Obviously, the described embodiment is only a part of the embodiment of the practical embodiment, not all of the embodiments. Based on the embodiment in the practical embodiment, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this practical embodiment.

[0028] See also Figure 1-Figure 5 , this utility provides a technical solution:

[0029] Embodiment 1:

[0030] A double-station clamping welding device for a seat bracket assembly includes an operating table 1, a support arm 2 and a welding machine 3. The support arm 2 is fixedly installed on the top of the operating table 1, and the welding machine 3 is fixedly installed on one side of the support arm 2. A controller 4 is fixedly installed on one side of the operating table 1. Two workstations 5 are arranged on the top of the operating table 1. A clamp 24 is fixedly installed on the top of the workstations 5. Two adjustment mechanisms are arranged on the top of the operating table 1 to adjust the position of the workstations 5.

[0031] The cooling mechanism is fixedly arranged on the adjusting mechanism and can cool the seat bracket assembly after welding.

[0032] One implementation of the first embodiment is: the adjustment mechanism includes a hydraulic rod 6 fixedly arranged on the top of the operating table 1, and the output end of the hydraulic rod 6 is fixedly connected to one side of the workstation 5;

[0033] The top of the operating table 1 is fixedly connected with a housing 7, a screw rod 8 is arranged inside the housing 7, a moving block 9 is transmission-connected to the surface of the screw rod 8, two positioning rods 10 are fixedly connected to one side of the moving block 9, and a positioning hole 11 used in conjunction with the positioning rod 10 is opened on one side of the work station 5;

[0034] This embodiment takes into account the welding devices in the prior art. Usually, one welding machine 3 corresponds to one welding station. After welding, the seat bracket assembly needs to be cooled and removed before the next seat bracket assembly can be welded. This results in a long process cycle, thereby reducing the welding rate of the seat bracket assembly. Therefore, by setting an adjustment mechanism, after the welding of the seat bracket assembly on one of the workstations 5 is completed, the hydraulic rod 6 is started to drive the workstation 5 to slide along the track of the guide groove 23, and the workstation 5 will drive the seat bracket assembly fixed by the clamp 24. Leave the welding machine 3 position. At the same time, another hydraulic rod 6 is started to drive the seat bracket assembly fixed by the clamp 24 on another workstation 5 to move to the welding machine 3. Then, the twisting block 21 is rotated to make the screw rod 8 drive the moving block 9 and the limit block 18 to move along the track of the limit groove 19. At the same time, the moving block 9 drives the positioning rod 10 to enter the corresponding positioning hole 11 to lock the workstation 5 to avoid shaking during welding. At the same time, the welding machine 3 can weld the seat bracket assemblies on the two workstations 5 in turn, which greatly improves the welding speed.

[0035] The invention solves the problem that a welding device in the prior art usually has one welding machine 3 corresponding to one welding station, and after welding, the seat bracket assembly needs to be cooled and removed before the next seat bracket assembly can be welded, which results in a long process cycle and reduces the welding rate of the seat bracket assembly.

[0036] Preferably, both sides of the moving block 9 are fixedly connected to the limiting blocks 18, and the inner wall of the housing 7 is provided with limiting grooves 19 used in conjunction with the limiting blocks 18;

[0037] This embodiment can limit the moving trajectory of the moving block 9 by setting the limit block 18 and the limit groove 19. When the screw rod 8 rotates, the moving block 9 can only drive the limit block 18 to move along the trajectory of the limit groove 19, thereby playing a limiting role.

[0038] Preferably, a bearing 20 is provided at one end of the screw rod 8, and the screw rod 8 is rotatably connected to the inside of the housing 7 through the bearing 20. The end of the screw rod 8 away from the bearing 20 penetrates to one side of the housing 7 and is fixedly connected with a twisting block 21.

[0039] This embodiment provides a bearing 20 and a twisting block 21 to support the screw rod 8 and limit the screw rod 8 to rotation. The twisting block 21 can increase the contact area of ​​the finger to facilitate the user to rotate the screw rod 8 for transmission.

[0040] Preferably, two guide blocks 22 are fixedly connected to the bottom of the workstation 5, and a guide groove 23 for use with the guide blocks 22 is provided on the top of the operating table 1;

[0041] In this embodiment, by providing the guide block 22 and the guide groove 23 , the moving track of the workstation 5 can be limited, so that the workstation 5 can move more stably under the drive of the hydraulic rod 6 .

[0042] Embodiment 2:

[0043] On the basis of the first embodiment, the adjustment mechanism in this embodiment enables the welder 3 to weld the seat bracket assemblies on the two workstations 5 in turn, thereby improving the welding rate. However, considering that the seat bracket assembly needs to be removed and reinstalled after welding, and the surface temperature of the seat bracket assembly just after welding is high, it needs to wait for cooling before being removed, which reduces the welding rate. The cooling mechanism in this application includes a touch sensor 12 fixedly installed on one side of the hydraulic rod 6, and the touch sensor 12 is connected to the controller 4 by signal. Both sides of the operating table 1 are fixedly connected with an air collecting box 13, one side of the air collecting box 13 is fixedly connected with a blower 14, the top of the air collecting box 13 is fixedly connected with a transmission hose 15, and one side of the transmission hose 15 is fixedly connected with an air outlet hood 16;

[0044] This embodiment takes into account that the seat bracket assembly needs to be removed and reinstalled after welding, and the surface temperature of the seat bracket assembly just after welding is high, and it needs to wait for cooling before being removed, which reduces the welding rate. Therefore, by setting a cooling mechanism, when the hydraulic rod 6 drives the workstation 5 to leave the corresponding position of the welding machine 3, when the workstation 5 contacts the touch sensor 12, the touch sensor 12 will transmit a signal to the controller 4, and the built-in PLC module of the controller 4 will start the blower 14 to generate wind, which is sprayed through the air collecting box 13 by the transmission hose 15 and the air outlet hood 16 and blown on the seat bracket assembly to achieve the effect of removing heat and cooling.

[0045] The problem that the seat bracket assembly needs to be removed and reinstalled after welding is solved, while the surface temperature of the seat bracket assembly just after welding is high and needs to be cooled before removal, which reduces the welding rate.

[0046] Preferably, two electric telescopic rods 17 are fixedly connected to the top of the air collecting box 13, and the output ends of the electric telescopic rods 17 are fixedly connected to the bottom of the air outlet cover 16;

[0047] In this embodiment, the electric telescopic rod 17 is provided, and the air outlet cover 16 can be driven by the electric telescopic rod 17 to move up and down, so as to adjust the air outlet position and improve the cooling effect.

[0048] Working principle:

[0049] After the welding of the seat bracket assembly on one of the workstations 5 is completed, the hydraulic rod 6 is started to drive the workstation 5 to slide along the track of the guide groove 23, and the workstation 5 will drive the seat bracket assembly fixed by the clamp 24 to leave the position of the welding machine 3. At the same time, another hydraulic rod 6 is started to drive the seat bracket assembly fixed by the clamp 24 on another workstation 5 to move to the welding machine 3, and then the twisting block 21 is rotated to make the screw rod 8 drive the moving block 9 and the limit block 18 to move along the track of the limit groove 19. At the same time, the moving block 9 drives the positioning rod 10 to enter the corresponding positioning hole 11 to lock the workstation 5 to avoid shaking during welding. At the same time, the welding machine 3 can weld the seat bracket assemblies on the two workstations 5 in turn, which greatly improves the welding speed.

[0050] When the hydraulic rod 6 drives the work station 5 to leave the corresponding position of the welding machine 3, when the work station 5 contacts the touch sensor 12, the touch sensor 12 will transmit a signal to the controller 4. The built-in PLC module of the controller 4 will start the blower 14 to generate wind, which will be sprayed out through the air collecting box 13 by the transmission hose 15 and the air outlet hood 16 and blown onto the seat bracket assembly to achieve the effect of removing heat and cooling.

[0051] It should be noted that the welding machine 3, the controller 4, the hydraulic rod 6, the touch sensor 12, the blower 14 and the electric telescopic rod 17 are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art, and the specific composition and principle of the power supply of the welding machine 3, the controller 4, the hydraulic rod 6, the touch sensor 12, the blower 14 and the electric telescopic rod 17 are clear to those skilled in the art, so they will not be described in detail.
