Specify the use of the utility model below:
One, the mensuration of braking time: this kind situation has clamping the first magnetic bases clamping device of first sensor 231 to be placed near the detent of electric chain saw.Its concrete steps comprise:
S11: be fixedly mounted on electric chain saw on the sectional fixture, and press the power switch of electric chain saw, make it in running order, the saw chain setting in motion.Need to prove that the action of pressing the power switch of electric chain saw here can also can realize through first solenoid valve, 211 controls, first cylinder 221 through manually realizing.
S12: the user assigns the instruction of measuring the electric chain saw braking time from touch screen module 11 to this electric chain saw transient motion time measurement system 500; Touch screen module 11 is received the instruction back and is transferred to PLC control module 12 to this command information;
12 pairs of these command informations of S13:PLC control module carry out assigning action command to the 3rd solenoid valve 213 after the processed, and connected the 3rd cylinder 223 of the 3rd solenoid valve 213 controls is pounded the detent to electric chain saw; Instantaneous braking maneuver takes place in detent.
At this moment, it is different that near the first sensor 231 it detects reflective amount through it, and this snap action of immediate record also triggers second sensor 232 immediately.Second sensor carries out record to this time as very first time T1 immediately, and feeds back to PLC control module 12 to T1 through the second sensor control module 132.
S14: after the detent of electric chain saw moved, the motion of saw chain was slowed down gradually, on saw chain
When surpassing 10ms through time of a point of fixity, 2 adjacent sawtooth think that electric chain saw stops.At this moment, be positioned near second sensor 232 of saw chain and detect this variation, and be recorded as T2 to first sawtooth elapsed time in above-mentioned 2 sawtooth.And second sensor 232 feeds back to PLC control module 12 to this time T 2 through the second sensor control module 132.
Second sensor 232 specifically is placed on the one side of saw chain.Its location to sawtooth is to set according to the reflecting rate of serrated surface.Do like this and can eliminate the interference to final measurement such as knife, avoid error, precision measure is provided.
In the specific implementation, can also be at the another side of saw chain the position of relative second sensor 232 place a laser sensor that reflective amount is adjustable again.Through two laser sensors sawtooth is positioned, can further prevent erroneous judgement.
12 pairs of time T that feed back of S15:PLC control module 1 are calculated with T2, make T2-T1 obtain the saw chain braking time of this electric chain saw.And PLC control module 12 feeds back to touch screen module 11 after handling this braking time.The user can read the saw chain braking time of this electric chain saw from this touch screen module 11, thereby judges whether it meets safety standard.
S16: after accomplishing test, 12 pairs second solenoid valves 212 of PLC control module are assigned instruction, and connected second cylinder 222 of second solenoid valve, 212 controls promotes detent from the reverse side of the detent of electric chain saw, makes it get back to initial position.
Two, the mensuration of stand-by time: this kind situation has clamping the first magnetic bases clamping device of first sensor 231 to be placed near the power switch of electric chain saw; Its concrete steps comprise:
S21: be fixedly mounted on electric chain saw on the sectional fixture, and open the power switch of electric chain saw, make it in running order, the saw chain setting in motion.Need to prove; Here press the implementation of action of the power switch of electric chain saw: 12 pairs first solenoid valves 211 of PLC control module are assigned action command, and connected first cylinder 221 of first solenoid valve, 211 controls is pressed the power switch of the electric chain saw of its top.
In addition, because the power switch of electric chain saw has two, so first cylinder is provided with a linkage, it acts on two power switches of electric chain saw simultaneously.
S22: the user assigns the instruction of the saw chain stand-by time of measuring electric chain saw to this electric chain saw transient motion time measurement system 500 from touch screen module 11; Touch screen module 11 is received the instruction back and is transferred to PLC control module 12 to this command information;
12 pairs of these command informations of S23:PLC control module carry out assigning action command to first solenoid valve 211 after the processed; Connected first cylinder 221 of first solenoid valve, 211 controls discharges the power switch of its electric chain saw of pressing, and makes it cut off the power supply of electric chain saw.It should be noted that so first cylinder is provided with a linkage, it acts on two power switches of electric chain saw simultaneously because the power switch of electric chain saw has two.
At this moment, near the first sensor 231 it detects this snap action and takes place, and the time that this snap action of immediate record takes place as very first time T1, and feed back to PLC control module 12 to this time through first sensor control module 131.
S24: behind the passing through power switch and cut off power supply of electric chain saw, the motion of saw chain is slowed down gradually, when 2 adjacent on saw chain sawtooth surpass 10ms through time of a point of fixity, thinks that electric chain saw stops.At this moment, be positioned near second sensor 232 of saw chain and detect this variation, and be recorded as T2 to first sawtooth elapsed time in above-mentioned 2 sawtooth.And second sensor 232 feeds back to PLC control module 12 to this time T 2 through the second sensor control module 132.
12 pairs of time T that feed back of S25:PLC control module 1 are calculated with T2, make T2-T1 obtain the saw chain stand-by time of this electric chain saw.And PLC control module 12 feeds back to touch screen module 11 after handling this stand-by time.The user can read the saw chain stand-by time of this electric chain saw from this touch screen module 11, thereby judges whether it meets safety standard.
Need to prove that in the present embodiment, first sensor 231, second sensor 232 are the laser sensor that reflective amount can be regulated; First cylinder 221, second cylinder 222, the 3rd cylinder 223 are accurate cylinder.Present embodiment is to control part with accurate cylinder as mode of motion, adopts reflective amount scalable laser sensor, under the noncontact mode, realizes the run duration collection to the different moving object of surperficial reflecting rate.
The utility model preferred embodiment just is used for helping to set forth the utility model.Preferred embodiment does not have all details of detailed descriptionthe, does not limit this utility model yet and is merely described embodiment.Obviously, according to the content of this instructions, can do a lot of modifications and variation.These embodiment are chosen and specifically described to this instructions, is principle and practical application in order to explain the utility model better, thereby person skilled can be utilized the utility model well under making.The utility model only receives the restriction of claims and four corner and equivalent.More than the disclosed several specific embodiments that are merely the application, but the application is not limited thereto, any those skilled in the art can think variation, all should drop in the application's the protection domain.
