Manufacturing surface finishing clamp for water pump impeller

Abstract

The invention discloses a manufacturing surface finishing clamp for a water pump impeller, and relates to the technical field of clamp clamping. The manufacturing surface finishing clamp comprises a workbench, the top end of the workbench is arranged as a horizontal table top, a plurality of disc-shaped positioning tables are arranged on the table top of the workbench, a disc-shaped positioning boss is arranged at the circle center position of the top end of each positioning table, a guide rod upright on the corresponding table top is arranged at the top end of each positioning boss, a plurality of sliding grooves are formed in the outer wall, adjacent to the top end of the corresponding positioning boss, of each guide rod, and an ejector rod receding hole is formed in the inner wall of each guide rod. According to the manufacturing surface finishing clamp for the water pump impeller, the guide rods are arranged at the top ends of the positioning tables, the center hole of the water pump impeller sleeves the guide rods, a plurality of outer clamping jaws are arranged on the outer ring of each positioning table at equal intervals, and the water pump impeller can be subjected to outside clamping through clamping of the outer clamping jaws. The inner ring of the water pump impeller is convenient to finish and grind.

Description

technical field [0001] The invention relates to the technical field of fixture clamping, in particular to a surface finishing fixture for manufacturing water pump impellers. Background technique [0002] The water pump impeller is a disc-shaped blade made of cast iron. The blades on the water pump impeller play a major role. The shape and size of the water pump impeller are closely related to the performance of the water pump. Generally, the water pump impeller can be divided into single-suction type and double-suction type. There are two types, the single-suction impeller absorbs water from one side, the small-flow pump impeller mostly adopts this type, the double-suction impeller absorbs water from both sides, and the large-flow pump impeller adopts double-suction impeller. [0003] After the water pump impeller is cast, the surface of the impeller needs to be finished and polished. When the impeller is polished and finished, the water pump impeller needs to be clamped and...
