Description

[0001] The invention belongs to the technical field of impeller welding processing, and in particular relates to an impeller processing device. Background Art

[0002] Impellers are key components in many mechanical equipment and are widely used in fans, pumps, compressors and other fields. In the manufacturing process of impellers, welding the blades to the base plate is an important step. Traditional impeller welding processing technology is usually carried out manually or semi-automatically, including the steps of handling the base plate, conveying, positioning and welding the blades, which has the following disadvantages: 1. Low degree of automation: Most of the existing impeller welding processing equipment relies on manual operation, such as manual handling of the base plate, manual positioning of the blades, and manual welding. Not only is the operation efficiency low, but the operators also need to frequently carry heavy base plates and blades and perform delicate positioning and welding work. This high-intensity physical labor can easily lead to operator fatigue and increase the risk of work-related accidents; 2. Unstable product quality: Differences in technical levels between operators can lead to poor product consistency. Manual operation can easily introduce various errors, such as inaccurate positioning and inconsistent welding quality, which results in a low pass rate for the final product. These problems not only increase rework and scrap rates, but may also affect the performance and life of the final product.

During the transport of the blade 150, after a group of clamping assemblies 520 grab the blade 150, the first motor 511 drives the assembly plate 512 to rotate until the second group of clamping assemblies 520 grab the blade 150, and this is repeated until all the clamping assemblies 520 have been grabbed. Then the second motor 540 drives the planetary transmission structure so that all the blades 150 rotate to a specific processing angle. The welding assembly 530 welds the blade 150 and the base plate 140. After welding is completed, the processing device 500 transports the impeller to the blanking channel 120 to complete the blanking.
