DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides a motor rotor magnetic core installation device, comprising a base 1, wherein a motor rotor clamping structure, a magnetic core assembly structure and a magnetic core conveying structure are sequentially arranged on the top of the base 1, and the magnetic core assembly structure is located between the motor rotor clamping structure and the magnetic core conveying structure. When the device is in use, the magnetic core conveying structure is used to convey the magnetic core to be assembled, the motor rotor clamping structure is used to clamp the motor rotor, and the magnetic core assembly structure is used to move and arrange the magnetic core, so that 10 magnetic cores can be inserted into the motor rotor at the same time, thereby improving the efficiency of assembling the magnetic core of the motor rotor.

[0025] The motor rotor clamping structure includes a rotating rod 3 movably connected to the base 1, a rotating motor 2 is fixedly connected to one end of the top of the base 1, and the end of the output shaft of the rotating motor 2 is fixedly connected to the middle of the bottom of the rotating rod 3 through a reducer. Through the setting of the rotating motor 2, the rotation of the rotating motor 2 can drive the rotating rod 3 fixedly connected thereto to rotate.

[0026] Clamping assemblies are provided at both ends of the rotating rod 1 3. Through the arrangement of the two clamping assemblies, the rotation of the rotating rod 1 3 can change the positions of the two clamping assemblies, so that when the device is in use, one motor rotor is being assembled at the assembly position, and another motor rotor can be clamped by another clamping assembly, so that the motor rotor can be quickly replaced, and the motor rotor located at the assembly position can be assembled during the removal of the assembled motor rotor, thereby improving the working efficiency of the device.

[0027] The supporting component includes a clamping base 4 fixedly connected to a rotating rod 3, and a positioning column 21 is fixedly connected to the middle part of the inner cavity of the clamping base 4. The motor rotor can be positioned by setting the positioning column 21, and the outer surface of the positioning column 21 is wrapped with an isolation pad, and the material of the isolation pad can be rubber. By setting the isolation pad, the friction between the positioning column 21 and the motor rotor can be increased, thereby improving the firmness of the connection between the motor rotor and the positioning column 21.

[0028] A hydraulic telescopic rod 18 is fixedly connected to the bottom of the inner cavity of the clamping base 4, and a positioning ring 19 is fixedly connected to the top of the hydraulic telescopic rod 18. The positioning ring 19 and the positioning column 21 are in a movably connected state. The extension and retraction of the hydraulic telescopic rod 18 can change the position of the positioning ring 19 fixedly connected thereto.

[0029] A positioning groove 24 is provided at the bottom end of the positioning column 21, and a limiting block is fixed on the inner wall of the positioning ring 19. The limiting block is movably connected to the inner cavity of the positioning groove 24. The distance value between the top of the limiting block and the top of the positioning ring 19 is the same as the distance value between the top of the inner cavity of the positioning groove 24 and the top of the clamping base 4. Through the setting of the limiting block and the positioning groove 24, when the limiting block contacts the top of the inner cavity of the positioning groove 24, the top of the positioning ring 19 and the top of the clamping base 4 can be at the same height, which is convenient for the placement of the motor rotor, and the positioning groove 24 can limit the positioning ring 19.

[0030] The top of the positioning ring 19 is evenly fixedly connected with a positioning block 20. Through the setting of the positioning block 20, the motor rotor can be positioned so that the positions of the motor rotors of the same batch placed on the clamping assembly remain consistent, which is convenient for the processing of the motor rotor.

[0031] The side wall of the above-mentioned clamping base 4 is a hollow structure, and the top of the inner cavity of the side wall of the clamping base 4 is evenly provided with through holes. A vacuum pump 23 is fixed to the top of the rotating rod 3. The air inlet end of the vacuum pump 23 is connected to the inner cavity of the side wall of the clamping base 4 through a vacuum tube 1, and an electric ball valve 14 is provided at one end of the vacuum tube 1. Through the setting of the vacuum pump 23, when the motor rotor is placed on the clamping assembly, the vacuum pump 23 can draw away the air between the motor rotor and the clamping base 4, so that the motor rotor is connected to the clamping base 4 under negative pressure, which is convenient for maintaining the stability of the motor rotor during the assembly process.

[0032] The core conveying structure can be a belt conveyor in the prior art, and slots 10 are evenly arranged on the conveyor belt 9 of the core conveying structure. A core adapted to the motor rotor is clamped in the inner cavity of the slot 10. When the device is in use, the core conveying structure is used to convey the core.

[0033] The magnetic core assembly structure includes a rotating rod 2 6 movably connected to the base 1, a rotating motor 2 5 is fixedly connected to the top of the base 1, and the end of the output shaft of the rotating motor 2 5 is fixedly connected to the rotating rod 2 6 through a reducer. Through the setting of the rotating motor 2 5, the rotation of the rotating motor 2 5 can drive the rotating rod 2 6 fixedly connected thereto to rotate. Both ends of the rotating rod 2 6 are provided with assembly components. In this way, when the rotating motor 2 5 rotates, the position between the two assembly components can change, and when one assembly component is located above the conveyor belt 9, the other assembly component and a clamping component are both located at the assembly position.

[0034] The assembly assembly includes a hydraulic telescopic rod 27 and a vacuum pump 16 fixedly connected to the rotating rod 26. The bottom of the hydraulic telescopic rod 27 is fixedly connected to a lifting sleeve 8, and the bottom end of the lifting sleeve 8 is movably connected to a rotating disk 11. Through the setting of the hydraulic telescopic rod 27, the extension and retraction of the hydraulic telescopic rod 27 can change the height of the rotating disk 11. The top of the inner cavity of the lifting sleeve 8 is fixedly connected to a rotating motor 17, and the end of the output shaft of the rotating motor 17 is fixedly connected to the top of the rotating disk 11 through a reducer. Through the setting of the rotating motor 17, the rotation of the rotating motor 17 can drive the rotating disk 11 fixedly connected thereto to rotate.

[0035] The outer ring at the bottom of the turntable 11 is evenly fixedly connected with a hydraulic telescopic rod 3 12, and the bottom of the hydraulic telescopic rod 3 12 is fixedly connected with a vacuum suction cup 22. The inner cavity of the vacuum suction cup 22 is connected to the air inlet end of the vacuum pump 16 through a vacuum tube 2 13, and an electric ball valve 14 is provided at one end of the vacuum tube 2 13. Through the setting of the hydraulic telescopic rod 3 12, the extension and contraction of the hydraulic telescopic rod 3 12 can change the position of the vacuum suction cup 22 fixedly connected thereto, and the vacuum suction cup 22 is adapted to the magnetic core. When the vacuum suction cup 22 contacts the magnetic core, the operation of the vacuum pump 1 16 can make the magnetic core and the vacuum suction cup 22 negatively connected, and the magnetic core can move with the vacuum suction cup 22, which is convenient for the assembly component to drive the magnetic core to be inserted into the magnetic core slot of the rotor.

[0036] A visual sensor 15 is provided in the middle of the bottom of the turntable 11. Through the setting of the visual sensor 15, the position between the vacuum suction cup 22 and the slot 10 can be detected, so that the vacuum suction cup 22 is in contact with the magnetic core thereunder.

[0037] From the above description of the assembly components, it can be seen that during the assembly of the magnetic cores and the replacement of the motor rotor, the assembly components located above the conveyor belt 9 can lift and discharge the magnetic cores, so that 10 magnetic cores can be inserted into the magnetic core slots at the same time, thereby improving the efficiency of the magnetic core assembly.

[0038] The material of the vacuum tube 1 and the vacuum tube 2 13 can both be bellows.

[0039] The electrical components involved in this application are all prior art, and technicians in this field are familiar with their connection methods. Through these technicians, all the electrical components in this application are connected to their compatible power supplies through wires, and according to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence are described below. The electrical connection is completed in a sequential working order, and the detailed connection means are well known in the art. The following mainly introduces the working principle and process, and no further explanation of the electrical control is given.

[0040] In summary, when the motor rotor magnetic core installation device is used, the motor rotor to be assembled is placed on the clamping assembly away from the conveyor belt 9, and the vacuum pump 23 is started. The operation of the vacuum pump 23 causes the motor rotor and the clamping assembly to be attracted by negative pressure, and the motor rotor and the clamping assembly are fixed together. After the motor rotor is fixed, the rotating motor 1 2 rotates, and the rotating motor 1 2 drives the fixed motor rotor to move until the motor rotor moves to the assembly position. During the fixing process of the motor rotor, the conveyor belt 9 drives the magnetic core to move and is located on the conveyor belt 9. The visual sensor 15 can locate the position of the magnetic core. When the magnetic core moves to the position directly below the vacuum suction cup 22 located above the conveyor belt 9, the conveyor belt 9 stops moving, and the hydraulic telescopic rod 3 12 connected to the vacuum suction cup 22 extends, and the hydraulic telescopic rod 3 12 drives the vacuum suction cup 22 to move downward until the vacuum suction cup 22 contacts the magnetic core, and the vacuum pump 16 is started. The operation of the vacuum pump 16 makes the vacuum suction cup 22 negatively connected to the magnetic core, and the hydraulic telescopic rod 3 12 contracts. The hydraulic telescopic rod 3 12 drives the magnetic core through the vacuum suction cup 22. The magnetic core is separated from the conveyor belt 9 by the rotary motor 17, and the rotation of the rotary motor 17 changes the position of the vacuum suction cup 22 until the other vacuum suction cup 22 moves to the top of the conveyor belt 9. During the rotation of the rotary motor 17, the conveyor belt 9 moves so that the other magnetic core can be moved to the bottom of the vacuum suction cup 22. After all the vacuum suction cups 22 of the assembly assembly are negatively connected to the magnetic core, the rotary motor 25 drives the rotating rod 26 to rotate until the magnetic core moves to the assembly position, and the hydraulic telescopic rod 1 18 contracts until the positioning block 20 moves into the inner cavity of the clamping base 4, the hydraulic telescopic rod 27 extends, the hydraulic telescopic rod 27 drives the magnetic core to move downward, and the magnetic core can be inserted into the magnetic core slot of the motor rotor, so that the magnetic cores are inserted into the magnetic core slots of the motor rotor at the same time, thereby improving the working efficiency of the equipment; after the magnetic core is inserted, the vacuum pump 16 stops working, the hydraulic telescopic rod 27 drives the vacuum suction cup 22 to move upward, the vacuum suction cup 22 and the magnetic core can be separated, and when the vacuum suction cup 22 moves to the top of the motor rotor, the magnetic core installation operation of the motor rotor is completed.

[0041] In addition, during the assembly process of the motor rotor, the clamping assembly far away from the assembly position can realize the taking and placing of the motor rotor, and the assembly assembly far away from the assembly position can lift the magnetic core to realize the neat arrangement of the magnetic core.
