[0025] The utility model is described in detail below in combination with the drawings.

[0026] As Figs. 1 to 3 shown, the utility model relates to a friction welding device with deburring effect, including workbench 1, set up in the positioning device 2 of workbench 1, the first limiting device 3 and the second limiting device 4 of vertical setting with positioning device 2 and set up in the friction welding machine 5 of workbench 1 side, the friction welding machine 5 includes stirring head 51, set up in the stirring needle 52 of stirring head 51, with the drive motor 53 of drive connection of stirring head 51, with the drive motor 53 drive connection of Z-axis module 54 and with the drive connection of numerical control sliding table 55 of Z-axis module 54, the positioning device 2, first limiting device 3, second limiting device 4 are around the circumferential of workbench 1 and are equipped, first limiting device 3 and second limiting device 4 are spaced and parallelly arranged, the stirring head 51 rotation is contacted in first limiting device 3 and second limiting device 4, to make stirring needle 52 protrude into first limiting device 3 and second limiting device 4 between.

[0027] Batch edge refers to the sharp and irregular edge formed at the corner or edge of the product during processing due to improper mold design or operation, etc. This phenomenon is common in products formed by molds, such as plastics, hardware, etc., especially at the joint position of the mold. Batch edge can cause many problems in actual production, such as appearance defects, and even damage to the product. In the heat dissipation system of new energy vehicles, the most critical component is the water cooling plate. Currently, a widely used solution in the new energy vehicle field is aluminum extruded water cooling plate profile, which is then processed into water channels. Typically, two profiles are spliced together using friction stir welding technology to increase the heat dissipation area of the water cooling plate. During operation, the two profiles are placed on the workbench 1 corresponding to the position of the workbench 1, and the positioning device 2 is used to fix the outer edge position of the two profiles. The numerical control sliding table 55 drives the Z-axis module 54 to move to the upper position of the two profiles, and the Z-axis module 54 drives the driving motor 53 to move downward. The driving motor 53 drives the stir head 51 to rotate, and the rotating stir head 51 drives the stir pin 52 to extend into the joint between the two profiles. The high-speed rotation of the stir head 51 causes the stir head 51 to rub against the surface of the profile, thereby causing the material at the joint to soften due to the friction heat between the stir head 51 and the profile. The material of the profile undergoes strong plastic deformation due to the friction heat between the stir head 51 and the profile. The stir head 51 moves forward under the drive of the numerical control sliding table 55, and the highly plastic deformed material gradually deposits behind the stir head 51, forming a dense solid-phase weld under the extrusion of the stir head 51. Then the first limiting device 3 and the second limiting device 4 are arranged in parallel and spaced apart, and located on the left and right sides of the weld. The Z-axis module 54 drives the driving motor 53 to move downward, so that the stir head 51 rotates and contacts the first limiting device 3 and the second limiting device 4, effectively limiting the position of the stir head 51, so that the stir pin 52 protrudes between the first limiting device 3 and the second limiting device 4, ensuring that the rotating stir pin 52 grinds the batch edge around the weld. At the same time, the external air extractor is used to remove the molten batch edge slag, and the batch edge quality is high. The utility model has the advantages of compact structure and reasonable design, which realizes the welding work and also considers the removal of batch edge function, has high batch edge removal efficiency, saves time and effort, and improves production capacity and efficiency.

Specifically, the translation cylinder 22 drives the translation seat 23 to move forward and backward relative to the base 21, so that the rotating arm 24 moves to a position close to the profile, the rotating arm 24 rotates relative to the translation seat 23 through the hinge shaft 25, which facilitates the rotating arm 24 to press and fix the position of the profile through the pad 26, and the pad 26 is made of high-activity adsorption material, such as silica gel, which effectively avoids scratching the surface of the profile, protects the appearance of the profile, and improves the yield.
