Deburring adding method embodiment based on current control：
Deburring adding method provided by the utility model based on current control, it uses the deburrings of above-described embodiment
System carries out deburring to workpiece, and deburring adding method is introduced below in conjunction with Fig. 3 and Fig. 4.
First, step S1 is executed, i.e., default step is written operation program to ontology, and pre-sets baseline threshold.Specifically
Ground can execute step S1 by client 9, for example, when the client 9 is touch display, user can be by this
Touch display carries out the relative parameters setting of operation program, such as setting, the 22 total feed amount of deburring tool of baseline threshold
Setting, the 22 single amount of feeding of deburring tool setting etc..When the client 9 is PC terminals, user can pass through the PC
Terminal will run the ontology 61 of the writing controller 6 of program, and can be run by the PC terminal-pairs program into edlin, repair
Change, certainly, PC terminals can also carry out the relative parameters setting of operation program.
After completing step S1, ontology 61 can run above-mentioned operation program, start to execute step S2, that is, execute step,
Propulsive mechanism is moved according to the deburring tool of operation driven by program burring mechanism to workpiece.At this point, ontology 61 is according to operation
The control instruction of program controls propulsive mechanism 3, makes propulsive mechanism 3 that burring mechanism 2 be driven to move, so that unhairing
The deburring tool 22 for piercing mechanism 2 is moved to workpiece 10, and carries out deburring processing to workpiece 10.For example, 3 basis of propulsive mechanism
The deburring tool 22 for running the instruction control burring mechanism 2 of program carries out first time feeding.In another example working as deburring tool
22 complete for the first time feed after, propulsive mechanism 3 according to operation program instruction control burring mechanism 2 deburring tool 22 into
Second of feeding of row.
While executing step S2, step S3, i.e. sampling step can be executed, current detecting unit is to first motor
Present load current is detected, and current transducer obtains the present load current of current detecting unit detection, and will currently bear
It carries after electric current is converted into standard analog signal and is sent to analog-digital converter, standard analog signal is converted into number by analog-digital converter
Current signal.
Since first motor 21 is for driving deburring tool 22 to rotate so that when deburring tool 22 and workpiece 10 connect
When touching, the frictional force between deburring tool 22 and workpiece 10 can influence the load current of first motor 21, and work as deburring
When frictional force between tool 22 and workpiece 10 is bigger, the load current of first motor 21 is also bigger.And current detecting unit 4 is logical
It crosses and is connect with the phase line of first motor 21, the present load current for obtaining first motor 21, and by the present load of acquisition
Electric current is sent to current transducer 5, makes current transducer 5 that the present load current is converted into standard analog signal, subsequently
The standard analog signal is sent to the analog-digital converter 62 of controller 6.Analog-digital converter 62 is obtaining the standard analog signal
Afterwards, which is converted into digital current signal and is sent to the ontology 61 of controller 6.
Certainly, when propulsive mechanism 3 drives burring mechanism 2 to be moved to workpiece 10, the first motor 21 of burring mechanism 2
With one section of unloaded phase, therefore step S3 can also start that burring mechanism 2 is driven to be moved to unhairing to workpiece 10 in propulsive mechanism 3
Just start to execute in this period before the deburring tool 22 of thorn mechanism 2 is contacted with workpiece 10.
After the completion of step S3, step S4 is executed, i.e. set-up procedure, after ontology acquisition digital current signal, to benchmark threshold
Value and digital current signal are compared, and the amount of feeding of pushing mechanism is adjusted according to comparison result.That is the ontology 61 of controller 6
After obtaining the digital current signal that analog-digital converter 62 is sent, according to the instruction of operation program to digital current signal and benchmark
The value of threshold value is compared, and is controlled between the deburring tool 22 of burring mechanism 2 and workpiece 10 according to the result of the comparison
Relative position, and then the frictional force between deburring tool 22 and workpiece 10 is adjusted so that 22 energy of deburring tool
It is enough in a preferably Working position, then ensures the machining accuracy and processing quality of workpiece 10.
Specifically, with reference to Fig. 4, when executing set-up procedure, specific execution content is as follows：
First, step S41 is executed, judges whether digital current signal is more than baseline threshold.If so, S42 is thened follow the steps,
Ontology control control propulsive mechanism drives burring mechanism to be moved towards the direction far from workpiece.For example, the size when workpiece 10 is big
In advance simulation or the size of pre-set workpiece, at this moment, when propulsive mechanism 3 to run the order-driven deburring machine of program
Structure 2 is moved to workpiece 10, since the size of workpiece 10 is more than the size of simulation or pre-set workpiece in advance so that deburring
The deburring tool 22 of mechanism 2 is more than simulation or the pre-set standard amount of feeding in advance to the practical amount of feeding of workpiece 10, this
When, the frictional force between deburring tool 22 and workpiece 10 can be bigger than normal, and the load current of first motor 21 is caused to be more than normal add
The load current of work, and the machining accuracy and processing quality of workpiece 10 are impacted, it is unfavorable for carrying out deburring to workpiece 10
Processing.And when the present load current of first motor 21 is sent to controller by current detecting unit 4 by current transducer 5
After 6 analog-digital converter 62, which is processed into digital current signal and is sent to ontology by analog-digital converter 62
61 so that ontology 61 is compared the digital current signal with preset baseline threshold, at this point, the value of the digital current signal
The value of baseline threshold can be more than, and then ontology 1 can control propulsive mechanism 3 according to operation program, and propulsive mechanism 3 is made to drive deburring
Mechanism 2 is moved towards the direction far from workpiece 10, to reduce the frictional force between deburrer 22 and workpiece 10, ensures workpiece 10
Machining accuracy, processing quality and the consistency of processing.
What needs to be explained here is that the value perseverance of corresponding digital current signal is less than benchmark threshold when first motor 21 is unloaded
The value of value.In addition, the value of the baseline threshold can be a determining value, can also be a value range, because each
Measured value can have certain measurement error, therefore be not specifically limited here to baseline threshold.
When judging that digital current signal is less than or equal to baseline threshold, step S43 is executed, judges that digital current signal is
It is no to be equal to baseline threshold.If so, thening follow the steps S44, ontology controls the current location that propulsive mechanism keeps burring mechanism.Cause
If the value of digital current signal is equal to the value of baseline threshold, that is, to illustrate that current deburring tool 22 is in one preferably
Working position, and the frictional force between deburring tool 22 and workpiece 10 is moderate, therefore ontology 61 can be pushed away according to operation program control
The current location of burring mechanism 2 is kept into mechanism 3.
If step S43 judges that digital current signal is not equal to baseline threshold, illustrate that digital current signal is less than benchmark threshold
Value, at this point, executing step S45, ontology controls propulsive mechanism and burring mechanism is driven to be moved towards close to the direction of workpiece.For example,
When workpiece 10 size be less than in advance simulation or pre-set workpiece size, at this moment, when propulsive mechanism 3 is to run program
Order-driven burring mechanism 2 is moved to workpiece 10, since the size of workpiece 10 is less than simulation or pre-set workpiece in advance
Size so that the deburring tool 22 of burring mechanism 2 is less than simulation in advance to the practical amount of feeding of workpiece 10 or sets in advance
The standard amount of feeding set, at this point, the frictional force between deburring tool 22 and workpiece 10 can be less than normal, i.e. deburring tool 22 and work
The contact surface of part 10 is too small, and the Working position of deburring tool 22 is excessively high, causes the load current of first motor 21 to be less than normal
The load current of processing can impact the machining accuracy and processing quality of workpiece 10, be unfavorable for carrying out unhairing to workpiece 10
Thorn processing.And when the present load current of first motor 21 is sent to control by current detecting unit 4 by current transducer 5
After the analog-digital converter 62 of device 6, which is processed into digital current signal and is sent to this by analog-digital converter 62
Body 61 so that ontology 61 is compared the digital current signal with preset baseline threshold, at this point, the digital current signal
Value can be less than the value of baseline threshold, and then ontology 1 can control propulsive mechanism 3 according to operation program, and propulsive mechanism 3 is made to drive unhairing
It pierces mechanism 2 to move towards close to the direction of workpiece 10, to increase the frictional force between deburrer 22 and workpiece 10 so that unhairing
There is frictional force appropriate between thorn tool 22 and workpiece 10, to ensure the one of the machining accuracy of workpiece 10, processing quality and processing
Cause property.
Certainly, the value that the value of digital current signal is less than baseline threshold also has a kind of situation, i.e., when deburring tool 22 is right
When the workpiece 10 completes deburring, the frictional force between deburring tool 22 and workpiece 10 can level off to zero, i.e., at this time
The load current of first motor 21 can level off to no-load current, at this point, ontology 61 equally can control pusher according to operation program
Structure 3 makes propulsive mechanism 3 that burring mechanism 2 be driven to be moved towards close to the direction of workpiece 10, to continue to complete the deburring in this stage
The feeding of tool 22 or continue to complete next stage deburring tool 22 feeding.
In addition, set-up procedure further includes driving burring mechanism 2 towards far from workpiece 10 when ontology 61 controls propulsive mechanism 3
When direction is moved, the driving end that ontology 61 controls counterweight cylinder 8 simultaneously is moved along the rise direction of counterweight cylinder 8；When ontology 61
Controlling propulsive mechanism 3 drives burring mechanism 2 towards when being moved close to the direction of workpiece 10, and ontology 61 controls the drive of counterweight cylinder 8
It is moved along the backhaul direction of counterweight cylinder 8 moved end.The reason of executing the step is：Due to first motor 21, deburring tool
22 equal components all have larger weight so that if propulsive mechanism 3 will with enough driving forces come drive burring mechanism 2 into
Row movement, it is necessary to which the load capacity for increasing the second motor 31, the volume so as to cause the second motor 31 can be increased, and be arranged
Counterweight cylinder 8 so that when the second motor 31 drives burring mechanism 2 close to workpiece 10, the second motor 31 of auxiliary is to deburring
Mechanism 2 is moved down；When the second motor 31 drives burring mechanism 2 far from workpiece 10, the second motor 31 of auxiliary is to deburring
Mechanism 2 is moved up, to while reducing the volume of the second motor 31, ensure that the second motor 31 disclosure satisfy that driving unhairing
Pierce the requirement that mechanism 2 moves.
After completing step S4, step S5 is executed, judges whether the total feed amount of deburrer 22 reaches the total of setting
The amount of feeding.Since the deburring of part workpiece is carried out by way of feeding stage by stage, and above-mentioned steps S3 and step
S4 is that the present load current for the first motor 21 for being directed to a certain stage sample and adjusted to the position of burring mechanism 2
Section, therefore after the operation for completing step S3 and step S4, it needs to judge whether workpiece 10 completes deburring processing, even workpiece 10
It is to carry out deburring processing by the way of feeding stage by stage, whether needs through the total feed amount that judges deburring tool 22
Workpiece through reaching setting completes the total feed amount that deburring needs, if so, terminating the deburring to workpiece 10.
No to then follow the steps S6, propulsive mechanism drives the feeding of deburring tool progress next stage.That is, when burring mechanism 2 is completed
After the deburring in a certain stage, when the deburring processing of workpiece 10 has not been completed, propulsive mechanism 3 can drive deburring machine
The deburrer 22 of structure 2 carries out the feeding of next stage, continues to complete the deburring to workpiece 10, until underturner
Until the total feed amount of tool 22 reaches the total feed amount of setting.Certainly, deburring stage of each deburring tool 22 goes
