Description

Technical Field

[0001] The utility model relates to the technical field of stator-rotor assembly, in particular to a stator-rotor assembly device. Background Art

[0002] The motor stator and rotor are important components of motors such as generators and starters.

[0003] Application No. CN202321791226.9 discloses a stator-rotor assembly mechanism. In view of the problem that the existing stator-rotor assembly machine generally needs to fix the stator and the rotor separately when assembling the motor stator and the rotor, the operation is cumbersome, and the installation is inconvenient, the following scheme is proposed, which includes a base, the top of the base is rotatably connected with four symmetrically arranged support rods, the tops of the four support rods are rotatably connected with the same top ring, the top of the top ring is fixedly installed with a first motor, the output shaft of the first motor is fixedly connected with the corresponding support rods, the four support rods are threaded with the same positioning ring, the top of the base is provided with a push mechanism, and the positioning ring is provided with a clamping mechanism. The utility model is simple to operate, easy to use, and can simultaneously position the motor stator and the motor rotor, so as to facilitate automatic fitting installation. However, in specific use, the vertical coaxial positioning speed of the stator and the rotor is slow, which reduces the assembly efficiency. Utility Model Content

[0004] The utility model aims to solve one of the technical problems existing in the prior art or related technology.

[0005] To this end, the technical solution adopted in this utility model is:

[0006] A stator-rotor assembly device comprises a clamping module and a calibration module, wherein the clamping module comprises a frame, a T-shaped slide plate sliding through the top of the frame, a rectangular plate connected to the T-shaped slide plate, two pressure plates movably connected to the rectangular plate, a conveyor belt movably embedded in the inner side of the pressure plate, a bidirectional electric push rod connected between the two pressure plates, a cross plate installed inside the frame, a touch switch and two thin springs embedded in the top of the bidirectional electric push rod, and a plate body connected between the two thin springs, wherein the touch switch is electrically connected to the bidirectional electric push rod, and the calibration module comprises a threaded rod embedded in the top of the frame and connected to the T-shaped slide plate, a motor connected between the frame and the threaded rod, a hydraulic cylinder installed on the front side of the T-shaped slide plate, a connecting plate connected to the bottom of the rectangular plate, a cross bar plugged into the connecting plate, a V-shaped plate connected to one end of the cross bar, a spring connected between the connecting plate and the V-shaped plate, and a limit platform installed inside the frame.

[0007] By adopting the above technical solution, after the rotor is tightly pressed by the two pressure plates, the external PLC starts the motor, and then the threaded rod moves the T-shaped slide, and then the clamped rotor and connecting plate follow the movement. During this process, the staff puts the stator on the lower bend of the limit table. When the rectangular plate collides with the bend on the limit table, the V-shaped plate presses the stator so that the stator is close to the outer wall of the lower bend of the limit table, thereby realizing the vertical coaxiality of the stator and the rotor, and then the external PLC starts the hydraulic cylinder, and the hydraulic cylinder presses the rotor into the stator, thereby completing the assembly operation and improving the assembly efficiency.

[0008] In a preferred example, the utility model can be further configured as follows: the two pressing plates are vertically symmetrical about the hydraulic cylinder, and the pressing plates are arranged in an isosceles trapezoid.

[0009] In a preferred example, the utility model can be further configured as follows: the top of the plate body is flush with the top of the horizontal plate, and the bottom of the rectangular plate is in contact with the top of the horizontal plate.

[0010] In a preferred example, the utility model can be further configured as follows: the motor and the hydraulic cylinder are both electrically connected to an external PLC.

[0011] In a preferred example, the utility model can be further configured as follows: the V-shaped plate is located between the connecting plate and the limiting platform, and the spring is arranged between the connecting plate and the V-shaped plate.

[0012] In a preferred example, the utility model can be further configured as follows: the spring is movably sleeved on the outside of the cross bar.

[0013] In a preferred example, the utility model can be further configured as follows: an upper bend and a lower bend are provided on one side of the limit platform, the V-shaped plate is transversely aligned with the lower bend, and the bottom of the rectangular plate is transversely aligned with the upper bend.

[0014] By adopting the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0015] 1. In the utility model, after the rotor is tightly pressed by two pressure plates, the external PLC starts the motor, and then the threaded rod moves the T-shaped slide, and then the clamped rotor and connecting plate follow the movement. During this process, the staff puts the stator on the lower bend of the limit platform. When the rectangular plate collides with the bend on the limit platform, the V-shaped plate presses the stator so that the stator is close to the outer wall of the lower bend of the limit platform, thereby realizing the vertical coaxiality of the stator and the rotor, and then the external PLC starts the hydraulic cylinder, and the hydraulic cylinder presses the rotor into the stator, thereby completing the assembly operation and improving the assembly efficiency.

[0016] 2. In the utility model, the rotor is placed on the plate body, and then the weight of the rotor causes the plate body to drop and squeeze the touch switch, and then the bidirectional electric push rod is started, and then the two pressure plates are driven to approach each other, and then the rotor is clamped across the conveyor belt. The clamping method is simple and easy to use. BRIEF DESCRIPTION OF THE DRAWINGS
