Description

Technical Field

[0001] This invention relates to the field of automotive welding technology, specifically to an automatic welding device for automotive suspension brackets. Background Technology

[0002] Automotive suspension brackets are key structural components that connect the vehicle's powertrain (engine, transmission) or body to the chassis. Their core functions are to bear weight, isolate vibrations, and ensure vehicle stability.

[0003] Currently, automotive suspension brackets employ a structure where a base plate is welded to two L-shaped side plates. Before welding, the two L-shaped plates must be vertically placed at predetermined positions on either side of the base plate before welding.

[0019] This invention provides the following technical solutions: Example 1

[0020] Please see Figure 1 - Figure 7 An automatic welding device for automotive suspension brackets includes a work plate 1. A support block 2 and a motor 3 are fixedly connected to the lower side of the work plate 1. A rotating shaft 4 is rotatably connected to the upper side of the work plate 1. A limit unit 5 is provided at the upper end of the rotating shaft 4. The limit unit 5 includes a base plate 51, which is fixedly connected to the upper end of the rotating shaft 4. Two top blocks 52 are fixedly connected to the upper side of the base plate 51. A fixing plate 53 is fixedly connected to the outer side of the top blocks 52. A placement plate 54 is fixedly connected between the two fixing plates 53. A bottom beam 55 is provided on the upper side of the placement plate 54. Two connecting ears 56 are provided on the upper side of the bottom beam 55. A welding robot is installed on the work plate 1 to facilitate welding the two connecting ears 56 to a single bottom beam 55. During welding, the motor 3 is controlled, which drives the rotating shaft 4 to rotate. The rotating shaft 4 drives the limit unit 5 to rotate, which facilitates the rotation of the bottom beam 55 and the welding of the welding gun.

[0021] Both sides of the fixed plates 53 have a second sliding groove 517 on their outer sides. A second slider 518 is slidably connected to the inner side of the second sliding groove 517. A guide rail 521 is fixedly connected to the upper side of both sliders 518. A lifting block 522 is slidably connected to the inner side of the guide rail 521. A fixed cylinder 523 is fixedly connected to both the front and rear sides of the lifting block 522. A telescopic plate 524 is provided inside the fixed cylinder 523.

Rectangular grooves 528 are formed on the outer sides of the L-shaped plates 527. Linkage plates 529 are rotatably connected to the inner sides of the rectangular grooves 528 on both sides. Rotary blocks 530 are rotatably connected to the outer sides of the linkage plates 529. A control block 531 is fixedly connected to the upper side of the rotary blocks 530. An electric push rod 533 is fixedly connected between the lifting block 522 and the control block 531. A sliding rod 532 is fixedly connected to the upper side of the lifting block 522. The control block 531 and... The slide rod 532 is slidably connected, and a stabilizing plate 534 is fixedly connected to the upper end of the slide rod 532. An electric push rod 535 is fixedly connected between the inner wall of the guide rail 521 and the control block 531. When welding the connecting lug 56, the electric push rod 533 is first controlled to drive the control block 531 to rise. The control block 531 drives the linkage plate 529 to rotate. The linkage plate 529 drives the L-shaped plate 527 to move, so that the L-shaped plates 527 on both sides move closer to each other. The L-shaped plates 527 drive the telescopic plate 524 to move. The mounting block 525 moves, which in turn moves the clamping plate 526, bringing the clamping plates 526 closer together. This allows the clamping plates 526 to limit the connection ears 56. At this time, the electric push rod 535 controls the stabilizing plate 534 to descend, which in turn causes the sliding rod 532 to descend. The sliding rod 532 then causes the lifting block 522 to descend, which in turn causes the connection ears 56 on the clamping plate 526 to descend, making the connection ears 56 on both sides in close contact with the bottom beam 55, thus increasing the stability of the connection ears 56 during welding.

[0022] Two sliding grooves 58 are provided on the upper side of the placement plate 54. A slider 59 is slidably connected to the inner side of the sliding groove 58.

A T-shaped plate 515 is fixedly connected to the right side of the rotating block 514. A drive is fixedly connected to the upper side of the base plate 51. Before welding, the electric push rod 516 moves the T-shaped plate 515. The bottom beam 55 is placed on the placement plate 54. Then, the electric push rod 516 moves the T-shaped plate 515. The T-shaped plate 515 moves the inclined plate 513. The inclined plate 513 moves the bottom block 512, so that the bottom blocks 512 on both sides are closer to each other. The bottom block 512 moves the slider 59. The slider 59 moves the rectangular plate 510. The rectangular plate 510 moves the correction plate 511, so that the correction plates 511 on both sides are closer to each other. This makes it easier for the correction plates 511 to limit the bottom beam 55 and prevent the bottom beam 55 from shaking.

[0023] Both sides of the slider 518 are fixedly connected to the lower side of the movable block 519. The two sides of the top block 52 are rotatably connected to the bidirectional screw 520. The two ends of the bidirectional screw 520 are provided with opposite threads. The two ends of the bidirectional screw 520 are respectively threaded to the two sides of the movable block 519. The top block 52 is fixedly connected to the outer side of the motor 57. When the motor 57 is started, the motor 57 drives the bidirectional screw 520 to rotate. The bidirectional screw 520 drives the movable block 519 to move. The movable block 519 drives the slider 518 to move. The slider 518 drives the guide rail 521 to move, so that the connecting ears 56 on both sides are brought closer to each other, so that the connecting ears 56 can be placed in the corresponding welding position.

Two top blocks 52 are fixedly connected to the upper side of the base plate 51. A fixing plate 53 is fixedly connected to the outer side of the top blocks 52. A placement plate 54 is fixedly connected between the two fixing plates 53. A bottom beam 55 is provided on the upper side of the placement plate 54. Two connecting ears 56 are provided on the upper side of the bottom beam 55. A welding robot is installed on the work plate 1 to facilitate welding the two connecting ears 56 to a single bottom beam 55. During welding, the motor 3 is controlled, which drives the rotating shaft 4 to rotate. The rotating shaft 4 drives the limiting unit 5 to rotate, which facilitates the rotation of the bottom beam 55 and the welding of the welding gun.

Rotary blocks 530 are rotatably connected to the outer sides of the linkage plates 529. A control block 531 is fixedly connected to the upper side of the rotary blocks 530. An electric push rod 533 is fixedly connected between the lifting block 522 and the control block 531. A sliding rod 532 is fixedly connected to the upper side of the lifting block 522.

When welding the connecting lug 56, the electric push rod 533 is first controlled to drive the control block 531 to rise. The control block 531 drives the linkage plate 529 to rotate. The linkage plate 529 drives the L-shaped plate 527 to move, so that the L-shaped plates 527 on both sides move closer to each other. The L-shaped plates 527 drive the telescopic plate 524 to move. The mounting block 525 moves, which in turn moves the clamping plate 526, bringing the clamping plates 526 closer together. This allows the clamping plates 526 to limit the connection ears 56. At this time, the electric push rod 535 controls the stabilizing plate 534 to descend, which in turn causes the sliding rod 532 to descend. The sliding rod 532 then causes the lifting block 522 to descend, which in turn causes the connection ears 56 on the clamping plate 526 to descend, making the connection ears 56 on both sides in close contact with the bottom beam 55, thus increasing the stability of the connection ears 56 during welding.

[0026] Two sliding grooves 58 are provided on the upper side of the placement plate 54. A slider 59 is slidably connected to the inner side of the sliding groove 58. A rectangular plate 510 is fixedly connected to the upper side of the slider 59. A correction plate 511 is fixedly connected to the side of the rectangular plate 510 near the bottom beam 55.

A T-shaped plate 515 is fixedly connected to the right side of the rotating block 514. A drive is fixedly connected to the upper side of the base plate 51. Before welding, the electric push rod 516 moves the T-shaped plate 515. The bottom beam 55 is placed on the placement plate 54. Then, the electric push rod 516 moves the T-shaped plate 515. The T-shaped plate 515 moves the inclined plate 513. The inclined plate 513 moves the bottom block 512, so that the bottom blocks 512 on both sides are closer to each other. The bottom block 512 moves the slider 59. The slider 59 moves the rectangular plate 510. The rectangular plate 510 moves the correction plate 511, so that the correction plates 511 on both sides are closer to each other. This makes it easier for the correction plates 511 to limit the bottom beam 55 and prevent the bottom beam 55 from shaking.

[0027] Both sides of the slider 518 are fixedly connected to the lower side of the movable block 519. The two sides of the top block 52 are rotatably connected to the bidirectional screw 520.
