Abstract

The utility model relates to a controllable universal magnetic disk which belongs to a device provided with a permanent magnet for regulating magnetic variable. The utility model makes the generation and the disappearance of magnetic force have free control from a plurality of tens of kilograms to a plurality of tens of tons, makes the attractive force of the permanent magnet enhanced by several times on the original basis and has the advantages of less magnet material consumption, magnetic force enhancement and low cost. The utility model is widely used on an industry to replace an electromagnetic crane, replace a base of a dial gauge, substitute a base of an electromagnetic attracting disk of a magnetic force drill and substitute various electromagnetic devices; the controllable universal magnetic disk can be made into lamp maintaining bases of various devices and can be used as a connecting ground wire of an electric welding device, etc. The controllable universal magnetic disk is composed of an outer frame, a magnetic conductor, a permanent magnetic block, an attracting plate, a screw rod for controlling, a main wire, a sliding bearing, a turn knob, a rotating frame and a rotating handle.

Description

Controllable magnetic disk

The utility model belongs to and has permanent magnet in order to regulate the device of magnetic variable.

At present, the industrial electromagnetism of using morely is used widely at aspects such as electromagnetic lifter, magnetic force brills, and permanent magnetism is used seldom in these areas.The electromagnetism consumed energy is big, and can not use in water and various rugged surroundings.

The purpose of this utility model is to provide with the permanent magnet popularization and application in industrial regulatable omnipotent disk, it magnetic force is produced and the magnetic force disappearance control is freely from several kilograms to tens tons.

The utility model is finished with following mode: it has outrigger 1, two row's quantity specifications is housed in outrigger 1 equates and the corresponding magnetite of installing; Every row's magnetite constitutes by the permanent magnets more than 1 or 13 and the N utmost point and N is extremely adjacent or the S utmost point is extremely adjacent with S between per 2, and every row's magnetite is inlaid in the magnetic conductor 2; Between above-mentioned two magnetites that row's quantity specifications equate and correspondence is installed is that the N utmost point is extremely adjacent with S between per 2; First row promptly goes up row's magnetite central authorities turret 5 is housed, and this turret 5 and first row's magnetite link to each other, the mobile device that is made of female 7, screw mandrel 6, sliding bearing 4, knob 8 that its middle part is equipped with that may command first row's magnetite moves around; The whirligig of the may command first row's magnetite rotation that is made of turning handle 9 and turret 5 is equipped with at its top; Second row promptly arranges the magnetite bottom down suction disc 10.

Controlled omnipotent disk uses permanent magnet not want consumed power, can use in water and various rugged environment.It is controlled that magnetic force produces and magnetic force disappears, and control freely from several kilograms to tens tons.Make the suction of permanent magnetism improve several times on original basis, reduce the consumption of magnetite material, magnetic force strengthens, and reduces cost.Make a lot of disk sets can close magnetic force and generation magnetic force.Be widely used in industrial replacement electromagnetic lifter, replace the dial gauge base; Replace magnetic force to bore the magnechuck base, replace various calutrons; Can make the trouble light base of various device, can be used as the connection ground wire of electric welding equipment.

Now in conjunction with the accompanying drawings the utility model is described in further detail.

Fig. 1, Fig. 2 are controlled omnipotent disk structure synoptic diagram, and wherein Fig. 1 is a front view;

Fig. 2 is the A-A step profile of Fig. 1.

With reference to Fig. 1～Fig. 2, the utility model be by two row's quantity specifications equate and the corresponding magnetites of installing between relative motion, when the N of first row's magnetite extremely to the N utmost point of second row's magnetite, S during extremely to the S utmost point, magnetic line of force output sucks suction disc 10; When the N of first row's magnetite extremely to the S utmost point, S of second row's magnetite during extremely to the N utmost point, the magnetic line of force forms the loop in inside, does not have magnetic line of force output, and suction disc 10 is put down.Two row's magnetites are adjusted its relative position by following two kinds of modes: 1, when turning knob 8, screw mandrel 6 drives female silk 7 and moves in the groove of turret 5, owing to mother's 7 and first row's magnetite links to each other, thereby at this moment first row's magnetite moves the relative position that magnetite is arranged in adjustment and second.2, when rotation turning handle 9, driving turret 5 rotates in the hole of outrigger 1, because the column part of turret 5 cooperates with the interporal lacuna of outrigger 1, thereby the female silk 7 that drives in the groove of turret 5 rotates, promptly drive first row's magnetite and turn to till 180 °, thus the relative position of adjustment and second row's magnetite.The utility model by the relative position of adjusting two row's magnetites magnetic force is produced and magnetic force disappears, and from several kilograms to tens tons, controls freely, for wide field and approach have been opened up in the practical application of permanent magnetism.For example: 1. at electric welding equipment as connecting ground wire, magnetic force is opened, workpiece firmly can be connected with ground wire, workpiece is sticking steady, do not need artificial clamping, can not burn out workpiece because of loose contact; 2. adopt the nickel chromium triangle cobalt easily to demagnetize at present as the dial gauge base, present technique adopts Ru-Fe-Mn permanent magnetism can not demagnetize, and existing dial gauge base is a V-type, and contact area is little, and this structure interface is the plane, and area is big, efficient is high.Existing dial gauge is that 1 permanent magnets 3 driving torque is big, and this structure is 2 permanent magnets 3 up and down, rotates wherein 1, and driving torque is little.3, boring the present magnetic force of base as magnetic force, to bore what use be electromagnet, and consumed power has a power failure if meet suddenly when work on the inclined-plane, and magnetic force bores and also can fall down from the inclined-plane, and controlled omnipotent disk use is solid and reliable; 4, compare few, energy-conservation, the province's expense of electromagnetism lifting additional facilities as hoisting apparatus; 5, the base that can be used for the motor vehicle repair lamp, automobile can be bonded at trouble light and are used for illumination Anywhere after being out of order night, also can be used for the trouble light of machining apparatus; 6, can be used as salvaging ironware usefulness in the water; 7, can replace most electromagnetic equipments.The utility model also has extensive use in others, makes permanent magnetism obtain popularizing and using.
