Air conditioner outdoor unit assembling production line and axial flow fan blade grabbing device thereof

Abstract

The invention provides an air conditioner outdoor unit assembling production line and an axial-flow fan blade grabbing device.The axial-flow fan blade grabbing device comprises an operation control mechanism, a supporting frame, a positioning pin, an elastic piece, a driving control mechanism, a mounting plate, a grabbing control mechanism and at least two clamping jaws, and the operation control mechanism can control the supporting frame to move and rotate in multiple degrees of freedom; the driving control mechanism is arranged on the supporting frame and can control the mounting plate to move relative to the supporting frame, a grabbing area is defined by the multiple clamping jaws, the positioning pin can be movably supported on the supporting frame in the moving direction of the mounting plate, the positioning end of the positioning pin can be located in the grabbing area, and the elastic piece forces the positioning end to move towards the grabbing area. And the cross section of the positioning end in the moving direction perpendicular to the mounting plate is D-shaped. According to the axial-flow fan blade grabbing device, axial-flow fan blades can be accurately clamped to be aligned and assembled, the assembling precision is high, the automation degree is high, the assembling efficiency is high, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of automated production equipment, in particular to an assembly production line for an air conditioner external unit and an axial flow fan blade grabbing device thereof. Background technique [0002] The air conditioner external unit includes a motor and an axial flow fan blade, wherein the axial flow fan blade is sleeved on a motor shaft of the motor. see figure 1 , the axial flow fan 1 includes a hub 11, the outer side wall of the hub 11 is arranged with a plurality of blades 12 in the circumferential direction, the hub 11 is provided with a hub 13 at the center, and the center of the hub 13 is provided with a shaft for passing through the motor shaft hole. In order to be able to be positioned circumferentially with the motor shaft, there is a D-shaped hole 14 in the shaft hole, that is, the cross-section of the D-shaped hole 14 in the radial direction of the shaft hole is arranged in a D-shaped surface,...

AI Technical Summary

Problems solved by technology

[0003] When the air conditioner external unit assembly line is assembling the air conditioner external unit, since the motor shaft of the motor is in a rotatable state, it is difficult for the automated production line to align the D-shaped hole 14 of the axial fan blade 1 with the D-shaped shaft of the motor shaft for assembly. Then the only way is to manually align the D-shaped hole 14 of the axial fan blade 1 with the D-shaped shaft of the motor shaft for assembly, but the production efficiency of manual alignment and assembly is low, resulting in high production costs and high labor intensity.
