[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0023] like Figure 1 As shown, an electric vehicle steel wheel welding device includes a workbench 1, a drive mechanism 2 placed on the right side of the workbench 1, a welding assembly 6 fixedly connected to the upper end of the workbench 1, a motor 3 fixedly connected to the middle of the upper end of the workbench 1, a turntable fixedly connected to the output end of the motor 3 via a coupling, a support plate 4 fixedly connected to the upper end of the turntable, lifting and rotating assemblies 7 fixedly connected to the rear and left sides of the upper part of the workbench 1, and several placement assemblies 5 movably connected in a ring array on the upper end of the support plate 4.
[0024] In the specific implementation process of this utility model, the spokes, outer ring and cup of the electric vehicle steel rim are first placed on the placement component 5 in front. Then, the motor 3 is started to drive the turntable to rotate. Then, the turntable drives the support plate 4 to rotate 45 degrees. Then, the internal drive structure of the drive mechanism 2 is started to drive the placement component 5 to rise on the support plate 4, so that the steel rim component inside the placement component 5 is pre-pressed with the inside of the welding component 6. After the pre-pressing is completed, the placement component 5 is lowered to the initial position by the drive mechanism 2.
[0025] Then, the motor 3 drives the support plate 4 to rotate 45 degrees, and then the rear lifting and rotating component 7 is activated to drive the placement component 5 to rise and contact the internal structure of the welding component 6. While driving the placement component 5 to rise, the placement component 5 can fix the steel ring so that it will not shift during the welding process. Then, the internal structure of the welding component 6 is activated to weld the spokes inside the steel ring to the connection with the outer ring. At the same time, the internal drive structure of the rear lifting and rotating component 7 is activated to drive the placement component 5 to rotate, thereby driving the steel ring to rotate 360 degrees for welding. After the welding of the connection with the outer ring is completed, the lifting and rotating component 7 drives the placement component 5 to descend.
[0026] Then, motor 3 drives the support plate 4 to rotate 45 degrees. Then, the internal structure of the lifting and rotating assembly 7 on the left is activated to drive the placement assembly 5 to rise. As the placement assembly 5 rises, it fixes the steel ring. Then, the internal structure of the welding assembly 6 is activated to weld the connection between the steel ring spokes and the small bowl. At the same time, the internal drive structure of the lifting and rotating assembly 7 is activated to drive the placement assembly 5 to rotate 360 degrees for welding. After welding is completed, the lifting and rotating assembly 7 drives the placement assembly 5 to fall. Then, motor 3 drives the support plate 4 to rotate, which in turn drives the placement assembly 5 to rotate 45 degrees back to the front of the entire device. Then, the welded steel ring can be taken out.
[0027] Specifically, in order to achieve the purpose of pre-compressing the steel wheel components, refer to Figure 2 and Figure 3 In this solution, the welding assembly 6 includes a support platform 61, which is fixedly connected to the upper end of the workbench 1. A pressure block 63 is fixedly connected to the lower right side of the support platform 61, and welding heads 62 are fixedly connected to the rear and left sides of the upper end of the support platform 61.
[0028] Furthermore, the drive mechanism 2 includes an oil tank 21 and an oil cylinder 23. The oil tank 21 is located on the right side of the workbench 1. The oil cylinder 23 is fixedly connected to the lower right side of the workbench 1. A second motor 22 is fixedly connected to the upper rear side of the oil tank 21. A first protrusion 24 is fixedly connected to the output end of the oil cylinder 23. A pump is fixedly connected to the output end of the second motor 22 through a coupling.
[0029] In the above process, when the support plate 4 drives the placement component 5 to rotate above the first protrusion 24, the second motor 22 is started to drive the pump to run. The oil pumped out from the oil tank 21 flows through the pipeline to the control valve, and then the control valve guides the hydraulic oil to the oil cylinder 23, so that the oil cylinder 23 drives the placement component 5 to rise upward, so that the steel ring component inside the placement component 5 contacts the lower end of the pressure block 63 to form a pre-pressure operation.
[0030] The specific installation method, circuit connection method, and control method of the motor 22 used above are all conventional designs, and will not be described in detail in this utility model.
[0031] Specifically, in order to drive the placement component 5 to perform lifting, rotating, and welding, refer to Figure 5 In this solution, the lifting and rotating assembly 7 includes two fixed disks 73 and two air pumps 71. The two fixed disks 73 are slidably connected to the rear and left sides of the worktable 1, respectively. The two air pumps 71 are fixedly connected to the lower rear and left sides of the worktable 1, respectively. Motors 72 are fixedly connected to the lower ends of the two fixed disks 73, and protrusions 74 are rotatably connected to the upper middle parts of the two fixed disks 73.
[0032] Furthermore, the output ends of both air pumps 71 pass through the lower end of the workbench 1 and are fixedly connected to the lower end of the fixed plate 73 on the same side. The output ends of both motors 72 pass through the lower end of the motors 72 on the same side and are fixedly connected to the lower end of the protrusion 74 on the same side via a coupling.
[0033] In the above process, after the support plate 4 drives the placement component 5 to rotate above the rear protrusion 74, the rear air pump 71 is started to drive the fixed plate 73 to rise. Then, as the fixed plate 73 rises, the motor 72 rises, which in turn lifts the placement component 5 upward through the protrusion 74. Then, the motor 72 is started to drive the protrusion 74 to rotate on the surface of the fixed plate 73, which in turn drives the placement component 5 to rotate 360 degrees, so that the welding head 62 can perform rotational welding on the lower placement component 5.
[0034] The specific installation method, circuit connection method, and control method of the motor 372 used above are all conventional designs, and will not be described in detail in this utility model.
[0035] Specifically, in order to fix the steel ring during the welding process, refer to Figure 4 In this scheme, the placement component 5 includes a plurality of support columns 51 and a plurality of annular grooves 59. The plurality of support columns 51 are movably connected in an annular array to the inside of the support disk 4. The plurality of annular grooves 59 are annularly arrayed at the lower end of the support disk 4. The upper end of the plurality of support columns 51 is fixedly connected to a placement disk 52. The upper middle part of the upper end of the plurality of placement disks 52 is fixedly connected to a suction cup 53. The upper part of the inner cavity of the plurality of support columns 51 is fixedly connected to a round tube 54. The outer surface of the plurality of support columns 51 is provided with a sliding groove 55 at the end away from the same side axis. The inner cavity of the plurality of round tubes 54 is slidably connected to a piston plate 56. The lower end of the plurality of piston plates 56 is fixedly connected to a C-shaped column 57. The end of the plurality of C-shaped columns 57 away from the same side piston plate 56 is rotatably connected to a rotating disk 58.
[0036] Furthermore, the inner cavities of several annular grooves 59 are all T-shaped, the rotating disks 58 are all movably connected to the inner cavities of the annular grooves 59 on the same side, the middle parts of several suction cups 53 are all connected to the inner cavities of the circular tubes 54 on the same side, and the lower ends of several support columns 51 are all provided with grooves.
[0037] In the above, when protrusion 24 or protrusion 74 is pushed upward, it engages with the groove at the lower end of the support column 51, thus pushing the support column 51 upward. At the same time as the support column 51 moves upward, the rotating disk 58 contacts the upper wall of the inner cavity of the annular groove 59, so that the support column 51 remains stationary while it rises. This causes the round tube 54 to slide upward on the outer surface of the piston plate 56, making the air in the inner cavity of the round tube 54 uniform and the air pressure in the inner cavity of the round tube 54 lower than the external air pressure, thereby achieving the purpose of fixing the suction cup 53 to the lower end face of the steel ring.
[0038] When the support column 51 is rotated, the rotating disk 58 is driven to rotate around the axis of the support column 51 in the inner cavity of the annular groove 59, thus ensuring that the steel ring remains fixed while rotating.
[0039] It should be noted that the specific installation method, circuit connection method and control method of the air pump 71 used in this utility model are all conventional designs, and will not be described in detail in this utility model.
[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
