In this embodiment, the comb-tooth steel plate 11 is fixedly connected to the pressure platform 2 by screws 111. In this embodiment, the comb-tooth steel plate 11 is provided with a through mounting hole 112, and the pressure platform 2 is provided with a threaded hole. The screw 111 is slid through the mounting hole 112 and then threadedly embedded in the threaded hole. Preferably, the two comb-tooth steel plates 11 can be positioned by a positioning substrate to facilitate the fixing of the screw 111. The dustproof plate 12 is folded to provide a positioning piece for positioning the buffer 13 and the water guide groove 14 .

[0037] Pressure plates 4 are respectively arranged on both sides of the assembly platform 1, and both ends of the pressure plates 4 are connected to the assembly platform 1 through hydraulic cylinders 41. A flip shaft 31 is fixedly arranged on one side of the pressure platform 3, and both ends of the flip shaft 31 are rotatably connected to the two pressure plates 4, and the flip shaft 31 is driven by a flip motor 311 so that the pressure plate 4 can be flipped onto the pressure platform 2.

[0038] Two fixed plates 32 are arranged on one side of the pressurizing platform 3, and a clamp for clamping the fin plate 15 and the connecting plate 16 is arranged on one side of the fixed plate 3 facing away from the pressurizing platform 3. The fin plate 15 and the connecting plate 16 are welded to form a wing member. After the pressurizing platform 3 is flipped over, it is pressed toward the pressure platform 2 by the hydraulic cylinder 41. The wing member of one fixed plate 32 can be pressed toward the buffer member 13, the water guide groove 14 and the corresponding comb tooth steel plate 11, and the wing member of the other fixed plate 32 can be pressed toward the dustproof plate 12 and the corresponding comb tooth steel plate 11. By welding one wing member to the water guide groove 14 and the corresponding comb tooth steel plate 11, and welding the other wing member to the dustproof plate 12 and the corresponding comb tooth steel plate 11, an expansion joint component is formed.

[0039] In this embodiment, after fixing two comb-tooth steel plates 11 on the pressure platform 2, the dust-proof plate 12 is welded to the two comb-tooth steel plates 11 to close the gap between the two comb-tooth steel plates 11, the buffer pad 131 is placed on one side of the dust-proof plate 12, and then the buffer member 13 is covered on the buffer pad 131, and the water guide groove 14 is welded to one side of the buffer member 13, so that the buffer member 13 and the water guide groove 14 are located above a comb-tooth steel plate 11; the fin plate 15 and the connecting plate 16 are fixed to the fixing plate 32 by a clamp and then welded into a fin member; The flip motor 311 is used to drive the flip shaft 31, so that the pressure platform 3 is flipped and pressed against the pressure platform 2. At the same time, the wing of a fixed plate 32 is pressed against the buffer 13, the water guide groove 14 and the corresponding comb steel plate 11, and the wing of another fixed plate 32 is pressed against the dust plate 12 and the corresponding comb steel plate 11. By welding one wing to the corresponding comb steel plate 11, and welding the other wing to the dust plate 12 and the corresponding comb steel plate 11, an expansion joint component is formed. Under the elastic force of the buffer pad 131, the buffer 13 and the water guide groove 14 can abut against the corresponding wing. After releasing the clamp, the pressure platform 3 is reset by the flip motor 311, and the expansion joint component can be moved out of the assembly platform 1 by a crane.

[0040] In this embodiment, the two sides of the two comb-tooth steel plates 11 facing away from the wing member are connected by a connecting frame, and the two ends of the connecting frame are connected to the two comb-tooth steel plates 11 by screws and nuts respectively.

[0041] Since the buffer 13 and the water guide groove 14 are clamped between the dustproof plate 12 and the wing, under the elastic force of the buffer pad 131, the buffer 13 and the water guide groove 14 can abut against the corresponding wing, ensuring that the expansion joint component has a certain elasticity and reducing the noise generated when the vehicle passes.

[0042] This embodiment can manufacture expansion joint components at one workstation, effectively improving the production efficiency of the expansion joint components. In addition, the present invention can reduce the frequency of hoisting of parts and effectively avoid the occurrence of safety accidents.

[0043] like Figure 3 and Figure 4 As shown, the clamp includes a first clamp and a second clamp, and a plurality of first clamps are alternately arranged along the axial direction of the flip axis 31, and the first clamp includes a first abutment member 511 and a first clamping member 512, and the first abutment member 511 and the first clamping member 512 are both perpendicular to the flip axis 31, the first abutment member 511 is fixedly connected to the fixed plate 32, the first clamping member 512 is slidably connected to the fixed plate 32, and the first clamping member 512 on the fixed plate 32 is driven by the first telescopic cylinder 531, so that the fin plate 15 can be clamped between the first abutment member 511 and the first clamping member 512.

[0044] The second clamp is located at one side of the fixed plate 32, and includes a second abutting member 521 and a second clamping member 522. The second abutting member 521 and the second clamping member 522 are both parallel to the flip axis 31. The second abutting member 521 is fixedly connected to the fixed plate 32, and the second clamping member 522 is slidably connected to the fixed plate 32. The second clamping member 522 is driven by the second telescopic cylinder 532 so that the connecting plate 16 can be clamped between the second abutting member 521 and the second clamping member 522, and one side of the connecting plate 16 abuts against one end of the fin plate 15.

[0045] The first clamp and the second clamp of the two fixing plates 32 are arranged in a mirror image, and the second clamp is located in the middle of the pressurizing platform 3 .

[0046] A first driving rod 541 and a second driving rod 542 are provided on a side of the fixing plate 32 facing the pressurizing platform 3.

[0047] The first driving rod 541 is slidably connected to the fixed plate 32, and the output shaft of the first telescopic cylinder 531 is transmission-connected to the first driving rod 541, so that the first driving rod 541 moves along the axial direction of the flip shaft 31; the fixed plate 32 is provided with first sliding grooves 321, and the number of the first sliding grooves 321 and the first clamping member 512 is the same, and the bottom of the first clamping member 512 is fixedly connected to the first driving rod 541 through the first sliding grooves 321, so that under the drive of the first telescopic cylinder 531, the first clamping member 512 can move toward or away from the first abutting member 511;

[0048] The second driving rod 542 is slidably connected to the fixed plate 32, and the output shaft of the second telescopic cylinder 532 is transmission-connected to the second driving rod 542, so that the second driving rod 542 moves in a direction perpendicular to the flip axis 31; the fixed plate 32 is penetrated by a second slide groove 322, and the bottom of the second clamping member 522 is fixedly connected to the second driving rod 542 through the second slide groove 322, so that under the drive of the second telescopic cylinder 532, the second clamping member 522 can move toward or away from the second clamping member 522. The first telescopic cylinder 531 and the second telescopic cylinder 532 of this embodiment are both controlled by the same hydraulic pump.

[0049] Under the action of the second telescopic cylinder 532, the second driving rod 542 drives the second clamping member 522 to press against the second abutting member 521, so that the connecting plate 16 can be clamped and fixed on the pressurizing platform 3; under the action of the first telescopic cylinder 531, the first driving rod 541 moves, so that the first clamping member 512 can press against the first abutting member 511, thereby clamping the fin plate 15, and at the same time, one end of the fin plate 15 abuts against one side of the connecting plate 16, and the fin plate 15 and the connecting plate 16 are welded to form a wing member. This embodiment can quickly position and weld the fin plate 15 and the connecting plate 16 without manual positioning by workers, which increases the accuracy of welding the fin plate 15 and the connecting plate 16, and improves the production efficiency of the wing member.

[0050] like Figure 3 and Figure 4 As shown, the fixed plate 32 away from one end of the flip axis 31 is an adjustment plate, which is slidably connected to the pressurizing platform 3 through a slide rail 8. A number of adjustment holes 81 are respectively provided on both sides of the adjustment plate, and the pressurizing platform 3 is provided with a positioning hole 82. The positioning hole 82 is provided with a positioning bolt 83. The positioning bolt 83 can be slidably passed through different adjustment holes 81 and then threadedly embedded in the positioning hole 82 to adjust the distance between the two fixed plates 32.

[0051] Since the adjustment plate is provided with a plurality of adjustment holes 81 , the spacing between the two fixing plates 32 can be adjusted by sliding the positioning bolts 83 through different adjustment holes 81 and then threading them into the positioning bolts 83 , thereby manufacturing wing members of different specifications.

[0052] like Figure 1 and Figure 5 As shown, each pressure plate 4 is provided with an anti-warping mechanism, which is used to limit the warping of the pressure platform 3 away from the flip axis 31 when the hydraulic cylinder 41 is pressurized. The anti-warping mechanism is located at the end of the pressure plate 4 away from the flip axis 31, and the anti-warping mechanism includes a fixed shell 6, a limiter 61 and a drive motor 62.

[0053] A support rod 64 and a threaded rod 65 are provided in the fixed shell 6.

[0054] In this embodiment, the output shaft of the driving motor 62 is provided with a first gear 621, and the end of the threaded rod 65 away from the limiting member 61 is fixedly sleeved with a second gear 622. The driving motor 62 drives the second gear 622 to rotate through the first gear 621, thereby driving the threaded rod 65. Under the drive of the threaded rod 65, the slider 63 moves along the support rod 64, so that the limiting member 61 can pass through the fixed shell 6 or retract into the fixed shell 6.

[0055] When the pressurizing platform 3 flips over to the pressure-bearing platform 2, the driving motor 62 drives the slider 63 to move, so that the limit member 61 can pass through the outside of the fixed shell 6. When the hydraulic cylinder 41 drives the pressurizing plate 4 to descend, the limit member 61 can limit the end of the pressurizing platform 3 away from the flipping axis 31, thereby avoiding the edge warping of the pressurizing platform 3 and ensuring that the pressurizing platform 3 can effectively compress the buffer pad 131.

[0056] like Figure 1 and Figure 6 As shown, the assembly platform 1 is fixedly provided with a bracket 7, and the bracket 7 is provided with a first infrared sensor 71 and a second infrared sensor 72 in sequence along the height direction. The first infrared sensor 71 and the second infrared sensor 72 are electrically connected to the controller, and the first infrared sensor 71 is used to sense whether the pressurizing platform 3 is reversed in place, and the second infrared sensor 72 is used to sense whether the pressurizing plate 4 is pressed down in place. The controller of this embodiment is electrically connected to the flipping motor 311 and the hydraulic cylinder 41. When the controller obtains the signal of the first infrared sensor 71, the controller controls the flipping motor 311 to stop, and then controls the hydraulic cylinder 41 to shorten, so that after the pressurizing platform 3 is flipped in place, the pressurizing plate 4 applies downward pressure to the pressurizing platform 3.

[0057] like Figure 5 As shown, the first travel switch 661 and the second travel switch 662 are fixedly arranged on the inner walls of the fixed shell 6 along the moving direction of the slider 63, and the slider 63 can press the first travel switch 661 or the second travel switch 662. The first travel switch 661 and the second travel switch 662 are electrically connected to the drive motor 62 through the controller. After the controller obtains the signal of flipping into place through the first infrared sensor 71, the controller controls the drive motor 62 to rotate so that the limit member 61 passes through the fixed shell 6. The controller of this embodiment is a PLC controller.

[0059] After fixing the two comb-tooth steel plates 11 on the pressure platform 2, weld the dustproof plate 12 to the two comb-tooth steel plates 11 to close the gap between the two comb-tooth steel plates 11, place the buffer pad 131 on one side of the dustproof plate 12, and then cover the buffer 13 on the buffer pad 131, weld the water guide groove 14 to one side of the buffer 13, and make the buffer 13 and the water guide groove 14 be located above a comb-tooth steel plate 11, weld the buffer 13 and the water guide groove 14 to each other, and weld the side of the water guide groove 14 away from the buffer 13 to the corresponding comb-tooth steel plate 11.

[0060] The connecting plate 16 is clamped between the second clamping member 522 and the second abutment member 521 by the second telescopic cylinder 532, and the fin plate 15 is clamped between the first clamping member 512 and the first abutment member 511 by the first telescopic cylinder 531. At the same time, one end of the fin plate 15 abuts against one side of the connecting plate 16, and the fin plate 15 and the connecting plate 16 are welded to form a fin.

[0061] The fin plate 15 and the connecting plate 16 are fixed to the fixing plate 32 by a clamp and then welded to form a fin member.

[0062] The flip motor 311 is used to drive the flip shaft 31, so that the pressure platform 3 is flipped and pressed against the pressure platform 2. At the same time, the wing of one fixed plate 32 is pressed against the buffer 13, the water guide groove 14 and the corresponding comb tooth steel plate 11, and the wing of the other fixed plate 32 is pressed against the dustproof plate 12 and the corresponding comb tooth steel plate 11.

[0063] When the controller obtains the signal of the first infrared sensor 71, the controller controls the flip motor 311 to stop, and at the same time controls the drive motor 62 to rotate, so that the limiter 61 passes through the fixed shell 6. When the slider 63 presses the first stroke switch 661, it proves that the limiter 61 is extended to the right position, and the controller controls the drive motor 62 to stop. After the controller obtains the signal of the first stroke switch 661, the controller controls the hydraulic cylinder 41 to shorten, so that the wing member and the comb-tooth steel plate 11 are in a compressed state, and one wing member is welded to the corresponding comb-tooth steel plate 11, and the other wing member is welded to the dust plate 12 and the corresponding comb-tooth steel plate 11 to form an expansion joint component.

[0064] After welding is completed, the controller controls the driving motor 62 to rotate. When the slider 63 presses the second travel switch 662, it proves that the limiter 61 is retracted into place, and the controller controls the driving motor 62 to stop. After the controller obtains the signal of the second travel switch 662, the controller controls the first telescopic cylinder 531, the second telescopic cylinder 532, and the hydraulic cylinder 41 to reset. When the second infrared sensor 72 obtains the change signal, the controller controls the flip motor 311 to rotate, so that the pressurizing table 3 is reset.
