Abstract
The invention provides a locking and unlocking device of a two-dimensional translating mechanism. The locking and unlocking device comprises a power-loss type electromagnet, an electromagnet support, an X-direction locking block and a Y-direction locking block. When the power-loss type electromagnet is not electrified, an X-direction translating carrier is locked through attraction force between the X-direction locking block and the power-loss type electromagnet; a Y-direction translating carrier is locked through fastening of an L-shaped short end of the Y-direction locking block and a groove of the electromagnet support. When the power-loss type electromagnet is electrified, attraction force between the X-direction locking block and the power-loss type electromagnet is lost, X-direction unlocking is realized; an X-direction driving motor drives the X-direction translating carrier to move, so that the L-shaped short end of the Y-direction locking block is separated from the groove of the electromagnet support, and Y-direction unlocking is realized.

Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
As depicted in figs. 1 and 2, from two-dimension translational structural scheme of mechanism and locking-unlocking device exploded perspective view containing locking-unlocking device, can find out, this locking-unlocking device mainly comprises dead electricity type electromagnet 3, electromagnet supporting base 4, Y-direction clamping block 7, X-direction clamping block 8.
Below in conjunction with Fig. 1, Fig. 2, Fig. 3 and Fig. 4, further set forth locking-unlocking device of the present invention: as shown in Figure 3, dead electricity type electromagnet 3 boundary dimension are 20 * 23mm, mainly by electromagnet 301, insulating bush 302 and permanent magnet 303 form.While switching on, its suction is not for can reach 60～70N.As shown in Figure 4, electromagnet supporting base 4 mainly consists of groove 401, cavity 402, circular hole 403, U-shaped hole 404 and fixed end 405.Wherein cavity 401 internal diameters are 20mm, and external diameter is 23mm, and long is 25mm.X-direction clamping block 8 is the cylindrical structure with fixed end, and cylindrical body external diameter is 20mm, and thickness is 5mm, and its fixed 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-direction translation carrier table 5 effective travels are 150mm.Y-direction translation carrier table 12 effective travels are 15mm.
Dead electricity type electromagnet 3 circumferencial directions and bottom are applied after one deck DG-4 glue bonding with electromagnet supporting base 4 cavitys and with fastening screw trip bolt 2, tighten curing 24 hours.The electromagnet assembling is supported to 4 to be connected by two fastening screw trip bolts 9 with X-direction supporting base 13.
X-direction clamping block 8 fixed ends are connected by 2 fastening screw trip bolts 10 with X-direction translation carrier table 5, X-direction clamping block 8 cylindrical body exterior edge faces and the electromagnet 3 tight adhesives in exterior edge face.
The L shaped long end of Y-direction clamping block 7 is connected by 2 fastening screw trip bolts 6 with Y-direction translation carrier table 12, and its L shaped short end and electromagnet supporting base groove 401 are Spielpassung, and its short end extend in groove 401 completely.
Dead electricity type electromagnet 3 is passed into 24V VDC, and the retention time is 10s.Meanwhile, X-direction drive motor 1 passes into 12V VDC, drives X-direction translation carrier table 5 to carry out translation with the speed of 1mm/s, and when translation distance reaches 4mm, the suction of 3 pairs of X-direction clamping blocks 8 of dead electricity type electromagnet can be ignored, and realizes X-direction release.When X-direction translation carrier table 5 translation 4mm, Y-direction clamping block 7 departs from electromagnet supporting base groove 401, realizes Y-direction translation release.When Y-direction drive motor 11 passes into 12V VDC, 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 self permanent magnet 303 suction of dead electricity type electromagnet 3 in dead electricity situation, X-direction clamping block 8 is firmly held to realize X-direction locking.The L shaped short end of Y-direction clamping block 7 matches to realize Y-direction locking with electromagnet supporting base groove 401.After two-dimension translational mechanism enters the orbit, electromagnet 301 obtains the electromagnetic force that produces after 24V VDC and the magnetic force equal and opposite in direction of permanent magnet 303, opposite direction, and making the suction between clamping block 8 and dead electricity type electromagnet 3 is zero, realizes X-direction release.Start X-direction drive motor 1, X-direction translation carrier table 5 is moved, when X-direction translation carrier table 5 moves after 4mm, the L shaped short end of Y-direction clamping block 7 departs from supporting base groove 401, and Y-direction realizes release, and the two-dimension translational structural scheme of mechanism after release as shown in Figure 5.
