Description

Technical Field

[0001] The utility model relates to the technical field of electromagnets, in particular to a suction cup type electromagnet. Background Art

[0002] The electromagnetic chuck is a machine tool accessory product that uses the electromagnetic principle to generate magnetic force by energizing the internal coil, and then tightly sucks the workpiece in contact with the surface of the panel through the magnetic conductive panel. When the coil is powered off, the magnetic force disappears to achieve demagnetization and remove the workpiece.

[0003] At present, when the suction cup electromagnet is working, it will generate more heat when the electromagnet is powered on and works for a long time. It needs to be cooled to ensure its service life. When adsorbing the workpiece, it can only be adsorbed on the surface of the workpiece, and it cannot ensure that the center of the workpiece and the center of the electromagnet are on the same vertical line, which is not conducive to the use and processing of the workpiece. For this reason, we designed a suction cup electromagnet to solve the above problems. Utility Model Content

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0011] Preferably, the clamping plate extends to the bottom of the shell, and the clamping plate is inclinedly arranged close to a side wall of one end of the shell.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. This suction cup electromagnet places the electromagnet body on the surface of the workpiece that needs to be adsorbed.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-Figure 6 A suction cup type electromagnet comprises a shell 1, an electromagnet body 2, a filling resin 3 and a wire 7, the wire 7 is connected to the electromagnet body 2, and controls the electromagnet body 2 to be powered on and off, the upper end of the shell 1 is connected to a heat dissipation cover 5, the heat dissipation cover 5 is mounted on the shell 1 by screws 4, and is easy to disassemble and install, a plurality of heat dissipation holes 6 are penetrated and opened on the heat dissipation cover 5, and the setting of the heat dissipation holes 6 can dissipate the electromagnet body 2 in the shell 1, and dustproof nets are installed in the plurality of heat dissipation holes 6, and the setting of the dustproof nets can reduce the dust from entering the shell 1 through the heat dissipation holes 6, and the wire 7 penetrates the heat dissipation cover 5 and extends to the top thereof;

[0025] The side wall of the housing 1 is fixedly connected with an annular mounting plate 8, which can be installed on the housing 1 by mounting screws, so that the annular mounting plate 8 can be easily disassembled and installed. The side wall sliding sleeve of the housing 1 is provided with an annular connecting plate 9, and the annular connecting plate 9 and the annular mounting plate 8 are connected by multiple locking components. The locking component includes a U-shaped plate 10 engaged between the annular mounting plate 8 and the annular connecting plate 9. The U-shaped plate 10 can connect the annular connecting plate 9 to the bottom of the annular mounting plate 8 so that the annular connecting plate 9 cannot move up and down. The U-shaped plate 10 and the annular mounting plate 8 and the annular connecting plate 9 are penetrated with through holes located on the same vertical line, and a T-shaped plug rod 11 is slidably connected in multiple through holes. The T-shaped plug rod 11 can limit the annular connecting plate 9 so that the annular connecting plate 9 cannot move relative to the annular mounting plate 8. A plurality of first springs 12 are connected between the upper ends of the T-shaped plug rod 11 and the U-shaped plate 10. The first spring 12 is a tension spring, which can pull the T-shaped plug rod 11 downward in a natural state, so that the T-shaped plug rod 11 cooperates with the U-shaped plate 10 to stably fix the annular connecting plate 9 on the annular mounting plate 8;

[0026] The annular array of the side wall of the annular connecting plate 9 is provided with multiple clamping components, and the clamping components include a mounting groove 13 opened on the side wall of the annular connecting plate 9, and a connecting rod 14 extending to the outside of the annular connecting plate 9 is slidably connected in the mounting groove 13, and multiple second springs 15 are connected between the connecting rod 14 and the inner side wall of the mounting groove 13. The second spring 15 is a tension spring, which can pull the connecting rod 14 into the mounting groove 13 in a natural state. The side wall of the connecting rod 14 is fixedly connected with a clamping plate 16, and the clamping plate 16 extends to the bottom of the shell 1. The multiple clamping plates 16 work together to clamp and fix the magnetic workpiece, and the multiple clamping plates 16 can push the magnetic workpiece to move and automatically center the magnetic workpiece, so that the center of the magnetic workpiece and the center of the shell 1 are located on the same vertical line, and the clamping plate 16 is inclined near the side wall of one end of the shell 1 to facilitate the magnetic workpiece to be clamped between the multiple clamping plates 16.

[0027] The functional principle of the utility model can be explained through the following operation modes:

[0028] In the utility model, when the suction cup type electromagnet is in use, the user holds the shell 1 and places the electromagnet body 2 on the surface of the workpiece to be adsorbed. Since the bottom of the inner side wall of the clamping plate 16 is inclined, when the clamping plate 16 abuts against the upper end of the workpiece, the workpiece can push the multiple clamping plates 16 away from each other first, until the workpiece moves between the multiple clamping plates 16 and abuts against the inner side wall of the clamping plate 16, and the second spring 15 pulls the connecting rod 14 to move into the installation groove 13, so that the multiple clamping plates 16 work together to push the workpiece to move, so that the center of the workpiece and the center of the shell 1 are located on the same vertical line, and the electromagnet body 2 is energized to make the electromagnet body 2 adsorb the workpiece;

[0029] The electromagnet body 2 generates a lot of heat when working. The heat is dissipated through the heat dissipation holes 6 to reduce the heat of the electromagnet body 2. The provision of the dustproof net can reduce the dust from entering the housing 1 through the heat dissipation holes 6, thereby ensuring the service life of the electromagnet body 2.

[0030] When different clamping assemblies are needed for automatic centering when adsorbing workpieces of different sizes, the T-shaped rod 11 is pulled upward to move it out from the through openings in the annular mounting plate 8 and the annular connecting plate 9, so that the U-shaped plate 10 can be removed from the annular mounting plate 8 and the annular connecting plate 9, and then the annular connecting plate 9 can be removed from the outer shell 1, and the replaced annular connecting plate 9 is sleeved on the outer shell 1, and the T-shaped rod 11 is pulled upward to sleeve the U-shaped plate 10 on the annular mounting plate 8 and the annular connecting plate 9, so that the T-shaped rod 11 passes through the through openings on the U-shaped plate 10, the annular mounting plate 8, and the annular connecting plate 9. The first spring 12 can pull the T-shaped rod 11 downward to firmly fix the U-shaped plate 10. The operation is simple and the replacement is completed.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
