[0002] With the rapid development of my country's machinery manufacturing industry and robotics technology, the processing required by robots is increasing, and the actions are becoming more complex. Using robots not only significantly reduces labor costs but also replaces manual labor in hazardous operations. Over the past 20 years, with the development of digitalization, automation, computer science, and mechanical design technologies, as well as the high importance placed on welding quality, automatic welding has developed into an advanced manufacturing technology. Automatic welding equipment plays an increasingly important role in various industries, and its application scope is rapidly expanding. In modern industrial production, the mechanization and automation of the welding process is an inevitable trend in the modernization of the welding equipment manufacturing industry. Welding robots are industrial robots that perform welding (including cutting and spraying).
[0003] Currently, most welding torches of welding robots use fixed rigid connections. During welding and movement, accidental collisions with the equipment frequently occur. Such collisions may cause deformation or damage to the welding torch, which may affect the welding quality or even damage the equipment and increase maintenance costs. Therefore, a collision avoidance buffer protection device for welding robots is proposed to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a collision avoidance and buffer protection device for welding robots to solve the problems mentioned in the background art.

[0008] Preferably, the moving rod has grooves at both ends for placing rubber blocks. The rubber blocks have a certain resistance effect, which can reduce damage to the moving rod device, and the rubber blocks can be disassembled and replaced.
[0009] Preferably, the movable sleeve is threaded onto the connecting block, and both ends of the spring are fixedly connected to the two sets of movable sleeves, so as to provide a buffering and shock absorption effect on the device.

Each pair of connecting blocks is horizontally arranged front and back, with a movable rod inserted in the middle to connect the baffle plate to the fixed plate. Grooves are cut at both ends of the movable rod, and two sets of rubber blocks are placed in the grooves.

Two sets of movable sleeves are threaded onto the ends of the two sets of connecting blocks that are close to each other, with a connection between the two sets of movable sleeves. The system incorporates springs that, upon impact, generate elasticity to reduce the impact force, thus buffering the welding machinery. Telescopic rods are evenly distributed at the upper end of the baffle, with telescopic sleeves movably inserted into the upper end of the telescopic rods. The height of the anti-collision mechanism can be adjusted as needed. A rubber sleeve covers the outer ring of the telescopic sleeves, protecting them from direct impact damage and reducing maintenance costs.
