Magnetic chuck is a kind of electromagnetic induction, by making the internal electrical magnetic coil, a magnetic panel, will contact tightly to absorb on the surface of the workpiece in the panel, power through the coil, magnetic disappear achieve demagnetization, remove the workpiece and the principle of the production of a machine tool accessory products.
Electromagnetic sucker is a kind of electromagnetic clamping device, which is used to fix the workpiece by the suction of the sucker after the electromagnetic coil is energized.
Electromagnetic sucker is made up of iron core, coil, panel and bracket.
The electromagnet composed of coil and iron core is the main part of electromagnetic sucker.
Electromagnetic suckers are different from design methods or materials, and are constantly evolving and improving.
Electromagnetic suckers are initially used in grinding machines instead of splints and bolts to fix the grinding workpieces, which are relatively simple and can only be fixed in a flat plate.
This is the traditional electromagnetic sucker, its application has great limitation.
With the development of the industry, the enterprise demand for electromagnetic tools more and more big, the demands more and more is also high, encourage people to make a series of improvements on magnetic chuck, can meet the needs of production.
The shape and distribution of polar cores vary according to the workpiece.
The structure of the common electromagnetic sucker is rectangular, circular, etc. The rectangular magnetic pole is divided into two types: vertical and horizontal.
Rectangular magnetic pole longitudinal arrangement, suitable for fixed and larger processing workpieces;
The rectangular magnetic poles are arranged horizontally, which is suitable for machining small machining parts.
Circular suction cups are suitable for fixed ring type workpieces or complex workpieces.
The main characteristics of ordinary electromagnetic sucker are: the magnetic force line is not concentrated on the surface of the disk, the electromagnetic force is not concentrated, the magnetic force is relatively small on the unit area;
The direction of magnetic force is perpendicular to the surface of the sucker, it is difficult to change, and only one magnetic force can be produced for the workpiece of the same suction area.
The force of the magnetic force on the workpiece is limited to the contact surface of the workpiece and the sucker.
Therefore, there are disadvantages such as low positioning accuracy, small clamping force, narrow range of use and low production efficiency.
