Description

Technical Field

[0001] This utility model relates to the field of impeller machining tooling, specifically a tooling structure for machining the rear 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 rear end face of an impeller. Its structure is simple and easy to adjust, and it can be used for machining the back plate 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 includes a chuck and an impeller. An impeller retaining ring is fixed on the chuck. The chuck clamps the impeller through the impeller retaining ring. The clamping end of the impeller retaining ring has an L-shaped cross section. The chuck controls the horizontal side of the clamping end of the impeller retaining ring to clamp the outer edge of the impeller. A threaded hole is opened on the vertical side of the clamping end of the impeller retaining ring. An internal hexagon screw passes through the threaded hole and abuts against the front end face of the impeller.

[0005] In a further improvement, the impeller retaining ring is fixed to the jaws by welding.

[0006] In a further improvement, a nut is fitted onto the hexagon socket screw, which is screwed onto the impeller retaining ring to adjust the verticality of the impeller back plate. After adjustment, the screw is tightened by the nut.

[0007] The advantages of this utility model are: simple structure and easy adjustment, which can be used for back plate processing of multiple impeller models. It not only saves the manufacturing cost of multiple tooling sets, but also saves the time required for tooling replacement and adjustment, thus greatly improving production efficiency.
