Technical Field

[0001] The present application relates to the field of steel grating welding processing equipment, and in particular to a steel grating welding processing equipment. Background Art

[0002] At present, steel grating is a widely used industrial material. It has been widely used in construction, chemical industry, transportation and other fields because of its good load-bearing capacity and corrosion resistance. In order to improve production efficiency and product quality, automated welding equipment has gradually become the mainstream choice of the industry. These equipment can not only significantly increase the welding speed, but also ensure the quality consistency of the weld and reduce the errors caused by manual operation. However, with the continuous growth of market demand and the advancement of technology, the existing steel grating welding processing equipment still has certain limitations in adapting to complex workpieces and high-precision requirements.

[0003] At present, the commonly used steel grating welding processing equipment mainly includes manual welding workstations, semi-automatic welding machines and fully automatic welding production lines. Manual welding workstations mainly rely on manual operation by workers, which is highly flexible but inefficient; semi-automatic welding machines are usually equipped with simple fixtures and a single welding head, which can improve welding efficiency to a certain extent, but still require more manual intervention; and although fully automatic welding production lines have a high degree of automation and can achieve continuous production and multi-point synchronous welding, their complex structure, high cost, and harsh environmental requirements limit their scope of application.

[0004] In the above-mentioned prior art, whether it is manual welding or semi-automatic welding equipment, it is difficult to achieve efficient and accurate multi-point simultaneous welding during the welding process, especially when processing longer steel gratings, the welding quality and stability are easily affected. In addition, the existing fixing device and guide device design are often too simple to effectively cope with steel gratings of different specifications and shapes, resulting in inaccurate welding paths and affecting the quality of the final product. Therefore, it is urgent to develop a new type of steel grating welding processing equipment that can solve these problems. Summary of the invention

[0005] The purpose of this application is to overcome the above-mentioned technical problems and provide a steel grating welding processing equipment.

The slider can be matched with the rail through a ball bearing or a linear bearing to ensure smooth movement without jamming. In addition, the rail and slider can be equipped with dust covers to prevent dust and debris from entering and extend the service life.

[0031] There are four welding heads, each of which is fixed to the frame by a support rod, and the distance between two adjacent welding heads is equal to achieve uniform distribution on both sides of the steel grating. A temperature sensor is provided inside the welding head to monitor the temperature of the welding head during welding to ensure the safety and stability of the welding process. The welding head can be connected to the frame through an adjustment mechanism, which includes a lead screw and a hand wheel.

Flat-nose pliers are mainly used to clamp rectangular or square steel gratings, V-grooves are suitable for round or special-shaped workpieces, and magnetic chucks are particularly suitable for thin plate workpieces, which can be quickly clamped without additional fixing devices. This diversified clamping method greatly improves the scope of application and flexibility of the equipment.

[0041] The adjustable speed drive system includes a servo motor and a reducer. As a power source, the servo motor has the characteristics of fast response and high precision, and can adjust the speed in real time according to the changes in welding parameters.
