[0004] As shown in the above technology, the welding station is used to weld the workpiece. During welding, the workpiece is fixed on the displacement mechanism, so it is necessary to ensure that the position of the workpiece is fixed and stable. In the existing welding workstation, the workpiece is fixed by a clamp. However, when facing the rear support of different sizes, the clamp uses the same clamping block for clamping, which may lead to insufficient clamping stability and the workpiece may move during the welding process. Utility Model Content

[0008] Preferably, the quick-change assembly includes two sets of fixed seats, one upper and one lower, which are fixedly connected to the top and bottom of the push rod, respectively. Each set of fixed seats consists of two fixed seats, one on the left and one on the right, and a middle rod is fixedly connected between each set of fixed seats. A limit plate is rotatably connected to the surface of the middle rod.

[0009] Preferably, a torsion spring is fitted on the surface of the intermediate rod inside the limiting plate, one end of the torsion spring is fixedly connected to the surface of the intermediate rod, and the other end of the torsion spring is fixedly connected to the limiting plate.

[0010] Preferably, one end of the push rod has a slot, and one side of the clamping block is fixedly connected to an insert rod. The top and bottom of the insert rod are provided with positioning grooves, and the end of the limiting plate enters the positioning groove to fix the position of the clamping block.

[0011] Preferably, the quick-release clamp further includes a pushing component, wherein the push rod is used to drive the push rod to move back and forth, and the movement of the push rod drives the clamping block to move.

[0012] Preferably, the support assembly includes a back plate, which is fixedly connected to the top of the workbench. A main positioning pin is fixedly connected to the front of the back plate. The back plate has two rows of threaded holes on the left and right sides inside, and multiple push rods are threadedly connected to the inner surface of the threaded holes.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 The rear support welding workstation offers two technical solutions:

[0024] The first implementation: The rear support welding workstation includes a support platform 1, a welding robot 2 and a control box 8. Two positioners 3 are fixedly installed on the top of the support platform 1, and the rotating shafts of the two positioners 3 are fixedly connected to the worktable 4. A clamping and stabilizing mechanism is provided on the worktable 4. The clamping and stabilizing mechanism includes a quick push clamp 5 and a support component 6.

[0025] The quick-release push clamp 5 is used to push the rear support workpiece to move and is clamped by the support assembly 6. The quick-release push clamp 5 includes a base 51 and a sleeve 52. The base 51 is fixedly connected to the top of the worktable 4. The sleeve 52 is fixedly connected to the top of the base 51. A push rod 53 is slidably connected to one end of the sleeve 52. The push rod 53 is equipped with a quick-release clamping block 54 through the quick-change assembly 7. The clamping block 54 is equipped with different sizes. The quick-release push clamp 5 also includes a pushing component 55. The push rod 53 is used to drive the push rod 53 to move back and forth. The movement of the push rod 53 drives the clamping block 54 to move.

[0026] The quick-change assembly 7 includes two sets of fixing seats 71, one upper and one lower. The two sets of fixing seats 71 are fixedly connected to the top and bottom of the push rod 53, respectively. Each set of fixing seats 71 consists of two left and right fixing seats 71, and a middle rod 72 is fixedly connected between each set of fixing seats 71. A limiting plate 73 is rotatably connected to the surface of the middle rod 72. A torsion spring 74 is sleeved on the surface of the middle rod 72 inside the limiting plate 73. One end of the torsion spring 74 is fixedly connected to the surface of the middle rod 72, and the other end of the torsion spring 74 is fixedly connected to the limiting plate 73. A slot 75 is opened at one end of the push rod 53. An insertion rod 76 is fixedly connected to one side of the clamping block 54. The top and bottom of the insertion rod 76 are both opened with positioning grooves 77. The end of the limiting plate 73 enters the positioning groove 77 to fix the position of the clamping block 54.

[0027] When welding rear support workpieces of different sizes, the quick-change component 7 can quickly replace the clamping block 54 to match the size of the rear support workpiece, thereby achieving a better clamping and fixing effect and improving the practicality of the device.

[0028] The second embodiment differs from the first embodiment in that the support component 6 includes a backing plate 61, which is fixedly connected to the top of the workbench 4. A main positioning pin 62 is fixedly connected to the front of the backing plate 61. The backing plate 61 has two rows of threaded holes 63 on the left and right sides inside, and multiple push rods 64 are threadedly connected to the inner surface of the threaded holes 63.

[0029] The workpiece is clamped by the support assembly 6, which is equipped with a main positioning pin 62 and a push rod 64. The position of the push rod 64 can be adjusted to limit the workpiece of different sizes and prevent the workpiece from tilting.

[0030] In use, the workpiece is placed between the clamping block 54 and the main positioning pin 62. The clamping block 54 is moved closer to the workpiece by the pushing component 55, thereby clamping and fixing it. In addition, when clamping workpieces of different sizes, the two limiting plates 73 are pressed at the same time, so that the ends of the limiting plates 73 come out of the positioning grooves 77. At this time, the clamping block 54 can be removed and replaced with a clamping block 54 of another size. During installation, the insert rod 76 on the clamping block 54 is inserted into the slot 75. The end of the insert rod 76 contacts the limiting plate 73 and pushes the limiting plate 73 to rotate. After the positioning groove 77 is aligned with the end of the limiting plate 73, the end of the limiting plate 73 enters the positioning groove 77 under the action of the torsion spring 74, thereby fixing the position of the clamping block 54.
