Long and short axis adjustment mechanism of motor rotor automatic assembly machine

Abstract

The invention discloses a long and short axis adjustment mechanism of an automatic motor rotor assembly machine. The separating sheet is welded in a storage bin, two moving adjusting sheets parallel to each other are located on both sides of the separating sheet, and the front and rear ends of the moving adjusting sheet pass through respectively. On the two adjustment piece slide rods, the two ends of the adjustment piece slide rods are fixed on the outer sides of the left and right side plates of the storage bin through the "Z" shaped bracket pieces, and the two moving adjustment pieces are respectively equipped with forward rotation screw nuts and The reverse screw nut, the forward screw nut and the reverse screw nut are sleeved on the forward and reverse screw, the forward and reverse screw is equipped with a mechanical digital display positioner, and the forward and reverse screw is installed with a mechanical type The end position of the end of the digital display positioner is fixed with a screw mandrel handwheel. Through the above method, the present invention can be adjusted according to the length of the rotor shaft without replacing the automatic feeding bin, and at the same time, the rotor shaft can be separated into separate rotor shafts for easy grabbing through secondary distribution.

Description

technical field [0001] The invention relates to the field of automatic machinery, in particular to a long and short axis adjustment mechanism of an automatic motor rotor assembly machine. Background technique [0002] There are many types of motors, which are divided into many specifications according to the occasions used and the size of the power. Motors are also widely used in automobiles, including automobile starters and glass lift motors for electric windows. The motor rotor in the motor body is a key component, and the rotor copper wire is wound on it. The rotor has two important parts. , one is the rotor shaft, and the other is the rotor winding frame wound with copper wires. These two parts are assembled through interference fit. The previous assembly process was not good. Over time, it will directly lead to gaps and instability between the two. Moreover, the production efficiency is not high, and the concentricity is poor. There is a new assembly process, which he...

Motors are also widely used in automobiles, including automobile starters and glass lift motors for electric windows. The motor rotor in the motor body is a key component, and the rotor copper wire is wound on it. The rotor has two important parts. , one is the rotor shaft, and the other is the rotor winding frame wound with copper wires. These two parts are assembled through interference fit. The previous assembly process was not good. Over time, it will directly lead to gaps and instability between the two parts. Moreover, the production efficiency is not high, and the concentricity is very poor. There is a new assembly process, which heats the rotor winding frame to 600 degrees, then inserts the rotor shaft into the assembly and cools it rapidly, but this directly leads to the workers being unable to operate at all.
