Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In the field of numerically controlled machine tool processing, the spindle unit is the most important component of the machine tool parts, and therefore it is extremely important to efficiently and accurately detect the operation state of the spindle unit. In the related art, the load of the spindle unit is detected through an abnormal load detection function in a numerical control system program, and when the load detection value exceeds a set maximum load threshold value, the numerical control system alarms and the operation of the machine tool is interrupted. However, the threshold value set in the abnormal load detection function provided by the numerical control system is not a direct spindle load value, but a variable which is in linear relation with the spindle load value, and the situation of the spindle load value cannot be intuitively reflected; in addition, when the threshold value set in the abnormal load detection function is smaller, false alarm can occur, and when the set threshold value is larger, the alarm sensitivity is reduced, so that a main shaft and a cutter cannot be effectively protected, and the accuracy is low; in addition, the abnormal load detection function needs to change system parameters when the threshold value is set, and needs to record parameter numbers, so that the abnormal load detection function is complex and inconvenient to operate. In the related art, the main shaft load detection function is realized by using auxiliary codes, the main shaft load detection is started by adding a first auxiliary code in a processing program, the overload multiplying power of the main shaft load is set by adding a second auxiliary code, and the main shaft load monitoring is realized by a PLC program of a numerical control system, however, the method needs to write the codes into the processing program, the requirements on programmers are high, the processing capacity of the needed PLC program is high, and the scanning period of the PLC is long, so that the operation is slow.
Therefore, the embodiment of the invention provides a spindle load monitoring method, which is characterized in that different first load thresholds are set for all cutters, and the spindle load value and the first load threshold are compared through a macro actuator so as to monitor the spindle load, so that the effects of good accuracy and high efficiency are achieved.
According to an embodiment of the present invention, there is provided a spindle load monitoring method embodiment, it being noted that the steps shown in the flowchart of the drawings may be performed in a computer system such as a set of computer executable instructions, and, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in an order other than that shown or described herein.
In this embodiment, a method for monitoring a spindle load is provided, which may be used in an industrial personal computer, a numerical control system, etc., fig. 1 is a flowchart of a method for monitoring a spindle load according to an embodiment of the present invention, as shown in fig. 1, where the flowchart includes the following steps:
step S101, the tool number is read.
In an actual application scene, the numerical control machine tool processes workpieces with different materials and processing requirements through tools with different types, so that when the spindle load is monitored, the number of the tool needs to be read first to acquire the type of the tool corresponding to the number of the tool.
Step S102, acquiring a spindle load value read by the PLC and a first load threshold corresponding to the cutter number.
Because different spindle load values can be generated when different types of cutters are operated, corresponding first load thresholds are preset for each cutter number in a numerical control system of the numerical control machine tool, and the first load thresholds can be selected according to experience or actual detection results. It should be noted that, the function of the PLC itself is used to read the spindle load value, and the PLC can read the spindle load value directly, unlike the variable which is linearly related to the spindle load value and is read by the abnormal load detection function in the related art, so that the method is more accurate.
Step S103, inputting the spindle load value into a macro actuator, and comparing the spindle load value with the first load threshold by the macro actuator. And when the spindle load value exceeds the first load threshold value, receiving an early warning signal transmitted by the macro actuator through the PLC and giving an alarm.
The macro executor is one small application in the numerical control system and is used to execute the instructions written in macro language. Instructions for comparing the spindle load value to the first load threshold may be written in a macro language and executed by a macro executor. Because the macro executor is simple in structure, the macro executor is fast in operation and high in efficiency when executing the comparison instruction. And when the result of the macro executor executing the instruction is that the spindle load value exceeds the first load threshold value, an early warning signal is sent to the PLC. After receiving the early warning signal, the PLC alarms to the user through the alarm function of the PLC.
According to the spindle load monitoring method, the direct spindle load value is read through the PLC, the method is visual, different first load thresholds are set for different cutters, the pertinence is high, the comparison of the spindle load value and the first load threshold is carried out through the macro-actuator, the operation is fast and efficient, and the accuracy and the efficiency are good when the spindle load monitoring is achieved.
In this embodiment, a method for monitoring a spindle load is provided, which may be used in an industrial personal computer, a numerical control system, etc., fig. 2 is a flowchart of a method for monitoring a spindle load according to an embodiment of the present invention, as shown in fig. 2, where the flowchart includes the following steps:
step S201, in response to a configuration operation by a user, a user interface for performing parameter configuration is generated.
The user interface is provided with a parameter input text box through which a desired parameter can be input.
Step S202, responding to the parameter input operation of the user, and acquiring the cutter numbers corresponding to the cutters recorded by the user.
In an actual application scene, different procedures are performed through a plurality of cutters, and the corresponding spindle load values may be different when each cutter performs operation, so that different parameters need to be recorded for different cutters. A parameter input text box may be set for each tool through the user interface and a tool number corresponding to each tool may be input. Further, a spindle load monitoring function switch corresponding to each tool number may be provided, the spindle load monitoring function switch being for indicating an on/off state of the corresponding tool, the corresponding tool being operable only when the spindle load monitoring function switch is in the on state. The user can adjust the on/off state of the corresponding cutter by clicking the main shaft load monitoring function switch.
Step S203, in response to a preset setting operation of the user, obtains a first load threshold and a second load threshold corresponding to the inputted tool number of each tool based on the model number and the participating process of the user.
A parameter input text box for inputting a first load threshold value and a second load threshold value may be set for each tool number, respectively, and the first load threshold value and the second load threshold value corresponding to the tool number are input. The first load threshold is used for indicating a limit value of the spindle load when the spindle runs safely, namely if the spindle load value reaches the first load threshold, an alarm is required to remind a user that the spindle load value reaches the safe running limit value, and adjustment is required to properly reduce the spindle load value. The second load threshold is used for indicating the maximum limit value of the spindle load when the spindle operates, namely, if the spindle load value reaches the second load threshold, the spindle needs to be stopped directly and an alarm is given to remind a user of machine checking and maintenance and the like. The first load threshold and the second load threshold corresponding to the tool number may be selected according to an actual measurement value or an empirical value.
Further, a judgment rule may be preset to judge whether the parameters input by the user meet the specifications. Optionally, a judgment rule for the cutter number is preset, after each cutter number input by a user is received, background data calculation is performed, whether the cutter number input by the user accords with the preset number rule is judged, if not, an error prompt is popped up on the user interface to remind the user that the cutter number input by the user is wrong, and the user needs to input again. For example, the numbering rule is a five-digit numerical code, and a user can pop up a wrong report when inputting digits or letters. Further, a judgment rule for the first load threshold value and the second load threshold value may be preset. When a first load threshold value and a second load threshold value which are input by a user and correspond to the cutter number are received, background data calculation is carried out, and whether the first load threshold value and the second load threshold value are reasonable or not, for example, whether the first load threshold value and the second load threshold value are matched with the cutter number or whether the first load threshold value and the second load threshold value are too large or too small is judged. If the first load threshold value and the second load threshold value are not reasonable, an error prompt is popped up on the user interface so as to remind the user that the first load threshold value and the second load threshold value input are not reasonable. Through setting the user interface, the user can conveniently carry out parameter configuration, and through presetting the judging rule, the purpose of machine error correction can be realized when the user carries out parameter configuration, and the user experience and the accuracy of main shaft load monitoring are further improved.
Step S204, reading the cutter number.
When spindle load monitoring is performed, the tool number needs to be read first to determine a first load threshold value and a second load threshold value corresponding to the tool number. It should be noted that only one tool is typically operated in one machine tool at a time.
Step S205, detecting whether a main shaft load monitoring function switch is turned on; when the main shaft load monitoring function switch is turned on, the normal start of the main shaft load monitoring is determined.
Wherein, each cutter number corresponds to be provided with main shaft load monitoring function switch. The description in step S202 is omitted here.
Step S206, when the main shaft load monitoring function switch is turned on, detecting whether the read tool number is consistent with the tool number corresponding to the turned-on main shaft load monitoring function switch; and when the read tool number is consistent with the tool number corresponding to the opened main shaft load monitoring function switch, determining that the main shaft tool to be started is normally started.
Only when the read tool number is consistent with the tool number corresponding to the opened main shaft load monitoring function switch, the currently used tool can be indicated to correspond to the currently performed main shaft load monitoring, namely, the first load threshold value and the second load threshold value corresponding to the main shaft load monitoring performed at the moment correspond to the currently used tool, so that the correct main shaft load monitoring can be performed.
Step S207, detecting whether the main shaft is working; when the main shaft is working, the main shaft is determined to be in a normal working state.
The normal spindle load value is generated when the spindle is in the normal working state, so that whether the spindle is in the normal working state or not needs to be detected first.
Step S208, acquiring a spindle load value read by the PLC and a first load threshold corresponding to the cutter number.
Please refer to step S102 in the embodiment shown in fig. 1 in detail, which is not described herein.
Step S209, inputting the spindle load value into a macro actuator, and comparing the spindle load value with the first load threshold by the macro actuator. And when the spindle load value exceeds the first load threshold value, receiving an early warning signal transmitted by the macro actuator through the PLC and giving an alarm.
Please refer to step S103 in the embodiment shown in fig. 1 in detail, which is not described herein.
Step S2010, comparing the main shaft load value with a second load threshold value through a macro actuator, and when the main shaft load value exceeds the second load threshold value, receiving an early warning signal transmitted by the macro actuator through a PLC and performing alarm and stop control.
The second load threshold is greater than the first load threshold. The description of the first load threshold and the second load threshold may refer to step S203, and will not be repeated here.
When the spindle load value reaches the second load threshold value, it is indicated that the spindle load value reaches the maximum limit value, which may cause damage to the machine tool, so that not only an alarm, but also an immediate shutdown is required to protect the machine tool.
Optionally, when the read cutter number changes, an alarm signal is sent out and the machine is stopped. If the number of the cutter is read to change, the cutter is changed or the system fails, so that the on-going spindle load monitoring is not necessarily correct, and the machine is stopped and an alarm signal is sent to a user.
According to the spindle load monitoring method, the direct spindle load value is read through the PLC, the method is visual, different first load thresholds are set for different cutters, the pertinence is high, the comparison of the spindle load value and the first load threshold is carried out through the macro-actuator, the operation is fast and efficient, and the accuracy and the efficiency are good when the spindle load monitoring is achieved.
And a second load threshold corresponding to the maximum limit value of the spindle load value is set, so that the machine tool can be stopped and early-warned to a user when the spindle load value reaches the second load threshold, and the machine tool is ensured not to be damaged due to the fact that the spindle load value exceeds the maximum limit value.
And through setting up user interface, the user of being convenient for carries out parameter configuration, through obtaining the cutter serial number that each cutter corresponds and the first load threshold value and the second load threshold value that correspond with the cutter serial number for can carry out corresponding main shaft load control to different cutters, more pertinence, and then improved main shaft load control's accuracy.
And a corresponding main shaft load monitoring function switch is arranged for each cutter number, so that a user can start or close a corresponding main shaft load monitoring function according to the condition of the cutter, and main shaft load monitoring is performed when the main shaft load monitoring function switch is started, so that the flexibility and safety of main shaft load monitoring are improved.
And by detecting whether the read tool number is consistent with the tool number corresponding to the opened main shaft load monitoring function switch, the main shaft tool is normally started only when the read tool number is consistent with the tool number corresponding to the opened main shaft load monitoring function switch, and the main shaft tool is warned and stopped when the tool number is changed, so that the safety of operation is improved. By confirming that the main shaft is in a normal working state, the accuracy of main shaft load monitoring is improved.
