Description

Technical Field

[0001] This utility model relates to the field of iron core slot finding technology, and in particular to a rotor iron core slot finding mechanism. Background Technology

[0002] An electric motor is an electromagnetic device that converts or transmits electrical energy into mechanical energy based on the law of electromagnetic induction. It converts electrical energy into mechanical energy, and its main function is to generate driving torque. As a power source for electrical appliances and various machines, it is an indispensable device in our lives. The electric motor structure mainly consists of two parts: the stator and the rotor. The stator is generally composed of permanent magnets and is stationary. The rotor is the centrally rotating core, composed of a rotor core, rotor windings, and a shaft. When the motor is working, the coils on the rotor are energized, generating electromagnetic induction. This induction causes like poles to repel and unlike poles to attract with the permanent magnets on the stator, thus causing the rotor to rotate at high speed.

[0003] In the existing technology, the motor processing involves the alignment and pressing of the commutator. Before pressing, the rotor core needs to be aligned (angle). Currently, this alignment is mostly done manually, which is labor-intensive and inefficient for workers. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing a rotor core slot finding mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A rotor core slot-finding mechanism includes a base frame, on which a first lifting drive device is provided. The drive end of the first lifting drive device movably passes through the base frame and is provided with a support seat.

[0007] A mounting frame is provided on one side above the base frame, and a rotary drive device is provided on the mounting frame. A mechanical loading arm assembly is provided at the drive end of the rotary drive device.

[0008] A mounting plate is provided on one side above the base frame, and a first horizontal moving device is provided on one side of the mounting plate. The drive end of the first horizontal moving device movably passes through the mounting plate and is connected to the rear top assembly.

[0009] A second lifting drive device is provided above the base frame. A first connecting plate is provided at the drive end of the second lifting drive device, and a groove finding component is provided at the bottom end of the first connecting plate.

[0010] The slot-finding assembly includes a mounting block, a mounting slot, a spring, and a insert. The mounting block is located on one side of the first connecting plate, the mounting slot is located on one side of the mounting block, one side of the spring is located on one side of the inner cavity of the mounting slot, the insert is located on the other side of the spring, and a proximity switch is located on one side of the mounting block.

[0011] Preferably, the mechanical loading arm assembly includes a mechanical arm and several grippers, the mechanical arm being disposed at the drive end of the rotary drive device, and the several grippers being disposed at the drive end of the mechanical arm.

[0012] Preferably, the rear top assembly includes a second connecting plate and a top groove, the second connecting plate being disposed at the drive end of the first horizontal moving device, and the top groove being disposed at the bottom of the second connecting plate.

[0013] Preferably, the top groove is arc-shaped, and the second connecting plate is L-shaped.

[0014] Preferably, the support seat is provided with a support groove, and the support groove is arc-shaped.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention, through the provision of a lifting seat, allows the rotor to be lifted upwards by a first lifting drive device after it has been moved to a suitable position. Then, a first horizontal moving device moves the rear support assembly to press the rotor towards the mechanical loading arm assembly, which clamps one side of the rotor. A second lifting drive device then moves the connecting plate downwards, causing the mounting block to move downwards, bringing the insert into contact with the rotor. Once the insert is inserted into the rotor core slot by spring force, a proximity switch illuminates, stopping the rotation drive device. Compared to existing technologies, this device, through its rotation drive device, can rotate the rotor. A spring presses the insert against the rotor surface. When the insert is inserted into the rotor core slot by the spring force, the proximity switch illuminates, completing the slot finding process. This eliminates the need for manual slot finding, increasing work efficiency and solving the problems of high labor intensity and low efficiency in existing technologies. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1 to 5 A rotor core slot finding mechanism includes a base frame 1, on which a first lifting drive device 2 is provided, and the drive end of the first lifting drive device 2 movably passes through the base frame 1 and is provided with a support seat 3.

[0025] A mounting frame 4 is provided on one side above the base frame 1. A rotary drive device 5 is provided on the mounting frame 4. A mechanical loading arm assembly is provided at the drive end of the rotary drive device 5.

[0026] A mounting plate 6 is provided on one side above the base frame 1, and a first horizontal moving device 7 is provided on one side of the mounting plate 6. The driving end of the first horizontal moving device 7 movably passes through the mounting plate 6 and is connected to the rear top assembly.

[0027] A second lifting drive device 8 is provided above the base frame 1. A first connecting plate 9 is provided at the drive end of the second lifting drive device 8. A groove finding component is provided at the bottom end of the first connecting plate 9.

[0028] The slot-finding assembly includes a mounting block 10, a mounting groove 11, a spring 12, and a insert 13. The mounting block 10 is disposed on one side of the first connecting plate 9, the mounting groove 11 is disposed on one side of the mounting block 10, one side of the spring 12 is disposed on one side of the inner cavity of the mounting groove 11, and the insert 13 is disposed on the other side of the spring 12. A proximity switch 19 is disposed on one side of the mounting block 10. The first horizontal moving device 7, the first lifting drive device 2, and the second lifting drive device 8 are all cylinders, and the rotary drive device 5 is a rotary motor.

[0029] In use, this device can lift the rotor by moving the lifting seat 3 upward through the first lifting drive device 2. Then, the first horizontal moving device 7 can move the rear top assembly to push the rotor towards the mechanical loading arm assembly. The mechanical loading arm assembly clamps one side of the rotor. Then, the second lifting drive device 8 can move the connecting plate downward, which in turn moves the mounting block 10 downward, so that the insert 13 contacts the rotor. After the insert 13 is inserted into the rotor core slot by the force of the spring 12, the proximity switch 19 lights up, which will stop the rotation drive device 5. Compared with the prior art, this device can drive the rotor to rotate through the rotation drive device 5. The spring 12 presses the insert 13 on the surface of the rotor. When the insert 13 is inserted into the rotor core slot by the elastic force of the spring 12, the proximity switch 19 lights up, completing the slot finding. The slot finding is not required, which increases the work efficiency and solves the problems of high labor intensity and low efficiency in the prior art.

[0030] The proximity switch 19 is a sensor that can detect the presence of nearby objects without physical contact. It uses principles such as electromagnetic fields, sound waves, light beams, or capacitance changes to detect whether a target object is approaching its sensing range and triggers the switch accordingly. It includes both electromagnetic induction proximity switches 19 and capacitive proximity switches 19.

[0031] Furthermore, the mechanical loading arm assembly includes a mechanical arm 14 and several grippers 15. The mechanical arm 14 is located at the drive end of the rotary drive device 5, and the several grippers 15 are located at the drive end of the mechanical arm 14. The mechanical arm 14 can drive the several grippers 15 to clamp the rotor and prevent the rotor from shifting.

[0032] Furthermore, the rear top assembly includes a second connecting plate 16 and a top groove 17. The second connecting plate 16 is disposed at the driving end of the first horizontal moving device 7, and the top groove 17 is disposed at the bottom of the second connecting plate 16. The first horizontal moving device 7 can drive the second connecting plate 16 to move, and the top groove 17 can drive the rotor to move towards the side of the mechanical loading arm assembly.

[0033] Furthermore, the top groove 17 is arc-shaped, and the second connecting plate 16 is L-shaped. By setting the top groove 17 to be arc-shaped, the rotor can be better clamped and the rotor can be prevented from shifting.

[0034] Furthermore, the support seat 3 is provided with a support groove 18, and the support groove 18 is arc-shaped. The support groove 18 can support the rotor, and the arc-shaped support groove 18 can prevent the rotor from falling and damaging the rotor.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
