Further, mounting panel is provided with first riser, second riser and base plate, first riser and second riser are fixed on the base plate, first riser is near location-plate, the compression spring is arranged between first riser and second riser, secondary bar can move between first riser and second riser, and linear electric motors are fixed on the outside of second riser.
Further, be provided with location hole at first riser, alignment pin can reciprocatingly slide in location hole, and its tail end only can block the inboard at first riser.
Further, the front end of alignment pin extends forward and shrinks and is taper.
Further, mounting panel is fixed on the fixed mount, and location-plate is fixed on the movable stand, and movable stand can move up and down with respect to fixed mount.
Compared with prior art, linear motor positioning device of the present utility model comprises linear motor assembly and location-plate, linear motor assembly is fixed on the mounting panel, mounting panel and location-plate can move up and down mutually, linear motor assembly comprises linear electric motors, compression spring and alignment pin, linear electric motors are fixed on the mounting panel, and alignment pin is arranged on an end of the secondary bar of linear electric motors.By cooperating between the location hole on alignment pin and the location-plate, can limit moving up and down between version and the location-plate is installed, prevent that location-plate from sliding.The utlity model has simple in structure, accurate positioning, reaction is fast, can be widely used in the equipment of lifting, translational motion.
Description of drawings
Fig. 1 is the schematic perspective view of a preferred embodiment of the present utility model;
Fig. 2 is the schematic perspective view under the dc motor assembly "on" position among Fig. 1;
Fig. 3 is the schematic perspective view under the dc motor assembly off-position among Fig. 1.
Embodiment
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Please refer to shown in Figure 1ly, is a preferred embodiment of the present utility model, comprises linear motor assembly 1 and location-plate 2, and linear motor assembly 1 is fixed on the mounting panel 3, and mounting panel 3 can move up and down mutually with location-plate 2.
Be provided with the location hole 21 that can allow alignment pin 13 pass through at location-plate 2, alignment pin 13 can be socketed in the location hole 21 of location-plate 2, and restriction location-plate 2 moves.
Please refer to shown in Figure 2, when linear electric motors 11 energisings, secondary bar 112 moves at the axis of the elementary body 111 in the effect lower edge, magnetic field of elementary body 111, and drive alignment pin 13 looses from the location hole 21 of location-plate 2, removed the restriction to location-plate 2, location-plate 2 can freely move up and down.At this moment, compression spring 12 is in the contraction pressured state.
Please refer to shown in Figure 3ly, when linear electric motors 11 outage, automatically reset after compression spring 12 loses constraint, and drive secondary bar 112 and alignment pin 13 is mobile together.The tail end 131 of alignment pin 13 only can block in the inboard 311 of first riser 31, and its front end 132 springs in the location hole 21 of location-plate 2, and restriction location-plate 2 moves up and down.
During actual the use, the operating state of linear electric motors 11 is controlled by a controller (not shown).Mounting panel 3 is fixed on the fixed mount (not shown), and location-plate 2 is fixed on the movable stand (not shown), and movable stand can move up and down with respect to fixed mount.During normal condition, the linear electric motors 11 that are fixed on the fixed mount are in off-position, and alignment pin 13 stretches out under the effect of compression spring 12 and is inserted in the location hole 21 of location-plate 2, the movement of restriction movable stand.At this moment, this device is in blocking.In order to strengthen the stablizing effect of movable stand, can set up a plurality of devices in the surrounding of fixed mount.
When the mobile movable stand of needs, at first to remove the blocking of this device.Send control signal for linear electric motors 11 by controller, move behind the linear electric motors 11 controlled signals.The secondary bar 112 of linear electric motors 11 drives alignment pin 13 retractions and leaves location hole 21, compresses spring 12 simultaneously, makes it be in pressured state.Movable stand does not have the constrained of alignment pin 13 to move freely.At this moment, this device is in unlocking condition.
After movable stand was removed, controller disconnected the power supply of linear electric motors 11.After linear electric motors 11 outages, alignment pin 13 stretches out from location hole 34, and this device enters blocking again.But, do not hinder the movement of movable stand this moment.The electrical working time that very big minimizing linear electric motors 11 are set like this can saves energy.
When movable stand will come back to latched position, controller gave linear electric motors 11 energisings immediately.After linear electric motors 11 energising, this device enters unlocking condition again, allow movable stand by and enter into latched position.Then, controller gives linear electric motors 11 outages again immediately, and this device enters blocking again.Movable stand pin 13 locking that is positioned again can not be moved, and finishes a duty cycle.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
