Detailed Description
As shown in fig. 1 to 6, in the positioning device, the middle position of the metal housing 300 that can be magnetized is respectively provided with a groove 310 for fixing the square bar-shaped magnetic steel 100 at the upper part from top to bottom along the H line (central symmetry line), a cylindrical hole 330 for the rotation of the rotatable square bar-shaped magnetic steel 200 is provided at the middle part, and a V-shaped groove 320 is provided at the lower part; the magnetic steel 200 is fixed in the non-magnetizable rotating block 210, and is driven to rotate in the cylindrical hole 330 by pulling the switch handle 500, the rotating range is about 115 to 130 degrees, and the rotating range is reasonable when the rotating range is 115 to 125 degrees; the lengths of the magnetic steels 100 and 200 are equal, and the sectional areas are also equal; when the magnetic steel is in a rotating 0-bit (shown in figure 3) state, the polarities (S pole and N pole) of the upper magnetic steel and the lower magnetic steel are the same and parallel; when the positioning device can rotate to 120 degrees (which is the optimal value of the maximum rotation angle and is shown in fig. 4), the effect is optimal, at this time, because the polarity relationship of the upper magnetic steel 100 and the lower magnetic steel 200 changes (see the marks and changes of the N pole surface and the S pole surface of each magnetic steel in fig. 3 and 4), the whole positioning device has no remanence, namely 1g of metal objects cannot be absorbed by six peripheral surfaces. The aforementioned 0 bit and 120 degree bit are the on bit and the off bit of the magnetic switch of the positioning device.
Of course, to achieve such a good remanence effect, it is necessary to consider the position between the upper and lower magnetic steels 100 and 200, for example, when the attraction forces of the upper and lower magnetic steels are both 50Kg, the effect is best when the distance (L in fig. 3) from the bottom surface of the upper magnetic steel 100 to the upper portion of the lower magnetic steel 200 is 1 mm. The magnetic force of the whole positioning device reaches more than 150kg, so that the effect that 1+1 is more than 2 is realized, and the increase of the magnetic force in geometric grade is realized.
As shown in fig. 2, in order to fix the magnetic steel 200, a slot for placing the magnetic steel 200 is further disposed on the rotating block 210; the rotation block 210 is fixed forward and backward by the fixing block 220 to be seated in the cylindrical hole 330. The fixing of the magnetic steel and the connection relation between the magnetic steel and the rotating handle are mature technologies, and are not described too much here.
As shown in fig. 3 and 4, when the switch is in the on position, the bottom of the metal shell 300 is magnetized, and the two groove surfaces 321 and 322 of the V-shaped groove 320 have magnetism and can be used as an adsorption surface for adsorbing a round pipe workpiece; or the bottom surfaces 341 and 341 of the case with the same magnetism are used as the adsorption surfaces of the metal workpiece with the plane surface, and how to select the metal workpiece can be flexibly determined according to the actual situation. Of course, two independent components different from the one-piece design in the present embodiment may be used as the two opposite sides of the workpiece suction surface, and in the case of two components, it is generally more reasonable to design the two workpieces as mirror images.
Although the distance between the upper and lower magnetic steels 100 and 200 is preferably 1mm when the magnetic force is 50kg, in practice, when the magnetic force becomes large, the distance L in the figure is kept as 1mm as much as possible in consideration of the possibility of rotation of the magnetic steel 200, and the magnetic force is lost when the distance is released. Therefore, this effect is sometimes achieved by controlling the thickness of the thinnest wall between the groove 310 and the cylindrical hole 330, for example, to 1 mm; the thickness of the thinnest wall between the V-shaped groove 320 and the cylindrical hole 330 is also sometimes controlled to be 1 mm.
As shown in fig. 7, a positioning device using the above positioning device is provided, which has a right-angle bracket 3, and 3 of the above magnetically switchable positioning devices 1 are disposed at two right-angle sides of the right-angle bracket 3, and are fixed on the right-angle bracket 3 by positioning connection plates 21, 22 and 23 respectively and positioning through mounting screws 4; one positioning device 3 which is positioned at a right angle and connected through the positioning connecting plate 22 can also relatively move along one right-angle side so as to better meet the actual positioning requirement; the displacement along one of the cathetuses in the figure is for example realized in the form of a positioning runner.
