Abstract

The invention discloses a clamping device for processing a semi-open impeller, which comprises a base, an active pressing mechanism arranged at the center of the upper surface of the base, and a group of passive pressing mechanisms with the same structure distributed around the upper surface of the base. tightening mechanism; the impeller to be processed is sleeved on the positioning screw in the active compression mechanism through the shaft hole, and the lower end of the impeller to be processed presses down on the inner side of the hinge point of the compression connecting rod in the passive compression mechanism, and the compression The compression part of the tight connecting rod located outside the hinge point passively presses down around the impeller to be processed, and the compression nut on the positioning screw in the active compression mechanism is screwed down to make the pressure plate press down on the middle part of the impeller to be processed to realize the impeller to be processed. positioning. The clamping device of the present invention can stably clamp the impeller, and the clamping force is evenly distributed.

Description

technical field [0001] The invention relates to a clamping device for processing a semi-open impeller, which belongs to the field of impeller processing. Background technique [0002] As the core component of the pump, the impeller is widely used in many fields. The whole is generally made of high-strength, difficult-to-process materials, no cracks and defects are allowed, the blades are thin, the twist is large, the blades are long, and they are easy to deform under force. The removal rate is very high, so its processing technology has always been a difficult problem. At the same time, designing a set of reliable and simple tooling to ensure smooth processing is also an important issue that cannot be ignored. [0003] The traditional open impeller is clamped by clamping the blade with 3 claws or 4 claws. The clamping position is small, and the blade is easily broken if the clamping force is too large; at the same time, the processing efficiency is low and there are potenti...
