 drives the three W-axis tools to start moving downward. When the first W-axis tool touches the sensing plane on the tool setting instrument 7, the tool setting instrument 7 sends a signal to the motion controller 2. The motion controller 2 receives the signal and orders the W-axis linear module 5 to stop. The motion controller 2 confirms the error value of the first W-axis tool according to the stop position of the output slider of the W-axis linear module 5 and the position of the tool setting instrument 7.

[0087] The tool setting instrument 7 moves to the positions of point B and point A in turn, and repeats the above steps to detect the remaining two tools of the W axis and determine the error values ​​of the remaining two tools of the W axis;

[0088] Step 6: The motion controller 2 uploads the error values ​​of the three Z-axis knives and the three W-axis knives to the judgment module 10 for error range judgment;

[0089] Step 7: The judgment module 10 uploads the errors of the three tools on the Z axis and the judgment results of the three tools on the W axis to the motion controller 2 and the tool compensation module 11, and the motion controller 2 controls the three-color light 8 to light up according to the judgment results;

[0090] Step 8: The tool compensation module 11 receives the error values ​​of the third tool of the Z axis and the third tool of the W axis in the judgment module 10, and then calculates the tool compensation values ​​of the third tool of the Z axis and the third tool of the W axis, the tool compensation value = the tool error value, and then the tool compensation module 11 inputs the tool compensation values ​​of the third tool of the Z axis and the third tool of the W axis into the motion controller 2;

[0091] Step nine: the motion controller 2 receives the tool compensation values ​​of the third tool of the Z-axis and the third tool of the W-axis and sends a pulse command to the Z-axis linear module 4 and the W-axis linear module 5. The output slider of the Z-axis linear module 4 drives the three Z-axis tools to start moving downward. When the length of the three Z-axis tools moving downward is the tool compensation value of the third Z-axis tool, the motion controller 2 controls the Z-axis linear module 4 to stop.

[0092] The output slider of the W-axis linear module 5 drives the three W-axis tools to start moving downward. When the length of the three W-axis tools moving downward is the tool compensation value of the third W-axis tool, the motion controller 2 controls the W-axis linear module 5 to stop.

[0093] Step 10: Compensation of three tools on the Z axis and three tools on the W axis is completed.

[0094] Embodiment 3: Figure 3 As shown, as a preferred embodiment of the present invention, when the slotting machine body 1 is running, a time variable is set in the motion controller 2. When the slotting machine body 1 is tested every time it runs for a period of time, only the tool probe 7 needs to test the third tool of the Z axis and the W axis.

[0095] There are two reasons for detecting the third knife:

[0096] First of all, there is the problem of wear. Since the three knives of the Z-axis and W-axis of the slotting machine body 1 are installed at different heights, each knife differs by 15 wires, the first knife is at the highest position, and the third knife is at the lowest position. When slotting, as the slot depth accumulates, the depth of each cut will decrease, so that at the end of the slotting, only the third knife is being used, so the third knife is the most worn.

[0097] The second is the issue of efficiency. Each inspection takes time. If the third knife does not need to be replaced, then the other two knives do not need to be replaced either.

[0098] If the tool setting instrument 7 detects that the third tool needs to be replaced, a tool setting block is placed under the three tools, and then the corresponding Z-axis linear module 4 or W-axis linear module 5 is driven to move the tool downward to the observation position and contact the tool setting block. The wear of the tool head is observed by the naked eye. If the tool head is severely worn, it is replaced. This operation will save a lot of time.

[0099] The three knives correspond to three positions on the knife block, and the three positions are 15 degrees apart, which just corresponds to the height of the three knives.

[0100] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made according to the content of the patent application scope of the present invention should belong to the technical scope of the present invention.
