The specific embodiment
The practical implementation of the permanent magnet suspender of the utility model for example Fig. 1 is extremely shown in Figure 3; This permanent magnet suspender comprises sucker 1; This sucker 1 is mainly processed by weak permeability magnetic material or non-magnet_conductible material; The bottom surface of this sucker 1 is to be used for the adsorption plane of adsorbate materials and parts and on this adsorption plane, to be embedded with the magnetic head 2 that is used to adsorb material; The magnetic pole that is provided with permanent magnet and magnetic head 2 two ends in this magnetic head 2 is arranged along the adsorption plane bearing of trend of sucker 1, and in the present embodiment, this magnetic head 2 comprises two alternate symmetrically arranged lobe pieces 21,22; Two lobe pieces 21,22 constitute by magnetizer; At two lobe pieces 21, be provided with the plane of opposing parallel between 22, between the relative plane of two lobe pieces 21,22, clamped the symmetrically arranged permanent magnet 23 of two relative spacings, the magnetic pole at identical and its two ends of the pole orientation of this two permanent magnet 23 respectively with 21,22 corresponding joining of two lobe pieces; At two lobe pieces 21, casting epoxy resin 24 constitutes magnetic head 2 with two permanent magnets 23 and two lobe pieces, 21,22 bonding being integral between 22, thereby make two lobe pieces 21,22 constitute the S utmost point and the N utmost point of magnetic head 2 respectively.On the end face of two lobe pieces 21,22, also be provided with by what permeability magnetic material constituted and take off magnetic sheet 3; This takes off magnetic sheet 3 and drives in external force and have down and magnetic head 2 two ends magnetic poles the taking off magnetic potential and breaking off it and 2 liang of magnetic pole bonded assemblys of magnetic head separating position of formation magnetic conductive loops of fitting; In the present embodiment; Be in when taking off magnetic potential and the end face of two lobe pieces 21,22 is fitted simultaneously when taking off magnetic sheet 3, thereby when taking off magnetic sheet 3 and be in separating position, can only contact or break away from fully magnetic head 2 disconnection magnetic conductive loops with one of them lobe piece.For reducing leakage field; This sucker 1 mainly form up and down by relative spacing by opposed top board 11 and base plate 12 and the connecting panel that is connected between the roof and floor; In base plate 12, be embedded with two around sucker 1 center well-distributed magnetic head 2; Take off the bearing pin 13 of magnetic sheet 3 through being fixedly arranged on base plate 12 centers and rotate and be assemblied in roof and floor 11, the gap between 12 and fit with the upper surface of base plate 12 all the time, take off at this and also be fixed with the driving handle 31 that stretches out sucker 1 edge on magnetic sheet 3.
Hang when getting material at needs; At first pull driving handle 31 and make and take off magnetic sheet 3 deflections and get back to separating position, thereby break away from itself and the contacting of two magnetic heads 2, when material 4 contacts with the magnetic head 2 of the bottom surface of sucker 1; 4 whiles of material fit with two lobe pieces 21,22 in the magnetic head 2; Because it is low, as shown in Figure 4 that the magnetic resistance of the material 4 that is adsorbed is compared airborne magnetic resistance, therefore; Magnetic line of force major part between 2 liang of magnetic poles of magnetic head this moment constitutes magnetic conductive loop through the material 4 that is adsorbed, thereby on the adsorption plane that is adsorbed on sucker 1 that material 4 labor are solid; When needs unloading material; Pulling driving handle 31 makes and takes off magnetic sheet 3 and turn to the two lobe pieces 21,22 that take off magnetic potential and magnetic head 2 around bearing pin 3 and fit simultaneously; As shown in Figure 5, process by permeability magnetic material owing to take off magnetic sheet 3, so the magnetic line of force between 2 liang of magnetic poles of magnetic head forms two magnetic conductive loops up and down through the magnetic sheet 3 that takes off on magnetic head 2 upper surfaces with the material 4 that the bottom adsorption plane is adsorbed simultaneously; Therefore weakened the suction of 2 times magnetic conductive loops of magnetic head by taking off the last magnetic conductive loop that magnetic sheet 3 constitutes to material 4; Thereby can easily material 4 be taken off, pull driving handle 31 after taking off and make and take off magnetic sheet 3 contrarotations and get back to separating position, break away from magnetic head 2 in being connected of two lobe pieces 21,22; Break off the magnetic conductive loop on magnetic head 2 tops, can recover the normal sorption power of 2 pairs of materials of magnetic head.
The utility model is not limited to the foregoing description, and in concrete the application, magnetic head also can wholely adopt permanent magnet to process, as long as the two ends magnetic pole of permanent magnet is arranged along pressure head adsorption plane bearing of trend; Be located at taking off magnetic sheet and also can adopting drive mechanism horizontal pull moves or the integral translation mode is installed in the pressure head along the magnetic head upper surface of magnetic head top, it is all within the protection domain of the utility model.
The utility model simple in structure; It is utilized in magnetic head top and forms new magnetic conductive loop and weakened the adsorption affinity of magnetic head to workpiece; Make the unloading of workpiece convenient, fast; The defective time saving and energy saving, that it has overcome material unloading difficulty when magnetic head magnetic force is big in the sucker can be widely used in the various permanent magnet suspenders.
