[0002] Friction welding, as an efficient and environmentally friendly connection technology, has demonstrated its unique advantages in many industrial fields. In particular, with the rapid development of materials science, automation control technology and computer technology, the design and performance of friction welding machines have been significantly improved, becoming an indispensable advanced process for connecting metals and certain non-metallic materials. Friction welding is a solid-state welding technology that uses the friction heat generated by the high-speed rotating workpiece or tool to make the surface to be welded reach a plastic state, and then achieves atomic bonding under pressure to form a strong welded joint. In this process, the material does not go through the melting stage, thus avoiding the metallurgical defects that may be caused by traditional fusion welding, such as pores and slag inclusions, and is particularly suitable for welding materials with high melting points, easy oxidation or heat sensitivity.

[0003] At present, when using a traditional friction welding machine to friction weld the surface of a product, the weldment is usually fixed on a fixture, and then the weldment is brought close to the surface of the product, and then the fixture is used to drive the weldment to rotate at high speed, so that the contact surface of the weldment and the product reaches a plastic state through frictional heat generation, and then the atoms are bonded under pressure, so that the weldment is fixed on the product through friction welding; however, during the use of the above-mentioned traditional friction welding machine, since the weldment and the surface of the product are generally coated with a coating, and these coatings are prone to form tiny particles similar to slag when frictional heat is generated, causing splashing, the surface of the product is easily adhered to the tiny particles to form residues, resulting in the need for manual use of grinding tools to carefully remove the residues on the surface of the product during subsequent processing, which is not only troublesome to operate, but also time-consuming and labor-intensive.

[0032] See also Figure 6 As shown, the close contact mechanism includes a connecting plate 20 and a spring 21; the connecting plate 20 is installed inside the movable frame 11; the two ends of the spring 21 are respectively connected to the connecting plate 20 and the sliding rod 12, and the elastic force of the spring 21 can make the grinding knife 13 on the sliding rod 12 close to the surface of the product 101.

[0033] When the welded part needs to be welded to the surface of product 101 by friction welding, first fix product 101 on mobile platform 2, then fix the welded part by fixture 6, then control mobile platform 2 to drive product 101 to move right, so as to adjust the position of product 101, until the position on product 101 to be welded is aligned with the welded part on fixture 6, then drive slide plate Ⅱ7 to move backward by electric push rod Ⅱ15, so as to drive fixture 6 and welded part to move backward, until welded part contacts the surface of product 101, then drive fixture 6 and welded part to rotate at high speed by servo motor 16, so that welded part rotates at high speed on the surface of product 101, so that the contact surface between welded part and product 101 reaches plastic state through friction heat generation, Until the welded part is fixed on the product 101 by friction welding, then the welded part is loosened by the clamp 6, and then the slide plate Ⅱ7 is driven forward and reset by the electric push rod Ⅱ15, thereby driving the clamp 6 to move forward and reset, and then the mobile platform 2 is controlled to drive the product 101 to move to the right, so as to adjust the position of the product 101, until the welded part on the product 101 is aligned with the center of the connecting tube 8, and then the slide plate Ⅱ7 and the connecting tube 8 are driven backward by the electric push rod Ⅱ15, thereby driving the rotating frame 9, the guide rod 10, the movable frame 11, the connecting plate 20, the sliding rod 12 and the grinding knife 13 to move backward. When the grinding knife 13 contacts the product 101, the product 101 will block the movement of the grinding knife 13 and the sliding rod 12. When the movable frame 11 When the connecting plate 20 continues to move backward, the spring 21 is compressed. Under the elastic force of the spring 21, the spring 21 will use its elastic force to squeeze the sliding rod 12 and the grinding knife 13, so that the grinding knife 13 is tightly attached to the surface of the product 101. Then, the movable frame 11 is driven by the electric push rod III 18 to move to the side close to the center of the connecting tube 8, thereby driving the sliding rod 12 and the grinding knife 13 to move to the side close to the center of the connecting tube 8, so that the grinding knife 13 gradually approaches the welding part on the product 101 until the grinding knife 13 contacts the outer wall of the welding part, and then the reduction motor 17 drives the rotating frame 9 to rotate, thereby driving the guide rod 10, the movable frame 11, the sliding rod 12 and the grinding knife 13 to rotate, so that the grinding knife 13 can remove the residual on the surface of the product 101. The product 101 is ground to remove the residue on the surface of the product 101. After the residue on the surface of the product 101 is completely removed, the electric push rod III 18 drives the movable frame 11 to move and reset to the side away from the center of the connecting tube 8, thereby driving the sliding rod 12 and the grinding knife 13 to move and reset to the side away from the center of the connecting tube 8, and then the electric push rod II 15 drives the slide plate II 7 and the connecting tube 8 to move forward and reset, thereby driving the rotating frame 9, the guide rod 10, the movable frame 11 and the connecting plate 20 to move forward and reset. During this period, the spring 21 gradually returns to its original state. When the spring 21 returns to its original state, the connecting plate 20 uses the spring 21 to pull the sliding rod 12 and the grinding knife 13 to move forward and reset, so that the grinding knife 13 is separated from the product 101. In this way,The welding piece can be welded to the surface of the product 101 by friction welding, and then the product 101 is removed from the mobile platform 2, and the mobile platform 2 is controlled to drive the product 101 to move to the left and reset.

[0034] See also Figure 6 and Figure 7 As shown, it also includes a limiting mechanism, which includes a cylinder 22 and a friction plate 23; the cylinder 22 is installed inside the movable frame 11; the friction plate 23 is connected to the telescopic rod of the cylinder 22, and the friction plate 23 is driven by the cylinder 22 to move to contact the sliding rod 12, so that the friction plate 23 can limit the sliding rod 12.

[0035] When the grinding knife 13 contacts the outer wall of the weldment, the friction plate 23 can be driven by the cylinder 22 to move toward the side close to the sliding rod 12 until the friction plate 23 contacts the sliding rod 12, so that the friction plate 23 limits the sliding rod 12 by friction force to prevent the sliding rod 12 from sliding in the movable frame 11 and affecting the grinding of the residue on the surface of the product 101 by the grinding knife 13; after the residue on the surface of the product 101 is removed, the friction plate 23 is driven by the cylinder 22 to move to the side away from the sliding rod 12 and reset, so that the friction plate 23 is separated from the sliding rod 12.

[0036] See also Figure 8 As shown, a blower mechanism is also included, which includes a connecting frame 24 and a fan 25; the connecting frame 24 is installed on the outer wall of the connecting tube 8; the fan 25 is installed on the upper side of the connecting frame 24, and the fan 25 is used to blow off the residue on the surface of the product 101.

[0037] When the grinding knife 13 is grinding the residue on the surface of the product 101 , the fan 25 can be used to blow air to the surface of the product 101 to blow off the residue from grinding on the surface of the product 101 , thereby preventing the residue from grinding from adhering to the surface of the product 101 .

[0038] See also Fig. 9 and Fig.10 As shown, a preheating mechanism is also included, which includes a support frame III 26 and a flamethrower 27; the support frame III 26 is installed on the top of the base plate 1, and the support frame III 26 is located on the rear side of the support frame I3; the flamethrower 27 is installed on the upper side of the support frame III 26, and the flamethrower 27 is used to preheat the surface of the product 101 by spraying fire.

[0039] When the mobile platform 2 drives the product 101 to move to the right, so that the position on the product 101 that needs to be welded is aligned with the welding part on the fixture 6, the flamethrower 27 can be started to spray fire on the position on the product 101 that needs to be welded (the temperature of the fire will not be higher than the melting point of the product 101, so as to prevent the temperature of the fire from causing the product 101 to melt), so as to preheat the position on the product 101 that needs to be welded (preheating can help reduce welding stress, control the cooling rate, improve the performance of the heat-affected zone, and prevent the formation of cold cracks. In addition, if the working environment temperature is low, preheating can also help maintain a more stable welding process) so that the subsequent product 101 and the welding part can be friction welded. After the position on the product 101 that needs to be welded is preheated, the flamethrower 27 can be turned off.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention.
