Abstract
Description
Technical Field
[0001] This utility model relates to the field of impeller machining tooling, specifically a tooling structure for machining the front end face of an impeller. Background Technology
[0002] Currently, open and semi-open impellers are mainly used in sanitary pumps in the food, beverage, dairy, biopharmaceutical, fructose, and daily chemical industries. These impellers are the core components of sanitary pumps. Currently, most impellers are clamped in machine tool chucks or machined using multiple simple tooling sets to process different impeller models. However, the uncertainty in the precision of the casting blanks makes calibration very troublesome and wastes too much machining time. Therefore, a good tooling is urgently needed to ensure production costs, machining accuracy, and processing efficiency. Utility Model Content
[0003] To address the problems of existing technologies, this utility model provides a tooling structure for machining the front end face of an impeller. Its structure is simple and easy to adjust, and it can be used for machining the front end face of multiple impeller models. This not only saves the manufacturing cost of multiple tooling sets, but also saves the time required for tooling changes and adjustments, thus greatly improving production efficiency.
[0004] This utility model discloses a tooling structure for machining the front end face of an impeller, including a shaft, a welding flange, and a back flange. The welding flange and the back flange are fixedly connected, and a through hole is opened in the center of the welding flange and the back flange. One end of the shaft is connected to a power device, and the other end passes through the through hole in the center of the welding flange and the back flange and is connected to the central connection hole of the rear end face of the impeller. The rear end face of the impeller is close to the back flange.
[0005] In a further improvement, the shaft-driven automatic power device, from the connecting end to the impeller connecting end, includes a power section, a flange section, and an impeller section in sequence, with the outer diameter of the three sections decreasing sequentially.
[0006] In a further improvement, the welded flange is fitted onto the outer edge of the shaft flange section, and a gap is left between the back plate flange and the impeller section of the shaft.
[0007] In a further improvement, the welded flange and the back plate flange are fixedly connected by screws and nuts.
[0008] The advantages of this utility model are: simple structure and easy adjustment, which can be used for processing the front end face of multiple impeller models. It not only saves the manufacturing cost of multiple tooling sets, but also saves the time required for tooling change and adjustment, thus greatly improving production efficiency.
