Description

Technical Field

[0001] The utility model relates to the technical field of welding tooling, in particular to a guardrail welding tooling for a robot. Background Art

[0002] With the development of technology, the intelligence and networking level of welding robots are constantly improving, which means that they can complete complex welding tasks more accurately, reduce manual intervention, and thus significantly improve production efficiency. Robot welding technology is also applied in the field of guardrail welding. Since guardrails are mostly welded together by splicing multiple steel pipes, tooling is required to fix the various parts of the guardrail during the welding process.

[0003] After searching, the Chinese patent document, announcement number: CN209578629U, discloses a guardrail welding tool for robots. By setting a positioning block on the outer frame or the inner frame, the workpiece is fixed in the groove of the positioning block, and a pressure plate is used to firmly fix the workpiece in the groove. The use of the pressure plate and the positioning block reduces the number of elbow clamps and provides welding space for the robot welding gun. In addition, by setting a magnet block on the tooling, the magnet block is set on the support beam or the inner / outer frame where the reinforcement plate is located, the reinforcement plate can be fixed, which saves fixtures and is flexible and convenient, greatly improving the welding efficiency.

[0004] However, the above welding tooling still has significant defects in actual use. First, the pressure plate needs to rely on the vertical elbow clamp to press the guardrail components, and the position of the vertical elbow clamp may affect the stroke of the welding robot, and the device can only be used for guardrails of a certain size, and has low applicability.
