Description

Technical Field

[0001] This invention relates to the field of motor manufacturing technology, and in particular to a rotor cutting system for manufacturing DC inverter motors and its usage method. Background Technology

[0002] A variable frequency motor is a motor that, under standard environmental conditions, operates continuously at 100% rated load within a speed range of 10% to 100% of the rated speed without exceeding the motor's rated allowable temperature.

[0003] Motor rotors are classified into two types: internal rotor rotation and external rotor rotation. Internal rotor rotation refers to the core of the motor as the rotating body, outputting torque (for electric motors) or receiving energy (for generators). External rotor rotation uses the outer body of the motor as the rotating body. These different methods facilitate applications in various situations. The rotor manufacturing process includes: shaft riveting, cutting, oiling, and straightening.

[0004] Currently, the following shortcomings still exist in the process of cutting motor rotors:

[0005] 1. During the cutting process of the motor rotor, such as Figure 13 As shown, equally spaced slots need to be made on the rotor to facilitate coil winding. However, currently, when using cutting technology to cut the motor rotor, there is no corresponding cutting tool, making the cutting process relatively troublesome.

[0006] 2. Furthermore, during the cutting process of the motor rotor, it is necessary to continuously adjust the position of the motor rotor. However, the existing methods often use manual adjustment, which is cumbersome and makes it difficult to accurately control the angle of the motor rotor during the adjustment process.

[0007] To address the aforementioned problems, this invention proposes a rotor cutting system for manufacturing DC inverter motors and its usage method. Summary of the Invention

A drain pipe is fixedly installed through the bottom inner wall of one side of the drain cover, and one end of the drain pipe is connected to an external coolant collection device.

[0023] The method of using the rotor cutting system for manufacturing DC inverter motors includes the following steps:

[0024] S1, Rotor insertion

[0025] Insert the motor rotor that needs to be cut into the support cover.

[0026] S2, Moving frame limit and braking

[0027] Pull the moving frame downward to limit the rotation rod; the rotating plate engages with the clamping shaft to brake the moving frame and stabilize the rotation rod; the tension spring is stressed when pulled, and after the engagement is released, it drives the moving frame to reset.

[0028] S3, Card Cover Height Adjustment

[0029] Rotate the anti-loosening screw to adjust the height of the clamping cover through the threaded transmission, so that it is clamped to the motor rotor; the anti-loosening screw and anti-loosening nut are self-locking, maintaining stable clamping of the motor rotor.

[0030] S4. Connection between the cutter head and the rotating shaft

[0031] Insert the positioning shaft into the positioning cover so that the locking rod passes through the positioning ring; release the rotating ring, and the torsion spring will drive it to rotate. Insert the positioning block into the locking hole to lock the positioning locking rod and stably connect the cutter head and the rotating shaft.

[0032] S5, Tool rotation and cutting

[0033] Start the drive motor to drive the shaft and cutter head to rotate; the worm rotates with the shaft and meshes with the worm wheel to drive the threaded tube to rotate; the threaded tube moves longitudinally under the threaded transmission of the support screw, causing the cutter head to cut the motor rotor downward; the drive motor rotates in the opposite direction to drive the threaded tube to rotate in the opposite direction, causing the cutter head to reset.

[0034] S6. Coolant spraying and flushing

[0035] During the cutting process, the electric push rod is activated, which drives the mounting plate and push plate to move upward, pushing the coolant to the delivery pipe; the coolant is delivered to the nozzle through the bend pipe and the moving pipe, rinsing the cutter head, flushing out the waste chips and cooling it down.

[0036] S7, Motor rotor rotation adjustment

[0037] Start the stepper motor to drive the stroke screw to rotate; through the threaded transmission, drive the slide plate and rack to move laterally; drive the gear ring and support cover to adjust the rotation of the motor rotor so as to cut different positions.

[0038] S8. Waste Collection and Treatment

[0039] The coolant sprayed during the cutting process falls into the water inlet cover, flows along the inclined panel, and is discharged through the drain pipe; the filter screen filters out the waste chips; after use, pull the pull ring to remove the inclined panel and collect the waste chips.

[0040] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the invention.

[0041] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0042] In this invention, through the rotor adjustment mechanism, after the motor rotor is inserted into the support cover, the power assembly is activated to drive the sliding plate to move laterally along the support cover. At this time, the rack also moves laterally, and under the meshing transmission action with the gear ring, it can drive the support cover to rotate and adjust, thereby driving the motor rotor to rotate and adjust. In this way, the cutting mechanism can be used to easily cut different positions of the motor rotor.

[0043] This invention also includes a positioning mechanism. When the two rotating rods are rotated, one end of each rod can be placed on the support frame. Then, the limiting component is operated to position and brake the two rotating rods. Afterward, rotating the anti-loosening screw, through its threaded transmission with the anti-loosening nut, adjusts the height of the clamping cover, causing it to move down to engage with the motor rotor. Due to the self-locking characteristic between the anti-loosening screw and the anti-loosening nut, the clamping cover will not cause the anti-loosening screw to rotate as it rotates with the motor rotor, thus maintaining a stable clamping of the motor rotor.

[0044] Furthermore, this invention also includes a cutting mechanism. When the positioning shaft is inserted into the positioning cover, the two locking rods pass through the positioning ring. At this time, the rotating ring is released, and the torsion spring, under stress, drives the rotating ring to rotate, inserting the two positioning blocks into their corresponding locking holes to lock and position the two locking rods. In this way, the cutter head can be stably connected to the rotating shaft. When the drive motor is started and drives the rotating shaft to rotate, the cutter head will also rotate at high speed, thereby facilitating the cutting of the motor rotor.

[0045] To reduce the temperature during the cutting process and flush away waste chips, this invention also includes a cooling mechanism. After the coolant is injected into the coolant tank through the docking cover, the docking cover is rotated to align with the joint position, and then the docking cover is inserted into the joint. During the cutting of the motor rotor, an electric push rod is activated, moving the mounting plate upwards. Two limit brackets then move the push plate upwards, pushing the coolant into the delivery pipe. After being conveyed through the curved and moving pipes, the coolant is sprayed out through the nozzle. Because the moving pipe can move longitudinally with the U-shaped plate, the cutting head can be flushed during the cutting of the motor rotor, flushing out the cutter chips and cooling the cutting head.

[0046] In summary, by modifying the cutting head and setting up various mechanisms, this invention enables convenient cutting of motor rotors and automatically adjusts the rotation and positioning of the motor rotor during the cutting process, greatly facilitating the cutting process.

[0062] The embodiments of the present invention will now be described with reference to the accompanying drawings.

[0063] In the description of the embodiments of the present invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "installation" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the devices are connected to each other and their relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of the present invention, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of the present invention.

[0064] Example 1

[0065] Reference Figures 1-12The rotor cutting system for manufacturing DC inverter motors according to this embodiment includes a base 1. A vertical plate 14 is fixedly installed on one side of the top of the base 1, and a support plate 62 is fixedly connected to one side of the vertical plate 14 for subsequent installation of the cutting mechanism.

[0066] At the top center of the base 1, a support cover 2 is installed. The support cover 2 is connected to the top of the base 1 by rotating connectors such as bearings to ensure free rotation. The bottom end of the motor rotor 6 is designed to extend into the interior of the support cover 2 and be tightly fitted with the inner wall of the support cover 2 to ensure the stability of the motor rotor 6 during rotation.

[0067] At the top of the base 1, adjacent to one side of the support cover 2, a support cover 7 is fixedly installed. Inside the support cover 7, a slide plate 11 is designed. The slide plate 11 is connected to the inner wall of the support cover 7 through sliding connectors such as slide rails, so that it can move laterally along the support cover 7.

[0068] A rack 12 is fixedly installed on the top of the slide plate 11, and a toothed ring 13 is fixedly fitted on the outside of the support cover 2. The toothed ring 13 meshes with the rack 12 to ensure that the toothed ring 13 and the support cover 2 can rotate when the rack 12 moves.

[0069] To drive the slide plate 11 to move laterally, a power assembly is installed on one side of the support cover 7. The power assembly includes a stepper motor 8. The output shaft of the stepper motor 8 extends into the interior of the support cover 7 through a coupling or other connecting parts, and a stroke screw 9 is fixedly installed thereon. One end of the stroke screw 9 is rotatably connected to the inner wall of one side of the support cover 7 to ensure its stability. A threaded plate 10 is threaded onto the stroke screw 9. The top of the threaded plate 10 extends to the top of the support cover 7 and is fixedly connected to the slide plate 11.

[0070] When the position of the motor rotor 6 needs to be adjusted, the stepper motor 8 is started. The stepper motor 8 drives the stroke screw 9 to rotate. Due to the threaded transmission between the threaded plate 10 and the stroke screw 9, the threaded plate 10 will drive the slide plate 11 to move laterally along the support cover 7. At this time, the rack 12 fixed on the top of the slide plate 11 also moves. Through the meshing transmission with the gear ring 13, the gear ring 13 and the support cover 2 will rotate, thereby driving the motor rotor 6 to rotate for adjustment.

[0071] Next, install the positioning mechanism, which is installed on the other side of the top of the base 1. It is used to clamp and position the motor rotor 6 to ensure the stability of the motor rotor 6 during the cutting process. The specific structure of the positioning mechanism can be designed according to actual needs, but it should ensure that it can be connected to the top of one side of the upright plate 14 and provide a stable positioning effect.

[0072] A cutting mechanism is installed on the top of the support plate 62. This mechanism is used to perform precise cutting on the motor rotor 6. The specific structure of the cutting mechanism can be designed by selecting appropriate cutting tools, motors and transmission mechanisms according to the cutting requirements.

[0073] Finally, a cooling mechanism is installed on the other side of the top of the vertical plate 14. This mechanism passes through the vertical plate 14 and is connected to the cutting mechanism. During the cutting process, the cooling mechanism will spray coolant into the cutting area to reduce the cutting temperature and prevent the motor rotor 6 from being damaged due to high temperature.

[0074] Through the above specific implementation methods, a rotor cutting system for manufacturing DC inverter motors is constructed. This system can achieve precise cutting of the motor rotor 6 and provide stable support and cooling during the cutting process, thereby improving cutting accuracy and processing efficiency.

[0075] On the other side of the top of the base 1, a support frame 4 is fixedly installed. The support frame 4 is designed to be sturdy enough to support the various components to be installed later. On the support frame 4, a bracket 5 is further fixedly installed to initially support the motor rotor 6. On both sides of the bracket 5, two columns 3 are fixedly installed respectively. These two columns 3 are also firmly fixed to the top of the base 1, thereby enhancing the structural strength of the entire positioning mechanism.

[0076] Next, notice the top of one side of the upright plate 14, where two rotating rods 15 are symmetrically connected. During rotation, these two rotating rods 15 can be placed on the support frame 4 to provide a basis for subsequent limiting operations. At the same time, a connecting rod 16 is fixedly installed on the two rotating rods 15, which helps to maintain the synchronization of the two rotating rods 15 during rotation.

[0077] In order to limit the two rotating rods 15, a limiting assembly is designed on the support frame 4. This limiting assembly includes two second support plates 21 that are symmetrically fixed on the support frame 4. A limiting rod 22 is fixedly installed on the top of each second support plate 21. The top ends of these limiting rods 22 are fixedly connected to the support frame 4 to form a stable frame.

[0078] Within this frame, a movable frame 23 is slidably connected. The top of this movable frame 23 extends above the support frame 4, and its design allows it to be pressed down onto the two rotating rods 15 for braking and limiting when needed. To ensure stable raising and lowering of the movable frame 23, a tension spring 24 is fitted onto each limiting rod 22. The top and bottom ends of these tension springs 24 are fixedly connected to the support frame 4 and the movable frame 23, respectively, providing elastic support for the raising and lowering of the movable frame 23.

[0079] In addition, to facilitate braking of the movable frame 23, a clamping plate 25 is rotatably connected to one side of each second support plate 21. At the same time, a clamping shaft 26 is fixedly installed on the bottom of both sides of the movable frame 23. These clamping shafts 26 match the slots opened on the clamping plates 25. When the clamping shafts 26 are engaged with the slots, the movable frame 23 can be braked.

[0080] On the side where the two rotating rods 15 are close to each other, a first support plate 17 is rotatably connected. On the top of the first support plate 17, an anti-loosening nut 18 is fixedly installed. Inside the anti-loosening nut 18, an anti-loosening screw 19 is threaded through. The bottom end of the anti-loosening screw 19 extends to the bottom of the first support plate 17 and is rotatably connected to a retainer 20.

[0081] When it is necessary to position the motor rotor 6, first place the motor rotor 6 on the bracket 5, then rotate the two rotating rods 15 and place one end of them on the support frame 4. Next, pull down the moving frame 23 to limit the two rotating rods 15. Then, rotate the two clamping plates 25 to engage with the corresponding clamping shafts 26, thereby braking the moving frame 23 and stably limiting the two rotating rods 15.

[0082] Finally, rotate the anti-loosening screw 19 and use its threaded transmission with the anti-loosening nut 18 to adjust the height of the clamping cover 20. When the clamping cover 20 moves down to engage with the top of the motor rotor 6, the positioning of the motor rotor 6 is completed. Since the anti-loosening screw 19 and the anti-loosening nut 18 have a self-locking characteristic, even if the motor rotor 6 rotates during subsequent processing, the clamping cover 20 will not drive the anti-loosening screw 19 to rotate, thus maintaining a stable clamping of the motor rotor 6.

[0083] The core component of the cutting mechanism is the mounting bracket 27, which is fixedly mounted on the top of the support plate 62. The mounting bracket 27 is designed with a slide rail or similar sliding structure to allow the U-shaped plate 28 to slide freely in the vertical direction. The U-shaped plate 28 is designed to support and fix the subsequent drive mechanism and the cutter head.

[0084] Installation and connection of drive motor: A drive motor 29 is fixedly installed on one side of the U-shaped plate 28. The output shaft of the drive motor 29 passes through the corresponding openings of the U-shaped plate 28 and the mounting bracket 27, and is finally firmly connected to the rotating shaft 30. In this way, when the drive motor 29 starts, its power can be directly transmitted to the rotating shaft 30.

[0085] A positioning cover 43 is fixedly installed at one end of the rotating shaft 30. The positioning cover 43 has an internal plug-in structure for receiving and fixing the positioning shaft 41. One end of the positioning shaft 41 extends out of the outer side of the positioning cover 43 and is fixedly installed with a teardrop-shaped cutting head 38. Multiple chip removal grooves 39 are evenly distributed on the cutting head 38. These grooves are used to remove chips during the cutting process and prevent clogging.

[0086] A mounting ring 40 is fixedly sleeved on the positioning shaft 41. Two locking rods 42 are symmetrically mounted on the side of the mounting ring 40 away from the cutter head 38. At the same time, a positioning ring 44 is fixedly sleeved on the positioning cover 43, allowing the two locking rods 42 to pass through. In addition, a rotating ring 46 is designed, on which a positioning block 47 is mounted. When the rotating ring 46 rotates, the positioning block 47 can be locked into the locking hole on the locking rod 42, thereby realizing a stable connection between the cutter head 38 and the rotating shaft 30. During this process, the torsion spring 48 provides an automatic reset force for the rotating ring 46.

[0087] To adjust the cutting depth, a worm gear 31 is fixedly mounted on the rotating shaft 30. Simultaneously, a slide bar 33 is designed within the mounting bracket 27, on which two movable plates 32 are slidably connected. The rotating shaft 30 passes through these two movable plates 32, and two fixed plates 34 are fixedly connected between the two movable plates 32. A threaded tube 35 is rotatably mounted between the two fixed plates 34. A worm wheel 36, meshing with the worm gear 31, is fixedly mounted on the threaded tube 35. When the rotating shaft 30 rotates, the worm gear 31 drives the worm wheel 36 and the threaded tube 35 to rotate. This, in turn, causes the threaded tube 35 to move longitudinally on the supporting screw 37 through threaded transmission. Thus, the entire cutting mechanism (including the cutter head 38) can move vertically, thereby adjusting the cutting depth.

[0088] Operation and Effect: When the drive motor 29 starts, the cutter head 38 will rotate at high speed to cut the motor rotor 6 placed on the support plate 62. By adjusting the speed of the drive motor 29 and the transmission ratio of the worm 31 and the worm wheel 36, the cutting speed and cutting depth can be precisely controlled. The chips generated during the cutting process are discharged through the chip removal groove 39, ensuring the smooth progress of the cutting process. When it is necessary to stop cutting or adjust the cutting depth, simply stop the drive motor 29 or reverse its rotation to stop or reset the cutter head 38.

[0089] A coolant tank 55 is fixedly installed on the other side of the upright plate 14. The coolant tank 55 has a sliding space inside, and the push plate 58 is tightly installed in this space to ensure that the coolant does not leak. A rubber ring 59 is fixed on the top of the push plate 58, which is in close contact with the inner wall of the coolant tank 55 to further improve the sealing performance. Two limit brackets 60 are fixedly installed on the bottom of the push plate 58. The bottom of the two limit brackets 60 are connected to the mounting plate 61. An electric push rod 64 is fixed on the bottom of the upright plate 14, and its output shaft is connected to the bottom of the mounting plate 61 to realize the up and down movement of the push plate 58.

[0090] Limiting plates 63 are installed on both sides of the bottom of the coolant tank 55. The limiting plates 63 extend into the interior of the limiting frame 60 to ensure the stability of the limiting frame 60 during movement. A delivery pipe 56 is provided on the top of the coolant tank 55. The delivery pipe 56 is rotatably connected to the coolant tank 55 through a bearing. A docking cover 57 is installed at the top of the delivery pipe 56. A bent pipe 53 is installed on the upright plate 14. One end of the bent pipe 53 is connected to a connector 54. The connector 54 and the docking cover 57 are designed to be sealed and plugged in to connect the coolant tank 55 and the bent pipe 53.

[0091] A movable tube 51 is tightly slidably connected to the bent tube 53. A nozzle 52 is installed at the bottom of the movable tube 51, and the nozzle 52 is directly opposite the position of the cutter head 38. The movable tube 51 is fixedly connected to the top of the U-shaped plate 28 through the fixing bracket 50 and two mounting rods 49, so that the movable tube 51 can move with the movement of the U-shaped plate 28.

[0092] In use, first inject coolant into the coolant tank 55, then align and insert the docking cover 57 with the connector 54 by rotating it. During the cutting process, start the electric push rod 64 to push the mounting plate 61 and the limit bracket 60 to move the push plate 58 upward, thereby pushing the coolant into the delivery pipe 56. The coolant is then delivered to the nozzle 52 through the bend pipe 53 and the moving pipe 51. Since the moving pipe 51 is connected to the U-shaped plate 28, the nozzle 52 can keep rinsing the cutting head 38 as the cutting process progresses, effectively removing cutting chips and cooling the cutting head.

[0093] A drain cover 65 is fixedly installed on one side of the tray 62. The drain cover 65 has an inclined panel 66 inside. A filter screen 68 is installed on the inclined panel 66. The filter screen 68 is in close contact with the inner walls of both sides of the drain cover 65 to prevent waste from leaking out. A pull ring 67 is installed on the top of the inclined panel 66 for easy removal and cleaning. A drain pipe 69 is installed on the bottom of one side of the drain cover 65 and is connected to an external coolant collection device.

[0094] During the cutting process, the coolant sprayed from the nozzle 52 washes the cutter head 38 and falls into the water sump 65. The coolant flows along the inclined plate 66, filters out the waste material through the filter screen 68, and is discharged to the external receiving and collecting device through the drain pipe 69. When it is necessary to clean the waste material on the filter screen 68, the inclined plate 66 and the filter screen 68 can be pulled out as a whole through the pull ring 67 for cleaning and maintenance.

[0095] This invention proposes a method for using a rotor cutting system for manufacturing DC inverter motors, comprising the following steps:

[0096] S1. Insert the motor rotor 6 that needs to be cut into the support cover 2;

[0097] S2. Pull the movable frame 23 down to limit the rotation rod 15. Then, rotate the two clamping plates 25 so that the clamping plates 25 are engaged with the corresponding clamping shafts 26. This can brake the movable frame 23 and stably limit the two rotation rods 15. When the movable frame 23 is pulled down, the two tension springs 24 are in a tensile state. So, after the clamping plates 25 and the clamping shafts 26 are released, the tension springs 24, which are in a tensile state, can drive the movable frame 23 to move upward and reset.

[0098] S3. Rotating the anti-loosening screw 19, under the threaded transmission action with the anti-loosening nut 18, can adjust the height of the clamping cover 20, so that the clamping cover 20 moves down to clamp with the motor rotor 6. Furthermore, the anti-loosening screw 19 and the anti-loosening nut 18 have a self-locking characteristic. When the clamping cover 20 rotates with the motor rotor 6, it will not drive the anti-loosening screw 19 to rotate, thereby maintaining a stable clamping of the motor rotor 6.

[0099] S4. When the positioning shaft 41 is inserted into the positioning cover 43, the two locking rods 42 can pass through the positioning ring 44. Then the rotating ring 46 can be released. The torsion spring 48 under force can drive the rotating ring 46 to rotate, so that the two positioning blocks 47 can be inserted into the corresponding locking holes to lock and position the two locking rods 42, thereby enabling the cutter head 38 to be stably connected to the rotating shaft 30.

[0100] S5. When the drive motor 29 is started and drives the rotating shaft 30 to rotate, it can drive the cutter head 38 to rotate at high speed. When the rotating shaft 30 rotates, the worm 31 rotates with the rotating shaft 30. Under the meshing transmission action with the worm wheel 36, it can drive the threaded tube 35 to rotate. When the threaded tube 35 rotates, under the thread transmission action with the support screw 37, the threaded tube 35 can move longitudinally along the support screw 37. This allows the rotating cutter head 38 to move downwards. When the cutter head 38 moves downwards, it can cut the motor rotor 6. When the drive motor 29 rotates in the opposite direction, it can drive the worm 31 to rotate in the opposite direction. This can drive the threaded tube 35 to rotate in the opposite direction, so that the cutter head 38 returns to its original position.

[0101] S6. During the cutting process of the motor rotor 6, the electric push rod 64 can be activated to drive the mounting plate 61 to move upward. At this time, the push plate 58 is driven upward by the two limit brackets 60, so that the coolant can be pushed into the delivery pipe 56. After being delivered by the bend pipe 53 and the moving pipe 51, the coolant can be sprayed out through the nozzle 52. The moving pipe 51 can move longitudinally with the U-shaped plate 28. Therefore, when cutting the motor rotor 6, the cutting head 38 can be flushed, so that the cutting chips can be flushed out and the cutting head 38 can be cooled.

[0102] S7. Next, start the stepper motor 8 to drive the stroke screw 9 to rotate. At this time, under the thread transmission with the threaded plate 10, the slide plate 11 can be driven to move laterally, which in turn can drive the rack 12 to move laterally. Thus, under the transmission action of the gear ring 13 and the support cover 2, the motor rotor 6 can be driven to rotate and adjust so as to cut different positions on the motor rotor 6.

[0103] S8. During the cutting process of the cutter head 38, the sprayed coolant will fall into the water cover 65 after rinsing the cutter head 38. At this time, the coolant can flow along the inclined plate 66 and then be discharged through the drain pipe 69. The filter screen 68 can filter the waste. After use, the inclined plate 66 can be moved out by pulling the pull ring 67 so that the waste can be collected.

[0104] However, as is well known to those skilled in the art, the working principles and wiring methods of the stepper motor 8, drive motor 29 and electric push rod 64 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0105] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. In the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
