Description

Technical Field

[0001] The invention relates to the field of electromagnetic transmission, and in particular to an outer iron core type electromagnetic device for liquid metal transmission and an assembly device thereof. Background Art

[0002] Although the iron core of the existing electromagnetic transmission device is large in size, it cannot completely wrap the coil, resulting in large-area magnetic leakage, reducing the efficiency of the magnetic field, resulting in reduced efficiency in conveying liquids. In addition, the original coil structure needs to be wound on the tooling, and the winding tooling and the coil are installed inside the iron core together. This structure determines that high-temperature molten liquid cannot be conveyed, because the high-temperature molten liquid causes the metal tooling inside the coil to deform, thereby affecting the normal use of the coil. The existing electromagnetic transmission device conveys liquids in metal pipes, which can only be used for room temperature or low-temperature metal liquids and cannot meet the transportation needs of high-temperature liquids.

[0003] In this regard, we designed an electromagnetic device that can meet the needs of high-temperature liquid transportation. The electromagnetic device uses a round pancake-type bidirectional winding coil without internal metal winding tooling. It can supply molten metal at any temperature. At the same time, mica gaskets are used as insulation between adjacent coils to shorten the installation distance between adjacent coils and avoid magnetic field leakage. While ensuring the efficiency of magnetic field utilization, the overall length of the electromagnetic device is shortened. However, when installing mica gaskets and coils, the existing assembly equipment can only provide a loading function, and it is impossible to tighten the installed mica gaskets and coils. Therefore, in the current installation process, the operator still needs to manually tighten the installed mica gaskets or coils, that is, automatic loading cannot be achieved. For this reason, we need to redesign an assembly device for this electromagnetic device. Summary of the invention

[0004] Based on this, it is necessary to provide an external iron core type electromagnetic device and assembly equipment for liquid metal transmission in response to the existing technical problems.

The arc-shaped iron core has a stronger wrapping property for the internal winding coil, and the tight fit makes the magnetic efficiency higher, and increases the supporting strength of the outside of the winding coil, which is convenient for installation and can prevent the leakage of the induced magnetic field of the winding coil to the greatest extent. At the same time, the circular bidirectional winding coil is wound with a hollow copper tube, and cooling water passes through the copper tube to take away the heat generated by the winding coil. Mica gaskets are used as insulation between adjacent winding coils, which can shorten the installation distance between adjacent coils, avoid the leakage of the magnetic field, and shorten the overall length of the electromagnetic device while ensuring the utilization efficiency of the magnetic field.

[0022] Second: The device is provided with a rubber plug to buckle the winding coil and the mica gasket during the installation process, so as to prevent the winding coil and the mica gasket from moving during the alternating installation process, thereby preventing the magnetic field from leaking during the subsequent work;

[0023] Thirdly, the device uses a tightening mechanism to tighten the installed winding coil and mica gasket, ensuring that the mica gasket can be automatically loaded with the winding coil. At the same time, the four positioning plates and two rubber plugs work alternately to keep the winding coil and the mica gasket tightly combined at all times during the assembly process, preventing the misalignment of the two from affecting the normal operation of the magnetic field.

[0024] Fourthly: the device uses a cylinder to ensure that the winding coils and mica gaskets are always kept tightly against each other during the staggered installation process, and when the two rubber rods are reset from the retracted state to the initial state, the positioning plate can complete the handover work with the rubber rods to prevent affecting the subsequent installation of the winding coils or mica gaskets.

[0040] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0041] refer to Figures 1 to 13, an outer iron core type electromagnetic device for liquid metal transmission, characterized in that it includes: an insulation layer 7, a coil protection layer 6, two end flanges 1, four groups of flange connection columns 2, a plurality of outer iron cores 3, two insulating pads 4 and a plurality of winding coils 5, the end flange 1 is used to connect a liquid delivery pipeline 8, the four groups of flange connection columns 2 are arranged on the side close to the two end flanges 1, a plurality of outer iron cores 3 are arranged in an array at equal intervals along the flange connection columns 2, a plurality of winding coils 5 are arranged in an array at equal intervals on the inner side of the plurality of outer iron cores 3, two adjacent winding coils 5 are insulated by mica gaskets 51, the two insulating pads 4 are respectively coaxially fixedly connected to the side close to the two end flanges 1, the insulating pads 4 are fixedly connected to the ends of the flange connection columns 2, the coil protection layer 6 is fixedly connected to the inner sides of the plurality of winding coils 5, and the insulation layer 7 is fixedly connected to the inner side of the coil protection layer 6.

[0042] The two end flanges 1 in the electromagnetic device are used to connect the external liquid delivery pipeline 8, and the several outer iron cores 3 arranged along the axis of the end flange connection column 2 are made of several silicon steel sheets. The outer iron core 3 of this structure is simple to make, and the overall structure has higher strength. The arc-shaped outer iron core 2 has a stronger wrapping property for the internal winding coil 5. The tight fit makes the magnetic efficiency higher and increases the external support strength of the winding coil 5. It is convenient for installation and can prevent the leakage of the induced magnetic field of the winding coil 5 to the greatest extent. At the same time, the coil protection layer 6 is used to prevent the high-temperature metal solution from damaging the winding coil 5, and the heat insulation layer 7 is used to isolate the temperature in the liquid delivery pipeline 8. The material of the liquid delivery pipeline 8 can be selected according to the temperature of the metal solution.

[0043] The winding coil 5 adopts a double helix structure (generally, the winding coil 5 has an inlet after winding, and the double helix structure ensures that the outlets of the winding coil 5 are all on the outside of the winding coil 5, and the outlet ends of the winding coil 5 are separated in the gap of the outer iron core 3 to avoid magnetic leakage to the greatest extent). There is no internal metal winding tooling, and it will not be deformed due to high temperature. It can be used for metal melt at any temperature. The winding coil 5 is wound with a hollow copper tube. Cooling water passes through the copper tube to take away the heat generated by the winding coil 5. Mica gaskets 51 are used as insulation between two adjacent winding coils 5, which can shorten the installation distance between the two adjacent winding coils 5, avoid magnetic field leakage, and shorten the overall length of the electromagnetic device while ensuring the utilization efficiency of the magnetic field.

[0044] An assembly device for an outer iron core type electromagnetic device for liquid metal transmission, comprising:

[0045] Loading robot arm 61;

[0046] A base 71 is arranged beside the loading robot arm 61;

[0047] The elastic anti-slip assembly 81 is connected to the base 71 and includes two screw seats 17 and two clamping mechanisms 18. The two screw seats 17 are respectively slidably connected to the upper end of the base 71 (such as Fig.11 As shown), two clamping mechanisms 18 are respectively connected to two screw seats 17, each clamping mechanism 18 includes a positioning frame 19 and a rubber plug 28, the positioning frame 19 is fixedly connected to the upper end of the screw seat 17, and the rubber plug 28 is slidably arranged at the lower part of the positioning frame 19 and presses the installed mica gasket 51 or the winding coil 5;

[0048] The tightening mechanism 37 is arranged at the upper end of the base 71, and includes a cylinder 40 and four positioning plates 43. The cylinder 40 is arranged on the side close to the two positioning frames 19, and the four positioning plates 43 are respectively arranged on one side of the output end of the cylinder 40. The four positioning plates 43 tighten the installed mica gasket 51 or the winding coil 5.

[0049] When the device is in operation, as the assembled connecting column 5 and the outer core 2 are moved to the upper end of the base 71, the elastic anti-slip assembly 81 is activated and drives the two screw seats 17 set at the upper end of the base 71 to move. After the two screw seats 17 move, they will drive the corresponding positioning frame 19 to move. When the positioning frame 19 moves, it will first drive the corresponding rubber plug rod 28 to buckle on the corresponding winding coil 5 and mica gasket 51, and the new mica gasket 51 and the winding coil 5 are loaded from top to bottom by the loading robot arm 61. After being placed on the upper end of the outer core 2, when the new mica gasket 51 and the winding coil 5 press down the rubber plug 28, the rubber plug 28 will retract in the direction close to the positioning frame 19, avoiding the mica gasket 51 and the winding coil 5 being installed. At this time, the clamping mechanism 37 is started and drives the positioning plate 43 to press against the mica gasket 51 and the winding coil 5 through the cylinder 40, preventing the mica gasket 51 and the winding coil 5 from moving due to loss of clamping force after the rubber plug 28 retracts.

[0050] In order to facilitate the retracted rubber plug 28 to move to the installation position of the next winding coil 5 or mica gasket 51, the elastic anti-slip assembly 81 will continue to drive the two screw seats 17 to move, and the screw seats 17 will drive the positioning frame 19 to move after moving, and the output end of the cylinder 40 will extend when the positioning frame 19 moves, ensuring that the four positioning plates 43 can press against the installed winding coil 5 and mica gasket 51 until the two rubber plugs 28 move again to the side of the installed winding coil 5 or mica gasket 51. At this time, the two rubber plugs 28 rebound to the side of the winding coil 5 and mica gasket 51 under the action of the clamping mechanism 18 and press them tightly, and the cylinder 40 will drive the positioning plate 43 to move in the direction close to the cylinder 40. After the four positioning plates 43 leave the installed mica gasket 51 or winding coil 5, the loading robot arm 61 loads the next mica gasket 51 or winding coil 5 to be installed.

[0051] In order to drive the two screw seats 17 to move, the following features are also specifically provided:

[0052] The elastic anti-slip assembly 81 also includes a dual-axis motor 9, two first bevel gears 10, two bevel gear racks 11, two second bevel gears 12, two first pulleys 13, two second pulleys 14, two screw sleeves 15 and two screws 16. The dual-axis motor 9 is fixedly connected to the base 71 (refer to Fig.10 ), two bevel gear racks 11 are symmetrically arranged at both ends of the dual-axis motor 9 and are fixedly connected to the base 71, two first bevel teeth 10 are respectively rotatably connected to the two bevel gear racks 11, and the two first bevel teeth 10 are respectively coaxially fixedly connected to the two output ends of the dual-axis motor 9, two second bevel teeth 12 are respectively rotatably connected to the two bevel gear racks 11 and mesh with the two first bevel teeth 10, two first pulleys 13 are respectively coaxially fixedly connected to the two second bevel teeth 12, two second pulleys 14 are respectively rotatably arranged above the two first pulleys 13 and are connected to the two first pulleys 13 through belts, and two screw sleeves 15 are respectively fixedly connected to the two screw seats 17 (reference Fig.11 ), the two second pulleys 14 are respectively coaxially fixedly connected with one end of the two screws 16, and the two screws 16 are respectively rotatably connected with the base 71 and threadedly connected with the corresponding screw sleeves 15. After the dual-axis motor 9 is started, the dual-axis motor 9 will drive the two second bevel teeth 12 to rotate through the two first bevel teeth 10. In this process, the two output ends of the dual-axis motor 9 have opposite directions and the same output power, thereby avoiding the two second bevel teeth 12 from rotating in opposite directions. When the second bevel teeth 12 rotate, the second bevel teeth 12 will drive the two second pulleys 14 to rotate through the two first pulleys 13, and the two second pulleys 14 will drive the two screws 16 to rotate. After the two screws 16 rotate, they will drive the screw seat 17 to move through the screw sleeve 15.

[0053] In order to facilitate the rubber rod 28 to abut against the winding coil 5 and the mica gasket 51, the rubber rod 28 will move away from the winding coil 5 and the mica gasket 51, and the following features are specifically provided:

[0054] The upper side of the end of the rubber rod 28 away from the screw seat 17 is formed with an inclined surface 29 (refer to Figure 6 When the winding coil 5 and the mica gasket 51 abut against the inclined surface 29 of the rubber plug 28, the winding coil 5 and the mica gasket 51 will apply a horizontal thrust to the rubber plug 28 through the inclined surface 29 of the rubber plug 28, so that the rubber plug 28 can move away from the winding coil 5 and the mica gasket 51.

[0055] In order to realize the elastic movement of the rubber plug 28, the following features are also specifically provided:

[0056] The clamping mechanism 18 further includes a positioning socket 34 and a return spring 36. The positioning socket 34 is fixedly connected to the lower portion of the positioning frame 19 (refer to Fig.13 ), the return spring 36 is arranged inside the positioning socket 34, one end of the return spring 36 is fixedly connected to the positioning socket 34, and the other end is fixedly connected to the rubber plug 28. When the rubber plug 28 moves, the rubber plug 28 will drive the return spring 36 to be compressed, so as to prepare for the subsequent reset of the rubber plug 28.

[0057] In order to achieve the retention of the rubber rod 28 after it moves, the following features are also specifically provided:

[0058] The elastic anti-slip assembly 81 also includes a limit pin 31 and a limit spring 33. The rubber plug 28 is formed with a limit hole 30 at one end close to the return spring 36, and a positioning through hole 35 is formed at the upper end of the positioning socket 34 (refer to Fig.13 ), the limit pin 31 is slidably connected with the limit hole 30, the limit spring 33 is arranged inside the limit hole 30, the upper end of the limit spring 33 is fixedly connected with the limit pin 31, and the lower end is fixedly connected with the rubber plug 28 through the pad, the limit pin 31 passes through the positioning through hole 35 when the rubber plug 28 pushes the reset spring 36 to compress, and the limit pin 31 is formed with an arc surface 32 on the side away from the reset spring 36. When the rubber plug 28 moves, the rubber plug 28 will drive the limit pin 31 to move until the limit pin 31 extends upward from the positioning through hole 35. When the limit pin 31 extends upward, the limit spring 33 provides power for it, and the limit pin 31 will interfere with the positioning through hole 35 after it extends, and at this time the reset spring 36 cannot push the rubber plug 28 to reset itself.

[0059] In order to provide a detailed supplement to the structure of the clamping mechanism 18, the following features are also specifically provided:

[0060] The clamping mechanism 18 also includes a positioning motor 20, a first gear 21, a second gear 22, a reciprocating wire sleeve 23 and a reciprocating wire rod 24. The positioning motor 20 is fixedly connected to the side wall of the positioning frame 19 (refer to Fig.13 ), the first gear 21 is coaxially fixedly connected to the output end of the positioning motor 20, the second gear 22 is rotatably connected to the upper end of the positioning frame 19 and meshes with the first gear 21, the reciprocating wire sleeve 23 is rotatably connected to the upper end of the positioning frame 19 and coaxially fixedly connected to the second gear 22, and the reciprocating screw rod 24 is threadedly connected to the reciprocating wire sleeve 23. After the positioning motor 20 is started, the positioning motor 20 will drive the second gear 22 to rotate through the first gear 21, and the second gear 22 will drive the reciprocating screw rod 24 to reciprocate in the vertical direction through the reciprocating wire sleeve 23. The specific limiting process of the reciprocating screw rod 24 will be explained in detail later.

[0061] In order to limit the movement of the reciprocating screw rod 24, the following features are also specifically provided:

[0062] The clamping mechanism 18 also includes a reciprocating slide 25, two positioning sleeves 26 and two positioning rods 27. The reciprocating slide 25 is fixedly connected to the lower end of the reciprocating screw 24. The two positioning rods 27 are respectively fixedly connected to the two ends of the upper side of the reciprocating slide 25. One end of the two positioning sleeves 26 is respectively slidably connected to the two positioning rods 27, and the other end is respectively fixedly connected to the positioning frame 19. When the reciprocating screw 24 moves, the reciprocating screw 24 will drive the reciprocating slide 25 to move. When the reciprocating slide 25 moves downward, it will push the limit pin 31 to move downward. In this process, since the arc surface 32 of the limit pin 31 will abut against the inner wall of the positioning through hole 35, the reset spring 36 will directly push the rubber plug 28 to move to the initial position.

[0063] When the reciprocating slide 25 moves, the reciprocating slide 25 is limited by the relatively movable positioning sleeve 26 and the positioning rod 27, thereby preventing the reciprocating screw rod 24 from being unable to drive the reciprocating slide 25 to move.

[0064] In order to supplement the specific structure of the pressing mechanism 37, the following features are also specifically provided:

[0065] The abutting mechanism 37 further includes a transfer plate 39, a abutting bracket 41, two curved plates 42 and two transfer racks 38. The two transfer racks 38 are respectively fixedly connected to the two positioning racks 19 (refer to Figure 5 ), the two ends of the transfer plate 39 are respectively fixedly connected to the two transfer racks 38, the cylinder 40 is fixedly connected to the middle of the transfer plate 39, the abutting bracket 41 is fixedly connected to the output end of the cylinder 40, the two curved plates 42 are respectively fixedly connected to the two ends of the abutting bracket 41, and each curved plate 42 is respectively fixedly connected to two positioning plates 43 on one side away from the cylinder 40. When the screw seat 17 moves, the screw seat 17 will drive the transfer plate 39 to move through the transfer rack 38, and the transfer plate 39 will drive the cylinder 40 to move, that is, to ensure that the cylinder 40 will move with the movement of the screw seat 17.

[0066] After the cylinder 40 is started, the cylinder 40 will drive the two curved plates 42 to move by pressing against the bracket 41 . After the two curved plates 42 move, they will drive the four positioning plates 43 to press against the winding coil 5 or the mica gasket 51 .

[0067] In order to reduce the friction between the curved plate 42 and the winding coil 5 or the mica gasket 51, the following features are also specifically provided:

[0068] The pressing mechanism 37 further includes a plurality of positioning balls 44. The side of each positioning plate 43 away from the curved plate 42 is rotatably connected to the plurality of positioning balls 44 (see Figure 8When the positioning plate 43 drives the positioning balls 44 to press against the winding coil 5 and the mica gasket 51, the positioning balls 44 can reduce the friction between the curved plate 42 and the winding coil 5 or the mica gasket 51 to prevent the installation of the winding coil 5 and the mica gasket 51 from being affected.

[0069] The working principle of this device is that when the device is in operation, as the assembled connecting column 5 and the outer iron core 2 are moved to the upper end of the base 71, the dual-axis motor 9 starts and drives the two screw seats 17 set at the upper end of the base 71 to move. After the two screw seats 17 move, they will drive the corresponding positioning frame 19 to move. When the positioning frame 19 moves, it will first drive the corresponding rubber insertion rod 28 to buckle on the side ends of the corresponding winding coil 5 and mica gasket 51. At this time, the corresponding winding coil 5 and mica gasket 51 will be simulated by the two rubber insertion rods 28. Manual buckling.

[0070] While the new mica gasket 51 and the winding coil 5 are being placed from top to bottom on the upper end of the outer iron core 2 by the loading machine arm 61, when the new mica gasket 51 and the winding coil 5 press down the rubber insert 28, the rubber insert 28 will retract in the direction close to the positioning frame 19, avoiding the mica gasket 51 and the winding coil 5 being installed. During this process, the reset spring 36 will be compressed until the limit pin 31 extends upward from the positioning hole 35. When the limit pin 31 extends upward, the limit spring 33 provides power for it, and the limit pin 31 will interfere with the positioning hole 35 after being extended. At this time, the reset spring 36 cannot push the rubber insert 28 to reset itself.

[0071] At this time, the air cylinder 40 will start to drive the positioning plate 43 to press against the mica gasket 51 and the winding coil 5 to prevent the mica gasket 51 and the winding coil 5 from moving due to loss of pressing force after the rubber plug 28 retracts. When the positioning plate 43 drives a number of positioning balls 44 to press against the corresponding mica gasket 51 or the winding coil 5, the loading robot arm 61 releases the mica gasket 51 or the winding coil 5.

[0072] In order to facilitate the retracted rubber plug 28 to move to the installation position of the next winding coil 5 or mica gasket 51, the dual-axis motor 9 will continue to drive the two screw seats 17 to move when it is started. The movement of the screw seat 17 will drive the positioning frame 19 to move, and the output end of the cylinder 40 will extend when the positioning frame 19 moves, ensuring that the four positioning plates 43 can press against the installed winding coil 5 and mica gasket 51 until the two rubber plugs 28 move again to the side of the installed winding coil 5 or mica gasket 51. At this time, the two rubber plugs 28 rebound to the side of the winding coil 5 and mica gasket 51 under the action of the clamping mechanism 18 and press them tightly, and the cylinder 40 will drive the positioning plate 43 to move in the direction close to the cylinder 40. After the four positioning plates 43 leave the installed mica gasket 51 or winding coil 5, the loading robot arm 61 loads the next mica gasket 51 or winding coil 5 to be installed.

[0073] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
