Abstract
The invention provides a modularized quick-replacing electromagnetic clamp which comprises a pressing plate, a hollow base plate, magnetic conductive columns and a fixed plate. The base plate is fixed to a disk, a plurality of magnetic conductive columns with the consistent height are distributed on the disk, the fixed plate is provided with through holes for the magnetic conductive columns to penetrate and workpiece locating pins, the fixed plate is fixed to the base plate through a disk positioning pin, a workpiece is arranged above the fixed plate to come into contact with the magnetic conductive columns, and the pressing plate is arranged on the workpiece. The base plate and the fixed plate are made of non-magnetic conductive materials, and the magnetic conductive columns and the pressing plate are made of magnetic conductive materials. The magnetic conductive columns and the fixed plate are adopted, and magnetic force generated by the disk is scattered in a mode of replacing the surface with points to the plurality of magnetic conductive columns to perform conduction, the magnetic conductive columns can be reused, only the fixed plate and the pressing plate need to be replaced according to different workpieces, the fixed plate and the pressing plate are small in thickness, the base plate and the fixed plate are made of the ordinary non-magnetic conductive materials, and the cost is low. The disk positioning pin enables the fixed plate to be installed and positioned very quickly and easily, and the disk positioning pin is very convenient when different types of workpieces are switched.
Description
technical field [0001] The invention belongs to the technical field of clamps, and in particular relates to a modular quick-change electromagnetic clamp and an operating method thereof. Background technique [0002] At present, clamps for non-magnetic materials usually use cylinders and other methods. The machining object of the existing electromagnetic fixture method is mainly the processing of magnetically conductive materials. The electromagnetic clamping technology of non-magnetically conductive materials is applied late, and there are strict requirements for material thickness. The main source of clamping force is the air gap magnetic flux leakage. The effect is not obvious and the cost is high, so it is usually not selected by most processing enterprises. The current electromagnetic clamping process of non-magnetic materials is as follows: [0003] Such as figure 1 In the shown square magnetic pad scheme, a positioning pin and a square magnetic pad 2 are set on the ...
