Detailed Description
In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Example 1
In accordance with an embodiment of the present invention, there is provided an embodiment of a method for testing a tool magazine, it being noted that the steps illustrated in the flowchart of the drawings may be performed in a computer system such as a set of computer executable instructions, and that while a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than presented herein.
Fig. 1 is a testing method of a tool magazine according to an embodiment of the present invention, as shown in fig. 1, the method includes the following steps:
step S101, before the tool magazine is assembled to the numerical control machine, the tool magazine is controlled to simulate actual action operation in the numerical control machine;
step S102, obtaining operation parameters generated in the operation process of the tool magazine;
step S103, judging whether the tool magazine has faults or not according to the operation parameters, wherein the faults comprise: mechanical failure and/or control parameter anomalies.
The tool magazine can be selected from a chain tool magazine, an umbrella-shaped tool magazine, a disc-type tool magazine and the like for a numerical control machine tool. The mechanical parts of the tool magazine comprise a proximity switch, an inductive switch, a cutter head controlled by a servo motor, the servo motor, a transverse moving structure, a guide rail and the like.
In step S101, the tool magazine is controlled to simulate actual operation in the numerical control machine tool, and the tool magazine can be detected by the electrical control platform. Aiming at the normal ideal action of the tool magazine, the tool magazine detection electric control platform can make the tool magazine simulate the normal action on the numerical control machine tool on the tool magazine detection electric control platform by designing a control program. Optionally, the tool magazine detection electrical control platform includes a PLC Controller (Programmable Logic Controller, abbreviation of Programmable Logic Controller), an upper computer having a touch screen, and a switching power supply for supplying power.
The operation parameters in step S102 include, but are not limited to, operation sounds (e.g., tool changing sounds, motor operation sounds, etc.) of the tool magazine during operation on the tool magazine detection electrical control platform, tool changing speed, motor jitter conditions, positions of tool magazine components after tool changing actions, resonance parameters, and the like. Optionally, the operation parameters may be obtained manually, or the corresponding sensor and the testing instrument may be set to automatically obtain the operation parameters, for example, the operation sound may be obtained by the inspector sensing the volume through hearing, or may be obtained by the decibel testing instrument.
The mechanical fault in step S103 includes, but is not limited to, a mechanical fault of a speed reducer mechanically and electrically matched with the cutter head, a fault of a guide rail or a motor of a traverse structure, a fault of the cutter head controlled by a servo motor, a loosening of a proximity switch or an inductive switch or a deviation of an inductive position, a mechanical resonance of the tool magazine, and the like. The control parameter anomalies include, but are not limited to, control parameters of the tool magazine servo drive, PID control parameters for motor control, and the like.
Since different operation parameters have corresponding relations with the fault types of the tool magazine, step S103 can determine whether the tool magazine has a fault according to the various operation parameters acquired in step S102. For example, if the operation sound or the tool changing sound is larger than the sound of normal operation when the tool magazine is acquired to operate on the tool magazine detection electrical control platform, it may be determined that the tool magazine has a mechanical fault, for example, a speed reducer of the tool magazine has a mechanical fault.
It should be noted that the mechanical fault and the control parameter abnormality may exist separately or simultaneously, that is, the operation parameter of the tool magazine may point to a plurality of coexisting fault types at the same time. For example, when the sound of the motor of the tool magazine is abnormal, a mechanical failure may occur in the speed reducer, or the PID parameter setting of the servo driver controlling the motor may be unreasonable, and both may exist at the same time.
Through the steps, the tool magazine serving as a part of the numerical control machine tool is subjected to electrical control inspection in actual action by simulating the actual working condition of the numerical control machine tool, incoming material inspection before tool magazine assembly is realized, defects of the tool magazine can be found in advance, incoming material quality guarantee is provided for workshop assembly, and the problem that in the prior art, the tool magazine is required to be disassembled for repair due to faults found after assembly is solved.
Optionally, before assembling the tool magazine to the numerically controlled machine tool, controlling the tool magazine to simulate an actual motion operation in the numerically controlled machine tool, including: receiving at least one action control signal, wherein the action control signal is used for instructing the tool magazine to execute a specified action; and controlling the tool magazine to simulate actual action operation in the numerical control machine tool according to the action control signal.
The motion control signal is used for controlling the tool magazine to perform a normal motion on the numerical control machine tool, for example, the motion control signal can instruct the tool magazine to perform a tool changing motion. The action control signal can be sent by the manual control of an inspector, the inspector can select to manually control the tool magazine to execute any action through the upper computer of the tool magazine detection electric control platform (for example, the inspector sends a tool changing instruction to control the tool magazine to change the tool) and can also control the tool magazine to automatically execute through the designed automatic control program through the tool magazine detection electric control platform. The action control signal can instruct the tool magazine to execute a single action or can control the tool magazine to execute a plurality of actions. The action control signal can comprise all actions of the tool magazine in actual operation, so that the tool magazine can simulate all the actual actions possibly occurring in the numerical control machine tool, the comprehensive inspection of the tool magazine is realized, and the condition of missing inspection is avoided.
Optionally, before assembling the tool magazine to the numerically controlled machine tool, the step of controlling the tool magazine to simulate the actual motion operation in the numerically controlled machine tool further comprises: after the tool magazine simulates actual actions in the numerical control machine tool to operate according to the action control signals, if the tool magazine is determined to have no fault, receiving task control signals, wherein the task control signals are used for indicating the tool magazine to execute a plurality of continuous actions within preset time; and controlling the tool magazine to simulate the actual action operation in the numerical control machine tool according to the task control signal.
The task control signal can be automatically executed by controlling the tool magazine detection electric control platform through a set software program. Although no fault occurs after the tool magazine simulates the actual action operation in the numerical control machine tool according to the action control signal, the action control signal is only a limited certain specified action, and the result of the fault-free operation may have a certain contingency, so that a plurality of continuous actions need to be executed within a certain time to judge the repeatability of the fault-free operation result of the tool magazine, namely the reliability and the durability of the simulation operation of the tool magazine on the tool magazine detection electric control platform are obtained, after a plurality of groups of action task tests are repeated, the operation of the tool magazine still has no fault, and the tool magazine can pass the tests and is delivered to the numerical control machine tool for installation. The preset time can be set according to factors such as the configuration of the tool magazine components, and different preset times can be set for tool magazines with different types of components, which is not limited herein. For example, a tool magazine with more magazine components typically requires a longer predetermined amount of time to ensure that each set of magazine components can be adequately tested.
Optionally, the obtaining of the operation parameters generated by the tool magazine in the operation process includes: acquiring sound information of the tool magazine in the operation process, wherein the sound information at least comprises volume information; judging whether the tool magazine has faults according to the operation parameters comprises the following steps: and if the volume information of the tool magazine in the operation process is larger than the preset volume, determining that the speed reducer of the tool magazine fails.
The sound information of the tool magazine in the operation process includes, but is not limited to, the sound of the standby operation of the servo motor and the tool changing sound. The preset volume is a volume threshold value when the tool magazine works normally, and when the preset volume exceeds the volume threshold value, the fact that the speed reducer which is mechanically and electrically matched with the cutter head breaks down can be judged. For example, if a speed reducer of the tool magazine has a fault, the noise decibel of the tool magazine in operation is 4 to 5 times greater than the volume in normal operation, the tool changing sound of the tool magazine during tool changing operation can be as high as about 80 decibels, and an inspector can judge that the speed reducer has a mechanical fault according to the obviously increased volume or the decibel of the noise volume of the tool magazine in operation detected by a decibel measuring instrument.
Since the operating sound volumes of the motors or reducers of different models are different, the specific value of the preset volume is not limited herein.
In addition, sound information of the tool magazine in the operation process is obtained, and the sound also comprises abnormal sound in the operation process. For example, if the motor controlling the traverse structure of the tool magazine makes an abnormal sound, it may be determined that there is a mechanical failure in the motor or the servo driver controlling the traverse structure of the tool magazine.
Optionally, the obtaining of the operation parameters generated by the tool magazine in the operation process includes: acquiring the running speed of a tool magazine in the tool changing process; judging whether the tool magazine has faults or not according to the operation parameters comprises the following steps: and if the response speed of the tool magazine in the operation process is not in a first preset range, determining that the control parameter of a servo driver of the tool magazine is abnormal.
The first preset range is a normal response speed range of tool magazine tool changing action, the response speed of the tool magazine tool changing action is not in the first preset range, and the response speed is greater than the first preset range (namely the tool magazine tool changing speed is too high) and is less than the first preset range (namely the tool magazine tool changing speed is too low, and a tool magazine cutter head does not conduct the tool changing action). The servo driver of the tool magazine is used for providing a driving control signal for the servo motor for controlling the cutter head of the tool magazine, and if the tool changing speed of the tool magazine is too slow or too fast, the problem of the parameter of the servo driver of the control motor can be judged, so that the operation speed of the servo motor for controlling the cutter head is too fast or too slow.
For example, if the speed of the tool magazine tool changing operation is too slow, which indicates that the servo motor is in heavy rotation or overloaded, it may be determined that the inertia ratio of the control parameters of the servo driver of the tool magazine is set to be larger, and it is necessary to adjust the inertia ratio of the servo driver of the tool magazine to be smaller, or optimize the PID control parameters of the servo driver, or optimize the filter parameters until the servo motor operates normally. Meanwhile, the tool changing software program of the tool magazine can be optimized, the tool changing speed is increased, the single tool changing time of the tool magazine is shortened, the stable operation of the tool changing action of the tool magazine is guaranteed, and the stable and quick balance of the tool magazine is realized.
Optionally, the obtaining of the operation parameters generated by the tool magazine in the operation process includes: acquiring the position of the tool magazine after the tool changing action is executed; judging whether the tool magazine has faults according to the operation parameters comprises the following steps: and determining that the tool magazine has a fault when the position of the tool magazine after the tool changing action is not the position indicated in the control signal.
The position after the tool changing action is obtained by arranging a displacement sensor. For example, a displacement sensor is arranged on a guide rail structure of the tool magazine transverse moving structure, and the position change of the tool magazine assembly is obtained through the displacement distance of the tool magazine transverse moving structure on the guide rail. The position after the tool changing action can also be manually obtained by a detection person to judge whether the tool magazine has faults or not, for example, the tool magazine assembly cannot be retracted after the tool is discharged, or the position of the tool magazine assembly far away from the workpiece to be processed can be identified in a manual mode.
The position of the magazine after performing the tool changing action is not the position indicated in the control signal, including but not limited to the position where the magazine assembly in the magazine is not switched to the correct position (including being unable to retract after the tool is removed, and the magazine assembly being removed further from the position of the workpiece to be machined or not moving to the machining zone), or not reaching the degree of rotation (e.g., indicating that the rotary-type tool is stopped after rotating 180 °, but the tool is not rotated 180 °).
The following description will be made, with reference to an alternative embodiment, of a method for determining that a tool magazine has a fault according to a position of the tool magazine after a tool changing operation is performed: the action control signal indicates that the knife is switched from No. 1 to No. 2, but the No. 1 knife cannot be retracted to the appointed position or the No. 2 knife cannot reach the appointed working position due to the fact that a mechanical fault exists in a guide rail or a servo motor of a tool magazine transverse moving structure, or a proximity switch or an induction switch is loosened or the induction position has deviation. Therefore, according to the position information of the tool magazine assembly after tool changing, one or more of the guide rail, the servo motor, the proximity switch or the induction switch of the transverse moving structure in the tool magazine can be judged to have faults, and inspectors can check the faults one by one.
Optionally, the obtaining of the operation parameters generated by the tool magazine in the operation process includes: acquiring a resonance parameter for indicating whether the tool magazine generates resonance or not, wherein the resonance parameter at least comprises a resonance frequency; judging whether the tool magazine has faults according to the operation parameters comprises the following steps: if the tool magazine generates resonance, the absence of resonance frequency in the filter parameters is determined.
In the process that the tool magazine simulates actual operation on the tool magazine detection electrical control platform, if a certain mechanical position of the tool magazine shakes abnormally, it can be judged that the mechanical position of the tool magazine generates mechanical resonance, the generation reason of the mechanical resonance is unreasonable because the filter parameter of a servo driver of the tool magazine is set, and particularly the filter parameter lacks resonance frequency, so when the component of the tool magazine needs to move to the mechanical position, the debugging software of the servo driver automatically acquires the resonance frequency at the resonance point, and accordingly filter parameters are optimized.
In addition, the servo motor is slightly jittered in a static state, and it is likely that the PID parameters of the servo driver for controlling the motor are not well adjusted, and the parameters of P/I/D need to be adjusted until the servo motor is not jittered.
By the control method, the electrical control inspection of the part tool magazine of the numerical control machine tool before assembly is realized, the defects of the tool magazine can be found in advance, the technical problem that the incoming material of the tool magazine is difficult to inspect and the problem that the tool magazine in the prior art needs to be disassembled for repair because the tool magazine finds faults after assembly are solved, whether the software program for tool changing of the numerical control machine tool has defects or not can be verified, and incoming material quality guarantee is provided for workshop assembly. Under the condition that the tool magazine is verified to be free of abnormity, the tool magazine can be transported to a workshop for assembly, and if the checked tool magazine has faults, parts can be arranged to be overhauled and replaced in time, so that the reliability of the tool magazine on a numerical control machine tool is guaranteed. In addition, aiming at the new tool magazine, the developed tool magazine is used for detecting the optimal control parameters which can be obtained by debugging the electrical control platform, and the optimal control parameters are directly provided for machine tool debugging personnel to adopt, so that the quality of the tool magazine is ensured, the debugging period of the electrical debugging personnel of the numerical control machine is saved, and the assembling completion period of the numerical control machine is obviously accelerated.
