Description

Miniature permanent magnet electric control disk

This creation is related to the device that uses magnetic force to clamp the workpiece to be processed, especially the miniature permanent magnet electric control disk.

Machining usually requires the use of clamps to fix the workpiece to the machine tool in order to smoothly perform various processing procedures. In addition to the common vise (VISE) or positioning and clamping kit (Clamping Kit) that uses direct mechanical force to clamp the fixed clamp fixture, there are also permanent magnet electro-controlled disks that generate magnetic force to attract the workpiece for processing.

Permanent magnet electric control disks mainly use the magnetic force between magnetic conductive parts to attract the parts to be processed. Generally, the distance between the magnetic conductive parts of permanent magnet electric control disks is relatively large, which is not suitable for precision processing of small parts to be processed. Moreover, the above-mentioned permanent magnet type electronically controlled magnetic disk has a relatively high magnetic amplitude and cannot be applied to the precision machining of thin workpieces, which may easily cause quality problems such as deformation.

The control method usually includes setting high magnetic strength aluminum corresponding to each magnetically permeable part 22. Nickel-cobalt permanent magnets, magnetic parts, and coils, use the current through the coil to generate magnetism to adjust the magnetic properties of the magnetic parts, and then match the permanent magnets to allow the adjacent magnetic conductive parts 22 to form a magnetic field to attract the workpiece to be processed , Or so that there is no magnetic field between the adjacent magnetic conductive parts 22 and the workpiece to be processed can no longer be adsorbed.

The permanent magnet type electrically controlled magnetic component 20 is arranged inside the main body 10, the plurality of magnetically conductive parts 22 are evenly distributed on the bearing surface 14, and the spacing between the plurality of magnetically conductive parts 22 is between 3mm and 8mm. In this preferred embodiment Each magnetically conductive part 22 may be a 35mm×35mm square as an example, the spacing between the magnetically conductive parts 22 is 7mm, and the magnetic width height is 15mm. Alternatively, each magnetically conductive portion 22 of the preferred embodiment may be another 20mm×20mm square as an example, the spacing between the magnetically conductive portions 22 is 4mm, and the magnetic width height is 10mm. In order to cope with the miniaturized size of the magnetic conductive part 22, the alnico grade of the aforementioned permanent magnets has been upgraded from LNG40 to LNG52, so that the coil can be driven by a smaller current to achieve a larger magnetic field, and the coil insulation grade is changed from E grade (120 degrees) C) Upgrade to level B (130 degrees C), which can effectively prevent the insulation layer structure damage caused by interlayer short circuit or temperature rise, and improve the coil yield.
