DETAILED DESCRIPTION
[0017] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0018] Referring to Figures 1 to 4 The utility model provides a door ring laser welding electromagnetic adsorption device, include: adsorption module component 1, adsorption module component 1 is set up in the work platform 9 surface through permanent magnet base 2, adsorption module component 1 is composed of electric permanent magnet assembly 5, fixed support 3 and permanent magnet base 2, and fixed support 3 is composed of top plate 11, vertical plate 13 and bottom plate 15, and the top plate 11 upper surface is fixedly connected air blowing assembly 7 and back dust removal assembly 8 respectively, and vertical plate 13 surface is fixedly connected permanent magnet base 2 through bolt, and bottom plate 15 both ends symmetrically screw support leveling bolt 4, while the top plate 11 upper surface is symmetrically provided with lifting groove, and magnet leveling bolt 6 is screwed in the bottom of lifting groove inner chamber, and lifting block 12 is slidably connected in lifting groove through magnet leveling bolt 6, and the lifting block 12 upper surface is fixedly connected buffer block 10, and buffer block 10 is fixedly connected in the recess of electric permanent magnet assembly 5 lower surface.
[0019] In the embodiment, the number of the adsorption module components 1 arranged on the surface of the workbench 9 of the electromagnetic adsorption device is determined by the number of the door ring welding sub-components. When there are five door ring welding sub-components, there are five groups of the adsorption module components 1 of the electromagnetic adsorption device, and the five groups of the modularly designed adsorption module components 1 are consistent in height and width except for the length, thereby improving the use flexibility of the electromagnetic adsorption device. For different models of door rings, different lengths of the adsorption module components 1 can be flexibly matched. Meanwhile, the module interfaces of the adsorption module components 1 are consistent and can be mutually used. When the two groups of the electric permanent magnet assemblies 5 arranged on the upper surface of the fixed support 3 need to be leveled, the magnet leveling bolts 6 are rotated, the magnet leveling bolts 6 will push the corresponding side of the buffer block 10 and the electric permanent magnet assembly 5 through the screwed lifting blocks 12, thereby achieving the leveling of the two groups of the electric permanent magnet assemblies 5, and ensuring that the upper surfaces of the two groups of the electric permanent magnet assemblies 5 can be in the same horizontal plane. In the actual use process, the two groups of the permanent magnet seats 2 of the adsorption module components 1 are adsorbed and fixed on the surface of the workbench 9, thereby omitting the screw fixing step, and the efficiency of the assembly and disassembly and adjustment of the adsorption module components 1 can be effectively improved. After a plurality of groups of the adsorption module components 1 are adsorbed and fixed on the surface of the workbench 9, the horizontal plane of the corresponding adsorption module components 1 can be adjusted through the support leveling bolts 4, so that the upper surfaces of the plurality of groups of the adsorption module components 1 on the workbench 9 for electromagnetic adsorption can be in the same plane, thereby omitting the traditional gasket leveling step and assisting in improving the adjustment efficiency. Then, the door ring sub-component to be laser welded is placed on the surface of the corresponding adsorption module component 1, the switch of the electric permanent magnet assembly 5 is started and quickly turned off, so that the electric permanent magnet body in the electric permanent magnet assembly 5 can be magnetized instantaneously in the energized state, and then the adsorption module component 1 can magnetically attract and fix the door ring welding sub-component. When demagnetization is needed, the electric permanent magnet assembly 5 is powered on and then powered off again, so that the electric permanent magnet body in the electric permanent magnet assembly 5 can complete demagnetization after being powered on, thereby releasing the magnetic attraction and fixation of the adsorption module component 1 to the door ring welding sub-component. In the use process, the base plate of the electric permanent magnet assembly 5 does not generate heat, so that it is not necessary to additionally arrange a water channel for cooling, thereby avoiding the risk of water leakage. Moreover, the demagnetization speed is fast. Meanwhile, the air blowing assembly 7 and the back dust removal assembly 8 arranged in the electromagnetic adsorption device can adsorb and clean the dust generated in the welding process, and increase the welding seam protection gas function, thereby ensuring the welding seam quality.
[0020] As a preferable implementation, the cross section of the fixed support 3 is in a convex shape structure, and the top plate 11 in the fixed support 3 is in a rectangular structure, and four groups of lifting grooves are parallel and equally spaced at both ends of the upper surface of the top plate 11, and the eight groups of lifting grooves on the upper surface of the top plate 11 are all in a rectangular structure.
[0021] In the embodiment, as shown in Figure 1 and Figure 2The eight sets of lifting slots on the upper surface of the top plate 11 are directly opposite the four corners of the two sets of electro-permanent magnet assemblies 5, which facilitates the subsequent leveling of the electro-permanent magnet assemblies 5.
[0022] In a preferred embodiment, the lifting block 12 has a rectangular parallelepiped structure. The dimensions of the outer side of the lifting block 12 are matched with the dimensions of the lifting groove.

Meanwhile, the buffer block 10 fixedly connected to the upper surface of the lifting block 12 has a square structure, and the size of the buffer block 10 is larger than the size of the upper surface of the lifting block 12.
[0023] In this embodiment, as Figure 1 and Figure 2 The lifting block 12 and the lifting groove are matched in size, which helps to enhance the stability of the lifting block 12 when it moves and avoids the problem of tilting during the movement. At the same time, the buffer block 10 is made of rubber, so the lifting block 12 and the electro-permanent magnet assembly 5 can make corresponding angle changes, thereby helping to improve the leveling efficiency of the electro-permanent magnet assembly 5 and ensuring that the upper surfaces of the two sets of electro-permanent magnet assemblies 5 can be in the same horizontal plane.
[0024] In a preferred embodiment, two sets of vertical plates 13 are symmetrically connected to both sides of the lower surface of the top plate 11, and the end faces of the two sets of vertical plates 13 are L-shaped. The top plate 11 and the bottom plate 15 are fixedly connected to the upper and lower surfaces of the vertical plates 13, respectively. At the same time, the edges of the lower surface of the vertical plates 13 are symmetrically inclined.

[0026] In a preferred embodiment, multiple sets of screw holes are opened at equal intervals along the length direction on the upper end of the surface of the upright plate 13, and multiple sets of positioning blocks 14 are fixedly connected at equal intervals along the length direction on the end face of the bent part of the upright plate 13, and the multiple sets of positioning blocks 14 are all cylindrical structures.
[0027] In this embodiment, as Figure 1 and Figure 2 The screw holes on the surface of the upright plate 13 facilitate the fixed connection between the permanent magnet base 2 and the fixed bracket 3, while the positioning block 14 helps to enhance the stability of the connection between the permanent magnet base 2 and the upright plate 13.
[0028] As a preferred implementation, the permanent magnet seat 2 is in a convex structure, a through hole is formed on the upper end of the convex part of the permanent magnet seat 2 corresponding to the position of the threaded hole, the bolt is screwed into the threaded hole formed on the surface of the vertical plate 13 through the through hole, and a positioning hole is formed on the surface of the main body of the permanent magnet seat 2 corresponding to the position of the positioning block 14.
[0029] In this embodiment, as Figure 1 and Figure 2 , the notch structure at both ends of the upper surface of the permanent magnet seat 2 can avoid the problem of mutual interference between the permanent magnet seat 2 and the magnet leveling bolt 6, so that the magnet leveling bolt 6 can be conveniently rotated, and the size of the positioning hole and the positioning block 14 is matched, so as to assist in enhancing the stability of the connection between the fixed support 3 and the permanent magnet seat 2.
[0030] As a preferred implementation, the bottom plate 15 is in a whole back-shaped structure, the length of the bottom plate 15 is greater than the length of the top plate 11, and the length of the top plate 11 is greater than the length of the vertical plate 13, and the upper surface of the bottom plate 15 is symmetrically screwed with four groups of support leveling bolts 4 through auxiliary parts, and the upper surface of the top plate 11 is symmetrically connected with two groups of electric permanent magnet assemblies 5 through lifting blocks 12, and the electric permanent magnet assemblies 5 are in a cuboid structure.
[0031] In this embodiment, as Figure 1 and Figure 2 , the setting of the support leveling bolt 4 makes the fixed support 3 be able to be leveled on the surface of the workbench 9, thereby ensuring that the upper surfaces of the multiple groups of adsorption module components 1 are in the same horizontal plane, and the movable connection structure between the electric permanent magnet assembly 5 and the fixed plate makes the two groups of electric permanent magnet assemblies 5 on the upper surface of the same fixed support 3 be in the same horizontal plane.
[0032] The door ring laser welding electromagnetic adsorption device of the utility model cooperates the electric permanent magnet assembly 5, the fixed support 3, the permanent magnet seat 2, the support leveling bolt 4 and the magnet leveling bolt 6, so that the electromagnetic adsorption device can be conveniently adjusted in position, the efficiency of magnetically attracting and fixing the door ring is improved, different sizes and shapes of door rings can be adsorbed and fixed, the practicability of the electromagnetic adsorption device is enhanced, and the problems of water leakage, heating and slow demagnetization can be effectively avoided.
