Shell 11 is cylindric.Shell 11 comprises roof 111 and a sidewall 113.Roof 111 is provided with a through hole 1112.Sidewall 113 is hollow cylindrical.Sidewall 113 offers a spacing hole 1132.Limited block 15 can stretch into spacing hole 1132.Roof 111 is positioned at sidewall 113 top, sidewall 113 bottom end opening.
Inner sleeve 13 can stretch in this shell 11, and inner sleeve 13 comprises sleeve 131 and a threaded portion 133.Sleeve 131 is hollow cylindrical.Sleeve 131 offers a stopper slot 1311, stopper slot 1311 extends along the axis being parallel to this sleeve.Limited block 15 can move in stopper slot 1311.Threaded portion 133 is provided with external screw thread and offers installing hole 1332 (see Fig. 4), and installing hole 1332 is provided with internal thread.
Contact block 20 comprises a contact site 21 and and stretches into portion 23.Contact site 21 is discoid, and the area of contact site 21 is greater than the area of the through hole 1112 of shell 11, stretches into portion 23 for cylindric, stretches into portion 23 and can stretch into through hole 1112.Contact block 20 can be made of metal.
Elastic component 30 is a spring.Elastic component 30 can be placed in this housing 10, and its two ends elasticity conflict inner sleeve 13 and shell 11.
Proximity switch 50 comprises fixed part 53, induction part 51 and a connecting line 55.Induction part 51 and connecting line 55 are positioned at the two ends of fixed part 53.Fixed part 53 is cylindric, and it is provided with external screw thread.
Controller 70 can be a computer, server or terminal device.In the present embodiment, controller 70 is a notebook computer.Proximity switch 50 carries out data transmission by connecting line 55 connection control device 70.In other embodiments, proximity switch 50 is connected with controller 70 by wireless mode.
In the present embodiment, lock nut 60 is hex nut and can be set on proximity switch 50.
Refer to Fig. 2 to Fig. 4, during assembling, be positioned on horizontal plane by base 80, be positioned over by contact block 20 on shell 11 and make the portion that stretches into 23 stretch in through hole 1112, contact site 21 is conflicted the roof 111 of shell 11.The threaded portion 133 of inner sleeve 13 is locked in the fixing hole 811 of base 80.Lock nut 60 is positioned over the bottom of threaded portion 133, in the installing hole 1332 that this proximity switch 50 is locked in threaded portion 133 in the installing space 85 of base 80 and this lock nut 60.Be positioned over by elastic component 30 in inner sleeve 13, the bottom of this elastic component 30 is sheathed on proximity switch 50.Shell 11 is sheathed in inner sleeve 13 together with contact block 20, the upper end of elastic component 30 is made to be sheathed on the portion that stretches into 23 of contact block 20 and elasticity contacts at shell 11, placed by the stopper slot 1311 of the spacing hole 1132 of shell 11 towards inner sleeve 13, limited block 15 to be installed in spacing hole 1132 and to stretch in stopper slot 1131.
Please continue to refer to Fig. 5 and Fig. 6, during use, one cutter 200 to be measured moves down a setpoint distance and compresses contact block 20, contact block 20 promotes the relative inner sleeve 13 of shell 11 and moves down, the portion that stretches into 23 of contact block 20 is gradually near proximity switch 50, and proximity switch 50 can detect the distance of the portion of stretching into 23 end and proximity switch 50.When cutter 200 to be measured is intact cutter, proximity switch 50 detects that proximity switch 50 is to stretching into the distance in portion 23 in the normal range (NR) of setting, and 51 of proximity switch 50 sends by signal to controller 70, and cutter 200 to be measured detects and passes through.When cutter to be measured 200 is for damaging cutter, proximity switch 50 detects that proximity switch 50 does not reach the normal range (NR) of setting to the distance stretching into portion 23, proximity switch 50 send not by signal to controller 70, controller 70 is reported to the police.Contact block 20 resets because elastic component 30 acts on while cutter 200 to be measured lifts, and the displacement that stopper slot 1311 limits limited block 15 makes shell 11 and contact block 20 get back to initial position.
In the present embodiment, when proximity switch is triggered there is not actual contact in contact block with proximity switch.Proximity switch can adopt inductance principle, can trigger judge whether cutter to be measured damages when the portion that the stretches into 2-3 millimeter of distance contact block, thus avoid directly with cutter hard contact to be measured and damage is brought to cutter to be measured when detecting.Proximity switch to area with apart from the quick ﹐ of sense adopt contact block and not the object of direct-detection cutter be make induction area keep constant, though if directly make cutter and proximity switch close to also triggering proximity switch, but it is tens of cutters to be measured different for diameter because generally having in lathe, it is different that proximity switch triggers distance when responding to the different target of diameter cutter to be measured, cannot obtain effective tool length data like this.In addition, the tip cutters to be measured such as diameter less than 2 millimeters cutters to be measured and drill bit because of end can induction area very little, even if there is actual contact with proximity switch also cannot respond to triggering.
Can be used for of this tool detection devices, detects minor diameter easily broken cutter to be measured; therefore the advantage of contact block is to replace cutter to be measured to contact with proximity switch and constant contact area; thus make triggering distance keep stable; can can receive to trigger and record present level after the signal of telecommunication and contrast with height of foundation by effective Feedback cutter to be measured tool long degree ﹐ lathe, differ by more than certain value and be then judged to be that namely breaking sends and report to the police and shut down.
In addition, those skilled in the art also can do other change in the utility model spirit, and certainly, these changes done according to the utility model spirit, all should be included in the utility model scope required for protection.
