Description

Technical Field

[0001] The utility model relates to the technical field of welding positioners, in particular to a full hydraulic lifting welding positioner. Background Art

[0002] The welding positioner is a device used to drag the workpiece to be welded so that the weld to be welded moves to the ideal position for welding. It changes the welding operations that may require vertical welding, overhead welding, etc., which are difficult to ensure the welding quality. Therefore, it ensures the welding quality and improves the welding productivity and the safety of the production process. If a positioner drags the weldment and only makes linear motion, even in three dimensions, it is impossible to change the posture of the weld to meet the welding requirements. In other words, the displacement motion is a rotary motion, which is called the master degree of freedom of the positioner. Considering the differences between hand welding and automatic welding, Purpose: When selecting and designing a welding positioner, in addition to the main positioner degree of freedom, it is also necessary to consider adding auxiliary positioner degrees of freedom. For some weldments, due to the simple distribution of welds, one rotational degree of freedom can solve the ship welding requirements of most and important welds in the weldments. For the remaining small number of non-important welds, although ship fillet welding cannot be implemented, flat fillet welding can be implemented. In this way, in order to simplify the equipment cost, the process considers using a single degree of freedom or a functionally degraded welding positioner, that is, a single rotary positioner; if encountering large-scale welding, the lifting and lowering movement degrees of freedom can be increased, or a mobile tailstock can be selected.

[0003] At present, many welding positioners lack stability during the flipping process due to structural limitations or drive structure selection, which affects the accuracy and strength of the subsequent welding process.

[0004] For example, the fully hydraulic lifting welding positioner disclosed in Chinese patent CN207953057U adopts a slewing support structure for the rotation of the L-plate and the rotating table, which has a large load-bearing capacity, a long service life, and reliable performance. In addition, the second motor passes through the first current guide brush mechanism to achieve infinite rotation. The welding current has a special second current guide brush mechanism and does not flow through gears and other mechanisms. The performance is stable. It is driven by the first motor and the second motor, can be self-locked in any position, and is safe and reliable.

[0005] However, the fully hydraulic lifting welding positioner is unable to process the smoke generated during the welding process, causing the smoke to be dispersed in the air and inhaled by the workers, causing damage to the workers' health.

[0006] For this reason we urgently need to provide a kind of full hydraulic lifting welding positioner. Utility Model Content

[0007] The utility model aims to provide a fully hydraulic lifting welding positioner to solve the problem in the background technology that the smoke generated during welding cannot be processed, resulting in the smoke being dispersed in the air and inhaled by workers, causing harm to the workers' health.

[0013] Preferably, one end of the threaded rod close to the clamping plate is fixedly mounted on the inner ring of the bearing, and the bearing is used to prevent the clamping plate from rotating along with the threaded rod when the threaded rod rotates.
