Abstract

(57) [Summary] [Purpose] The purpose is to improve the electromagnetic force of an electromagnetic suction cup for application to hoists or for temporarily fixing a workpiece to a work table. [Structure] An intermediate plate is interposed between an electromagnetic coiler housed in a bottom plate for generating an electromagnetic force and a combined suction cup that directly contacts a processed product such as a processed product. [Effect] Since the intermediate plate is interposed, the magnetic area is increased, the magnetic force distribution can be expanded evenly, and the attraction force can be increased.

[0001]

[Industrial applications]

 This invention is a new type of electromagnetic suction cup, especially a single-sided combination suction cup, which is made by combining the copper of the suction cup and the iron material under high temperature and high pressure by the high-temperature hard-rod welding method, and especially the area of one magnetic field. It is devised to add an intermediate plate that can be expanded to increase the magnetic force three times that of the conventional technology and the pressure receiving force of 50%.

[Prior Art]

FIG. 4 is a three-dimensional exploded view showing an example of a suction cup structure of the prior art, and FIG. 5 is a combined assembly diagram of the same example. Regarding the constitution thereof, one cup-shaped block iron A1 or A1 in the suction cup A is shown. By grooving the concave-convex groove on the top, also grooving the concave space A ₂ on the bottom of A ₁ , and making another convex iron B with a convex tongue B ₁ and then B ₁ Through the space of A ₂ so that they can be brought into contact with each other up to the magnetic core C ₁ below. In addition, the insulating bronze D is sandwiched in the middle, and then tin or ▲ is added. Weld together by welding, the most complicated composition of them, and there are many difficulties in manufacturing.The most conventional technology is to use the low temperature brazing method. In this case, since pickling and tin or lead are mixed together before welding, the residue of acid and the impurities of lead and tin materials are also avoided. Come, also large changes in the chemical reaction, because you do not use the most high-temperature hardness ▲ rod ▼ welding method, does not mean tightness sucker tissue. In addition, Fig. 6 shows another conventional technology of the suction cup structure, or the size of the suction cup base is fixed, and its size cannot be adjusted. Also, the same old low temperature welding method is used to make it. It doesn't make sense if there are too many.

[0003]

[Problems to be solved by the device]

 However, the suction cup structure of this prior art is a low temperature welding processing method, and it is devised to rectify its drawbacks, and the problem is that the magnetic force is stronger and the bearing pressure is increased than in the prior art.

[0004]

[Means for Solving the Problems]

 In order to solve the above problems, this invention mainly comprises a combination suction cup, a bottom seat, an intermediate plate, and an electromagnetic coiler for a new type electromagnetic suction cup structure.

【Example】

 As shown in the drawings, the structure and function of the new type of electromagnetic suction cup will be described by way of examples.

Embodiment 1 FIG. 1 is a three-dimensional exploded view showing a constitutional example of the present invention. The combination suction cup 1, the base 2, the middle plate 3, and the electromagnetic coiler 4 constitute the artificial body of the invention. A plurality of convex and concave rectangular irons 11 and 12 and a piece of crimson copper 13 that can be insulated are assembled in a separable manner, and two side plates 14 are also provided on both sides to firmly fix the body. In order to make a combination, two sheet irons 121 are laid on both sides of the convex rectangular iron 11 of the combination sucker 1, the bottom tray 21 of the mold is opened in the base 2, and the electromagnetic coiler 4 is further installed. Invent the device so that it is placed on the bottom tray 21. Then, a magnetic core 22 is formed at the center of the base 1 again, and an intermediate plate 3 having a large area is also provided on the magnetic core 22, and the intermediate plate 3 is a rectangular conductive iron plate. It is conceived that the surrounding area is larger than the range of the magnetic core. After that, the convex length steel 11 and the middle plate 3 on which the convex length iron 11 is installed above are in close contact with each other, and the concave area is further reduced. Both sides of the rectangular steel 12 are made to hit the surface of the base 2 to make intimate contact.

Regarding the useful advantage of the structure, first, the copper bronze 13 sandwiched between the concave and convex rectangular irons 11 and 12 in the combination sucker 1 and the floor plate 14 below are all new and expensive. Since it is fused by a technical high-temperature hard-rod welding method, the internal structure can be precisely formed and the levelness is also high in the product made under the high-temperature or high-pressure welding method. The stability of the magnetic force is obtained, and the magnetic force that is about three times as strong as that of the conventional suction cup is created. From this, the combination suction cup 1 itself is not a fixed type, or the convex shape in it is long. Since the iron irons 11 and 12 and the red copper 13 sandwiched therebetween are all a single piece, and the compositional amount of each of them can be adjusted, the size of the combination sucker can be adjusted according to the customer's request. Because it is possible, it is also useful for commercial transactions, and it is necessary to confirm the effect of its practical use. .

Embodiment 2 As shown in FIG. 2 and FIG. 3, the middle plate 3 on the upper part of the magnetic core 22 is a specially designed one, and therefore, its magnetic area is increased and the combination suction cup 1 In order to expand the magnetic force distribution with each other on average, cooperation is expected to increase from 11 to 13 kg / m ² of the conventional suction cup to 17 to 19 kg / m ² . The function is remarkable.

[0009]

[Effect of the device]

According to the configuration described above, this invention is a high-temperature hard-rod welding method, and therefore a high-quality electromagnetic suction cup is manufactured. It can be freely adjusted, and in order to expand the magnetic field evenly, one large middle plate is specially devised and installed, and due to high temperature and high pressure welding, the tightness of the product Good, and if its magnetic strength is more than three times that of the suction cup of the prior art, it is conceivable that the receiving pressure will increase from 11 to 13 kg / m ^{2 of the} conventional type to 17 to 19 kg / m ² .

Further, regarding the present invention, in the application of the new type of electromagnetic suction cup, when carrying out general machining, instead of the holding object used before, for example, the pressure plate, the holding bolt, the pinch, the iron fitting, etc. Since this type of magnetic suction cup is used for holding work pieces, the magnetic suction force and pressure of the above-mentioned original electromagnetic suction cup is more than three times stronger than the conventional electromagnetic suction cup. You must make sure that the utility value that you use as your carry-on is maximized.
