Description

Automatic plug-in mounting machine for liftable stator and rotor of small generator
Technical Field
The invention relates to the field of generator installation equipment, in particular to an automatic plug-in machine for a liftable stator and a liftable rotor of a small generator.
Background
The stator and rotor assembly or general assembly of the generator comprises sleeving the rotor into the stator, adjusting an air gap, and installing other components such as an external fan, a brush device and the like. After final assembly, the test should be performed one by one. These projects or process flows have a great impact on the quality and performance of the generator due to the size, type and application of the generator, or the deletion or addition and refinement. Before assembly, the quantity and quality of the parts are checked, the greasy dirt and dust of each part are cleaned, and the protruding insulation is removed. Burrs and paint covers of the matched parts are carefully removed, otherwise the matching accuracy and the air gap uniformity are affected, and electrical or mechanical faults are caused. During assembly, sleeving the rotor into the stator is one of the key procedures. Careless operation or unsuitable operation method easily causes the winding to be bumped, scratched or damaged. In special cases, even a deformation of the shaft results. During sleeving, the relative positions of the shaft extension and the outlet box should be noted, and the requirements of drawings should be met.
The installation process of the generator plays a crucial role in the motion performance of the whole system.

The mounting structure of the stator mounting portion and the bed portion is shown in fig. 1. The lower base plate 10 is placed on the bed 1. Side frames 11 are arranged on two sides of the lower bottom plate 10, and the end faces of the side frames 11 are of U-shaped structures. A plurality of rollers 12 are arranged in the side frames 11, and after the side frames 11 wrap the guide rails, the rollers 12 are meshed with the guide rails 4, so that the moving track of the stator mounting part is limited. The lower bottom plate 10 is provided with a hydraulic cylinder 13 and a plurality of guide rods 27, the hydraulic cylinder 13 is communicated with the hydraulic station 7 through a pipeline, and the hydraulic station 7 is a power source of the hydraulic cylinder 13.

The upper base plate 14 is mounted on the upper end of the hydraulic cylinder 13, and the motor stator 15 is placed on the upper base plate 14.
The X-direction movement of the stator mounting is achieved by the output gear of the reducer 17 cooperating with the rack 18. As shown in fig. 3, a rack 18 is fixedly provided on the side wall of the seat channel 3, and a motor 16 and a decelerator 17 are mounted on the stator mounting portion. The movement of the stator mounting portion is achieved by the output gear on the speed reducer 17 meshing with the rack 18. The rotation speed of the motor 16 is controlled by the control cabinet 5.
As shown in fig. 2, a main shaft 8 is mounted on the side of the control cabinet 5, a main shaft V-shaped wedge 9 is mounted on the end surface of the main shaft 8, and a motor rotor 26 is placed and fixed by matching a tailstock V-shaped wedge 24 provided on the rotor mounting part with the main shaft V-shaped wedge 9.
The rotor mounting structure is composed of a tailstock 19 and a tailshaft 23 as shown in fig. 5. The whole tailstock 19 is mounted on the bed 1.

During installation, the guide rail 4 is arranged between the tailstock 19 and the tailstock fixing block 20, and when the whole stator installation part is required to be fixed, the tailstock fastening handle 21 is rotated, so that the distance between the tailstock fixing block 20 and the tailstock 19 is shortened, the guide rail 4 is clamped, and the fixation of the rotor installation part is realized.
The rotor is mounted by the cooperation of the tailstock V-shaped wedge 24 and the main shaft V-shaped wedge 9. As shown in fig. 5, a tailstock 23 is attached to the tailstock 19, a tailstock V-shaped wedge 24 is attached to an end surface of the tailstock 23, and a motor rotor 26 is placed on the tailstock V-shaped wedge 24 and the spindle V-shaped wedge 9. When the motor is required to be fixed, the V-shaped included angle is adjusted by adjusting the wedge block fixing rotating handles 25 on the main shaft V-shaped wedge block 9 and the tailstock V-shaped wedge block 24, so that the main shaft V-shaped wedge block 9 and the tailstock V-shaped wedge block 24 fix the motor rotor 26.

The motor stator is placed on the stator mounting part through overhead travelling crane hoist and mount, and the hydraulic system is controlled to start working through the switch board 5, and the pneumatic cylinder 13 goes up and down to drive stator mounting part to the vertical direction and goes up and down, and after the stator mounting part rises to its preset position, pneumatic cylinder 13 stops the motion, and the movable working table stops and keeps on the preset position.
After the stator installation part rises and adjusts to the target position, through the control cabinet 5 control, output gear and rack 18 cooperation on by the reduction gear 17 for the stator installation part moves to the position that the horizontal direction is close to main shaft 8, until touching the limit switch that is located machine head side, and stator installation part stops the motion, and stator installation part adjusts to the target position.
The crown block hoisting places one end of the motor rotor 26 on the main shaft end V-shaped wedge 9 and the other end on the tailstock V-shaped wedge 24. Because the motor types are different, the rotor length of the motor is also different, and the tailstock 19 can adjust the fixed position in a certain range according to the length of the motor rotor. The tailstock 19 is initially adjusted to coarse adjustment, and the tailstock hand wheel 22 can change rotational motion to horizontal movement of the tailstock V-shaped wedge 24 to achieve fine adjustment of the wedge.
During installation, the stator installation part is controlled to move towards the direction of the rotor installation part by the control cabinet 5, and the motor stator is sleeved on the rotor to complete the assembly of the stator and the rotor once.
