Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
As depicted in figs. 1 and 2, from the two-dimension translational structural scheme of mechanism containing locking-unlocking device and locking-unlocking device exploded perspective view it can be seen that this locking-unlocking device mainly includes dead electricity type electric magnet 3, electric magnet supporting seat 4, Y-direction clamping block 7, X is to clamping block 8.
Of the present invention locking-unlocking device is expanded on further: as it is shown on figure 3, dead electricity type electric magnet 3 overall dimensions is 20 × 23mm, mainly by electric magnet 301, insulation sleeve 302 and permanent magnet 303 form below in conjunction with Fig. 1, Fig. 2, Fig. 3 and Fig. 4.When being not powered on, its suction is for up to 60～70N.As shown in Figure 4, electric magnet supporting seat 4 is main is made up of groove 401, cavity 402, circular hole 403, U-shaped hole 404 and fixing end 405.Wherein cavity 402 internal diameter is 20mm, and external diameter is 23mm, long for 25mm.X is to the cylindrical structure that clamping block 8 is with fixing end, and cylinder external diameter is 20mm, and thickness is 5mm, and its fixing end length is 10mm.The L-shaped short end length of Y-direction clamping block 7 is 5mm, and long end length is 10mm.X is 150mm to translation carrier table 5 effective travel.Y-direction translation carrier table 12 effective travel is 15mm.
After dead electricity type electric magnet 3 circumferencial direction and bottom are coated with one layer of DG-4 glue bonding with electric magnet supporting seat 4 cavity and tighten with trip bolt 2, solidify 24 hours.The electric magnet assembled is supported 4 be connected by two trip bolts 9 to supporting seat 13 with X.
X is connected to translation carrier table 5 by 2 trip bolts 10 to the fixing end of clamping block 8 with X, and X is to clamping block 8 cylinder outer face and the tight adhesive in electric magnet 3 outer face.
The long end of L-shaped of Y-direction clamping block 7 is translated carrier table 12 with Y-direction and is connected by 2 trip bolts 6, and its L-shaped short end and electric magnet supporting seat groove 401 are matched in clearance, and its short end protrudes fully in groove 401.
Dead electricity type electric magnet 3 is passed into 24V DC voltage, and the retention time is 10s.Meanwhile, X passes into 12V DC voltage to drive motor 1, drives X to translate to translation carrier table 5 with the speed of 1mm/s, and when translation distance reaches 4mm, dead electricity type electric magnet 3 is negligible to the suction of clamping block 8 to X, it is achieved X is to unblock.When X translates 4mm to translation carrier table 5, Y-direction clamping block 7 and electric magnet supporting seat groove 401 depart from, it is achieved Y-direction translation unlocks.When Y-direction drive motor 11 passes into 12V DC voltage, Y-direction translation carrier table 12 can be carried out the work.
The workflow of this two-dimension translational mechanism locking-unlocking device is: utilize the dead electricity type electric magnet 3 self permanent magnet 303 suction in dead electricity situation, firmly holds to realize X to locking by X to clamping block 8.The L-shaped short end of Y-direction clamping block 7 matches with electric magnet supporting seat groove 401 to realize Y-direction locking.After two-dimension translational mechanism enters the orbit, the magnetic force that electric magnet 301 obtains electromagnetic force and the permanent magnet 303 produced after 24V DC voltage is equal in magnitude, in opposite direction so that the suction between clamping block 8 and dead electricity type electric magnet 3 is zero, it is achieved X is to unblock.Starting X to drive motor 1 so that X moves to translation carrier table 5, after X moves 4mm to translation carrier table 5, the L-shaped short end of Y-direction clamping block 7 departs from supporting seat groove 401, and Y-direction realizes unlocking, and the two-dimension translational structural scheme of mechanism after unblock is as shown in Figure 5.
