Description

Technical Field

[0001] The utility model relates to the technical field of workpiece welding, in particular to welding equipment with automatic feeding. Background Art

[0002] Automatic feeding welding equipment is a kind of welding equipment integrated with automation technology, which is mainly used to improve welding efficiency and reduce manpower input. The control system will set welding parameters such as welding current and welding time according to the requirements of the welding workpiece. The feeding system usually includes feeding device, transmission device and control system, which can accurately control the feeding speed and feeding amount to ensure the stability and consistency of the welding process. Automatic feeding welding equipment is also widely used in construction engineering, energy industry, steel industry and other fields for the manufacture and installation of steel structures, the construction and maintenance of oil and gas pipelines, the welding and manufacturing of steel plates and other processes.

[0003] For example, the Chinese patent "A welding device that is easy to use" with announcement number CN217371010U includes a base, a sliding rod is fixedly connected inside the base, two chassis are sleeved on the surface of the sliding rod, a first motor is embedded in the lower surface of the chassis, a gear is fixedly connected to the surface of the output shaft of the first motor, a toothed plate is fixedly connected inside the base, the toothed plate and the gear are meshed, two first movable grooves are symmetrically provided on the upper surface of the base, the bottoms of the two chassis respectively pass through the two first movable grooves and extend into the base; a second motor is fixedly connected inside the chassis, a threaded rod is fixedly connected to the surface of the output shaft of the second motor; a threaded nut is threadedly connected to the surface of the threaded rod, and a second movable groove is provided on the surface of the chassis; the threaded nut passes through the second movable groove and extends out of the chassis.

[0004] Although the above-mentioned prior art can realize welding of workpieces, in actual use, on the one hand, the loading of workpieces is not convenient enough. When welding the workpiece, the operator needs to hold the workpiece to perform welding operations, resulting in the operator needing to load the workpiece after the welding is completed, thereby increasing the workload of the operator. On the other hand, the movement of the electrode is not precise enough. When moving the electrode according to the size of the workpiece, the rocker needs to be turned to adjust the electrode, resulting in a certain distance error between the electrodes adjusted by the rocker, thereby reducing the welding quality of the workpiece. Therefore, it does not meet the existing needs. In this regard, we propose a welding device with automatic feeding. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model can automatically feed the welding device through the driving motor and the conveyor belt. When welding is required, the workpiece to be welded is placed on the conveyor belts on both sides, and then the driving motor is turned on, and the power supply directions of the driving motors on both sides are opposite, so that the output shaft of the driving motor drives the rotating rod to rotate, and the belt roller and the conveyor belt are driven by the rotating rod to move, so that the workpiece moves to the clamping table until the workpiece is transported to the center position of the clamping table and welded. After the welded workpiece is removed, the driving motor is turned on again to move the unwelded workpiece on the conveyor belt to the clamping table, simplifying the loading process of the workpiece, thereby improving the welding efficiency of the workpiece.

[0018] 3. The utility model can fix the workpiece during welding through the L-shaped fixing plate and the third hydraulic telescopic device. When the workpiece is welded, the workpiece is already located on the clamping table and the upper electrode and the lower electrode are moved to appropriate positions. The third hydraulic telescopic device is turned on to extend the telescopic end of the third hydraulic telescopic device. When the telescopic end of the third hydraulic telescopic device is extended, the L-shaped fixing plate fixedly connected thereto is driven to move. At this time, the L-shaped fixing plates on both sides move toward the center position of the clamping table until the rubber pad at the lower end of the horizontal plate of the L-shaped fixing plate contacts the surface of the workpiece, so that the workpiece is fixed on the clamping table through the L-shaped fixing plate, avoiding positional displacement of the workpiece during welding, thereby improving the welding effect of the workpiece.
