Description

Technical Field

[0001] The present invention relates to the field of rotor core processing, in particular to an automatic magnetic steel insertion device for processing automobile motor rotor cores. Background Art

[0002] Automotive motors usually refer to the electric motors in electric vehicles, which are used to drive the vehicle. Compared with traditional internal combustion engines, motors convert electrical energy into mechanical energy to drive the vehicle's wheels. Electric motors are usually more efficient than internal combustion engines and can provide instant torque output. The motor rotor core is one of the most critical parts of the motor. The main function of the rotor core is to provide a magnetic field to support the operating efficiency of the motor.

[0003] Common types of motors include DC motors, AC induction motors, permanent magnet synchronous motors, and synchronous motors. The rotor core of a permanent magnet synchronous motor requires magnets to be inserted into the rotor core during production. The main purpose of inserting magnets (or permanent magnets) into the rotor core is to enhance the motor's magnetic field and improve its performance. Therefore, automatic magnet insertion equipment used for automotive motor rotor core processing is required during the production of the motor rotor core.

[0004] When using the existing automatic magnetic steel insertion equipment for processing automobile motor rotor cores, the rotor core is manually placed on the operating table. During placement, the angle of the rotor core needs to be manually adjusted so that the limiting rod above the operating table can be inserted into the heat dissipation hole inside the rotor core, thereby limiting the rotor core and avoiding the problem of shaking of the rotor core when inserting the magnetic steel. However, the manual adjustment method is relatively cumbersome and time-consuming and labor-intensive, resulting in reduced work efficiency. It needs to be manually removed after processing is completed. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide an automatic magnetic steel insertion device for processing automobile motor rotor cores to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an automatic magnetic steel insertion device for processing automobile motor rotor cores, comprising a base, a conveying assembly is provided on one side of the base, and a support rod is installed on the top of the base through a bearing, a turntable is fixed at the end of the support rod, a plurality of groups of limiting columns are fixed on the top of the turntable, and a plurality of groups of fixing rods and a reset assembly are fixed on the top of the turntable, the outer wall of the limiting column is provided with a support disk, the ends of the support disk and the fixing rod are both inclined, a plurality of groups of fixing columns are fixed on one side of the top of the base, and a rubber roller is installed on the end of the fixing column, and a The first magnetic steel machine and the second magnetic steel machine, two groups of mounting frame structures are installed on the top of the conveying component, and a screw rod is movably installed inside the mounting frame structure, the outer wall of the screw rod is provided with a slider, a cylinder is installed at the bottom of the slider, and a mechanical gripper is installed at the output end of the cylinder, a driving component is provided on one side of the conveying component, and the driving component is connected to the support rod and the screw rod through the first transmission component and the second transmission component, the top of the limit column is higher than the top of the support disk, the top of the fixed rod and the top of the support disk are in the same plane, the number of the limit columns is four groups, and the four groups of limit columns are evenly distributed on the top of the turntable.

[0007] By adopting the above technical solution, the problem that the existing rotor core needs manual adjustment when being placed is solved. When the turntable rotates, the rotor core contacts the rubber roller, and under the action of friction, the rotor core rotates with the limit column as the center. When the rotor core rotates until the heat dissipation hole coincides with the fixed rod, the rotor core drives the support plate downward under the action of gravity. There is no need to manually align the position of the heat dissipation hole and the fixed rod, so that the rotor core is directly placed above the support plate. At the same time, the mechanical gripper is set to replace the manual loading and unloading method, which is more labor-saving and has higher work efficiency.

[0008] The present invention is further configured as follows: the first transmission assembly includes a transmission rod, a speed change gear box, a second bevel gear and a first bevel gear; a transmission rod is movably installed inside the conveying assembly; a speed change gear box is provided on the top of the base on one side of the support rod, and the output end of the speed change gear box is fixed with the second bevel gear; a connecting rod is installed at the input end of the speed change gear box, and a one-way bearing is provided at the end of the connecting rod, and the connecting rod is connected to the transmission rod through the one-way bearing; the outer wall of the support rod is provided with a first bevel gear, and the first bevel gear is meshed with the second bevel gear; the driving assembly is a driving motor, and the output end of the driving motor is connected to the transmission rod.

[0009] Preferably, when the driving motor is working, it will drive the transmission rod to rotate, and when the transmission rod rotates, it will drive the third pulley to rotate, and at the same time drive the connecting rod to rotate through the one-way bearing, and when the connecting rod rotates, it will drive the speed change gear box to work, and when the speed change gear box is working, the second bevel gear at the output end will rotate slowly, and the rotation of the second bevel gear will drive the first bevel gear to rotate, and the rotation of the first bevel gear will drive the support rod to rotate, and the rotation of the support rod will drive the turntable to rotate, and the rotation of the turntable will rotate the rotor core placed above the support disk, so that the rotor core will rotate to the bottom of the first magnetic steel machine and the second magnetic steel machine, which is convenient for processing the rotor core.

[0010] The present invention is further configured such that the second transmission assembly includes a second pulley, a third pulley and a second belt, the outer wall of the transmission rod is provided with a third pulley, a group of ends of the screw rods are installed with a second pulley, and the outer walls of the second pulley and the third pulley are provided with a second belt.

[0011] Preferably, when the transmission rod rotates, it will drive the third pulley to rotate. When the third pulley rotates, it will drive the second pulley to rotate through the second belt. The rotation of the second pulley will drive the screw to rotate. According to the screw principle, when the screw rotates, the slider mounted on the outer wall of the screw slides on the inner wall of the mounting frame structure. When the slider slides, it drives the mechanical gripper to move, reducing the use of the motor and improving the synchronization of the work.

[0012] The present invention is further configured such that a first pulley is fixed to the end of each of the two groups of screw rods, and a first belt is sleeved between the two groups of the first pulleys.

[0013] Preferably, when the transmission rod drives the screw rod to rotate through the second transmission assembly, the other set of screw rods will be driven to rotate with the cooperation of the first pulley and the first belt, so that the two sets of screw rods work at the same time, reducing the use of the motor.

[0014] The present invention is further configured such that the reset assembly includes an outer rod fixed to the top of the base, and an inner rod is movably mounted on the inner wall of the outer rod, a spring is fixed to the end of the inner rod, and the end of the spring is fixedly connected to the base.

[0015] Preferably, a reset assembly is set up, when the heat dissipation through-hole of the rotor core coincides with the fixed rod, the rotor core will squeeze the support plate under the action of gravity, and the support plate will move downward. When the support plate moves downward, it will drive the inner rod to slide on the inner wall of the outer rod, and the inner rod will squeeze the spring while sliding. When the bottom of the support plate contacts the top of the outer rod, the support plate stops moving. At this time, the fixed rod is inserted into the interior of the rotor core. When there is no rotor core above the support plate, the reset assembly can keep the top of the support plate and the top of the fixed rod at the same level under the action of the spring.

[0016] The present invention is further configured such that a through hole is opened in the middle of the support plate, and the inner wall of the through hole is in contact with the outer wall of the limiting column; multiple groups of guide holes are opened inside the support plate, and the inner walls of the guide holes are in contact with the outer wall of the fixing rod.

[0017] Preferably, the through hole is provided to enable the support plate to slide directionally on the outer wall of the limiting column, and the provision of the guide hole can facilitate the support plate to pass through the fixing rod.

[0018] The present invention is further configured such that the rubber rollers are provided in multiple groups, and the multiple groups of rubber rollers are evenly distributed on one side of the outer wall of the base.

[0019] Preferably, by providing multiple sets of rubber rollers, the rotor core can be better corrected, so that the rotor core that is not engaged with the fixing rod can be driven to rotate by the rubber rollers.

[0020] The present invention is further configured such that a plurality of support frames are fixed on the top of the base, and rollers are installed inside the support frames, and the rollers are in contact with the bottom of the turntable.

[0021] Preferably, rollers and support frames are provided below the turntable to support the turntable while reducing friction during its rotation, thereby avoiding deformation of the turntable caused by the rotor core placed above the turntable.

[0022] The present invention is further configured such that protrusions are fixed on both sides of the sliding block, and a sliding groove is provided inside the mounting frame structure.

[0023] Preferably, the provided protrusion cooperates with the slide groove so that the slider slides on the inner wall of the mounting frame structure, thereby avoiding the problem of deformation of the screw rod due to force.

[0024] The present invention is further configured such that four groups of limiting components can be fixed on the top of the turntable, and the limiting components include vertical rods, which are fixed on the top of the turntable and are configured in a cylindrical shape. There are three groups of vertical rods, and the three groups of vertical rods are evenly distributed on the inner wall of the through hole.

[0025] Preferably, the three groups of vertical rods are provided to reduce the contact area with the rotor core, thereby making it more convenient for the mechanical gripper to grasp the rotor core and reducing the friction between the vertical rods and the rotor core.

[0026] In summary, the present invention mainly has the following beneficial effects: The present invention solves the problem that the existing rotor core needs manual adjustment when it is placed by providing a turntable, a limit column, a fixing rod, a rubber roller and a support plate. When the turntable rotates, the rotor core contacts the rubber roller, and under the action of friction, the rotor core rotates with the limit column as the center. When the rotor core rotates until the heat dissipation hole coincides with the fixing rod, the rotor core drives the support plate downward under the action of gravity. There is no need to manually align the position of the heat dissipation hole and the fixing rod, so that the rotor core can be placed directly above the support plate. At the same time, the mechanical gripper provided replaces the manual loading and unloading method, which is more labor-saving and has higher work efficiency.

[0027] The present invention is provided with a drive motor, a transmission rod, a one-way bearing, a speed change gear box, a screw and a slider. A group of drive motors can simultaneously drive the turntable and the screw to rotate, reducing the use of motors and making the operation more synchronous. When the turntable rotates during loading, the setting of the speed change gear box can make the turntable rotate only 90 degrees. BRIEF DESCRIPTION OF THE DRAWINGS

There are four groups of limiting columns 33, and the four groups of limiting columns 33 are evenly distributed on the top of the turntable 3. By setting multiple groups of limiting columns 33, the multiple groups of support disks 8 can be better limited, thereby improving work efficiency.

[0033] In the above embodiment, please refer to Figure 1-Figure 3The first transmission assembly includes a transmission rod 68, a speed change gear box 12, a second bevel gear 611 and a first bevel gear 32. The transmission rod 68 is movably installed inside the conveying assembly 2. The speed change gear box 12 is provided on the top of the base 1 on one side of the support rod 31, and the output end of the speed change gear box 12 is fixed with the second bevel gear 611. The input end of the speed change gear box 12 is installed with a connecting rod 13, and the end of the connecting rod 13 is provided with a one-way bearing 14, and the connecting rod 13 is connected to the transmission rod 68 through the one-way bearing 14.

The driving assembly is a driving motor 69, and the output end of the driving motor 69 is connected to the transmission rod 68. The driving motor 69 works When the transmission rod 68 is rotated, the screw rod 62 and the turntable 3 can be driven to rotate by a driving motor 69, reducing the use of the motor. When the transmission rod 68 rotates, the third pulley 67 is driven to rotate, and the connecting rod 13 is driven to rotate through the one-way bearing 14. When the connecting rod 13 rotates, it drives the speed change gear box 12 to work. When the speed change gear box 12 works, the second bevel gear 611 at the output end rotates slowly. The rotation of the second bevel gear 611 drives the first bevel gear 32 to rotate. The rotation of the first bevel gear 32 will drive the support rod 31 to rotate. The rotation of the support rod 31 will drive the turntable 3 to rotate. The rotation of the turntable 3 will rotate the rotor core placed above the support disk 8, so that the rotor core rotates to the bottom of the first magnetic steel machine 4 and the second magnetic steel machine 5, which is convenient for processing the rotor core.

[0034] In the above embodiment, please refer to Figure 1 The second transmission assembly includes a second pulley 66, a third pulley 67 and a second belt 610. The outer wall of the transmission rod 68 is provided with a third pulley 67, and the end of a group of screw rods 62 is installed with a second pulley 66. The outer walls of the second pulley 66 and the third pulley 67 are provided with a second belt 610. When the transmission rod 68 rotates, it will drive the third pulley 67 to rotate. When the third pulley 67 rotates, it drives the second pulley 66 to rotate through the second belt 610. The rotation of the second pulley 66 drives the screw rod 62 to rotate. According to the screw rod principle, when the screw rod 62 rotates, the slider 61 mounted on the outer wall of the screw rod 62 slides on the inner wall of the mounting frame structure 6. When the slider 61 slides, it drives the mechanical gripper 10 to move, reducing the use of the motor and improving the synchronization of the work.

[0035] In the above embodiment, please refer to Figure 2 The ends of the two sets of screw rods 62 are fixed with first pulleys 63, and a first belt 64 is sleeved between the two sets of first pulleys 63. When the transmission rod 68 drives the screw rod 62 to rotate through the second transmission assembly, the cooperation of the first pulley 63 and the first belt 64 will drive the other set of screw rods 62 to rotate, so that the two sets of screw rods 62 work at the same time, reducing the use of motors.

[0036] In the above embodiment, please refer to Figure 5 and Figure 8 When the cam 35 is in the closed position, the cam 35 is in the closed position, and the cam 35 is in the closed position, so that the cam 35 is in the closed position.

[0037] In the above embodiment, please refer to Figure 5 and Figure 7 A through hole 81 is provided in the middle of the support plate 8, and the inner wall of the through hole 81 is in contact with the outer wall of the limiting column 33. A plurality of guide holes 82 are provided inside the support plate 8, and the inner wall of the guide hole 82 is in contact with the outer wall of the fixing rod 34. The through hole 81 can make the support plate 8 slide in a direction on the outer wall of the limiting column 33, and the setting of the guide hole 82 can facilitate the support plate 8 to pass through the fixing rod 34.

[0038] In the above embodiment, please refer to Figure 4 There are multiple groups of rubber rollers 71, and the multiple groups of rubber rollers 71 are evenly distributed on one side of the outer wall of the base 1. By setting up multiple groups of rubber rollers 71, the rotor core can be better corrected, so that the rotor core that is not matched with the fixing rod 34 can be driven to rotate through the rubber rollers 71.

[0039] In the above embodiment, please refer to Figure 3 Multiple groups of support frames 9 are fixed on the top of the base 1, and rollers 91 are installed inside the support frames 9. The rollers 91 are in contact with the bottom of the turntable 3. The turntable 3 is supported below by the provided rollers 91 and the support frames 9. While supporting the turntable 3, the friction force of the turntable 3 is reduced when it rotates, thereby avoiding the problem of deformation of the turntable caused by the rotor core placed above the turntable 3.

[0040] In the above embodiment, please refer to Figure 2 and Figure 6, protrusions 612 are fixed on both sides of the slider 61, and a slide groove 65 is opened inside the mounting frame structure 6. The protrusions 612 are matched with the slide groove 65 to make the slider 61 slide on the inner wall of the mounting frame structure 6, avoiding the problem of deformation of the screw rod 62 due to force. Example 2

[0041] See also Figure 10 Four groups of limiting components can also be fixed on the top of the turntable 3. The limiting components include vertical rods 36. The vertical rods 36 are fixed on the top of the turntable 3, and the vertical rods 36 are arranged in a cylindrical shape. There are three groups of vertical rods 36. The three groups of vertical rods 36 are evenly distributed on the inner wall of the through hole 81. The top of the vertical rods 36 is arranged with an inclined surface. The vertical rods 36 with an inclined surface can better place the rotor core when it is placed, so that the rotor core is placed in the center of the support disk 8. The three groups of vertical rods 36 can reduce the contact area with the rotor core, so that the mechanical gripper 11 is more convenient to grab the rotor core, and the friction between the vertical rods 36 and the rotor core is reduced.

[0042] The present invention works specifically as follows: when in use, the personnel places the rotor core on top of the conveying assembly, and then starts the conveying assembly. The conveying assembly drives the rotor core to move. When the rotor core moves to the bottom of a set of mounting frame structures 6, the conveying assembly stops working, and the two sets of cylinders 10 work at the same time to drive the mechanical gripper 11 to move downward. The mechanical gripper 11 moves downward to grab the rotor core, and then the cylinder 10 drives the rotor core to move upward. After reaching the position, the cylinder 10 stops working, and then the drive motor 69 is started. When the drive motor 69 works, it drives the transmission rod 68 to rotate. When the transmission rod 68 rotates, it drives the third pulley 67 to rotate. At the same time, it drives the connecting rod 13 to rotate through the one-way bearing 14. When the connecting rod 13 rotates, it drives the speed change gear box 12 to work. When the speed change gear box 12 works, the second bevel gear 611 at the output end rotates slowly, and the rotation of the second bevel gear 611 drives the first bevel gear When the gear 32 rotates, the rotation of the first bevel gear 32 drives the support rod 31 to rotate. The rotation of the support rod 31 drives the turntable 3 to rotate. When the third pulley 67 rotates, it drives the second pulley 66 to rotate through the second belt 610. The second pulley 66 rotates to drive the screw rod 62 to rotate. According to the screw rod principle, when the screw rod 62 rotates, the slider 61 sleeved on the outer wall of the screw rod 62 slides on the inner wall of the mounting frame structure 6. When the screw rod 62 rotates, it drives the first pulley 63 to rotate. The first pulley 63 rotates through the first belt 64 to drive another set of screw rods 62 to rotate. When the other set of screw rods 62 rotates, it drives the other set of sliders 61 to move. The two sets of sliders 61 approach each other, and then the screw rod 62 rotates, causing the two sets of sliders 61 to move away from each other. One set of mechanical grippers is used to grab the processed rotor core, and the other set of mechanical grippers is used to grab the processed rotor core, and the processed rotor core is removed from the top of the support plate 8.

[0043] When the slider 61 moves to the other end inside the mounting frame structure 6, the drive motor 69 stops working. When the drive motor 69 stops working, the transmission rod 68 and the screw rod 61 also stop working. The stopping of the transmission rod 6 will cause the speed change gear box 12 to stop working. At this time, the turntable 3 rotates 90 degrees, and the empty support plate 8 above the turntable 3 moves to the bottom of the mechanical gripper 11. The rotor core after the magnet is inserted at the second magnet machine 5 moves to the bottom of another set of mechanical grippers 11. Then the two sets of cylinders 10 are started at the same time. The cylinder 10 drives the mechanical gripper 11 to drive the rotor core to move downward. The processed rotor core falls above the conveying assembly 2, and the unprocessed rotor core falls above the support plate 8. Under the action of the limit column 33, the processed rotor core is sleeved on the outer wall of the limit column 33.

[0044] When the heat dissipation through-hole of the rotor core coincides with the fixed rod 34, the rotor core will squeeze the support plate 8 under the action of gravity, and the support plate 8 will move downward. When the support plate 8 moves downward, it will drive the inner rod 352 to slide on the inner wall of the outer rod 351. When the inner rod 352 slides, it will squeeze the spring 353. When the bottom of the support plate 8 contacts the top of the outer rod 351, the support plate 8 stops moving. At this time, the fixed rod 34 is inserted into the interior of the rotor core; at the same time, the first magnetic steel machine 4 and the second magnetic steel machine 5 work at the same time to insert magnets into the rotor core. The hydraulic rods on one side of the first magnetic steel machine and the second magnetic steel machine drive the chassis to move downward, and the chassis and the rotor core are in contact. The top of the core contacts, and then the telescopic rod drives the insertion rod downward to insert the magnetic steel into the interior of the rotor core. When the mechanical gripper 11 puts down the rotor core, the cylinder 10 drives the mechanical gripper 11 to reset. At this time, the drive motor 69 reverses. When the drive motor 69 reverses, it will drive the slider 61 to reset. When the drive motor 69 reverses, it will drive the transmission rod 68 to rotate. Under the action of the one-way bearing 14, the connecting rod 13 does not rotate at this time. After the slider 61 is reset, the conveying component 2 works to transport the processed rotor core to the next processing technology, and transports the newly processed rotor core to the bottom of the mechanical gripper 11, and then repeats the above steps.

[0045] If the processed rotor core is placed above the support plate 8, the heat dissipation holes of the rotor core do not coincide with the fixing rod 34. At this time, the top of the fixing rod 34 contacts the bottom of the rotor core, and the support plate 8 will not move. Then the driving motor 69 works to move the newly processed rotor core. At this time, the turntable 3 rotates. When the turntable 3 rotates slowly, the outer wall of the rotor core will contact the rubber roller 71. The rubber roller 71 contacts the rotor core, and the friction force will cause the rotor core to rotate with the limiting column 33 as the center of the circle. When the rotor core rotates to the point where the heat dissipation holes coincide with the fixing rod 34, the rotor core will move downward under the action of its own gravity. At this time, the fixing rod 34 is inserted into the heat dissipation holes of the rotor core. Repeat the above operation to realize the operation of inserting the magnet into the rotor core, which is more labor-saving.
