Description

Technical Field

[0001] The invention relates to the technical field of friction stir welding, in particular to horizontal friction welding equipment and a process thereof. Background Art

[0002] Friction stir welding is an advanced solid-phase connection technology. The basic principle is to insert a high-speed rotating stirring tool into the weld, and use the friction and stirring effect of the stirring tool to make the weld material in a thermoplastic state. The stirring tool moves forward along the weld, and the workpiece is welded under the drive of the high-speed rotation of the stirring tool. At present, the traditional friction stir welding shoulder rotates with the stirring needle, the friction heat is high, the heat input is large, and the longitudinal temperature gradient of the weld is large, resulting in large welding deformation. During the welding process, the plastic metal material is easy to overflow the weld area to form flash, resulting in weld thinning, and mechanical grinding is required after welding to remove the flash, which is time-consuming and laborious. In order to solve this problem, the existing technology uses a static shoulder friction stir welding tool to solve it. However, since the air can fully contact the workpiece during the stirring process of the stirring needle, the workpiece is oxidized in a high temperature environment, and the oxides mixed in will cause the weld to form S-line defects, thereby affecting the quality of friction welding. In order to reduce the mixing of oxides during the friction welding process of the stirring needle, the quality of friction welding can be improved. Summary of the invention

The protective ring 57 is slidably connected in the limited groove 561. The protective ring 57 is elastically connected to the surface of the limited groove 561 through a compression spring. A guide block 571 is fixedly connected to the outer wall of the protective ring 57. The guide block 571 is slidably connected to In the guide groove 562, when the protective ring 57 is squeezed and slides in the limit groove 561, the guide block 571 slides in the guide groove 562, so that the protective ring 57 moves stably, and the friction welding mechanism 5 is moved to the welding position of the workpiece through the X-axis moving mechanism and the Y-axis moving mechanism, so that the stirring needle 55 abuts against the workpiece, and then the motor is started, and the output shaft of the motor drives the transmission shaft 53 to rotate, and then drives the connecting ring 54 and the stirring needle 55 to rotate. The stirring needle 55 and the surface of the workpiece rub against each other to generate heat, and the stirring needle 55 gradually penetrates into the workpiece, and the protective ring 57 squeezes the compression spring. The protective ring 57 is tightly attached to the surface of the workpiece, and then the stirring needle 55 is driven to move by the X-axis moving mechanism and the Y-axis moving mechanism to realize the welding of the workpiece. The oxidation reaction of the stirring needle 55 with the heated workpiece during the friction welding process can be greatly reduced, the mixing of oxides can be reduced, and the quality of friction welding can be improved. At the same time, after the protective ring 57 squeezes the compression spring, the depth of the stirring needle 55 penetrating into the workpiece can be adjusted to ensure that the workpiece is stably welded.

A ball 584 is embedded on the top of the vertical rod 583. The piston ring 582 is elastically connected to the inner wall of the air chamber 581 by a return spring. The air chamber 581 is connected with a one-way nozzle 585 and a one-way filter inlet 586. The vertical rod 583 penetrates the inner wall of the connecting seat 52 and is slidably connected to the inner wall of the connecting seat 52. The nozzle 585 and the one-way filter inlet 586 both penetrate the outer wall of the connecting seat 52. There are four groups of jet assemblies 58, and the four groups of jet assemblies 58 are arranged in a circular array with the central axis of the stirring needle 55 as the symmetry axis. During the rotation of the connecting ring 54, the hemispherical protrusion 542 is driven to rotate. During this process, the hemispherical protrusion 542 squeezes the ball 584, and the vertical rod 583 descends to drive the piston ring 582 to compress the reset spring. After the hemispherical protrusion 542 passes through the ball 584, the reset spring drives the piston ring 582 to reset, so that the vertical rod 583 moves back and forth up and down, and then the outside air enters the air chamber 581 through the one-way filter inlet 586, and then is continuously ejected from the one-way nozzle 585, so that the dust generated on the surface of the workpiece during the fixing process is blown away, reducing the mixing of dust during the friction welding process, thereby improving the quality of subsequent friction welding.

The stirring needle 55 generates heat by friction with the surface of the workpiece, and the stirring needle 55 gradually penetrates into the workpiece. The protective ring 57 is in close contact with the surface of the workpiece. At the same time, the protective ring 57 squeezes the compression spring, and the guide block 571 slides in the guide groove 562. Then, the stirring needle 55 is driven to move by the X-axis moving mechanism and the Y-axis moving mechanism to achieve welding of the workpiece;

[0050] S4. The rotation of the connecting ring 54 drives the hemispherical projection 542 to rotate. The hemispherical projection 542 squeezes the ball 584 during the rotation. The vertical rod 583 descends and drives the piston ring 582 to compress the return spring. After the hemispherical projection 542 passes the ball 584, the return spring drives the piston ring 582 to return to its original position, so that the vertical rod 583 reciprocates up and down. Then, the outside air enters the air chamber through the one-way filter inlet 586, and then is continuously ejected from the one-way nozzle 585, so that the dust generated on the surface of the workpiece during the fixing process is blown away, thereby reducing the mixing of dust during the friction welding process.
