Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model route-variable electromagnet.
Fig. 2 is the left view of the push rod of the utility model route-variable electromagnet.
Fig. 3 is the use state reference map of the utility model route-variable electromagnet.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but can not be used for limiting scope of the present utility model.
The structure of the utility model route-variable electromagnet as Figure 1-3, comprise lower yoke 1, upper magnet yoke 3, electromagnet 2, push rod 8, iron core 7, spring 4 and adjusting nut 5, described lower yoke 1 is fixedly connected with described upper magnet yoke 3, and embeds and be provided with electromagnet 2 therein; The center of described lower yoke 1 is provided with through hole 102, and described through hole 102 inwalls are provided with groove 103, is provided with projection 801 on described push rod 8, and described protruding 801 embed in described groove 103 and are located in described through hole 102; The top of described push rod 8 is provided with screw thread 803, on described iron core 7, offers blind hole 702, and described push rod 8 is threaded connection with iron core 7; Described iron core 7 is located on described upper magnet yoke 3, on the top of described iron core 7, is arranged with spring 4, and the top of described iron core 7 is arranged with adjusting nut 5, and described adjusting nut is fixedly connected on described iron core 7 by nut 6.
As optimization, the lower end of described iron core 7 is set to taper surface 703, and offer bellmouth 101 on the through hole 102 of described lower yoke 1, described taper surface 703 can be realized close fit with described bellmouth 101, described taper surface 703 can make iron core 7 obtain larger magnetic force with respect to plane, meets the user demand of electromagnet.
As optimization, described iron core 7 adopts multidiameters, and on step surface, is provided with cushion pad 701, and described multidiameter setting can be realized the range amount of route-variable, prevents from excessively regulating adjusting nut 5 and causes iron core 7 and push rod 8 to depart from, and causes electromagnet to damage.In addition cushion pad 701 can reduce the impulsive force between iron core 7 and upper magnet yoke 3 when iron core 7 resilience, reduces operating noise.
As optimization, on described push rod 8, be provided with boss 802, the diameter of described boss 802 is greater than the diameter of through hole 102 in described lower yoke 1, and described boss 802 is for limiting the push rod 8 upwards displacement of maximum in the axial direction.
As optimization, on described adjusting nut 5, evenly offer anti-slip tank 501, described anti-slip tank 501 can provide enough frictional force, convenient operation.
Specifically, during described work of electromagnet, first coil 2 energisings are magnetic field energy by electric energy conversion, and iron core 7 moves to the direction near lower yoke 1 under the effect in magnetic field, and drives push rod 8 to move down, and realizes and is pulled object traction to final position.After power-off, iron core 7 can move up under the elastic force effect of spring 4, thereby drive push rod to realize, resets.
When needs change stroke, only need to rotate adjusting nut 5, adjusting nut 5 is fixedly connected with iron core 7, so iron core 7 also rotates; The projection 801 arranging on described push rod 8 embeds in described groove 103 and is located in described through hole 102, and push rod 8 can not relatively rotate.When iron core 7 rotates, realize the change of iron core 7 and push rod 8 relative positions, thereby realize the change of electromagnet stroke.
The utility model route-variable electromagnet adopts iron core and the adjustable design of push rod relative position, realizes the change of electromagnet stroke, has the features such as simple in structure, easy to operate.
These are only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
