Detailed Description
The present invention will be described in further detail with reference to the following embodiments and the accompanying drawings.
An electromagnetic clamp as shown in figure 1, characterized in that: including electromagnet 1, a plurality of electromagnetism guide pillar 3 and positioner 2 are placed to electromagnet 1 upper surface, be provided with the electromagnetism backplate 4 of fixed positioner 2 and electromagnetism guide pillar 3 on the electromagnet 1, positioner 2 and electromagnetism guide pillar 3's upper portion stretch out on the electromagnetism backplate 4 and be used for location and support the work piece, the top of electromagnetism backplate 4 is provided with and is used for pressing the work piece electromagnetism apron 6 on electromagnetism guide pillar 3, it dodges hole 8 and opposite sex and dodges hole 7 to have the processing on the electromagnetism apron 6.
The electromagnetic chuck 1 provides magnetic force for the clamp, can be controlled to be powered on or powered off through a button or machine tool code, is a non-standard special part, and is provided with 6-M10 threaded holes and
and the pin holes are used for facilitating the installation of other subsequent parts, and the square grid size is 18x18 mm.
Principle of electromagnetic chuck: the electromagnetic chuck is a machine tool accessory product produced by the principle that an internal coil is electrified to generate magnetic force, the magnetic force passes through a magnetic conduction panel to attract a workpiece contacted on the surface of the panel, the coil is powered off, the magnetic force disappears to realize demagnetization, and the workpiece is taken down.
The electromagnetic chuck has the characteristics that:
1. suction force of the sucker: the electric control sucker has super strong suction force which can reach 16KG/cm2 at most, and the magnetic force is distributed uniformly.
2. And (3) machining precision: the continuous operation does not generate heat, and the parts are prevented from being deformed by heat.
3. The service performance is as follows: the electric control powerful suction cup can be continuously used, continuously works for more than 20 hours every day, does not have any fault, and does not need to be maintained.
4. The operation efficiency is simple, one button or code is used, the clamping and the releasing of the parts can be completed within 0.3 second, and the production efficiency can be greatly improved.
The electromagnetic guide posts 3 are uniformly arranged on the surface of the electromagnetic chuck 1 according to the structure of a workpiece to be clamped, and the electromagnetic guide posts 3 are made of a magnetic conductive material. The electromagnetic guide posts 3 provide support for the parts, play a role in supporting, generally need to select a material with better magnetic permeability, such as industrial pure iron or low-carbon steel, the electromagnetic guide posts need to be uniformly arranged on the surface of the electromagnetic chuck, for thin-wall parts, the more the electromagnetic guide posts are, the better the electromagnetic guide posts are theoretically, and in the arrangement process, the interference parts of the parts and the clearance parts of the electromagnetic squares need to be considered.
The positioning device 2 is a positioning pin or an end face limiting block. Positioning pins: the part is positioned, a group of round pins and diamond pins which are arranged along the opposite angles of a workpiece to be clamped are usually selected for limiting, and fixing pins are generally adopted (generally, the clamp is used for thin-wall parts).
For parts without positioning holes on the product, the appearance limitation can be adopted, and end face limiting blocks are arranged around the parts for fixation.
The electromagnetic cover plate is used for clamping workpieces, parts needing to be machined are hollowed out and avoided, other parts are used for clamping, the electromagnetic cover plate 6 is provided with a positioning hole 9 matched with the positioning pin, the guard plate is also required to be provided with two pin holes consistent with the positioning hole of a product, and therefore the electromagnetic cover plate can be placed accurately, the electromagnetic cover plate is prevented from being placed partially, and the parts are pressed askew.
The electromagnetic protection plate is used for fixing the magnetic conduction column and the positioning pin, the thickness of the electromagnetic protection plate is 3-5mm, the electromagnetic protection plate 4 is provided with the limiting holes for positioning the positioning pin 2 and the electromagnetic guide column 3, after the magnetic conduction column and the positioning pin are fixed, the electromagnetic protection plate is fixed on the electromagnetic chuck and locked by using an M10 screw, and the installation hole positions of the protection plate and the electromagnetic chuck are matched.
The technical solutions provided by the embodiments of the present invention are described in detail above, and the principles and embodiments of the present invention are explained herein by using specific examples, and the descriptions of the embodiments are only used to help understanding the principles of the embodiments of the present invention; meanwhile, for a person skilled in the art, according to the embodiments of the present invention, there may be variations in the specific implementation manners and application ranges, and in summary, the content of the present description should not be construed as a limitation to the present invention.
