Description

Technical Field

[0001] The invention relates to the technical field of assembly equipment, and in particular to a light coreless electromagnetic device for liquid metal transmission and an assembly equipment thereof. Background Art

[0002] The existing electromagnetic transmission devices are all metal pipes for conveying liquids, which can only be used for room temperature or low temperature metal liquids, and cannot meet the needs of conveying high temperature liquids. In addition, in order to ensure magnetic efficiency, an iron core is added in the existing technology. Due to the high density and large size of the iron core material, the whole set of equipment is too heavy.

[0003] The current assembly method of the light coreless electromagnetic device for liquid metal transmission is often that the assemblers use the relevant assembly devices to sequentially install multiple assembly parts on the liquid conveying pipeline. Since the liquid conveying pipeline has a certain length, the assemblers cannot stand in a fixed position for assembly. The assemblers need to frequently move around at both ends of the liquid conveying pipeline for assembly, resulting in low assembly efficiency. In addition, the assembly parts need to be moved and positioned during the assembly process to ensure that the bolts on the assembly parts correspond to the screw holes to be assembled, so as to facilitate assembly.

[0004] To this end, we proposed a lightweight coreless electromagnetic device for liquid metal transmission and its assembly equipment. Summary of the invention

[0005] The purpose of the present invention is to solve the problems existing in the prior art and to propose a light coreless electromagnetic device for liquid metal transmission and an assembly device thereof.

[0014] Preferably, the assembly mechanism also includes a bottom plate fixedly connected to the side wall of the C-shaped block, a cylinder is fixedly mounted on the bottom plate, the cylinder is sealingly and slidably connected inside the cylinder, the bottom wall of the C-shaped block is fixedly connected to an arc box, the inside of the arc box is sealingly and slidably connected to a piston, the side wall of the push plate is fixedly connected to an arc rod, the other end of the arc rod passes through the inner wall of the arc box and is fixedly connected to the piston, the inner wall of the arc box is fixedly connected to a connecting pipe, and the other end of the connecting pipe is fixedly connected to the inner wall of the cylinder.

[0015] Preferably, the side wall of the L-shaped support plate is provided with a positioning mechanism for pushing and positioning the assembly, and the positioning mechanism includes a rectangular tube fixed to the side wall of the L-shaped support plate, and the inner wall of the rectangular tube is elastically connected to a rectangular slide through a plurality of second springs, and a push plate is installed on the other end of the rectangular slide for limited rotation.

[0016] Preferably, a nozzle is fixedly installed on the side wall of the hexagonal wrench tube, a cavity is opened on the inner wall of the rectangular tube, a slide is sealingly and slidably connected to the inner wall of the cavity, an extension rod is fixedly connected to the bottom end of the rectangular slide, the extension rod passes through the inner wall of the cavity and is fixedly connected to the slide, a first one-way tube and a second one-way tube are fixedly connected through the inner wall of the cavity, and the other end of the second one-way tube is fixedly connected to the nozzle.

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] 1. By setting structures such as cams, ball guides and push plates, the push plates and assembly surfaces are in contact and squeezed, and under the action of the ball guides and end cams, the push plates will drive the assembly to slide a distance on the side wall of the liquid conveying pipeline until the assembly cannot move, so that the bolts matched with the screw holes on the assembly and the screw holes on the liquid conveying pipeline are aligned;

[0022] 2. Then, when the non-convex part of the cam contacts the roller, by setting structures such as a torsion spring, a rectangular slide plate and a nozzle, under the elastic force of multiple second springs, the push plate still contacts the surface of the assembly for a period of time during this process, thereby playing a role in squeezing and stabilizing the assembly to prevent the assembly from sliding. At the same time, the slide plate squeezes the anti-rust oil in the cavity to the nozzle and sprays it into the position between the bolt and the screw hole, forming a protective layer on the bolts and screw holes of the assembled assembly to prevent corrosion of the metal surface and ensure the normal operation of the bolts and screw holes;

[0023] 3. Since the push plate rotates in the opposite direction at a certain angle, the push plate will drive the arc rod to move synchronously for a distance. By setting structures such as the arc box, the cylinder and the guide column, the cylinder drives the hexagonal wrench to rotate through the one-way bearing, and the hexagonal wrench tightens the bolt to complete the assembly of the assembly on the liquid conveying pipeline;

[0024] 4. The consumables used in the iron core in the prior art are high in density, too heavy, and difficult to install. The lightweight coreless iron core removes the weight of the iron core while ensuring the efficiency of molten metal transportation, making it more convenient to install and use. There is no iron core outside the coil, and only the winding process and superposition method of the coil are relied on to minimize the leakage magnetic field, ensuring the efficiency of the magnetic field, and reducing the cost of use and maintenance while meeting production needs;

[0025] 5. The circular pancake-type bidirectional winding coil has no internal metal winding tooling and will not be deformed due to high temperature. It can be used for molten metal at any temperature. The circular pancake-type bidirectional winding coil is wound with a hollow copper tube. Cooling water flows inside the copper tube to take away the heat generated by the coil. Both ends of the bidirectional winding coil are flat. Mica pads are used as insulation between adjacent coils, which can shorten the installation distance between adjacent coils and avoid magnetic field leakage. While ensuring the utilization efficiency of the magnetic field, the overall length of the electromagnetic device is shortened;

[0026] 6. The internal support layer of the coil blocks the molten metal when it leaks, preventing the coil from being damaged and providing internal support for the coil, thus improving the overall strength. The heat insulation layer uses a nano-insulation blanket, which contains nano-materials to achieve the maximum heat insulation effect. It is equipped with molten metal transmission pipelines of different materials. High-temperature liquid metal uses non-metallic high-temperature refractory materials and pipelines resistant to high-temperature molten metal flushing; other liquid metals can use non-magnetic austenitic stainless steel or metal pipelines made of special alloys. It is easy to disassemble and assemble, more versatile, and saves costs. BRIEF DESCRIPTION OF THE DRAWINGS

An electric telescopic fixture 13 is fixedly mounted on the inner side wall of the assembly box 11 .

[0055] In the present invention, end flanges 1 for connecting to external conveying pipelines are arranged at both ends of the light coreless electromagnetic device for liquid metal transmission; a flange connecting column 3 is arranged between the front and rear flanges for strengthening the overall structure; an end insulating pad 2 is arranged between the flange and the coil to prevent the coil from contacting the metal flange; a coil external reinforcement column 10 is arranged to support the coil outside the coil; a round cake-type bidirectional winding coil 4 is arranged, the coil part of the round cake-type bidirectional winding coil 4 is wound from the middle to the outside, and the joint part is at both ends of the round cake-type bidirectional winding coil 4, and both ends of the round cake-type bidirectional winding coil 4 are flat; an interlayer mica gasket 9 is arranged between the coils for insulation; a coil protective layer 5 is arranged to prevent high-temperature molten metal from leaking and damaging the coil; the round cake-type bidirectional winding coil 4 is provided with a coil internal support layer 6, which isolates the leakage of the molten metal and plays a role in strengthening the coil as a whole; a heat insulation layer 7 is arranged to isolate the temperature of the molten metal in the pipeline to prevent damage to the coil; a liquid conveying pipeline 8 is arranged, and the pipeline material can be selected according to the temperature of the molten metal.

[0056] The molten metal flows into the pipe from one side of the equipment, and flows to the other side under the action of electromagnetic force. It can flow in one direction, or it can change the direction of the current to achieve the reverse movement of the molten metal, that is, the interaction between the magnetic field and the current in the conductive fluid is used to make the fluid produce a pressure gradient under the action of electromagnetic force, thereby promoting the movement of the fluid. When the round pancake-type bidirectional winding coil 4 is energized, a magnetic field will be formed around it. This magnetic field interacts with the conductive fluid (such as molten metal) in the liquid conveying pipeline to generate an electromagnetic force. This electromagnetic force will push the fluid to flow in a certain direction, thereby realizing the pumping function, and realizing the effect of transporting the molten metal from one end to the other end in the horizontal direction, or from a low place to a high place in the vertical direction. It is suitable for molten metal under various temperature conditions, and its advantages are more prominent in high-temperature molten metal.

[0057] When using an assembly device for a light coreless electromagnetic device for liquid metal transmission for assembly, first fix one end of the liquid conveying pipeline 8 to the end flange 1, and then contact and clamp the end flange 1 and the electric telescopic clamp 13. The electric telescopic clamp 13 can drive the liquid conveying pipeline 8 to move horizontally for multiple times during the assembly process, and then the assembly parts are successively put on the liquid conveying pipeline 8 for sliding, so as to facilitate the subsequent fixing of screw holes at different positions on different assembly parts by bolts.

[0058] The assembly steps of the assembly parts are as follows: first, the assembly parts are sleeved on the side of the liquid conveying pipeline 8, and then pushed a certain distance along the axial direction of the liquid conveying pipeline 8. The assembly parts can only slide along the axial limit position on the side of the liquid conveying pipeline 8, thereby ensuring the accuracy of the subsequent assembly bolts. Then, the motor 16 is turned on, and the output end of the motor 16 drives the cam 17 to rotate, and the cam 17 drives the end face cam 48 fixedly connected to its side wall to rotate. Since the cam 17 and the roller 47 slide against each other, when the cam 17 rotates, the roller 47 will be driven to move through its raised part, and the roller 47 will drive the push plate 23 to rotate upward at a certain angle with the rotating shaft 22 as the center and overcome the elastic performance of the torsion spring 24. Then the push plate 23 will drive the L-shaped support plate 25 to rotate synchronously, so that the push plate 46 set on the L-shaped support plate 25 is in contact with the surface of the assembly parts. And extrusion is generated. Since the side parts of the ball guide rod 50 and the end face cam 48 slide against each other, under the action of the ball guide rod 50 and the end face cam 48, the ball guide rod 50 will drive the C-shaped block 20 and multiple sliders 54 to slide a certain distance along the axial direction of the liquid conveying pipeline 8 on the L-shaped plate 12 through the connecting plate 49, and then the C-shaped block 20 will drive the push plate 23 and the L-shaped support plate 25 to move synchronously through the rotating shaft 22, so that the rectangular cylinder 43, the rectangular slide plate 45 and the push plate 46 fixed on the L-shaped support plate 25 move synchronously, and then the push plate 46 will drive the assembly to slide a certain distance on the side wall of the liquid conveying pipeline 8 until the assembly cannot move. At this time, the push plate 46 and the surface of the assembly slide, and at this time the assembly has moved to the end of the stroke, so that the bolts on the assembly and the screw holes on the liquid conveying pipeline 8 are facing each other.

[0059] Then, when the non-raised portion of the cam 17 contacts the roller 47, under the pulling force of the torsion spring 24, the rotating shaft 22 will drive the push plate 23 to rotate in the opposite direction by a certain angle, and the push plate 46 will also move downward for a certain distance synchronously. Under the elastic force of multiple second springs 44, the push plate 46 will still be against the surface of the assembly for a period of time during this process, thereby playing a role in squeezing and stabilizing the assembly and preventing the assembly from sliding. At the same time, since the distance between the rectangular slide 45 and the rectangular tube 43 increases, the rectangular slide 45 will drive the slide 56 and the cavity 41 to slide in a relative sealing manner through the extension rod 15, and then the anti-rust oil inside the cavity 41 will be squeezed to the nozzle 55 through the slide 56 and sprayed into the position between the bolt and the screw hole, forming a protective layer on the bolts and screw holes of the assembled assembly to prevent corrosion of the metal surface and ensure the normal operation of the bolts and screw holes.

[0060] And because the push plate 23 rotates in the opposite direction by a certain angle, the push plate 23 will drive the arc rod 36 to move synchronously for a distance, so that the arc rod 36 drives the piston 37 to slide for a distance in a sealed manner inside the arc box 35. The arc box 35 is filled with hydraulic oil, so this part of the hydraulic oil will be squeezed into the cylinder 32 and push the cylinder 31 to slide outward for a distance. Since the side wall of the cylinder 31 is fixedly connected to the guide column 30, and the guide column 30 is slidably connected to the spiral groove 29, the cylinder 31 will rotate during the outward sliding process. At this time, the cylinder 31 drives the hexagonal wrench 34 to rotate through the one-way bearing 33, so that the hexagonal wrench 34 tightens the bolts to complete the assembly of the assembly on the liquid conveying pipeline 8.

[0061] After completing the assembly of the assembly part at the end of the liquid conveying pipeline 8 away from the assembler, the assembler only needs to install the other end of the assembly part at the original position. There is no need for the assembler to frequently move around at both ends of the liquid conveying pipeline 8 for assembly, thereby improving assembly efficiency.

[0062] 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 according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
