[0024] Example
[0025] To address the problems existing in the current technology of riveting equipment for riveting the shafts and press-fit parts of HINGE components, reference is made to... Figure 1 and Figure 2 As shown, this application discloses a laser welding machine, including a stage 10, a rotary clamping mechanism 20 and a welding mechanism 30;
[0026] The rotary clamping mechanism 20 includes a movable chuck 21 and a rotary chuck 22 that cooperate with the movable chuck 21 on both sides of the platform 10 in the X-axis direction. With the cooperation of the movable chuck 21 and the rotary chuck 22, the workpiece to be welded can be clamped and the workpiece to be welded can be driven to rotate.
[0027] The welding mechanism 30 includes an XY axis drive assembly 31 disposed on one side of the platform 10 in the Y-axis direction and a laser welding assembly 32 connected to the XY axis drive assembly 31. Under the drive of the XY axis drive assembly 31, the laser welding assembly 32 can perform spot welding on the workpiece.
[0028] In actual use, the operator first assembles the rotating shaft and the pressing component and places them between the moving chuck 21 and the rotating chuck 22. The XY axis drive assembly 31 is controlled to drive the laser welding assembly 32 to move along the X and Y axes. At this time, the laser welding assembly 32 can spot weld the assembled rotating shaft and pressing component. During this process, the rotating chuck 22 and the moving chuck 21 cooperate to drive the assembled rotating shaft and pressing component to rotate.
[0029] Based on the above solution, the final product obtained by this application avoids material damage and improves material strength compared to the product obtained after riveting by riveting equipment. It also solves the problems of uneven stress distribution causing the rotating shaft and the pressed part to have an angle and inconsistent angle direction, as well as instability.
[0030] In one specific embodiment, the movable chuck 21 of this application includes a base 211 disposed on the platform 10, a manually adjustable slide 212 disposed on one side of the base 211, an L-shaped support 213 connected to the manually adjustable slide 212, and a first pressure head 214 passing through the L-shaped support 213. It should be noted that the manually adjustable slide 212 of this application should be a commercially available manually adjustable slide 212 with a clamping function. Under the drive of the manually adjustable slide 212, the L-shaped support 213 moves toward the rotating chuck 22.
[0031] The rotating chuck 22 includes a bearing seat 221 on the platform 10, a servo motor 223 located outside the bearing seat 221 and integrally connected to a reducer 222, a rotating chuck 224 located inside the bearing seat 221 and connected to the drive shaft of the reducer 222, a shaft body 225 connected to the rotating chuck 224, and a second pressure head 227 connected to the shaft body 225 via a coupling 226. With the cooperation of the first pressure head 214 and the second pressure head 227 on the L-shaped support 213, the assembled rotating shaft and pressing parts can be clamped. During the laser welding process driven by the XY axis drive assembly 31 and the laser welding assembly 32, the servo motor 223 will cooperate with the reducer 222, the chuck and the coupling 226 to drive the second pressure head 227 to select, thereby causing the fixed rotating shaft and pressing parts to rotate as a whole.
[0032] In order to make the first pressure head 214 rotate smoothly, this application also provides a support plate 228 on the other side of the base 211. The second pressure head 227 is rotatably mounted on the support plate 228. During the spot welding process of the laser welding assembly 32, the second pressure head 227 of this application will rotate on the support plate 228.
[0033] In one specific embodiment, the XY axis drive assembly 31 of this application includes an X-axis servo linear module 311 on the platform 10, a Y-axis servo linear module 312 connected to the X-axis servo linear module 311, and a carrier 313 connected to the Y-axis servo linear module 312. The laser welding assembly 32 includes a transverse support 321 connected to the carrier 313 and a laser welding head 322 fixed to the transverse support 321. Under the cooperative drive of the X-axis servo linear module 311 and the Y-axis servo linear module 312, the laser welding head 322 located on the carrier 313 will realize the movement of the X-axis and Y-axis, thereby spot welding the assembled rotating shaft and pressing parts.
[0034] In addition to the above structure, this application also provides a visual inspection camera 323 on the transverse support 321. When the laser welding assembly 32 completes the spot welding of the assembled rotating shaft and press-fit parts, the visual inspection camera 323 will inspect the welding quality.
