Description

Technical Field

[0001] The present application relates to the technical field of welding machines, and in particular, to a welding machine auxiliary measurement device, method, measurement device and welding machine. Background Art

[0002] The welding machine is an important equipment in the cold rolling production line, which is mainly used to weld the tail and head of the strip to achieve continuous production. When welding the tail and head of the strip, the accuracy of the overlap or butt joint is high. Therefore, the welding machine needs to be measured and adjusted periodically to ensure the accuracy of the welding machine.

[0003] When the welder is in the adjustment position, the measured part is far away from the precision reference position of the welder, making it difficult to measure directly. Therefore, the welder is moved to the working position so that the measured part and the precision reference position of the welder are close to each other, and then direct measurement can be performed. In order to ensure that the welder meets the accuracy requirements, multiple measurements and adjustments are required. Therefore, during actual measurement and adjustment, the welder needs to move back and forth between the working position and the adjustment position, which makes the measurement and adjustment efficiency low.

[0004] In addition, when measuring the accuracy of the measured parts related to the clamps and shear blades, the operator needs to drill into an extremely narrow space with his feet suspended in the air. Some measurements also require moving the welding carriage, which is prone to safety accidents and has low measurement efficiency. Summary of the invention

When the welding machine is in the adjustment position, the measured part is far from the precision reference surface of the welding machine, and it is not convenient to measure the measured part.

In this process, the welding machine needs to be moved back and forth between the working position and the adjustment position many times, which makes the efficiency of welding machine measurement and adjustment low.
