Description

The Qu Pian mechanisms of blade inserting impeller assembly machine

Technical field

The utility model is related to a kind of Automated assembly field, more particularly to a kind of blade inserting impeller assembly machine takes piece machine Structure.

Background technology

It is commonly used in the blade inserting impeller of wind turbine or kitchen ventilator, basic structure has generally included spaced successively Along multiple blades of annular array distribution, and it is respectively arranged at the upper press cover of annular spread vane tip and is set to annular point The blade upper and lower ends of the lower cover of cloth blade bottom, impeller form inserted sheet, and inserted sheet passes through the slot and lower cover of upper press cover Slot, and inserted sheet is through being pressed against on the end face of upper press cover and lower cover after bending.

Currently, most of blade installation process of above-mentioned this blade inserting impeller is realized by manually inserted sheet, that is, rush One end is first inserted into the lower cover of round slotted hole by the blade made by hand, waits for that the slot that lower cover one encloses sticks with leaf After piece, then upper press cover is set above blade again, the other end inserted sheet of blade is inserted into the corresponding slot of upper press cover, blade Inserted sheet stretch out in except the slot of upper and lower gland finally by the bending of punch riveting or directly beat press-bending by hand so that Upper and lower gland is linked together with blade fixation.

It is entitled in Publication No. CN204413581U《The material-feeding and fetching integrated device of blade inserting impeller》Chinese patent and Improvement patent publication No. on its basis is that CN205367144U is entitled《A kind of rotor machine of impeller assembly driving mechanism Structure》Chinese patent, disclose the feeding in blade inserting impeller assembly machine and the integrated apparatus structure of feeding, substantially process For：Blade is first piled in magazine, and so that blade is in vertical order arrangement side in magazine by the position limiting structure of magazine Formula is provided with discharge port and shaft in the bottom of magazine, and shaft therein includes magnetic cylindrical section and is arranged in magnetic cylinder Groove at section, the width and depth of groove match with blade, when needing to take out blade from magazine, shaft rotation, Blade positioned at magazine bottom is in groove, will be produced therewith.Simultaneously, the pick-up claw recycling of material fetching mechanism, to Linkage is hinged on the feeding claw on feeding table so that feeding claw is overturn by the effect of torsional spring to the direction of feeding table, simultaneously will Blade in shaft is pressed between feeding claw and feeding table, and then pick-up claw continues to protract, and will be located at feeding claw and feeding Blade between platform is taken away, and into next station, while feeding claw turns over the linkage for continuing by pick-up claw, waits for next time Action.

Later, the improvement to the driving mechanism of feeding claw, such as publication number have been carried out again on the basis of above-mentioned patent CN106516731A, it is entitled《The material fetching mechanism of blade inserting impeller assembly machine》Disclosed in structure so that feeding claw exists During blade is transported to feeding table from shaft, movement becomes more soft smooth and controllability greatly increases.

However, in the processing and transport stacking process of blade, blade is susceptible to crimping and burr phenomena, above-mentioned Rotation takes piece, due to being that single blade is sucked, piece is then taken by way of rotation from the blade of stacking, be very easy to by In the influence of burr, there is the phenomenon that taking piece to have some setbacks, influences actual automatic inserted sheet integrated artistic.
