[0006] The utility model discloses a technical scheme for a welding machine with a pressing device, comprising a workbench, a mounting frame, a positioning rod, a lifting plate, a slide rod, a limiting sheet, a spring, a pressing plate, a fixed strip, a clamping strip and a fixing bolt, a welding module is arranged at the middle position of the rear surface of the workbench, a moving assembly is arranged at the rear side of the upper surface of the workbench, a connecting plate is arranged at the moving end of the moving assembly, a mounting frame is arranged on the upper surface of the connecting plate, a positioning rod is arranged on the inner surface of the mounting frame at both sides, a lifting plate is slidably connected to the outer surface of the positioning rod, five slide rods with equal intervals are slidably connected to the upper surface of the lifting plate away from the corresponding mounting frame, a limiting sheet is arranged on the top surface of the slide rod, a spring is arranged on the outer surface of the slide rod at the lower side of the lifting plate, a pressing plate is arranged on the bottom surface of the slide rod, the bottom surface of the spring is connected to the upper surface of the pressing plate, a fixed strip is fixed to the upper surface of the lifting plate at the side position of the slide rod, a clamping strip is arranged at one side of the fixed strip, and two fixing bolts symmetrically arranged at the other side of the fixed strip are used to fix the fixed strip and the clamping strip.

[0007] Preferably, the spring is arranged to contact the workpiece surface when the lifting plate is lowered, and each pressing plate is driven to move upwards and the spring is contracted when each pressing plate is blocked by the workpiece. Then, the fixing bolt can be tightened to fix the slide rod by the fixed strip and the clamping strip, so as to avoid the slide rod from sliding up and down. The limiting sheet is arranged to avoid the slide rod from falling off, so as to achieve flexible positioning of the irregular workpiece. Thus, the problem that the pressing structure of the existing welding machine with a pressing device cannot be flexibly stretched and contracted when in use, so that the irregular workpiece cannot be tightly attached to the workpiece when being pressed, resulting in an undesirable positioning effect, is solved.

[0008] Preferably, the moving assembly comprises a fixed frame, a first driving motor, a bidirectional screw rod and a moving seat. The fixed frame is arranged on the rear side of the upper surface of the workbench, the first driving motor is arranged on the right side surface of the fixed frame, the output end of the first driving motor is connected to the bidirectional screw rod through the right side surface of the fixed frame, the outer surface of the bidirectional screw rod is threadedly connected to two symmetrical moving seats, and the front side surface of the moving seat is connected to the rear side surface of the connecting plate.

[0012] Preferably, cylinders are embedded in the bottom surface of the workbench at the side of the casters, and gaskets are provided at the extension and retraction ends of the cylinders.

[0013] Preferably, the front surface of the workbench has several equally spaced heat dissipation grooves.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting springs, multiple pressure plates will contact the workpiece surface when the lifting plate descends. Each pressure plate will cause the slide rod to move upward and the spring to contract when it is blocked by the workpiece. Then the fixing bolts can be tightened so that the fixing strip and clamping strip clamp and fix the slide rod to prevent it from sliding up and down. The setting of the limit plate can prevent the slide rod from falling off. This achieves flexible positioning of irregular workpieces, thus solving the problem that the existing welding machine with clamping device cannot flexibly extend and retract when using its clamping structure, which makes it impossible to fit tightly with the workpiece when clamping irregular workpieces, resulting in unsatisfactory positioning effect.
