Embodiment
Can know by Fig. 1～6; The fixing locating device of strong magnets absorption by left Attraction block 1, right Attraction block 1 ', strong magnets 2, rectangle magnetic line of force division board 3, dolioform magnetic line of force division board 3 ', iron termination 4, nylon locating sleeve 5, push-and-pull post 6, double-screw bolt 7 and housing 8 constitute; Housing 8 is a rectangular parallelepiped; The centre position, top is provided with threaded hole and cooperates with double-screw bolt 7, and double-screw bolt 7 is provided with through hole; A left side Attraction block 1, right Attraction block 1 ', strong magnets 2, rectangle magnetic line of force division board 3, dolioform magnetic line of force division board 3 ' and housing 8 usefulness metal adhesives be fixed together, form the strong magnets suction base; Strong magnets suction base interposition is equipped with through hole, and left-right symmetric has two grooves below the through hole horizontal line, studs with rectangle magnetic line of force division board 3 in the groove, and rectangle magnetic line of force division board 3 is parallel with the bus of strong magnets suction base through hole; The bottom of strong magnets suction base, have a groove near location right; The groove left side is left Attraction block 1; Groove the right be right Attraction block 1 ', stud with in the groove dolioform magnetic line of force division board 3 ', dolioform magnetic line of force division board 3 ' vertical with the through hole bus of strong magnets suction base; Strong magnets suction base bottom is the spill circular arc, and its arc diameter is consistent with the specimen diameter;
According to the test specimen shape, other shapes can be made in strong magnets suction base bottom.
The through hole wringing fit of two nylon locating sleeves 5 and strong magnets suction base; Be placed on through hole right ends position respectively, two push-and-pull posts 6 pass right ends nylon locating sleeve 5, drive strong magnets 2 move left and right in the through hole of strong magnets suction base through iron termination 4.
Through manually move push-and-pull post 6 change strong magnets magnetic line of force direction, make the fixing locating device of strong magnets absorption be in work or closed condition.Because the permanent magnetism of strong magnets, 2 two iron terminations 4 of strong magnets and top fixing push-and-pull post 6 thereof are attached together.
During work; Push-and-pull post 6 is moved to the right side of strong magnets suction base; Strong magnets 2 centers are relative with dolioform magnetic line of force division board 3 ' center, strong magnets 2 and left and right sides Attraction block 1,1 ' combine simultaneously, and produce the magnetic force conductor; Magnet left and right sides Attraction block 1,1 ' bottom spill arc surface have constituted a pair of vertical magnetic pole, and the metal material and the test specimen of magnetisable material firmly held; After test is accomplished; Push-and-pull post 6 is moved to the left side (Fig. 1 position) of strong magnets suction base, and 2 of strong magnets combine with left Attraction block 1, do not produce the magnetic force conductor; Magnet left and right sides Attraction block 1,1 ' bottom spill arc surface do not have magnetic pole, and the fixing locating device of strong magnets absorption is in closed condition.
The principle of work of the utility model:
1, according to the characteristic of magnet magnetic line of force N/S with how to accomplish to make this magnetic support at a distance from the effect of magnetic, have only the material that can be adsorbed onto on the magnet just can play the effect that cuts off magnetic field, and material is thick more, good more at a distance from the effect of magnetic.
(the magnetic support housing is that ductile iron material is the material that can be magnetized, can be by attraction as iron, nickel, cobalt and alloy thereof.Do not have the character that can be magnetized like copper, tin, aluminium etc., just can not be attracted by magnet.)
2, explanation shown in Figure 1: according to principle how to accomplish to cut off magnetic field, at first mentality of designing is that magnet suction base housing 8 is the whole material that can be magnetized, and reaches the effect of magnet suction base housing 8 outside no magnetic.Be convenient to processing and adopt the magnesium iron housing.Adopt not have the material aluminium sheet 3,3 that can be magnetized ' isolate each other with 1,1 ' two of magnet suction base housing 8 magnet adsorption plane, making 1,1 ' two of magnet adsorption plane respectively is an independently magnetic force conductor, also can be called " magnet newly ".Magnet has polarity, and like pole repels each other, and opposite pole is inhaled mutually.Because when iron was magnetized, the N utmost point of " new magnet " was extremely relative with the S of original magnet, so magnet can be inhaled iron.
3, moving the push-and-pull assembly change magnetic line of force through manual magnet makes permanent magnet be in work or closed condition.When permanent magnet was in running order, the matrix suction face of 1,1 ' two bottom of magnet adsorption plane had constituted a pair of vertical magnetic pole, and the workpiece of ironware material is held firmly.
When permanent magnet was in closed condition, the matrix suction face of 1,1 ' two bottom of magnet adsorption plane did not have magnetic pole, so can not the workpiece of ironware material be held.
4, the closed condition of magnet is when moving push-and-pull assembly to Fig. 1 left side through manual push-and-pull magnet; Magnet produces the effect that cuts off magnetic field when moving the push-and-pull assembly and combining fully with magnet adsorption plane 1; The matrix suction face of bottom does not have magnetic pole, so can not the workpiece of ironware material be held.
The duty of magnet is when moving push-and-pull assembly to Fig. 1 right side through manual push-and-pull magnet; Magnet moves push-and-pull assembly and magnet adsorption plane 1,1 ' generation magnetic force conductor when combining fully; The matrix suction face of 1,1 ' two bottom of magnet adsorption plane has constituted a pair of vertical magnetic pole also can be called " new magnet ", and the workpiece of ironware material is held firmly.
