Description

Technical Field

[0001] This utility model relates to the field of electromagnetic induction heating, and in particular to a device for positioning coil assemblies. Background Technology

[0002] Electromagnetic induction heating, or simply induction heating, is a method of heating conductive materials such as metals, primarily used for metal hot working, heat treatment, welding, and melting. Induction heating utilizes electromagnetic induction to generate an electric current within the material being heated, relying on the energy of these eddy currents to achieve the heating purpose. The basic components of an induction heating system include an induction coil, an AC power supply, and the workpiece. Depending on the object being heated, the coil can be made in different shapes and spacings, which greatly affects the temperature rise of the workpiece.

[0003] Currently, after the electromagnetic coil is wound as a whole, the coil is prone to displacement and misalignment, which can cause electromagnetic field failure or affect product power. There is a lack of an effective tool for quickly fixing the electromagnetic coil. Utility Model Content

[0027] Figures 1 to 6 This invention illustrates a device for positioning a coil assembly, which can be used to fix the spacing of coils. The device may include a plurality of first fixing frames 200 and second fixing frames 210 that cooperate to limit the spacing between adjacent coil segments 300, and a connecting unit that detachably connects the first fixing frames 200 and the second fixing frames 210. Each first fixing frame 200 is provided with a plurality of spaced-apart first limiting members 201, the distance between adjacent first limiting members 201 being greater than the diameter of the cross-section of the coil segment 300. Each second fixing frame 210 is provided with a plurality of spaced-apart second limiting members 211, the distance between adjacent second limiting members 211 being greater than the diameter of the cross-section of the coil segment 300. After the first fixing frames 200 and the second fixing frames 210 are connected, the first limiting members 201 abut against a first side of the coil segment 300, and the second limiting members 211 abut against a second side of the coil segment 300.

[0028] The first fixed frame 200 has a plurality of first limiting members 201, and the second fixed frame 210 has a plurality of second limiting members 211. The plurality of first limiting members 201 abut against the coil segment 300 along the first direction, and the plurality of second limiting members 211 abut against the coil segment 300 along the second direction. The first limiting members 201 and the second limiting members 211 completely clamp and fix both sides of a single coil, restricting the degree of freedom of the coil in other directions, so that the coil itself is completely limited, avoiding displacement and misalignment, ensuring the effective electromagnetic field and power are normal, and improving the stability of the electromagnetic induction heating equipment during operation.

[0029] Understandably, the first direction is Figure 6 The middle A direction, the second direction is Figure 6 In the B direction.

[0030] Understandably, the first fixing frame 200 and the second fixing frame 210 are paired with each other, with one first fixing frame 200 paired with one second fixing frame 210, and the first limiting member 201 and the second limiting member 211 are paired with each other, with one first limiting member 201 paired with one second limiting member 211.

[0031] In one specific embodiment, the contact points between the first limiting member 201 and the second limiting member 211 and the coil are provided with elastic material to prevent the first limiting member 201 and the second limiting member 211 from directly damaging the coil.

[0032] In one specific embodiment, the first limiting member 201 and the second limiting member 211 are made of insulating materials to prevent the coil from contacting the first limiting member 201 and the second limiting member 211 and transmitting electrical energy, thereby forming a tip discharge, causing arcing, and damaging the first limiting member 201 and the second limiting member 211.

[0033] In one specific embodiment, the first groove 202 and the second groove 212 penetrate through the first limiting member 201 and the second limiting member 211, so that the coil can be directly attached to the bottom of the first groove 202 and the second groove 212 without any protruding parts damaging the coil.

[0034] Figures 2 to 6 The first limiting member 201 and the second limiting member 211 are shown in one embodiment. Each of the first limiting members may have a first groove that abuts against and limits the coil segment 300; and / or each of the second limiting members may have a second groove that abuts against and limits the coil segment 300. When the first groove and the adjacent second groove abut against the coil segment 300 at the same time, the opening direction of the first groove is opposite to the opening direction of the second groove. The grooves with opposite openings can limit the coil segment 300 to each other, reduce the degree of freedom of the coil segment 300, and thus fix the coil segment 300.

[0035] Figures 3 to 6 The first limiting member 201 and the second limiting member 211 may, in one embodiment, include a recessed shape of the first groove and the second groove that matches the outer surface of the coil segment 300, or the first groove and the second groove are arc surfaces with the radius of the arc surface being the same as the outer radius of the coil segment 300.

[0036] In one specific embodiment, the outer surface of the coil is a shape other than a circle, and the recesses of the first groove 202 and the second groove 212 are the same as the outer surface of the coil. When the first groove 202 and the second groove 212 clamp the coil, the first groove 202 and the second groove 212 completely fit the surface of the coil and can completely press the coil.

[0037] In one specific embodiment, the outer surface of the coil is circular, and the first groove 202 and the second groove 212 are arc surfaces with the same radius as the outer circle radius of the coil. The arc surfaces of the first groove 202 and the second groove 212 completely fit the outer circle surface of the coil, which can completely compress the coil.

[0038] Figures 3 to 6 The first limiting member 201 and the second limiting member 211 are shown in one embodiment to include the first groove and the second groove having a recess depth greater than or equal to the coil radius, and / or the through hole size formed by the first groove and the second groove being joined together is greater than or equal to the outer circle size of the coil.

[0039] In one specific embodiment, the depth of the first groove 202 and the second groove 212 is greater than or equal to the radius of the coil. The first groove 202 and the second groove 212 can form a hole that can just accommodate the coil. The hole fits the coil perfectly, thus completely limiting the coil.

[0040] In one specific embodiment, when the shape of the first groove 202 and the second groove 212 is different from that of the coil, the size of the first groove 202 and the second groove 212 should be larger than the size of the coil to avoid the first groove 202 and the second groove 212 damaging the coil.

[0041] Figure 1 , Figure 2 and Figure 6 The first limiting member 201 and the second limiting member 211 are shown in one embodiment. The first fixing frame and the second fixing frame are offset in the axial direction of the coil segment 300. The first limiting member is disposed on one side of the cross-section of the coil segment 300, and the second limiting member is disposed on the other side of the coil segment 300 away from the cross-section of the first limiting member. The first limiting member and the second limiting member on both sides of the coil segment 300 can completely limit the spacing of the coil segment 300 and prevent the coil from moving.

[0042] Figures 3 to 6The first limiting member 201 and the second limiting member 211 are shown in one embodiment. The first limiting member 201 may be evenly distributed in a row on the first fixed frame 200, and a number of second limiting members 211 may be evenly distributed in a row on the second fixed frame 210. The even distribution in a row allows each first limiting member 201 and each second limiting member 211 to be paired with each other, and there will be no part of the first limiting member 201 and the second limiting member 211 that cannot be paired.

[0043] Figures 2 to 6 The first fixing frame 200 and the second fixing frame 210 are shown in one embodiment. The first fixing frame 200 and the second fixing frame 210 may have the same length. The number and position of the first limiting member 201 and the second limiting member 211 are matched. With the same length, the same number and the same position, the first fixing frame 200 and the second fixing frame 210 can be directly made into the same shape without having to be made into two different components. After the first fixing frame 200 and the second fixing frame 210 are reversed, the first limiting member 201 and the second limiting member 211 can completely limit and fix the coil.

[0044] Figure 3 and Figure 4 The connecting unit, as shown in one embodiment, may include a through hole 203 disposed on a first fixing frame 200 or a second fixing frame 210, a threaded hole 213 disposed on the first fixing frame 200 or the second fixing frame 210, and a fixing bolt passing through the through hole 203 and threadedly connected to the threaded hole 213; or, the connecting unit includes a plug groove disposed on the first fixing frame 200 or the second fixing frame 210, and a plug-in disposed on the first fixing frame 200 or the second fixing frame 210, wherein the plug-in is matched with the position of the plug groove.

[0045] In one specific embodiment, the first fixing bracket 200 and the second fixing bracket 210 can be completely locked together by bolts passing through the through hole 203 and the threaded hole 213.

[0046] In one specific embodiment, the through hole 203 and the threaded hole 213 are respectively disposed at both ends of the first fixing bracket 200 and the second fixing bracket 210.

[0047] In one specific embodiment, the insertion slot and the insertion piece are interference fit. When the insertion piece is inserted into the insertion slot, the first fixing bracket 200 and the second fixing bracket 210 can be snapped together.

[0048] Figure 1 The first fixing frame 200 and the second fixing frame 210 are shown in one embodiment. A frame 100 is provided on one side of the coil assembly. Part or all of the first fixing frame 200 and the second fixing frame 210 are fixed on the frame 100. The frame 100 can fix the first fixing frame 200 and the second fixing frame 210.

[0050] Figure 1 The mounting plate 110 is shown in one embodiment and may include three layers. The mounting plate 110 is connected to both ends and the middle of the first fixing frame 200 and the second fixing frame 210 respectively, which improves the rigidity of the frame 100 and greatly enhances the overall stability of the device.

[0051] In one specific embodiment, the number of mounting plates 110 can be greater than three, and the number of mounting plates 110 is increased according to the actual length of the first fixing frame 200 and the second fixing member.

[0052] In one specific embodiment, the first fixing frame 200 is inserted into the wound coil assembly, such that each first limiting member 201 is located between adjacent coil segments 300, and each first limiting member 201 abuts against the coil segment 300 along a first direction; then, the second fixing frame 210 is inserted into the coil assembly, such that each second limiting member 211 is located between adjacent coil segments 300, and each second limiting member 211 abuts against the coil segment 300 along a second direction, and the corresponding first limiting member 201 and second limiting member 211 clamp the corresponding coil segment 300 from both sides. The entire operation process can be completed by directly operating the first fixing frame 200 and the second fixing frame 210 without moving each coil segment 300. The structure is simple and the operation is convenient.
