The method for detecting the internal broken tool of the tool magazine, provided by the embodiment of the invention, is applied to electronic equipment.

S1: and acquiring the detection time of the servo motor to the cutter to be detected as target time.

Specifically, the embodiment of the application is a tool magazine internal broken tool detection method based on a numerical control system. The numerical control system is a control system which integrates all numerical control system elements (a numerical controller, a programmable controller and a human-computer operation interface) into a whole in an operation panel installation mode. The target time refers to the time from the time when the servo motor starts at the origin of the shifting rod to the time when the servo motor touches the tool nose of the tool to be detected and the torque of the servo motor reaches a preset value.

In one embodiment, the pre-test job needs to be ready before the start of the break test. The method comprises the following specific steps: the servo motor is arranged in the tool magazine, the tool sleeve of the cutter head is corrected, the shifting rod needs to be aligned with the center of the tool sleeve and cannot have large deviation, after the mechanical position is calibrated, the speed of the servo motor of the cutter breaking instrument and a preset precision value are set and input into a detection system, finally, the shifting piece of the cutter breaking instrument is placed below the longest cutter, and the original point of the shifting piece is set. At this time, the cutter breaking instrument is completely installed, and then the test is started.

Referring to fig. 2, fig. 2 shows an embodiment before S1, which is described in detail as follows:

s01: and acquiring undetected tools of multiple types and sample tools corresponding to the tools to be detected, and taking the sample tools as target teaching tools.

S02: and based on the target teaching tool, acquiring a preset precision value of the undetected tool.

S03: and acquiring the detection time of the servo motor for teaching the target tool to obtain the teaching time.

S04: and storing the preset precision value and the teaching time in a preset database.

In the embodiment of the application, each type of cutter has the corresponding original length, so that different precision values are required for detecting the broken cutters of different types of cutters. And each type of tool has a different detection time. Therefore, the embodiment of the application obtains the undetected tools of multiple types and the sample tools corresponding to the tools to be detected, and takes the sample tools as target teaching tools. Then, according to the target teaching tool, acquiring a preset precision value of an undetected tool to obtain a preset precision value of each type of tool, acquiring detection time of the servo motor on the target teaching tool to obtain teaching time, and finally storing the teaching time in a preset database; furthermore, different servo motor speeds can be set according to different cutter types, and the servo motor speeds are correspondingly stored in a preset database, so that corresponding precision values can be directly called when subsequent cutter breakage detection is required, and the efficiency of cutter breakage detection is improved. The sample tool is a tool having an initial length immediately after shipment.

Referring to fig. 3, fig. 3 shows an embodiment of step S03, which is described in detail as follows:

s031: and acquiring a first teaching instruction, wherein the first teaching instruction comprises a teaching tool number.

S032: and executing the first teaching instruction, acquiring a target teaching tool corresponding to the teaching tool number, driving the servo motor to rotate through the servo driver based on the first teaching instruction, and acquiring the current time point of the servo motor at the original point of the deflector rod as a first teaching time point.

S033: when the servo motor touches the tool nose of the teaching tool and the torque of the servo motor reaches a set value, first teaching feedback information is obtained, and a second teaching time point is obtained based on the first teaching feedback information.

S034: and generating the teaching time based on the difference value between the second teaching time point and the first teaching time point.

The teaching tool is a tool having an initial length immediately after shipment. The teaching time refers to the time taken by the servo motor from the moment when the servo motor starts to be at the original point of the deflector rod and touches the tool nose of the teaching tool and the moment of the servo motor reaches a preset value.

The first teaching command is a command for detecting a teaching tool. For example, the first teaching command is M600Tx (x represents a teaching tool number).

Specifically, since the first teaching command includes the teaching tool number, when the first teaching command is executed, the corresponding teaching tool can be detected. Servo driver drive servo motor rotates for it is rotatory to drive servo motor's driving lever, and when servo motor's driving lever touched the knife tip of teaching cutter, servo motor's electric current can change this moment, can kick-back rapidly by the motor after reaching certain numerical value as the arrival electric current. Therefore, whether the tool nose is touched and the torque of the servo motor reaches a preset value is determined through the current of the servo motor, the current of the servo motor is obtained and used as first teaching feedback information, and then the current time is obtained and used as a first teaching time point. And subtracting the first teaching time point from the second teaching time point to obtain the teaching time.

The set value is set according to actual conditions, and is not limited here. The original point of the deflector rod set when the teaching tool and the tool to be detected are at the same position.

Referring to fig. 4, fig. 4 shows an embodiment before step S1, which is described in detail as follows:

S1A: and acquiring the type of the tool corresponding to the tool to be detected.

S1B: and acquiring a preset precision value and a servo motor speed corresponding to the type of the tool from a preset database.

S1C: based on the servo motor speed, a preset accuracy value is converted into a preset time accuracy value.

In particular, since different types of tools may exist inside the tool magazine, the length and the width of each type of tool are different, thereby causing different detection time lengths. Therefore, in the embodiment of the application, the type of the tool corresponding to the tool to be detected is obtained first, and since the preset precision value and the servo motor speed are already set for different types of tools and stored in the preset database before each type of tool is detected, the preset precision value and the servo motor speed corresponding to the type of the tool are obtained from the preset database, and then the preset precision value is converted into the preset time precision value based on the servo motor speed.

Referring to fig. 5, fig. 5 is a schematic diagram illustrating an accuracy value setting according to an embodiment of the invention.

In fig. 5, the left side is a sketch, and if the length of the paddle is within an allowable accuracy range when the blade edge is touched, it is assumed that the right side is a drawing, Δ s = s1-s2= vt1-vt2= v (t 1-t 2), that is, a required accuracy value Δ s = a difference value obtained by multiplying a servo motor speed value v by a detection value t1 and a teaching value t 2. Since the precision value has been set and the servomotor speed value is also set, the preset precision value can be converted into a preset time precision value, = Δ t = =Δs/v.

Referring to fig. 6, fig. 6 shows an embodiment of step S1, which is described in detail as follows:

s11: and acquiring a second teaching instruction, wherein the second teaching instruction comprises a tool number.

S12: and executing a second teaching instruction, acquiring the to-be-detected cutter corresponding to the cutter number, driving the servo motor to rotate through the servo driver, and acquiring the current time point of the servo motor at the original point of the deflector rod as a first target time point.

S13: when the servo motor touches the tool nose of the tool to be detected and the torque of the servo motor reaches a set value, first detection feedback information is obtained, and a second target time point is obtained based on the first detection feedback information.

S14: and generating the target time based on the difference value between the second target time point and the first target time point.

Specifically, the second teaching instruction is an instruction that needs to detect the tool to be detected. For example, the first teaching command is M600Ty (y represents a tool number).

Specifically, since the second teaching instruction includes the tool number, when the second teaching instruction is executed, the corresponding tool to be detected can be detected. The servo driver drives the servo motor to rotate, and the current time point of the servo motor at the original point of the deflector rod is obtained and used as a first target time point. Because servo driver drive servo motor rotates for the driving lever that drives servo motor is rotatory, when servo motor's driving lever touched the knife tip of waiting to detect the cutter, servo motor's electric current can change this moment, and the motor can kick-back rapidly after reaching electric current and reaching certain numerical value. Therefore, whether the tool nose is touched or not is determined through the current of the servo motor, if the tool nose is touched and the torque of the servo motor reaches a preset value, the current of the servo motor is obtained to serve as first detection feedback information, and then the current time is obtained to serve as two target time points. And performing subtraction processing on the two target time points and the first target time point to obtain target time.

It should be noted that, in the detection process of the teaching tool and the tool to be detected, the speeds of the servo motors are the same.

S2: and acquiring the teaching time corresponding to the tool to be detected from a preset database, and acquiring the difference time period between the target time and the teaching time.

Specifically, the difference time period is obtained by subtracting the teaching time from the target time.

Referring to fig. 7, fig. 7 shows an embodiment after step S2, which is described in detail as follows:

S2A: the difference time period is compared to a preset threshold.

The preset threshold comprises a first threshold, a second threshold and a third threshold.

S2B: and when the difference time period is within the first threshold value, judging that the cutter to be detected is in first-level loss.

S2C: and when the difference time period is within a second threshold value, judging that the tool to be detected is in secondary loss.

S2D: and when the difference time period is within a third threshold value, judging that the tool to be detected has three-level loss.

Specifically, in the detection process of the teaching tool and the tool to be detected, the speeds of the servo motors are the same, so that the length difference between the teaching tool and the tool to be detected can be obtained by multiplying the difference time period by the speed of the servo motor. Therefore, the wear degree of the tool to be detected is judged according to the difference time period. In the embodiment of the application, the preset threshold values comprise a first threshold value, a second threshold value and a third threshold value through presetting the threshold values in advance, and each threshold value corresponds to the loss degree of the cutter. Therefore, the difference time period is compared with a preset threshold value, and when the difference time period is within a first threshold value, the cutter to be detected is judged to be in first-level loss; when the difference time period is within a second threshold value, judging that the cutter to be detected is in secondary loss; and when the difference time period is within a third threshold value, judging that the tool to be detected has three-level loss. The primary loss, the secondary loss and the tertiary loss respectively represent the loss degree of the cutter, and the loss severity is the primary loss, the secondary loss and the tertiary loss from light to heavy. Further, not only the three thresholds and the three level losses may be defined, but also different thresholds and level losses may be set according to actual situations.

The preset threshold, the first threshold, the second threshold, and the third threshold are set according to actual conditions, and are not limited herein. The third threshold is greater than the first threshold and the second threshold, and the second threshold is greater than the first threshold.

S3: and if the difference time period is greater than the preset time precision value, judging that the cutter to be detected is broken, and sending warning information.

Specifically, if the degree of wear of the tool is large, it can be determined that the tool has broken. According to the embodiment of the application, the precision value is set according to different cutter types and can be converted into the corresponding preset time precision value, so that the difference time period is compared with the preset time precision value, if the difference time period is larger than the preset time precision value, the cutter to be detected is judged to be broken, and warning information is sent; if the difference time period is smaller than the preset time precision value, the cutter to be detected is judged not to be broken, and warning information does not need to be sent out. Wherein, the information of warning can be warned through the alarm lamp, if judge that the cutter has taken place the fracture, then the alarm lamp takes place the scintillation, otherwise, the alarm lamp does not take place the scintillation.

In the embodiment, the detection time of the servo motor for the cutter to be detected is obtained and used as the target time; acquiring teaching time corresponding to a tool to be detected from a preset database, and acquiring a difference time period between target time and the teaching time; and if the difference time period is greater than the preset time precision value, judging that the cutter to be detected is broken, and sending warning information. According to the embodiment of the invention, the detection time and the teaching time of the tool to be detected are obtained, the difference time period of the detection time of the tool to be detected and the teaching time is obtained, and the difference time period is compared with the preset time precision value, so that whether the tool is broken or not is judged, the direct measurement of the length of the tool is avoided, and the detection efficiency of tool breakage in a tool magazine is improved.
