Abstract
Description
Technical Field
[0001] This utility model relates to the field of friction welding technology, and in particular to an adjustable angle friction stir welding device. Background Technology
[0002] Friction stir welding utilizes the heat generated by the friction between the end faces of workpieces to bring them to a plastic state, followed by upsetting to complete the welding. Friction welding was invented to address these phenomena, as chips often adhere firmly to the cutting tool during machining, and poor lubrication between shafts and bearings can also lead to localized welding. Friction welding can be divided into two types: continuous drive friction welding and inertial friction welding.
[0003] Existing friction stir welding machines cannot adjust their angle during use, making it impossible to perform friction stir welding operations on different workpieces and thus failing to meet usage requirements. Therefore, this utility model proposes an adjustable angle friction stir welding device. Utility Model Content

By setting an angle adjustment component between the main body of the device and the rotating disk, when the output head needs angle adjustment, the output end of the drive motor drives the gear to mesh, thereby adjusting the angle of the rotating disk, drive housing, and output head. After the output head angle is adjusted, the output ends of two sets of brake cylinders drive the pressure sensor and brake plate to squeeze the rotating column.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-5 This utility model provides a technical solution for an adjustable angle friction stir welding device: An adjustable angle friction stir welding device includes a device body 1, a clamping component 2 and a drive housing 3 at the upper end of the device body 1, an output head 4 on one side of the drive housing 3, a rotating disk 5 at the bottom of the drive housing 3, an angle adjustment component 6 between the rotating disk 5 and the device body 1, a servo motor 7 at the upper end of the drive housing 3, a conveyor belt 8 connected to the output end of the servo motor 7, a support frame 9 on one side of the device body 1, and an auxiliary frame 10 and a welding workpiece 11 at the upper end of the support frame 9;
[0022] The angle adjustment component 6 includes a rotating column 61 with teeth 62 on its outer side. A drive motor 63 is installed at the bottom of the main body 1, and a gear 64 is installed at the output end of the drive motor 63. A brake cylinder 65 is installed on the outer side of the main body 1, and a pressure sensor 66 is installed at the output end of the brake cylinder 65. A brake plate 67 is installed at the detection end of the pressure sensor 66, and a guide rod 68 is installed on the outer side of the brake plate 67. A guide hole 69 is opened in the middle of the main body 1.
[0023] like Figure 1-3As shown, the input end of the drive housing 3 is connected to the output end of the servo motor 7 via a conveyor belt 8. The output head 4 is aligned with the end of the welding workpiece 11. There are two sets of auxiliary frames 10, which are symmetrically distributed. The servo motor 7 is connected to the drive housing 3 via bolts. The rotating disk 5 is a disc structure. The rotating disk 5 is connected to the main body 1 of the device via an angle adjustment component 6. A control panel is installed on the upper end of the main body 1, which facilitates the friction stir welding operation on the welding workpiece 11.
[0024] like Figure 2-5 As shown, the rotating column 61 and the rotating disk 5 are fixedly connected. A bearing seat is provided at the connection between the rotating column 61 and the main body 1 of the device, and the two are movably connected through the bearing seat. The number of teeth 62 is several sets and they are arranged in an array. The drive motor 63 is connected to the main body 1 of the device by bolts. The output end of the drive motor 63 is fixedly connected to the gear 64. The gear 64 meshes with the teeth 62. The number of brake cylinders 65 is two sets and they are symmetrically distributed. The output end of the brake cylinder 65 is fixedly connected to the pressure sensor 66. The detection end of the pressure sensor 66 is fixedly connected to the brake plate 67. The number of brake plates 67 is two sets and they are symmetrically distributed. The guide rod 68 is fixedly connected to the brake plate 67. The guide hole 69 is adapted to the guide rod 68, which is conducive to adjusting the angle of the drive housing 3 and the output head 4 to meet the usage requirements.
[0025] The working principle of this utility model is as follows: During the use of the device, the welding workpiece 11 is positioned by the clamping assembly 2 and the auxiliary frame 10. At the same time, the output end of the servo motor 7 drives the conveyor belt 8 to transmit power to the input end of the drive housing 3, which further drives the output head 4 and the welding workpiece 11 to rotate, so that the welding workpiece 11 and the parts to be welded can perform stir friction welding operation. When the angle of the output head 4 needs to be adjusted, the angle adjustment assembly 6 is controlled by the control panel to drive the rotating disk 5 and the drive housing 3 to adjust the angle.
[0026] It should be noted that, through the setting of the angle adjustment component 6, when the output head 4 needs angle adjustment, the output end of the drive motor 63 drives the gear 64 to mesh with the teeth 62, causing the rotating column 61 to rotate along the inside of the bearing seat, while simultaneously driving the rotating disk 5 and the drive housing 3 to rotate, further adjusting the position of the output head 4 to meet the usage requirements. After the angle adjustment of the output head 4 is completed, the output end of the drive motor 63 stops running, and then drives the output ends of the two sets of brake cylinders 65 to drive the pressure sensor 66 and the brake plate 67 to squeeze the rotating column 61, while simultaneously driving the guide rod 68 to move along the inside of the guide hole 69. At the same time, the pressure sensor 66 detects the clamping pressure, and when it reaches the set value, it feeds back to the control panel to control the output end of the brake cylinder 65 to stop running, thereby clamping and fixing the rotating column 61, ensuring the stability of the drive housing 3 and the output head 4 during operation.
[0027] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
