Embodiment Construction

[0020] The principle and structure of the present invention will be described in detail below in conjunction with the drawings and embodiments.

[0021] The present invention proposes a rotor entering shaft device, such as figure 1 As shown, the rotor shaft entry device includes: a shaft feeding mechanism 1, a rotor feeding mechanism 2, a shaft installation mechanism 3, and a rotor positioning mechanism 4. The rotor positioning mechanism 4 is installed in the inner hole of the rotor 6 to position the rotor 6.

[0022] like figure 2 As shown, the rotating shaft feeding mechanism 1 includes a rotating shaft storage bin 11. The rotating shaft storage bin 11 is a cuboid hollow structure with an opening at the upper end. The circumferential surfaces of multiple rotating shafts 5 are placed side by side in the rotating shaft storage bin 11. And the rotating shaft storage bin 11 is provided with multiple rows of such rotating shafts 5, each row of rotating shafts 5 is a layer, and ...

Abstract

The invention discloses a rotor shaft-inserting device, which comprises a rotating shaft feeding mechanism, a rotor feeding mechanism, a rotating shaft mounting mechanism and a rotor positioning mechanism, and is characterized in that the rotor positioning mechanism includes a shaft inserting die and a positioning pin, the positioning pin penetrates through the shaft inserting die and the rotor toposition the rotor, a first positioning hole for the positioning pin to penetrate through is arranged below the shaft inserting die, a second positioning hole for a pressing rod of the rotating shaftmounting mechanism to penetrate through is arranged above the shaft inserting die, and the second positioning hole is concentric with the first positioning hole; the rotating shaft feeding mechanismincludes a push rod and a guide structure, the push rod pushes the rotating shaft into the guide structure, and the guide structure guides the rotating shaft to be in a vertical state. The rotor shaft-inserting device has the advantages that the rotor positioning mechanism positions the rotor through an inner hole penetrating through the rotor, the positioning is carried out through the inner holeof the rotor, the positioning accuracy is not influenced by the outer diameter of the rotor, the problem of inaccurate positioning caused by large deviation of the outer diameter of the rotor is avoided, and the rotating shaft can accurately enter the rotor.

Description

technical field [0001] The invention relates to the technical field of assembly, in particular to a rotor shaft-entrying device of a motor. Background technique [0002] The rotor of the motor needs to be assembled into the shaft between the rotor and the shaft. In the prior art, the rotor shaft insertion device uses the outer diameter of the rotor iron core for positioning, and then the rotor and the shaft are assembled. Because the prior art uses rotor iron The outer circle of the core is used for positioning, the outer diameter of the iron core cast aluminum will produce deviations, which will lead to inaccurate positioning of the rotor, so that the concentricity between the rotating shaft and the inner hole of the rotor cannot be guaranteed, so the rotating shaft and the rotor cannot be aligned, which is easy to make The rotor is skewed and shifted, and even the shaft cannot enter the rotor, resulting in bending and breaking of the shaft; at the same time, the existing r...
