Abstract
The utility model discloses a directional magnetic force device belonging to a tool used for directionally attracting ferromagnetic substance. The directional magnetic force device is composed of a permanent magnet steel 4, a concentrating flux sleeve 2, non-magnetic medium 3 and a handle component 1. The periphery of the permanent magnet steel is sheathed with the concentrating flux sleeve. One layer of non-magnetic medium is arranged at the side surface of the permanent magnet steel and the concentrating flux sleeve. The front end of the concentrating flux sleeve is provided with an opening. The back end is closed and is connected with the handle component. The utility model can conveniently take out the parts which drop into mechanism devices and are useless. The directional magnetic force device can be used as an ordinary tool and can be used in the technical field of mechanical industry, domestic appliances, etc.
Description
The utility model relates to a kind of directed instrument that attracts ferromagnetic material.
It is known general knowledge that permanent-magnet steel has suction to ferromagnetic material, has been widely used in all trades and professions, as the crane sucker that permanent-magnet steel (or electromagnet) is done, the pencil box of carry magnet etc.But attract the instrument of ferromagnetic material unprecedented as orientation it, in the manufacturing of plant equipment, installation, maintenance process, run into such situation through regular meeting, be about to certain useless parts and fall into (as nut, wrench etc.) in the equipment, this is the thing that bothers very much for the operator, if with hand or by other instrument can then it doesn't matter with its convenient taking-up; But useless sometimes parts are fallen in the equipment; beyond reach; also can't take out by existing instrument; this situation runs into through regular meeting in practical operation; existing settling mode is; mini-plant can take out its dismounting or upset with useless part, for main equipment sometimes engineers and technicians must rack one's brains, taking very big strength could take out it.People once attempted with magnet it being taken out, and the Distribution of Magnetic Field of but suffering from magnet is space three-dimensional magnetic field, and its suction all exists in any direction, were easy to be held by the ferromagnetic material of equipment itself, can't be near the useless parts of falling into.
The purpose of this utility model is to add flux sleeve in the permanent-magnet steel periphery, makes the magnetic force orientation concentrate on front end, makes a kind of directed instrument that attracts ferromagnetic material, like this, just can it be taken out easily in the clear near the useless parts of falling in the plant equipment.
The major technique formation that realizes above-mentioned utility model purpose is: this orientation magnetic force device is by permanent-magnet steel, flux sleeve, non-magnetic media, handle are formed, flux sleeve on the permanent-magnet steel outer race, the side of permanent-magnet steel and flux sleeve is provided with one deck non-magnetic media, the flux sleeve front opening, back-end closure also is connected with Handleset.
Because permanent-magnet steel has put the flux sleeve of front opening, thereby there is not magnetic field basically at the position that flux sleeve is arranged, just there is directional magnetic field at front end, and because flux sleeve adopts magnetic conduction substance, make front end magnetic flux increase, suction increases, and can stretch into easily in the plant equipment by Handleset, and can not be subjected to the obstruction of the ferromagnetic material of equipment itself, the useless parts of falling in the equipment are taken out.Certainly described useless parts must be ferromagnetic materials.
Be a kind of most preferred embodiment of the present utility model shown in the accompanying drawing, the utility model described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the outline drawing of directed magnetic force device.
Fig. 2 is the cutaway view of directed magnetic force device.
Fig. 3 is the Distribution of Magnetic Field figure of directed magnetic force device.
The structure of directed magnetic force device mainly is the flux sleeve made from magnetisable material (as mild steel, medium carbon steel etc.) at cylindrical magnet steel 4 outer race last layers 2, and flux sleeve 2 is the cylindrical of hollow, and permanent-magnet steel 4 is enclosed in wherein; Flux sleeve 2 front openings, back-end closure also has a hole, and this hole is in order to connect Handleset 1.Between permanent-magnet steel 4 and flux sleeve 2, one deck non-magnetic media 3 is set,, makes Distribution of Magnetic Field be delivered to front end by flux sleeve, as shown in Figure 3 along the rear end of permanent-magnet steel in case leakage magnetic flux is excessive.
In the present embodiment, permanent-magnet steel 4 adopts cylindrical, and its reason is under the condition of identical suction, and the circular area minimum certainly, adopts other shape also can.For increasing suction, reduce the volume of directed magnetic force device, permanent-magnet steel is preferably selected NdFeB material for use.
The effect of flux sleeve is to produce directional magnetic field, and the magnetic field of permanent-magnet steel itself is the space three-dimensional distribution, adds that the magnetic field of the directed magnetic force device behind the flux sleeve 2 then concentrates on front end, and there is not magnetic field basically in other position.As shown in Figure 3, through test of many times, as desire to obtain maximum directed magnetic force effect, the area of flux sleeve 2 should be suitable with the area of permanent-magnet steel 4, and like this, the magnetic field at permanent-magnet steel 4 rear portions can be transmitted to front end losslessly.In order to guarantee fixedlying connected of permanent-magnet steel 4 and flux sleeve 2, to avoid in use, permanent-magnet steel 4 is by the ferromagnetic material sucking-off, should stick with glue between permanent-magnet steel 4 and the flux sleeve 2 to connect.
As everyone knows, the magnetic field of permanent-magnet steel is very strong, in order to make directed magnetic force device in that the time spent does not have magnetic disturbance, perhaps need regulate the needs of magnetic force size in some occasion, the utility model also is added with antifreeze plate 5 at the front end of directed magnetic force device, antifreeze plate 5 can be made laminated structure, every thickness difference, the size of regulating magnetic force by the antifreeze plate of changing different-thickness.Antifreeze plate is to rely on suction to be connected with directed magnetic force device.As for shape, the structure of Handleset 1, not inventive point of the present utility model place, look concrete condition and adopt different Handlesets, as coiled pipe, flexible link, straight-bar, tortuous bar, expansion link, a class, screwdriver etc.
Because the utility model has solved convenience effectively and taken out the technical task of falling into the useless parts in the plant equipment, and volume is little, cost is low, thereby can be widely used in mechanical industry, technical fields such as household electrical appliance as a kind of general tool.
