Problems solved by technology

[0003] When the stator and rotor of the current engine are finished on the machine tool, the next set of stator and rotor can be finished only after one set of stator and rotor is finished, which greatly affects the device’s ability to adjust the engine’s stator and rotor. Processing efficiency; and in the process of finishing the stator and rotor of the current automobile engine, the metal debris generated will often cover the processing machine tool. These debris will not only fall into some corners of the machine tool that are difficult to clean, but also affect the The normal operation of the transmission structure on the machine tool; at the same time, during the finishing process of the stator and rotor of the current automobile engine, a large amount of metal dust is often generated, which will also greatly increase the wear of the rotating parts of the machine tool, and in the finishing process of the stator and rotor Finally, due to grinding and turning, the stator and rotor will generate a lot of heat, which is not convenient for quick replacement of the stator and rotor after processing

Embodiment 1

[0053] Example 1, as Figure 2-4 As shown, before finishing the stator and rotor, the operator passes the hand through the square through hole and turns a set of handwheels 803 close to the door of the processing chamber 1 counterclockwise, and uses the screw thread to force the threaded rod 805 to approach the first servo motor One end of 6 moves, and drives the rotating plate 801 to approach the first servo motor 6 together, the distance between the rotating plate 801 and the rotating deck 9 increases, and then the operator manually inserts one end of the stator and rotor into the concave of the rotating deck 9 slot, and turn the hand wheel 803 clockwise to allow the other end of the stator and rotor to snap into the slot 806, thereby installing the stator and rotor for subsequent finishing of the stator and rotor, and replacing the finished stator and rotor , then turn the hand wheel 803 clockwise to drive the threaded rod 805 to rotate clockwise, allowing the rotating plat...

Embodiment 2

[0054] Example 2, such as Figure 1-10 As shown, when the device is finishing the stator and rotor, the second servo motor 24 is first controlled to rotate clockwise through the control panel 3, and the transmission of the driving gear 11 and the second ring rack 19 is used to drive the two groups of turntables 13 to reverse each time. The hour hand rotates 90°, so that the stator and rotor pass through the bottom of the grinding device 2 first, then pass through one side of the turning assembly 7 and the top of the rotating ring 125, and when the turntable 13 stops, the first servo motor 6 drives the rotating chamber 14 rotates, and the rotating chamber 14 drives the three groups of rotating decks 9 to rotate synchronously through the driving gear 18 on the first rotating tube 17 and the three groups of transmission gears 23, thereby driving the three groups of stators and rotors to rotate synchronously, and the grinding device 2 is used to pair the stators and rotors Grindin...

Embodiment 3

[0055] Example 3, such as Figure 2-6 As shown in and 9-10, when dust is removed inside the processing chamber 1, the air pump 105 is controlled by the control panel 3 to suck air, and the metal dust generated by the grinding device 2 is mixed with air and enters the rotating chamber 14 through the air inlet 15 Afterwards, the metal dust and air enter the interior of the filter chamber 102 through the first rotating tube 17, and the metal dust will be filtered and blocked by three sets of filter screens 101. After the filtered air passes through the heat exchange tube 104, it is pumped The air pump 105 is transported to the inside of the air pipe 106, and the filtered air is finally sprayed out through the nozzle 107, and the surface of a group of stators and rotors at the bottom is blown to cool down, so that the processed stators and rotors can be quickly replaced, and the nozzle 107 sprays out The air in the air will also blow and remove dust on the surface of the set of st...

Abstract

The invention discloses a finish machining process of a stator and a rotor for an automobile engine, which comprises the following steps of: 1, blanking and cutting a raw material silicon steel sheet into strips, punching stator sheets and rotor sheets with punching grooves by utilizing a punching machine, coating insulating paint on the stator sheets and the rotor sheets in a rolling manner, and laminating the stator sheets and the rotor sheets into the stator and the rotor; and 2, pressing the stator into the casing to form a stator finished product, penetrating the rotor through a shaft, and processing a rotor shaft to form a rotor finished product. A second servo motor is controlled to rotate clockwise, transmission of a driving gear and a second annular rack is utilized to drive two sets of rotating discs to rotate by 90 degrees anticlockwise every time, a rotating bin drives three sets of stators and rotors to rotate synchronously through cooperation of a driving gear on a first rotating pipe and three sets of transmission gears, and the stators and the rotors are ground through a grinding device. The turning assembly is matched with the rotating stator and rotor to turn the stator and rotor, and in the process, an operator can manually replace a set of stator and rotor close to the machining bin door.

Description

technical field [0001] The invention relates to the technical field of automobile engine processing, in particular to a finishing process for a stator and rotor used in an automobile engine. Background technique [0002] The fixed part of the motor is called the stator, on which a pair of stationary main magnetic poles of DC excitation are installed; while the rotating part (rotor-rotor) is called the armature core, and the armature winding is installed on it. The induced electromotive force acts as a rotating magnetic field, and then generates electromagnetic torque for energy conversion. It is distinguished by the shape of the stator winding and the embedded installation method. The stator winding can be divided into centralized and distributed according to the shape of the coil winding and the embedded installation wiring method. Two categories. [0003] When the stator and rotor of the current engine are finished on the machine tool, the next set of stator and rotor can...
