[0050] a base 2;

[0051] a rotating clamp 3 mounted at one end of the base 2 and used for clamping and rotating the first workpiece 11;

[0052] a moving clamp assembly 4 used for clamping the second workpiece 12 and moving it towards the first workpiece 11, so as to friction weld a welded product, which is arranged at the other end of the base 2;

[0053] and a feeding and discharging assembly 5 used for clamping and moving the first workpiece 11, the second workpiece 12 and the welded product, which comprises a base 51, a mechanical arm 52 connected to the base 51, and a clamping piece 53 arranged at the end of the mechanical arm 52.

[0054] In this embodiment, the clamping piece 53 is a clamping jaw.

[0055] In this embodiment, the moving clamp assembly 4 comprises:

[0056] a first mounting bracket 41 mounted at the end of the base 2 away from the rotating clamp 3;

[0057] a hydraulic jack cylinder 42 mounted on the first mounting bracket 41;

[0058] a connecting seat 43 connected to the moving end of the hydraulic jack cylinder 42;

[0059] and a plurality of clamping cylinders 44 mounted on the connecting seat 43 and used for clamping the second workpiece 12.

[0060] In this embodiment, a second mounting bracket 45 for mounting the clamping cylinders 44 is arranged on the connecting seat 43, the clamping cylinders 44 are mounted on the second mounting bracket 45, and two of them are arranged opposite to each other on both sides of the second workpiece 12.

[0061] In this embodiment, the mechanical arm 52 is a six-axis robot, which can realize complex motion in three-dimensional space.

[0062] In this embodiment, the friction welding device further comprises a conveying belt assembly 6 arranged on the same side of the feeding and discharging assembly 5 and used for placing and conveying the first workpiece 11 and the second workpiece 12, and the conveying direction of the conveying belt assembly 6 is perpendicular to the connecting line direction of the rotating clamp 3 and the moving clamp assembly 4.

[0063] In the embodiment, the conveying belt assembly 6 comprises:

[0064] a rack 61;

[0065] a driving roller 62 and a driven roller 63 mounted on the rack 61;

[0066] a conveying belt 64 stretched between the driving roller 62 and the driven roller 63;

[0067] and a motor 65 connected with the driving roller 62 and driving the rotation of the driving roller 62.

[0068] In the embodiment, the driving roller 62 is mounted on the rack 61 through a first support 621, and the driven roller 63 is mounted on the rack 61 through a second support 631, and the second support 631 is arranged close to one end of the base 2.

[0069] In the embodiment, the first and second pieces to be welded 11 and 12 are flower basket forks.

[0070] The working principle of the friction welding device in the embodiment is as follows:

[0071] The first and second pieces to be welded 11 and 12 are placed on the surface of the conveying belt 64 by manual operation, the motor 65 is started, and the conveying belt 64 moves towards the base 2. When the first and second pieces to be welded 11 and 12 are conveyed to the end of the conveying belt 64, the motor 65 stops running, the mechanical arm 52 moves, the first piece to be welded 11 is clamped by the clamping member 53 and placed on the rotary clamp 3, and the second piece to be welded 12 is clamped by the clamping member 53 and placed between the clamping cylinders 44. At this time, the rotary clamp 3 rotates to drive the first piece to be welded 11 to rotate, the hydraulic top cylinder 42 works to drive the connecting seat 43 to move towards the rotary clamp 3, thereby driving the second piece to be welded 12 to move towards the first piece to be welded 11, and the relative movement between the first and second pieces to be welded 11 and 12 generates heat to make the metal on the contact surface reach a plastic state, and then the first and second pieces to be welded 11 and 12 are joined under the action of pressure to obtain a welded product. In the friction welding process, the first and second pieces to be welded 11 and 12 are not melted, and the welded joint is formed in a solid state. After the friction welding is completed, the welded product is taken out by the mechanical arm 52 and the clamping member 53 and placed in the next process, waiting for the next operation.

[0072] When the robotic arm 52 and the gripper 53 remove the first piece to be welded 11 and the second piece to be welded 12 from the surface of the conveyor belt 64, the motor 65 starts and moves the next set of the first piece to be welded 11 and the second piece to be welded 12 to the end point of the conveyor belt 64, waiting for the robotic arm 52 and the gripper 53 to grip them, and the cycle is repeated.

[0073] Example 2

[0074] like Figure 1 As shown, most aspects are the same as in Embodiment 1, except that in this embodiment, the bottom of the connecting seat 43 is equipped with several sliders 431, and the base 2 is provided with a slide rail 21 for the sliders 431 to slide. One end of the slide rail 21 faces the rotating clamp 3, and the other end faces the moving clamping assembly 4. This arrangement reduces the force required by the hydraulic top cylinder 42 to drive the second workpiece 12 to be welded, resulting in a smoother movement and ensuring the accuracy of welding the first workpiece 11 and the second workpiece 12.

[0075] Example 3

[0076] Compared to Embodiment 1, most aspects are the same, except that the surface of the conveyor belt 64 is provided with a plurality of limiting blocks 641 for limiting the position of the first workpiece 11 and the second workpiece 12 to be welded and preventing them from shifting. The limiting blocks 641 are arranged at equal intervals along the transport direction of the conveyor belt 64, and the distance between two adjacent limiting blocks 641 is equal to the maximum width of the first workpiece 11 or the second workpiece 12 to be welded.

[0077] Example 4

[0078] like Figure 2 and 3 As shown, it is almost identical to Embodiment 3, except that the second bracket 631 is provided with a sensor 7 for detecting the position of the first workpiece 11 and the second workpiece 12 to be welded. The sensor 7 is wired to a controller, which is wired to the motor 65 and the loading / unloading assembly 5.

[0079] In this embodiment, the sensor 7 is a photoelectric switch, and the controller is a PLC controller.

[0080] The working principle of the friction welding device described in this embodiment is as follows:

[0081] The first and second pieces to be welded 11 and 12 are placed on the surface of the conveyor belt 64 by hand, the motor 65 is started, and the conveyor belt 64 moves towards the base 2. When the photoelectric switch receives the sensing signal of the first and second pieces to be welded 11 and 12, the signal is transmitted to the controller, the controller controls the motor 65 to stop running, the mechanical arm 52 to move, the first piece to be welded 11 is clamped by the clamping member 53 and placed on the rotary clamp 3, and the second piece to be welded 12 is clamped by the clamping member 53 and placed between the clamping cylinders 44. At this time, the rotary clamp 3 rotates to drive the first piece to be welded 11 to rotate, the hydraulic top cylinder 42 works to drive the connecting seat 43 to move towards the rotary clamp 3, thereby driving the second piece to be welded 12 to move towards the first piece to be welded 11, the relative movement and friction between the first and second pieces to be welded 11 and 12 generate heat, the metal of the contact surface reaches a plastic state, and then the first and second pieces to be welded 11 and 12 are joined under the action of pressure to obtain a welded product. In the friction welding process, the first and second pieces to be welded 11 and 12 are not melted, and the welded joint is formed in a solid state. After the friction welding is completed, the welded product is taken out by the mechanical arm 52 and the clamping member 53 and placed at the next process for the next operation.

[0082] When the first and second pieces to be welded 11 and 12 are taken away from the surface of the conveyor belt 64 by the mechanical arm 52 and the clamping member 53, the photoelectric switch cannot receive the sensing signal of the first and second pieces to be welded 11 and 12, which is transmitted to the controller, the motor 65 is started, the next set of first and second pieces to be welded 11 and 12 is moved to the end of the conveyor belt 64, and the mechanical arm 52 and the clamping member 53 are clamped for cyclic operation.

[0083] The above description of the embodiments is for the purpose of enabling a person of ordinary skill in the art to understand and use the utility model. Those skilled in the art can easily make various modifications to the embodiments and apply the general principles described herein to other embodiments without inventive labor. Therefore, the utility model is not limited to the above embodiments, and improvements and modifications made by those skilled in the art without departing from the scope of the utility model should be within the scope of protection of the utility model.
