Description

Technical Field

[0001] The present invention relates to the technical field of motor production, and in particular to a rotor cutting system for manufacturing a DC variable frequency motor and a use method thereof. Background Art

[0002] A variable frequency motor refers to a motor that can run continuously at 100% of the rated load in the range of 10% to 100% of the rated speed under standard environmental conditions, and the temperature rise will not exceed the rated allowable temperature of the motor.

[0003] The motor rotor is divided into two types: inner rotor rotation mode and outer rotor rotation mode. The inner rotor rotation mode refers to the core in the middle of the motor as a rotating body, outputting torque (referring to the motor) or receiving energy (referring to the generator). The outer rotor rotation mode uses the outer body of the motor as a rotating body. Different modes facilitate the application of various occasions. The rotor processing process includes: shaft riveting, cutting, oiling, and straightening;

[0004] At present, in the process of cutting the motor rotor, there are still the following shortcomings:

[0005] 1. During the cutting process of the motor rotor, if Fig.13 As shown, it is necessary to open slots with equal spacing on the rotor to facilitate the coil winding. However, when using cutting technology to cut the motor rotor, there is no corresponding cutting head, which makes the cutting process relatively troublesome.

[0006] 2. Furthermore, during the current process of cutting the motor rotor, the position of the motor rotor needs to be constantly adjusted. However, the existing method often uses manual adjustment, which is troublesome to operate, and it is difficult to accurately control the angle of the motor rotor during the adjustment process;

[0023] The method for using the rotor cutting system for manufacturing a DC variable frequency motor comprises the following steps:

[0024] S1. Rotor insertion

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

[0026] S2, limit and brake of mobile rack

[0027] Pull the moving frame downward to limit the rotating rod; the rotating clamping plate is clamped with the clamping shaft to brake the moving frame and stabilize the limited rotating rod; the tension spring is stressed when pulled, and the moving frame is driven to reset after the clamping is released.

[0028] S3, card cover height adjustment

[0029] The anti-loosening screw is turned to adjust the height of the card cover through thread transmission so that it can be clamped with the motor rotor; the anti-loosening screw and the anti-loosening nut are self-locking to maintain a stable clamping of the motor rotor.

[0030] S4, the cutter head is connected to the shaft

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

[0032] S5. Cutting head rotation and cutting

[0033] Start the drive motor to drive the shaft and the 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 thread transmission of the supporting screw, so that the cutter head cuts the motor rotor downward; the drive motor rotates in the reverse direction to drive the threaded tube to rotate in the reverse direction, so that the cutter head is reset.

[0034] S6. Coolant spraying and flushing

[0035] During the cutting process, the electric push rod is started to drive the mounting plate and the push plate to move upward, pushing the coolant to the delivery pipe; the coolant is delivered to the nozzle through the curved pipe and the moving pipe to spray out, flush the cutter head, flush out the waste chips and cool it down.

[0036] S7, motor rotor rotation adjustment

[0037] Start the stepper motor to drive the travel screw to rotate; through the thread transmission, drive the slide plate and the rack to move horizontally; drive the gear ring and the 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 hood, flows along the inclined panel, and is discharged through the drain pipe; the filter screen filters the waste chips; after use, pull the pull ring to move out of the inclined panel and collect the waste chips.

[0040] It is to be understood that the foregoing general description and the following detailed description are exemplary only and are not restrictive of the invention.

[0041] Compared with the prior art, the present invention has the following beneficial effects:

[0042] In the present invention, by means of the rotor adjustment mechanism, after the motor rotor is inserted into the support cover, the power assembly is started to drive the slide plate to move laterally along the support cover. At this time, the rack will also move laterally, and under the meshing transmission action with the gear ring, it can drive the support cover to rotate and adjust, and then drive the motor rotor to rotate and adjust. In this way, it is convenient to use the cutting mechanism to cut different positions of the motor rotor.

[0043] The present invention also provides a positioning mechanism, and when the two rotating rods are rotated, one end of them can be placed on the support frame. Then, the limit assembly is operated to position and brake the two rotating rods. After that, the anti-loosening screw is rotated, and the height of the card cover is adjusted through the threaded transmission effect between the anti-loosening screw and the anti-loosening nut, so that the card cover moves down to be clamped with the motor rotor. Since the anti-loosening screw and the anti-loosening nut have a self-locking property, when the card cover rotates with the motor rotor, it will not drive the anti-loosening screw to rotate, so that the motor rotor can be stably clamped.

[0044] In addition, the present invention is also provided with a cutting mechanism. When the positioning shaft is inserted into the positioning cover, the two clamping rods will penetrate the positioning ring. At this time, the rotating ring is released, and the torsion spring in a stressed state will drive the rotating ring to rotate, and the two positioning clamping blocks are inserted into the corresponding clamping holes to clamp and position the two clamping rods. In this way, the cutter head can be stably connected to the rotating shaft. When the driving motor is started to drive the rotating shaft to rotate, the cutter head will also rotate at high speed, thereby facilitating the cutting of the motor rotor.

[0045] In order to reduce the temperature during the cutting process and flush away the waste chips, the present invention also provides a cooling mechanism. After the coolant is injected into the coolant tank through the docking cover, the docking cover is rotated to correspond to the joint position, and then the docking cover and the joint are plugged. When cutting the motor rotor, the electric push rod is started to drive the mounting plate to move upward, and the push plate is driven upward by two limit racks to push the coolant into the delivery pipe. After being transported by the curved pipe and the moving pipe, the coolant will be sprayed out through the nozzle. Since the moving pipe can move longitudinally with the U-shaped plate, when cutting the motor rotor, the cutter head can be flushed, the cutter chips can be flushed out, and the cutter head can be cooled.

[0046] In summary, the present invention can conveniently perform cutting processing on the motor rotor through the modification of the cutter head and the setting of various mechanisms, and automatically rotate and adjust the motor rotor during the cutting process, which provides great convenience for the cutting processing.

[0062] The embodiments of the present invention are described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0063] In the description of the embodiments of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms, "connection" and "installation" should be understood in a broad sense. 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. In addition, "connection" can be a direct connection or an indirect connection through an intermediate medium. Among them, "fixed" means that they are connected to each other and the relative position relationship after connection remains unchanged. The directional terms mentioned in the embodiments of the present invention, such as "inside", "outside", "top", "bottom", etc., are only reference to the directions of the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present invention.

[0064] Example 1

[0065] Reference Figure 1-Figure 12A rotor cutting system for manufacturing a DC variable frequency motor in this embodiment includes a base 1. A vertical plate 14 is fixedly installed on one side of the top of the base 1. A support plate 62 is fixedly connected to one side of the vertical plate 14 for subsequent installation of a cutting mechanism.

[0066] A support cover 2 is installed at the top center of the base 1. The support cover 2 is connected to the top of the base 1 through 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 clamped 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, close 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 connections such as slide rails, so that it can move laterally along the support cover 7.

[0068] A rack 12 is fixedly mounted on the top of the slide plate 11, and a gear ring 13 is fixedly sleeved on the outer side of the support cover 2. The gear ring 13 is meshed with the rack 12 to ensure that the gear ring 13 and the support cover 2 can be driven to rotate when the rack 12 moves.

[0069] In order to drive the slide plate 11 to move laterally, a power assembly is installed on one side of the support cover 7, and the power assembly includes a stepper motor 8. The output shaft of the stepper motor 8 extends to the inside of the support cover 7 through a coupling and other connecting parts, and a travel screw 9 is fixedly installed. One end of the travel 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 threadedly connected to the travel screw 9, and 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, and 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 accordingly. 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 and adjust.

[0071] Next, install the positioning mechanism, which is installed on the other side of the top of the base 1 and 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 vertical plate 14 and provide a stable positioning effect.

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

[0073] Finally, a cooling mechanism is installed on the other side of the top of the vertical plate 14. The mechanism penetrates 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-mentioned specific implementation, a rotor cutting system for manufacturing a DC variable frequency motor is constructed, which can achieve precise cutting of the motor rotor 6 and provide stable support and cooling effects 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 strong enough to support the various components installed subsequently. On the support frame 4, a bracket 5 is further fixedly installed for preliminarily supporting the motor rotor 6. Two columns 3 are fixedly installed on both sides of the bracket 5. The 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 vertical plate 14, where two rotating rods 15 are symmetrically connected in rotation. During the rotation process, the 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 the rotation process.

[0077] In order to limit the two rotating rods 15, a set of limiting components is designed on the support frame 4, which includes two second support plates 21 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] In this frame, a moving frame 23 is slidably connected. The top of the moving frame 23 extends above the support frame 4, and its design purpose is to be able to press down on the two rotating rods 15 when necessary to brake and limit them. In order to ensure that the moving frame 23 can be stably raised and lowered, a tension spring 24 is sleeved on each limit rod 22, and the top and bottom ends of these tension springs 24 are fixedly connected to the support frame 4 and the moving frame 23 respectively, providing elastic support for the lifting and lowering of the moving frame 23.

[0079] In addition, in order to facilitate braking of the mobile 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 at the bottom of both sides of the mobile frame 23. These clamping shafts 26 match the clamping slots opened on the clamping plate 25. When the clamping shafts 26 are engaged with the clamping slots, the mobile 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, a locking nut 18 is fixedly installed. In the locking nut 18, a locking screw 19 is threadedly connected. The bottom end of the locking screw 19 extends to the bottom of the first support plate 17 and is rotatably connected to a card cover 20.

[0081] When the motor rotor 6 needs to be positioned, the motor rotor 6 is first placed on the bracket 5, and then the two rotating rods 15 are rotated to place one end of them on the support frame 4. Next, the movable frame 23 is pulled downward to limit the two rotating rods 15. After that, the two clamping plates 25 are rotated to clamp them with the corresponding clamping shafts 26, thereby braking the movable frame 23 and stably limiting the two rotating rods 15.

[0082] Finally, rotate the anti-loosening screw 19 and utilize the threaded transmission effect between it and the anti-loosening nut 18 to adjust the height of the card cover 20. When the card cover 20 moves down to be clamped with the top end 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 the self-locking property, even if the motor rotor 6 rotates during the subsequent processing, the card cover 20 will not drive the anti-loosening screw 19 to rotate, thereby maintaining a stable clamping of the motor rotor 6.

[0083] The core component of the cutting mechanism is the mounting frame 27 fixedly mounted on the top of the support plate 62. On the mounting frame 27, a slide rail or a similar sliding structure is designed 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 part.

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

[0085] A positioning cover 43 is fixedly mounted on one end of the rotating shaft 30. The positioning cover 43 has a plug-in structure inside for receiving and fixing the positioning shaft 41. One end of the positioning shaft 41 extends out of the positioning cover 43 and is fixedly mounted with a teardrop-shaped cutter head 38. The cutter head 38 is evenly distributed with a plurality of chip removal grooves 39, which are used to remove chips and prevent clogging during the cutting process.

[0086] On the positioning shaft 41, a fixing sleeve is provided with a mounting ring 40, and two clamping rods 42 are symmetrically installed on the side of the mounting ring 40 away from the cutter head 38. At the same time, a fixing sleeve is provided with a positioning ring 44 on the positioning cover 43, allowing the two clamping rods 42 to pass through. In addition, a rotating ring 46 is also designed, on which a positioning clamping block 47 is installed. When the rotating ring 46 rotates, the positioning clamping block 47 can be inserted into the clamping hole on the clamping rod 42, thereby realizing a stable connection between the cutter head 38 and the rotating shaft 30. In this process, the torsion spring 48 provides the rotating ring 46 with an automatic reset force.

[0087] In order to adjust the cutting depth, a worm 31 is fixedly sleeved on the rotating shaft 30. At the same time, a sliding bar 33 is designed in the mounting frame 27, on which two movable plates 32 are slidably connected. The rotating shaft 30 passes through the two movable plates 32, and two fixed plates 34 are fixedly connected between the two movable plates 32. A threaded tube 35 is rotatably installed between the two fixed plates 34. A worm wheel 36 meshing with the worm 31 is fixedly sleeved on the threaded tube 35. When the rotating shaft 30 rotates, the worm 31 drives the worm wheel 36 and the threaded tube 35 to rotate, and then the threaded tube 35 is longitudinally moved on the supporting screw 37 through the threaded transmission action. In this way, the entire cutting mechanism (including the cutter head 38) can move in the vertical direction, thereby adjusting the cutting depth.

[0088] Operation and effect: When the drive motor 29 is started, the cutter head 38 will rotate at high speed to cut the motor rotor 6 placed on the support plate 62. By adjusting the rotation 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 accurately controlled. The debris generated during the cutting process is discharged through the chip groove 39, ensuring the smooth progress of the cutting process. When it is necessary to stop cutting or adjust the cutting depth, the cutter head 38 can be stopped or reset by simply stopping the drive motor 29 or rotating it in the opposite direction.

[0089] A coolant tank 55 is fixedly installed on the other side of the vertical plate 14. A sliding space is designed inside the coolant tank 55. The push plate 58 is tightly installed in this space to ensure that the coolant does not leak. A rubber ring 59 is fixed to 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 frames 60 are fixedly installed at the bottom of the push plate 58. The bottoms of the two limit frames 60 are jointly connected to the mounting plate 61. The electric push rod 64 is fixed to the bottom of the vertical plate 14, and its output shaft is connected to the bottom of the mounting plate 61, so as to realize the up and down movement of the push plate 58.

[0090] A limit plate 63 is installed at the bottom of both sides of the coolant tank 55. The limit plate 63 extends to the inside of the limit frame 60 to ensure the stability of the limit frame 60 during movement. A delivery pipe 56 is arranged 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 vertical plate 14, one end of which is connected to the joint 54. The joint 54 and the docking cover 57 are designed to be sealably plugged in order to connect the coolant tank 55 and the bent pipe 53.

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

[0092] When in use, first inject the coolant into the coolant tank 55, and then rotate the docking cover 57 to align and plug it with the joint 54. During the cutting process, start the electric push rod 64 to push the mounting plate 61 and the limit frame 60 to drive the push plate 58 to move upward, thereby pushing the coolant into the delivery pipe 56, and then transporting it to the nozzle 52 through the curved pipe 53 and the moving pipe 51 for spraying. Since the moving pipe 51 is connected to the U-shaped plate 28, as the cutting process proceeds, the nozzle 52 can keep flushing the cutter head 38, effectively remove cutting waste and cool the cutter head.

[0093] A water cover 65 is fixedly installed on one side of the support plate 62. An inclined panel 66 is designed inside the water cover 65. A filter screen 68 is installed on the inclined panel 66. The filter screen 68 is in close contact with the inner walls on both sides of the water cover 65 to prevent waste chips 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 at the bottom of one side of the water cover 65 and is connected to an external coolant collection device.

[0094] During the cutting process, the coolant sprayed by the nozzle 52 falls into the water cover 65 after flushing the cutter head 38. The coolant flows along the inclined plate 66, filters out the waste chips through the filter screen 68, and is discharged to the external collection device through the drain pipe 69. When it is necessary to clean the waste chips 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] The present invention provides a method for using a rotor cutting system for manufacturing a DC variable frequency motor, comprising the following steps:

[0096] S1, inserting the motor rotor 6 to be cut into the support cover 2;

[0097] S2, pull the moving frame 23 downward, use the moving frame 23 to limit the rotating rod 15, and then rotate the two clamping plates 25 so that the clamping plates 25 and the corresponding clamping shafts 26 are clamped together, so that the moving frame 23 can be braked, so that the two rotating rods 15 can be stably limited, and when the moving frame 23 is pulled downward, the two tension springs 24 can be in a tensioned state, so after the clamping of the clamping plate 25 and the clamping shaft 26 is released, the tension springs 24 in a stressed state can drive the moving 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, the height of the card cover 20 can be adjusted, so that the card cover 20 moves down to be clamped with the motor rotor 6, and the anti-loosening screw 19 and the anti-loosening nut 18 have a self-locking characteristic, when the card cover 20 rotates with the motor rotor 6, the anti-loosening screw 19 will not be driven to rotate, so that the motor rotor 6 can be stably clamped;

[0099] S4. When the positioning shaft 41 is inserted into the positioning cover 43, the two clamping rods 42 can penetrate the positioning ring 44, and then the rotating ring 46 can be released. The torsion spring 48 in a stressed state can drive the rotating ring 46 to rotate, so that the two positioning clamping blocks 47 can be inserted into the corresponding clamping holes, and the two clamping rods 42 can be clamped and positioned, so that the cutter head 38 can be stably connected to the rotating shaft 30;

[0100] S5. When the drive motor 29 is started to drive the shaft 30 to rotate, the cutter head 38 can be driven to rotate at a high speed. When the shaft 30 rotates, the worm 31 can drive the threaded tube 35 to rotate under the meshing transmission action with the worm wheel 36. When the threaded tube 35 rotates, the threaded tube 35 can move longitudinally along the support screw 37 under the thread transmission action with the support screw 37, so that the cutter head 38 in a rotating state can move downward accordingly, so that the cutter head 38 can cut the motor rotor 6 when it moves downward, and when the drive motor 29 rotates in the reverse direction, the drive worm 31 can rotate in the reverse direction, so that the threaded tube 35 can be driven to rotate in the reverse direction, so that the cutter head 38 is reset upward.

[0101] S6. During the cutting of the motor rotor 6, the electric push rod 64 can be started to drive the mounting plate 61 to move upward. At this time, the push plate 58 can be driven upward by the two limit frames 60, so that the coolant can be pushed into the delivery pipe 56, and then the coolant can be delivered through the curved pipe 53 and the moving pipe 51, and can be sprayed out through the nozzle 52, and the moving pipe 51 can move longitudinally with the U-shaped plate 28, so when the motor rotor 6 is cut, the cutter head 38 can be flushed, so that the waste chips cut out can be flushed out, and the cutter head 38 can be cooled down at the same time;

[0102] S7, then start the stepper motor 8 to drive the travel screw 9 to rotate, at this time, under the threaded transmission action with the threaded plate 10, the slide plate 11 can be driven to move horizontally, thereby driving the rack 12 to move horizontally, so that the gear ring 13 and the support cover 2 can be driven to drive the motor rotor 6 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 the cutter head 38 is flushed. At this time, the coolant can flow along the inclined panel 66 and then be discharged from the drain pipe 69. The filter net 68 provided can filter the waste chips. After use, the inclined panel 66 can be removed by pulling the pull ring 67 so that the waste chips 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 conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.
