Welding positioner special for upper and lower square butt joint welding seams of excavator movable arms and using method of welding positioner

Abstract

The invention discloses a welding positioner special for upper and lower square butt joint welding seams of excavator movable arms and a using method of the welding positioner. The welding positioner and the using method solve the bottleneck problem in the operation of welding the movable arms. Due to welding of the square butt joint welding seams of the movable arms, the welding can be well combined with a welding device, mechanization of the welding is achieved, and production efficiency and welding quality are improved. The problems that at present, production efficiency is low and product quality cannot be ensured are solved. Meanwhile, the labor intensity of workers is reduced, and the production cost is greatly reduced. Above all, safe and civilized production is achieved, and field management is also facilitated. The welding positioner special for the upper and lower square butt joint welding seams of the excavator movable arms can complete the welding of movable arms of different types and end the situation that no device is used for welding the movable arms.

Description

technical field [0001] The invention relates to a welding positioner, in particular to a special welding positioner for the upper and lower flat butt welds of excavator arms. The displacement needs of the lower flat butt welding seam are convenient for welding operation, and it is suitable for various types of booms. The invention also relates to a method for using the special welding positioner for the upper and lower flat butt welds of the excavator arm. Background technique [0002] In the boom welding process, there is no suitable welding positioner that can meet the welding of special-shaped structural parts like the boom. Many companies have designed many forms of positioners, or they cannot get the best welding position, or Unable to achieve a reasonable welding position, we can only adopt the most primitive welding method, which is to use a crane to weld. Not to mention that this method cannot obtain the best welding position, and it is also impossible to fine-tune ...

Problems solved by technology

[0002] In the boom welding process, there is no suitable welding positioner that can meet the welding of special-shaped structural parts like the boom. Many companies have designed many forms of positioners, or they cannot get the best welding position, or Unable to achieve a reasonable welding position, we can only adopt the most primitive welding method, which is to use a crane to weld. Not to mention that this method cannot obtain the best welding position, and it is also impossible to fine-tune the welding position, which is even more dangerous. extremely unsafe

Foreign-funded enterprises also encountered the same problem when welding the boom, and they did not have professional equipment. The method was only a step ahead of welding with a crane. They made two brackets at both ends of the boom to support the two ends of the boom respectively. For welding, the position is not satisfactory, and the operation is quite dangerous. Even so, it is still necessary to use a crane to turn it up and down, which is quite difficult; more importantly: there is no special equipment for the upper and lower flat butt welds of the boom. Crouching on the ground for welding, it shows that the welding of the boom has not broken away from the era of manual work, and is maintained at a relatively low level of work
