Impeller assembly machine

Abstract

The invention discloses an impeller assembly machine which comprises a machine base, a mold arranged on the machine base and allowing blades of an impeller to be inserted therein, a push mechanism arranged on the machine base and used for pushing the blades to the mold and a rolling and riveting mechanism for riveting the impeller. The height of the mold is equal to half of the length of the blades. The rolling and riveting mechanism comprises an upper riveting mechanism for bending and fixing an upper gland of the impeller and insertion pieces of the blades and a middle riveting mechanism for riveting the blade in the middle of the impeller and a reinforcing partition plate arranged in the middle of the impeller. The middle riveting mechanism capable of riveting the reinforcing partition plate of the double-layer impeller is additionally arranged on the basis that only the upper gland and a lower gland of the impeller can be riveted to the impeller, so that only one working procedure is added without affecting the original riveting efficiency, and the machining efficiency of the double-layer impeller is improved greatly.

Description

technical field [0001] The invention relates to an impeller assembly device of a range hood, more specifically, to an impeller assembly machine. Background technique [0002] The common vane-type impeller used for fans or range hoods usually includes a plurality of blades arranged at intervals along the annular array in sequence, and upper glands respectively arranged on the top of the annular distribution blades and arranged on the annular distribution blades. The lower gland at the bottom of the blade, the upper and lower ends of the blade of the impeller are formed with inserts, the inserts pass through the slot holes of the upper gland and the slots of the lower gland, and the inserts are bent and pressed against the upper gland and on the end face of the lower gland. [0003] At present, the blade installation process of the above-mentioned blade impeller is mostly realized by manual blade insertion, that is, one end of the punched blade is manually inserted into the l...

Problems solved by technology

[0005] However, the rotor structure in the above-mentioned patent has the problem of unreasonable design and inability to quickly rotate the rotor, and the adjustability of the rolling riveting mechanism is also very poor. The most important thing is that it is only suitable for assembling impellers with a single-layer structure. Due to the long overall length of the impeller, and the middle part of the impeller also needs to install a reinforced isolation plate that divides the impeller into two chambers, which cannot be realized only by using the above-mentioned patented equipment.
